Steem has a vibrant future because I beleive more media house will surely wants to turn into a decentralized hub where there will want to rewards also their users and audience alike. And all these will make them come into the steem blockchain through there own SMT which will helps in spreading the awareness of the steem blockchain and it's scalability features to the world. Steem is surely going to become the global hub for social media platforms where the users will be rewarded for their time and content they produce
