If you accept cryptocurrency you don’t need to do any of this, and not even deal with PayPal (who WILL rob you without a second thought, as has been well documented on the internet for MULTIPLE decades at this point).

I would like to (Bitcoin Lightning only, with a healthy convenience discount) but I'd have to move off Hetzner for my servers because they are really against crypto in a very vague way, and again, that's a lot more work than just using itch.io
