Being paid 0.05 or 0.10$ by a user.

Hi,

I would like to add a service to my website. This service needs GPU and I have no money to invest now.
I could manage the cost if each user who uses it pay 0.05 or 0.10$.

Paypal would be great, but the fees are too high. And so are Stripe, Cash, ...
Some countries have no-fee solutions, but it depends on country and currency. I would like it to be usable anywhere.
Crypto would be the solution, but my visitors are not the kind who know how to deal with it.

Do you know a service I can use, which is easy to use for very small amounts? Maybe something like a mega-rewarded-ad?

Thanks,

You can use crypto; there are coins with low fees.
