Frequently Asked Questions – Bitcoin Electrum

When buying bitcoins with USD (example an ATM) do you use the address that’s made on electrum Or do you make a separate address then transfer it to to electrum on TAILS

Title says it all. I’m a bit confused with all this dark net buying stuff because I would like to buy coins. Should I make a separate address when buying the coins then transfer it to an address made on Tails, or should I use the address from Tails directly. Also I don’t understand the concept of adding funds from my wallet to a market account. Thanks if someone can explain this easier.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:

Everyday info sec, hardcore info sec, and DNMs

Edit: Currently writing a new version of this, dont know when it will be done.
Edit: Since first post I have updated a few sections with additional information.
I recommend reading it all even if it is very long, I might have placed some relevant info in different sections while thinking about what else needed to be added, plenty of steps remains mostly the same except when I comment directly on it. It is not necessary to do 100% security all the time, unless you absolutely need it, combining some high and some lower security ideas for a balance of security and convenience is useful.
I will base this mostly on Windows, Linux users probably know this, and I have no idea how apple machines work (tho many things in here are still relevant for other operating systems, as they are just general tips)
Disclaimer: There are certainly other steps that can make you more anonymous or safer, however I think for most people this will surfice. Any software I recommend should be independently verified for security, and examples of software are not to be taken as endorsements. I simply use examples and give recommendations when I believe it necessary, or helpful.
I will not really differentiate between anonymity and security, they are often the same thing. As such the word security can mean either more anonymous, less vulnerable, or both.
--------
Everyday Simple Info Sec:
-There could be a hidden administrator user on your PC, make sure to change its password
(Snapchat msgs, reddit dms, discord msgs, are just a few examples of msgs that are never encrypted)
-Any info even send in encrypted msgs (and obviously non encrypted) should still be kept with possible deniability, don't say "I'm gonna do MDMA", say "I'm going out with molly."
-DO NOT STORE ANY PASSWORDS ON GOOGLE, IF GOOGLE LOGIN IS AUTHENTICATED IT WILL AUTFILL ALL PASSWORDS IT HAS SAVED (same with other similar services) (This means if you are logged in to chrome and someone has access to your machine, they can auto fill passwords without entering a single password)
-use a rememberable passphrase, especially for your master key ring aka password manager A long sentence that is memorable makes an okay password (decent example,: "I met my wife at Little Ceasers for the first time on 07/09/20" better even if it's just something you know, if its impersonal, and if you can add special characters or numbers that you won't forget) (A better example for a passphrase is: "There is 0nly 0ne letter that d0esn’t appear in any U.S. state nameQ")
-Purge your internet activity frequently, there's a reason why I only have one post, and a few comments appearing in my account, but thousands of kama. Exposing information needlessly is not good.
-Never post private information publicly, and if you do, do it vaguely as possible. (Example: Not "I'm 15", say "I'm a teenager") Do not post any vital information ever, no birthdays, mother's maiden name, age, or anything you have ever seen in a security question. Never post your current activities while they are ongoing. You going on a vacation? Don't announce it to the world, taking picture there? Post them when you are home.
-Rethink how you do security questions. Many answers to security questions can be found in your internet history. One could use the first word of the security question as an answer, or a different sceme that will mean you always remember it. (Security question need to go, the amount of personal info an average person puts on the internet makes it easy to attack anything using security question)
-------_
High level crimimal information security:
The motto here is, "All the Security, All the Time" As one fuck up can end with you leaving a lick of traceability, and you could be fucked.
Pre Note: All of your software should always be up to date. Also even perfect info sec does not guarantee you are completely safe, a new zero day (exploit) can still fuck you, but good info security makes you significantly safer, by eliminating as many attacks as possible.
-Get a new device (or make a already owned device seem like you never owned it, do this only if you know how to, there's a lot of stuff that goes into that, like changing your mac adress etc) buy with cash, and your face covered, preferably far away from where you live. (Do I need to specify to not bring your phone or anything else that tracks your location to anywhere you want to go anonymously?) (Be aware that even hardware can have vulnerabilities, many cpus have known vulnerabilities, I can't list them all, do some research before buying)
-If you know how to use Tails (A linux distro designed for Info sec) use that, preferably on a USB. (Or learn how to use tails, its better, but complicated) Otherwise a clean copy of windows (make sure its not in any way associated with you) can do the job too, tho not as well. (Using a VM might give extra security, since VMs usually erase all data and RAM they were using on shutdown)
-Get a non tracking VPN, Enable the kill switch (a setting that disables all traffic that doesn't go through the VPN) (change your firewall settings to only allow the traffic from the VPN, windows guide (Change settings so only traffic from the tor application is send) Edit: (Due to complaints: do not use vpn over tor, use tor over vpn. tor over vpn has no notable downside, if the VPN logs it makes no difference, your ISP will always log anyways, and vpns remove other attack vectors and also provide backup security should tor fail. Again even if the VPN tracks you only change the people doing the tracking, but now you are further removed making it more anonymous and also with less vulnerabilities)
-rember privacy settings, cookie cleaner, and antivirus, password (There could be a hidden administrator user on your PC, make sure to change its password)
-Always use the device on a non admin account
-Ideally use this device only on networks that are not connected with you. Such as public networks (try to never use the same public networks twice, move around) (a home network should be fine now, as it should never be exposed, but more security is always better) (Its just a conveniences vs security trade)
-Never use accounts that have been exposed to lower security on higher security machines
-your browser is now TOR (or your preferred security focused browser, if you dont plan on using onion ) Make sure you get the standalone version of tor not the addon build (the standalone is safer, because there are less settings and options to tweak)
-Change your tor settings, to safest mode, enable a bridge (to my knowledge there's no difference in security between the build in bridges in tor), enable automatic updates, set duckduckgo onion as your primary browser. Set dark.fail onion page as your home page. (Or your preferred privacy search engine and onion directory)
-------_
How to use dark net markets (DNMs)
If you finished your High Security setup, we can dive right in. Otherwise go do that. This is where all that is essential.
Quick info on Tor, and onion sites. There is no search engine. It's all based of directories and addresses you are given by others. Tor will likely not be very quick, it has to pass through multiple networks to get to the destination. DNMs sometimes exit scam, an exit scam is when a market shuts down completely and takes all the money, this is a risk when using DNMs, it's not too common but happens maybe 0-4 times a year. The admins of thoese servers need to get out at some point, before they get jailed, so they exit the game, and scam everyone out of their money.
-A very useful onion directory is dark.fail it has a lot of links, for all kinds of stuff. News, email, DNMs, Psychonautwiki (harm reduction website), forums etc. (Other directories also exist)
-Pick a market, preferably one that handles secure connection server side instead of requiring you to establish the secure connection. Then create an account. Your account once created should include an entry box in your profile for a pgp key, post your PUBLIC key in there. (Verify the link is not a scam, most markets should provide a pgp signature)
-Next is currency setup. All major cryptocurrency exchangers can be used, I can recommend coin base but there could be better ones out there. Unless you find a small non U.S., exchange, they will always ask for your identity. So unless you can find a trustworthy exchange that doesn't ID, you will need to give it to them. (Side note, all major crypto exchangers report to the IRS, if the IRS asks you if you bought cryptocurrency and you bought while having IDed yourself SAY YES, DO NOT COMMIT TAX FRAUD WHEN THEY KNOW YOU DID)
-Transfer (monero you can send directly, btc you should scramble) to your wallet. There are two options a cold wallet (physical) or a software wallet. Software wallets usually dont cost anything so I recommend them, even if often less safe. Electrum is easy to use, and pretty safe. You can also do your own research and find a wallet that fits your needs.
-now you are ready to buy, only buy using escrow (it means the money is held by the market as a middle man until the product is delivered, they will also handle any issues like wrong quantity, cuts, etc), judge the reviews for a product, and if available look at the history of the vendor, until you find a product from a vendor you trust. (I recommend to buy within your country as much as possible, so it doesn't go through customs, it's very rare that something is found, but it can happen)
-now you get to buy, depending on market, you either have cryptocurrency stored in their wallets (not recommend, you will lose it in an exit scam) or you can send it every order. When you send your delivery adress (or the one you want it to go to) encrypt the adress using the sellers public key. Make sure the adress is correct.
-wait for the product, make sure to extend the escrow until the product arrives, if you can't extend it anymore dispute the order, and a moderator will step in
-test the product, use it, and leave a review. PLEASE LEAVE A REVIEW, DNMs only work because of reviews.
Edit: Didn't imagine I would write over 15000 words. Oh well, it was fun. Hope it helps, if you have any questions feel free to ask.
No idea how long this will stay up, I might purge it in 7 days, or never.

How to perform strong verification of multisig receive addresses and limit trust in software wallets?

Example scenario: you've set up a 2-of-3 multisig watch only wallet in Electrum or some other desktop wallet, and you use it to generate receive addresses. How do you protect yourself from maliciously generated receive addresses for this wallet, in the case that the desktop software is compromised? How do you validate that the receive addresses are correct and not an attacker's receive address? how do you limit trust of the desktop software wallet?
With typical single-sig P2PKH and P2WPKH the receive addresses can be independently verified to belong to a known xpub key using any bitcoin software library and a small script. Hardware wallets can also be used to generate or verify receive addresses so the software wallet doesn't not need to be trusted. Some hardware wallets also verify the change address for a given transaction also belongs to the xpub key in question.
So how do you do this kind of verification for multisig wallets? Or are people not verifying and instead just trusting that their software wallet of choice is not compromised? I haven't found examples online to do this. It appears that in the Coldcard multisig set up process for a 2-of-3 setup, each device is aware of the other 2 xpubs, so presumably it has the information to perform this kind of verification, but I don't know if it actually does that verification.

The power of "import electrum" as a python bitcoin scripting engine

I've been a big fan of Electrum as a wallet for a while now. Traditionally, when I wanted to do bitcoin scripting I would use either trezorlib, pycoin, or bitcoinlib. But recently I was digging a bit deeper into the Electrum source and found it to be one of the simpler python libraries to use to craft bitcoin transactions.
One of the nicer things about Electrum as a scripting engine is that you can drop the standalone app or AppImage on a system and run your scripts directly through the console. This makes doing things on Tails or other locked down systems much easier. To run one one of your scripts (without the event loop) simply type (assuming you correct the file path):
with open(r"myscript.py", 'r') as s: exec(s.read())
Obviously only do this with scripts you've personally authored. Never run random code on your machine especially when wallet private keys are in play.
There are already some great scripting examples in the electrum\scripts folder, but most of these use the event loop which brings in a lot of overhead. I found simple TXN processing can easily be done without spawning an full electrum thread. I'd be happy to PR the samples if there is any interest in this style from the maintainers.
Here's two examples I put together that craft a BIP65 spending transaction. It turned out to be much simpler than I imagined. I did it both in bitcoinlib and electrum. The structure is very similar and should hopefully be easier to follow. Feel free to start a PythonRoastMe on it.
Two things of note. I had to disable R-value grinding (nuked while loop) so that I had parity with bitcoinlib, which hasn't rolled it out yet. This is why the TXIDs differ. I also had to override the the PartialTransaction.get_preimage_script method since it makes certain multisig assumptions that don't apply to generic scripting.
Reference: * Electrum script to spend an OP_HODL P2WSH address (txid 3a461e6...78de2b6) * Electrum script to spend an OP_HODL P2SH address (txid a8110bb...3dadc93) * BitcoinLib script to spend an OP_HODL P2WSH address (txid 3a461e6...78de2b6) * BitcoinLib script to spend an OP_HODL P2SH address (txid a8110bb...3dadc93) * TXID 3a461e6...78de2b6 (P2WSH) on the blockchain * TXID a8110bb...3dadc93 (P2SH) on the blockchain * BIP-0065: OP_CHECKLOCKTIMEVERIFY (aka OP_HODL) * BIP-0141: P2WSH symantics * BIP-0016: P2SH symantics

What is Bitcoin Cash and some exchanges to try out!

Bitcoin Cash (BCH) came about in August 2017 after a hard fork and a split in the Bitcoin blockchain. Bitcoin Cash is a direct result of the constant debates and many opinions about the future of Bitcoin’s scalability and mass adoption.

Bitcoin vs. Bitcoin Cash

Bitcoin’s blockchain has grown exponentially in recent times. This means that many more users are using the cryptocurrency, which is slowing down the network.
The limited Bitcoin block size of 1 MB means that blocks are filling up quickly, resulting in a long queue of unconfirmed transactions. As a result, at peak times, transactions have become slow and expensive.
Bitcoin cash, on the other hand, was initially created with an 8MB block, which was later on increased in size to 32MB. This change allows for more transactions to be processed in each block mined.
Many see this as a step forward in terms of how best to scale the network.
Bitcoin Cash opposers remain adamant that it’s simply a short-term fix that doesn’t solve the problem in the long run. Also, they claim there’s no implementation of ideas such as Segwit to help effectively break transactions down into smaller, more manageable pieces.
Bitcoin Cash (BCH), Sometimes referred to as Bcash, is a fork of Bitcoin (BTC). When a fork occurs on a Blockchain, the currency is basically duplicated.
This means that anyone with Bitcoins in his possession at the time the fork occurred, got credited with the same amount of Bitcoin Cash.

Buying Bitcoin Cash in 3 Simple Steps

Step 1: Get a Bitcoin Cash Wallet

Before you can buy Bitcoin Cash, you’ll need a Bitcoin Cash wallet to store it in. Hardware wallets that support Bitcoin Cash include industry leaders Ledger and TREZOR.
Both Ledger and TREZOR provide functions for you to use Bitcoin Cash as you would any other cryptocurrency. Both have also introduced the ability to claim your funds if you already owned Bitcoin at the time of the Bitcoin Cash hard fork.
Additionally, there are a variety of software wallets you can use to store Bitcoin Cash as well.
Exodus provides a great user experience with a seamless coin exchange service known as Shapeshift built in.
Edge is a mobile wallet for iOS and Android that supports multiple cryptocurrencies including Bitcoin Cash. It also has a variety of features allowing you to buy cryptocurrencies and exchange them from within the app.
Electron Cash is a clone of the awesome Electrum wallet for Bitcoin. If you’re used to Electrum, then you’ll have no problem jumping on board with its sister technology.
Other wallets that support BCH include Keepkey, BTC.com, Bitpay, and Coinomi. You can view all available wallets on the official Bitcoin Cash website.
Once you have your wallet, you will need your Bitcoin Cash address. It’s a long string of letters and numbers that start with either a “1” or a “3” — similar to normal Bitcoin addresses.
Since many people got confused and started sending Bitcoins to Bitcoin Cash wallets and vice versa, a new format was invented for Bitcoin Cash. The format, called “Cash Address” is 42 characters long and starts with a “p” or a “q”. Here’s an example:
qpm2qsznhks23z7629mms6s4cwef74vcwvy22gdx6a
Keep in mind that Cash Addresses are just a representation of original Bitcoin Cash addresses. This means that the same address can be represented in two different ways (normal format or Cash Address format).
Not all wallets support Cash address format.

Step 2: Find a Bitcoin Cash Exchange

Most Bitcoin exchanges will also allow you to buy Bitcoin Cash, here are top ones around.
Buy Bitcoin Cash Through eToro
eToro allows users from around the world to buy and sell Bitcoin Cash with a variety of payment methods.
eToro is more aimed towards investing in BCH for making a profit in fiat currency (i.e. Dollars, Euros, etc.) rather than actually using it. That being said, eToro does give you access to your coins and allows you to send coins from eToro to other people.
If you use eToro for investment only, you don’t actually need a Bitcoin Cash wallet as you won’t be withdrawing the coins.
*75% of retail investor accounts lose money when trading CFDs with this provider. You should consider whether you can afford to take the high risk of losing your money. CFDs are not offered to US users. Cryptoassets are highly volatile unregulated investment products. No EU investor protection.
Buy Bitcoin Cash Through Coinmama
Coinmama, one of the oldest exchanges around, allows you to buy Bitcoin Cash with a credit card, debit card or SEPA transfer. Coinmama accepts users from almost all countries around the world.
Buy Bitcoin Cash Through CEX.io
CEX.IO, based in London, is a trusted, experienced name in the industry, having been around since 2013. You can choose from a selection of cryptocurrencies on the site, including Bitcoin Cash.
The exchange has a brokerage service (easier to use, more expensive) and a trading platform (cheaper but more complex).CEX accepts credit cards, debit cards, wire transfers and SEPA.
Buy Bitcoin Cash Through Coinbase
Coinbase is a reputable Bitcoin exchange that supplies a variety of other services including a wallet, a trading platform (Coinbase Pro) and a Bitcoin debit card.
If you’re a beginner, it’s probably best to use the brokerage service which is a bit more expensive, but easier to use. Advanced users can use Coinbase Pro to buy Bitcoin Cash with lower fees.
Coinbase accepts debit cards and wire transfers.
Buy Bitcoin Cash Through Bitstamp
Bitstamp, the oldest exchange around, supports the trading of BCH to Bitcoin and direct purchases with US dollars or Euros. There’s also an option to buy Bitcoin Cash with your credit card at a higher price.
If you know your way around Bitcoin trading platforms it’s best to use that service and not the credit card service since you’ll save substantially on fees.
Other options to purchase Bitcoin Cash include Bitfinex, Cryptmixer, Kraken, Poloniex, HitBTC, and more (you can view all available exchanges on Bitcoin Cash’s website).

Step 3: Transfer the BCH to your wallet

As usual, I recommend that you never leave money on an exchange.
Once you’ve finished buying your Bitcoin Cash, move it to your own wallet (the one you chose in step 1). You can then follow the status of your transaction using a Bitcoin Cash block explorer.
Once you receive three confirmations for your Bitcoin Cash, you can safely say you’ve completed the process.

Conclusion

It’s apparent that Bitcoin Cash has still not gained full acceptance by large parts of the cryptocurrency community. It still sits firmly in second place to its older brother in terms of both price and usage.
Bitcoin Cash has the advantage of being the first major split that has garnered acceptance. Most forks after it didn’t receive nearly enough attention from the community or the media.
However, with internal conflicts inside its founding team and accelerated Bitcoin development for scalability solutions, I’m not sure if there’s an actual use case for Bitcoin Cash other than price speculation.

Storing your coins safely while not risking loss of keys

This was originally an answer to a question that was asked here, but OP deleted their post.
This might help some newbies (especially the multisig edit at the end), so I want to make sure it's still accessible here.
The original question was whether the Electrum wallet stores a Trezor's private key when using a passphrase.
OP noticed that their Trezor wouldn't connect to their Electrum wallet when entering a different passphrase than they used when creating the wallet. Thus, OP (likely) assumed that the wallet stored the private key, as it somehow knew that a different private key was now used.
Here is my original answer (with some modifications):
IMPORTANT: I'm assuming here that you connected your Trezor by choosing the "hardware wallet" option in Electrum, rather than giving Electrum your 12/24 seed words.
TL;DR: No, your coins are safe :)
I'm assuming by passphrase) you mean the 25th (or 13th) word. When you have this feature enabled, a private key gets generated every time you enter a passphrase. When you enter the same passphrase you used to create the wallet, the wallet with your funds shows up.
Whenever you enter something different, a different private key is generated on your Trezor. This allows you to have multiple different wallets, for example by choosing the passphrases "First Wallet", "Second Wallet", "Third Wallet", or a secret wallet with a secret passphrase.
So whenever you enter a new passphrase when connecting your Trezor to Electrum, the Trezor will send a new public key to Electrum. Electrum will then derive addresses from this public key and check those for balances. It won't find any, as you used a new passphrase.
EDIT: I just realized that you said your wallet doesn't connect to Electrum when you use a different passphrase. This is simply because Electrum doesn't receive the correct public key from the Trezor and therefore Electrum thinks it's a different wallet (which it is).
When you enter the passphrase you used during creation of your wallet, the Trezor will send your actual public key to Electrum, which will then find addresses with balances, which it will show to you. EDIT (to clarify): Connecting your Trezor after creating the wallet is only necessary to send funds or verify addresses, as the public key is already stored in the wallet.dat.
The only thing Electrum actually stores is the public key, which can only be used to look at your Bitcoin, not to move them. You might want to keep this public key a secret as well though, since it links all your funds to you. This is what Electrum stores in the wallet.dat file, which you can just encrypt by choosing a password for it.
Well done using a passphrase by the way! Should someone get their hands on your Trezor, a sophisticated attacker can get the secret key off the device in 15 minutes. Using a passphrase makes this attack almost useless, as the both secret key AND the passphrase are needed to move your funds, and the passphrase is not stored on the device. A passphrase also allows you to hide funds from potential robbers that force you to unlock your wallet.
You can do this by activating the passphrase feature and sending your funds to a wallet with a secret passphrase (do NOT lose this, as losing your passphrase renders your funds inaccessible). Afterwards, you can safely deactivate the passphrase feature, so the device doesn't even ask for one should you get robbed. Simply reactivate it when you need to access your funds.
EDIT: Should you be worried that you might forget your passphrase, you should look into multisig wallets. Depending on how you set this up, you can make it more secure against theft and less likely for you to lose access to your funds.
Say for example you get four wallets: two hardware wallets, a well-protected (airgapped) laptop with Electrum, and a secure mobile wallet that allows for multisig (like Fully Noded).
You can then create a 2-of-4 multisig wallet that requires you to sign transactions with any two of these four wallets.
The increase in security comes from the fact that an attacker now needs full access to two of your devices (or their stored private keys) at once.
At the same time, the fact that you yourself now also need access to only half of your devices means that in the event of a total loss of one (or even two) of them, you can still move your funds to a new wallet.
As long as you do regular checks (e.g. first day of each month), ensuring that you still have access to all your devices' stored private keys, you can always catch a loss of keys and fix this without losing funds (by creating a new multisig wallet and sending the funds there).
This allows you to use a passphrase on your wallets without storing it anywhere physically or digitally. This would usually be very risky, as forgetting the passphrase would lead to a loss of funds, but this risk is now close to eliminated.
(The following part was not in the original answer)
Some IMPORTANT general secruity tips:
  1. Consider including trusted friends and/or family members as co-signers for a multisig wallet. This ensures that it's not even possible for you alone to hand over funds to an attacker. Depending on your level of trust, you might want to make sure that your co-signers can't collaborate to steal your funds (if you include 3 people, create at least a 4-of-n multisig). You could also deliberately make it possible for all or even just some of your co-signers to move your funds (3 co-signers, 3(or less)-of-n multisig) to make sure your funds aren't lost should pass away unexpectedly.
  2. Consider running your own full node and Electrum server (also check the alternatives), which you connect your Electrum wallet to. This ensures that you don't send your public key to anyone else. If someone knows your public key, they know how much BTC you own, making you a potential target.
  3. Always encrypt your wallet.dat (or whatever you called your wallet file), even if it's a watch-only wallet. This protects your public key (see 1. for why you want that).
  4. Create watch-only wallets: Use an airgapped) device to create a wallet with Electrum (make sure to back up the seed phrase) and export the public key. Then create a new watch-only wallet on another device (like your everyday laptop) with that public key to be able to check your funds. To create the initial wallet, you can also use any other hard- or software wallet that allows you to export the master public key.
  5. Hide, or (when using a hardware wallet with a passphrase) even delete your watch-only wallets. Hiding your funds makes you less of a target. When using a hardware wallet, recreating the watch-only wallet is fast and simple, so you don't need to store it if you don't want to check your funds every day. Note that this approach doesn't help much when you don't use a passphrase, as an attacker will obviously check the passphrase-less wallet no matter what.
  6. Keep some funds on your hardware wallet(s). If an attackers sees funds on the wallet(s), they might not force you to enter a passphrase or ask if you have any multisig wallets (lying under pressure is hard).
  7. Hide all your wallets in different places. If someone sees that you have multiple wallets lying around, they might realize you have a multisig wallet.
  8. Don't risk a robber getting (for example) two keys to your 2-of-4 multisig wallet and then racing them to move your funds with the other two keys when they leave. They're gonna come back and be pissed. If it comes to this, you need protection until the robber is caught. STAY SAFE!
  9. The easiest way to solve a problem is to never have it. Don't make yourself a target. If nobody even suspects that you have a multisig (or any wallet at all), they're probably not gonna look for it.
Please correct any mistakes you find and I will edit my post. I will also gladly add more tips to the list. I will of course credit anyone who helps.
Tip for devs who want something cool and important to work on: Make the creation and usage of multisig wallets as noob-friendly as possible. If someone expresses worries about losing access to their funds by forgetting the seed phrase, wallet pin, etc. (someone in my family actually brought this up to me), multisig wallets are the perfect solution as they add redundancy.

Guide for novice crypto investors

Bitcoin is a decentralized system, any user of which could control the movement of their own funds. You can use the currency to make transactions, pay for purchases, receive transfers, and exchange it for cash. For transactions, a special address is used, encrypted with a 16-character key. The buyer decodes the code to transfer bitcoins to the specified address.

Bitcoin Mining

Mining is a process that ensures the security of the BTC system, which adds new blocks to the blockchain in chronological order (new transactions). Blocks are added when the codes are decrypted, the transaction is completed, and bitcoins are transferred or exchanged.
The main cryptocurrency is generated by miners using software that solves cryptographic problems. The reward for a new block is agreed by all network participants, but usually amounts to 12.5 bitcoins. Part of the user fees for transactions also goes to reward the miners. Cryptographic tasks become more complex every year to prevent inflation (mining complexity).

Features of the transaction

  1. Anonymity. The address that Bitcoin is sent to consists of 30 characters. You can track the flow of transactions, but the address is not always associated with a real person.
  2. Security. The balance of bitcoins is fixed in a cryptographic system with a public key. Only the owner of a private key can send cryptocurrency to other addresses.
  3. Unable to cancel. It is no longer possible to cancel the transaction after the transaction has been completed.
  4. Deregulation. Everyone can use cryptocurrency.
  5. Coverage and speed. Information about the transaction is transmitted incredibly quickly, and confirmation is received within a few minutes. No one knows the buyer’s physical location.

Where to buy Bitcoin?

There are Deposit systems that use crypto-exchanges. So, to buy Bitcoin, you will first need to top up your balance, buy the digital currency itself, and then withdraw it to your Bitcoin wallet, paying a Commission for withdrawing coins. The cheapest method of buying is buying on the stock exchange. The exchange rate is as close as possible to the market rate.

BTC rate

The current exchange rate of the coin is calculated based on the average price on the largest currency exchanges. For example, you can track the exchange rate on our Bitniex exchange. The Bitcoin exchange rate is constantly changing, during the day it can change by 10% in one direction or another.

The choice of crypto-currency wallet

A cryptocurrency wallet is a place where digital currency will be stored. The most secure method of storage is using paper or electronic wallets.

TOP secure cryptocurrency wallets

These wallets are one of the most secure crypto wallets in the world:

Generating an indexed btc address from an xpub key

An xpub key can generate a sequence of bitcoin addresses.
In this example ,1EfgV2Hr5CDjXPavHDpDMjmU33BA2veHy6 is the first, 12iNxzdF6KFZ14UyRTYCRuptxkKSSVHzqF is the second and so on and so forth.
With any Bitcoin API implementation is possible to easily generate a btc address from any xpub, where the xpub key is the input and the index is a parameter defining the position of the btc address in the derivation tree.
An example using the C# NBitcoin API:
BitcoinExtPubKey xpub = new BitcoinExtPubKey("yourxpub", Network.Main);
bitcoinAddress = xpub.Derive(0).Derive(btcindex).ScriptPubKey.GetDestinationAddress(Network.Main);
In this example, if the variable btcindex==0 and the xpub is the one from the example, the generated address is the first, namely: 1EfgV2Hr5CDjXPavHDpDMjmU33BA2veHy6 .
If btcindex==1, the second and so on and so forth.
Now, let's suppose we generate a btc address with index like 9999999 and send money to it, moreover only the first btc address has a positive amount, every btc address in the range between the first and the 9999999th has been never used before.
What may happen if we use a LedgeTrezor or a wallet like Electrum? As far as I know they need to scan the blockchain to find the addresses, but one thing is to scan one-hundred, another thing is scanning a billion!
Will that btc address even counted? If yes, will it be done in a reasoneable time?

How to Store Your Bitcoin

Before holding any bitcoin, you need somewhere to store it. Just like in the physical world, you store your bitcoin in a wallet.
Similar to a bank account number, your wallet comes with a wallet address that shows up in a ledger search and is shared with others so you can make transactions. This address, which is a shorter, more usable version of your public key, consists of between 26 and 35 random alphanumeric characters, something like 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa. Keep in mind that every letter and number in that address is important. Before sending any bitcoin to your wallet, double-check the entire address, character by character.
Also tied to your wallet address is one or more private keys, which as the name suggests should not be shared with anyone. Keys are used to verify you own the aforementioned public key, and to sign off on transactions. Some wallets create a secure seed phrase, a set of words that will allow you to unlock your wallet if you lose your keys. Print this phrase out and keep it in a safe place.
The unfortunate truth is your bitcoin wallet is akin to your physical wallet. If you lose the private keys to your wallet, you’re most likely going to lose the currency in it forever.
Your wallet generates a master file where your public and private keys are stored. This file should be backed up in case the original file is lost or damaged. Otherwise, you risk losing access to your funds.
You can store your private keys on your computer, mobile device, on a physical storage gadget or even on a piece of paper. It’s crucial that you keep your private keys safe by generating backups both online and offline.
Remember: Your wallet does not reside on any single device. The wallet itself resides on the Bitcoin blockchain, just as your banking app doesn’t truly “hold” the cash in your checking account.
While wallet apps work well and are relatively safe, the safest option is a hardware wallet you keep offline, in a secure place. The most popular hardware wallets use special layers of security to ensure your keys are not stolen and your bitcoin is safe. But, once again, if you lose the hardware wallet your bitcoins are gone unless you have kept reliable backups of the keys.
The least-secure option is an online wallet, i.e. storing your bitcoin in an exchange. This is because the keys are held by a third party. For many, the online exchange wallets are the easiest to set up and use, presenting an all-too-familiar choice: convenience versus safety.
Many serious bitcoin investors use a hybrid approach: They hold a core, long-term amount of bitcoin offline in so-called “cold storage,” while keeping a spending balance in a mobile account.
Depending on your bitcoin strategy and willingness to get technical, here are the different types of bitcoin wallets available. Bitcoin.org has a helper that will show you which wallet to choose.
Cloud wallets exist online and the keys are usually stored in a distant server run by a third party. Cloud-based wallets tend to have a more user-friendly interface but you will be trusting a third party with your private keys, which makes your funds more susceptible to theft. Some examples of this wallet type are Coinbase, Blockchain and Lumi Wallet. Most cryptocurrencies, including bitcoin, have their own native wallets. Some offer additional security features such as offline storage (Coinbase and Xapo).
With your private keys stored on a server, you have to trust the host’s security measures and also trust the host won’t disappear with your money or close down and deny you access.
Software wallets can be installed directly on your computer, giving you private control of your keys. Most have relatively easy configuration and are free. The disadvantage is you are in charge of securing your keys. Software wallets also require greater security precautions. If your computer is hacked or stolen, the thief can get a copy of your wallet and your bitcoin.
While you can download the original software Bitcoin Core protocol (which stores a ledger of all transactions since 2009 and takes up a lot of space), most wallets in use today are “light” wallets, or SPV (Simplified Payment Verification) wallets, which do not download the entire ledger but sync to it.
Electrum is a well-known SPV desktop bitcoin wallet that also offers “cold storage” (a totally offline option for additional security). Exodus can track multiple assets with a sophisticated user interface. Some (such as Jaxx Liberty) can hold a wide range of digital assets, and some (such as Copay) offer the possibility of shared accounts.
Before downloading any app, please confirm you are downloading a legitimate copy of a real wallet. Some shady programmers create clones of various crypto websites and offer downloads for free, leading to the possibility of a hack.
Mobile wallets are available as apps for your smartphone, especially useful if you want to pay for something in bitcoin in a shop or if you want to buy, sell or send while on the move. All of the online wallets and most of the desktop ones mentioned above have mobile versions, while others – such as Abra, Edge and Bread – were created with mobile in mind. Remember, many online wallets will store your keys on the phone itself, leading to the possibility of losing your bitcoin if you lose your phone. Always keep a backup of your keys on a different device and print out your seed phrase.
Hardware wallets are small devices that connect to the web only to enact bitcoin transactions. They are more secure because they are generally offline and therefore not hackable. They can be stolen or lost, however, along with the bitcoins that belong to the stored private keys, so it’s recommended that you backup your keys. Some large investors keep their hardware wallets in secure locations such as bank vaults. Trezor, Keepkey and Ledger are notable examples.
Paper wallets are perhaps the simplest of all the wallets. Paper wallets are pieces of paper that contain the private and public keys of a bitcoin address. Ideal for the long-term storage of bitcoin (away from fire and water, of course) or for the giving of bitcoin as a gift, these wallets are more secure in that they’re not connected to a network. They are, however, easier to lose.
With services such as WalletGenerator, you can easily create a new address and print the wallet on your printer. When you’re ready to top up your paper wallet you simply send some bitcoin to that address and then store it safely. Whatever option you go for, be sure to back up everything and only tell your nearest and dearest where your backups are stored.

Wallets with Coin Control and Trezor support?

I know that Electrum has Coin Control but I don't like the fact that you have to connect to a server that I don't trust like I would trust a server run by Trezor or Blockstream for example. What I mean is that the server will know all my transaction history, addresses, etc, so at least I need to trust the server. I know of Electrum personal server but last time I checked it was too complicated for me. Same with Bitcoin Core.
Then there's Green wallet by Blockstream but I don't think they have Coin Control.

What makes ChipMixer special?
ChipMixer creates Bitcoin addresses (chips) and funds them with specific sizes. There are chips with 0.001 BTC, 0.002 BTC, 0.004 BTC and so on till 4.096 BTC. When you deposit your Bitcoins, you receive same amount in chips. For example you deposit 0.112 BTC and you receive 0.064 + 0.032 + 0.016. Each chip was funded before your deposit, so there is no link between them and your deposit on blockchain. They are already anonymous. With each chip, you receive its private key, so you can spend them any time you want.
Why us?
We offer the best privacy you can get from Bitcoin mixer.

  • you have full control over mixing - it makes process random
  • outputs are fungible - every chip is exactly the same
  • outputs are faster than inputs - from blockchain perspective, you spend them before sending to mixer
  • output may be higher than input - optional betting inside
  • you can use multiple small inputs to merge into one big output off-chain
  • outputs can be used instantly - private key is yours and you set miner's fee
  • no fee, donation only - pay as much as you want
  • no accounts, no bitcodes to link your inputs
  • optional signed source of funds

does the “cold device” in these cold storage mechanisms essentially just hold your private key and your latest known balance?
No. Tails forgets all data upon reboot. You have to have a papemetal/brain-backup of the seed.
You import the master-PUBLIC-key into an online system, for example Electrum running on your Android phone or tablet. That system knows your balance, because it is online and can derive all addresses from the master-public-key. But it can't sign any transaction, because it doesn't have the seed.
If you want to spend, you create an unsigned transaction on the online-installation, transfer it to the offline system, check it, sign it, double check it, transfer the signed transaction to the online system and then broadcast it from there. Sounds more complicated than it is. Works really good with QR-codes.
Here are some old videos explaining the process. The software has changed slightly in the meantime, but the process should be made clear form watching that. The first video is now actually redundant, because Tails exists and you don't have to create your own Linux live system that has Electrum.

How To Stake/Mine Coinevo

EVO Staking/Evo mining

Evo uses Proof of Stake consensus mechanism, which is different from Bitcoin's PoW (Proof of Work). Evo mining process in PoS system is called staking. The block producer will get 6.5EVO, as well as the transaction fees and gases as block reward. So the real reward is usually more than 6.5 evo in total.
Basic requirements for staking:
  1. Run a Coinevo fullnode, and keep online (Since Coinevo is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);
  2. Have some EVO in the wallet (fullnode)(Any amount of EVO can be used for staking, more EVO means higher possibility to stake).
If you have no EVO yet, please get some from market before you doing following staking settings.
Currently, Coinevo Core wallet is the only wallet that support Coinevo PoS staking. Note that other wallets like mobile wallet and Evo Electrum are not able to stake for the time being.
Two ways to stake:
Either way works in the same way for staking, so you can choose either method you like.

Method 1:Staking with evod (command line)

1. Run evod

Follow the guidance to run evod :
./evod -daemon 
Staking is default on for evod, so no need for other options if you only want to stake.

2. Send some EVO to your wallet

First you can generate a new address with:
./evo-cli getnewaddress 
This will generate a new address with Prefix '1'. You can send some EVO to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary EVO as you like for staking.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..
After the EVO node syncing to the latest block, you can check current balance with ./evo-cli getbalance or get utxo list with./evo-cli listunspent
Please do following steps after your coin is mature.

3. Check staking info

Check current staking info with:
./evo-cli getstakinginfo 
You might get the result like this:
{ "enabled": true, "staking": true, "errors": "", "currentblocktx": 0, "pooledtx": 0, "difficulty": 3693409.779133397, "search-interval": 1577, "weight": 309584575558555, "netstakeweight": 1948540143266404, "expectedtime": 805 } 
enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of EVO that is staking right now, with unit 10^-8EVO, here in the example, we have 0.532EVO staking. expectedtime stands for the expected time that you will get a reward, the unit is second.

4. How to stake if the wallet is encrypted?

If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet.
Coinevo wallet can be encrypted with encryptwallet . However, staking will be stopped when it is encrypted. For example, ./evo-cli getstakinginfo for a encrypted wallet:
{ "enabled": true, "staking": false, "errors": "", "currentblocksize": 1000, "currentblocktx": 0, "pooledtx": 94, "difficulty": 5788429.670171153, "search-interval": 0, "weight": 53206430, "netstakeweight": 2438496688951881, "expectedtime": 0 } 
See staking turns to false , which means wallet is not staking.
You can use walletpassphrase to unlock wallet for staking:
./evo-cli walletpassphrase "" 99999999 true 
After unlocking, you can double check getstakinginfo , it should look the same with previous unlocked result, staking become true.

Method 2: Staking with evo-qt wallet (official PC wallet)

Current supported platform: Mac/Linux/Windows.

1. Open Evo qt wallet

Launch the wallet.

2. Send some EVO to your wallet

If you already have some EVO in your wallet, you might skip this step.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..

3. Check staking status

The flash sign at the bottom of wallet shows staking info :
Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:
Hollow flash measn it is not staking
Possible reasons for not staking:
No flash sign means staking is disabled

About block reward

The block producer will get more than 6.5 EVO rewards, something to keep in mind:

How to disable staking?

Staking is by default enabled for Coinevo wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below:
1 Add -staking=false when running Coinevo node:
./evod -staking=false -daemon 
For qt wallet, it is like:
./evo-qt -staking=false 
2 Add config staking=false in evo.conf;
3 Encrypt wallet, since encrypted wallet will automatically stop staking.

Air-gapped z-addresses; Is ZecWallet an option?

I've heard of Zcash for a while, but it wasn't until recently that I tried my hand playing around with the daemon and wallets.
Obviously, there's no point in using ZEC if you're only using t-addresses, but my desire for a z-address capable wallet certainly narrows the choice of wallets available to me.
Running a full node is no problem for me; I'd like to take advantage of a GUI if possible though. For that reason, I am drawn to ZecWallet's full node version. But I'm still uneasy when it comes to key security. (Can anyone share their experience with the ZecWallet paper wallet generator?)
From what I gather there is no wallet with HD support for t-addresses, is that right? Not much of a concern for me because I am interested in the shielded pool. I just figured t-addresses would support Electrum-style seeds but apparently not?
Sapling addresses seem to be exactly what I want; in particular I am drawn to their reusability and ability to export the view key. I was hoping this would ease the process of securing and backing up my private keys.
Here's my key handling protocol I use for Monero:
1) Generate the wallet on an air-gapped machine
2) This gives you a mnemonic seed. I write that down and keep it as an analog backup. By using a passphrase in conjunction with the seed, I can effectively encrypt this paper wallet easily.
3) Export the private view key and address to an online machine and make a watch-only wallet. This lets my watching wallet see incoming transactions
4) When outputs are received, I have to export the list of outputs to the air-gapped machine. The air-gapped machine uses this data to make signed key images.
5) I export the key images back to the watching wallet. At this point, the watching wallet can see outgoing transactions.
6) Now I can create unsigned transactions with the watching wallet, sign them in the air-gapped machine, and transmit them via the watching wallet using my full node.
The major benefit of using Monero in this way is that I only have to make a human-readable backup of my wallet once and I'm set for life.
Obviously, Zcash is going to be a little bit different. Since the core client doesn't give us mnemonic seed phrases, that complicates backup a little bit. What's the best way to back up ZEC? If I keep an up-to-date backup of my wallet.dat is that all I need? Is there an option in the wallet to encrypt this backup as well, or do I need to accomplish that externally with the likes of Veracrypt? I must admit the idea of unencrypted wallet data being written to my disk makes me uneasy.
I see that there is an option in zcash-cli to import/export the view key of Sapling addresses. However, I can't see the option to do so in ZecWallet, and when I do so manually via the CLI nothing seems to be reflected in ZecWallet.
Is ZecWallet by its very nature an obligatory hot wallet, or am I missing some functionality in the wallet?
My end goal is to run a ZEC full node on Qubes and hold my coins in z-addresses. Qubes allows me to make virtually air-gapped VMs to greatly simplify key management.
So for example when I use Bitcoin, I have a networked VM that runs a Bitcoind + Electrum Personal Server + Electrum Wallet stack, where I import my master public key. When I need to sign a transaction, I spin up a networkless VM equipped with Electrum and my private keys. Qrexec let's me easily ferry unsigned/signed transactions back and forth between the two VMs. Overall this provides a decent UX with above-average security and privacy. I'd like to port this general setup to Zcash.
To do so, I need a GUI wallet that supports both z-addresses and public/private key splitting. Does such a tool exist? (Can Electrum Personal Server be ported to ZEC?) If not, how can I streamline this process with the CLI?
I'm more familiar with Monero than Bitcoin, so the Zcash/Bitcoin CLIs are still a little foreign to me, though I am not "afraid" of CLI wallets in general. My Cryptonote muscle memory makes me prone to annoying little syntax errors I'd much rather do without.
My plan is to buy ZEC from Coinbase Pro, withdraw to a t-address, and then sweep my coins to a z-address. I want to monitor the balance of both t-addresses and z-addresses (and later send transactions) without ever exposing my private keys to the Internet.
However, it seems like the Zcash CLI is my only viable option for z-address watching wallets. Should I just play around on testnet until I get more familiar, or is there a GUI wallet solution out there that fits my needs? Does anyone have a cheat sheet for doing this via the CLI that could help me along the learning curve?
TL;DR New to Zcash, need advice as it relates to wallet backup, watching wallets, and z-addresses.
Assistance is much appreciated!
Edit: I don't suppose there's a way to use a Trezor Model T with a full node and or z-addresses?

What makes ChipMixer special?
ChipMixer creates Bitcoin addresses (chips) and funds them with specific sizes. There are chips with 0.001 BTC, 0.002 BTC, 0.004 BTC and so on till 4.096 BTC. When you deposit your Bitcoins, you receive same amount in chips. For example you deposit 0.112 BTC and you receive 0.064 + 0.032 + 0.016. Each chip was funded before your deposit, so there is no link between them and your deposit on blockchain. They are already anonymous. With each chip, you receive its private key, so you can spend them any time you want.
Why us?
We offer the best privacy you can get from Bitcoin mixer.

  • you have full control over mixing - it makes process random
  • outputs are fungible - every chip is exactly the same
  • outputs are faster than inputs - from blockchain perspective, you spend them before sending to mixer
  • output may be higher than input - optional betting inside
  • you can use multiple small inputs to merge into one big output off-chain
  • outputs can be used instantly - private key is yours and you set miner's fee
  • no fee, donation only - pay as much as you want
  • no accounts, no bitcodes to link your inputs
  • optional signed source of funds
  • we wait 48h for your input transaction and we can wait more on request
  • lightweight pages, no javascript required
How to use it with example
Step 1 - deposit
You receive input address. You deposit 0.1 BTC on received address and wait for one confirmation.
Step 2 - mixing
Your 0.1 BTC is exchanged for chips: 0.064 + 0.032 + 0.004.
You click on split button for 0.064 chip exchanging it for two 0.032 chips.
You click on split button for 0.004 chip exchanging it for two 0.002 chips. You click donate on smallest chip. Thank you!
Now you have 3 * 0.032 + 0.002. You click withdraw all.
Step 3 - withdraw
You see list of four private keys. Each marked with its size (3 * 0.032 BTC and 0.002 BTC) and public key. There is no on-chain connection between them and funds you deposited.
You import them into your wallet Electrum wallet and they are ready to be spent.
Total mixing time: 1 blockchain confirmation
Total cost: 0.002 BTC donate. You pay what you want.

FinderOuter: the bitcoin recovery tool

Link: https://github.com/Coding-Enthusiast/FinderOuter
The FinderOuter is a bitcoin recovery tool that focuses on making the recovery process easy for everyone. There is no need to read long guide pages to learn how to use the application. Instead it will always be as easy as filling some boxes, maybe selecting some options and clicking a button all in a user-friendly GUI. Each recovery option is written from scratch and all parts down to the basic cryptography used (such as SHA, ECC,...) are specialized for maximum efficiency.

Available options

1. Message signature verification

User can enter a message signature here to verify it. In case there is a problem with the message (except being an actually invalid signature), the code can search to find the common issues that some signing tools have and fix them.

2. Missing Base-58 characters

This option helps recover any base-58 encoded string with a checksum that is missing some characters. For example a damaged paper wallet where some characters are erased/unreadable. The position of missing characters must be known. It works for (1) WIFs (Base-58 encoded private key) (2) Addresses (Base-58 encoded P2PKH address) (3) BIP-38 (Base-58 encoded encrypted private key).
There is also a "special case" where a compressed private key is missing 3 characters at unknown positions.

3. Missing Base-16 characters

This option is similar to previous feature but works for base-16 (hexadecimal) private keys. It currently requires an address and only checks compressed public keys. Unlike the other options, this one is very slow since it depends on ECC and that is not yet optimized.

4. Missing mini-privatekey characters

This option is similar to 2 and 3 but works for mini-privatekeys (eg. SzavMBLoXU6kDrqtUVmffv). It requires an address to check each possible key against, as a result it is also slower since it depends on ECC and has 2 additional hashes.

5. Missing mnomonic (seed) words

This option works for BIP-39 mnemonics (others like Electrum will be added in the future) that have some words missing. It requires knowing one child key or address created from that seed and the exact path of it.

Future plans

[Idea] Bech32 encoding of private keys

Ever since I saw BIP-173 I was excited to see the encoding used anywhere other than addresses. I've done some search but apart from some comments here and there I haven't been able to find any major work done (please let me know if you know of any proposals). Here is my idea of addressing some of the problems with current encoding of private keys:

Using Bech32 encoding instead of Base58

While writing a private key recovery tool I've felt how hard it is to come up with an optimized algorithm to recover a key that is missing a couple of characters (eg. a damaged paper wallet). That is not true with Bech32 being a multiply of base-2 algorithm is inherently faster, and the checksum is not a bottleneck since it is not a hash algorithm. Bech32 also has the benefit of having error detection.

Script (address) type

Currently when a user imports/sweeps a private key in a wallet client, that client either has to explicitly ask user for the script type (like Electrum) which means user is exposed to complications and has to be familiar with script types; or the wallet has to construct all script types and scan the blockchain for all of them (like bitcoin core) which adds more burden on the client. If the encoding included a script type that becomes so much easier.

Locktime!

Another burden on both clients and users (specially full node users) is the time consuming need for a re-scan of the entire blockchain to find the historical transactions that belong to an imported key. A timestamp can make that process a lot shorter. Using locktime (similar to last 4 bytes of any transaction) the key string (aka WIF) could include either a block height or a date-time value of when the key was created.
This idea was added to Bitcoin.Net library as an "experimental" class. Direct link to the code
Here is an example with a random key from Bitcoin.Net KeyHelper class:
Original WIF (Base-58): L28Peud5cQcijrtMthAdUS8FynpM8PKZtnoUZb1VAio9WxKoebHt Key bytes (Base-16): 92734fe879f662ff8ee4eb87dd019425e2ee73ff3edd0c4dc3def2f71e1a6a69 Version byte (ie. the script type): 0x02 or P2WPKH Date UTC: 5/4/2020 7:11:05 AM H.R.P.: bprv New encoding (versioned Bech-32): bprv1zjfe5l6re7e30lrhyawra6qv5yh3wuull8mwscnwrmme0w8s6df5sns90tcqqzyen4e 
Note that key is encoded the same way an address would be encoded (version byte is added separately as a 5-bit value instead of 8-bit).

Winter is coming, get ready to overthrow the establishment! (I mean, make a millionaire.) [Drawing Thread #38]

It's cold. (I've never watched an episode of Game of Thrones, please enjoy the reference if it makes sense! If it doesn't, it's treason, then. And if I made anyone cringe, I'm sorry. )

In Case You Missed It:
TL;DR: Leave a comment on this thread. A random user will be chosen, and everyone donates a dollar to make a millionaire. You are welcome to spread this thread via upvoting, telling friends and family, and sharing on social media! If you'd like to be reminded to donate to the winner by RemindMeBot, click here!
What is this, anyway?
Three years ago, a Redditor posted an idea in /Showerthoughts that speculated the fact, if a million people picked a certain Redditor and all donated just $1, they would have the power to make someone a millionaire.
This subreddit is an embodiment of that showerthought, and the monthly drawings are the attempts to make it happen.
We need your help to keep this running, which amounts to only $1 a month to make someone's day. In the long term, that’s $120 every decade, which is a much more affordable price than other expenses. How does it work? Below, you will find an explanation on entering, rules to keep in mind, the selection, and other important things to note.
How to enter:
  • REQUIRED: Leave only one (1) top level comment in reply to this thread! Replying to other comments will not count. It is highly recommended to comment "RemindMe! 3 days Donation for /millionairemakers", which will remind you via PM to donate.
Important Rules:
  • Only ONE top level comment per person (replies and subsequent-level comments aren't included), but feel free to reply to other comments. Making duplicate top level comments may result in exclusion from entering. Go to me to ensure you don't accidentally double comment.
  • If, by any chance, you do double comment, delete any extra duplicates ASAP, ideally before the thread is locked in 24 hours, as any chosen draws found to violate this will not be eligible to win, and will be banned from the subreddit.
  • Your account must be older than 30 days with some amount of activity. Throwaway accounts with very minimal activity will also not be eligible. This is to prevent multiple entries from the same person.
How will the winner be picked and how can you donate?
  • After 24 hours, this thread will close, and the method of selection will begin.
  • While attempts to make the selection method similar to 2017’s have been performed, it still varies from the original. For an example from a prior drawing, see [Draw #36]. For archival purposes, please click here for the original selection method.
  • Method's TL;DR: Your number is assigned by sorting the comments by old, resulting in the first commenter being 1. The list of comments will be publicly released for the community to verify per their own accord. The subreddit then waits for a randomly generated block (a string of numbers) from Bitcoin's blockchain, after a preselected date and time, and calculates the winner using a formula described in the posts mentioned above.
  • Comment IDs are downloaded at 2:00 UTC, three hours following the thread being locked. There will be a trial run prior to the time listed, one at the time listed, and one trial run thirty minutes after. If it is shown that the deletion of comments has occurred between any of the trial runs, or technical difficulties, the retrieval of the comments will be delayed by an hour, following the same procedures.
  • While not necessary, to determine if you are on the list, please go to your comment and save it. The comment ID is what gets recorded and selected, which looks like this: e3yxpj4.
  • The user who created the winning comment will be informed of their luck and will provide any information necessary for their chosen payment methods (mods will help set this up if needed).
  • The generous Reddit community donates to this lucky person, hopefully making some worthy soul a millionaire! A donation table will be stickied to the winner’s post, giving users the freedom in how they donate.
  • The lucky Redditor follows up with a thank you within the next days, revealing to the community exactly how much was raised and thanking their generosity.
Reminders
  • Take the time you have available now to setup your PayPal, Square Cash, and Google Wallet account, and/or cryptocurrency wallets. (Note: Some services may not be available depending on where you reside.)
  • To buy any cryptocurrencies, you may use Coinbase for purchases using your bank account.
  • To store cryptocurrencies, there are many accessible wallets, and if you win, you will be guided on which ones to download. For Bitcoin and Bitcoin Cash, it’s recommended to use the Electrum and Electron Cash wallet for Mac, Linux, and PC.
  • Please try your best to donate a $1, no matter who wins. Every single dollar, cent, anything really counts, so please take the effort to remember and go through with it.
  • If you want to be reminded to donate, please comment "RemindMe! 3 days Donation for /millionairemakers".
  • Spread the word! The more people who participate, the better this gets for everyone! There has been a correlation between this subreddit making it in /all and an increase in donations.
  • Try to cross-post to relevant subs, and upvote. There is a correlation between reaching /all and the amount of donations for the winner. (Please don't spam other subs though. We're not trying to make any enemies here.)
  • If you are under 18, please talk to your parents to get their consent to participate and use their help to setup a PayPal account.
MOST IMPORTANTLY
Remember, this is about generosity, making history, and coming together to make someone's life better. It takes three minutes to donate a bit to the winner, whether you're well off and want to donate a couple bucks, or going through tough times and can only donate a few pennies. Every cent counts.
Note about legality: This is NOT a lottery. You don't have to pay to enter. No prizes are given away directly by the moderators of this subreddit (the moderators will never even touch your donations; this is done voluntarily). As for gift taxes, according to the IRS, they're paid by the donor, and any donations under $14,000 is not taxable.
If a lone $1 can get you ice cream (I did eat a Frosty this week), imagine the possibilities with $1,000,000. You can start a loan for a new vehicle, raise money for a TV, or pay gas bills to stay warm!
One million dollars can keep someone from the pain of the frost and cold. Spread the word: have your friends and family comment, post the link to your friendly-neighborhood social media network, and share it to anyone interested.
Let's heat a millionaire!
The cold of the night,
Whether sweaters or letters,
Today, set things right!
