I am a sports fanatic and follow a lot of different sports. Although it's not a PTC site, it still gets you cash, and depending on your luck or sports analysis, LOTS of it. CentSports is a FREE sports betting site. How it works is that you automatically start with 10 cents in your account and you are free to bet on whatever sport thats available. If you lose your money, then CentSports automatically deposits another 10 cents into your account.
