These basically all fall under gambling. These aren't the best ways to make money, and they sure as hell aren't the only ways. I'm not sure why you didn't put real options on there such as actually getting a job, freelancing, doing tasks, etc. If I had to choose though, I'd probably go with trading because it's one of the only ones there that gives you an actual chance to make some money if you study hard enough (plus if you have luck on your side)
