I'm all about the rise of cryptocurrencies and alt coins, but I still believe diversification is a good idea. We're dealing with some pretty new ideas here and-- in terms of overall development-- the playing field has barely been defined, yet. I'd like to know (for example) that I can run down to the market and buy a loaf of bread with Steem as a part of regular existence. I'm sure that time will come... but until then, this is an intriguing but somewhat speculative investment. But that's just me.
