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.
we should not assume one coin as a dying coin due to success of another one as every coin elevated in price according to their supply and demand. Solana is successful these days and we are agree with such statement but ethereum is also a successful coin which cannot be neglected.
Ethereum is more successful coin and no other altcoin can ever go higher enough to replace the success of Ethereum therefore it is upto a person that in which coin he wants to invest both are successful but Ethereum is not dying and will never happen.
