If we see thw growth of BNB now it is will making ETH move.
But ETH is keep strong and still good coin for now, maybe if BNB can overtake ETH it need a long time like 5 year or more.
Juat my speculation for this case.
it is because BNB is more growing in this year and makes people think If BNB will overtakes ETH, I think ETH is stronger than BNB and this is not a fight but this is who the best coins is are. everyone already knows that ETH is a good platform and a good coin, it takes a long time to be popular on crypto like Ethereum. of course BNB must try hard to be popular like Ethereum.
Looking at the time when both were born and built up a reputation in the market, ethereum probably still dominates when it has so many good achievements, has a long-term connection with this marketell in that job but everyone should consider clearly, this is the crypto world, the explosion and the creation of magical stories can still happen. BNB has qualified and opportunities to create that feat when it is still pushing very hard and every day with bnb, it is a different development step while ethereum is starting to become as slow as a turtle
