1. Similar to bigo live, instagram.
2. Payment gateway to be integrated.
3. Content creators should be able to post pictures/videos.
4. To access the content, subscribers need to purchase credits.
5. There should be multiple options to buy credits. For eg. to watch one video there should be a separate payment option. Likewise a separate payment option for monthly /yearly subscription.
6. Also, if no content is available, there should be option to refund credits back to subscriber's account.
7. Feature to pay tip on the posts.
8. Content creator should be able to live notify subscribers about live meetup..
