those who have religion will say that it is dirty money. Well, this response has been around a long time ago. but, many people have hobbies like that and ignore them. even in my place, when you are caught playing gambling, you will be violated by the law. but, there are still many who disagree with it, many of them say that gambling is not a dirty money. I can only draw the conclusion that many people have different opinions about this, depending on their respective beliefs.
If you are a law abiding citizen the you must follow what the government tells you because not following them will result for much bad outcome
If you want to gamble legally then better change place or country mate
Gambling money turns dirty if this was illegally acquired and doing this in countries that prohibiting gambling is also a dirty money
