Several cryptocurrency billionaires recorded major wealth declines in 2025 following sharp volatility across digital asset markets, according to a new report.
Data from the Bloomberg Billionaires Index showed that losses were concentrated after a severe crypto market slide in October.
Strategy executive chairman Michael Saylor was among the biggest losers, with his net worth falling sharply over the past year.
Bloomberg reported that Saylor lost $2.6 billion in the last 12 months, reducing his estimated net worth to $3.8 billion.
Strategy’s Bitcoin treasury strategy] generated huge returns through early October, when Bitcoin hit fresh highs. However, things began to turn south soon after as a slump in Bitcoin’s value sent Strategy’s stock price plunging by more than half, dragging Saylor’s net worth down nearly $6 billion from its high-water mark in the process.
Bloomberg said.
Gemini co-founders Cameron and Tyler Winklevoss also suffered significant losses during the same period.
Bloomberg said the Winklevoss twins saw their combined wealth decline by 59% since the beginning of the year.
Former Binance chief executive Changpeng “CZ” Zhao was also affected by the market downturn.
