Gemini is a next-generation cryptocurrency exchange and custodian that allows customers to buy, sell, and store digital assets like Bitcoin and Ethereum. Founded by Cameron and Tyler Winklevoss, Gemini differentiates itself by being a 'security-first' and highly regulated platform. It was the first U.S. exchange to be licensed as a New York trust company, meaning it adheres to strict banking standards and capital reserve requirements. Their motto is 'Ask for Permission, Not Forgiveness,' positioning them as the safe, compliant alternative to riskier offshore exchanges.
