The Bitcoin mining pool Foundry USA Pool recently showcased its 'warm-hearted' side by refunding an unexpected transaction fee of up to $777,000 (8.18 BTC). On December 19, Foundry mined a Bitcoin block and found that a transaction fee was 91,127 times higher than the necessary fee! After careful consideration, Foundry decided to refund this fee to the sender instead of allocating it to the mining customers of the pool. It is worth mentioning that this is not the first time a mining pool has refunded high fees due to unexpected events. Foundry's hash rate is currently about 280 EH/s, nearly double that of its competitor Antpool. 🔍💰
