Ethereum is the second largest cryptocurrency after Bitcoin. No other ultracoin compares to Ethereum. I have always considered ETH to be the king of Altcoins and I believe ETH is the most successful smart contract platform that other altcoins have yet to create such a successful platform. And anyone who prefers Ethereum to invest in Altcoins has the biggest fan base.Ethereum is very popular and I think if the gass fee can be reduced then its investment will increase.I always invest in Ethereum and hold some my wallet.
With upcoming network upgrades aimed to improve the Blockchain's transaction capacity, one would expect ETH's position to solidify in the market. The vast majority of alternative smart contract platforms use the Ethereum Virtual Machine (EVM), even though many of them claim to be the next "Ethereum Killer". It's like saying Edge will "kill" Chrome even when it's based on the same engine. Ethereum essentially became the dominant smart contract platform because of its innovations. Not to mention, it was the first Blockchain to offer the ability to write and/or execute smart contracts.
ETH has first mover advantage just like BTC, so it's practically impossible to take it down as the world's second-largest cryptocurrency by market cap. Who knows if many altcoins will die, leaving us with ETH and a few oldies (LTC, DOGE) "to play with"? Just my opinion
