Hi, It's not a 'scam' at all. It's business. They aren't giving you free money. You watch advertisements (like 3 per day) and they pay for that. Plus you can, if you want, use their traffic exhange to even get hits on your own sites. It's all legit. I haven't invested any money yet as I am still in the procedure of getting some extra money saved up for it, but the free $10 is good to get started with.
