Another tought i have:
 
I was thinking that auction held, lets say 1. day of every month, with 5 stakes at a time for a year could keep the price a lot higher and be better PR, than auctioning 'em all at once. Weather it's in NXT-AE or not. And give the rest either for stakeholders or to charity on NEM's first birthday or something. Stakeholders could vote what is the best charity.
