One important things must all people know of IEO is safety , I think 100% safety if ICO sale launched on exchanges right now , because all IEO has verified team and on era now , so much ICO out there which we mut do research about their team or something like that..
Also , benefits after IEO is that coin listed & ready to trade after IEO end.
Thats my opinion , and i'm very like of IEO system
