Well Ethereum never died, it is only moving in consonance with other altcoin but trust me, ethereum might surprise us, also it has more acceptability after bitcoin so we hope to see the value of ethereum rise.
Ethereum does not particularly try to develop in the market, now there are coins that are much superior to this coin , I think in the future this coin can go down , as many altcoins go down in capitalization, because very strong coins enter the market.
