Why are we always debating this topic. In general, everyone has the right to their opinions on the money they get from gambling or promoting gambling sites. If it's personally wrong and it's dirty money, then leave it and stay away from gambling and find a better way. So here, every opinion is kept and we are good and have the right to do it, then do it.
Well, yes that is your own opinion and I will not debate you on that matter. The fact gives me some reason why did you say that gambling is dirty money and that is wrong. Are you committing crimes on gambling? Is gambling prohibited in your place or even in your religion? Then, if yes. No doubt that is dirty money but if none of the above. I did not see that a profit from gambling is dirty money. The fact that all of these are superstitious beliefs.
