I think the price of ETH and BTC in 2019 will increase at the end of the year. Whereas for the beginning of the year BTC and ETH were getting drops. ETH after hardfork will decline to a price of $ 80 or $ 90. Because all ethereum holders will sell simultaneously.
the price can rise drastically before , during , and after the hardfork events . can you remeber what happened on 2017 ? btc did a fork on bch but the price didnt dump instead it result for both coins to reach their new ath's . i think the same thing could also happen on eth and btc this year . btc might not be undergoing into a new fork but it said that sec's etf will have a decision to be made soon .
