Solana is doing well but it is foolish to assume that Ethereum is dying. Ethereum is far bigger than Solana and its ecosystem is bigger than Ethereum itself. It is because of its ecosystem that Ethereum will not die. The reason why Solana is not trending in the crypto world is due to the meme coins that are in its ecosystem and the way it is going it might get known only for meme coins.
Op is even confused of himself. Ethereum now is rating/rising to $4k and while Solana is still $180 and Op is saying that Ethereum is dying well I don't know which kind of dead he is referring to. In this cryptocurrency market business or investment everyone has their own coins or projects they like most. Some of them like altcoins because they could not bought bitcoin when it was cheaper and they think they are late in the investment today because of the price, so they just join the lower projects which they can buy with small amount and hodle it foe either short term or long term investment.
Solana and Ethereum are all good to invest but you don't have to compare Ethereum to Solana even though all the two networks are congested Ethereum is still superior to Solana.
