Never say never. Ethereum has not pleased us much in the past, in 2019 I believe that Ethereum will cross the border of $ 200. What we believe in, we end up with.
LOL, $200 per ETH, it will blow my mind away.
Personally, Ethereum is hard to reach such a high price.
Of course, there are probability for it, but it is very low.
Bitcoin, itself, has to struggle to surpass $4.2k, hence it will have specific effects on altcoins, and ETH definitely will be affected.
