It's a pretty old cryptocoin: initally released back in 2015, and a significant change deployed in 2022. It was then when they changed from proof-of-work to proof-of-stake, which basically means that they don't use mining anymore to keep the network running. They use like 1% of energy compared to PoW coins.
Also they have some smart contract capabilities which I suppose Ethereum people think are important. But I've never seen any practical use for that stuff.
Still, I think Eth is one of the cryptos that actually tries to be useful and efficient in some way and not just a stupid pump and dump scheme. Turns out, nobody gives a fuck about that, perhaps?
oh whoops
