Forex. Is it worth it?

Making money from money? I wouldn't. There's no deep philosophical meaning in it, and its practical usefulness is questionable. Besides, it's unlikely to be that simple; you need to have a more or less good understanding of what's going on and ideally have some experience, otherwise, it's not a given that it will be profitable. Even on the wiki, you can read about the risks; I don't know how accurate that information is, but it all seems logical.
