This is a follow-up question to: What happens if I mistype the address when making a payment?.
- You're trying to send bitcoins to an address.
- You type in the wrong address, but the address (as unlikely as it may be) is well-formed.
- The wallet belongs to someone and you've just sent him money. (Can one contact this person and ask for it to be returned?) The key phrase is "can one contact" not "can you force him to give it back."
- The wallet (as seen in the quote below) is unowned and the bitcoins are lost!?!
Bitcoin addresses contain a built-in check code, so it's generally not possible to send Bitcoins to a mistyped address. However, if the address is well-formed but no one owns it (or the owner lost their wallet.dat), any coins sent to that address will be lost forever. https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses
Is it lost? Or, if and when, this wallet is created are the "missing" bitcoins attached to it?
