How to File a Criminal Complaint for Crypto Fraud

1. Legal Basis — What Crimes Apply?

Cryptocurrency fraud can fall under multiple federal and state criminal statutes. The specific charges depend on the nature of the scam, but several federal laws are commonly applied.

Wire Fraud (18 U.S.C. Section 1343)

The primary federal statute used to prosecute crypto scams. Wire fraud covers any scheme to defraud using electronic communications, which encompasses virtually all internet-based cryptocurrency scams. Elements include a scheme to defraud, use of wire communications (internet, email, messaging), and intent to deprive the victim of money or property. Penalties include up to 20 years in federal prison per count, with enhanced penalties of up to 30 years if the fraud affects a financial institution.

Computer Fraud (18 U.S.C. Section 1030 — CFAA)

Relevant when the fraud involved unauthorized access to computer systems, such as phishing attacks that steal exchange login credentials, malware that replaces wallet addresses in the clipboard, SIM-swapping to bypass two-factor authentication, or exploitation of smart contract vulnerabilities. The CFAA carries penalties of up to 10 years for a first offense and up to 20 years for repeat offenders.

Additional Applicable Laws

Money laundering (18 U.S.C. Section 1956): applies when stolen crypto is moved to conceal its origin, carrying up to 20 years. Securities fraud (15 U.S.C. Section 78j): relevant for investment scams, ICO fraud, and unregistered securities offerings, carrying up to 20 years. Commodity fraud: the CFTC has jurisdiction over Bitcoin as a commodity, enabling enforcement for futures and derivatives scams. State-level fraud statutes in most states also apply and can be pursued in parallel with federal charges.

2. FBI Internet Crime Complaint Center (IC3)

The FBI's IC3 at ic3.gov is the primary federal portal for reporting internet-enabled financial crime, including all forms of cryptocurrency fraud. IC3 is the single most important place to file a complaint because it feeds directly into the FBI's investigative pipeline and shares data with over 100 law enforcement agencies worldwide.

What to Include in Your IC3 Filing

Your IC3 complaint should include: a clear chronological narrative of how the scam unfolded, all cryptocurrency wallet addresses involved, all transaction hashes (TXIDs) of your payments, the total loss amount in both cryptocurrency and USD, screenshots of all communications with the scammer (email, chat, social media), the URL and screenshots of any scam website, and your blockchain analysis PDF. The more detailed your submission, the higher the likelihood of investigation.

IC3 Recovery Asset Team (RAT)

IC3 operates the Recovery Asset Team, which specializes in time-sensitive cases where funds may still be recoverable. RAT coordinates with domestic and international financial institutions to freeze funds before they are liquidated. If your loss is recent (within 72 hours) and involved a wire transfer or exchange deposit, clearly mark the urgency in your IC3 filing. RAT has successfully frozen and recovered funds in hundreds of cases, but speed is critical.

3. Additional Federal Agencies

Federal Trade Commission (FTC)

File a report at reportfraud.ftc.gov. The FTC tracks fraud trends and uses consumer reports to bring enforcement actions against deceptive business practices. Your report feeds into the Consumer Sentinel Network, a database accessed by over 2,800 law enforcement agencies across the US and internationally. While the FTC does not resolve individual cases, aggregated reports help them identify major scam operations and take action.

Securities and Exchange Commission (SEC)

If the scam involved an investment scheme, token sale, ICO, or any product marketed as a security, file a complaint with the SEC at sec.gov/tcr. The SEC's Crypto Assets and Cyber Unit actively pursues enforcement actions against fraudulent token offerings, unregistered exchanges, and investment scams. The SEC's whistleblower program can provide financial awards of 10-30% of sanctions exceeding $1 million resulting from information you provide.

Commodity Futures Trading Commission (CFTC)

The CFTC classifies Bitcoin and other cryptocurrencies as commodities. If the scam involved futures, options, derivatives, or leveraged trading, file at cftc.gov/complaint. The CFTC has brought numerous enforcement actions against fraudulent crypto trading platforms and Ponzi schemes.

State Attorney General

File a consumer complaint with your state's Attorney General office. Many states have dedicated consumer protection divisions that investigate fraud. The National Association of Attorneys General maintains a directory at naag.org. State investigations can sometimes move faster than federal ones and may result in injunctions that stop ongoing scam operations within your state.

4. Local Law Enforcement

Always file a report with your local police department, regardless of which federal or international agencies you report to. The local police report generates an official case number that you will need for bank chargebacks, exchange compliance requests, insurance claims, and civil litigation. While many local police departments do not have specialized cryptocurrency units, the report creates an official record in law enforcement databases.

Preparing for Your Report

Bring a printed summary of the incident along with a USB drive containing digital evidence. Include a one-page chronological summary, all wallet addresses and transaction IDs, screenshots of communications, your blockchain analysis PDF, and receipts or bank statements showing the funds you sent. Having everything organized and clearly labelled makes it significantly easier for officers to process the report accurately and completely.

5. International Reporting

Most cryptocurrency scam operations are internationally organized. Filing with international agencies increases the chances of catching cross-border criminal networks.

United Kingdom: Action Fraud

Action Fraud (actionfraud.police.uk) is the UK's national fraud and cyber crime reporting centre, operated by the City of London Police. Reports are assessed by the National Fraud Intelligence Bureau (NFIB). Relevant if the scam operated from or through the UK, or if funds passed through UK-based exchanges.

Europe: Europol and National Police

Europol's European Cybercrime Centre (EC3) coordinates cross-border cybercrime investigations within the EU. While you cannot file directly with Europol, reports to national police forces are shared through the European information exchange framework. In Germany, file with your local Polizeidienststelle and the BKA. In France, use the PHAROS platform. In the Netherlands, file at politie.nl.

Other Jurisdictions

In Australia, report to the Australian Cyber Security Centre (ACSC) at cyber.gov.au and the Australian Competition and Consumer Commission (ACCC) Scamwatch. In Canada, file with the Canadian Anti-Fraud Centre (CAFC) at antifraudcentre-centreantifraude.ca. In Singapore, report to the Singapore Police Force online portal. Each country's enforcement capabilities and willingness to cooperate internationally vary, but filing broadly maximizes your chances.

6. Preparing Evidence for Maximum Impact

The quality of your evidence directly determines whether your case gets investigated. Law enforcement agencies are overwhelmed with reports, and cases with the best documentation are investigated first.

What Your Filing Should Include

A well-prepared complaint should include: all cryptocurrency addresses used by the scammer, all transaction hashes (TXIDs) of your payments, the total amount lost in both crypto and USD (with the exchange rate at the time of each transaction), exact dates and times of all payments, screenshots of all communications with the scammer, the URL and screenshots of any scam website, information about how the scammer contacted you, a professional blockchain analysis PDF documenting the fund flow, and any identifying information about the scammer (names, phone numbers, email addresses, even if likely fake).

Blockchain Analysis as Key Evidence

A professional blockchain analysis report is often the most powerful piece of evidence in a crypto fraud case. It transforms raw transaction data into a clear narrative that investigators can immediately understand: where funds came from, where they went through intermediary wallets, and where they ultimately landed (often at an identifiable exchange). This evidence bridges the gap between the pseudonymous blockchain and the real-world identity of the perpetrator.

7. Realistic Expectations

Managing expectations is important. Not every case will be actively investigated, and even investigated cases can take months or years to reach a resolution. However, filing is still essential for several reasons.

First, your case number enables bank chargebacks, exchange freeze requests, and insurance claims. Second, your report contributes to the intelligence picture. When multiple victims report the same scam operation, the aggregated loss reaches investigation thresholds. Third, your evidence is stored in law enforcement databases and can be retrieved if the same perpetrator is identified in another case. Fourth, filing with multiple agencies creates redundancy. If one agency declines to investigate, another may pick it up.

Factors that increase the likelihood of active investigation include: a significant loss amount, professional blockchain analysis showing funds reaching an identifiable exchange, multiple victims reporting the same scam address or website, parallel filings with multiple agencies, and engagement of an attorney who can apply additional pressure.
