3) the operator of sheep market was an amateur. He has been doxed. Probably he will end up behind bars soon, and in any case he will have a hard time cashing out the coins. Look at how he is desperately trying to launder them: it's pathetic and amateurish, you just cannot launder 100k coins as he is trying to do because there aren't another 100k from other users to mix you coins with. Either he cashes out in small chunks from localbitcoins, either he is caught very soon.
What if he boldly sell them on an exchange? Who's gonna stop it? Who will sue him?
And why should he be in any hurry to dump?
Nobody will sue them, LE will arrest him with similar charges as per DPR. They already have its full dox.
If he boldly sell the coins on an exchange he will get caught immediately after.. All kinds of AML/KYC procedures are triggered at both the exchange and bank level when somebody tryies to cash out dozens of millions quickly. Bitcoin liquidity is still a joke.
Secondly, just look at the guys Facebook and at the amateurish mistakes he made leading to his dox. Look at how ridiculously badly coded was the SMP. And finally, amuse yourself watching how the guy is desperately trying to tumble the coins, failing hard because he is anxiously trying to tumble all of them instead of leaving the big stash in a few addresses and tumbling just a few hundreds every day (the only way to effectively launder such an amount). He is mixing his own coins over and over, that is very telling - he is an amateur and he is anxious.
If I knew I would get caught anyway I would dump them just to see the world burn.
