As you know Binance is growing fast exchange and BNB is also increasing day by day, i think in future may be BNB will defeat to the Ethereum,this can be possible .
binance did experience very good growth, but the development was not as good as the development of ethereum, all possibilities could have happened but for that, it took a long time.
we are indeed talking about the future so that it does not rule out if the BNB has the potential to develop far better than now and will even surpass Ethereum but all also depends on Ethereum because if Ethereum also develops well then Ethereum will be stronger in the peak.
