This was very informative and not something we think about every day. If you store Bitcoin on online wallets, you have to consider the passwords and the multisig options too and also the devices used for the 2FA.
I wonder how many people have taken their Bitcoins to their graves already, with lost passwords or private keys that were hidden. It might even be that the relatives did not know what Bitcoin was, and they
might have thrown away the "paper work" and the paper wallets with it. This is why communication is so important, when you use Bitcoin. Someone you trust, must know how to access it, when you are gone.
Lesson learned, thanks OP for the reminder.
