I think they have been going after most of the scams in the crypto market right now, but obviously, Pig butchering is on the biggest and American is the target for this criminals from all over the world.
And we all know how American government thinks, if they are the victims, there are going to pursue it at all cost. But not sure how they can stop this criminal syndicates though. Gonna be tough and it will take not just cooperation from several agencies in the US, it should be government around the world that should join forces here.
