If ICO wasnt been plague by scammers acts ICO will way better than IEO, ICOs are programmed to run on the projects very own website and no any third party involvement at all so any fund raised will go directly to the dev or project team, no loss of funds to scam exchanges,after some successful IEO fund raise on some exchanges they dont bother to send the funds back to the project teams
We are wiser now than before, but still some scam projects can get in, I will still not invest in ICO because there is still no regulation here and it will take some time before you can trace if the project is legit or not, not all of us are good in tracing good projects, we still rely on reliable people in the community to give us pointers and reviews of projects.
