So basically, you are saying that poker tournaments where you can win a huge amount of money is dirty money? well if I am the one who's gonna win, I dont mind having a dirty money, I gamble my own money to achieve that. We all have different perspectives, I'm a gambler and I dont think that this is right.
You also don't have to mind people who think that way, that's kind of a stupid thinking.
They are judging in general that what you earn in gambling is a dirty money, and its also possible that the way they look at gamblers, they look them as criminal. Well, let them do the judgement, as the saying goes, you can't please everyone and only those who are close minded are usually not gonna make success in life financially as they are afraid of taking risks.
The majority of society makes money by normal jobs, anything like, street vendors, secretary, cashier, etc. and they don't see gambling as a way to earn legal money. The Government is against gambling casinos who doesn't have any legal papers, so earning money by gambling means dirty money to them, but it does make sense because if it is illegal, then it is dirty, it doesn't matter hoe much you are winning because it is dirty money for them
