Have you tried Patreon (
https://patreon.com/kevinhearn ) or one of the Crypto Currencies?
To quote Kevin from another thread:
Currently there's no other options I can offer aside from PayPal and Patreon and crypto. I've been looking around a lot for better platforms, but some of the other services have big fees for certain things, some don't work from outside USA, and others are just front-ends that still require everything to process through PayPal or Stripe anyways.
But regardless, thanks for trying ;) The fact that people are willing to help me keep going with this software is motivating.
