Pool fee refers to the charge that mining pools impose on their members for participating in the mining process. Mining pools are groups of miners who combine their computational power to increase the chances of successfully mining a block.When members of a pool contribute their hashing power, the rewards from mining—typically new coins and transaction fees—are shared among participants. The pool fee is a percentage deducted from these rewards as payment for the pool’s management and infrastructure.The fee can vary between pools, usually ranging from 1% to 3%. Some pools may have a fixed fee or structure the charge differently, such as through performance-based models. Understanding pool fees is important for miners because it affects overall profitability. Comparing the fees of different pools, along with their payout structures and reliability, can help miners choose a pool that aligns best with their earning goals.
