Is there any articles that clarify what these guys were actually doing to make the money? The fact that they don't mention it makes it sound like they might have been doing something more interesting than just selling drugs, as usually they tend to be fairly public about those cases. Edit: Guess it was just some drug dealers then, >All suspects fell into one of two categories – criminal “traders” on the Dark Web and “bitcoin-cashers” who are paid by these traders to exchange bitcoins for cash
