Gemini is a cryptocurrency exchange that was founded in 2014 by twin brothers Cameron and Tyler Winklevoss. The Winklevoss brothers are well-known for their involvement in the early days of Facebook, where they famously sued Mark Zuckerberg for allegedly stealing their idea. After receiving a settlement from Facebook, the brothers invested heavily in Bitcoin and other cryptocurrencies, eventually leading them to create Gemini. The exchange is known for its focus on security and regulatory compliance, and has become a popular choice for institutional investors.

Gemini launched in October 2015, after receiving approval from the New York State Department of Financial Services. The exchange was one of the first to receive a BitLicense, which is a regulatory framework for virtual currency businesses in New York. Since then, Gemini has expanded its offerings to include a variety of cryptocurrencies, including Bitcoin, Ethereum, Litecoin, and Bitcoin Cash. The exchange has also launched a number of new products, such as Gemini Custody, which allows institutional investors to securely store their digital assets.

Gemini is headquartered in New York City, and has offices in Chicago, Portland, and London. The exchange is regulated by the New York State Department of Financial Services, and is subject to strict security and compliance standards. Gemini has also partnered with a number of other companies in the cryptocurrency space, such as Nasdaq and CBOE, to help bring more institutional investors into the market. Overall, Gemini has become a trusted and reliable platform for buying, selling, and storing cryptocurrencies, and is likely to continue to play an important role in the industry for years to come.
