I'm good in sports betting because of the familiarization of the sports and what team should I bet with. 80% of the time I win rather than playing with dice games I'm not good at it.. should have pure luck to win that game.
I am actually good in dice, since it gives quick results its easy to implement and check my strategies.
Earlier I tried with 1.25 payout in dice and it worked for a long time for me ( yep, made nice profit ) then busted it, but well at least I got to some significant amount, which with sports I never did.
