As, the entire cryptocurrency market is in the green mood and the bull run is gaining momentum ethereum price at the moment is already above $3k which is a sign that ethereum will reach $4k before the end of this week that is a week after the ethereum London hard forks. Just my prediction.
if bitcoin hits $ 50k then surely ethereum will be at $ 4k...
the price increase that occurred on ethereum in recent days was influenced by the increase in the price of bitcoin. bitcoin price is slowly but surely heading towards $ 50k, when that happens then ethereum will definitely hit $ 4k.
Bitcoin still has big influenced with how the entire market move along, and like what you said if bitcoin move to that range
and more investors to come inside the market.
Expect that there are more actions that will take place, ETH as the next coin after Bitcoin popularity will benefit with this movement
and yes $4k is very possible now might touch it again before this year ends.
