According to Wu, Bitcoin mining pool giant Foundry USA Pool returned 8.18 BTC (about $777,000) in mistakenly paid transaction fees.
The fee was paid by a user by mistake on December 19 and was 91,127 times the normal fee.
Foundry said that after careful consideration, it decided to refund the handling fees to users, and emphasized that similar situations will be handled on a case-by-case basis in the future.
