I don't think if Binanace BNB can beat Ethereum ETH because it is almost impossible.
I know BNB is really good coin, but to beat ETH is need more than good coin and good exchange.
That mean good blockchain like ETH have ERC-20 and almost all new token used that blockchain and making Ethereum is bigger.
l do agree with your words, to beat ETH is needed more than a good coin and also good exchange. BNB is also a good coin, but l don't think that there can be any altcoins, which can beat ETH. ETH is the second cryptocurrency. ETH is increasing and no doubt it will keep increasing, ETH 2.0 brings good effect to ETH and we will see better ETH than right now.
