Ilya Lichtenstein is in the spotlight. He’s the mastermind behind one of the biggest cryptocurrency heists ever. U.S. prosecutors are asking for a five-year prison sentence for his role in a money-laundering scheme linked to the $6 billion hack of the Bitfinex exchange.

Lichtenstein pleaded guilty last year. Now, prosecutors believe he deserves a longer sentence than his wife, Heather Morgan. She’s also involved in this case. Morgan, who calls herself the “Crocodile of Wall Street,” is facing a recommendation of 18 months in prison.

This case highlights the serious consequences of cybercrime. Prosecutors are making it clear that they take these offenses seriously. They aim to hold those responsible accountable for their actions.
