Because there is no ICO anymore, the current trend of crowd sale now is the IEO.
Let's just say that In 2017 and below, it's the year for the ICO but 2018 onward are the year for IEO and BNB would prove that because Binance is one of the popular exchange in the market and BNB had its all time high this year.
Of course, we can see the ambition of Chinese exchanges, especially Binance, as they seem to be looking to compete for ETH's position and role. OKB, BNB, HT all grew very well and were much closer to its ATH price than ETH. So we can catch this trend to take the advantage.
