Like I would always say, the best way to enjoy gambling is to lose the money before you actually lose it...
That is, if you budget that you are going to gamble with $50, then even while you have not started gambling, consider that $50 lost before you actually lose it, this will help you relax your mind if eventually the money is lost in the course of gambling, one thing that causes depression and anxiety is expecting to win big amount of money, which if not won at the end of the day, would cause the player to become disappointed and angry with himself and those around or her.
This is indeed very funny but, it would work and in the event that you even win, the joys would be much while, the lose would make no meaning since the money was already lost.
What this simply means is that, the money your betting with, is a money that your ready to lose and that's the right attitude.
Looks like op got screwed by placing a lot of winning bets on smaller leagues which is why his proposition could grant huge rewards, but it could also screw your accounts up which is why it isn't advisable.
It's better to gamble on your own instead of adding in this extra layer of risk in my honest opinion.
Possibly that could be it and it did hit me just now. I recall some compliants from a user sometime last year when his wins got frozen on Fortune bet, I think the issue was on repeated bets on same events. Hence, OP having his or her account frozen won't be far from a term being bridged as, there isn't anything wrong with winning.
