This usually starts when someone looses his money/BTC in a gamble it happened to me once, I loose a couple of btc then I lost all of them trying to get back what I lost on the previous game. Never do that!, in gambling you have to learn to be contented, and to not gamble with your feelings, gambling is an easy money, but it can also cause you to loose them all
It's common knowledge that attempting to recoup what has been lost in gambling has plunged many into addiction and so i strongly speak against it whenever i get the chance because in that state of trying to win back you don't think too well and often make mistakes because you loose your cool head.
