I know that there has been hype all over the forum on IEO projects and we trust them because they are being guaranteed by exchanges, most especially top exchanges. Now the question is, what does exchanges do differently that makes them certify that a project is not a scam project and have a reliable team or that the project will stand the test of time?
IEO listed in exchange platform is actually a guarantee, that the token will be listed and traded in that exchange after the sales completed.
Also we can avoid non legit ICO that can turn into a scam ICO after they got revealed by others.
So, it is better to buying some IEO token because you can trading it later with a good volume in the exchange.
