Bitcoin Miner AntPool to Refund

AntPool said it would verify the identity of the sender if they sign a message on chain through another Bitcoin transaction using the same message, which will prove ownership. Last Thursday, AntPool received the standard 6.25 Bitcoin (BTC), as well as 85.2163 BTC in fees for all transactions included in that erroneous transaction, on-chain data shows. The sender's wallet was set up just minutes before the transfer and the recipient received only 55.78 BTC of the original 139.42 BTC that was sent.
