If you’re interested, you could probably convince some people to take on the risk of payment as long as you consistently pay them more. I’m not sure anyone would want to pay more like you seem to want, but sure. To each their own, I guess.
After all, that’s precisely what payment processors do: they make people pay much, much more than what it costs. PayPal and Visa are notable examples.
It’s just that most people don’t realize it, just because most people aren’t merchants paying a variable fee and a fixed fee on every payments they receive.
So, to me, it’s a non problem of a user who’s grown accustomed to pay for hidden costs. Yet it’s precisely how you can get cash back models with crypto credit cards: because it’s cheaper for merchants and they’re ready to pay a cash back to their clients as long as it means paying less overall than with PayPal and such.
