I really believe in the Etherium, it's really ideological. Next year, the team will unload a huge set of updates and news. I believe that in 2018 ETH will cost about $ 1000.
Eth raised 1200$+ in 2017 so your prediction was perfect when you predict. But 2018 is totally against of cryptocurrency.
Whatever is happened in 2018 but i set new prediction in 2019 will strong market also good future ico project.
