Maybe PPT ICO official ending in Aug 15, but all tokens have been sold during the Pre ICO, probably that site has obsolete information. I see the only way now to gain PPT for 4$ per token or wait for unlikely price dump.
it ended over a month ago. this is because tokens have sold out in the pre sale so there has no longer been an ico..
and everyone just went crazy because the price has gone x10 of the ico price..
