Some people actually think there are patterns in slot or dice games who probably think trading is also like gambling based on luck. Lottery for example is what makes it obvious since they are buying tickets every day with the same number over and over thinking it will eventually come and they get to win the biggest life-changing money. They wouldn't consider buying tickets risky when they spend just a dollar a day than trading which a trader will put a thousand.
What else can we do? Force these people who are not a fan of trading to consider trading compare to gambling.
Just let these people do what they want. These people who are lottery enthusiast surely knows the risks they are dealing with and the slim chance they are facing to win this life-changing money. We can't just tell them to do trading instead since if there is no interest, then they are just gambling their money in trading too, the same way they are doing it in gambling.
Instead, if we really want to help these people to change their gambling habit, give them a nice talk to put their money instead on something good that they really have an interest in and not that they just see other people making money out of that.
