Steem is one the few crypto-currencies that has a developed and fully functional platform behind it. 

It has a real world use case which is very uncommon in the cryto-world. Even a layman can see the use case for steem. In my opinion Steem does have a bright future ahead unless and until they dont mess it up themselves like Yahoo or Orkut. We all know that at one time Yahoo was way ahead of Google but just look at it now.

The technological niche is a fast changing sphere and thus to survive in it one has to be constantly addressing the shortcomings of a platform. As long as Steem is performing better than its rivals it will have a Bright Future.
