"Bankman-Fried told me that as many as five of his colleagues at FTX were billionaires. And that was just a single crypto company. Many unprofitable start-ups with questionably legal business plans were valued in the billions. Changpeng Zhao, who founded another crypto exchange called Binance, made a fortune estimated at $96 billion. The numbers got so large that even the most delusional crypto fantasies started to sound reasonable. It seemed like nothing could stop crypto’s manic rise. Until, of course, the house of cards collapsed. Starting in the summer of 2022, many companies in crypto were revealed to be frauds. The bubble popped. About $2 trillion of market value was erased. Billionaires went bankrupt. Millions of ordinary people lost their savings. The financial authorities who’d allowed scammers to run rampant finally decided it was time to lay down the law. Bankman-Fried and many of his associates were arrested. Crypto didn’t disappear entirely, but the fever had broken."
