Yes, I think it's because ethereum has fixed some of its weaknesses. And it also needs to be recognized that, even though Ethereum's transaction fees are high, there are also lots of enthusiasts for Ethereum so that Ethereum prices are soaring as they are today. Ethereum is the best altcoin I have ever seen
Ethereum has always proven itself to be great and very useful for everyone in the crypto space so it is still very feasible that Ethereum is under Bitcoin to lead other Altcoins in the crypto space, so I would not be surprised if Ethereum continues to grow very well at the moment.
Of course what you are conveying is very true, since a long time ago ethereum has proven itself to be a great altcoin and it is only natural to be an altcoin that has many investors so that its great impact today has the highest price and is the king of altcoins.
