I know Nostr is 'separate from Bitcoin' and everything, but they are quite entangled. Zap functionality, yes, but paid relay monetization will prove to be pretty big. Credit Cards would be a real hassle, although accepting them through the appstore would be the route that makes sense. That is making the big assumption app stores won't ban clients/have specifications on a restricted Nostr experience that is deemed 'acceptable' for the masses. Maybe apps will have two versions as there might not be too much difference in code between the versions. Upcoming Bolt 12 may enable recurring payment functionality on Bitcoin, for monthly plans of unrestricted Nostr use. The future is orange and bright, as Bitcoin now has a way to communicate online, whether that means replacing Twitter, Facebook Marketplace/Craigslist, Github, even coordinating coinjoins. The future is indeed orange and bright.
