What will happen??
No one will have the BTC address. Hence will them isolated?
In FIAT, people can handover money to someone.. So, i predict BTC will be disappeared gradually.
chances are that his assets and assets will not move at all if his arit becomes a treasure, if he does not give or inform his family like his son or his wife or his parents so when he dies his assets can be handled by the family , it should be so.
