The U.S. government tracked down Bitcoin transactions in the Department of Justice’s indictment of Russian election hackers.
The Wall Street Journal’s video notes that there are now a number of cryptocurrency detectives who are (or at least) advertise themselves to be able to track stolen tokens. Kim Nilsson cracked the Mt. Gox robbery.
But the question remains as to whether a victim can ever recover them once they are found residing in the thief’s digital wallet.
