This is a website that lets you bet real money, without spending a dime. (The advertisers pay for the the money that you bet with.) You start with 10 cents, and every time you go back to 0, you get another 10 cents. Eventually you can turn that 10 cents into $1000's, just like any other online betting website.
By inviting a friend to Cent Sports, you also make 5% of what they make, (NOT of their money).
Its free and it doesn't require confidential information like credit cards,bank accounts or socila security cards. Its not a scam. They pay in US funds.
