In the memo, Bankman-Fried called Alameda's failure to hedge its bets a "mistake." When Everdell asked if the decision not to hedge was Ellison's, Wang replied that she was Alameda's CEO at the time. Prosecutors said last week they planned to call Ellison to take the stand once Wang finishes his testimony. She was seen entering the courthouse on Tuesday morning wearing a blue baseball cap and sunglasses, and carrying a blue thermos. A third former member of Bankman-Fried's inner circle, ex-FTX engineering chief Nishad Singh, is also expected to testify at trial.
