An attorney for Heather Rhiannon Morgan and Ilya Lichtenstein has claimed that they are not a flight risk because Ms Morgan has frozen eggs in New York City.
The pair were arrested on Tuesday on federal charges of conspiracy to commit money laundering and conspiracy to defraud the United States. They stand accused of laundering $4.5bn worth of Bitcoin acquired in the hack of the Bitfinex exchange in 2016. If they are convicted, they could go to prison for up to 25 years.
