A man accused of operating a bitcoin exchange allegedly owned by the mastermind of a criminal enterprise that hacked at least nine big financial institutions and publishing firms, including JPMorgan Chase, pleaded not guilty to money laundering.

Anthony Murgio was charged separately from three alleged hackers who are accused of stealing information on more than 100 million customers of banks and publishing firms and generating hundreds of millions of dollars in illicit proceeds from pump- and-dump schemes and online gambling. Murgio wasn’t accused of participating in the hacking scheme.

Coin.mx, run by Murgio, was used to launder the proceeds from the crimes of the global network, which stretched from Israel to the U.S., according to prosecutors.

During an appearance in Manhattan federal court Tuesday, Murgio also pleaded not guilty to running an illegal bitcoin exchange, wire fraud and conspiracy.

U.S. District Judge Alison Nathan scheduled Murgio’s trial for Oct. 31. Murgio, who remains free on bond, declined to comment after the court appearance.
