What is Gemini?
Gemini is a centralized cryptocurrency exchange and custodian founded in 2014 by Cameron and Tyler Winklevoss. It supports 74 coins and 81 trading pairs, alongside custody, advanced trading and prediction-market products. The business operates as a New York trust company under a Limited Purpose Trust Charter.
Ownership and funding
Gemini is headquartered in New York City. Cameron Winklevoss and Tyler Winklevoss are its co-founders. The company raised $400 million in November 2021 at a reported $7.1 billion valuation, with participation from D1 Capital Partners and other investors. Its wider product range includes Gemini Custody, Gemini Clearing and the Gemini Credit Card.
How Gemini works
The exchange lets customers buy, sell and trade digital assets through a standard interface or ActiveTrader. Gemini says customer funds are held 1:1 through periodic proof-of-reserves reports. Its custody model uses offline storage, while security controls include hardware security-key support for two-factor authentication and withdrawal-address allowlisting.
Gemini Predictions offers yes-or-no contracts linked to event outcomes. A correct position pays $1.00 per contract when the event resolves. The platform also supports Gemini dollar, a stablecoin launched for trading in September 2018.
Fees and availability
The standard interface charges a 1.49% transaction fee plus a 1.00% convenience fee. ActiveTrader uses maker-taker pricing, starting at 0.20% for makers and 0.40% for takers, with lower rates at higher 30-day trading volumes. Product availability can vary by jurisdiction.
Track record and risks
Gemini went live as an exchange in October 2015 and received its New York trust charter that month. It received crypto registration in France in January 2024 and moved its European headquarters from Dublin to Malta in January 2025. Reported controls include SOC 1 Type 2, SOC 2 Type 2 and ISO 27001 certifications.
Gemini Earn shut down in January 2023 after Genesis suspended withdrawals in November 2022. The Securities and Exchange Commission charged Gemini and Genesis in January 2023 over the alleged unregistered offer and sale of securities through Earn. A 2022 dataset involving some Gemini customers was traced to a third-party Twilio Authy incident rather than Gemini's systems. The Commodity Futures Trading Commission sued Gemini in June 2022 over alleged misrepresentation and announced a $5 million settlement in January 2025 over alleged misleading statements about a bitcoin auction.

Our review
3.4/5
Fair
Gemini combines NYDFS oversight, custody controls and proof of reserves with clear ActiveTrader fees, but its past Earn failure and standard-interface costs weaken the case.
Gemini is a centralized exchange and custodian founded in 2014 by Cameron and Tyler Winklevoss. Its main regulatory distinction is a New York Department of Financial Services Limited Purpose Trust Charter, and it received crypto registration in France in January 2024. The company moved its European headquarters from Dublin to Malta in January 2025.
Fees depend heavily on the interface. The standard interface charges a 1.49% transaction fee plus a 1.00% convenience fee. ActiveTrader starts at 0.20% maker and 0.40% taker, with lower rates at higher 30-day volume. The exchange has stop limit orders, and the standard product supports buying, selling and trading digital assets. Current listed data records 74 coins and 81 trading pairs.
Security controls include proof of reserves showing customer funds held 1:1, cold storage, hardware security keys, withdrawal address allowlisting, and SOC 1, SOC 2 and ISO 27001 certifications. A 2022 dataset involving some customers was traced to a third-party Twilio Authy incident rather than a breach of Gemini's systems.
Gemini Earn is a notable part of the exchange's product history. The product shut down in January 2023 after Genesis suspended withdrawals in November 2022. The SEC charged Gemini and Genesis over the alleged unregistered offer and sale of securities, while the CFTC sued Gemini in 2022 and the company reached a $5 million CFTC settlement in January 2025 over alleged misleading statements about a bitcoin auction.
Gemini offers a regulated US exchange, custody services, proof of reserves and an advanced trading interface. Active traders can avoid the standard interface's higher stated charges. Its listed products center on spot trading, custody and prediction markets, while Gemini Earn has ended.
