My friend is really into draftkings betting. He would spend his entire week finding and making teams, to the point where he refused to do anything else. I've told him to stop and find a job, but he doesn't seem to want to. He doesn't do that well either, and he's spending his only savings on draftkings. We are both 19, and I can't force him to do anything, but I really want him to stop. What should I do?
