Report: Cryptocurrency Billionaires of 2025 Among Biggest Losers

Jan 1, 2025 (Bloomberg) — The Bloomberg Billionaires Index shows many prominent cryptocurrency industry figures incurred heavy losses in 2025, driven by factors including the October crypto market “flash crash.” Strategy Chairman Michael Saylor saw his net worth shrink by $2.6 billion over the past 12 months, now standing at $3.8 billion. Bloomberg noted Strategy’s Bitcoin treasury strategy delivered significant returns before Bitcoin hit a new high in early October, but the subsequent price drop sent Strategy’s stock tumbling more than 50% from its peak—pushing Saylor’s net worth down nearly $6 billion from its all-time high. Gemini co-founders Cameron and Tyler Winklevoss, along with CZ, also suffered major asset losses amid the sharp October crypto market decline. Bloomberg reports CZ’s net worth has fallen by about 5% (roughly $50.9 billion) since Jan 1, 2025, while the Winklevoss brothers’ assets have shrunk by 59% over the same period. Still, global billionaires added roughly $2.2 trillion to their wealth in 2025, with 8 individuals accounting for 25% of that gain. By contrast, crypto industry professionals’ overall performance lagged far behind. An exception: Circle CEO Jeremy Allaire’s net worth has jumped about 149% since June 4, boosted by the U.S. passing the “GENIUS Act” for stablecoin payments.
