ICO is not dead. More precisely there are already many who do not use ICO. Although there are still a few. Investors trust IEO more. Compared to ICO, IEO is far more useful. Moreover, if the IEO conducted on the exchange are already popular. Then, tokens will be sold out in a few minutes.
I agree that ICO is not dead. There are several projects that prefer the ICO path and are able to achieve the target soft cap. Maybe IEO is faster in achieving the target but for new projects that are raising funds, paying exchanger at a high price is a difficult choice for the developer team
