If I am not mistaken, by the end of 2018 the ICO project has been abandoned by many parties for various reasons that have emerged and turned to the IEO.
IEO just another words from ICO, or maybe we can say if IEO just an evolutions from ICO my friend
same purpose, but different way,,
and a lot of people said if IEO is better than ICO, because the project will automatically tradeable on the exchange after the IEO finish and reach the cap
