The US Justice Department announced on Tuesday it had recovered a record sum of more than 94,000 bitcoin – currently valued at US$3.6 billion – stolen from a Hong Kong virtual exchange in 2016. A couple accused of seeking to launder the bitcoin were arrested in New York, the department said. Ilya Lichtenstein, 34, and his wife Heather Morgan, 31, appeared in federal court over the charges and were granted bail by the judge. When the judge indicated she would set a bond, the government requested it be set at US$100 million, an amount one of the defence lawyers called “laughable”. The judge set bail for Morgan at US$3 million and asked her parents to post their home as security. For Lichtenstein, bail was set at US$5 million. Lichtenstein and Morgan face 20 years in prison for the money laundering charges. In addition, they could receive an additional sentence of up to five years for conspiracy to defraud the US, according to the Justice Department statement. Lichtenstein and Morgan allegedly sought to launder the proceeds of 119,754 bitcoin – then valued at US$65 million – that were stolen during a 2016 hack of the virtual currency exchange Bitfinex.

Prosecutors said some of the stolen cryptocurrency was sent to a digital wallet controlled by Lichtenstein, who describes himself on social media as a “technology entrepreneur, coder and investor”. About 25,000 of the stolen bitcoin were transferred out of the wallet over the next five years “through a labyrinth of cryptocurrency transactions”, and some of the funds were deposited into accounts the couple opened online, including by using false identities. One of Morgan’s aliases is “Razzlekhan”. A video posted online under that name shows a young blond woman rapping near the New York Stock Exchange. In the song, the woman refers to herself as a “crocodile of Wall Street” and a “risk-taker”.

The funds were used to buy items such as gold or digital NFTs (non-fungible tokens), according to US officials. The remaining bitcoin, now valued at US$3.6 billion, was recovered last week by US investigators. They executed a search warrant to scour the couple’s online accounts and were able to recover the security key that gave them access to the digital wallet. Bitfinex has offered a multimillion-dollar reward for information leading to the recovery of the stolen funds, but the Justice Department declined to say whether that played a role in the arrest of Lichtenstein and Morgan. Authorities had called on victims of the initial theft to come forward to recover their losses. The investigation continues, the Justice Department said, declining to comment on who was behind the initial hack. Bitcoin has existed since 2008 and has seen significant price fluctuations since then. The cryptocurrency attracts big names in finance but, according to US authorities, allows criminal networks to make their financial flows more opaque. This case “demonstrates once again that we can follow money through the blockchain”, said assistant attorney general Kenneth Polite Jnr, referring to a decentralised technology for storing and transmitting information, “and that we will not allow cryptocurrency to be … a zone of lawlessness within our financial system”. Morgan, who was born in Oregon and grew up in California, has foreign ties, the prosecutor said. She has lived in Hong Kong and Egypt and is studying Russian, according to her social media. She’s a journalist and economist and travels internationally for work, according to the government. Lichtenstein moved to the US at the age of six to escape religious prosecution. He grew up in the suburbs of Chicago, where his mother was a biochemist at Northwestern University. Additional reporting by Bloomberg
