As for ethereum, I have no hope on that coin more than I use to in the past. Ethereum is almost becoming more of a shitcoin than just an altcoin following its price performance where bitcoin is.
Not only is ETH underperforming in this cycle, but so are most altcoins, while Bitcoin is constantly growing and breaking ATH, most altcoins are falling. This is not because they have become weak or stopped developing, but simply because of the changing market cycles. With bitcoin ETFs being approved, we have a huge amount of money pouring into the market but ironically, most of that money is concentrated in bitcoin, making speculating on altcoins less attractive.
But if the 4-year cycle repeats, the bull cycle is not over yet and there is still room for ETH and altcoins. I don't know what's going on and can't guarantee but we can see after a series of gloomy days, ETH is showing signs of significant recovery with an increase of almost x2 since the end of April until now. Its performance has been better than bitcoin in recent days and that could be a sign of a comeback for it and altcoins.
