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?
Anyone who possesses suitable amount or huge amount of bitcoin should be having full security of it. Full security which means for what ever happens to him, there should be someone or somebody will inherit all his properties including bitcoin as per legal process. The owner should consult legal counsel
to arrange it.
