Gemini Bitcoin Exchange Review

Aiming to provide a sturdy and reliable bridge to the future of money – according to its own slogan – Gemini ( is a New York-based crypto currency exchange launched in October 2015, by the Winklevoss twins of Winklevoss Capital Management LLC. The company behind the exchange is Gemini Trust Company LLC, and Tyler Winklevoss is its CEO. Having been involved in various Bitcoin-related investments for years, the Winklevoss twins saw it fit to err on the side of caution this time, pushing their startup through a series of regulatory hoops, earning a license as a New York State Limited Liability Trust instead of operating under Bitlicence. This way, the exchange can serve corporate as well as retail clients.

Gemini currently has offices in most of the US states, in Canada, as well as in the UK, in London. The current address of the Gemini Trust Company headquarters is 600 Third Avenue, 2nd Floor, New York, NY 10016. They can be contacted via toll-free phone at +1(866)240-5113.


Open 24/7, the exchange features three currency-pairs: BTC/USD, ETH/USD and BTC/ETH.

Trading Platforms

Gemini runs on three distinct order-matching engines, one for each of the above said currency pairs. Every trade executed through the Gemini marketplace is reported both to the public and the customer through the market data API. Gemini is a full-reserve exchange meaning that all trades hosted by its platforms are pre-funded. Gemini also features public and private REST APIs for which full documentation is available at Amazon Web Services acts as the host of the hot wallet of the operation, while cold-storage tasks are fulfilled by state-of-the-art systems.

Account Types

All Gemini Customers trade from pre-funded accounts. Personal accounts are the default ones. Institutional traders have to go through a separate registration process.

Commissions and Fees

The current deposit and withdrawal fees are 0, and there is an 0.25% trading fee taken of both sides of a trade. There’s a dynamic fee schedule across all three order matching engines. Liquidity-making trades can generate rebates of up to 0.15%, while liquidity-taking trades incur a fee of 0.15%.


Gemini Trust Company LLC operates in full compliance with the New York Banking Law and its activity is regulated by the New York State Department of Financial Services. As a fiduciary, it can work with retail- as well as institutional customers. The company has an account with FinCEN too, though it isn’t required by law to register with the authority.

Customer Support

Customer support is apparently one of the more maligned aspects of the operation. Gemini support can only be reached through a Zendesk-powered email form. The Help Center provides an FAQ section too.

Payment Methods

Gemini accepts deposits and honors withdrawals through Bitcoin, Ether, Wire Transfer and ACH. In all cases, no fees are associated with the operations.


With well-known celebrity investors in its background, Gemini is a genuine US-based and fully regulated crypto currency exchange, that has thus far done its work without significant hiccups. Admittedly however we could not find a lot of testimonials and reviews from Gemini customers. This most likely indicates that Gemini a trustworthy bitcoin exchange, otherwise we would surely find some bad reviews.

    I have invested $750.00 Than I sold $306.00 , never deposited in to my Bank Account. the froze my account. I have e mailed them did what the ask to send selfie Picture ,Drivers License and a note . Still no Money Back Yes its a scam

    Customer service is nonexistent! Once your account is approved buying is pretty easy – BUT when you try to move funds – GOOD LUCK!

    Customer support is only via email and then after 4 or 5 days they will reply with a one line question – like what is your phone number. Then no response for another 2 or three days.

    They claim to be the most TRUSTWORTHY crypto exchange. I would argue they are one of the worst.

    I have read all the above reviews. However, most reviews are over a year ago or so. I have made a few buy, sell and send orders and all went flawlessly. I moved to Gemini because coinbase has shut my account down, a long story like so many others and with several calls and approaching 9 months lost money when profiting, etc.

    Wow, my experience with Gemini is the opposite of all the reviews so far. They seem to be growing too fast – like everyone in year end 2017 – but once I got verified and bank approved for remittances and withdrawals – everything is as smooth as butter. I send out payments – they don’t get held up. I buy and sell – quick and smooth. I make deposits and withdrawals – no problems whatsoever. This is my favorite exchange by a LANDSLIDE. Not a paid shill, I really like this exchange. Probably people posting here have a prediliction against Gemini, but they seem to be handling lots of volume (as judged by their order book which is public).

    My experience has been exactly the same as the above experience. Don’t bother! Bummer…

  6. B.C.

    Still horrible customer service. You can’t get to a real person. After jumping through their hoops to get verified, my account was ‘frozen. finally got it unfroze, only to have subsequent deposits returned and my account frozen again. Waiting again for my account to be straightened out. In the meantime, I’ve lost a lot of money being unable to trade.

    They have the worst customer service i have ever experienced. I don’t understand the point of owning/ running a business if you don’t respond to customers applying for a new account.

  8. Philip

    reluctant to give them my SS number, But they also do not recognize my local bank here in Montana ( that’s now new, but a bit scary, Only option is a wire transfer which requires a set-up including my SS number. I’ll defer using them until it get a better review or two

  9. Cole

    This is the worst customer service support I have ever experienced. I have been trying to jump through all the hoops they want you to go through just to open up an account. Wired money twice and both were rejected by Gemini. No phone support and customer support is useless! They have a F rating at the BBB and now I know why. The Winklevoss twins should be ashamed of their scam company they own.

  10. Scott

    I have wired them money and they will not apply it to my account. What is worse is that they will not return it either. It has been almost 2 weeks. I tried to call customer service but that phone number it only prompts you to email support. The email support does not answer, at least not with the truth anyway. I did get one response that they were sending the money back that day, but they never did. That message was on Friday, it is now Tuesday and they have not sent anything back. I have reported the incident to the New York State Department of Financial Services, but they have not responded.

    The scary thing is that I have found several other similar stories online.

SOMEONE NEEDS TO COME OUT WITH A HUGE ARTICLE BASHING GEMINI. THOSE WINKLEVOSS TWINS JUST GET EASY MONEY FROM ANYONE. FUCKING AHOULD HAVE NEVER TRIED INVESTING IN BITCOIN I FEEL LIKE ALL THE WEBSITES OUT THERE HAVE SCAMS.

  11. Edita Dun

    The worst customer service ever! No email confirmation, No one ever answers the phone and no response to emails! I WILL NEVER recommend this business for bitcoin trading!

  12. Kelly Mitchell

    Gemini is crap, like most exchanges. Order types? No stop-loss, no trails, no hidden orders (maybe for whales at extra cost). You can’t modify standing orders, you have to cancel and re-place them.
    Once the exchanges get past this 1980’s structure then professionals will trade and we’ll have real liquidity and functionality. Until then, it’s light trading and mainly hodl for me.
