The exchange rate offered from fiat to the cryptocurrency on the transaction is controlled by the liquidity provider such as MoonPay. It covers the risk of market volatility from the time that the user completes the payment transaction and receives the cryptocurrency and the time it will take for the liquidity provider to receive the fiat currency from its service partners and then convert it back into crypto again for the next purchase transaction.
To put this into perspective, it can take several days and sometimes up to one week for the fiat payments to arrive in the bank account of the service provider, and by this time we all know that a lot can happen to the price of cryptocurrencies.
This is one of the many reasons why this service is so great! GokuMarket users can enjoy purchasing crypto with credit and debit cards in just a few simple steps and receive their cryptocurrency of choice in their wallet within 30 minutes.
