I am building a game with in game purchases. I want to minimize my reliance on fiat systems as much as possible, but I want to be able to accept fiat. So I am looking for a payment service which would allow users to pay money fiat which gets credited in game and instantly paid into my cold wallet which can be any major crypto I don't care.
Does anyone have any experience with a service like this. Obviously I am looking for good reputation without too much regulatory overhead, minimal compliance obligation, low risk of getting shut out for some made up bullshit? I am asking here because Monero people might have experience and a reasonable appreciation of these priorities.
In case you're wondering no its not a gambling game or anything defi, I just prefer no banks n shit. The money pays for premium membership and skins.
