Meh, I guess once again it proves criminals are lazy even in the amount of millions it's just time and effort to make it anonymous instead of going through a centralized mixer or exchange.
As for being seized or shut down or anything else. Makes you wonder how long it would take. CM ran for years, so it might take that long. Or it could be weeks / days.
But, not something I would worry about either way. If it happens, then others will pop up to take their place.
