Since there is no central bank controlling cryptocurrencies, there is no single entity that controls the value of Bitcoin. At Coinmama, we take the average rate amongst major exchanges and add a spread to account for market fluctuations. We refer to this as the "rate".
For buy transactions, we charge a commission on top of the rate depending on your loyalty level.
Additional fees may apply if the rate is locked until we receive the payment. If your chosen payment method requires a locked rate, you'll see this as a 0-5.00% express fee during checkout.
For sell transactions, we charge a commission on top of the rate depending on your loyalty level.
