Usually it's a bad sign when such special plan appears. It means that a hyip admin is going to grab more money before escape soon . So, be careful, don't invest in this program for the moment.
More than, there is another bad sign, my withdrawal is pending more than 24 hours instead of 12 hours maximum for payment processing as stated on the site.
