ethereum is the king of altcoins, but they will follow ethereum when ETH rises, and vice versa.
It's best not to forget to look at other projects that are also under the Ethereum ecosystem, then you can look at projects on the Cosmos network that are slowly becoming popular like Celestia, I think there will be many projects that want to join Celestia Modular.
ETH might be king of alts, but it still has this fee problem that they couldn't figure out. When it moved to PoS there was a belief that it would be solved, and fee would be lower, and yet it hasn't been fixed. I think that slows down the increase a bit, I think it has to do a lot better. I know that it is going to take a while, but it has to be fixed in order to make ETH go up as much as it really deserves.
Plenty of people do not use ETH just for that reason, if people used it more, then there would be a lot more ETH being bought, to be used later on. This is why, if we want to see ETH peak on it is ceiling, then we need to figure out a way to make sure that it is doing fine with fees, make it cheap and quite fast so people would prefer it.
