If some people has lots of bitcoin in their offline wallets and they die or lose memory.
Then those coins will be out of circulation right? Or is there any way to recover them?
If they forgot or lost all the informations about that wallet, the bitcoins will remain there forever. I dont think there is anyone that can break into a totally blocked wallet with bo info about it. Maybe only the Nasa best hackers but even for they its hard. Maybe for us that is a good thing because if the total supply is lower than the price is higher.
