I believe it is still early adoption phase. That being said I also believe that a mass adoption or explosion of interest is going to be very slow coming or even unlikely. I say this not because I don't believe in the platform but because of the already established competition and the crypto stigma. Most people I know will never hear about Steemit because they are not involved in the circles of people who promote it. I only heard about it a week ago. Plus, from what I gather from people around me, crypto currencies are regarded as a waste of time or at worst even a scam. I believe Steemit does have a chance to go big, it's just not going to happen anytime soon.
Just my thoughts coming from someone new to the steem and crypto world. Apologize for book and bad grammer.
