Steem's platform is interesting but i'm not sure if a lot of people are convinced with its significance. Despite it's uncertainties, i still believe its developers are still on to something. The coin has potential and as long as it will attract more investors and the technology proven to be useful, there is a chance its value will rise. Although, there is no assurance for such for we will never know what will happen next but risk will always be in play when we are investing.
Platforms based on social networks are always interesting,but require continuous development,without it people can choose to migrate to other platforms.
