Jeffrey Epstein invested early in major crypto firms, notably putting $3 million into Coinbase in 2014 after being introduced by Tether co-founder Brock Pierce, though the investment was made independently. Epstein also invested in Blockstream through his association with Joi Ito’s fund. His contacts included prominent figures such as Blockstream co-founder Adam Back and Coinbase’s Fred Ehrsam. Regular communications occurred with Pierce, post-2008 conviction, discussing crypto and arranging meetings; emails reference Epstein facilitating introductions and social encounters with Pierce. Epstein also met with former Harvard president Larry Summers and Pierce to discuss Bitcoin. He sought clarity on crypto regulation and taxation, advocating for voluntary disclosure forms and likening crypto regulation to coordinated international internet agreements. Files show interaction with Michael Saylor, who was criticized by Epstein’s circle long before his company’s large BTC purchases. Epstein questioned Bitcoin’s purpose in correspondence with Peter Thiel. Though Ethereum’s Vitalik Buterin was mentioned in Epstein’s emails, there was no direct connection. Despite his criminal convictions, Epstein expressed concern about ethical considerations when funding crypto projects, warning against investing in "dangerous" or ethically questionable ventures.
