In my opinion the ETH price in 2020 will probably be very high. Because at that time i thought Bitcoin could be a worthless currency at all $ 100,000. We can not know before. But Bitcoin can do wonders and magic. ETH will therefore benefit greatly from Bitcoin.
I think it is much higher than the expectation price. 100000$ is not a little amount. People will not be able to maintain the crypto currency. It is almost impossible to reach 100000 with in 2020 for bitcoin.
