He made the same mistake Madoff did
Also what the fuck are you talking about here? Madoff turned himself in because no one in the SEC would look at the DTCCs books. Not to mention his other fleece of payment for order flow is now an industry standard for almost all brokers and market makers.
Hate to break it to you, ftx’s biggest scam was in tokenized securities still being traded today and being used as free locates for market makers without any real shares backing these things. Wall Street is so fucking corrupt its not even funny.
