Your debit card activates and acts the same way when it is used with a cryptocurrency merchant.
A card lets you spend your cryptocurrency with vendors you trust. A certain percentage of each purchase goes to the vendor and a certain percentage goes into a private wallet for you so it's easier than ever before to shop with Cryptocurrency. You can use your crypto cards for ATM withdrawals. If your service provider supports them, we make it easy to convert the money you put into our card into cash and spend it wherever you want.
One of the main differences is that a debit card has cash pre-loaded and the transactions are paid off later, while a credit card's transactions happen immediately.
