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.
I agree with you, one has to be careful about investing in projects. I know some new exchanges have been set up to steal from investors as they support IEO on their sites. I'll advise that investment should be done with only the amount one is willing to loose.
