I have to say I'm personally pretty allergic to fees. Even Stripe's fees are above what I really feel comfortable with, but I'd probably pay those to deal with payments less. Anything above 1% and I'd probably be out, to be honest. As an alternative to a fixed percent, I'd feel a lot better about a model where the fee gets progressively less with a larger amount of users. This may or may not be a personal thing.
