I am still optimistic about the price of Ether. In the past, when the price of Bitcoin increased, the price of Ether also experienced a bullish movement. Various critics are now more optimistic about it.
Geoffrey Kendrick of Standard Chartered predicted that its price would be $7,500 in January, even if it did not materialize, according to his long-term prediction, the price of each Ether is likely to be around $30k, especially by 2030. At the current price, $30k may seem unrealistic, but it is not impossible.
ETH is trading around $2.5k right now, with a market cap of roughly $300B and 120M ETH in circulation. So if it hits $30k each, we're talking nearly $4T in market cap.
Honestly that prediction just isn't realistic, and when it's this far-fetched the odds of it happening are even lower.
Since the price of Ether has not changed much in the past few years, there is a high possibility of a big bullish movement. That is why not only Geoffrey Kendrick but also Tom Lee, Cathie Wood and many others are expecting a lot from it.
Plenty of altcoins have been trading sideways for years too . Do you think they're all about to pump hard?

Just because a coin has been trading sideways for years doesn't mean it's about to break out. Tbh, that argument doesn't make much sense.
Look at real demand and what's actually driving growth, not how long it's been flat or how many famous name are calling for a leg up .
