Gemini is a large cryptocurrency exchange that can sit comfortably next to some of the other larger exchanges on the market. With the continued growth of the crypto exchange market, it can be difficult to know which one to trust and which one to ignore. Let's be honest, we don't have time to go from site to site reading about small details of all exchanges. And sometimes, the information presented on one portal is simply not enough. You also have to consider whether the information is credible.

Gemini was founded in 2014 by the famous duo, the Winklevoss twins. They are famous for many reasons, one is for suing Facebook creator Mark Zuckerberg for their original idea of the social networking website. They have had an interest in bitcoin and cryptocurrencies in general and were actually involved in Bitinstant - the website that was involved in facilitating drug-deals. The duo however stated that they were only passive investors, and were not aware about the operations at length.

Gemini is based in the US, and draws the majority of its traffic from the US itself. They are fully operational in over 45 states of America, along with UK, Singapore, Canada, South Korea, Puerto Rico and Hong Kong. Their biggest market however is definitely the US. Gemini's net-worth currently stands between $1 to $10 million dollars (it is difficult to pin-point the exact number, but they're doing OK!).

The company is expanding slowly, and so far has no history of being hacked, always a positive sign. The fact that it has not been hacked does not mean it will never be hacked in future. Any malware attack on a website is almost impossible to predict. Given the fact that Gemini has not fallen victim of an attack, trust from its user base continues to grow.


The brothers focused on regulating their cryptocurrency exchange, which went in the opposite direction to other exchanges who followed the decentralised blueprint started by bitcoin. Before becoming operational, they became a fully registered and compliant enterprise, having the highest levels of banking reserves they could.

Another interesting feature about Gemini is its 'AUCTIONS' function. It should not be confused with the auctions that happen on New York Stock Exchange, but there are similarities. Auctions happen twice a day, where large volumes of crypto-assets (particularly Bitcoin and Ethereum) are traded in the short-time. This is a risky practice, as small traders might try to predict the market by studying the shift, and place orders to maintain the balance. Where big traders often win big, small traders often take the brunt of the collateral. As with all market sentiment, these auctions can increase trading emotions such as greed, fear and panic. It is advisable to be weary and not make sure you are correctly risk managed.


Some of Gemini's positives include -

  • The biggest advantage of Gemini is that it has holds most of its Bitcoin and Ethereum in offline wallets. They have only a small portion available online, which makes them low-risk, especially if the instance of an attack happens. Storing a lot of cryptocurrency offline allows them to maintain high liquidity.
  • There is no mention of a minimum amount that needs to be deposited to start trading. This feature means traders can start small before increasing size when needed.
  • The websites interface is simple to understand, and welcoming for the beginners. First timers will prefer Gemini over other complex interfaces like Bittrex or Binance Advance.
  • Gemini allows bank transfers for international account holders, when most of the exchanges prefer not to accept this function.
  • It has 2FA (two factor authentication) enabled, that adds an extra layer of security to the account.
  • The FAQ section of Gemini is full of even the smallest details and queries that a user might come up with. Their customer support is robust, active and they typically respond within a few hours. They also allow users to share their queries over email.
  • Low fees is another advantage of Gemini. Apart from charging 0.25% of standard fees from users, Gemini also has a Poloniex-like maker and taker system. If the user is placing an order to buy something, they are considered as the maker and the one who is selling is the taker. Takers will pay more than makers on Gemini. The maker fees also depends on the volume at the time, a high volume results in lower fees.


Like any exchange, Gemini has several disadvantages, as highlighted below -

  • The biggest downside of Gemini is that it allows for Ethereum and Bitcoin trading. No other cryptocurrency is available on Gemini. This restricts its variety, and prevents traders from diversifying their portfolio. Hence, Gemini is limited to be a Bitcoin Exchange and an Ethereum exchange alone.
  • For those who want to win big through margin trading, Gemini will leave you disappointed, there i s no functionality for margin trading.
  • Gemini has no mobile application for users. They are only operational on the web.
  • It is not available worldwide, only operating in a few countries, namely - USA, UK, Puerto Rico, Singapore, Canada, South Korea and Hong Kong.
  • Gemini has a history of crashes in the past. It is unable to handle huge traffic influx during peak times, and often crashes. There was an instnace where they were offline for a prolonged period and despite their repeated attempts to pacify the users, their unavailability added to the panic among users.
  • Despite offering regular operations in countries like Singapore, Hong Kong, UK, Canada and South Korea, Gemini only allows trading in USD (United States Dollars). The user cannot add any other currency. This calls for currency-conversion, and the international users have to pay unnecessary charges. This can be avoided by simply adding local currencies, which they are yet to do.

Security rating of Gemini

Gemini holds the reputation as being one of the most secure exchanges in the sector and employs a number of methods to ensure a high level of security on par with more traditional financial institutions. User accounts are backed up with two-factor authentication, which means that an additional device must be utilized in order to access the account and provides an additional layer of security.

In addition to having their US Dollar Accounts insured by the FDIC, and funds held in a New York-chartered bank. Gemini also puts all its digital assets into cold storage, while online assets are hosted on Amazon Web Services. This also provides a crucial extra level of security as Amazon Web storage utilizes security features such as multi-factor authentication, tiered-access controls, as well as dedicated hardware security modules.

Gemini’s commitment to maintaining the highest levels of security available make it a popular choice with institutional investors and high net worth individuals, as well as everyday retail investors. Customers of all types can make their transactions with confidence, regardless of their quantity.

Gemini remains one of the newer exchanges in the sector but continues to grow at a steady rate. The exchange has chosen to focus on building a fundamentally safe, secure, and efficient platform that takes care of its customers core needs.

It started out as a US Bitcoin exchange, and is slowly moving to branch out from its roots. By offering Ethereum trading pairs the exchange has opened up its options but still has a lot of room to grow in terms of trading pairs offered. Also, despite being available in a number of different jurisdictions, the US Dollar remains the only fiat currency available for both deposits and withdrawals.

Gemini can also improve its customer support options as new entrants to the world of cryptocurrency trading may require more than just email communication. Phone support and a live chat function would go a long way to improving the overall experience and help users to connect with the platform.

Review of Gemini

Gemini is undoubtedly one of the most popular cryptocurrency exchanges operating in the US, but if we talk about the global level, its reach is nowhere near to the likes of Bittrex, Binance and Bitfinex. It is secure and safe, and they have offline reserves for storing the cryptocurrency, which makes them a completely reliable wallet, but is certainly room for improvement. They must focus on enhancing their customer support, followed by adding more cryptocurrencies to their system. But a big problem to resolve is the way the website reacts to increased traffic.
