This is a legitimate btc hash miner, you cannot actually make money from this but it finds actual hashes and tell you if you really mined a bitcoin. There will be a message that tells you if you get one which the chances of you actually finding a btc block is extremley low, almost impossible. will try to make some updates. yes its prettly slow but it is scratch//
