   Dark Markets are a great idea.  But, the people who run Dark Markets
   need to learn from their mistakes.  Even in 2013, I pointed out that
   Dark Markets should be protected from seizure and prosecution with an
   AP-type system, where a small portion of the 'profits' are retained and
   offerred  to anybody who "predicts" the date of death of anyone who
   attempts to prosecute any Dark Market.  Judges, prosecutors, witnesses,
   even jurors if that should turn out to be necessary.
   And, perhaps, a rather serious reward for any jurors that participate
   in an acquittal or even 'hung jury'.    What if $1 million was
   offerred, to be split between all jurors who vote to acquit, and if
   none of them do, $1 million was offered on the heads of those same
   jurors?
   This news item indicates that $1 billion in bitcoin (today's value)
   was available in 2015.   If a person is now resigned to lose it, he
   should have been willing to lose it in 2015, or even earlier, in order
   to avoid having his Dark Market taken down.
   Unlike my 'traditional' proposed AP system, this kind of system
   wouldn't name specific names, since no names would be immediately
   known:  It would only be known who the targets will be once the
   prosecution begins.
