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 if the person die and no one knows about his/her password it would still remain in his/her wallet and it will not circulate again to distribute to other because all of the users of bitcoin is unknown, So the you might be correct that the 1 million bitcoin will not be move in the circulation and the 20 million bitcoin would be circulated.
