I agree that cryptocurrency cards are the money of our future. Take a situation where you need to go to another country. First, you change Fiat to the local currency, then back. So much time spent, so many commissions. A cryptocurrency is universal, it solves the problem of exchange in a few seconds. And there is no doubt that credit and debit cards for digital assets are distributed throughout the world.
it is not the future, but already the present. I heard that the PayPal allowed the use of cryptocurrency. Which means that each user of their service can pay with a crypto through a paypal card.
