I'll look into crypto. It's frustrating that there is no painless way to do this. My app is in a weird place where it doesn't generate much income/traffic for me to invest significant amounts of my time coding up payment apis, but at the same time I'd like to keep it self sustaining and payments or ads are the only real ways to go. I'm more interested in payments cause I'd like to do rapid AB testing and see what customers find valuable and what they are willing to pay for. Ads are a passive stream and don't really help me learn about the business.
