I do agree that gambling is not a way to make money, however it doesn't change the fact that there are too many people like that out there. I mean think about it, how many people have you seen that lost all of their income and money to gambling? I have seen too many, I have even see a guy who sold his guy to bet on a sports game.
Gambling is fun and not bad if you gamble responsibly. If you can not gamble responsibly, you should not gamble because you will not be able to protect money from your wins and will lose all your life because of gambling.
With Sports, like soccer, I would like to bet with corner stats because I won't lose my feeling when I watch matches. I can enjoy both gambling and match watching. If I bet with win or lose team, and result is not as same as what I bet, I won't want to watch rest of the match.
This is the type of crazy people we are talking about and they are all around us, and during the hype periods when everyone is making money because prices went up, people who are very late to party come in here, see that everyone already made the money they wanted, and they are too late so they end up seeing gambling as a way to make money because they normally can't in their home nation. These are all wrong things, I agree, you should gamble only for entertainment and that is what I do, but just because it is wrong doesn't mean it doesn't exist.
When they win big from trading, investment, they will use more money to gamble. They will bet more when they lose more in trading or investment. It's bad that if they lose in trading, they will lose in gambling. Because they do trading or gambling irresponsibly.
