Meanwhile, there has been plenty of speculation that bitcoin’s big rise may have been due to a pump-and-dump scheme. One theory that the U.S. Justice Department is reportedly looking into is that the digital coin Tether (which is supposedly pegged to the U.S. dollar to make for a less volatile cryptocurrency) was used to manipulate the bitcoin market and cause a large run-up in price.
