The price of ETH will be approximately $300 in 2020. My prediction is positive but the next market conditions will show how strong feelings I have. The ETH deserves to be $2000 coin, in my humble opinion.
It all depends on when the ETH fork happens, if it happens in 2020, then of course the ETH price should rise very much, if not, then the ETH price is unlikely to rise much in 2020.
