ETH has become the ICO coin, and unfortunately this has also brought a bad side, and now we have tokens popping around everywhere and ICOs are dying ...
The thing though is, I think the ICO functionality of ETH is actually decent. It's just that people are taking advantage of the hype and make scammy ICOs solely to make money. Because of that, are we really going to blame the Ethereum platform for that? It's mostly the people, the gullible "investors" faults that these scammy ICOs earned money in the first place.
BNB is the Binance coin which is now a days more popular in the crypto industry but it is quite difficult to say that it is the Ethereum of 2017 because Ethereum has its own movement and showoffs. Unlike Ethereum the Binance coin is popular now days and many people are investing in it. Ethereum is also showing resistance and follows the uptrend but it will take time to gain its 2017 conditions.
