Recently unsealed files have revealed Jeffrey Epstein's connections with key figures in the cryptocurrency industry during its early days. Documents from January 30 show Epstein's participation in the $18 million seed round of Blockstream, a Bitcoin infrastructure company, in 2014. His investment increased from $50,000 to $500,000 through the MIT Media Lab's Joi Ito fund, with involvement from co-founder Austin Hill and Bitcoin pioneer Adam Back. The files also disclose Epstein's interactions with notable figures such as Peter Thiel, discussing Bitcoin's definition in 2014, and proposing an Islamic cryptocurrency to a Saudi royal advisor in 2016. Despite describing Bitcoin as "clever but with serious flaws" in 2011, he later dismissed it as not worth buying in 2017. The U.S. Department of Justice confirmed no evidence of Epstein using cryptocurrency for illicit activities, noting his role was limited to networking and occasional investments.
