Commission is charged for manual withdrawals, as they are given high priority and will be added to blockchain very soon. You can also configure Automatic Payout to be sent to your address when the balance is above the threshold (default is 0.01BTC.) Please go to your Profile settings and see the Auto-payout section to configure this feature. AP will be triggered once every 24 hours, and there is no fee or commission.
