I have accumulated some Bitcoin and other alts. Most of my holdings are in a single wallet yet I have a few on different platforms and one left on an exchange. I have tried to explain this to my spouse yet there is not a full understanding. If I died I am confident that all of this would not be recovered.
This weeks project is to write an encrypted note detailing where are the holdings are and how to access them. Even with access, the knowledge is not there to be able to convert the holdings to fiat if necessary.
What is your situation ?
Just hand all your crypto related information to the one you trusted, in your case, your spouse. Don't mind being him/her not fully understand. Put all the ways, directions, procedures on whatever writing tools you preferred and hand that to your spouse. In that way, accessibility is still possible because some information have been handed.
The obvious thing to happen here is, coins will be untouchable if it not be handed. But I think in some of the exchanges, if they saw some account that is not active for a required period of time, they will get the funds and questions will just be asked once the real owner came back. So it's better to store coins from a ledger or any hardware wallet. The coins will remained forever there if no one have an accessed to it.
