Gambling is an incredibly strange thing, where both the fear of losing money and the chance to win a lot of money are combined. And the same thing happens with human emotions. Many gamblers come there to relieve stress, but in fact, they get even more stress after losing.
And, of course, such people are led. They hope to earn easy money, or hope to win back the money they lost before, but, unfortunately, most of them will end up with new disappointment.
Anyone that wants to relieve stress with it should follow the right principles and they will do just fine. The reason so many gamblers get trapped is because they did the opposite, they used the money they were supposed to use for something else, they use it to gamble, they put too much hope in multplying their money and that's why they end up being stressed at the end.
