The most non-technical #Bitcoin multi-factor security (128-bit secure)...
Split 24 seed words in two, and separate each half.
Plate 1 = words 1-12
Plate 2 = words 13-24
Store multiple copies of the plates in separate locations.
NEVER store plates 1 and 2 together!

I can't ignore this any more!
My Google Pixel phone was listening to a very private conversation with my old friend on Friday night.
When I typed a single letter into Google Maps today, it suggested the exact address in Ireland he mentioned.
We discussed #Bitcoin stuff too. 😬

A passphrase made up of six BIP39 words strung together provides 66 bits of entropy, or 7.38 x 10¹⁹ possible combinations.
If someone discovers your seed words, and this is the only thing standing in the way of them taking your #Bitcoin, then you probably only have a few hundred years before they succeed in a brute-force attacking your wallet...
...then again, how would they know there's a passphrase, and so why would they bother?

24 seed words protect a #Bitcoin wallet with the complexity of about 10⁷⁶ different possible word combinations... to give you some idea of the size of that complexity, there are about 10⁸⁰ atoms in the entire universe!

Best practice #Bitcoin
1. DCA sats
eg. @SwanBitcoin or @relai_app
2. Run your own node
eg. @umbrel or @nodl_it
3. Use open-source wallet
eg. @SpecterWallet or @SparrowWallet
4. Airgapped signing device
eg. @COLDCARDwallet or @SeedSigner
5. Backup seed on metal
eg. @BitPLATES

My friend wants a self-sovereign #Bitcoin setup.
I'm thinking about recommending this, but would appreciate your thoughts...
1. Build your own node @Raspberry_Pi 4 model B (4GB+ RAM) and Crucial X6 1TB SSD portable drive.
2. Run an OS with #Bitcoin core and Lightning ⚡@umbrel
3. Use an open-source wallet @SpecterWallet
4. Understand the importance of having an air-gapped signing device @COLDCARDwallet or @SeedSigner
5. Backup your 12 or 24 seed words on metal @BitPLATES Domino plates
6. Use multi-factor security eg. passphrase, or multisig

These are my 24 #Bitcoin seed words.
They are now in the public domain forever.
An infinite number of passphrases can be added to these seed words to create infinite accounts.
With strong passphrases, these seed words alone will never reveal my sats.

If you're new to #Bitcoin
-Buy an air-gapped signing device
-Write down seed words + passphrase
-Test that you can re-create your wallet
-Backup seed words + passphrase on metal plates
-Destroy paper copy
-Hide metal plates (inc. any extra copies) in separate locations.

Bitcoin is the only asset that comes with built-in 'plausible deniability'.
1. Keep a small amount of sacrificial #Bitcoin in a wallet created with ONLY seed words.
2. Keep your main funds secure in a secret wallet created with seed words + passphrase (must store separately).

Your #Bitcoin isn't backed up until you’ve checked that your backup works...
1) Create a wallet
2) Send small amount of 'test' sats
3) Delete the wallet
4) Restore it with backup words
5) View sats if backed up correctly
6) Lose sats if not
7) Repeat with more care if necessary

At first glance 0.0021000 BTC looks like 21,000 sats, but it's not!
Decimal places create a serious risk of human error that will only be fixed when denominating in sats.
Should there be an agreed $BTC price point for #Bitcoin software & hardware manufacturers to #defaultsats?

Seed words are a human-readable version of #Bitcoin private keys, which can create, manage, and backup a Bitcoin client (software wallet).
A Bitcoin signing device (hardware wallet) can be used to generate seed words, but most importantly, keeps them separated from the internet.

Unpopular #Bitcoin opinion:
'Seed words + Passphrase' is superior than (multi-device) multisig because:
1. Easier to setup than multisig.
2. Easier to restore than multisig.
3. Provides a 2nd factor of security using only one device.
4. Easier to backup on robust material.

When the internet standards track protocol (HTTP/1.1) was published in 1997, a return code (402) was created to indicate that a payment is required.
No protocol was created to use it, and it still sits as "reserved for future use".
#Bitcoin fixes this.

Over the course of history, many governments have confiscated their citizen's gold.
If this ever happened with #Bitcoin it might be wise to have a genuine wallet with a physical backup of 24 seed words to sacrifice.
I certainly wouldn't recommend that you hide another wallet.

If you split 24 seed words in two, each half is protected by 128-bit security.
Plate 1 = words 1-12
Plate 2 = words 13-24
Store plates in different locations.
This is the most non-technical #Bitcoin multi-factor security.

Only the first four letters of each seed word are required to re-create your #Bitcoin wallet.
eg. SPHE from the word 'sphere'
Simply add dots with a pen, then indent onto those dots to create a permanent record of up to 24 seed words per plate.

Helping to secure the #Bitcoin network isn't expensive, but is invaluable!
I run a full #Bitcoin node on a @Raspberry_Pi, which uses 6 watts per hour when all four cores are in use.
If you pay $0.30 per kWh, this equates to $0.0018 per hour, $0.0432 per day, or $0.30 per week.

Why store your #Bitcoin seed words on a metal plate?
1. A solid piece of metal is robust.
2. Multiple small pieces could result in permanent loss of data if separated.
3. Screw-close mechanisms could become permanently sealed shut if galling or cold-welding occurs over time.

Don't split up a #Bitcoin private key by splitting up seed words; it massively reduces security against brute-force attacks:

#Bitcoin'ers should aim for self-custody.
Self-custody should include multi-factor security protection.
Multi-factor security should involve distributed parts.
Distributed parts should be resistant to single catastrophic failure.
Multiple copies should be made to avoid loss.

A #Bitcoin private key should never be left on a computer, but instead saved onto robust metal. 🔥
One plate to preserve half the key (seed words).
A second plate to preserve the other half of the key (passphrase) in a separate location.

I think @GeorgeGammon is a great asset to #Bitcoin but he's obviously stuck in the weeds.
