Right now with BTC bear trend, everything is hard to predict what will be the ETH price. Hope 2019 will bring good raise for ethereum and all alt in general.
I think that the real growth of the cryptocurrency market and ETH will begin in 2020. We are waiting for not very easy times in the near future, but we must show resilience.
You are exactly right, in 2020 it is the end of the dry season because after that there will be further halving from bitcoin, I think all coins will follow the price of bitcoin in 2020 including ETH.
