Dear team
I need to know that if a bitcoin holder dies with 100btc. Then what happended to btc ? Useless
If family member knows no problem. What if not
Yes it will be useless as no one knows anything about it even its password or key to his/her wallet. Thats the reason why we should keep it as a secret to someone who is close to us so that our money will have value and be worthy. If someone know your private keys then there is someone who can used it whenever you die.
