1% House edge is typical nowadays but actually when we do talk about profiting matters it would be all in random as said we wouldnt know if they
lost or win on such wagering contest and this all matters with luck.We know dice that it can give out profits or negatives randomly or without precise
assumptions.
That is why I am supporting smaller bets, if they martingale they can literally go 10-11 times in a row loss and still make it back with the amount they have, now if you want to "profit" then you may not do that with martingale we all know that, you can end up reaching max allowed bet at some point, however if you start low and keep gambling for hours on autobet with unlimited account and stop when you reach the top of the list you can stop and not lose money, in fact even make money.
Yes, there is still a chance of losing a ton but at least it would be a bit more possible since there is a limit how much you are going to play and stop before you end up losing all your money, if you do martingale forever eventually you will lose but if you set a certain stop there is a higher chance of winning.
