You're imagining it's as simple as doing the thing and walking out with bags. But it's actually just a market. Most participants in most markets struggle, regardless of their morals. It doesn't matter what news stories you read about stupid actors in a market: most are actively trying to make smart moves, and as in any chess match, it takes some special insight to get ahead. If you get chewed up and spit out, that would be the default result.

So yeah, go try it. "Don't spend more than you are willing to lose".
