i don't think BNB can replace Ethereum position even they are backed by Binance exchanger.
Ethereum community more stronger than Binance, even this exchange one of big exchange in the world, still still have big space in community, and about the price we can value ourselves in the market
There are a lot of rumors going around the crypto exchanges regarding replacing the second top altcoin in the cryptocurrency market. Those arguments are not considerable and constructive because of the increasing trend on the IEOs. The Binance is not only exchange offers the IEOs and I remember the gold years of the Bittrex which is the first big altcoin exchange. I don't want to see BNB as a second altcoin in the market if there is no proper bad news against the Ethereum's scalability.
