Did you guys teach your family members on how to access and use your Bitcoin in case you will die?
Do you want to take your Bitcoin with you when you're gone.
Let me hear it from your own opinions...
I also think about this how those people who hold large amount of bitcoin think if this kind of event happened? Is there any paper or documents that has an attachment of information about his bitcoin. To pass to their family or friends.
They probably just gave 1 person they trust instructions on how to open the wallet and eventually sell it. Not much other ways around it , maybe they got a lawyer who will notify the family after the death.
