Millions of bitcoins are considered lost. Who will find them?
Brute forcing private keys is hopeless. What might be possible is recovering bitcoin from wallets whose passwords have been lost if the wallet file is retained, if the passwords are not too difficult to crack. And there might be bitcoins considered "lost" because the original owner has died, and whomever inherited their equipment has not noticed/found/deciphered their bitcoin wallet setup (or paper wallet tucked away somewhere). There are varying degrees of "lostness" to bitcoins that are considered lost.
Lost means many possibility, forgot password, long inactive account(usually forgot wallet), or owner acct has died.
that's why private keys creates to makes it privates, its different from password. when u lost it. Schvey said "This is what the security of Bitcoin is actually based on. If youve lost your private key, the system is so secure that you may not be able to recover it."
So it is impossible with regular resource to find them.
