IEO basically replaced ICO. So, for me I don't mind if ICO will have a come back. But personally. If it did, I would still prefer IEO projects because I feel safer with it compared to ICO.
IEO offers a better thing than ico. IEO will be listed on the exchange site who have been launching it and ico needs to apply manually to be listed on the exchange site and i know that if you still prefer IEO rather than ICO caused by this thing but we should not underrated the ico too.
