Sure, but banks don't make money on credit cards if we pay our bills in full at the end of each month. They make money on the interest when people pay less than the full amount. I don't agree with it and always pay my credit card bill in full at the end of each month, but if the bank is happy for people to max out on their card for a widescreen tv, to intervene when they are maxing out on crypto instead is not letting people spend as they wish.
