We are able to reach $600 in just a week, now we're looking forward to hit $1000 this quarter. BNB is indeed on of the best altcoin today, they keep on growing, can't way for the next tweet of CZ Binance about the "not a financial advice" series.
At this point, you can't really compare BNB with ETH. Right now, BNB is mostly known as an exchange token and not many projects are opting for the Binance chain. ERC-20 Blockchain is still preferred by the vast majority of the projects (irrespective of the sky high fees). In the smart contract sector, it will take a long time for BNB to catch up with Ethereum. So these talks about BNB replacing Ethereum sounds a bit premature for me.
Having said that, ETH is like Bitcoin of altcoin market and shouldn't be compare with BNB. Besides, if people survey very well they will know that CZ also integrated the idea created by ETH and once the ETH2.0 last phase is executed the chance BNB had over ETH will be over.
