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 think the bitcoin that was mined by a person who died will vanish on that person's wallet also as time passes by and will cycle again to the system of blockchain making it exist still even though the owner died. I was also thinking about this stuff hoping that someone would make something that will assure that all of someone's bitcoin will end up to the family as that person dies.
