NEW YORK, Nov 2 ― FTX founder Sam Bankman-Fried's defence lawyer told jurors yesterday that prosecutors in his fraud trial sought to portray him as a "villain” and a "monster” because they could not prove he stole billions of dollars from the cryptocurrency exchange's customers.

Attorney Mark Cohen's closing argument in Bankman-Fried's trial in Manhattan federal court came after the prosecution urged the 12 jurors to convict Bankman-Fried, arguing he stole US$8 billion (RM38.2 billion) out of simple greed in one of the biggest financial frauds in US history.

Cohen said prosecutors elicited testimony about Bankman-Fried's sex life and appearance ― the former billionaire was known for his unkempt mop of curly locks and wearing shorts and T-shirts ― to try to get the jury to dislike him.

"Time and again, the government has sought to turn Sam into some sort of villain, some sort of monster,” Cohen said. "And let's face it, an awkward high school math nerd doesn't look particularly villainous. So what did they do? They wrote him into the movie as a villain.”

In his closing argument, prosecutor Nicolas Roos said Bankman-Fried directed other FTX executives to alter the exchange's computer code to allow a hedge fund he owned, Alameda Research, to siphon customer money.

"This was a pyramid of deceit built by the defendant on a foundation of lies and false promises, all to get money,” Roos said. "He had the arrogance to think he could get away with it.”

Jurors are expected to begin deliberations today after prosecutors give a rebuttal argument, meaning Bankman-Fried may learn his fate just shy of one year after FTX filed for bankruptcy in a swift corporate meltdown that shocked financial markets and wiped out what had been his estimated US$26 billion fortune.

The defence rested its case on Tuesday after Bankman-Fried underwent a second day of tough cross-examination by the prosecution ― the risk he ran by opting to testify in this own defence. Bankman-Fried, who pleaded not guilty to two counts of fraud and five counts of conspiracy, tried over three days of testimony to convince the 12 jurors of his innocence.

In all, the jury heard 15 days of testimony. Three of Bankman-Fried's former close confidantes, testifying for the prosecution after entering guilty pleas, said he directed them to commit crimes, including helping Alameda loot FTX and lying to lenders and investors about the companies' finances.

Alameda used that money to pay off its lenders and to lend to FTX executives so they could make speculative investments and donate to US political candidates, prosecutors say.

Under questioning from Cohen, Bankman-Fried portrayed himself as a busy CEO who left operational nuts and bolts to subordinates. He made mistakes that harmed customers and employees, Bankman-Fried admitted, but never defrauded anyone or stole money.

"Poor risk management is not a crime,” Cohen said on Wednesday. "The question of whether Sam's business judgment was reasonable, even if it later turned out to be mistaken, is not a criminal one.”

Roos argued Bankman-Fried's digital fingerprints undermined the argument that he acted in good faith. Roos said Bankman-Fried had looked at a document as far back as June 2022 showing that Alameda had a large negative balance on FTX, as well as a spreadsheet Alameda's CEO Caroline Ellison - a prosecution witness - planned to send to lenders that hid its debts to FTX.

"As a result of sending out those fake balance sheets they got new loans,” Roos said, adding that the financial statement hid the "crime-y, fraud-y parts” of Alameda's balances.

Bankman-Fried could face decades in prison if convicted on all counts. He has been jailed since August after Kaplan revoked his bail, having concluded he likely tampered with witnesses. ― Reuters
