Yeah , i have tried it many times also. During last Cricket season , i soend almost 5$ everday and luckily i made 8-9 $ everyday from it . Its gambling only , If you lose , you lose everything so never invest everything, just take it for fun and invest very small amounts , its best.I know that bookmakers make money through betting. Because they set the betting markets, options to choose from. So when people make losses they gain as well. I strongly believe that bookmakers earn enough money by hosting betting platform. But I haven't seen a bettor amazing huge sum of money through offline and online betting business. Have you seen any one that made cool cash through betting system??
