Your friend at this point dont need any advance, he should learnt from the experience he got in the process. Whenever you lose as a gambler you dont chase after loss, the moment you start to do that, you will most likely lose everything.
I think if you call it just “
an experience” is kinda undersells mate. it not seems anything harmless to me, although he didnt spent too much time on it but it seems very serious gambling disorder to me even more than sports betting/casino betting, spacially when he is very young guy. seems it is no longer at that level, like
just a lesson learned, real harm is awaiting. Yeah you could say he is no longer in it quitting is huge however such shit runs deep. i think this friend could not go through a learning curve, he really needs tools maybe therapy or support group.
