Nishad Singh, a former FTX’s engineering director, has reportedly pleaded guilty to six counts of criminal charges and agreed to cooperate with prosecutors to investigate the crypto exchange founder Sam Bankman-Fried. Singh admitted that he knew Alameda Research, which was Bankman-Fried’s hedge fund, was borrowing FTX customer funds without their knowledge. Singh is the third Bankman-Fried close associate to plead guilty and assist the probe. He is also facing civil lawsuits filed by the US Securities and Exchange Commission and the Commodity Futures Trading Commission.
