Except for ETH, f2pool does not charge any transaction fees for paying out mining revenues if the balance is above the minimum payout threshold.
For ETH, since the mechanism of ETH transaction fees has changed, we now charge 0.001 ETH per transaction as the fixed fee.
You may pause the daily payouts and let the rewards accrue in your account, then resume the payouts when you need, or change to a higher payout threshold in your account settings, as ways to reduce the transaction fees. On the other hand, you may also use a Loop wallet address which does not charge any transaction fees for f2pool payouts.
There will be a fee for manual withdrawals if the amount is below the payout threshold.
Since some platforms charge fees from deposits, miners should contact their payment receiving platforms if the payout amounts differ from the receiving amounts.
