If your balance dips below zero or your deposit disappears sometime after you make it, then your deposit transaction was canceled by Coinpayments. This can occur for the following reasons:
- The commission you used was too small and your transaction did not receive the required number of confirmations;
- You forgot to consider the commission during the deposit or withdrawal from the exchange (the required deposit amount does not include commission — it must be added separately);
- The required amount was transferred partially, but not completely.
If you spent the funds partially or completely in the time between the deposit and the cancellation, your balance may become negative, and you must repay it in order to continue to use the service. In this case, all open transactions will not be canceled and will be completed.
