I just got this question in my mind. What will happen if no one knows about the pasword of his/her acount will it posibly deduct to the main supply of bitcoin? Example bitcoin was 21million supply and one man got 1 million bitcoin he was holding and suddenly he died no one can open his wallet is it posible that the remaining 20 million bitcoin forever?
As for me, I will always share it to my loved one whom I can trust the most. It is hard not to share it because no one can access your wallet but only you. Bitcoin wallet is not like banks who has beneficiaries, in the case the depositor will die, the beneficiaries can withdraw all the savings of the depositor. So, in bitcoin wallet, I will make sure a certain loved one of mine knows about it. We do not know what tomorrow may bring, but death is certain.
