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
You can't really say that IEOs are safer than the ICOs. The current situation of the IEOs remind me of the situation of ICOs during mid 2017. IEO is still a relatively new concept and there is a false sense of security among many of the cryptocurrency users regarding it. But looking at the overall structure, I can foresee serious issues with IEOs in the near future. I have seen little known exchanges listing 25 IEOs at the same time. When you have that many, the quality will obviously go down.
