I've had a few instances where I've won by betting everything. But in other cases, those wins outweighed the losses. You can't win all the time when you bet everything. Or the winnings in those cases have to be astronomical. So whether it makes sense to bet everything because of the low probability of winning is for the player to decide for himself.
As long it would outweigh the loses then it is really just that fine but you should really be that making yourself that still having that kind of moderation when it comes to this kind of behavior because we know that we cant really be lucky forever and this is why if you have seen that you are already breaking even with those loses with your wins then this is the best time for you to stop completely this kind of decisions.
Betting on last cash you do have is really that something that you will really be having that kind of approach when you do see that it would really be your last bet.
Its a common reaction i should say because im really like this on the time that i have that last drop of my bankroll because on this particular time or moment, you would really be having
that kind of thinking that trying to make that all in on your last bet, so it would really be that depending whether it would be a winning or losing bet in the end.
