Hedge fund manager Michael Burry, famed for forecasting the 2008 financial crisis, says the problem with auditing cryptocurrency exchanges, like Binance and FTX, is the same as when he started using a new kind of credit default swap. “Our auditors were learning on the job,” he described, adding that it’s “not a good thing.”

Commenting on accounting firm Mazars Group halting proof-of-reserve (POR) audits for crypto companies, Burry tweeted:

This is the problem. In 2005 when I started using a new kind of credit default swap, our auditors were learning on the job. That’s not a good thing. Same goes for FTX, Binance, etc. The audit is essentially meaningless.
