Question about storing bitcoin with a private key.

I’m looking to move my bitcoin off CoinBase to an address that I can hold the private key for.
Am hoping to get some advice from you all, or confirmation that this plan will work:
  1. Use an offline copy of www.bitaddress.org to generate an Address+PrivateKey combo. Place both into an encrypted file, and store copies of it in multiple physical locations.
  2. Slowly buy bitcoin using CoinBase, and periodically send them to the address generated from Step1.
  3. Visit www.blockchain.com/btc/address/xxxxxxxxxxxxx to see that transactions from CoinBase completed successfully.
  4. After 10+ years, buy whatever the newest Ledger hard wallet is available, and “sweep” the bitcoins from my address into the new hard wallet.
I’m not looking to be trading/selling/using it anytime within the next 10 years, so the idea is to have the simplest setup that doesn’t require maintaining any hardware/software wallets for the next 10 years while I slowly accumulate bitcoin. I won’t have to install any software, or update hard wallet firmware or anything like that.
Questions:
Is an Address+PrivateKey all that is needed to sweep the coins from my address into a new Ledger or a software wallet when the time comes?

Partially redeeming a Casascius physical bitcoin - help request

Overview of problem
I have a Casascius physical bitcoin and I am unable to add its digital contents to a wallet. It seems that the key is not the right length or format. I started to get out of my depth with talk of things like a Minikey format.
I removed the hologram when I was given it years ago as I was curious what was under there. I don't want to sell it instead I want to add its 1 BTC value to a wallet so I can partially redeem it and keep the physical brass as a collectible.
What I have observed and tried (apologies in advance for butchering terms)
I've searched several sites, including here and haven't been able to find a current answer for the new style of keys and wallets.
I put the seven character code from the hologram into the casascius.uberbills dot com site and it gives me a 33 character key, tells me it's version 2 and confirms that it has a 1 BTC value
I've tried to import it into a Blockchain wallet but get the error "this private key does not match the watch only address above" when I enter the private key under the hologram. For some reason it seems like a different public address is generated when I enter the 33 char code.
I tried to import it into a Jaxx Liberty wallet but it doesn't recognise the minikey or 33 char code as valid.
I've basically run up against my level of knowledge and don't know what the next steps are of if I'm missing something bleeding obvious. I double and triple checked any data entry because I saw this was a common problem.
I'd really appreciate any help or pointers the community can give me.
Thanks
Edit:
Solution
I followed the advice given by u/murbul in reply to my post
You might struggle to find a wallet that natively supports MINI keys these days since it's an old format that never really took off apart from Casascius coins. So your best bet is to use a tool to convert it to a real private key (starting with 5) and import/sweep that into a wallet.
You can convert it on the Wallet Details tab of https://www.bitaddress.org/ - For 1 BTC I'd be paranoid enough to recommend downloading the source and doing everything offline: https://github.com/pointbiz/bitaddress.org
I used the site and one of the keys generated was one starting with '5' (Private Key WIF). I used this in Jaxx Liberty in the 'Paper Wallet Import' function under tools and it came right across.
I’m very happy.

How to Cold Store Your Cryptocurrency for Safekeeping

According to CipherTrace (which specializes in litigation tools and services for cryptographic markets), between 2018 and 2019, the amount of theft from cryptographic wallets exceeds $2 billion. Thefts and break-ins are caused by a variety of reasons: simple incompetence in cryptographic storage, as well as by companies that provide storage services. It is not unusual for holders of crypto currency to lose access to their wallets by themselves, one of the last known cases occurred in Ireland: ,57 million dollars couldn’t be confiscated from a detained drug dealer, which were stored in bitcoins. The problem was that the wallets keys were lost.
The most secure way is a cold storage — all account data and private keys are kept offline and all transactions are manual. This storage method is great because it is fully protected from hacking and interception of data, but it is not suitable for those who make daily transfers of cryptocurrency, it is simply inconvenient.
If you compare “cold and hot” wallets, you can give a simple example: A hot wallet can be compared to a wallet that can be lost and stolen. But you can always access your funds. A cold wallet is safe, and access to it is not permanent. You can also take or put money, but it will require a special code.
In this article we will tell you about the most popular types of cold wallets and we will analyze their pros and cons.

Types of cold wallets

All cold wallets have one common thing — the data is stored offline. However, there are several types of cold wallets, which differ in the degree of protection, physical embodiment and cost of the wallet.

Desktop wallet

Desktop wallets are also known for a high level of protection, in addition to the ability to store crypto currency offline. There are so-called “light” wallets weighing less than 1 gb, and “heavy” wallets weighing more than 1 gb. Two of the desktop wallets can be distinguished:

Exodus Wallet

Multicurrency wallet. It was created in 2016 and supports more than 100 crypto currencies, since 2019 has a phone application. The wallet allows you to export private keys that are created locally, and then to upload them back. Private keys can be discounted to removable media and downloaded only when the transaction is completed. If the user decides to leave private keys on the same computer where the wallet is located, keys are securely encrypted. In order to use your wallet ,there is no need to register or to download the entire blockchain — synchronization is taking place online. In addition to wallet services Exodus Wallet provides an integrated crypto-exchange. The installation file weighs 85 mb.

Bitcoin Core

Bitcoin Core is the official Bitcoin wallet. The size of the wallet is 160 gb, but according to the developers of the company, it’s better to give it a separate winchester with the size of 500 gb. From the security viewpoint, it’s suggested to install a security code or a seed phrase, which may consist 8 words. It is also suggested to copy wallet.dat file. — private wallet key, which will allow you to restore access to your funds.

Hardware wallets

Appears like a regular flash drive with an interface (screen, control keys). This wallet can safely store information about the balance and keys, full functionality is available only when connected to a computer, but the latest models have a special button that allows you to confirm the transaction without connecting to a PC. Each time the device offers to generate a new code-password to confirm the transaction, which significantly reduces the probability of hacking. After generating the code, you need to set a mnemonic phrase (seed) — it consists of 12 or 24 words, which are not related to each other in any way. Such type of wallets has a special protection system that allows you to connect even to potentially infected PCs. The wallets themselves won’t be affected by malware.
The obvious cons of hardware wallets are the following:
  1. It is also possible to lose a device that is so small in size.
  2. A physical device can easily fail due to a variety of damages.
  3. It is not recommended to buy such wallets from “hand”, even from friends, as they can be pre-installed with malware.
As you can see, storing crypto currency with a hardware wallets is very safe and secure, however you should take care about the device. Many people who hold a large amount of crypto currency, in order to not to lose a hardware wallet, store it in a safe deposit box, depriving someone of access to it.

Popular Hardware Wallets models

Trezor One

The first hardware wallet produced in 2013 by the Czech company Satoshi Labs. The device has an OLED display with a pin code, public addresses and Seed phrases. Trezor One has won recognition from users due to its multicurrency and affordable price ($65), it is also considered one of the most secure hardware wallets.
Ledger Nano S
The wallet was released in 2016 by the French company Ledger SAS. Distinctive feature from the other wallets, is the Secure Element controller, which meets banking standards and is certified CC EAL 5+. Also, in order to work with each crypto currency you need to install a special application for this currency on the device, it is not quite convenient, however more secure. The average price of the device is $85.
KeepKey
The purse was released in 2015 in the U.S.. Distinctive feature is OLED display — 256 by 64 pixels. Due to this, you can fully see both the address of the wallet, and the seed phrase. Also, the wallet has a built-in exchange service ShapeShift — an opportunity to exchange crypto currency without entering the exchange. The average price of the device is $50.
BitBox01
Ionos Schnelly’s wallet was invented in Switzerland. In size it’s almost the most compact among all representatives of the hardware wallets. A distinctive feature is the availability of a backup — the card can be multiplied and kept in several places, by analogy with the seed-phrase. In November 2020, support for these wallets will be discontinued, but all owners will be given a 30% discount on the new model. The average price of the device is $55.
CoolWalletS
Developed in Taiwan by CoolBitX, which has long been manufacturing components for Visa and MasterCard. As well as Ledger Nano S has a security standard CC EAL 5+. This wallet works only through smartphones, connecting to them through Bluetooch. The average price of the device is $100.

Paper Wallet

In the age of technological process, plain paper has become a rather reliable method for storing cryptocurrency. With the help of special services, such as bitaddress.org, you can generate public and private keys, then writing them down on paper. You can also print keys as a QR code. To accept transactions with such a wallet, you provide the sender with a public key. To access the funds, you need to find any online wallet that supports your crypto currency. Enter your private key into your online wallet, thus integrating your funds into the system. However, you should understand that after this procedure your wallet will become “hot”.
The best of this storage method — paper wallet is free, its safety depends only from you. When storing a paper wallet to protect it from the fire, water and aging. Also, do not tell other people about where your paper wallet is hidden.
The disadvantages of this storage:
  1. If your wallet is lost, it will be impossible to restore it.
  2. Exposed to a physical damage.
  3. After sending the transaction, you will have to create a new cold wallet.

Offline transaction signature

For this storage method, you will need two PCs. The essence is that the secret keys are never in contact with the Internet, but are stored digitally. Offline transaction method is suitable for people who do not make a daily transactions and have an access to two devices. The process is below:
  1. A hot wallet is installed on a PC with the Internet. The transaction is created without entering private keys and authorization.
  2. The file with transaction is copied and transferred to the second PC without Internet, where private keys are stored.
  3. The transaction is signed offline, copied and transferred back to the PC with the Internet.
In fact, you can do it with one PC and a USB drive. The USB drive will store private keys. Also, you can create a transaction without entering private keys and authorization, after disconnecting the Internet, connect the flash drive, sign the transaction, turn on the Internet. In this case, you should take care of the antivirus system.
The disadvantages of this method:
  1. Using two PCs or a USB drive involves a lot of actions, which is time consuming.
  2. You need to back up your keys in case your PC or flash drive fails.

Multi-signature wallet

This method implies the creation of a wallet, which can be only withdrawn on condition that the transaction is verified by a predetermined number of users. The maximum number of users who can hold private keys of the wallet- is 15. It is considered as one of the most reliable ways of storage, in fact private keys are not only stored offline, but also divided between different people. Often the wallet with multisignatures is used by large crypto-companies, whose management believes that individually employees can not spend the budget. Moreover, when creating this wallet, the number of required multisignatures is minimal. For example: if one of the six keys is lost, the remaining ones will be enough for the transaction.
The disadvantages of this storage:
  1. If most of the keys are lost, access to the funds cannot be restored.
  2. You will not be able to make transactions on your own without the participation of other key holders.

Private Key Fragmentation

The private wallet key consists of 64 symbols. The key is divided into several fragments. They don’t represent anything separately, but if you put all the fragments together, you can access the funds. The key fragments are similar to multisignatures, but in this case you don’t need a multisig-wallet, and the whole process can be done manually.
The disadvantages of this method:
  1. If one fragment is lost, access to funds will be lost.
  2. The maximum level of protection can only be reached when key fragments are distributed to different places, for example: bookshelf, safe deposit box, car. If you divide the key fragments and put them in different boxes — the required level of protection will not be achieved.
When writing down key fragments on paper, protect the key from fire, water and aging.

Conclusion

Digital currencies are not physically expressed and exist only in the digital code, so cold wallets that doesn’t have an access to the Internet, protect cryptocurrencies from the most important and common problem — hacker theft. However, holders of cold wallets need to understand that the safety of a private key depends only on them. There are different ways to store private keys outside the network, but each of them makes it difficult for the user to make transactions.
Hardware wallets that have been specifically designed for this purpose are considered to be the best option for storing cryptocurrencies. With their help it is possible both to store funds off the network and to make transactions easily, without risking the safety of a private key. If you use other cold wallets, it is recommended to combine them with hot wallets. Keep the required crypto currency for daily transfers on hot wallets, and keep all other crypto on cold wallets.

Forks, and how to quickly cash out of them

I just saw a post on this subreddit talking about how to quickly check all forked coins from a bitcoin address, should it still hold the coins of course.
A small intro to the subject for newcomers: https://coincodex.com/article/7891/confronting-the-difference-between-bitcoin-and-altcoins/
With that out of the way, and thanks to u/Thanatos_1 for building this:
"The easiest way imo is to
1) get a new cold storage setup, for example a hardware wallet.
2) sending everything to the new cold storage and waiting a good 6 to 10 confirmations
3) install Coinomi on an Android device and set it up with all the shitcoin airdrops it supports. That's at least: BitcoinCash, BitcoinGold, BitcoinPrivate, BitcoinSV, Bitcore and Clams.
4) open www.bitaddress.org, wiggle around, click on the "Wallet Details" tab
5) copy and paste the now empty private key(s) into the "Enter Private Key" field to display its QR code
6) scan the private key(s) with the Coinomi shitcoin wallets to sweep them into your Coinomi wallet.
7) Go to coinmarketcap.com and find exchanges that actually trade that crap for BTC. Tip, use a throwaway e-mail-address and no identifying information. These exchanges are shady af.
8) Send your BTC gains to a different cold storage wallet. You can also check out Forkdrop.io to see if its worth your while to claim other shitcoin airdrops that are not supported by Coinomi."
Now, I wonder if there's a simpler way to do it though? In my opinion it's already simple enough, but I can see how the many steps might not be optimal for some. All ideas are welcome!

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.
https://preview.redd.it/86nocaff0mh31.jpg?width=720&format=pjpg&auto=webp&s=7a6d4e9a4ef9945eec416583d487e5553c4377e9

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.

  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.

  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.

  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.

  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.

  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.

  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.

https://preview.redd.it/e13whvvl0mh31.png?width=1024&format=png&auto=webp&s=8ee93d65adfcee76b0f8043c6ae1e4c022c16c0b

  • Mist
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain.
Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.

  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.

  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.

https://preview.redd.it/4iyn26do0mh31.png?width=1604&format=png&auto=webp&s=7a9d58bb81911aa336aa93320dbdae5f763d4a3e

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.

  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.

  • WalletGenerator.net
The core of this key-generating wallet is 99% identical to the well-considered bitaddress.org.First of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.

How to keep your wallet in security?

Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
  • Choose a wallet that suits your requirementsAll wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.
  • Keep your private key safeAlways make sure that your private key is secure and is stored in a safe place. Moreover, do not share your private keys. No, not with friends. Not even with your parents.

Paper Wallet Vanity addresses.

EDIT 2/21/2020. I am no longer offering the service described below as I no longer have access to the necessary hardware.
~~~~~~~~~~
Hey all,
I have recently been messing around with vanity addresses for paper wallets. After a little tinkering I got the system working well and can generate wallets up to a certain complexity quite reliably.
I've been able to generate wallets like this one: 1Bitcoinjqekek8HwmT8Cp8ojH9b7Quhzi
This one: 1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6
And this one: 1Genesisud7wjt8Lkto75ANupmviwC2wpW
I personally haven't been using paper wallets for cold storage until now, but with the value of BSV going up and also having read the following paper about the possibility (albeit very small) of compromise of private keys in HD wallets, that for the BSV I intend to sit on long term, it's probably not the worst idea ever to use a paper wallet for that. But hey, it would be nice if those addresses were a bit more recognizable than a random address, am I right? :)
In going through this exercise, I happened to notice that there are services out there that will generate these kinds of addresses, but they seem overly expensive!
e.g., At vanity.coin.dance they want 1 BTC(!!) to generate an address starting with "Satoshi" e.g., like the "1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6" I generated above. That's day-light robbery!!
Furthermore, the above service treats split key generation (which seems necessary for security when having a third party generate the wallet) as an "advanced" feature only. Imagine paying 1 BTC for an address only to have the private key compromised! (Seems almost negligent).
So anyway, whilst I have this system set up and working, I was thinking I could extend a temporary offer to anyone who is interested in getting a vanity address (or addresses) for paper wallet cold storage.
So all that said, the procedure, following the secure split key approach, would be as follows.
  1. You would go to bitaddress.org and download a local copy of the web site (and validate it against provided signatures).
  2. Run that downloaded copy of web site on an off-line system.
  3. Click the Vanity Wallet Tab.
  4. Click the "Generate" button in Step 1.
  5. Copy the public key from Step 1 and PM me with that key (it's quite long so copy/paste is the way to go). Also indicate in the PM the address prefix that you want (can't include invalid characters; I will tell you if you included any). Be sure to keep a copy of the private key from Step 1 (or keep the web page open). If you lose this key the whole process will be for nothing. Do not lose (or compromise) it (and definitely do not PM it to me!).
  6. Send payment (as per the schedule below) to 1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6 and PM me the TxID.
  7. When I receive payment, I will generate a partial private key that you need for Step 2 in the bitaddress.org page.
  8. You take the partial private key that you generated in Step 1 (that you keep secure and never shared with anyone) and paste it into the first box in Step 2 in the Bitaddress.org page (that you are still running locally and off-line).
  9. Finally, you paste the partial private key that I PM you back, into the text box where it says "Enter Pool Part Private Key (from Vanity Pool):" (Note: PMing this partial private key is fine; so long as you keep your partial private key secure (from Step 1), the process is still secure; the process is intended to work this way).
  10. Click "Calculate Vanity Wallet" et viola! A wallet will be produced that meets your prefix requirement and is 100% secure since the partial private key that you generated in Step 1 never left your control.
What you do with your new shiny address from that point on-wards is your prerogative, the same as any other paper wallet that you produce. Our deal is done.
The pricing schedule for this (temporary) service is as follows:
  1. 3 Characters (e.g.,) 1BSVxxxx....xxx 0.01 BSV.
  2. 4 Characters (e.g.,) 1Coinxxx....xxx 0.02 BSV.
  3. 5 Characters (e.g.,) 1Coinsxx....xxx 0.04 BSV.
  4. 6 Characters (e.g.,) 1BuyBSVx....xxx 0.1 BSV.
  5. 7 Characters (e.g.,) 1Satoshi....xxx 0.75 BSV1.
(Footnote 1: Turns out most 7 character combinations are pretty hard to generate and may take quite a while to generate. The prefix "1Bitcoin", however, is not as hard (higher chance of generating), and I can do that one for 0.25 BSV).
(Note: I can't guarantee that I can deliver anything longer than 7 characters, hence there is no price for this).
(Note: The reason for the steep increase in price as a function of number of prefix characters is the time it takes to generate the addresses as they become exponentially more complex and the fact the process is non deterministic).
Compare the above price for a 1Satoshi... address (0.75BSV) to vanity.coin.dance (1BTC!!!) and hopefully you'll see that I'm being pretty reasonable with this, though do note that the "1Satoshi" prefix, specifically, is a hard one to generate and I may not be able to do it unless you are willing to wait a while.
Anyway, I'm not sure if anyone will be interested in this, and you'll have to trust me as someone who has been in this sub since the total membership was only in double digits, that I'm not a fly by night scammer who is going to take your payment and run! To that end I advise that I have made posts in this sub with direct reference to my Australian based registered business that accepts BSV as payment, so it's not hard to track me down. If you go back far enough you'll also see that I was involved in running a Bitstagram competition and came good with the BSV prize in that case. That said, a small amount of trust will be required if this is going to work out. Test me with one of the cheaper options first, if you have doubts.
Terms and Conditions
  1. Any PM received with an "order" is an offer by you to purchase a vanity address. It's not binding until I accept the offer in writing (by PM).
  2. All "orders" will be processed in the order they are received; I will guarantee a 48 hour turn around for everything up to 6 characters and 1681 hours (7 days) for 7 characters. In reality most will be processed much quicker, but I have to cover my ass! If I get too many orders (unlikely!!) I reserve the right to reject any that I cannot meet in a timely manner (any payments that have been made will be refunded to the specified address, less any BSV Tx fees).
  3. This offer is on the table until I withdraw it. I may withdraw it at any time by making a follow up post to this sub edit to this post.
  4. The address that is generated is the address that you get and that is final. If there is something in the address that you don't like (like a random swear word; albeit very unlikely) we can discuss a discounted rate to have a second try at it. (I'd rather you go home happy, if possible).
  5. If there is some address that I cannot generate in the above guaranteed time frames (some are harder to produce than others), I will let you know by PM and refund your entire purchase price.
  6. The entire risk of the use of the generated vanity address lies with you. (I recommend you test it with a small amount and make sure you can withdraw it, before loading it up for real).
(T&C Footnote 1: Some 7 character combinations can take a long time to find (e.g., "1Satoshi") and may take up to two weeks or more! I reserve the right to not even attempt to generate any specific combination that could adversely affect my ability to turn it around in a reasonably timely manner. In that case you can choose a different prefix or I will refund your money, if at that stage you had already paid). For any potential prefix I can check the estimated time to generate and report back on whether it's reasonable, before we agree to go ahead.)
ps/ Here are two three addresses that I generated showing that funds are able to be deposited and withdrawn successfully.
https://blockchair.com/bitcoin-sv/address/1Satoshi3A43v3Jk9MpfJPUDrWadFUUP6
https://blockchair.com/bitcoin-sv/address/1Bitcoinjqekek8HwmT8Cp8ojH9b7Quhzi
https://blockchair.com/bitcoin-sv/address/1BuyBSVMHGx6dSTpLMhALXvEPVEDMStxoR
Both addresses accepted funds and both allowed the BSV to be successfully swept (in this case I used Simply Cash to deposit and sweep).

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.
https://preview.redd.it/ovlczorz6mh31.jpg?width=720&format=pjpg&auto=webp&s=eba30a80ba4fd2928272f3fa8dcef39da0177a8f

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.

  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.

  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.

  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.
https://preview.redd.it/rtvnw6p37mh31.png?width=1088&format=png&auto=webp&s=46fdf6af91d12fccc41d5a0d3fe3ee32ffce61dd

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.

  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.

  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.
  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.
https://preview.redd.it/a810i9277mh31.png?width=1024&format=png&auto=webp&s=6b57cce28966819ea9922675e0c64180996eb9da

  • Mist
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain
Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.

  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.
  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.
https://preview.redd.it/75o14iff7mh31.png?width=1604&format=png&auto=webp&s=280cdfaf6ea98e90f626e7bd9e2c3edbf2fd6ba2

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.

  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.

  • WalletGenerator.net
The core of this key-generating wallet is 99% identical to the well-considered bitaddress.org.First of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.

How to keep your wallet in security?

Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
  • Choose a wallet that suits your requirementsAll wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.
  • Keep your private key safeAlways make sure that your private key is secure and is stored in a safe place. Moreover, do not share your private keys. No, not with friends. Not even with your parents.
  • Set up 2-factor authenticationSome wallets offer this feature to increase the security of your coins. Do not ignore 2-factor authentication, set it up for extra confidence in protection against theft.
  • Backup, backup, and backupNothing protects you better from unforeseen accidents than a good old backup. This way you can keep access to your coins.
  • Store your funds offlineWith all the security levels offline wallets are still the most secure ones. Therefore, it is better to keep large amounts of ETH coins only on offline wallets.

Money Loves Security And So Do Cryptos: A Brief Guide Down Crypto Wallet Lane

Since time immemorial people have been keeping their money and valuables in safe places. Be they purses, clay pots full of coins buried in their backyards or treasure chests hidden in caves with piles of bones strewn around to keep unwanted visitors at bay, they means conceived for safekeeping hoarded valuables are just as creative as they are limitless.
The advent of cryptocurrencies as a new class of valuables and assets instantly spawned the need to keep them safe from the clammy hands of criminals. The logical solution was to develop wallets that would be used to keep cryptos safe. As a result, a multitude of wallets have emerged offering all kinds of added services to their users while remaining means of storage at heart.
There is a huge variety of wallets available: Coinomi, GreenAddress, Blockchain.info, Atomic, Exodus, Jaxx, Electrum, Copay, Bread, Airbitz, Armory, Mycelium, Blockchain Wallet and dozens of others, each offering their services to suit any taste.
https://preview.redd.it/tai1ax5q3u341.jpg?width=1200&format=pjpg&auto=webp&s=0a33622327c7e52eea02e77f7c843423e6aeba12

Types Of Wallets

There are several types of wallets available to users and everyone must decide for themselves which one suits their needs best.
Hardware wallets: These are the most secure and reliable wallets available, since they are not connected to the internet at all. Hardware wallets are like flash memory cards that store the user’s cryptocurrencies and access offline. A bright example is the Trezor wallet, which is deemed to be impermeable to hackers. Unless the user loses the device itself, it is safe to assume that the cryptos will stay on it indefinitely and no one will ever gain access to them.
Online, Web or Hot wallets: These are online services, or online wallets that offer to store the user’s cryptos online with direct access to the internet at any time. In essence, online wallets are online accounts in which users store their funds. The risks are very high, since exchange wallets are routinely being hacked and the cryptos stored therein stolen.
Desktop wallets: Desktop wallets are software programs that can be downloaded and installed on a PC and will only be accessible from the device they were downloaded onto. The risks are the same as with hot wallets and another added inconvenience is that loss of the device or loss of access to it means loss of all cryptos stored on it.
Mobile wallets: Mobile wallets are software programs that can be downloaded onto a mobile device, such as a phone or a tablet. There are wallets for Android and iPhones and all of them bear even greater risks than hot wallets. Since mobile devices are susceptible to theft and a variety of viruses, it is extremely risky to store cryptos on them. Though access to the cryptos without private keys is impossible, unless the user stores them on the device, loss of all cryptos with the mobile device is guaranteed.
Paper wallets: Paper wallets are offline cold storage for cryptocurrencies. This is by far the safest means of storing cryptos, which includes printing the public and private keys on a piece of paper and storing it in a safe place. The keys are printed in the form of QR codes for convenience. With paper wallets, the user has complete control over their funds and the only risk lies in losing the piece of paper with the keys.
Other types of wallets: Apart from the five main types of wallets, there were attempts at creating other types of services, such as atomic wallets using atomic swap technology and even combinations of mobile/hot/cold wallets. Despite limited success, hybrids models of wallets did not become popular.

Main Pros And Cons

When looking at wallets and their main advantages and disadvantages, it is easiest to speak of the division between cold and hot wallets.
When speaking of cold wallets, such as the Trezor Bitcoin wallet and Ledger Nano S or X, the same issue will be observed, and that is the fact that such wallets can be physically lost. Though anyone who ever finds them will never be able to gain access to the stored cryptos without the private keys (unless they are pasted on the device), loss of all cryptos on the device is guaranteed. In addition, cold wallets can be difficult to install and are inconvenient for frequent use.
https://preview.redd.it/ff2dukdx3u341.png?width=1021&format=png&auto=webp&s=f36cdc26b13f33433c5124f5e5a67c0e40f9dbf4
Hot wallets are far more susceptible to risk than their cold counterparts. Though hot storage is much faster and convenient with a wide variety of options from Coinbase to Blockchain.info, the risk of cybercrime runs high. Mobile or desktop storage is also considered to be hot storage and is also risky, if the device is damaged or destroyed.

Bitcoin Problems

Bitcoin, as the firstborn cryptocurrency, was born with a number of defects. One of the main problems of the king of cryptos is the yet unsolved scalability problem. This refers to the limit on the amount of transactions the Bitcoin network can process due to the limited size of and frequency of blocks in the Bitcoin blockchain.
Said problem poses some difficulties to all Bitcoin users and leads to what is known as backlog in the blockchain. The backlog leads to long queues of transactions in the system. With the average transaction time in the Bitcoin blockchain being around 7 transactions per second and the theoretical maximum standing at 27, it is not difficult to understand how long users of the blockchain have to wait for their transactions to pass in times of heightened demand – the time is in the hours and sometimes even days.

Bitcoin Wallets Review

Since Bitcoin is the most popular cryptocurrency on the market, it is logical to judge wallets by their support of the first cryptocurrency. As such, the following will be a brief review of some of the best and most popular Bitcoin wallets on the market.
Online Bitcoin Wallets
Online or web wallets are the most popular ones out there and the best Bitcoin wallet overall is widely considered to be Blockchain.info, which is easily accessible and convenient for everyday use with good security. As an anonymous Bitcoin wallet, Coinbase follows in the lead with its ability to store a multitude of various coins, but with the same security risks that are inherent to all hot wallets.
Android Bitcoin Wallets
Android is the most popular mobile system in the world and plays host to a number of good mobile wallets. The best Android Bitcoin wallet is widely considered to be the Electrum Bitcoin wallet with its excellent reputation, good security and convenience. Though Electrum has some occasional glitches, they are never critical. Another excellent wallet for Android is the Coinomi wallet with its support for a wide variety of cryptos and excellent user support, which even allows for restore options using special phrases. Coinomi has its issues as well, such as occasional exchange glitches, but the many pros outweigh the cons.
Bitcoin Hardware Wallets
The undisputed leaders as the best hardware wallets for Bitcoin are Ledger Nano X and S, Trezor T and Trezor One, and Keepkey. Bitcoin hardware wallets are comparable in their security, accessibility and usability. The difference is mainly in the price, which ranges from $165 for Trzeor T to $59 for the Ledger Nano S model. In fact, the Ledger Bitcoin wallet is often called the king of hardware wallets. The KeepKey Bitcoin wallet is the in the top three hardware wallets as a convenient and stylish device. Though KeepKey supports over 40 assets, it still lacks coin support.
Bitcoin Wallets For iPhone
iPhone’s iOS system is the second most popular for mobile devices in the world and has support for some good wallets as well. The best iOS Bitcoin wallet for iPhone is considered to be the Abra software, which offers credit card support for topping up crypto balances and a good user interface, which is even more oriented at exchanges. The next software is Edge, formerly known as Airbitz. The Edge wallet is best known for high security and good user-friendliness along with multi-currency support.
Bitcoin Wallets For Windows
Bitcoin wallets for PC are very popular and Windows is leading the way with some excellent offers for wallets. Atomic is by far the most advanced and the best option for Windows users as it offers Atomic swaps technology as its basis. The application offers a wide variety of operations and supports over 300 cryptocurrencies. Exodus is the second most popular choice as a desktop only wallet with support for Bitcoin and many other altcoins. Exodus offers its users a good interface and it is free for use.
Bitcoin Wallets For Mac
Since Atomic and Exodus are cross-platform wallets, they can be used on Windows and Mac. Apart from them, there are also Jaxx and Electrum, which can be used on Mac. Jaxx is a multi-currency wallet with support for around 40 cryptos and has a PIN feature. In addition, Jaxx is free for use. Electrum is one of the oldest desktop wallets and is a lightweight wallet that does not require the full blockchain to operate, meaning less storage needed for its operation. The wallet requires a PIN and is essentially a desktop bank with good security and usability. Electrum is also a Bitcoin wallet for iPad, since it can be used on mobile platforms.
Bitcoin Paper Wallet
Since storing cryptos online on exchange or hot wallets or even on devices is risky, it is oftentimes more convenient to use a simple printer to print out the keys and store them. BitAddress offers a convenient and easy to use, step by step guide to creating a paper wallet with the added benefit of sleeping in peace, known that nothing and no one will ever threaten your Bitcoins.
https://preview.redd.it/bh7wi0d64u341.png?width=600&format=png&auto=webp&s=9f7fbd269eea43ac3b8897ad470553ba8b3c730d

Checklist

When embarking on the journey of creating your first wallet, think well of which type to use. The type will depend on the priorities that stand before the user. If security is paramount, then paper or cold storage wallets are the go-to solution. If frequency of use is the name of the day, then hot wallets and their inherent risks are the best way to go.
The most frequent questions related to wallets are how to add money to a Bitcoin wallet and how to set up a Bitcoin wallet. Both questions have no single answer, as each wallet offers its own instructions on how to top up balances and how to set them up. Therefore it is recommended to study all instructions carefully prior to operation.
Either way, there is no silver bullet and some features will have to be sacrificed in deciding how to store cryptocurrencies. The one thing that is constant is the need to store Bitcoins and cryptos and make use of them.

[Call to Action] Make your political contributions in Bitcoin (HowTo)

As the political season heats up I've patiently waited for politicians to install BTCPay servers to allow bitcoin contributions. I'm now realizing that the wait will likely take forever. Then I realized I didn't need to wait. I can send anyone bitcoin anytime I want using an expiring paperwallet. It's all totally legit. Works like this:
  1. Any "gift" to a campaign is an "in-kind" contribution.
  2. Disclosure of personal information is only required for contributions above $200.
  3. Paper wallets can easily be mailed to the campaign headquarters just like checks.
  4. You should keep the private keys and revoke the funds after 90 days (or whatever).
  5. The more paper wallets they receive, the more likely they are to favor bitcoin.
Be aware, your contribution will likely just get stolen by a volunteer, so don't go overboard.
If everyone on this subreddit who plans (or can) vote in the upcoming elections were to give 11,000 SAT to the candidate of their choice, eventually they would have enough to warrant getting an exchange account KYC'ing and going through all the same pains we go through to comply with US AML/KYC law. Possibly provide them a way to walk a mile in our shoes. It will also show these candidates that bitcoin can be used "for good" and isn't just for drug runners.
Although you don't need to fill out a disclosure for small ( < $200 ) contributions, it is still probably a good idea to do so. What you should disclose is Name, Address, Employer, and Occupation. You will also need to sign a statement attesting that you are not contributing on behalf of a labor union, federal contractor, or foreign national (unless a lawful US resident).
As warned above, care should be taken in how much you put on the wallet. It's just like cash, so any volunteer opening mail could swipe it. You also need to be careful to only use a trusted wallet. The bitaddress.org is broadly trusted and a good default choice. I ported it to python in the pypaperwallet module, but most people will likely stick with bitaddress.org as it has had years to build trust and reputation. Obviously you should download the zip and run it locally so as not to trust a web server with private keys.

Basic bitaddress.org HowTo:

  1. Download zip from https://github.com/pointbiz/bitaddress.org/tree/v3.3.0
  2. Download PGP key from https://www.bitaddress.org/ninja_bitaddress.org.txt
  3. Import Ninja's expired key that you downloaded in [2] into GPG.
  4. Verify Ninja's key fingerprint matches the fingerprint in his BitcoinTalk post
  5. Unzip the zip downloaded in [1] and enter that directory
  6. Verify the file bitaddress.org.html.sig using Ninja's expired key
  7. Open the bitaddress.org.html file in Chrome
  8. Print the paper wallet and fund it with a few dollars worth of BTC
  9. Include a letter attesting that you aren't a foreign influencer, with a union, or contractor
  10. Include your Name, Address, Employer and Occupation in the letter and sign it
  11. Make a copy of the wallets private key to void the wallet after 90 days
  12. Mail the wallet and signed letter to the campaign of your choosing
  13. If the funds haven't moved after 90 days, sweep them back to yourself
I've produced the form letters in pypaperwallet, but as I said, it's a new repo from some random redditor. In any case, here's the howto for my module:

Basic pypaperwallet HowTo:

  1. Find latest release at https://github.com/brianddk/pypaperwallet/releases
  2. Expand "Assets" and download the "Source code (tar.gz)" as pypaperwallet.tar.gz.
  3. Download the *.tar.gz.sig file naming it pypaperwallet.tar.gz.sig
  4. Download my key from https://brianddk.github.io/darkweb/brianddk/pub.asc
  5. Import my key using gpg --import pub.asc or whatever you named it.
  6. Verify download with gpg --verify pypaperwallet.tar.gz.sig
  7. Extract the contents of the .zip or .tar.gz file to any directory
  8. From Python 3.7 run pip install pypaperwallet.tar.gz to install dependencies
  9. Review the README.md on how to install the GTK cairo dependency
  10. Modify test.py to your liking and run from python 3.7 to produce the PDFs.
  11. To change wording, modify the contents of template.py
Disclaimer: This mainly pertains to US campaign law, but other countries likely have similar ways for voters to contribute.

  11. Make a copy of the wallets private key to void the wallet after 90 days
  12. Mail the wallet and signed letter to the campaign of your choosing
  13. If the funds haven't moved after 90 days, sweep them back to yourself
I've produced the form letters in pypaperwallet, but as I said, it's a new repo from some random redditor. In any case, here's the howto for my module:

Basic pypaperwallet HowTo:

  1. Find latest release at https://github.com/brianddk/pypaperwallet/releases
  2. Expand "Assets" and download the "Source code (tar.gz)" as pypaperwallet.tar.gz.
  3. Download the *.tar.gz.sig file naming it pypaperwallet.tar.gz.sig
  4. Download my key from https://brianddk.github.io/darkweb/brianddk/pub.asc
  5. Import my key using gpg --import pub.asc or whatever you named it.
  6. Verify download with gpg --verify pypaperwallet.tar.gz.sig
  7. Extract the contents of the .zip or .tar.gz file to any directory
  8. From Python 3.7 run pip install pypaperwallet.tar.gz to install dependencies
  9. Review the README.md on how to install the GTK cairo dependency
  10. Modify test.py to your liking and run from python 3.7 to produce the PDFs.
  11. To change wording, modify the contents of template.py
Disclaimer: This mainly pertains to US campaign law, but other countries likely have similar ways for voters to contribute.

Proof of Keys - A guide

On January 3rd 2019 we'll be taking back control!
This is a guide aimed at newcomers or for anyone who has never had their bitcoin under their own control and wishes to stop relying on exchanges or other people keeping their BTC safe.
While it is in some ways safer to leave the security of your precious BTC up to the huge and more reputable companies in the space, having responsibility over your own money is a key principle in Bitcoin - for very good reason.
Not your keys? Not your bitcoin!
You might also be in a position where someone in your family takes care of your bitcoin for you, off exchange but still out of your control. This is the perfect time to become literate about how to store your BTC yourself and take some pressure off that person. What would happen if they were to pass away? If they have left a guide for you explaining what to do in the event of their death, what happens if someone were to find that guide while they are still alive? Conversely what if there is no guide and the coins are just gone forever?
This guide won't go in to high level solutions like Glacier Protocol, which are so extreme as to (in my opinion) actually do a disservice to the overall goal of getting people to keep their funds under their own control by being so intimidatingly, insanely over the top that people become discouraged. You can break free of the custodial norms of money without going to these levels and still be sleeping comfortably at night.
Finally, we're not trying to bank the unbanked, we're trying to unbank everybody!
With that said, let's go over some of the standard ways you can own bitcoin without third party help.
Hardware Wallets
Firstly, I will suggest a hardware wallet such as trezor or ledger.
There is still time to get one in time for the event should that be your aim, but I'd also like to stress that you should take as long as necessary to know exactly what you are doing before moving any bitcoin.
Should you choose this option, while not the best it is far from the worst and it is the route that I will be recommending in this guide.
When it arrives, check that it hasn't been messed with. Trezor packages come glued together with a seal that must be in tact. There are risks in using hardware wallets, but remember that there is no such thing as perfect security. The wallet will come with a fairly comprehensive guide but there are a few things to say here.
You will be tasked with writing down 24 words as a seed. Here is where the most caution will be needed.
Write down these words on a piece of paper away from anything with an exposed camera such as a cell phone or laptop webcam, away from any prying eyes or windows and even, for the paranoid, without leaving a mark on the surface underneath the paper that you are writing on.
Do not take a photo of these words. And never, ever, ever write them down on anything electronic. Use. Paper.
These words will be used by the hardware wallet to generate the private keys that ultimately need to be used to to tell the bitcoin network where you want the coins at the addresses they correspond to to go. - Sorry mouthful but that's literally the essence of how all this works.
So if you don't have these words and you lose access to your device, or forget the PIN (see further down) then you can't spend your coins - they're gone, or rather, they are stuck at the same address. Forever. Lost bitcoins don't disappear, they just stay at whatever address they were at.
If you do have these words then you can spend the coins. i.e They are yours. However so can anyone else who finds these words (unless you have a secret extra word which I will go into in just a moment).
In bitcoin, knowledge is possession. This is the truest form of intellectual property that has ever existed.
Once you have written down your 24 words, laminate them. (I can't find the link sadly, but I'll never forget the story of a drunk guy on bitcointalk.org taking his paper wallet out of a safe and spilling his drink on them making them unreadable. Don't be that guy).
Laminated? Definitely not exposed to any cameras, people or windows? Good. Find somewhere safe to store them. Ideally an actual fire-proof safe. But first, put it in an evidence bag. This adds additional security (admittedly not much, but IMO it's worth doing).
PIN
Now, once you have followed the instructions on your hardware wallet you should reach the point where it wants a pin. This pin is specific to the device and only protects the device - it does not have anything to do with the bitcoin on the device. It merely protects the device itself, so in the event that it gets stolen, the thief (providing he only has the device, not your 24 words) will not be able to do anything with it. However, if the attacker finds the device and pin, they have your coins they do not need your 24 words. So bare this in mind.
Having the device and the pin means you can spend the bitcoins on this device - even without the 24 words.
Device and nothing else? Useless. Pin and nothing else? Useless. Pin and device even without the 24 words? Control over your bitcoin. Just the 24 words and nothing else? Control over your bitcoin.
....unless:
Secret extra words
You will be given the option to add a 25th word (or even 26th, 27th...you can add as many as you would like.) This is not the same as a pin. This will cause different private keys to be generated. This is becoming standard practice as a thief will look for 24 words, but it changes the scope of any attack they would pull insisting on trying extra words and checking each wallet that gets generated for any bitcoin.
So standard practice is to generate a 24 word wallet, store a small amount of bitcoin in there, and then add an extra word where you store the bulk of your bitcoin. Then your thief will hopefully be satisfied that you aren't hiding a larger stash, or decide to cut their losses. If your 24 words generate an empty wallet that will likely signal to any bitcoin savvy thief that you have extra words up your sleeve.
Rather than describe all this in detail (as each hardware wallet works differently), I will ask the reader to get familiar with their device, set up a few wallets, transfer tiny amounts of bitcoin each time as a test, firstly with just 24 words, then a secret extra word. Get comfortable doing this and make sure you understand what you are doing at every step before moving your actual stash.
If you break/lose your device
Simple, buy a new one and enter your 24 words. Added an extra word? No problem, enter your 25 (or however many) words. It's as simple as that. If lost and not broken, someone who finds it won't be able to do anything if they don't have the pin. Typing wrong pins in after 32 attempts or so, they'll be waiting until the end of the universe until the device lets them try another guess. (That's how trezor works at least - doubling the time required between wrong password attempts each time).
Phone wallets
For those with a smaller amount that don't want to splash out on a hardware wallet, or just want to do this right away, phones are actually pretty decent security wise (I'd use a phone over a laptop as it's easy for laptops to become infected with malware such as Windows 10).
Download a wallet such as GreenAddress and follow the exact same protocol as above. It is exactly the same, except a hardware wallet gains the security of having less functionality than a phone - fewer things can go wrong (but they are more likely to be targeted in transit so....again - no such thing as perfect).
Got an old phone that you don't use any more? It's the perfect use for it. Remember, if it dies on you, you'll still have those 24 words and that's enough to retrieve your coins. (One thing worth mentioning is that secret extra words are not usually possible on phone wallets. They aren't designed for the kind of security that hardware wallets offer).
Additional security
Cutting up your 24 words and placing them in different locations doesn't do a lot to increase security while it does however massively increasing the chances that you yourself will become unable to access your own coins. Don't go overboard and end up losing everything.
Don't make a 500 character pin on your device - as mentioned above a few wrong attempts locks out any thief pretty much until the end of time.
Keeping your 24 words somewhere other than your primary residence might be a good idea, but another country? That's probably taking it too far.
Don't mention bitcoin on facebook. If you were going on about this 5 years ago, everyone there now knows whatever wealth that you had back then is now a few orders of magnitude greater. And that will continue to happen. Don't become a target.
Alternatives
You can use an airgapped laptop - not recommended if you don't know what you're doing.
You can generate a paper wallet using bitaddress.org - no one does this anymore as far as I can tell, and I'm told by core devs that it is a horrible method, even if done offline using a dumb printer.
You can flip a coin 256 times - seriously not recommended unless you are just curious and want to really see under the hood.
That's pretty much it for this guide. I hope people will tear me to shreds in the comments, thus increasing the overall value of this post.
Happy bitcoining!
p.s one thing worth mentioning, "Proof of Keys" is a strange name if you ask me. In Bitcoin, you prove you own coins by signing a message. No one here needs to be doing that. All that January 3rd is about is you, without the aid of any third party, having the full and sole control over your coins.
p.p.s So much of this knowledge comes from Andreas Antonopolous. It has to be said. (when mastering LN btw?)

[Call to Action] Make your political contributions in Bitcoin instead (HowTo)

As the political season heats up I've patiently waited for politicians to install BTCPay servers to allow bitcoin contributions. I'm now realizing that the wait will likely take forever. Then I realized I didn't need to wait. I can send anyone bitcoin anytime I want using an expiring paperwallet. It's all totally legit. Works like this:
  1. Any "gift" to a campaign is an "in-kind" contribution.
  2. Disclosure of personal information is only required for contributions above $200.
  3. Paper wallets can easily be mailed to the campaign headquarters just like checks.
  4. You should keep the private keys and revoke the funds after 90 days (or whatever).
  5. The more paper wallets the receive, the more likely they are to favor bitcoin.
Be aware, your contribution will likely just get stolen by a volunteer, so don't go overboard.
If everyone on this subreddit who plans (or can) vote in the upcoming elections were to give 11,000 SAT to the candidate of their choice, eventually they would have enough to warrant getting a exchange account KYC'ing and going through all the same pains we go through to comply with US AML/KYC law. Possibly provide them a way to walk a mile in our shoes. It will also show these candidates that bitcoin can be sued "for good" and isn't just for drug runners.
Although you don't need to fill out a disclosure for small ( < $200 ) contributions, it is still probably a good idea to do so. What you should disclose is Name, Address, Employer, and Occupation. You will also need to sign a statement attesting that you are not contributing on behalf of a labor union, federal contractor, or foreign national (unless a lawful US resident).
As warned above, care should be taken in how much you put on the wallet. It's just like cash, so any volunteer opening mail could swipe it. You also need to be careful to only use a trusted wallet. The bitaddress.org is broadly trusted and a good default choice. I ported it to python in the pypaperwallet module, but most people will likely stick with bitaddress.org as it has had years to build trust and reputation. Obviously you should download the zip and run it locally so as not to trust a web server with private keys.

Basic bitaddress.org HowTo:

  1. Download zip from https://github.com/pointbiz/bitaddress.org/tree/v3.3.0
  2. Download PGP key from https://www.bitaddress.org/ninja_bitaddress.org.txt
  3. Import Ninja's expired key that you downloaded in [2] into GPG.
  4. Verify Ninja's key fingerprint matches the fingerprint in his BitcoinTalk post
  5. Unzip the zip downloaded in [1] and enter that directory
  6. Verify the file bitaddress.org.html.sig using Ninja's expired key
  7. Open the bitaddress.org.html file in Chrome
  8. Print the paper wallet and fund it with a few dollars worth of BTC
  9. Include a letter attesting that you aren't a foreign influencer, with a union, or contractor
  10. Include your Name, Address, Employer and Occupation in the letter and sign it
  11. Make a copy of the wallets private key to void the wallet after 90 days
  12. Mail the wallet and signed letter to the campaign of your choosing
  13. If the funds haven't moved after 90 days, sweep them back to yourself
I've produced the form letters in pypaperwallet, but as I said, it's a new repo from some random redditor. In any case, here's the howto for my module:

Basic pypaperwallet HowTo:

  1. Find latest release at https://github.com/brianddk/pypaperwallet/releases

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.
https://preview.redd.it/wj8a8xere7i31.jpg?width=720&format=pjpg&auto=webp&s=baa3619e3e5f6cd7e0a0acc008391ffb538e31a0

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.
  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.
  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.
  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.
  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.
  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.
  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.
https://preview.redd.it/g6rslysye7i31.png?width=1024&format=png&auto=webp&s=d55198df56a946a48f58d5086a6632b8978a6286

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.
  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.
  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.
https://preview.redd.it/r2zbmwg2f7i31.png?width=1604&format=png&auto=webp&s=37307ab8591daa165e9d7567e3b790fc07c534ac

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.
  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.
  • WalletGenerator.net
The core of this key-generating wallet is 99% identical to the well-considered bitaddress.org.First of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.

How to keep your wallet in security?

Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
  • Choose a wallet that suits your requirements. All wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.
  • Keep your private key safe. Always make sure that your private key is secure and is stored in a safe place. Moreover, do not share your private keys. No, not with friends. Not even with your parents.
  • Set up 2-factor authentication. Some wallets offer this feature to increase the security of your coins. Do not ignore 2-factor authentication, set it up for extra confidence in protection against theft.
  • Backup, backup, and backup. Nothing protects you better from unforeseen accidents than a good old backup. This way you can keep access to your coins.
  • Store your funds offline. With all the security levels offline wallets are still the most secure ones. Therefore, it is better to keep large amounts of ETH coins only on offline wallets.

Crypto Currency Wallets: 101

So you are ready to buy your first crypto. Wondering how to store your coins? With so many crypto wallets out there it can be very tricky to decide where exactly to keep your digital currency, right? But here we are — an incredibly friendly Stealthex team — to guide and help you realize which type of wallet is just right for you.
Let’s start with some basics. What is a cryptocurrency wallet? In simple terms, it is a kind of a digital equivalent of a bank account that allows you to store, send and receive digital coins. The main feature is that crypto wallets have two important components: a public key and a private key. The public key is a wallet address to which anyone can send you coins. The private key is both a login and a password used to access your currency.
The other feature of crypto wallets is the fact that they don’t actually store currency in any physical form. And when someone sends you crypto, they are essentially signing off ownership of their coins to the address of your wallet. The transaction is confirmed by a record on the blockchain and a change in a balance in your crypto wallet.
There are different classifications of wallets. Let’s go through the main types and features of digital wallets.
1. Classification by type of access to the wallet:
Pros: can help you make transactions in the blink of an eye, user-friendly.
Cons: security risks.
Pros: high level of security.
Cons: not easy to access, low speed.
2. Classification by wallet’s “weight”:
Pros: no risks of transferring personal information over the network.
Cons: risk of getting a virus on your computer, usage inconvenience.
Pros: independence — you can choose which service to use, very easy to handle.
Cons: risk of hackers attack.
3. Classification by the ways of private key storage:
Pros: good security level, convenience, a great choice of wallets, free downloads.
Cons: risk of computer viruses and hacker attacks.
Examples: Exodus, Bitcoin Core.
Pros: simple, very handy, free downloads.
Cons: risk of hacking, losing or damaging your phone which will lead to problems with access to your crypto.
Examples: Xapo, Coinomi.
Pros: easy to use, able to work with multiple cryptocurrencies, high transaction speed.
Cons: security risks, additional expenses such a commission to the service.
Examples: HolyTransaction, Coinbase.
Pros: very high level of security, easy to set up and use.
Cons: expensive ($150–200), inconvenient if you need fast access to your coins.
Examples: KeepKey, Trezor.
Pros: highest level of security.
Cons: risk of destruction or loss of paper that contains wallet info, totally not for beginners.
Example: bitaddress.org.
As you can see there is no such thing as the best crypto wallet. The right wallet for you will be the one that matches your needs and the purpose of your cryptocurrency savings.

Offline Paper Wallet Generator

Hey guys, if this is the wrong subreddit to be posting this in, please let me know. But, I am currently working on a open source application that can generate private keys and public addresses for some of the major cryptocurrencies: Bitcoin, Litecoin, and Ethereum (Monero maybe coming soon). It is a minimalistic application that does nothing but generate private keys and public addresses from a passphrase (similar to how www.bitaddress.org works for brain wallet). I would really like some feedback if anyone can provide it. The source code and application download, as well a further details on how the application works, can be found here https://github.com/andreshyeOfflinePaperWallet. The major drive for this was that I wanted this application to work on a computer that will never touch the internet and never has to touch a JS. Also while being an obscure way to generate private keys with 'non-recoverable mode' (details on git)
My hopes are that this tool can be easy to use and secure, but I am looking for feedback. If anyone is willing to dive into the source code and help find any bugs, I would be more than appreciative. But, I am looking for more general feedback. Is something like this useful? Is the idea of a python base application secure? And any other things that other people can think of that I can not. I know most of you will not like the idea of an unofficial application for this sort of thing, but I find this kind of tool important to have.
Also, I am sorry for the new account. Normally I would only use reddit from Tor, but I wanted to make my identity clear to hopefully build trust with the community.

Paper Wallet without a printer

Hey guys, I want to start getting into bitcoin. I have to be honest though, as a non tech guy, it's a little overwhelming. But from my research, it seems a paper wallet is the safest wallet you can get (as long as you keep your paper in a safe place and don't lose it).

But every tutorial says I should go to bitaddress.org and print it out.

The thing is, I don't have a printer, so can I simply go to bitaddress.org, turn on airplane mode, generate my wallet, and then write down my private key and public key on a piece of paper?

It wouldn't have the QR code things but I can still receive bitcoin and sell bitcoin with just a private and public address written down, right?

And if I'm on airplane mode, I'm safe right? How can I ensure nobody is watching my computer while I generate the paper wallet?

And one more question. At bitcoin.org, it says " To protect your privacy, you should use a new Bitcoin address each time you receive a new payment. " So that means I need to create a new wallet every time I receive bitcoin?

Thanks for the help guys.

All the basic things you need to know about how crypto wallets work

So you are ready to buy your first crypto. Wondering how to store your coins? With so many crypto wallets out there it can be very tricky to decide where exactly to keep your digital currency, right? But here we are — an incredibly friendly StealthEX team — to guide and help you realize which type of wallet is just right for you.
Let’s start with some basics. What is a cryptocurrency wallet? In simple terms, it is a kind of a digital equivalent of a bank account that allows you to store, send and receive digital coins. The main feature is that crypto wallets have two important components: a public key and a private key. The public key is a wallet address to which anyone can send you coins. The private key is both a login and a password used to access your currency.
The other feature of crypto wallets is the fact that they don’t actually store currency in any physical form. And when someone sends you crypto, they are essentially signing off ownership of their coins to the address of your wallet. The transaction is confirmed by a record on the blockchain and a change in a balance in your crypto wallet.
There are different classifications of wallets. Let’s go through the main types and features of digital wallets.
1. Classification by type of access to the wallet:
Pros: can help you make transactions in the blink of an eye, user-friendly.
Cons: security risks.
Pros: high level of security.
Cons: not easy to access, low speed.
2. Classification by wallet’s “weight”:
Pros: no risks of transferring personal information over the network.
Cons: risk of getting a virus on your computer, usage inconvenience.
Pros: independence — you can choose which service to use, very easy to handle.
Cons: risk of hackers attack.
3. Classification by the ways of private key storage:
Pros: good security level, convenience, a great choice of wallets, free downloads.
Cons: risk of computer viruses and hacker attacks.
Examples: Exodus, Bitcoin Core.
Pros: simple, very handy, free downloads.
Cons: risk of hacking, losing or damaging your phone which will lead to problems with access to your crypto.
Examples: Xapo, Coinomi.
Pros: easy to use, able to work with multiple cryptocurrencies, high transaction speed.
Cons: security risks, additional expenses such a commission to the service.
Examples: HolyTransaction, Coinbase.
Pros: very high level of security, easy to set up and use.
Cons: expensive ($150–200), inconvenient if you need fast access to your coins.
Examples: KeepKey, Trezor.
Pros: highest level of security.
Cons: risk of destruction or loss of paper that contains wallet info, totally not for beginners.
Example: bitaddress.org.
As you can see there is no such thing as the best crypto wallet. The right wallet for you will be the one that matches your needs and the purpose of your cryptocurrency savings.
