Yo,
So apparently there's like 4-6 million bitcoin that are lost and gone? Just curious if there was any ideas or plans to update the protocol to replace the lost bitcoins if there was a consensus, if that is even possible.
Lost Bitcoin refers to all those wallets that wallets are currently inactive. However, there are many investors who have Bitcoin holdings in their wallets but they have not yet activated their wallets. But whether it will be possible to reduce the lost Bitcoin total supply through any process, only those who are Bitcoin developers can say for sure. However, for the time being, it is not possible to say with certainty whether all these changes or updates will be possible without Satoshi Nakamoto.
People who buy and hold bitcoins but can't exchange their wallets will never get that bitcoin back and no one will ever get it back. They will remain that way for life. Satoshi designed Bitcoin in such a way that as long as you have access to the wallet, even if you lose the wallet or transfer bitcoins from your wallet to a wrong address, the bitcoins cannot be retrieved. If once the block is confirmed. so you have to care your bitcoin yourself. otherwise you will lost your bitcoin for lifetime
