Hi I'm a newbie. I think the bitcoin will disappear if the owner is dead.
No it won't disappear just tuck on wallet which can't be access by anyone since private key is not available. it would be keep in the wallet forever I guess lol.
That' s right. The bitcoin will remain in the wallet forever. No one will ever touch that coins unless you told someone all the address and codes. What only disappear is the dead person. If the family would have an idea about the wallet but do not have the necessary information, the wasted bitcoin would add the pain they are going through.
