Binance Pledged to Thwart Suspicious Trading—Until It Involved a Lamborghini-Loving High Roller
Former company insiders say the firing of an internal investigator showed that the crypto exchange neglected evidence of market manipulation
When the U.S. accused Binance last year of maximizing profits over protecting users, the company promised “unceasing efforts to deliver a safe and trusted platform.”
This was put to the test soon after when an internal investigation found a top client—a firm run by a Lamborghini-loving crypto trader—was manipulating markets.
The result: Binance kept the client and fired its investigator.
The investigator and his colleagues on the company’s market-surveillance team had been hired from the traditional finance world to clean up Binance’s act. The world’s largest digital-currency exchange, born in an unregulated, freewheeling crypto culture, was under the microscope for allegedly failing to prevent the sort of manipulative trading that would get Wall Street traders thrown in jail.
Among the practices the surveillance team found: “VIP” clients—the largest on the exchange—engaged in pump-and-dump schemes and wash trading that were explicitly prohibited in Binance’s own terms of use, according to former company insiders and company documents. Binance also maintained a fleet of secret internal trading accounts that were used to trade large volumes of certain crypto tokens.
Crypto exchanges such as Binance are at the center of the digital-currency economy. Customers use them to trade one cryptocurrency for another, with Binance listing about 400 varieties, along with derivative products that allow users to bet on prices’ direction. The company says it has almost 190 million users and industry data shows it processed spot and derivatives trades worth over $4 trillion in March.
The ex-company insiders say the investigator’s dismissal in late 2023 showed that Binance—already in the crosshairs of the Securities and Exchange Commission—neglected evidence of market manipulation and prioritized generating trading fees from large clients over fixing its practices. A fresh boom this year in crypto trading has created lucrative new trading opportunities for both Binance and its high-rolling customers.
A Binance spokesperson said the company rejected any assertion that it has permitted market manipulation on the exchange and it was prioritizing the improvement of compliance functions.
“We have a robust surveillance framework that identifies and takes action against market abuse,” the spokesperson said. “We do not favor any individual user, no matter how big, over the safety of the platform.”
Decisions to remove users weren’t taken lightly and required sufficient evidence that they had breached the terms of use, the spokesperson said. A Binance executive said the company dismissed the investigator after a subsequent internal inquiry determined the claims against the client weren’t fully substantiated.
Last November, Binance pleaded guilty to violating U.S. anti-money-laundering requirements and agreed to pay a $4.3 billion fine. Its founder, Changpeng Zhao, stepped down and was sentenced last week to four months in jail on a related charge.
The exchange also faces civil charges in a SEC lawsuit. In a complaint last June, the SEC alleged Binance spun a “web of deception” in misleading U.S. investors about its risk controls to prevent manipulative trading. The SEC said Binance, along with its U.S. arm, put its own financial interests ahead of users.
The SEC declined to comment.

Expanding surveillance
Aware of the SEC investigation back in 2022, Binance began growing the market-surveillance team. It hired a dozen investigators from places such as Bank of America and hedge fund Citadel.
The surveillance team built new software tools to track market manipulation and detect wash trading, which is when traders act as buyer and seller in the same transactions to create the illusion of an active market.
The new tech opened investigators’ eyes to the potential scale of the problem, particularly among the VIP clients that Binance’s business relied on. Top traders—those trading more than $100 million a month—accounted for two-thirds of the platform’s total trading volume last year.
Investigators recommended booting out several hundred users through the first half of 2023 for violating the terms of use.
Their biggest action came last summer when they off-boarded the Tron Foundation, a blockchain company set up by crypto entrepreneur Justin Sun, a friend of Binance founder Zhao. The SEC in March 2023 charged the Tron Foundation and Sun with fraudulently manipulating the market for its own token through wash trading. Sun and the Tron Foundation, which have requested the case’s dismissal, didn’t respond to requests for comment.
Team members also observed that Binance’s own internal accounts were trading certain cryptocurrencies. They received no answer when they requested information inside Binance about who controlled them, the former company insiders said. The Commodity Futures Trading Commission, in a March 2023 complaint, had warned that Binance wasn’t disclosing to clients its own proprietary trading, which it said was run by a “quant desk” and kept “top secret.”
The Binance spokesperson said it doesn’t trade for profit or manipulate the market under any circumstances, adding its operations were “under close scrutiny.” Over the past three years, Binance has off-boarded nearly 355,000 users with a transaction volume of more than $2.5 trillion for violations, the spokesperson said.
New VIP trader
A new VIP trader began to turn heads at Binance.
DWF Labs, a trading-and-investment firm, vaulted into Binance’s top “VIP 9” designation, meaning it was making at least $4 billion in trades a month. Larger trading volumes on the exchange elevate clients’ VIP ranking, giving them discounted trading fees and access to private relationship managers.
DWF’s Russian managing partner, Andrei Grachev, bragged about his riches last October on social media. “Get into the DWF Lambo,” he tweeted with a photo of a DWF branded Lamborghini. Grachev, 36 years old, was formerly head of the Russian arm of crypto exchange HTX. He set up DWF in Singapore in 2022, corporate records show, and says he is based in Switzerland.

DWF’s role was as a so-called market maker, a type of middleman firm that simultaneously buys and sells assets, usually indifferent to whether the price of the asset goes up or down.
Market makers boost liquidity, making it easier for others to trade in and out of assets. They profit by pocketing the difference between the price they buy and sell at. In traditional finance, market makers must maintain this price neutrality under the rules of the exchange on which they operate.
Binance didn’t require market makers to sign any specific agreements that would govern their trading, allowing them largely to trade as they pleased, people familiar with their operations said. The Binance spokesperson said all users of the platform must adhere to its general terms of use that prohibit market manipulation.
Instead of price neutrality, DWF offered to use its active trading position to drive up the prices of tokens and create what it called “artificial volume” on exchanges including Binance that would lure in other traders, according to proposals it sent to potential clients in 2022.
In a report prepared that year for one customer, DWF wrote that it successfully generated artificial trading volume equal to two-thirds of the client’s token and that it was working to produce a “believable trading pattern.” Other client proposals from last year said partnering with DWF would lead to “bullish sentiment” for their tokens.
DWF and Grachev didn’t respond to requests for comment. After this article was published, DWF said on X that “allegations reported in the press are unfounded and distort the facts.” DWF operates with “the highest standards of integrity, transparency, and ethics,” it said.
Grachev told a crypto podcast last year that DWF wasn’t manipulating markets and questioned whether any trader could. “Maybe it could happen once, right? But again and again, continuously, it’s not possible,” he said.
The Binance spokesperson said they were unaware of these DWF documents. “If true, it would be very concerning to us and other participants,” the spokesperson said.
A company that DWF said it invested in was Yield Guild Games. The Swiss-registered crypto startup agreed to sell $10 million worth of its token to DWF, about a quarter of its market capitalization at the time.
The value soared fivefold last August after Binance listed a highly leveraged derivative contract tied to the YGG token. Grachev had touted YGG on X just before, claiming the listing would bring the token “sustainability and power.” Its price plummeted soon after.
The crypto industry took notice of the volatility, with two other market-making firms privately raising concerns about DWF with Binance.
One of these market makers complained about DWF’s trading to Binance’s department that handled VIP clients, which in turn connected the company with the market surveillance team. Based on this referral, the team began an investigation into DWF that September.
An investigation and a firing
Binance’s investigators found that DWF manipulated the price of YGG and at least six other tokens, and made over $300 million in wash trades in 2023, concluding these were violations of the terms of use, according to some of the former company insiders.
Following Grachev’s tweet promoting YGG, DWF sold almost five million of the tokens in two batches near the peak, triggering the collapse, they said. YGG’s co-founder, Gabby Dizon, said he wasn’t aware of the investigation’s findings.
The surveillance team submitted its report recommending DWF’s removal later in September. Over the next few days, the head of Binance’s VIP client department and her staff questioned the findings and complained to the company’s leadership.
Another Binance department, tasked with assessing employees’ compliance, launched its own investigation—this time into the market surveillance team and the evidence they had compiled on DWF.
The new inquiry determined there was insufficient evidence of DWF engaging in market abuse, the Binance executive said. The wash trades identified by the surveillance team could have been accidental so-called self-trades that may not alone amount to manipulative behavior, it found.
Binance, the executive said, also felt that the surveillance team’s head had collaborated too closely on the case with the DWF competitor who made the original complaint.
Company leaders then rejected the surveillance team’s off-boarding request.
A week after the DWF report’s submission, they fired the team’s head. Binance laid off several more investigators over the following months, which the Binance executive attributed to cost-saving measures. Others quit voluntarily. The Binance executive said the team is about the same size today.
