It won't happen for Ethereum price to jump to $5K in the next few days. The highest price of Ethereum after the London hard fork in my perspective is $4K and it won't happen in a matter of days but within this year.
It will happen but it need one hype news that make people buy it. Maybe 5k sounds too high in this current market condition, it could be there if BTC is going over 50k. But ETH climb to the high slowly but sure, just look at the chart last one week we could see ETH price is slowly going high and there will be one moment the price will jump a bit like 10% in near future
