While that's true, if you have a good understanding of bankruptcy law, and a reasonable understanding of what assets FTX owned you could make a reasonable guess of how much money the eventual bankruptcy would pay out. Since the administrators publicly published what assets there were quite early on I think it's fair to say $270k always looked like a good deal.
