Before creating your first order, we need to know a bit about you. As a financial service, Coinmama is committed to the highest security and privacy standards.

Since there is no central bank controlling cryptocurrencies, it's important to understand that each provider chooses its own rate. However, to help keep things clear, services like TradeBlock XBX list an average (or market) rate based on the known providers. Coinmama's market rate is based on the XBX + 2%. In addition, there is a commission fee of up to 3.90% on buy transactions and up to 0.9% on sell transactions. For credit/debit card transactions, we add a 5% momentum fee. For transactions made by SEPA bank transfer, there is no additional fee. For transactions made by SWIFT bank transfer, there is a minimum fee of 20 GBP on orders below 1000 USD and no additional fee on orders above 1000 USD.
If your payment hasn’t been approved yet, the charge you see on your account is probably only an authorization check created immediately after a payment attempt is made. This is necessary to "save" the transaction amount in case the payment is approved. If the payment is declined, the charge will automatically void within 48 hours, depending on your bank’s policy.
Our rate is displayed in USD, EUR, GBP, CAD, AUD and JPY, but we accept all currencies. Note that if you pay with another currency, your bank may charge an exchange fee.
