Sam Bankman-Fried's fraud trial has given an unprecedented window into how a group of graduates from elite US universities in their late 20s and early 30s tried, and ultimately failed, to avert one of the biggest and swiftest corporate meltdowns ever. Now, the former billionaire's fate could hinge on how jurors view his actions in the 10 days before the FTX cryptocurrency exchange's collapse nearly one year ago. Prosecutors say Fried used customer funds to pay lenders to his Alameda Research hedge fund, and that his false assurances to customers were a critical part of his fraud scheme.
