VIX futures exploded during those days, causing a 5 years in the making short squeeze. When they were done rebalancing that night, this shit lost almost all of its value. And according to their prospectus, with that kind of drop they had the rights to shut down the instrument all together.

Like the first line of the prospectus was 'The expected long term value of this ETN is $0'  
  
 It was never meant to be held long term. It wasnt even meant to be held over night. Only traded as an intra day hedge.  
  
 Morons held a ticking time bomb and were suprised when it eventually exploded and blew their dicks off
