Now the point here is that on the gambling site, there are many easy winning bets with odds like 1.01x etc. If the money lauder is sensible he can easily be wagering the whole amount by placing a few bets where the odds are very low and the winning chances are 99%.
So does this mean that there is a loophole here and the money launderers can easily by pass this wagering requirement?
It's not really a loophole, because you still have to bet your whole balance a lot of times (maybe 100x times at 1.01 odds) to fulfil the requirements. There more requirements than just betting your full balance only once, some websites have minimum odds of 1.5 to bet on and other require you to fill up a bar of risked money where you would need a lot of bets if you only stick to low risk bets. It's been a while since I got a new bonus, so I am not too familiar what the industry norm is right now on clearing the withdraw restrictions. For me it was always combi bets that I used to combine multiple low risk bets to make one higher risk bet to clear bonuses. The problem with placing all your money many times on these low-risk bets is that there is no guarantee it's going to work. Only missed bet where the favourite plays a draw and not a win, is enough for you to lose all your money. It's a huge downside risk that I would rather avoid, because its more likely that in 100 games something will go wrong.
