You can start an E-Money Institute in the EU and get a license to issue a stablecoin under MiCA.
I looked at the laws and there is genuinely no way to earn money except from the difference between the interest payments you get on the custodial accounts (at a normal bank). The only exception is if the contract contains an explicit duration. Then you are allowed to charge a "reasonable" fee for trade ins to Euro. E-Money is not allowed to pay interest. It is basically irrelevant unless you want to do a radically different form of banking.
