Morgan also pleaded guilty last year to one count of conspiracy to commit money laundering. She is due to be sentenced on 18 November.

According court documents, Lichtenstein used advanced hacking tools and techniques to hack into Bitfinex.

Following the hack, he enlisted Morgan’s help to launder the stolen funds.

The methods included using fictitious identities, switching the funds into different cryptocurrencies and buying gold coins.

Lichtenstein, who was born in Russia but grew up in the US, would then meet couriers while on family trips and move the laundered money back home, prosecutors said.
