Ethereum is not an investment. It is also not a currency or money. Ether is fuel for smart contracts which means it has to have an unlimited supply. It needs to be constantly created so that people can use it to create shittokens (aka ethereum smart contracts).
I've never liked Ethereum for many reasons. First, it's an altcoin with a network packed up with many lowquality tokens that have no future potential. This leads to extremely high fees for even small transactions. I question its value as an investment. While some people may invest in Ethereum, I believe it's fundamentally different from Bitcoin and shouldn't be compared to it. Bitcoin has a limited supply, making it more valuable.
A key characteristic of a good money is scarcity, which increases its value. Ethereum, on the other hand, has an unlimited supply, reducing its potential value. it can't be a reliable store of value. People who hold Ethereum and other altcoins often do so for transaction fees, especially in the web3 space not as a long-term investment.
