the emergence of the IEO has attracted many new investors and old investors, most investors, are now turning to investing in IEO. but remember, we can't fully trust IEO, I'm very sure that something good can turn bad at any time!
the world of cryptoqurency is very anonymous and you must always be vigilant with every action you will take.
In general, we really can't trust anything here because of how anonymous people are but you can't deny that IEO is a good upgrade to ICO depending on the platform. Most of the IEO have succeeded and already have exchange to trade with which is important for a project so start with. I think the one thing that people should be careful from is the exchange that a project is in. The higher the reputation, the best result you could get.
