My understanding for IEOs is basically instead of project handling raising funds etc. It will be for an exchange to do so.
An IEO hosted by Yobit or Binance can clearly not be compared. In other words, the exchange gives more credibility to the project regardless of whether it's worth it or not.
Am I the only one who thinks this is actually a bad thing and make people focus on the exchange hosting rather than the actual project and what the team is offering etc.?
Now for the quality of the project, or rather, the future cost of the token is indirectly the responsibility of the exchange where IEO is held. I think that you are right, the exchange directly affects the interest to the project.
