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.
It will not disappear to the bitcoin wallet of the person. It will remain forever, that is one of the best feature of cryptocurrency. It is decentralized, no one owns it. As long as you have the private keys, you are the only one can access your wallet.
