All I can say is maybe, it has a posibility to replace eth both bnb and eth is good coin and thier rank is very closed eth is #2 and BNB is rank #3 so a great posibility that bnb will soon replace eth is there, but maybe not this year I think it always takes time because eth is also has a great foundation it is also an amazing altcoin that is very well known to investor's.
my opinion is different, I am not sure bnb will be able to shift ethereum...
bnb predictions shifting ethereum is the same as ethereum shifting bitcoin it's totally impossible. Until now, Ethereum transactions are still very high, and that proves that ethereum has not been abandoned despite its large gas fee.
