I guess the typical reply is that we mostly know about the stupid ones who get caught. But it would depend on the crime types, I guess. With some crimes, if the person is really meticulous and clever, chances are also they probably managed to make their business legitimate, like they just become a politician, and get their gains from lobbying and writing "books" instead of running cryptocoin scams.
