"The analysis showed that "substantially all of the volume" reported on
   71 out of the 81 exchanges was wash trading, a term that describes a
   person simultaneously selling and buying the same stock, or bitcoin in
   this case, to create the appearance of activity in the market. In other
   words, it's not real.
   Those exchanges report an aggregated $6 billion in average daily
   bitcoin volume. The study finds that only $273 million of that is
   legitimate."
