Hi Guys! I've been into sports arbitrage also. Sports arbitrage is a technique wherein you take advantage from bookies. It is really risk free but you have to be careful in placing your bets because arbitrage is something that you can't master overnight. It takes a lot of time and effort also. But I've found a blog which can actually help you with sports arbitrage, try reading his blog, bestarbsportsarbitrage. wordpress .com, very informative and it is easy to follow. I've learned alot from his blogs. Thanks!
