Ethereum is flying form last few days. I really can not trace the reason of the bullish trend.
However, what is your thought about the closing price of ETH in 2018?
In my opinion, to guess the ETH price is very difficult, but if I can guess, ETH will be able to close $ 2000 this year.
I am very confident if the price of ETH will touch this year's price range and the value of ETH will continue to increase in each year.
