Those who think that bnb can take over ethereum and become the number 2 crypto currency after bitcoin lives in fool paradise. There is no way that bnb can surpass the ethereum marketcap. The Ethereum network is far more superior than binance smart chain and it is not possible for bnb to replace the ethereum position.
Only time will tell, since we are only talking about marketcap here its close to possible. Binance chain is gaining huge popularity now, some projects already migrated from Ethereum to BSC and new projects are attracted to it. In short period of time it might shock us all, who knows?.
