Bitcoin Security Levels: How safe are your sats?

Not all Bitcoin holders have the same level of security. Here are 6 Bitcoin Custody security levels in one post.

Level 0: Bitcoin on an Exchange

💀 If your coins are on an exchange, they are not yours.

🚨 Risk: Hacks, insolvency, frozen accounts.

🔑 Not your keys, not your coins!

Level 1: Hot Wallet on Mobile or Desktop

🔥 You own your private keys, but they are online = vulnerable.

✅ Better than an exchange, but not secure for long-term storage.

💡 Recommended wallets: BlueWallet, Sparrow.

Level 2: Hardware Wallet with Shitcoin Support (or closed source Hardware Wallet)

🔐 More secure than hot wallets, but:

🚨 Many hardware wallets (e.g. Ledger) support altcoins and are not fully Open Source.

❌ Unnecessary attack surface!

Level 3: Bitcoin-Only Hardware Wallet

✅ No altcoin support = reduced attack vectors.

💡 Recommended wallets: BitBox02

➡️ Want even more security? Airgapped wallets! 👇

Level 4: Bitcoin-Only + Airgapped Hardware Wallet

✅ Even fewer attack vectors since transactions are signed via QR code or SD card.

💡 Recommended wallets: Foundation Passport, Coldcard, SpecterDIY

Level 5: Single Seed + Passphrase (Cold Storage)

💪 Extra security: Even if someone finds your seed, they can’t access your funds without the passphrase.

Important: Never store your passphrase digitally

🔐 Recommended wallets: Foundation Passport, SpecterDIY

🚨 Warning: Higher risk as you now have two single points of failure. Your setup must be well thought out.

Level 6: Multi-Sig Cold Storage

🛡️ Multiple keys required to spend = maximum protection.

✅ No single point of failure.

👨‍👩‍👦‍👦 Ideal for families or businesses.

🔐 Can be customized:

➡️ 2-of-3, 3-of-5, mixed hot & cold wallets.

💡 Recommended solutions: Unchained Capital, Sparrow, Blockstream Jade

That's a wrap! Let me know what you think! Do you agree? Did I miss something?

Staying solvent.

Inheritance planning through distributed, partially custodial multisig

Inheritance planning through basic training of next of kin on the mechanics of moving coins and using exchange accounts.

Supplier diversity in your signing hardware stack for multisig

Nonexistent signing capability in your living space

Redundancy on your signing devices (cloned devices)

Redundancy, password security, firewalling, duress passwording, portability and geographic separation on watch-only (non signing) laptops, desktops and mobiles running your transaction building and UTXO management software

Lockable, tamper sealed seed backups on metal

Not wearing Bitcoin shwag

Geographic and time delayed separation of signing devices, key backups and your residence

Ready access to firearms in your personal space

Establishment of duress words with trusted (and preferably armed) people

Gotta love having this shlock advertising pumped into your house during a sports game. People are going blind from using this drug.

Yes. A melting pot. And a frog screwing a beaver.

Yeah and it’s cool too if you have sensitive text to send home to yourself on your file server, you can encrypt it before you send it. Then decrypt it when you get home.

Just like Bitcoin though, key management is paramount. There’s no sense sending yourself or others encrypted data if the decryption key is readily available for use on the same device without a passphrase.

The recommendation is SHA-256 4096 bit with a strong passphrase. Nobody is cracking that. And if you’re sending data that sensitive, you likely have bigger problems, like Jason Bourne coming to your door lol

The biggest problem I find is on-boarding friends to PGP. It’s so easy, but as usual most people aren’t interested in learning it BEFORE it’s needed.

Self PGP encrypted text manually pasted into WhatsApp. Share public keys with your contacts so they can send stuff for you to decrypt. And vice versa.

It’s clunky but it’s pretty damn secure. The following message is what “GFY” looks like encrypted to my public key, for example. I use InstantPGP on iOS, Kleopatra on PC and Linux. And GPG Keychain on MacOS.

It’s cool when you see a set of rabbit tracks leading to one of these, but no rabbit tracks leading away from it. And a big wing span.

I definitely understand why the Egyptians held them as gods.

My cats for me. All they do is sleep, eat, hunt, fight and fuck.
