I also told him that you should stop gambling, it will lead you to ruin, rather you should invest in Bitcoin and you will achieve something good in the future. So I want to tell my community that if someone cannot profit from gambling, but rather suffers, they should stop gambling, and as an alternative, invest in Bitcoin and hold it, it is best.
You already know that bitcoin investment is best in this case but you should also know that gamblers don't admire long term profits but rather they target the short term profit because they believe in what they are seeing at the moment than what the future promises.
He shouldn't rush into bitcoin investment as there's always time but now you guys should be focused on knowing if it's an addiction or something else but regardless you guys should be focused on knowing the root of his problem and seeking solution to it.
He deserves some sort of rehabilitation to treat and examine his condition and if his in the right state then you can proceed to introducing bitcoin to him and even the forum as time goes on and that's the best you can help him do.
Goodluck
