Solid post that brings up some interesting points I would like to expand upon. Volatility: Steem dollars are not volatile, but Steem the currency definitely is, more so than Bitcoin in fact.
On Bitcoin not being the winner: Right now hardly anyone has heard of Steem, I think it is great and does add an awesome "Layer" that will get people into cryptocurrency, but to imply that it will overtake Bitcoin is basically irrational exuberance. We are all in a little Steem bubble here and we have to realize the amount of developers, huge institutions, time, and money that has already poured into Bitcoin. Also right now you need Bitcoin to purchase Steem- that says a lot right now. So I appreciate your post and its points and I think people should be very excited about Steem, but we have to keep a level head about this thing also. Keep spreading the word and doing a great job.
