$50 steem anyone? That's my bet for the end of the year!
I think we'll see ~$50 in May or June but I also think it will drop quickly and get below $15 for almost the entire year after that.
By the end of the year? - ~$30.
2018 will be an incredible year for Steemit, Steem and SBD but I think it will just be some sort of "warmup" for 2019. That's when I believe we'll see the true changes. ~$100 Steem and so on.
