I think This is a natural part of any new market/tech, i do believe bitcoin still has a Big prt to play the next Two or three years, and eventually hit upwards of 50,000$, but the same time that happens I think there will be a diversification, app coins are for sure going to be the next big one. Unfortunately I don't think Steem will be the winner, I think Steem before next summer will reach about 10$ but then I think January 2020 will bring a new social media platform more mature to the crypto space and more aimed at the masses that will take the throne.
But hey that's just my two cents
