This is very interesting. It seems this is the first project that I know holding an IEO together with an ICO. Quite an interesting move by their team. I hope this is a perfect move for them to gather funds needed for their platform.
I believe this is an attempt to give greater credibility and strong to the project. One of the biggest difficulties in some ICOs is the submission of tokens to some exchange after ICO is completed.
I agree that listing or getting listed in exchange is really difficult especially for start-ups and Pointpay was able to do it. Vindax had confidence with the project that is why they were listed there.
