f2pool supports manual withdrawals if the balance amount of an account is no less than 10% of the default minimum payout threshold. For ETH, the threshold for manual withdrawals is 0.013 ETH.
Manual withdrawals are available for most coin types on f2pool. However, due to transaction fees per network, f2pool will not proceed with withdrawals to accounts with balances below the threshold.
