Everyone can follow all kinds of cautions before gambling but when one starts gambling the gambling algorithm makes him sentimental. And at that time he forgets all this. Everyone knows that gambling should be done only for fun and not to increase one's financial status, but almost everyone forgets this while gambling. So although these tips are common and for everyone, they don't work for most gamblers. But if one follows them then one will surely be saved from many harms. Gambling is not bad but it becomes bad when it starts ruining someone financially and he continues to gamble without caring.
yeah, the problem usually begins when someone makes a big win (or see someone else`s big win). Then the idea of easy money and quick rich scheme makes most people decide to take enormous risks.
I see the same behavior in memecoins market, which is basically the same as gambling (maybe better odds)
