The main issue is that you can't go shopping and pay for your goods with cryptocurrency or crypto rewards as most merchants are not ready to accept the crypto. You can face this problem in a local bakery or a big shopping mall - doesn't matter. You will have to convert cryptocurrency to US dollars before you will be able to shop. And that means conversion fees and taxes you might not be ready to pay.
Of course, more and more places are going to legitimize cryptocurrency as a valid form of payment in the future, but you need a card to shop now!
For your everyday shopping, a traditional cash back credit card can be more appropriate because you can shop everywhere and get simple and straightforward cash back every time you make a purchase.
