The truth is ; steem may be the future big thing! , but not the next big thing! Lots of people will turn to the next best/big thing and lets be realistic here, there are lots of options out there besides steem for people already aware and involved in cryptocurrencies.
For now, steem is mainly important to the steemit platform and it isn't necessarily a bad thing. The potential growth of the platform is huge, and so is it's cryptocurrency , steem. As I continue to point out, the advantage of steemit is that it connects a growing social community to the cryptocurrency market. Millions of people will be introduced to steem before they even know anything about bitcoins.
You can refer to steem as a Sleeping Giant☄
