I’m trying to think through this now. I have one and also a trezor.

If I think with the “human cattle car” mindset (if i were to be taken no clothes no possessions, all personal and cloud storage gone, all scraps of paper gone, no access to physical locations of the past) could i still retrieve my bitcoin?

What I like about the trezor is that I know for sure I have my seed memorized well, funds safu.

With a seedsigner multisig, you have to scan in three pubkey QR codes to begin with. Then sign with either qr or seed entry. A lot to memorize.

I suppose i haven’t dug into seed signer single sig. But also i tried my trezor key on seedsigner and it apparently is in an incompatible seed format.
