Fraud in Cryptocurrency in Brazil

1. Cross-border trust and the investment proposition

A promoter may cultivate confidence through a shared language, community ties, a purported overseas trading business or apparent professional success. Those circumstances require verification; they establish neither legitimacy nor misconduct. Allegations must remain attached to identifiable representations and transactions. An assertion that a particular national community is responsible for a growing pattern of fraud requires reliable evidence, rather than inference from individual complaints.

Examine what was actually offered: direct ownership of cryptoassets, custody, a managed portfolio, an investment contract, foreign-exchange trading or access to a fictitious platform. These arrangements can engage different rules. References to continuous digital trading do not establish that every foreign-exchange market or service operates throughout the weekend, or that a platform permits withdrawals at all times.

The relevant warning signs concern verifiable conduct: guaranteed returns, unexplained custody arrangements, inconsistent company identities, pressure to transfer immediately, and demands for additional payments to release an alleged balance. A dashboard displaying profits is evidence of what the platform represented, rather than independent proof that the corresponding assets exist.

2. Brazilian criminal law: establish the offence and its territorial connection

Article 171-A of the Brazilian Criminal Code addresses fraudulent portfolio or intermediation activities involving virtual assets, securities or financial assets. Its elements include the pursuit of unlawful advantage, another person’s loss and deception through fraudulent means. A decline in market value or an unsuccessful investment does not, without more, establish those elements.

Under Articles 5 and 6, conduct occurring in Brazil and the location of its actual or intended result are relevant to the application of Brazilian criminal law. Article 7 provides distinct rules and conditions for conduct abroad. An overseas perpetrator or platform therefore calls for a territorial analysis; neither the victim’s nationality alone nor the use of a foreign server supplies a complete jurisdictional conclusion.

The chronology also matters. The applicable provision, any competing offences and the evidence required must be assessed against the conduct and the law applicable at the relevant time. A complaint should describe the promises, transfers, recipients and subsequent events accurately, leaving unsupported accusations and assumptions about corporate responsibility out of the factual account.

3. Regulation of virtual-asset services is a separate inquiry

Law No. 14,478/2022 establishes the Brazilian virtual-asset service framework, preserves the securities regulator’s competence and provides for consumer-law application where appropriate. Decree No. 11,563/2023 assigns regulation, authorisation and supervision of the relevant service providers to the Banco Central do Brasil, while preserving the distinct competences identified in the decree.

The Banco Central’s announcement of Resolutions BCB Nos. 519, 520 and 521 describes the authorisation, operation and specified foreign-exchange aspects of the framework that entered into force on 2 February 2026. The exact entity, service and applicable transitional position must be checked. A company registration, a pending application and an authorisation are different facts; none constitutes a guarantee against loss.

Where the arrangement concerns securities, the Comissão de Valores Mobiliários may have a role within its own remit. Its official investor service receives relevant complaints and reports, but the CVM expressly explains that it does not determine settlements, return assets or compensate individual losses. Regulatory reporting must therefore be distinguished from a claim for repayment and from a criminal complaint.

4. A United States connection requires more than an overseas address

The original discussion of United States offences remains relevant where the facts establish the required connection. 18 U.S.C. § 1343 concerns a fraudulent scheme and the use of interstate or foreign wire communications for its execution. An international message is not, by itself, a complete analysis of the offence, federal jurisdiction or the statute’s application to the particular conduct.

18 U.S.C. § 1956 contains separate money-laundering provisions with specified knowledge, transaction and purpose requirements. A concealment allegation must be connected to those elements; every onward transfer is not automatically money laundering. Subsection (f) also sets express conditions for extraterritorial jurisdiction, including a transaction threshold and different requirements concerning United States citizens and other defendants. Those conditions cannot be replaced by the general proposition that cryptocurrency moves across borders.

18 U.S.C. § 371 requires a conspiracy of the kind defined there and an act to effect its object. Mere association with a promoter does not establish participation in that agreement. Whether these or other provisions apply requires assessment by qualified counsel and the competent authorities; no particular charge, agency investigation or prosecution follows automatically from filing a report.

5. Preserve the transaction record before it disappears

The FBI’s guidance on reporting cryptocurrency investment fraud identifies transaction addresses, asset type, amount, date and time, and transaction hashes as useful evidence. Retain the original transfer records, platform identifiers, communications, domains and a chronological explanation of the interaction. Preserve exports and original files where available, alongside screenshots, so that the account can be checked against the underlying material.

Distinguish a platform account number, a deposit address, the blockchain network and the person alleged to control the funds. A transaction hash may establish a recorded movement on a particular network; attribution to a person, proof of beneficial ownership and the identification of recoverable assets require further evidence. A tracing report should explain its sources, assumptions and limits.

Use official channels to report the incident to the competent police authority and notify the bank or platform involved promptly, using independently verified contact details. Where there is a relevant United States connection, the Internet Crime Complaint Center is an FBI reporting channel. Submission preserves information for assessment; it does not assure an individual response, an investigation or reimbursement.

6. Criminal proceedings, protective measures and civil recovery

An investigation seeks to establish criminal responsibility. A civil claim seeks appropriate relief against a legally responsible person. A request to preserve assets aims to prevent an eventual remedy from becoming ineffective. Those objectives may overlap, but progress on one track does not establish success on the others.

For urgent civil relief in Brazil, Articles 300 and 301 of the Code of Civil Procedure provide a general framework requiring a sufficiently supported right and danger of harm or risk to the useful result of proceedings, with legally appropriate protective measures. The application must identify the requested order, the relevant evidence and its practical target. A lawyer’s letter or a private blockchain report is not itself a judicial seizure order.

Where assets, evidence or defendants are abroad, the route depends on the country, the type of proceeding and the assistance sought. Evidence gathering, recognition or enforcement of an order, and extradition serve different purposes. Extradition concerns a person’s surrender under the applicable legal conditions; it does not itself repay the victim. A Brazilian filing does not automatically freeze a foreign account.

A recovery assessment should identify the liable parties, assets that can realistically be reached, the cost of proceedings and potential competing claims. Even a favourable judgment does not establish that sufficient assets remain available. Predictions about recovery percentages or completion dates require a case-specific evidential basis.

7. Avoid a second loss through a purported recovery service

The FBI’s warning about cryptocurrency recovery schemes describes unsolicited approaches, upfront payment demands and false claims of official affiliation. Private providers cannot issue seizure orders. Verify the provider’s identity, professional status, written scope and fees independently before authorising work.

Do not disclose a wallet’s seed phrase, private key, password or active authentication code to someone claiming to trace or recover funds. A demand to deposit more cryptocurrency into an alleged official recovery wallet requires independent verification through the relevant authority’s published channel. A tracing service and legal representation must each be assessed on their own terms; neither should be presented as an FBI-endorsed recovery arrangement.

8. Choose institutions by function and jurisdiction

The useful starting points are the competent police authority, the bank or platform involved, the Banco Central or CVM where their respective remits apply, and the appropriate foreign reporting channel where there is a sufficient connection. Confirm each body’s remit before submitting material, particularly confidential account records.

Regulators, police bodies, international cooperation organisations, trade associations, research institutes and commercial blockchain-analysis companies perform different functions. Inclusion in a directory establishes neither an ability to receive an individual complaint nor an obligation to recover funds. The institutions cited above are linked for the specific role described; they are not endorsements of a service provider or substitutes for a jurisdiction-specific recovery strategy.
