After you have selected and confirmed to withdraw, you can check the transaction record on www.btc.com using the withdrawal transaction ID.
If the record exists, it means that the withdrawal is on the way. If you are unable to find the transaction record, please raise your issue with us immediately and our support team will help you.
Under normal circumstances any coin transaction will receive confirmations quickly and the withdrawal will be complete very soon. But if there is no confirmation yet, please wait for it.
Please make sure you always withdraw the minimum amount (at least 0.001 x 2 BTC).
