IEO are the bad face of Exchanges. I don't find them interesting. It's not that just filing a google spreadsheet with some data that makes a coin more reliable. With IEO Eschanges pump and dump as they earn more fees.
When you are not speculators and you will definitely say if that was a bad thing but for those have earned more than 10x return for their investment and they will say the opposite thing. IEO gives more guarantees than ico and that looks better even exchange site was taking a little fee but that's not a big deal.
As long as the platform can be trusted and i have no problem with it.
