This is a continues question until the ETH reached the said amount(though i doubt it will happen in the next 2 years more)
500$ maybe possible if the price of Bitcoin starts to rally again to at least 15k$ .
You are right. $ 500 looks more reasonable. don't expect too much. buy now and hope a pretty good increase. no need to be greedy with too high hopes. It is not impossible, but tips must look at market conditions with the current reality.
$400 to $500 is the minimum price that ETH needs to achieve this year because if the market continues not to have much big improvement then people will not be interested in investing in these coins. The price of ETH will depend entirely on the price of Bitcoin so for ETH to reach $500, Bitcoin needs to reach $14,000 soon. Of course, this is just my prediction because people care more about profits than project quality.
