I think IEO is much better than ICO. In IEO, exchanges check projects and this is the safety of investors who invest in IEO. Also, the token is almost immediately traded on the crypto exchange where IEO is held. How much IEO will be popular is hard for me to tell, only with time, it will be clear. When investing in IEO, you also need to check everything and pay attention to the project when investing. Good luck to all.
It's quite better than ICO from the feature that makes the IEO can be listed instantly on the exchange site. But again, how good the IEO depends on the exchange site and if that was launched by crap exchange site and i believe if the future of token will be the same and that will dead instantly.
IEO projects like that will be difficult to get the trust of investors, because they realize that the crypto world is very risky, of course they will choose projects with a good exchange basis. on the other hand, they don't want the scamer to develop, so this is one way to do it
