1% of coins will survive. 99% will perish.

Right now Steemit is the only one with a viable product along with a few others. In the area of social media is the leader. I believe Steem will survive and get adopted widely. Heck, even other social media sites can borrow the scheme.

As for Steemit the platform itself I am not sure. Steemit.Inc seems to be putting the resources on Steem rather than the platform which reinforces my view.
