Confirmations of BTC transactions can have a delay for a long time. This happens for various reasons, from a small commission for miners to delays in the BTC network.
If you sent us a BTC for an exchange order, it is important that the system sees your transaction. In this case, the system will wait for confirmations, and the exchange rate will change until the required number of confirmations is received.
If you bought BTC, the transaction was created, a delay is possible only in one case - a delay in the BTC blockchain, because our system gives a high fee of miners each transfer. In this case, need to wait when blockchain BTC becomes normal.
