Shift right now is still going good, its price now is $2.38 and i think this price up will continue. Shift now is becoming more profitable, thanks to all the devopers that work hard to make this thing happen. So in my own opinion by the end of 2017 its value will become greaterthan $4.
IMO the price will not go beyond of $2 by end year,however the project seems quite ambitious,but maybe I should read better first before formulating a more appropriate idea,on the other hand it is interesting that this project shares a developer with Lisk.
