The thiefs are cashing in from there robbery i see 
Mark Karpeles stole BTC850,000 and he is still living freely and happily.
The Sheep Marketplace thief is nowhere to be found after stealing some BTC200,000 coins. And now FBI stealing another BTC180,000. Bitcoin is the favorite currency for thieves. If I were him, I should be looking for a good lawyer now that Ulbricht's case is done.
Todays price roughly $200 million i am sure he has a fairly good lawyer,
Plus nothing will happen to him imo it would have already he was probably part of some government btc robbery team like the FBI
Well that is just a theory and i have no proof of course.
