I just stumbled across something interesting that the crypto community probably should be talking about more. The release of Jeffrey Epstein’s emails and documents sheds an entirely new light on Bitcoin’s early history—and how this financier, despite his convicted crimes, worked behind the scenes to shape cryptocurrency policy.

Who was this guy, anyway? Epstein was a U.S. investment banker with an enormous network in finance, science, and politics. What many people don’t know: he took an early interest in the emerging crypto market and used his connections to exert influence—up until his arrest in 2019.

What’s interesting is just how deeply involved he actually was. Leaked emails from 2015–2017 show that Epstein played a central funding role in the Bitcoin Core development—specifically through the MIT Media Lab. After the original Bitcoin Foundation collapsed, the MIT Digital Currency Initiative (DCI) became a critical lifeline for leading Bitcoin developers. Joi Ito, who was then the head of the MIT Media Lab, thanked Epstein directly for so-called “Gift Funds,” enabling quick support for Bitcoin Core staff. This was at a time of great uncertainty in the industry—so Epstein’s money arrived exactly at the right moment.

But that’s where things get problematic: MIT tried to conceal Epstein’s donations. The university declared them anonymous and hid their true origin. On top of that was Leon Black, a private equity CEO, whose million-dollar donations to MIT were later linked to Epstein. This non-transparent funding structure ultimately led to Joi Ito’s resignation and sparked fierce criticism of the institution’s integrity. While there’s no indication that Epstein influenced technical Bitcoin decisions, the lack of transparency was—and remains—ethically questionable.

In addition to funding, Epstein was also politically active. In emails from February 2018, he argued for stricter crypto taxation and regulatory clarity. He reached out to Steve Bannon and sought contact with the U.S. Department of the Treasury. Epstein supported a voluntary disclosure program so Americans could report their crypto gains—and he spoke out in favor of taxes on everyday Bitcoin transactions, such as when buying furniture. He also thought globally: he sharply criticized Facebook’s Libra project and warned about the lack of international oversight over digital assets. Without early regulation, he warned, cryptocurrencies could pose a “systemic risk.”

What fascinates me about this story is that Epstein recognized the transformative potential of Bitcoin and cryptocurrencies much earlier than most political and scientific decision-makers. At the same time, the MIT controversy shows how important transparency and accountability are when it comes to funding innovation—especially for projects like Bitcoin, which has decentralization and independence at its core. The irony is sharp: a financier with a dark past played a role in the early history of Bitcoin, while the institutions that benefited from his donations compromised their transparency. A sobering lesson at the intersection of finance, technology, and institutional ethics.
