in 2017, it was not even close to actually reach $3k and by saying in 2020 we will touch tha price range is actually really hard because that means Bitcoin must be in $50k range or even more to actually make it true, without adding legitimate proof your speculation is not going anywhere and doesnt have any value on it without proper speculation
We can't be sure even if bitcoin goes $50,000 the price of Ethereum will be unknown but that time. But the usual pattern leads like that, if bitcoin's price is up, Ethereum is a must to follow the price increase of bitcoin too.
There are a lot of speculations of bitcoin going to $50,000 so for Ethereum to reach $10,000 or so, there's a possibility it will. The condition made by op is by this year, maximizing the volatility of Bitcoin and Ethereum, it can't just happen within this year.
