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
ICO will eventually run out of control because there is no regulatory board to check if the roadmap is attainable and the testnet and mainnet are really going to work, everyone is for himself, and there are a lot of connivance going on from ICO rating, some bounty managers and influencers.
Every one of us here has become a victim one way or another and if we are not going to be very careful we'll going to be a victim again.
investors still want to invest and always on the look for a good project, and IEO has become their new ground.
