There is a site where you can bet on sports without losing money. I use it to pass time when I don't have a fantasy sport going on. The site is http://www.centsports.com/?opcode=518551. I have been on the site for abo0ut 6 months now and it seems legit. They don't send you any emails or spam. You can even get your winnings in cash supposedly. I, unfortunately, am a crappy better so I have not gotten up to the $20 min win yet for the payout.
