Crypto trading has more downsides for addicted gamblers, IMHO. There are many ways to find out alternative methods but addicted gamblers can deposit their whole crypto portfolio in one night to chase big wins, it is not a secret for us. Pro sides are there as well but I think cons are more than pros for addicted gamblers on online crypto platforms.
I can confirm that, like one of my friends did something like depositing all his bitcoins into a gambling website and went all-in. Luckily, it was an easy bet so he won. However, I immediately asked him after to not to do that again as what if he had lost all his money on that small bet? The odds were 1.2, but even with those odds losing would have left him feeling depressed for a long time.
I believe people should think more wisely before engaging in such risky bets. Losing all your savings can lead to severe consequences.
