ICO's have now paved way for IEO's to walk through since most ICO's ended as scam projects and never lived to fulfill their promises but the fact that ICO's paved way for IEO's and also many ended as scam does not mean all ICO's are scam projects, some are real legit projects that needs time and funds to rise up and move towards their goals or according to their roadmap so never be quick to judge any ICO because it can really surprise with just some push.
