This site has 3 separate branch sites that earn 1 point for viewing 20 second videos/ads.
Each point earned counts toward a percent in a shared member pool and a chance to win prizes such as .10-.30 BTC and a $25,000-$100,000 car. Payout is every week and there's even a widget that displays how much some members are earning
per week. You'd be surprised to see how much it is!
