We cannot expect a price rise like 2017 for Ethereum again. It can go up a few times to somewhere between $500 - $1000 by end of 2020.
The highest increase in ethereum was in early January 2018 and after that it has continued to decline until now. and I do not believe that at the end of this year it will break $ 200 because the influence of bitcoin is quite pronounced. but if in 2020 there are many possibilities. it could be when the peak of the highest price of ethereum actually occurred in 2020, that's the desire of many people of course. we see in early 2020 how will the movement lead to positivity.
