Manipulation Defense
Scott Armstrong tried the first cryptocurrency market manipulation case in federal court while serving as an Assistant Chief at DOJ’s Fraud Section. Drew Bradylyons served as Chief of Financial Crimes at the Eastern District of Virginia. They now defend individuals and firms facing spoofing, wash trading, and market manipulation charges in federal courts nationwide.
Scott Armstrong served for nearly a decade at the Criminal Division’s Fraud Section, including as an Assistant Chief in the Market Integrity and Major Frauds Unit. That unit is DOJ’s national leader in prosecuting fraud and manipulation in U.S. commodity and financial markets. Scott tried 16 federal jury trials at DOJ, including two market manipulation trials that are directly relevant to cryptocurrency manipulation defense. He understands how the government builds these cases because he built them. He now uses that knowledge to defend against them.
First Cryptocurrency Market Manipulation Trial in Federal Court
Scott Armstrong tried the first cryptocurrency market manipulation case in federal court while serving at DOJ’s Fraud Section. The case involved a months-long scheme to manipulate the price of a cryptocurrency token on a U.S. exchange through automated trading bots that executed approximately $7 million in wash trades and placed over $300 million in spoof trades. The government charged conspiracy to commit securities price manipulation under Title 15 and conspiracy to commit wire fraud. Scott tried the case to a jury verdict in the Southern District of Florida. The trial required presenting complex blockchain transaction data, automated trading evidence, and expert testimony on market microstructure to a federal jury. That experience gives Scott a detailed understanding of how the government presents manipulation evidence at trial and where that evidence is vulnerable to challenge.
Precious Metals Spoofing Trial
Scott Armstrong also tried a multi-week precious metals spoofing case involving senior traders at Deutsche Bank, Bank of America, and Morgan Stanley. The government alleged that the traders systematically placed large orders on the COMEX and NYMEX exchanges that they never intended to fill in order to push precious metals prices in favorable directions. The case was charged as wire fraud affecting a financial institution under 18 U.S.C. § 1343 and commodities fraud under 18 U.S.C. § 1348. The spoofing techniques at issue in that trial are the same techniques the government now targets in cryptocurrency markets. The playbook is identical: trading data, communications evidence, pattern analysis, and expert testimony. Scott knows that playbook from the inside.
Drew Bradylyons — Parallel Proceedings & Financial Crimes
Drew Bradylyons served as Chief of the Financial Crimes and Public Corruption Unit at the U.S. Attorney’s Office for the Eastern District of Virginia, one of the most active federal prosecution offices in the country. At EDVA, Drew supervised complex financial fraud cases and coordinated parallel criminal and civil enforcement matters. He understands firsthand how DOJ and federal regulatory agencies share information, align strategy, and pursue individuals across parallel proceedings. Cryptocurrency manipulation cases almost always generate parallel SEC or CFTC civil enforcement actions alongside criminal charges. Drew’s experience navigating that dynamic protects clients from making a misstep in one proceeding that becomes a liability in the other. Drew previously served at DOJ’s Fraud Section, where he supervised complex financial fraud investigations and prosecutions nationwide.
Cryptocurrency market manipulation is a federal enforcement priority. DOJ, the SEC, and the CFTC are prosecuting spoofing, wash trading, and pump-and-dump schemes in digital asset markets with increasing frequency and coordination. The charges are serious. The penalties are severe.
In April 2025, DOJ disbanded its National Cryptocurrency Enforcement Team and directed the Fraud Section’s Market Integrity and Major Frauds Unit to shift resources away from crypto enforcement. That shift did not end cryptocurrency manipulation prosecutions. It moved them. U.S. Attorney’s Offices across the country continue to bring manipulation cases under the wire fraud statute (18 U.S.C. § 1343), the securities fraud statutes (15 U.S.C. § 78j), and the Commodity Exchange Act (7 U.S.C. § 9). The April 2025 policy memo explicitly preserved DOJ’s authority to charge commodities fraud where Bitcoin and Ether are the commodities at issue.
The enforcement pipeline is active. In 2024, the FBI launched Operation Token Mirrors, an undercover operation in which agents created their own cryptocurrency token to identify market manipulation services. That operation produced indictments against multiple individuals and firms for wash trading and pump-and-dump schemes. In March 2026, the Northern District of California announced three separate indictments charging ten foreign nationals across four cryptocurrency firms with wire fraud conspiracy for coordinated wash trading schemes. Extraditions from Singapore followed.
These cases reflect a consistent enforcement posture. The government treats cryptocurrency market manipulation as wire fraud. Wire fraud carries up to 20 years in prison per count. When the fraud affects a financial institution, the maximum sentence increases to 30 years. Individuals facing these charges need defense counsel who have tried these exact cases in federal court.
Spoofing
Spoofing is the practice of placing bids or offers with the intent to cancel them before execution. The Commodity Exchange Act (7 U.S.C. § 6c(a)(5)(C)) defines spoofing as bidding or offering with the intent to cancel the bid or offer before execution. The statute does not require that the order actually be cancelled. It requires proof that the trader intended to cancel at the time the order was placed. The spoofed orders are typically large relative to the order book and are placed on one side of the market to create the appearance of buying or selling pressure. That pressure moves the best bid or offer, and the spoofer profits by executing genuine orders on the opposite side at the artificially moved price. DOJ charges spoofing in cryptocurrency markets under the wire fraud statute, the commodities fraud statute, and in some cases the anti-spoofing provision of the CEA itself.
Wash Trading
Wash trading is the execution of transactions in which there is no genuine change in beneficial ownership of the asset. The same individual or coordinated group controls both sides of the trade. The purpose is to generate artificial trading volume that misleads other market participants about the actual level of interest in a token. The Commodity Exchange Act (7 U.S.C. § 6c(a)(2)) prohibits wash sales in regulated commodity markets. In cryptocurrency markets, the government charges wash trading as wire fraud under 18 U.S.C. § 1343 on the theory that executing trades with no genuine change in ownership is an inherently deceptive act transmitted over interstate wires. The government proves wash trading through on-chain transaction analysis, exchange account records linking the buy and sell sides to the same beneficial owner, API key logs, IP address data, and communications evidence showing coordination.
Pump-and-Dump Schemes
A pump-and-dump scheme involves artificially inflating the price of a cryptocurrency through false or misleading statements, coordinated purchases, or manipulation, and then selling holdings at the inflated price. These schemes are common in smaller-capitalization tokens and newly launched coins. DOJ charges pump-and-dump schemes under the wire fraud statute, the wire fraud conspiracy statute, and, where the token qualifies as a security, the securities fraud statutes.
Bot-Based Market Manipulation
Automated trading systems, or bots, are increasingly at the center of federal manipulation prosecutions. The government targets individuals and firms that design, deploy, or commission automated systems to execute spoofing, wash trading, or layering strategies across cryptocurrency exchanges. The first cryptocurrency manipulation trial in federal court established that the individuals who build and operate manipulation bots face the same criminal exposure as the executives who commission them. Federal agents use blockchain analytics, exchange API logs, and communications evidence to connect automated trading activity to the individuals who control it.
Market Maker Manipulation
The government is targeting cryptocurrency market-making firms that cross the line from legitimate liquidity provision to market manipulation. In Operation Token Mirrors, the FBI created an undercover cryptocurrency token and used it to identify market-making firms that offered wash trading, volume inflation, and price manipulation services. The resulting indictments charged individuals at multiple firms with conspiracy to commit wire fraud and substantive wire fraud for artificially inflating token prices and volumes. This enforcement approach signals that DOJ views manipulation-for-hire services as a federal crime, regardless of how the firms characterize their services.
Securities Price Manipulation
Where a cryptocurrency token qualifies as a security under the Securities Act of 1933 and the Securities Exchange Act of 1934, the government can charge securities price manipulation under 15 U.S.C. § 78i and 15 U.S.C. § 78j. The first cryptocurrency manipulation trial in federal court resulted in charges under these provisions.
Whether a token is a security depends on the Howey test. Howey remains binding Supreme Court precedent. In March 2026, the SEC and CFTC jointly issued an interpretive release that applies Howey through a five-category token taxonomy: digital commodities, digital collectibles, digital tools, stablecoins, and digital securities. The guidance formally recognizes that investment contracts can terminate. A token sold as part of an investment contract does not necessarily carry that classification forward in secondary market trading once the issuer’s representations or promises have been fulfilled, have failed, or have otherwise terminated. This framework narrows the universe of tokens that qualify as securities and creates significant defense opportunities in manipulation cases where the government charges securities price manipulation under Title 15.
Intent is the central battleground in every market manipulation case. The government must prove that the defendant acted with the specific intent to defraud or manipulate. Trading data alone rarely establishes that element. Prosecutors rely on two additional categories of evidence to bridge the gap between trading activity and wrongful intent: cooperator testimony and contemporaneous communications.
Cooperator Testimony
Federal prosecutors build manipulation cases from the inside out. They identify co-conspirators, employees, or counterparties and flip them into cooperating witnesses. Cooperators provide testimony about the defendant’s knowledge, intent, and instructions. They explain how trading strategies were designed, who directed them, and what the participants understood about the purpose of the trades. Cooperator testimony is powerful because it puts a human voice on conduct that would otherwise appear as raw data. It is also inherently vulnerable. Cooperators testify under cooperation agreements that give them powerful incentives to testify in a way favorable to the government. Effective cross-examination of cooperators is one of the most important skills in a manipulation trial.
Employer and Institutional Communications
The government subpoenas and seizes communications from institutional platforms that log and archive messages. Bloomberg Terminal chat, internal Slack channels, Microsoft Teams messages, and recorded phone lines are primary sources. These platforms retain messages indefinitely under firm compliance and recordkeeping policies. In the precious metals spoofing cases, electronic chat messages between traders on institutional platforms provided some of the most damaging evidence at trial. Traders discussed their spoofing strategies in real time, described how to manipulate the order book, and taught colleagues how to replicate their techniques. The government treats these messages as direct evidence of intent.
Ephemeral and Encrypted Messaging
Cryptocurrency manipulation cases increasingly involve evidence from ephemeral and encrypted messaging platforms. Telegram, Discord, and Signal are widely used in the cryptocurrency industry. Federal investigators obtain this evidence through search warrants for devices and cloud accounts, through cooperating witnesses who preserved or screenshot messages, and through platform-level legal process where available. The use of disappearing messages or encrypted channels does not prevent the government from obtaining the evidence. It can also become evidence of consciousness of guilt. Prosecutors argue that the deliberate use of ephemeral messaging to discuss trading activity reflects an awareness that the activity was unlawful. The government has used this inference successfully in recent cryptocurrency fraud prosecutions.
Defense counsel must understand these evidence streams and how to challenge them. Scott Armstrong presented communications evidence at trial in both of his market manipulation cases. He knows how the government selects, sequences, and presents chat messages and cooperator testimony to construct a narrative of intent. He now uses that knowledge to deconstruct the government’s narrative and expose the weaknesses in its proof.
Challenging Intent
Market manipulation requires proof of intent to defraud or manipulate. Legitimate trading activity can produce patterns that resemble spoofing or wash trading. The defense challenges the government’s characterization of trading activity by presenting evidence of genuine economic purpose, market-making activity, and hedging strategies that explain the trading patterns the government relies on.
Trading Data Analysis
Market manipulation cases are built on trading data. The government relies on exchange records, order books, and blockchain transaction data to reconstruct trading activity and attribute it to specific individuals. The defense retains forensic trading experts to independently analyze the same data, identify weaknesses in the government’s analysis, and present alternative explanations for the trading patterns at issue.
Token Classification
Whether a cryptocurrency is a security, a commodity, or neither determines what statutes apply and what elements the government must prove. The classification question is unsettled for many digital assets. The defense challenges the government’s legal theory by contesting the token’s classification and the applicability of the statutes charged in the indictment.
Attribution and Control
The government must prove that the defendant controlled the accounts and orders at the center of the alleged manipulation. In cases involving automated trading systems, multiple exchange accounts, and cross-platform activity, attribution is often the weakest link in the government’s proof. The defense challenges the government’s evidence connecting the defendant to the trading activity, including IP address evidence, API key records, and blockchain analytics.
Cryptocurrency manipulation cases almost always involve parallel proceedings. DOJ brings criminal charges. The SEC or CFTC brings civil enforcement actions for the same conduct. Both proceedings can run simultaneously. Statements made in one proceeding can be used in the other. This creates extreme risk for individuals who do not have counsel experienced in navigating parallel tracks.
The SEC brings civil claims under Section 10(b) of the Securities Exchange Act and Rule 10b-5. The CFTC brings civil claims under the Commodity Exchange Act. Both agencies seek disgorgement, civil monetary penalties, and injunctive relief. A civil judgment for the SEC or CFTC can also create collateral estoppel issues that strengthen DOJ’s criminal case.
Drew Bradylyons served as Chief of the Financial Crimes and Public Corruption Unit at the U.S. Attorney’s Office for the Eastern District of Virginia. At EDVA, Drew coordinated parallel criminal and civil enforcement matters and understands firsthand how DOJ and federal regulatory agencies share information, align strategy, and pursue individuals across parallel proceedings. That experience is critical in cryptocurrency manipulation cases, where a misstep in one proceeding can be devastating in the other.
Scott Armstrong supervised and prosecuted complex financial fraud and market manipulation cases at DOJ’s Fraud Section alongside parallel SEC and CFTC enforcement actions. He understands how the government coordinates across agencies and how to defend against the specific risks that parallel proceedings create. Together, Scott and Drew protect clients across every front of a cryptocurrency manipulation investigation.
Scott Armstrong is one of a small number of defense attorneys in the country who has tried a cryptocurrency market manipulation case to a jury verdict in federal court. He did it as a prosecutor. He tried the first cryptocurrency market manipulation case under the federal securities laws. He also tried a multi-week precious metals spoofing case involving senior traders at three major Wall Street banks. He knows how the government builds these cases from the inside. He knows how to take them apart.
Scott served as an Assistant Chief in the Fraud Section’s Market Integrity and Major Frauds Unit, DOJ’s national leader in prosecuting fraud and manipulation in U.S. commodity and financial markets. He supervised cryptocurrency fraud investigations and prosecutions nationwide. He tried 16 federal jury trials. That trial experience is rare. It matters.

What Is Cryptocurrency Market Manipulation?
Cryptocurrency market manipulation is the use of deceptive trading practices to artificially influence the price or volume of a digital asset. The most common forms include spoofing, wash trading, pump-and-dump schemes, and the use of automated trading bots to flood exchanges with fake orders. Federal prosecutors charge cryptocurrency manipulation under the wire fraud statute, the securities fraud statutes, and the Commodity Exchange Act.
The penalties are severe. Wire fraud carries up to 20 years in prison per count. Wire fraud affecting a financial institution carries up to 30 years. Securities price manipulation conspiracy carries up to five years. These sentences can run consecutively.
What Is Spoofing in Cryptocurrency Markets?
Spoofing is bidding or offering with the intent to cancel before execution. The Commodity Exchange Act (7 U.S.C. § 6c(a)(5)(C)) defines the offense by the trader’s intent at the time the order is placed, not whether the order is ultimately cancelled. Spoofed orders are typically large relative to the order book and are placed to create artificial buying or selling pressure that moves the best bid or offer. The spoofer profits by executing genuine orders on the opposite side at the artificially moved price. DOJ charges spoofing in cryptocurrency markets under the wire fraud and commodities fraud statutes.
Scott Armstrong has tried spoofing cases in federal court. He tried a precious metals spoofing case in the Northern District of Illinois (Chicago) involving senior traders at Deutsche Bank, Bank of America, and Morgan Stanley. He also tried the first cryptocurrency manipulation case in the Southern District of Florida (Miami) involving over $300 million in spoofed trades.
What Is Wash Trading in Cryptocurrency?
Wash trading is the execution of transactions in which there is no genuine change in beneficial ownership. The same person or coordinated group controls both the buy and sell sides of the trade. The Commodity Exchange Act (7 U.S.C. § 6c(a)(2)) prohibits wash sales in regulated commodity markets. In cryptocurrency markets, the government charges wash trading as wire fraud on the theory that executing trades with no change in beneficial ownership is an inherently deceptive act transmitted over interstate wires. The government proves wash trading through on-chain transaction analysis, exchange account records linking both sides of the trade to the same beneficial owner, API key logs, IP address data, and communications evidence.
What Federal Charges Apply to Cryptocurrency Manipulation?
Cryptocurrency manipulation can be charged under multiple federal statutes. The most common charges include wire fraud under 18 U.S.C. § 1343, wire fraud conspiracy under 18 U.S.C. § 1349, commodities fraud under 18 U.S.C. § 1348, securities price manipulation under 15 U.S.C. § 78i, and securities fraud under 15 U.S.C. § 78j. Conspiracy charges under 18 U.S.C. § 371 are common where multiple individuals are involved.
The applicable statute depends on whether the cryptocurrency at issue qualifies as a security, a commodity, or neither. This classification question is often contested and can significantly affect the defense strategy.
What Is the Difference Between a Security and a Commodity in Crypto Manipulation Cases?
The distinction matters. If a cryptocurrency token is a security, the government can charge manipulation under the federal securities laws. If it is a commodity, the government relies on the Commodity Exchange Act and the wire fraud statute. The classification has historically depended on the Howey test, which asks whether the token involves an investment of money in a common enterprise with an expectation of profits derived from the efforts of others. Howey remains binding Supreme Court precedent.
In March 2026, the SEC and CFTC jointly issued an interpretive release establishing a five-category token taxonomy: digital commodities, digital collectibles, digital tools, stablecoins, and digital securities. The guidance formally recognizes that investment contracts can terminate once an issuer’s promises are fulfilled, have failed, or have otherwise ended. Under this framework, a token sold as part of an investment contract does not necessarily carry that classification forward in secondary market trading. Bitcoin, Ether, and Solana are treated as non-securities. This framework significantly narrows the tokens that qualify as securities and creates new defense arguments in manipulation cases charged under the securities laws.
Defense counsel can challenge the government’s classification of the token at issue under this evolving framework, potentially eliminating securities charges entirely and forcing the government to proceed under the wire fraud statute alone.
Has DOJ Stopped Prosecuting Cryptocurrency Manipulation?
No. In April 2025, DOJ disbanded the National Cryptocurrency Enforcement Team and redirected the Fraud Section’s Market Integrity Unit away from crypto cases. But this did not end cryptocurrency manipulation prosecutions. The April 2025 policy memo explicitly preserved the ability to charge manipulation where the conduct victimizes investors or involves commodities like Bitcoin and Ether. U.S. Attorney’s Offices continue to bring manipulation cases nationwide. The Northern District of California announced ten indictments for cryptocurrency wash trading in March 2026. The CFTC continues to bring parallel civil enforcement actions for spoofing and wash trading in crypto markets.
What Should I Do If I Am Under Investigation for Cryptocurrency Manipulation?
Retain experienced federal defense counsel immediately. Do not speak with federal agents, respond to a grand jury subpoena, or make any statements without counsel. The most consequential decisions in a manipulation investigation happen before charges are filed. Early intervention by experienced counsel can shape the trajectory of the case, protect against self-incrimination, and in some cases prevent charges from being filed at all.
Common signs that you may be under investigation include receiving a grand jury subpoena for documents or testimony, receiving a target letter from a U.S. Attorney’s Office, learning that the SEC or CFTC has issued subpoenas to your employer or exchange, being contacted by FBI agents, or learning that a colleague or counterparty is cooperating with the government. If any of these events occur, you need defense counsel who understand how the government builds cryptocurrency manipulation cases from the inside.
Can Automated Trading Bots Lead to Federal Criminal Charges?
Yes. The individuals who design, deploy, or commission automated trading systems that execute spoofing, wash trading, or other manipulative strategies face federal criminal exposure. The first cryptocurrency manipulation trial in federal court established this principle. The defendant hired an outside firm to run a bot that executed wash trades and spoofed orders. The government charged both the individual who commissioned the bot and the firm that operated it. The government uses exchange API logs, blockchain analytics, and communications evidence to connect automated trading activity to the individuals who control it.
What Defenses Are Available in a Cryptocurrency Manipulation Case?
The available defenses depend on the specific charges and facts. Common defenses include the following.
Lack of intent. The government must prove that the defendant intended to manipulate the market. Legitimate trading activity, market-making, and hedging can produce patterns that resemble manipulation. Challenging the government’s inference of intent is frequently the most effective defense.
Token classification. If the government charges securities manipulation but the token does not qualify as a security, the charge fails as a matter of law.
Attribution. The government must prove that the defendant controlled the accounts and orders at issue. This is often the weakest element in cases involving shared accounts, third-party market makers, or automated systems.
Trading data analysis. Independent expert analysis of the trading data can undermine the government’s pattern evidence and demonstrate that the trading activity had a legitimate economic purpose.
Why Does Trial Experience Matter in a Manipulation Defense?
Market manipulation cases are data-intensive, technically complex, and difficult for juries to understand. The government presents trading data, blockchain analytics, and expert testimony on market microstructure. Defending against this evidence requires counsel who have tried these cases and know how to cross-examine government experts, challenge data analysis, and present complex financial evidence to a jury in a clear and persuasive way.
Scott Armstrong has tried 16 federal jury trials, including the first cryptocurrency manipulation case in the Southern District of Florida (Miami) and a multi-week precious metals spoofing case in the Northern District of Illinois (Chicago) involving Wall Street bank traders. That level of trial experience in market manipulation cases is rare among defense attorneys.
Does Armstrong & Bradylyons Handle Cryptocurrency Manipulation Cases Nationwide and Internationally?
Yes. Armstrong & Bradylyons PLLC defends individuals and firms facing cryptocurrency market manipulation charges in federal courts across the country. The firm obtains pro hac vice admission in any federal district where a client faces charges or investigation.
Cryptocurrency manipulation cases are concentrated in the Southern District of New York, the Northern District of California, the Southern District of Florida, the District of Massachusetts, the Eastern District of Virginia, the Eastern District of New York, and the District of Columbia. Scott Armstrong and Drew Bradylyons have tried cases and handled investigations in federal courts across the country. The firm also handles cryptocurrency fraud defense and cryptocurrency litigation matters nationwide.
The firm also represents foreign nationals facing U.S. charges. Federal prosecutors increasingly pursue extradition of foreign defendants in cryptocurrency manipulation cases. Recent cases have involved arrests and extraditions from Singapore, the United Kingdom, and other countries with U.S. extradition treaties. Individuals located outside the United States who learn they are targets of a U.S. investigation should retain U.S. defense counsel immediately.
