Sam Bankman-Fried, the American crypto entrepreneur who went from billionaire to bankrupt, is on trial in New York for fraud.

The 31-year-old who founded the cryptocurrency exchange FTX is accused of lying to investors and lenders.

He has denied those charges, and instead says he was acting in good faith but made mistakes. He says he never set out to defraud anyone.

In the coming days, 12 jurors will decide his fate - he could face a life sentence in prison if convicted.

Vivienne Nunis speaks to financial journalist Michael Lewis, who spent hundreds of hours with Sam Bankman-Fried for his new book Going Infinite.
