The only thing I see about ethereum is that it enjoys being the first alternative to Bitcoin and being the first to house a lots of external projects on its blockchain.
Another about the reason for ethereum being performing in price more than other alternatives which are obviously (to the pros) better in term of development is because most of the new crypto investor do not know about the technology and technical aspects of what they invest into. So, they rather go for the big name in the Cryptocurrency world which ethereum conveniently belongs to.
Exactly. The only thing keeping ETH as the biggest crypto after Bitcoin is the first-mover advantage. If it wasn't by that, ETH would've been "eaten" by its competitors already. I guess it's not about what new features a coin has, but rather how secure and reliable a coin is. Compared to other smart contract platforms, ETH is the most widely-developed and trusted cryptocurrency on the planet after Bitcoin. I guess that's more than enough for ETH to retain its place as the "King of altcoins" for a long time.
While I don't like the ever-rising gas fees of the ETH blockchain, no other competitor outmatches its level of decentralization and censorship-resistance (although it can be debated with the recent switch to PoS). People will ultimately decide which coin stays at the top, and which coin goes all the way down the drain. At least, the competition is healthy. As long as there are a wide variety of options to choose from, nothing else matters. Just my opinion
