Guide to Crypto and Blockchain: Crypto and Blockchain Enforcement
Targeted in a Crypto Enforcement Action?
If federal agents are investigating you, you may be in real legal danger.
The government is going after individuals and companies tied to cryptocurrency — and they’re moving fast. Whether it’s a subpoena from the SEC, a search warrant from the DOJ, or a civil complaint from the CFTC, you need experienced defense counsel who understands both crypto and federal enforcement.
At Dynamis LLP, we defend clients across the country in complex crypto-related investigations and prosecutions. We're not generalists. We're former DOJ prosecutors who know how these agencies work, what mistakes they make, and how to shut down weak cases before they spiral into indictments.
What Crypto Cases Look Like Right Now
Regulators are casting wide nets. Even legitimate crypto activity can trigger scrutiny if it looks unfamiliar or threatens traditional financial systems.
Here are the charges we see most:
Unregistered Securities Offerings — If you launched a token, an NFT, or ran a staking or lending program, the SEC might say you sold securities illegally.
Wire Fraud — Misstatements to investors, whitepapers that overpromised, or public statements that moved markets can all draw DOJ attention.
Market Manipulation — Price pumps, token coordination groups, or high-volume trading patterns may trigger allegations of spoofing or wash trading.
Money Laundering — Moving assets through mixers, exchanges without KYC, or foreign wallets can be enough to trigger charges.
Conspiracy or RICO — The DOJ uses these to rope in multiple players, even if their roles were minor or indirect.
You don’t need to be guilty to be charged. You just need to be misunderstood—or convenient. A criminal or regulatory investigation is expensive and will damage your reputation. Experienced counsel is needed.
The Agencies You're Dealing With
SEC – Civil Enforcement
The Securities and Exchange Commission leads most crypto enforcement actions. They file civil lawsuits for alleged violations of federal securities laws—particularly unregistered securities offerings.
Expect:
Subpoenas demanding documents and communications
Wells Notices warning that charges are coming
Freezes on wallets or accounts
The SEC isn’t just after companies. It targets founders, developers, and marketers personally.
DOJ – Criminal Prosecution
The Department of Justice handles criminal investigations. If you're under DOJ scrutiny, jail time is on the table. They pursue:
Wire fraud
Securities fraud
Money laundering
Obstruction
You may face:
Search warrants
Grand jury subpoenas
Target letters
DOJ prosecutors collaborate with FBI agents, IRS-CI, and even international authorities. If you wait too long, they’ll lock in their narrative—and you’ll be playing defense from behind.
CFTC – Commodities Oversight
The CFTC goes after crypto products they view as commodities, such as Bitcoin and Ethereum. They bring civil actions for fraud and unregistered trading platforms. If you ran a DeFi app, DEX, or margin product, the CFTC may knock.
State Attorneys General
Don’t forget state enforcers. The NYAG, Florida AG, and Massachusetts AG have all pursued high-profile crypto cases. They often team up with federal agencies.
