Or should I discourage him by showing him videos, articles, and testimonials?
Because of this, I will not talk about online gambling to newbie I could put a guy in big trouble.
It’s too late already for this guy to be stopped since he already experienced the taste of success on his first try. Martingale is really dangerous but sometimes it works on giving successful run on gambling.
I’m not sure how you can convince him anymore to stop gambling even using other testimonials about how dangerous it is because he already has the successful thoughts on his mind. Maybe your best chance is to convince him to just lower his bankroll because there’s no way to completely stop him. Only the experience of losing will gonna teach them the danger of gambling.
