It was already proven that he is indeed not satoshi nakamoto so he has a lot of explaining to do. He will be in even worse trouble if the money he has accumulated came from illegal activities. I wouldn’t want to be in his shoes right now.
The money probably didn't came from an illegal activities but nonetheless they're probably dirty, I mean he's got a lot of supporters that believes he's Satoshi Nakamoto so it's not impossible to infer that he's got some kind of financial support from those people. I don't think that CSW will ever consider telling that he's not really Satoshi Nakamoto, he'll probably going to commit to that joke until he's on his grave, the delusion that he's got is just too strong to admit defeat in the face of an unrelenting adversity which is jail time, dude probably regretting it inside but has to commit all the way.
