Instead of a serving ads, Portal allows person-to-person payments:
1) Everyone can send Coins ($0.10 to $100) to instantly support what they are watching. Just tap the heart on any piece of content. Coins can be purchased in the Portal iOS app.
2) Everyone can optionally add a price to what they upload. Charge $0.01 to $100 or keep it free.
Coins received are automatically converted into USD and can be cashed out to PayPal.
3) Send and receive monthly recurring subscriptions.
