$50 is too conservative in my opinion.
I have a target of $100 by year end.
I think SMTs are really going to create a frenzy. Steem has the ability to be a top 10 blockchain, like you said. With SMTs, I think we can see an ETH type move in 2018 like that did last year.
I think the communities are going to add a lot to the site and the value people receive.
It is exciting...I am anxious to see this stuff rolled out.
