I believe Steem dollars and Steem will move hand in hand because if Steem dollars do go to $100, it will make posting on Steemit worth a small fortune. As Steem dollars go up, Steemit user growth would rapidly accelerate. I think this is kinda why Steem is a wild card in 2018. If Steem dollars were worth $100, Steemit would have over 10 million users by years end.
