The future of credit/debit cards of cryptos will come from the cryptos itself. We can't expect VISA and MASTERCARD to fully support bitcoin and other cryptocoins. I am willing to use some card as a payment method to use my bitcoins in all over the world without this bureaucracy called "fees and prohibitions".
This is very bad because there were lots of projects working on crypto debit cards. We can count Monaco Card, TenX, Token Card, METAL pay and a lot more of them. They're million dollar valued companies now.
