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?
In my own personal opinion, if the owner of bitcoin dies i think bitcoin will still live because maybe there are some people like a family member or a friend who also knows how to control bitcoin for bitcoin to live and to continue. Bitcoin will continue as long there are people who still invest in bitcoin.
