Arthur Hayes travels with a suitcase full of stuffed animals.

The 40-year-old cryptocurrency billionaire has collected over 100 stuffed toys, each with a unique name, which he brings along to celebrate important moments in life. In his Miami apartment ------ where he once served six months of house arrest ------ visitors can see a row of toys arranged like in a child's bedroom: a yellow-green starfish, a fox, an armadillo, a giraffe, an elephant, an octopus, a snake, and a personified little bok choy.

For someone who has created the financial tools that dominate cryptocurrency trading today, this may seem a bit eccentric. But Hayes has never played by the rules.

In 2013, Bitcoin traders faced a problem that was both absurd and mathematically compelling.

Every month, their futures contracts would expire, forcing them to roll over positions repeatedly, much like playing an expensive financial version of "Sisyphus Simulator."

Rolling over contracts, paying fees, round and round, until eventually all funds trickled away through trading costs into the pockets of the exchanges.

Arthur Hayes, a derivatives trader with years of experience at Deutsche Bank and Citigroup, spent his life studying how to profit from the characteristic of "markets held together by mathematical tape." As he examined the dilemma before him, an idea that would later prove invaluable took shape in his mind:

"What if we could design a futures contract that never expires?"

This was not some philosophical speculation ------ Hayes was not entangled in existential questions about the nature of time.

He was pondering: what if it were possible to create a futures contract that never expires, completely ending the monthly cycle of extracting fees that was gradually driving global Bitcoin traders to bankruptcy?

The answer made him a cryptocurrency giant, creating the financial tool that now supports most cryptocurrency trading, only to face federal criminal charges for creating it without prior approval from relevant authorities.

This is a story about traditional financial logic breaking into the "wild markets" ------ markets built by a group of programmers who view regulation as "suggestions." What sparks fly when rigorous financial logic collides with the spontaneous world of code?

Hayes grew up in Detroit in the 1980s, where both of his parents worked for General Motors, understanding that education was the only reliable way to escape the cyclical ups and downs of the auto industry. To enable him to attend Nichols School, they moved to Buffalo. It was a preparatory school where rich kids learned Latin while poor kids learned to network with the wealthy.

He graduated second in his class and joined the school’s lacrosse team. After transferring between the University of Hong Kong and Wharton, he earned a degree in economics and finance in 2008, a perfect time to witness the collapse of the global financial system in real-time.

Hayes did not stay in New York to participate in the profound reflections on whether Wall Street was terminally ill after the financial crisis; instead, he moved to Hong Kong. This move proved to be highly prescient ------ in Hong Kong, you could trade complex derivatives without anyone sharply questioning the systemic risks involved.

Learning the "Language" of Derivatives

As a broke intern, Hayes turned food delivery into a business, charging a markup on each order from his colleagues, earning a few hundred dollars a week. During Wharton’s recruiting season, he took recruiters to nightclubs in Philadelphia, leaving a strong impression. His work attire became legendary: on one "Casual Friday," he wore a tight pink polo shirt, acid-washed jeans, and bright yellow sneakers, prompting a department head to exclaim, "Who the hell is that guy?" This incident led the company to cancel "Casual Fridays."

In 2008, Deutsche Bank's Hong Kong branch hired Hayes as a stock derivatives trader. It was here that he dove into the complex mathematical world of derivatives ------ the value of these financial instruments comes precisely from the underlying assets behind them.

He specialized in Delta-one trading and ETFs, which are akin to "pipeline engineering" in finance; not glamorous, but essential. And once you grasp the logic of how the pipelines connect, you can profit from them.

(Note: Delta-one trading is a financial trading method that tracks the price movements of underlying assets through products that have a 1:1 relationship with the asset price, such as ETFs and futures.)

After three years of honing his skills to arbitrage price differences that last only about 17 seconds, he jumped to Citigroup in 2011. But by 2013, with tighter banking regulations, the good times came to an abrupt halt. Hayes was fired, but this led him to encounter the Bitcoin market just as it desperately needed knowledgeable "financial plumbers."

In 2013, Bitcoin exchanges were built by people who understood blockchain protocol coding ------ these individuals could code but had never heard of "margin requirements." To Hayes, this market was: operating 24/7, with no circuit breakers, no central oversight, and no complex risk management. It was either the future of finance or a clever design that would quickly drain people's money ------ and in his view, both possibilities could coexist.

Despite the rudimentary infrastructure, the underlying mechanisms captivated him. This was clearly a market that urgently needed the financial engineering skills he had learned from traditional finance.

Building BitMEX

He teamed up with Ben Delo and Samuel Reed ------ the former was a mathematician capable of building trading engines, while the latter truly understood the operational logic of cryptocurrencies. In January 2014, the three began developing BitMEX (Bitcoin Mercantile Exchange), claiming they would create "the premier peer-to-peer trading platform," competing against those mostly poorly functioning, barely usable exchanges.

The skills of the three founders complemented each other perfectly: Hayes understood market structure and derivatives, Delo could build complex trading engines, and Reed was well-versed in cryptocurrency technology.

BitMEX launched real-time trading on November 24, 2014, focusing on Bitcoin derivatives. This timing was the result of months of careful development and stress testing. At launch, the founding team was actually scattered around the globe ------ Hayes and Delo in Hong Kong, while Reed participated remotely from Croatia on his honeymoon.

Early products included leveraged Bitcoin contracts and Quanto futures, allowing traders to express their views on Bitcoin prices without actually holding the underlying asset. These complex tools required a deep understanding of margin, clearing mechanisms, and cross-currency hedging ------ which was precisely Hayes's team's strength.

(Note: Quanto futures are derivative contracts where the underlying asset is priced in one currency but settled in another currency at a pre-agreed exchange rate, thus eliminating the risk of exchange rate fluctuations at settlement.)

But their ambitions went far beyond that.

On May 13, 2016, BitMEX launched an unprecedented innovation: the XBTUSD perpetual contract. This was a futures-like tool that never expired, anchoring the contract price to the Bitcoin spot price through a funding payment mechanism between long and short positions. The contract offered up to 100x leverage and settled in Bitcoin.

Traditional futures expire monthly, forcing traders into an absurd cycle of "rollover - pay." Hayes drew inspiration from the funding mechanisms of the forex market, injecting new logic into Bitcoin futures: contracts would not expire but would self-correct through mutual payments between longs and shorts: when the contract price was above the spot price, longs paid shorts; when below, shorts paid longs.

This design eliminated expiration dates, reduced trading costs, and was practical enough for all cryptocurrency exchanges to immediately emulate. Today, perpetual contracts account for a significant portion of global cryptocurrency trading volume. Hayes essentially "solved" the time problem, at least in the realm of derivatives contracts.

Explosive Growth and Regulatory Scrutiny

BitMEX's XBTUSD contract quickly became the most liquid Bitcoin derivatives market globally. Its mature risk management, professional-grade tools, and high leverage attracted both traditional financial traders and native cryptocurrency players.

By 2018, BitMEX's daily notional trading volume had surpassed $1 billion. The exchange moved into the 45th floor of the Cheung Kong Center in Hong Kong ------ one of the city's most expensive office buildings. In August of the same year, when BitMEX's servers went down for planned maintenance, the price of Bitcoin surged 4%, adding $10 billion in market value to the entire cryptocurrency market.

BitMEX nominally prohibited U.S. customers from participating, but critics claimed these restrictions were largely ineffective. Its influence on Bitcoin pricing caught the attention of scholars, regulators, and politicians newly engaging with the cryptocurrency market.

In July 2019, economist Nouriel Roubini published a report accusing BitMEX of "systemic illegality," allowing excessive risk-taking and potentially profiting from customer liquidations. These accusations triggered regulatory investigations and congressional hearings on the structure of the cryptocurrency market.

By the end of 2019, the daily trading volume of Bitcoin derivatives had reached $5-10 billion, more than ten times that of spot trading. BitMEX held a significant share of this market, making Hayes and his partners central figures in the global cryptocurrency landscape.

On October 1, 2020, the long-anticipated federal lawsuit was filed: the CFTC initiated a civil complaint, and the Department of Justice (DOJ) announced criminal charges, stating that BitMEX operated as an unregistered futures broker while servicing U.S. customers and ignored anti-money laundering requirements. Prosecutors pointed out that Hayes and his partners deliberately evaded compliance while earning hundreds of millions in profits.

Hayes resigned as CEO that day. Reed was arrested in Massachusetts, while Hayes and Delo were listed as "fugitives" ------ a term used by the DOJ meaning "we know where you are, we just haven't moved to arrest you yet."

This legal battle lasted over two years, during which Hayes unexpectedly discovered his talent for writing market and monetary policy analyses. His "Crypto Trader Digest" column became essential reading for anyone trying to understand the connections between macroeconomics, Federal Reserve policies, and cryptocurrency prices. The analytical framework he built explained why central bank decisions would ultimately drive people toward Bitcoin.

In August 2021, BitMEX agreed to pay $100 million to settle civil charges. On February 24, 2022, Hayes pleaded guilty to charges of "willfully failing to establish an anti-money laundering program." On May 20 of the same year, he was sentenced to six months of house arrest, two years of probation, and a $10 million fine.

During the litigation, Hayes gradually became one of the most insightful commentators in the cryptocurrency space. His analyses of Federal Reserve policies and Bitcoin price dynamics reshaped traders' and institutions' perceptions of cryptocurrency as a macro asset. The concept of "NakaDollar" he proposed was highly forward-looking: creating synthetic dollars through a combination of Bitcoin longs and perpetual contract shorts, obtaining dollar exposure without traditional banking.

Hayes also candidly emphasized the value of Bitcoin as a hedge against currency devaluation: "In the realm of fund transfers, we are transitioning from an analog society to a digital one, which will bring about tremendous disruption. I see opportunities to create companies using Bitcoin and cryptocurrencies that can benefit from this chaotic transformation."

On March 27, 2025, President Trump pardoned Hayes and the co-founders of BitMEX, closing this chapter of legal troubles. By this time, Hayes had already embarked on a new venture outside of BitMEX, serving as the Chief Investment Officer of the family office fund Maelstrom, investing in areas including venture capital, liquidity trading strategies, and cryptocurrency infrastructure.

The fund supports Bitcoin development by providing grants ranging from $50,000 to $150,000 to developers, as stated on the Maelstrom website: "Bitcoin is the cornerstone asset of the cryptocurrency space; unlike other projects, it has never financed technological development through token issuance." This reflects Hayes's emphasis on sustainable funding support for open-source development.

Recent Market Trends

Hayes's current investment strategy mirrors his macro vision. In August 2025, he made headlines for purchasing over $15 million in cryptocurrency within five days, focusing on Ethereum and DeFi tokens rather than Bitcoin. This included 1,750 Ethereum (worth $7.43 million) and a significant amount of HYPE, ENA, and LDO tokens. This allocation stemmed from his judgment that certain altcoins would benefit from the current market environment, namely institutional favor for Ethereum, rising stablecoin adoption, and various protocols generating revenue by filling market gaps.

Hayes is also one of the most outspoken supporters of Ethena (ENA). This synthetic dollar protocol is based on the derivative concepts he pioneered at BitMEX. In August 2025, he purchased 3.1 million ENA tokens (worth $2.48 million), becoming one of the largest individual holders of the project. To him, Ethena represents the evolution of the "NakaDollar" concept: creating dollar-pegged assets using derivatives without relying on the traditional banking system. This investment is his bet on a new generation of projects: they are redefining the operation of synthetic assets using perpetual swaps and funding mechanisms.

Earlier that month, he sold $8.32 million worth of Ethereum at nearly $3,500 due to concerns about the macro economy. However, when Ethereum rebounded above $4,150, he bought back all his positions and candidly stated on social media: "I had to buy it all back. I swear, I won't take profits again."

The core of Hayes's current macro argument is his belief that the Federal Reserve will inevitably begin printing money. He points out that structural issues such as pressure in the real estate market, demographic changes, and capital outflows will force policymakers to inject about $9 trillion into the financial system. "If we don't print money, the system will collapse." He particularly emphasizes the debt burdens of institutions like Fannie Mae and Freddie Mac.

If this scenario comes to pass, Hayes predicts that Bitcoin could reach $250,000 by the end of the year, as investors seek alternatives to fiat currency devaluation. Based on the unsustainability of the current monetary system and Bitcoin being the most viable store of value alternative, he believes Bitcoin could reach $1 million by 2028.

Perpetual contracts fundamentally changed cryptocurrency trading, eliminating many frictions present in early derivatives markets. By 2025, even mainstream platforms like Robinhood and Coinbase were launching their own perpetual products, while new exchanges like Hyperliquid built complete businesses around Hayes's original innovations.

The regulatory framework born from the BitMEX case also shaped industry standards: comprehensive anti-money laundering programs, customer verification, and regulatory registration became prerequisites for any exchange serving the global market.

At 40, Hayes occupies a unique position in the cryptocurrency ecosystem. He has experienced traditional finance before Bitcoin's birth, possesses the ability to build the infrastructure that defines cryptocurrency trading, and has endured both explosive success and severe legal consequences.

His story proves that sustainable success in the cryptocurrency space requires understanding the balance between technology and regulation, innovation and compliance. The success of perpetual contracts is not only due to their clever technology but also because they solved real problems for traders. At least until the regulatory framework catches up with the pace of innovation.

"When we built all this back then, we didn't need anyone's permission. Which industry can let three ordinary people create an exchange with daily trading volumes in the billions?" Hayes reflects on his experience building BitMEX with a sense of wonder.

This statement captures the opportunities and responsibilities of building financial infrastructure in a rapidly evolving regulatory environment.

Today, Hayes continues to analyze the market and make heavy bets based on macro judgments. His influence has long surpassed individual trades or investments. Through articles, investments, and ongoing participation in the cryptocurrency market, he remains one of the most insightful voices in an industry often characterized by hype over analysis.
