I don't know, Vanig have been running the token sale for too long to suddenly pause it. Unfortunately, I don't think ICO's are as popular anymore, especially after the recent performances of other ICO's. Maybe they should try another approach and aim for more private sales, but also continue development at the same time. They have nearly $2m to play with this should be enough to get a lot of the work done.
yeah, going the private route entirely might be the better option, ICO certainly have taken a hit, most list below buy in price so it's literally pointless to invest in one during their sale..
