Gemini’s history

Gemini cryptocurrency exchange started its activity in 2015 in the USA. The founders are the Winklevoss brothers, who focused on the best cryptocurrency exchanges and made Gemini a fully regulated international exchange. The platform started operating after the New York State Department of Financial Services approved such activities.

The exchange works with private traders and institutional investors. The exchange’s interface is available only in English, because it is designed for large players from developed countries (USA, Canada, Hong Kong, Singapore, South Korea, UK). Notably, Gemini was the first who launched BTC on Winkdex Bitcoin index.

Deposits are credited to the account instantly, without waiting for confirmation of the transfer record in the blockchain.

The brothers have built an institutional-level infrastructure. As a New York-based trust company, they are licensed to provide digital asset exchange and custody services.

The exchange is fiduciary and takes into account capital reserve requirements, cybersecurity requirements and bank compliance standards set by the NYS Department of Financial Services and NYS banking laws.

The Gemini Marketplace conducts auctions for certain trading pairs every day (including weekends and holidays) that promote liquidity and price discovery.

Connection options meet the needs of all traders. They include REST, WebSockets and FIX via cross-connect from Equinix NY4 or NY5 data centers. You can use these protocols to access public market data as well as closed trading sessions.

A real-time, dynamic betting schedule builder provides a transparent and incentive-based trading experience.

Deposit accounts meet the needs of large and active traders looking for a secure place to store digital assets before and after a trade.

Segregated deposit accounts are ideal for institutional customers such as hedge funds, mutual funds and exchange-traded funds who may be required by law to keep their digital assets with a licensed custodian such as Gemini.

All dollar deposits are held at FDIC-insured banks. Most digital assets are saved offline in Cold Storage’s proprietary system.

Gemini serves a wide range of customers including individuals, institutions, algorithmic traders, private traders, market makers, investment firms, hedge funds and various digital asset companies.
