Some of the most common reasons for an exchange to fail are:
1. Insufficient funds: the amount of funds that was we received was insufficient for an exchange. In this case we can try to issue a refund. Please provide our Support Team with a valid wallet address.
2. Invalid address: sometimes people make mistakes, and you might have accidentally specified an invalid receive address for your exchange. In this case, the exchange will fail. Don't worry - we'll be able to proceed with the payout transaction as soon as possible once you send us your correct address.
3. A technical issue has occurred during the exchange process.
Please keep in mind that in case of a failed transaction, we are always able to either proceed with your exchange or to refund your coins, depending on the situation. To speed up the process, please try to provide our Support Team with as much information about your exchange as possible.
