You are right, Solana is a baby that was only born 4 years ago, it still needs a lot of time to become as popular as ethereum which was born 11 years ago. Solana is a tough competitor for ethereum in the future. and Solana is predicted to replace ethereum in the future.
BSC? You are right that many people say it is less interesting because of centralization reasons
SOL is good, but there is still a lot of improvement to be done, and it is only natural that in the short time it has been able to reach this point. This is certainly something that other competitors need to pay attention to.
But will it be a replacement for ethereum? There will always be opportunities open, but can he achieve them? Of course time will tell that.
I myself think there are still BSC that are still very good and have been proven to be able to contribute to their users. But in fact, for me, it will be better for competition, so for users there are other alternatives.
