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.
The only way for cyrptocurrency to be handed to other wallet is through block chain and because of that, those people who died without using their cyrptocurrency or passing the password will be just a waste and will not circulate on the market.
there may not have that for or to be pass with other for cause only he is the one to be able to know more about what he may save for even how many is that there is still that it will may look for nothing.
