The idea of the project itself is interesting but I was confused by a few moments ... First, the project was not anywhere in the rating tables (or I missed). Secondly, why should they go to IPO if they already collect the right amount now (on ICO)?
I found ratings for this project on IcoBench. It has pretty good ratings, go ahead and check it out.
