Sophisticated actors are taking from amateur investors in bitcoin derivatives trading, according to Carnegie Mellon researchers using data from BitMEX.
As the market for crypto derivatives booms, researchers at the top U.S. university Carnegie Mellon have warned in a new study that sharp price swings and liquidations could disproportionately impact smaller traders.
The new study by Pittsburgh, Pennsylvania-based Carnegie Mellon University’s CyLab, published April 19, found that trading volume in cryptocurrency derivatives exceeds that of the underlying spot markets.
“Sophisticated actors are taking from amateur investors,” Kyle Crichton, a researcher at the lab who co-authored the report, said in an interview. “Wealth centralization is taking place and there are a few big players.”
Liquidation events occur when traders cannot fulfill margin requirements for holding crypto derivative positions and often exacerbate price moves. In April, bitcoin (BTC, +6.05%) futures saw a record $10 billion worth of liquidations in one day after data showed leveraged traders were excessively skewed bullish. The liquidation coincided with a near 15% drop in BTC from an all-time high around $65,000.“When markets are trending up, everybody makes money, but during a wipeout, a few big actors take everything and the little guys are taken out,” Crichton said.Traders who take on smaller contract sizes are typically more long-biased, or betting on bullish price movements, according to the study. The short side of the trade typically consists of hedgers who own spot bitcoin or cryptocurrency miners who want to manage revenue volatility by locking in prices for a specific delivery date in the future.
That means traders who have short positions in the derivatives market are more likely to be price-neutral in terms of their overall positions, making the BTC futures market more of a speculative net-long play, according to Crichton.“This is why there is a distinct asymmetry with long positions that are more leveraged with small position sizes,” Crichton said.The researchers analyzed trading activity on BitMEX, a derivatives exchange launched in 2014 that trades over $3 billion worth of volume per day on average and allows users to go long or short bitcoin with leverage of up to 100 times, often shorthanded as “100x,” according to the report.“We focused on BitMEX because they were the only player back in 2014 and remained relevant for a long period of time,” said Crichton.In October 2020, the U.S. Commodity Futures Trading Commission (CFTC) charged BitMEX with executing futures transactions on an unregistered board along with other counts “in an attempt to evade U.S. regulations,” according to the CFTC legal filing.
When contacted by CoinDesk for comment, a spokesperson for 100x Group, the holding structure for BitMEX, pointed to a statement that the exchange had provided to the researchers in advance of publication, in which exchange executives took issue with some parts of the draft.
“The paper contains various inaccurate and/or misleading statements that do not properly reflect the platform’s structure and operations,” according to that November 2020 statement, which was included in the final report.
In an email, the spokesperson wrote that “whilst higher leverage is available, we’ve historically seen the majority of traders opt to use lower leverage, with the notional weighted average leverage being under 10x.”

CyLab also published a companion website with real-time analytics of BitMEX data and says it encourages collaboration across the crypto research community.“Crypto has gained a lot more attraction in the academic world in terms of being a more legitimized thing,” Crichton said.
