The Gemini software platform enables developers and organizations to move any business or application onto a blockchain. The Gemini dollar (GUSD) allows for frictionless transactions between traditional currency and the emerging cryptocurrency asset class.

Gemini is a cryptocurrency exchange designed to bring cryptocurrencies to the masses. The Gemini Exchange was founded in 2014 by Tyler and Cameron Winklevoss, among the first major investors in Bitcoin, via their venture capital firm Winklevoss Capital. They are also well known for suing Mark Zuckerburg over the claim that he stole their ConnectU idea as the basis for Facebook.

The Gemini Exchange is a Bitcoin and Ethereum exchange that operates in the United States, Canada, Hong Kong, Japan, Singapore and South Korea. This review will focus on their Bitcoin exchange service since this is most relevant to X.B.T.

• The Gemini cryptocurrency exchange was founded to ensure an optimal trading experience. Gemini puts a great deal of effort into security and compliance measures to achieve this. In addition to receiving a full license from the New York State Department of Financial Services (NYSDFS), Gemini adheres to all applicable federal and state regulations in its operations.

• In May 2017, Gemini extended its services to the U.K. and Canada thanks to a strategic partnership with an Irish payment provider, Cubits. In December 2017, the exchange partnered with Cboe Global Markets – one of the world's largest regulated exchanges – to launch a bitcoin futures contract.

• Cameron Winklevoss also commented on plans to add more cryptocurrencies and eventually enable users to trade between different digital currencies:

• "We are thinking about other types of digital assets. There are a lot of interesting things happening with all the P2P (peer-to-peer), sharing economies, and IoT (Internet of Things) as well. We feel this has been something missing in the digital asset ecosystem, and we plan to build it. We would like to add support for other cryptocurrencies, but we aren't really focused on that right now. If consumers trade ether coins, for example, we would absolutely add those."

• A recent report by Bloom revealed that Gemini's daily trading volume has been increasing rapidly. The exchange has been experiencing a trading volume of around USD 50 to 100 million per day, roughly the same as other high-volume cryptocurrency exchanges such as Kraken and Bitfinex.

• In January 2018, Gemini announced that it was adding support for more cryptocurrencies due to increasing demand from its customers. In particular, Ethereum Classic (E.T.C.) and Litecoin (L.T.C.) were announced, with more to be added in 2018.

• Gemini's customer base is also growing steadily, which has been reflected in the daily trading volume increase. The exchange has stated that it now has 13 million customers, up from around 1.6 million in April 2017.

• Decentralized Ethereum token exchange owned by the community, implemented in a regulated and licensed financial institution.

• Both fiat currency (USD, E.U.R., GBP, CNY) and cryptocurrency deposits accepted - next cryptocurrencies supported: Bitcoin Cash, Litecoin and Zcash.

• ETH, L.T.C. and B.C.H., and USD deposits, are free, but there is a fee for all other currencies. Deposits are processed within 1-2 business days.

• BTC withdrawals incur a 0.001 BTC network mining fee (regardless of withdrawal amount). At a minimum, 2 confirmations are required for deposits to be credited.

• Ethereum, Litecoin and Zcash withdrawals are processed within 1-2 business days.

• Gemini customer support operates on weekdays from 9 AM to 5 PM EST, excluding the following U.S. holidays: New Year's Day, Martin Luther King Jr. Day, President's Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas.

• Gemini accounts are protected by OAuth 2.0 with Google Authenticator.

• Two-factor authentication is mandatory for all accounts but can be temporarily suspended during login through the Google Authenticator app (make sure your key is backed up beforehand).

• I.P. address safe listing available. Requests coming from unwhitelisted locations will be denied.

• WebSocket and REST API are available for trading bots.

• Gemini is a regulated financial institution - registered with the New York State Department of Financial Services (NYSDFS). As such, user information is protected by the Federal Information Security Management Act (FISMA) and the Gramm-Leach-Bliley Act (GLBA).

• Gemini exchange is insured by the FDIC, up to $250,000 per customer.

• Gemini operates within a secure data center and has taken multiple precautions to ensure the security of user funds. Secure cold storage solutions are implemented for cryptocurrency storage.

• Gemini will be the first fully regulated, fully electronic currency to link directly with your bank account in the U.S.A. Gemini is a next-generation bitcoin exchange built by entrepreneurs who have made millions of dollars on bitcoin. The founders believe that what makes bitcoin successful is its revolutionary technology and fair access to the cryptocurrency. We are convinced that the only way to truly realize bitcoin's potential is by following a strict set of rules and regulations. We believe in indelible transactions, holding client funds separate from company operational funds, and always being transparent with our customers.

• You can prepay with cash or credit card and get your favorite bitcoin to treat in return. No Fees. No Hassles. Your Trusted Digital Asset Exchange: We have worked relentlessly to bring Gemini to life for the last two years. Operating a money transmitter entails substantial regulatory, I.T., and financial challenges.

• To ensure that your money is safe, we store 100% of all customer U.S. dollars in FDIC-insured banks located within the continental United States. These funds are not accessible or even visible to us, ensuring complete separation of customer fiat balances from company operational funds required by regulation. When a withdrawal request is submitted, we instantly remove funds from one of our FDIC-insured banks and deliver the U.S. dollars to the institution's bank account processing your request (INT Health Services, for example).

• Additionally, no customer can withdraw or deposit fiat via a wire transfer for regulatory reasons. Only approved institutions regulated by the New York State Department of Financial Services (NYSDFS) are allowed to submit wire transfers on the customer's behalf.

• Zero Fees. Exchange without Limits: There are no fees for deposits or withdrawals of U.S. dollars, bitcoin, or Litecoin onto Gemini. This is possible because we've chosen not to hold client fiat or digital currency deposits. All orders placed on Gemini are always open to immediate execution, allowing our customers to trade seamlessly.
