The #DolphinCard has a 1% fee but you maintain full privacy & sovereignty. Other cards might pay you 4% to use them, but you have to give up all your info, let them track your spending habits, and sell your data. They can de-platform you anytime too. I know which one I prefer.

If you're getting paid to use something, you're the product.

If Coinbase is willing to give you back 4% then your information is probably worth something like 6-7% when sold because they are making some profit in there too.
