stick with what you know (I think) the crypto world is full of good ideas and some excellent projects. If you want to explore some feelgood I'd recommend having a read about gridcoin, curecoin & foldingcoin are all very interesting, because they all do something very positive. as does einsteinium. Trading is tricky. because it's unregulated and quite a small market, it's obviously subject to manipulation so a few people make a lot of money. unless you really know what you're doing, (and have the time to dedicate to it) trading means you're probably giving your money away, but long term speculators may have something good because as bitcoin rises it will take many coins with them ¬!
