Bitcoin is just as much about yourself. if you don't reveal the details of a person's personality to others, everything about him will be lost when he dies. Bitcoin only has 1 key. if you keep it without telling relatives. then there's no use after you die. actually some time ago there was a crypto project that almost solved this problem. but the project stalled. The project has a blockchain-based storage system, and will send the key that we store to the account of someone we trust after our account is inactive for 30 days or more (according to our settings)
