How to charge for your mini app

1. Focus on getting people to use it

2. Then focus on getting people to add it

3. Send them notifications

4. If you can get them to come back 3x and do your primary thing, consider upselling 

5. Most basic version of payment: become a supporter

6. Other ideas: more content / features, mint collectibles, early access, group chat access for power users
