The leader of a Miami crew charged by the U.S. Department of Justice (DOJ) with defrauding banks in a 2020 cryptocurrency-related scheme has pleaded guilty, an official notice from Wednesday said.

The scheme saw U.S. banks processing more than $4 million in false reversals, while a cryptocurrency exchange lost around $3.5 million worth of digital assets, the DOJ's notice said.

Cabrera, a 26-year-old from Miami Florida, pled guilty to "one count of conspiracy to commit wire fraud," which comes with a 20-year prison sentence, and has agreed to pay restitution of $3.6 million – with an additional forfeiture of $1.2 million.
