When I travel, I really like that my crypto debit card supports multiple currencies. Usually, it uses the local currency if you already have some on your card, but if not, it instantly converts your crypto to whatever you need at the point of purchase. You can see all your balances in the app and sometimes even switch your “main” spending currency. I found more info and tips for managing it all right here:
