Bitkub normally collects Cryptocurrency withdrawal fees in each transaction made. The withdrawal fee on Bitkub will be referred from the fee on Blockchain. It can be adjusted at any time in order to correspond with the fee on Blockchain and to increase the capability of our service.
If the fee needs to be reduced or increased significantly, we will update the withdrawal fee accordingly at 00:00 and 12:00 GMT+7 every day (if any).
