Heather Morgan and Ilya Lichtenstein: All the latest on the NYC couple arrested over alleged Bitfinex $4.5B bitcoin-laundering plot

• A husband and wife in Manhattan have been accused of laundering $4.5 billion in stolen bitcoin.
• Agents found hollowed-out books, encrypted devices, and $40,000 in cash at their apartment.

A New York couple have been accused of taking part in a $4.5 billion plot to launder stolen bitcoins.

Heather Morgan, 31, and her husband Ilya Lichtenstein, 34, were indicted by the US Department of Justice on Tuesday, with investigators alleging they took part in a sophisticated, years-long scheme to launder the proceeds from the hack of cryptocurrency exchange Bitfinex in 2016.

The couple are entrepreneurs with deep ties to the tech industry, founding multiple startups over the year — but it's their social media activity that has attracted the most attention. Morgan also performed as a rapper, specializing in surreal and unconventional rhymes about finance and her lifestyle.

Morgan and Lichtenstein have been transferred to custody in DC, and will appear in court on Monday when a judge assesses their requests for bail and whether they pose a flight risk.

What to know about the Bitfinex hack:

Bitfinex is a cryptocurrency exchange registered in the British Virgin Islands. In August 2016, hackers managed to breach its security systems and stole roughly 120,000 bitcoin from its customers. The stolen bitcoin was worth roughly $70 million at the time, when the price of bitcoin was around $600.

Bitfinex said at the time that all of its customers would lose 36% of their funds to account for the losses. It also created special digital tokens that recorded customers' losses. Some of the tokens could exchanged for shares of iFinex, the company that operates Bitfinex, while other tokens could be redeemed if the stolen bitcoins were recovered in the future.

The US Department of Justice has said it will create a special court process for victims of the hack to reclaim their stolen bitcoin.

The hackers have never been identified. Morgan and Lichtenstein are accused by federal prosecutors of laundering the bitcoin stolen from Bitfinex, but not of actually stealing the bitcoin in the hack.
