The phasing out of ICOs has already begun. We have already entered a new evolution phase of the IEOs which most previous ICOs have now also turned to.
FYI, IEO is an ico but that already cooperated with exchange site after there are some negotiations. The fact that it will be difficult to search IEO that already created a fully working product like what already done by HNC which already accepted by so many merchants in greek.
When you create ico and then a few times later you got called by exchange site to create cooperation with it and then you got your IEO.
Something is more relevant than it just like a coin which already accepted by merchants to create such a real usage.
