He's trying to use a martingale method. You can earn pretty good money with this system. Just double your bet if you didn't win. When your coupon win you get more money.
Until you get 30 consecutive losing bets and go bankrupt. Been there and tried that.
30 consecutive losing streaks?? with sports bets of 1.3 odds?? I dont think thats possible.!! If it is..that dude must be the most unlucky guy in the world.!! Anyways this is not like dice.. Everyone makes educated guesses...its tough to even reach 5 in a row..if u r skilled.!
hold on. he is doing parlay on 1.3 bets to get to the 2.0 odds. One of the parts of parlay is wrong and the whole bet is wrong (see example from post #2). That is not very unlucky. And not very unlucky he must be, to have series of consecutive parlays that go wrong and wipe him out on martingale.
