I like seed phrases stamped in steel. EMP, fire, and flood. If you know where to find the plate you can recover your seed after the apocalypse even. A hundred years can pass and your offspring can still recover my keys.

Say they pull a scorched bitkey and phone from the ruined basement of my old house. Would it work? Probably not. SSDs degrade and corrupt over time just sitting in a drawer.

Bit Key is for helping boomers get off exchange. Protects people for losing their keys.
