If you quit that's when you lose is the loser mentality, in my opinion. So many gamblers have lost life savings before on gambling to chase losses and that is how they thought about quitting gambling. I don't recommend applying this logic since there is no guarantee the next big multiplier will save all previous losses while you can add up more on the loss side. Gambling is all about the fun and nothing else, so forget this point of view and don't chase losses.
