Considering the current market conditions, "ETH can reach $ 2500 levels?", BNB's own network makes strong rivals such as TRX and EOS to make Ethereum's job quite difficult.
I think BNB will be big opponent for ETH. Because BNB gradually going to stronger, non stopped pumping/dominate whatever you considered. Although in 2018 it total market cap was around 1 billion but still now within some days BNB will reach big milestone 5 billion market cap.
