If you've previously verified your identity, yet are being asked for verification again, the reason is most likely that you've exceeded your current KYC limits. That means we need further verification in order to push the transaction through. For example: if you've been verified through your bank and make a transaction of 5000 EUR, we will ask for your ID or Proof of Address in order to ensure the transaction's safety. Please note that the KYC limits are for reference only and depending on the risk of your transaction, we might ask for additional verification on various stages.
