Coinbase had previously announced to its customers that several large US banks had either changed the way they were
processing credit card purchases of cryptocurrencies or were banning their cardholders from using their credit cards to purchase cryptocurrencies.
Several research papers have shown that a relatively large portion
of investors in certain regions that use
credit cards to
purchase bitcoin and other
cryptocurrencies tend to not
process their
credit card payments after investing in the
cryptocurrency market.
