ethereum is honestly not doing that well these days but is doing enough to keep itself second to bitcoin and not let any coin outshine itself still it will take a lot for another coin to emerge ahead of ethereum especially given its history and as for bnb i do not know if a coin associated with a platform but since it is widely used anyway i guess it will be not so much of a problem
ethereum indeed remains in second place CMC even though it has not shown good movement in the crypto market for the past two years.
BNB still shows its potential as a coin from the largest exchange.
And solana in the past two years, has shown good progress because many hype meme coins use this network.
