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?
I am thinking that it is impossible that there is no at least someone in his life knows about his password. How about he has wife? or children? or girlfriend if he is still not married. Well I guess he also share his success and joy to his love ones because a person who has a lot of achievements and success can make a big rumors even though he is not speaking about it, his works and actions will do it.
