STEEM isn't a concept unlike many other hyped cryptos still under development or those that are active but do not have a real usecase as of yet due to poor adoption. STEEM is being used right here and a very strong community behind it is a positive sign for sure. It is undervalued, tremendously so if you compare it to the competing cryptos. It might take some time but a $1B market cap may be around the corner soon enough. Let's cross our fingers here.
