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 or the creator of bitcoin dies, bitcoin will not die too because i think there are some of the relatives or family members who also knows how to manage it for bitcoin will continue and will last forever. If it does not there should be some intructions written on a paper on how to control it.
