In a courtroom drama minus the jury, Sam Bankman-Fried (SBF) took the stand for what can be best described as a \u201ctest run.\u201d The hearing aimed to help the judge decide what evidence will be admissible in the actual trial. SBF's performance under Assistant U.S. Attorney Danielle Sassoon's questioning was less than stellar. His verbose answers and frequent apologies contrasted sharply with Sassoon's pointed questions, at times making him appear evasive. The hearing also touched on SBF's use of encrypted messaging app Signal and his company's data retention policy.\nCatch up on Unchained\u2019s previous coverage:\xa0\n\nSBF Trial, Day 1: Possible Witnesses Include FTX Insiders, Big Names in Crypto, and SBF\u2019s Family\n\nSBF Trial, Day 2: DOJ Says Sam Bankman-Fried \u2018Lied\u2019 While Defense Claims His Actions Were \u2018Reasonable\u2019\n\nSBF Trial, Day 3: Why a True Believer in FTX Flipped Once He Learned One Fact\n\nSBF Trial, Day 4: SBF\u2019s Lawyers Annoy Judge Kaplan, While Wang Reveals Alameda\u2019s Special Privileges\n\nSBF Trial, Day 5: SBF's Defense Finally Found Its Legs, But Can It Counter Caroline Ellison?\n\nSBF Trial, Day 6: Caroline Ellison Recalls 'The Worst Week of My Life'\n\nSBF Trial, Day 7: In SBF Trial, Did the Defense Lose Its Opportunity With the Star Witness?\n\nSBF Trial, Day 8: Former BlockFi CEO Adds Credibility to Fraud Charges\n\nSBF Trial, Day 9: Nishad Singh Describes Former FTX CEO as a Bully and Big Spender\n\nSBF Trial, Day 10: Defense Struggles to Discredit Nishad Singh's Testimony\n\nSBF Trial, Day 11: How Alameda Got FTX Into a $9 Billion Hole\n\nSBF Trial, Day 12: Former FTX General Counsel Speaks Out Against SBF\n\nDid Sam Bankman-Fried Have Intent to Defraud FTX Investors?\n\nWhy These Lawyers Say It's Over for SBF-But His Only Hail Mary Is to Testify\n\nHere\u2019s How Sam Bankman-Fried\u2019s High-Stakes Trial Could Play Out\n\nSBF Trial: How Sam Bankman-Fried\u2019s Lawyers Might Try and Win His Case\n\nThe High-Stakes Trial of Sam Bankman-Fried Begins: What to Expect\n\n\nLearn more about your ad choices.
