Nice to see an objective analysis of this platform rather than just blind support.
I'm also following the "keep on to whatever you don't mind losing strategy." This platform could boom just as easily as bust, but I'm guessing we'll see ups and downs for a while before anything definitive.
This reminds me of biology. New habitat, new environment. Fast speciation, many of them will disappear, other will evolve.
My vision: the best known will survive and those with the large community around. Other very specialized coins without some exact purpose, copies and sufficient base will go down to oblivion.
STEEM is in the promising category. With the development of some new interface - it's possible to see the rise in popularity.
