I wouldn't say that ETH is a bad investment, but the problem is that this coin is less prone to volatility than other alts. The movement to ATH and the corresponding increased volatility last year were more of an exception and may not necessarily happen again.
It's noteworthy that, against the backdrop of the current panic pumping of Brent oil prices, many point out that if you had bought Brent oil futures 10 days ago, your profit would now be greater than that of those who have been holding ETH for the past 8 years.
That's the point. Those who bought ETH in 2021, still haven't profited 5 years later. That's because ETH has been unable to reach a new ATH and maintain its price over a sustained period of time. Not like Bitcoin where it reaches a new ATH and then it stays "in the range". Even with a prolonged bear market.
The "floor" price for ETH seems to be $2k. It doesn't go any lower than that. I'm still waiting for the day ETH gets past $5k. Not to sound desperate, but a new ATH is long overdue. ETH should been worth at least $8k - $10k by now. Validators/stakers must have good faith to continue supporting ETH, even with a suboptimal price range. We'll see if things improve in the future.
