When Sam Bankman-Fried’s cryptocurrency exchange collapsed in November, one of his oldest friends sent him a message of support.
“I love you, Sam,” said Adam Yedidia, a college classmate of Mr. Bankman-Fried’s who went on to work for him at the exchange, FTX. “I am not going anywhere. Don’t worry.”
Within days, Mr. Yedidia had resigned from FTX. And last week, at Mr. Bankman-Fried’s fraud trial in federal court in Manhattan, Mr. Yedidia showed up to testify for the prosecution, and recounted the conversation to the jury.
