BitMEX is a peer-to-peer cryptocurrency trading platform based in the island of Mahé.[1]


BitMEX offers bitcoin derivitives trading, including margin trading and liquidation services.[2] It is one of the largest cryptocurrency trading platforms in the world, ranking third by traded volume according to reported trading volumes by CoinMarketCap.[3]

In August 2018, BitMEX moved into the 45th floor of the Cheung Kong Center in Hong Kong, one of the most expensive offices in the world.[4] Around the same time as the move-in, BitMEX servers went down for scheduled maintenance. Almost immediately, bitcoin prices increased by 4%. This ended up adding $10 billion to the market cap of all cryptocurrency assets.[5][6][7]

In a February 2019 blog post, BitMEX reported that it had traded a $1 trillion notional worth of cryptocurrency contracts in 2018. In the same blog post BitMEX described the functioning of its insurance fund, which supports their leveraged contracts.[8] In August 2019, The Block Crypto reported that The BitMEX insurance fund had increased by about 50% since January 1, 2019.[9]

In May 2019, BitMEX wrote on its blog that, although the company offers a maximum of 100x leverage on its derivatives trading, the majority of traders do not trade at maximum leverage. BitMEX CEO Arthur Hayes said that this reflected "quite responsible" behavior on the part of BitMEX's customers. According to BitMEX's data, the average leverage used by BitMEX traders is 29x on long positions and 26x on short positions.[10]

In July 2019 Nouriel Roubini released a report in which he suggested that BitMEX may be involved in "systemic illegality." He said that BitMEX allows its users to take on too much risk. He also said that it's possible that liquidation of user accounts may contribute significantly to the exchange's income, and that BitMEX may trade against its clients, citing a widely-circulated post on Medium from 2018. Though representatives from BitMEX denied these claims, Roubini wrote that Hayes, BitMEX, and anybody else facilitating cryptocurrency trading from overseas regulatory "safe havens" should be investigated.[11][12]

Over the first half of 2019, BitMEX's Insurance Fund increased by over 50 percent, meaning that the exchange held nearly 0.15 percent of the world's total supply of bitcoins.[13]

Against a backdrop of rumors that the CFTC was investigating the exchange and less than a year into the job, COO Angelina Kwan left her position. Kwan had previously been a senior regulatory executive at the Stock Exchange of Hong Kong.[14]

By late 2019, bitcoin derivatives accounted for $5-10 billion worth of trade volume per day - more than 10 times the volume created by bitcoin spot trading. BitMEX accounted for the majority of it, trading an average of $1.82 billion bitcoin per day.[15]


In a mass email distribution to its users, BitMEX inadvertently published the email addresses of up to 30,000 of its users. According to press sources, the company distributed the email through "cc:" functionality instead of "bcc:", which blinds all other recipients.[16] The company notified its users of the breach by email.[17]

Geographical Access Restrictions

Also in July 2019, Bloomberg reported that BitMEX was under investigation by the CFTC, the federal regulatory agency that oversees commodity and futures marketplaces in the U.S. for permitting U.S residents to trade on its platform without BitMEX being registered as a designated contract market.[18] On July 20th, numerous Twitter users began tweeting that BitMEX's trading volume had fallen by 33%.[19]

On August 19 BitMEX announced it would also block persons in Seychelles, Bermuda and Hong Kong, all locations where HDR Global Trading, BitMEX's parent, has offices.[20]

Products and Services

Perpetual Contracts

BitMEX offers what it calls "perpetual" contracts, which are similar to futures contracts. The difference between perpetual contracts and futures is that, unlike futures, perpetual contracts do not have expiry dates, allowing the trader to hold on to a position until the trader chooses to end it.


BitMEX also offers options that it calls "BitMEX DOWN" and "BitMEX UP" contracts. Buying "BitMEX DOWN" contracts lets holders participate in a market decline, and Buying "BitMEX UP" contracts lets investors participate in a market rally. In both cases, an investor's potential loss is limited to the investor's initial payment, taking the form of a premium paid on a specified trade date in bitcoin (BTC). Gains are paid out in BTC. Investors cannot these contracts.[21]


CEO and Founder Arthur Hayes revealed in a podcast in mid April 2019 that BitMEX was developing an options trading platform that would be launched a year to a year-and-a-half later. Hayes said that BitMEX was working with university professors on the design.[22]

Trading Technologies

In April 2019, the Chicago-based trading software developer Trading Technologies (TT) announced a new partnership with HDR Global Trading, owner of BitMEX. TT said in a blog post that through this partnership, TT's users eligible to trade at BitMEX will have full access to BitMEX's products, including its XBT/USD Perpetual Swap. Arthur Hayes, the CEO of BitMEX, said that this new partnership will "advance our mutual vision to unlock access to cutting-edge cryptocurrency products."[23][24]


BitMEX was founded in 2014 by Hayes, a former Citigroup equities trader who wanted to create a bitcoin derivatives exchange. Hayes was reportedly bored by the traditional financial services industry, and became interested in cryptocurrency asset trading, which he regards as similar to traditional asset trading in the '80s and '90s.[25][26]
