We have just launched our first GPT website, we share our profits 50/50 with our members. We have offer walls, PTV PTC, PTSU, and premium ad slots. Come and have a look. We pay out in BTC but it must be requested via forums, or support request currently.

I think 50% share is very low if compare to other gpt site. Most of them share 70% up to 90% to attract user.http://cpa-coin.com
So you need unique features for user or they won't joint with you
If you actually compare other offer walls on the web they are only 25-35% but thank you for your input.
