After using nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl for the last couple of months, I'm convinced it's the best way to secure your bitcoin. Why?
It's trustless, like the ethos of Bitcoin. You're using off-the-shelf hardware, the code is open source, keys can (and should) be generated offline and the device isn't even storing your them!
Keys are stored in a QR code and should be backed up to something physical (stainless steel, etc). A passphrase is crucial. It provides the final level of protection from various forms of attack.
No need to twist yourself in knots and trust secure elements, closed-source code, kill-switch PINs, etc. After using a Trezor One for years, I'm convinced SeedSigner is the way.
