The question is, did they? I have seen that Carlos guy trolling around with youtube videos and in social media, so apparently he isn't in jail at all.

There's also many youtubers that made a killing promoting this ponzi scheme with affiliate links, with millions of views on their channels, and they still have their channels up and going.

So unless they are waiting for court, nothing happened. The victims will most likely never see their coins again, however they leased the most valuable lesson: trust only Bitcoin.
