Donation/small payment situation for small artists/content creators is abysmal. You're forced to one of the following:
1. Offer multiple choices for payment => people need to sift through to find what works for them and give up after first fail.
2. Use a payment [processor] aggregator => unreliable (as with this case) and takes a cut (sometimes chained).
3. Use crypto only => the only thing that works reliably, but severely cuts your audience to those comfortable with it.
