If I am not mistaken, by the end of 2018 the ICO project has been abandoned by many parties for various reasons that have emerged and turned to the IEO.
If the project is good and trust worthy, then it does not matter whether IEO or ICO. It will be successful.
I really strongly agree that ICO is not completely abandoned. And not everyone also invests in the IEO. As the
ganeshramk said, it all depends on the project. If it's good and very potential for people to invest, of course people won't see the IEO or ICO.
