Right now it all depends on binance and you can't just put like a new coin offering out every week, at best you can do maybe one a month or twice a month and even that is too much which binance can't hold too long if the volumes are horrible. Whereas ethereum could allow you to go to any exchange you want right away, isn't there ethereum ICO that has been on binance before? There has been son IEO is not the only way and I doubt it will surpass ICO and eth anytime soon.
Ethereum on the other hand can entertain scammers and all source of bad guys to use its chain which they don’t care much about whoever it affects, that is the only reason why I believe Binance will not beat ETH hands down, but if they bend their rule, it won’t take them more than 6 month to remove ETH from its position.
