When I discuss the wide range of gambling and betting with friends who are not on the forum, I often notice their flawed thinking. If it were just once, I would not have given it a thought but when their flawed thinking about gambling comes up over and over again it makes me torn between wanting to help them change the way they think or just leaving them to continue with such thinking until some major gambling experience happens and changes it for them. Some type of this flawed thinking is borrowing money from loan apps to gamble thinking that when they win they will pay back the loan and its interest and keep the rest for themselves. They call this gambling, with other people's money. Another flawed thinking is their belief that paid between groups will make them become millionaires faster than if they are not in the paid group. There are others like this.
Lol, such mindsets need total overhaul to be honest, and one thing with gamblers with such mindset is that they will hardly listen to you if advicing them, most especially if it's people that you are better than financially, some of them will think that you are only advicing them not to engage themselves in such things simply because you have money yourself and don't have to borrow, so you possibly don't understand their predicament or that you are not in shoes so you possibly don't understand...
Like you said, it's sometimes or most times best to simply allow those with this type of mindset to do what ever they really want to do, possibly with time, they learn their lesson the hard way..
I used to have a friend who loves borrowing money to gamble, even when he has his, he will still borrow money and only pay back that money when he wins, if he doesn't, he will refuse to pay back the money, he did this until everyone knew who he was and started avoiding him, one time when he ended up in a very serious problem, no body could help him because everyone assumed he was lying that he will use the money he was looking for to gamble and will lose it and refuse to pay afterwards, he ended getting arrested and he spend 7 months in prison for something a few hundreds of thousand in Nigerian naira would have sorted out.
