In my opinion, it is not possible in the near future but BNB is the best coin and good candidate to investment there is no compare between BNB & ETH because of different platform.
Indeed, they are different platform but we are talking of the market spot here.
ETH is currently at no 2 now in the ranking, so BNB has to beat its ranking and will have to replace ETH for that, to see that happening, BNB has to increase 10 times from its current price now, which will only bring it to 370 usd, I see it's possible since BNB already have 6 times increase this year alone.
Ethereum is more than a coin of the popular exchange and BNB will never surpass ether for this reason.
