Invest only in good projects not because they are IEO projects ,find out what the project is all about before investing ,make sure you know what the project is trying to fix ,the reason why many projects fail either ICO or IEO is because we have too many repetitive projects already ,we need to be careful
That is the best way to go about it mate, at least we always get the chance and time to investigate an IEO project first before the opening time, exchanges always announce their intention to launch a project on their platform weeks before the launch date.
This indirectly means that exchanges wants us to also get the chance to do our own research of the projects too before deciding on if to participate or not. We should not invest in an IEO project just because it is coming from IEO, but because we had made our own research too same way these exchanges do before registering them.
