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.
it's not impossible what you predict will happen for the next week because it looks like everything is going up and the market is starting to get excited, so it's only natural. All of course hope that will happen so that altcoins also start to get excited.
Ethereum will go for four thousand dollars, that's normal because it happened before. So, i think it will hit $10000 and make it last ATH. But it can happen in next year like 2022
In fact, the best ATH will occur at the end of this year and the price will be achieved because the last ATH is already half way but has been corrected so that it doesn't need to be until next year but will happen at the end of this year.
