Coinbase sent an email to some customers early Feb. 1, alerting them that credit card networks are beginning to treat cryptocurrency purchases as cash advances, leading to fees and higher interest rates on these transactions.
A Mastercard spokesman told Investopedia via email, "Over the past few weeks, we have clarified to acquirers – the merchant's bank – the right transaction or merchant category code to use for these type of transactions (cryptocurrency purchases). This provides a consistent view of such purchases for both merchants and issuers."
A Visa spokeswoman said via voicemail, "it would be up to the individual issuer, the financial institution that issued the card, to determine any fees that they might charge for certain types of purchases, so it's not Visa. We don't issue cards."
