Inheritance is something we all wanted, especially for Bitcoin. The problem however is on how you secretly keep the seed phrases or private keys for the next generation to figure themselves out, especially in terms of calamities.

Writing them down on a piece of paper or notebook won’t work in the long run, because it can be damaged by fire or water and the ability to access will be gone forever. Engraving them in an aluminum steel would do, but where would you keep it?

Maybe in a safe aluminum steel box with a sign “Don’t open until Day/Month/Year” and giving them some out of the box clues about the passcode that even intruders may find it hard to decipher or so.

Just my opinion only.
