It definitely will. 4k is a very low estimate - just my opinion ofc, based on it's use cases, projects & history since 2017 I would think something like 8-10k is very possible. 4k, absolutely. This of course is only my estimate on it. Everyone should do their own research.
Currently the price of ETH is $3600 and will be very close to the price of $4K, so the chances are clear that it will happen, because ETH is a very popular coin from the past until now so to reach more than $4K it would be very possible to happen
