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.
Are you saying that IEO replace ICO? actually, IEO was not differ to ICO, they are both no guarantee to say that the token has a potential or not?
Just all I can say is that in every form of investment in the project has a risk involved, now since IEO was too trending so far it doesn't mean ico is not useful anymore, of course not! they are both still give opportunity to anyone here in the crypto world.
In general, ICO is useful means of crowd funding no absolute doubt about it, but right now, its image is seriously getting tarnished, and investors are not even helping matters any longer as most of them now focus on IEO which is shy we see some of these projects too that are not meeting up in ICO turn up to IEO.
He only little luck hunters have now, is that they still conduct ICO, raise the little they can raise, and then go to IEO to conclude it which is good for hunters because it shows that they will be able to get their money when it enters exchange. Still trying to see how ICO can still be fully revived again.
