I've received many questions lately, but by far the most common question is “What's the best way to secure #Bittcoin?”

🧵So here’s a thread with my opinion on securing #Bitcoin
The first thing to understand is that there’s no "best way", but always a tradeoff.

You can always find ways to make it harder for someone to get your #Bitcoin, but if you over-complicate it, you could end up making it even too hard for yourself - many lost their funds this way.
Your goal should be to balance usability and security the way which works best for you.

This means very different things for different people, depending on your technical experience, understanding of Bitcoin, how much you are holding, etc.

“Early in life I have noticed that no event is ever correctly reported in a newspaper, but in Spain, for the first time, I saw newspaper reports which did not bear any relation to the facts, not even the relationship which is implied in an ordinary lie. I saw great
battles reported where there had been no fighting, and complete silence where hundreds of men had been killed. I saw troops who had fought bravely denounced as cowards and traitors, and others who had never seen a shot fired hailed as heroes of imaginary victories; and
I saw newspapers in London retailing these lies and eager intellectuals building emotional superstructures over events that never happened. I saw, in fact, history being written not in terms of what happened but of what ought to have happened according to various party lines.”

I've received many questions from people considering to set up a #Bitcoin multisig wallet but confused about the backup process, what should be backed up, and why.

🧵So here's a thread on backing up multisig wallets - what, why, and how.
The main caveat in a multisig wallet is that, while you need only a threshold of devices (ie. 2 of 3, 3 of 5, etc.) to sign a transaction, losing access to even a single device could potentially prevent you from being able to spend the funds - if you don't back up properly!
The reason is that (usually) in order to make a Bitcoin transaction, it is not enough to be able to sign it, but you also need to provide the "terms for spending", that is, the Script (code) that is used to lock the coins.

math is hard ImageImageImageImage
Buy 1 sat, sell it for $26K, use that to buy 1 BTC, divided that into 100,000,000 sats. Repeat.

Checkmate maxis.
lol bet these guys are like “why’s everyone talking about pizza?”

🧵Thread: 10 Rules for Verification on a #Bitcoin Hardware Wallet 👇
Rule #1: DO NOT TRUST THE COMPUTER SCREEN.

The very reason for using a hardware wallet is that your computer IS compromised, trusting it makes using the hardware wallet an expensive security theatre (or 2FA at best).
Always verify on the HWW device screen!
Rule #2: Verify your "receive" addresses BEFORE accepting funds.

A compromised computer can be tricked into displaying addresses that belong to an attacker. The only way to make sure you own the addresses is to display them on the HWW device and verify they match.
