huh? visa pays me 2%, not the other way around. I don't pay 2% more when I use my cc instead of cash, rather, I receive rewards. You could claim that the grocery store has to increase prices due to the fees that visa charges them, but I think you'd be wrong: visa provides a service that is cheaper than the store handling cash (security, transportation, slower transactions etc). Visa also provides a service to me, which is that if someone steals my card and buys groceries, I can get my money back. No crypto system will ever support that.
