12 bitcoin security levels: - level 0: on an exchange. You don’t really own anything. - level 1: hot storage on a closed source shitcoin wallet (like @Ledger) - level 2: hot storage on an open source bitcoin only wallet (like @bluewalletio or @SparrowWallet) - level 3: cold storage on a usb hardware wallet with shitcoin support - level 4: cold storage on a bitcoin only usb hardware (like @COLDCARDwallet mk4 or @BitBoxSwiss) - level 4: cold storage on a bitcoin only airgapped hardware wallet without reproducible builds (like @KeystoneForBTC) - level 5: cold storage on a bitcoin only airgapped hardware wallet with reproducible builds (like @FOUNDATIONdvcs Passport) - level 6: analog-only airgapped cold storage (Passport supports this) with self generated ephemeral seed - level 7: cold single seed + passphrase (protect against seed compromise) - level 8: Shamirs secret sharing cold single seed (protect against seed compromise & introduce fault tolerance) - level 9: hybrid 2/3 multi-sig with 1 hot key - level 10: full cold 2/3 multi-sig - level 11: hybrid 3/5 multi-sig with 1 hot key - level 12: full cold 3/5 multi-sig Could be split up further but might not make a lot of sense. Bonus points for connecting to your own node at any level. I’m sure many will disagree somewhere. What would you change? What would you remove or rank differently? Note higher security is not always the best fit for your situation.

Waardevol advies en inzicht van een van onze GRYP-partners!

@MRBFREEDOM @FOUNDATIONdvcs @SeedSigner 💯 especially the large smartcard version

@BitsagaRob @FOUNDATIONdvcs @SeedSigner also very good.

I’ll never sell Ledger at Bitsaga. Do yourself a favor and get a proper hardware wallet instead. My personal recommendation is the Passport by @FOUNDATIONdvcs: air-gapped, great UX, and an excellent product.

@Code3Bitcoin Right there with you bro

@BitsagaRob Me in 2013

This man was mass-producing millionaires in 2013 and nobody showed up

@UnruggableGG @FOUNDATIONdvcs top combo!

@BitsagaRob @FOUNDATIONdvcs Totally agree with that @BitsagaRob. Passport by @FOUNDATIONdvcs is my top recommendation for most of my Become Unruggable mentee's. And its all a device i use personally day-to-day, paired with my BULL Wallet, works like a charm!

@hmichellerose absolutely not. But he surely did.

@BitsagaRob I don't think his goal was ever to produce millionaires.

@FujiwaraTD @kayathepitbull @FOUNDATIONdvcs Seedsigner!! way better even

@kayathepitbull @BitsagaRob @FOUNDATIONdvcs The ultimate air-gap is having no battery. If it doesn't have a battery, it definitely isn't getting remotely hacked while sitting in a drawer. And it can't explode. Trezor!!

@zherbert @FOUNDATIONdvcs

@BitsagaRob @FOUNDATIONdvcs 🙏 We have something coming for Passport Prime that is going to completely obsolete Ledger and allow all their customers to switch over to our open source, assembled in the USA next gen hardware

@FOUNDATIONdvcs If you’re using multisig, you should use hardware wallets from different manufacturers. You can find the Passport in my shop, along with other devices, here: bitsaga.be/bitcoin-produc…

Thank you Satoshi 🧡

@Nishadow @CaitlinLong_ Most certainly!

@BitsagaRob @CaitlinLong_ Bitcoin doesn’t need a figurehead. But if it did, it would be Andreas Antonopoulos 🪬
