Huh you say that they can make money on gambling? it seems that you really convince them to gamble if they want to make money, honestly it doesn't make sense, how can you say something that is uncertain and does not guarantee with great certainty? this is the wrong mindset and is not recommended for anyone who wants to enter gambling, if you bring the mindset and assumption that you can make a lot of money just by gambling then I say it's like you dig a hole to trap yourself.
Don't let your brain and thoughts run dominated by lust, because of course the casino will not easily give you a win unless you sacrifice a lot of money first then the casino will give you occasional wins of a certain amount and if you I'm sure the amount of your losses is still very large. Honestly, I really don't understand your statement, let's think logically and accept the real facts which have been proven and many people have experienced large losses. You must understand that gambling is nothing more than just a fun activity because the final result always depends on how lucky you are during that session. So it is not recommended to bring in a gambling mindset to make money if you don't want to get hurt, unless it's just for fun.
Making money in the gambling was not the easy one,you should have the luck.So the gambling sites algorithm will match to your algorithm,it's easy to win the game on the lucky time in the gambling sites.But many gambler was not ready to accept the fact that the gambling was based on the skills.The thoughts always dominated the command from the brain,the gambler thought was over come by the command from the brain.This was biggest reason the gambler was advised to get some trips after the loss or gain in the gambling sites.So the gambler will get the clear mind set,this help the gambler to prevent from the continuous loss in the gambling sites.
