The billionaire CEOs of major crypto exchanges saw their personal fortunes diminish as Bitcoin (CRYPTO: BTC) and the wider crypto market extended losses this week.

What Happened: A report from Bloomberg on Wednesday details significant declines in worth for some of the biggest names in the crypto industry.

Coinbase Global Inc (NASDAQ:COIN) CEO Brian Armstrong’s personal net worth dropped from as much as $13.7 billion in November to under $2.2 billion this week, as per the Bloomberg Billionaires Index.

Coinbase is now trading 84% lower than its Nasdaq debut last year. The firm ended its first day of trading with an $85.7 billion valuation and the direct listing reportedly created 1,000 millionaires.

Another crypto exchange CEO that saw his fortune sink was Binance founder Changpeng Zhao or “CZ.” In January, CZ’s estimated net worth was a whopping $96 billion — a figure that has now shrunk to $11.6 billion.

Gemini founders Tyler and Cameron Winklevoss each lost $2.2 billion of their wealth this year. According to Bloomberg, this figure equates to around 40% of their net worth.

Sam Bankman-Fried, CEO of crypto exchange FTX, has lost 50% of his wealth since the end of March. Over the course of a few weeks, Bankman-Fried’s wealth has fallen to $11.3 billion.
