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

In my opinion, the key is to focus on user engagement and offer value before considering charging for your mini app. Consider different payment options to cater to a variety of users
