An official with Liberty Reserve, a popular digital currency service, has pleaded guilty to money laundering and operating an unlicensed money transmitting business. The U.S. Department of Justice shut down Liberty Reserve when it filed charges against the service. The DOJ indicted Liberty Reserve and five other defendants in May 2013 for allegedly laundering US$6 billion in a series of global transactions. The service was created to help users conduct illegal transactions anonymously and launder the proceeds of their crimes, the DOJ said. The $6 billion transactions through the service were connected to credit card fraud, identity theft, investment fraud, computer hacking, child pornography and narcotics trafficking.”]
