I know what it means but have no idea how profitable it is or whether those profits are guaranteed or fleeting. Best I can tell it's like any service (business, not investment): depending on demand and competition, you can make money for a time, then stop at some point. So far that has never been an issue for people investing in the global stock market (i.e. the global stock market persists even as individual stocks, sectors, industries, even whole countries have crashed in the past).
