The 50 Most Interesting Companies In Bitcoin's History: 27/50

Gemini

Founded by Cameron Winklevoss, Tyler Winklevoss 2014 · Exchanges · Active

The Idea: A regulated, compliance-first Bitcoin exchange. The twins used part of their $65M Facebook settlement to buy $11M in Bitcoin in 2013, then built Gemini as the 'adult in the room' for serious bitcoin investors, while also releasing the Gemini credit card, which offers bitcoin rewards on purchases.

Early Traction: The Winklevoss twins filed the first-ever Bitcoin ETF application with the SEC in 2013. While it was rejected, it kicked off a decade-long fight that ultimately led to spot ETF approval in 2024.

Peak Stats: IPO'd on NYSE in September 2025 at $28/share.

Status Today: Active and publicly traded. The twins also backed BitInstant in 2012 (Shrem's company), making their arc one of the most complete in Bitcoin history, from early angel investor to exchange operator to public company.

Why It Matters:

One of the oldest exchanges, and pivotal in the ultimate approval of the first spot bitcoin ETFs.
