I don't agree. Ethereum is way above Binance. Binance for now may be at the top but only insofar as their exchange is concerned. And mind you, the exchange ranking is very fluctuating. But in terms of blockchain and their platforms, Binance cannot simply equal Ethereum. The thing here is that Binance is a bit noisy everywhere, hype, media attention, and the like. But it only takes a quick browse over the internet and be amazed by which companies use the Ethereum platform. Ethereum is a legend, my friend.
In the end BNB will end up like IOTA, which has lost 90% of its value (against BTC) since the beginning of 2018. Ethereum is of a different league altogether. It was first listed almost four years back and during this time the developers have worked hard to eliminate the bugs and deficiencies. It has emerged as the most popular platform for launching tokens and smart contracts, with more than 90% market share. Now this can't be compared to BNB whose only function is within the Binance exchange.
