If you wanted to take a bit of a risk then I think you can try to invest on a potential new project.  Project that has a solid development team, a working business model and yet to be exploited by pump and dump people.  It is somehow hard but if you happen to find one, you can then enjoy a possible 100x to 1000x profit in a short span of time.  Might be longer but not as long as 2 or 3 years of waiting.
