I feel that I am a realistic optimist. I hope for the best, but have been around long enough to be a bit jaded and to not expect too much I guess.
I am optimistic about Steemit. I think the developers really make something that broke the mold of the traditional reliance upon advertising.
So what can go wrong....Some things are outside of the control of Steemit. One problem would be heavy government regulation. Also the whole house is built upon the value of the coin. That is what to keep your eye on. I hope you get to a mil!
