¿Recibiste una? Por qué necesitas un abogado de defensa criminal — no solo un abogado de negocios.
Por Dennis Gonzalez Jr., Esq. — Ex-Fiscal de Miami-Dade | Abogado de Defensa Criminal Publicado el 1 de marzo de 2026 | (305) 209-0384 | dgonz.com Si eres dueño de un negocio en el Condado de Miami-Dade y tiene alguna conexión con Cuba — servicios de viaje, envío de carga, remesas, importación/exportación, telecomunicaciones, o cualquier otra actividad comercial que involucre la isla — es posible que hayas recibido una notificación de cumplimiento de la Oficina del Recaudador de Impuestos del Condado de Miami-Dade en las últimas semanas. No eres el único. Según la Oficina del Recaudador de Impuestos, 3,909 notificaciones de cumplimiento han sido enviadas a negocios de Miami-Dade con sospecha de estar involucrados en actividad comercial relacionada con Cuba. Las notificaciones exigen que confirmes si tu negocio realiza dicha actividad y, de ser así, que presentes documentación de autorización legal federal — incluyendo cualquier licencia o certificación de la Oficina de Control de Activos Extranjeros (OFAC) del Departamento del Tesoro de los EE.UU. o del Departamento de Comercio de los EE.UU. Muchos dueños de negocios están tratando esto como un trámite de rutina. Eso es un error grave. La forma en que respondas a esta notificación — o dejes de responder — puede determinar si enfrentas un simple problema administrativo o una investigación criminal federal. Como ex-fiscal de Miami-Dade y abogado de defensa criminal que sirve a la comunidad cubanoamericana, quiero explicarte exactamente lo que está pasando, por qué importa, y qué debes hacer ahora mismo. ¿Qué Son Estas Notificaciones de Cumplimiento?El Recaudador de Impuestos de Miami-Dade, Dariel Fernandez, ha estado realizando una revisión sistemática de negocios con posibles vínculos a operaciones comerciales relacionadas con Cuba. Este esfuerzo no comenzó de la noche a la mañana. La Oficina del Recaudador de Impuestos comenzó a enviar las primeras oleadas de cartas desde octubre de 2025, y para diciembre de 2025, a los negocios que no respondieron se les revocaron sus Recibos de Impuesto de Negocios Locales — efectivamente cerrándolos. La ola actual de 3,909 notificaciones representa una expansión dramática de este esfuerzo de cumplimiento. La base legal proviene de dos fuentes:
Añadiendo mayor urgencia, el Presidente Trump firmó una Orden Ejecutiva el 29 de enero de 2026, titulada “Abordando Amenazas a los Estados Unidos por el Gobierno de Cuba,” que declaró una emergencia nacional bajo la Ley de Poderes Económicos de Emergencia Internacional (IEEPA) y ordenó a las agencias federales intensificar la aplicación de las restricciones relacionadas con Cuba. La Página de Transparencia de Cumplimiento del Recaudador de Impuestos ha citado explícitamente esta Orden Ejecutiva como contexto adicional para su revisión ampliada. ¿Qué Pasa Si No Respondes — o Respondes Mal?Hay dos niveles de consecuencias, y la mayoría de los dueños de negocios solo entienden el primero. Nivel 1: Consecuencias Administrativas (Pérdida de Tu Licencia de Negocio)Si no respondes a la notificación de cumplimiento, o si no puedes demostrar autorización federal válida para tu actividad comercial relacionada con Cuba, el Recaudador de Impuestos revocará tu Recibo de Impuesto de Negocio Local. Esto no es una amenaza teórica. En diciembre de 2025, la Oficina del Recaudador de Impuestos revocó los Recibos de Impuesto de Negocios Locales de múltiples negocios, incluyendo agencias de viajes y compañías de multiservicios, que no respondieron a notificaciones anteriores. Sin un Recibo de Impuesto de Negocio Local válido, tu negocio no puede operar legalmente en el Condado de Miami-Dade. Punto. Nivel 2: Exposición Criminal Federal (Aquí Es Donde Se Pone Peligroso)Esto es lo que la mayoría de los dueños de negocios — e incluso muchos abogados — no aprecian completamente: la Oficina del Recaudador de Impuestos ha declarado que está coordinando con agencias federales responsables de la aplicación de sanciones y controles de exportación. Esto significa que tu respuesta a una notificación de cumplimiento del condado podría terminar en el escritorio de un fiscal federal. Las transacciones comerciales relacionadas con Cuba en los Estados Unidos están reguladas por las Regulaciones de Control de Activos Cubanos (CACR), 31 CFR Parte 515, administradas por OFAC bajo la autoridad de la Ley de Comercio con el Enemigo (TWEA), 50 U.S.C. §§ 4301–4341. Estas no son sugerencias. Son de las regulaciones de sanciones más estrictamente aplicadas en el mundo. Las penalidades criminales por violaciones intencionales son severas:
Lee eso otra vez: incluso si crees que la actividad de tu negocio es legal, proporcionar información inexacta o incompleta en tu respuesta podría crear responsabilidad criminal de manera independiente. Cómo una Notificación Administrativa Se Convierte en un Caso CriminalEste es un escenario que veo desarrollándose para los dueños de negocios de Miami-Dade en este momento:
Esto no es hipotético. Este es el sistema de cumplimiento que las autoridades federales y locales han construido. Y con 3,909 negocios ahora bajo revisión y un presidente en funciones que ha declarado una emergencia nacional específicamente dirigida a Cuba, el ambiente de cumplimiento nunca ha sido más agresivo. ⚠ ¿Recibiste una Notificación de Cumplimiento?

Por Qué Necesitas un Abogado de Defensa Criminal — No Solo un Abogado de NegociosLa mayoría de los abogados de negocios pueden ayudarte a llenar formularios y responder a una consulta administrativa. Pero esta situación requiere a alguien que entienda cómo las respuestas administrativas se convierten en evidencia en enjuiciamientos criminales — porque ese es exactamente el riesgo que enfrentas. Como ex-fiscal de Miami-Dade, sé exactamente cómo el gobierno construye sus casos. Sé qué buscan los investigadores en tus respuestas, qué lenguaje activa un escrutinio más profundo, y cómo declaraciones aparentemente inocentes pueden ser usadas en tu contra. También entiendo a la comunidad cubanoamericana porque soy parte de ella. Así es como puedo ayudarte:

La contratación de un abogado es una decisión importante que no debe basarse únicamente en anuncios publicitarios. You built your portfolio on Bitcoin before most people could spell “blockchain.” You staked Solana early. You moved ETH through DeFi protocols while traditional finance was still debating whether crypto was real. Then one morning, federal agents showed up at your door with a warrant—and suddenly your technical sophistication became the prosecution’s best weapon against you.
This scenario is no longer rare. The federal cryptocurrency enforcement landscape has shifted dramatically—the DOJ disbanded its dedicated crypto prosecution unit in April 2025 and narrowed its charging priorities, but that doesn’t mean the risk has disappeared. It means enforcement is now dispersed across individual U.S. Attorney’s Offices, the FBI, the IRS Criminal Investigation Division, and state prosecutors—making the threat harder to predict, not easier to ignore. People who operate in the digital asset space—from traders and miners to DeFi developers and NFT creators—still face a broad web of criminal liability. The charges range from money laundering and wire fraud to unlicensed money transmission and tax evasion. And most criminal defense attorneys are completely unprepared to handle them. The Technical Literacy Gap in Criminal DefenseHere’s the uncomfortable truth that most defense firms won’t tell you: when prosecutors bring crypto-related charges, they come armed with blockchain analysts, forensic examiners, and investigators from agencies like the IRS Criminal Investigation Division and the FBI’s Virtual Asset Exploitation Unit. The DOJ’s Computer Crime and Intellectual Property Section (CCIPS) continues to provide guidance, training, and coordination across federal prosecutor offices nationwide—and individual U.S. Attorney’s Offices in crypto-heavy jurisdictions like the Southern District of Florida remain aggressive. These teams understand wallet clustering, chain analysis, smart contract execution, and transaction graph mapping. Your defense attorney? Most of them are still Googling what a private key is. This isn’t a knock on criminal defense lawyers—it’s a structural problem. The legal profession wasn’t built for cases where the “crime scene” exists on an immutable distributed ledger, where the “weapon” is a smart contract, and where the “evidence” is a string of hexadecimal characters. When your attorney can’t meaningfully challenge the prosecution’s forensic blockchain analysis, you’ve already lost half the battle before trial. A Former Network Administrator Behind the Defense TableDennis Gonzalez Jr. isn’t a lawyer who took a weekend CLE course on cryptocurrency. Before law school, he worked as a network administrator—configuring servers, managing network infrastructure, troubleshooting packet-level issues, and understanding exactly how data moves across systems. That technical foundation didn’t disappear when he passed the bar. It became his most powerful tool. As a former prosecutor in Miami-Dade County, Gonzalez saw firsthand how the state builds cases—and where those cases are weakest. He knows the pressure points, the procedural shortcuts investigators take, and the technical assumptions prosecutors make when they don’t fully understand the technology they’re prosecuting. Now, from the defense side, that prosecutorial experience combined with genuine technical literacy creates a defense posture that most attorneys simply cannot replicate. This matters because crypto cases live and die on technical details. Can the prosecution actually prove that a specific wallet belongs to you? Did the chain analysis software correctly attribute transactions, or did it conflate mixer outputs with direct transfers? Was the smart contract interaction intentional or the result of a front-running bot? These are the questions that determine guilt or innocence—and you need a lawyer who can ask them with authority. The Charges Crypto Users Are Actually FacingThe range of criminal exposure in the crypto space is broader than most people realize. Federal prosecutors have been particularly aggressive, but Florida state charges are increasingly common as well. Here are the categories driving the most cases: Money Laundering (18 U.S.C. § 1956; Fla. Stat. § 896.101): Using cryptocurrency to conceal the origin of funds is the bread-and-butter charge in federal crypto prosecutions. Prosecutors leverage blockchain analytics tools like Chainalysis and CipherTrace to trace transaction flows. But these tools make assumptions about wallet ownership and transaction intent that are frequently flawed—and a technically literate defense attorney can expose those assumptions. Wire Fraud (18 U.S.C. § 1343): The government’s Swiss Army knife. If any electronic communication was involved in an alleged scheme—and in crypto, it always is—wire fraud charges follow. DeFi rug pulls, pump-and-dump schemes, and even legitimate projects that underperformed have all attracted wire fraud indictments. Unlicensed Money Transmission (18 U.S.C. § 1960): Operating a peer-to-peer crypto exchange, running an OTC desk, or even facilitating trades for friends and family can trigger federal money transmission charges. The threshold is lower than most people think. Historically, ignorance of the licensing requirement was not a defense. However, a significant shift occurred in April 2025: Deputy Attorney General Todd Blanche’s memo, “Ending Regulation By Prosecution,” now instructs federal prosecutors not to charge § 1960(b)(1)(A) and (B) violations unless there is evidence the defendant knew of the licensing requirement and willfully violated it. This narrowing does not eliminate the risk—the statute itself has not changed, and state prosecutors are not bound by DOJ policy—but it fundamentally alters the federal charging calculus. Understanding this shift is exactly the kind of current enforcement knowledge that separates effective defense from outdated advice. Tax Evasion (26 U.S.C. § 7201): The IRS has made cryptocurrency tax enforcement a top priority. Unreported staking rewards, DeFi yields, airdrops, and capital gains from trading are all fair game. The IRS Criminal Investigation Division now has dedicated blockchain forensics teams. Computer Fraud (18 U.S.C. § 1030; Fla. Stat. § 815.06): Smart contract exploits, unauthorized access to protocols, and even MEV (Miner Extractable Value) extraction have been prosecuted under computer fraud statutes originally written for hackers breaking into mainframes in the 1980s. The gap between what the statute covers and what crypto activity actually entails is where skilled defense wins cases. Securities Fraud and Unregistered Securities Offerings: Token issuers and promoters face criminal referrals following SEC enforcement actions. If you launched or promoted a token, participated in an ICO/IDO, or operated a DeFi protocol that the SEC considers a securities platform, criminal exposure remains real—though the DOJ’s April 2025 policy shift now instructs prosecutors to avoid cases requiring litigation over whether a digital asset qualifies as a “security” or “commodity” when alternative charges are available. The landscape is evolving rapidly, and your attorney needs to understand where the lines currently stand. The Shifting Federal Enforcement Landscape: Why It Matters More, Not LessIn April 2025, the DOJ issued a watershed policy memo that reshaped federal cryptocurrency enforcement. Deputy Attorney General Todd Blanche’s “Ending Regulation By Prosecution” memorandum disbanded the National Cryptocurrency Enforcement Team (NCET)—the specialized unit that had spearheaded major prosecutions including Binance, Tornado Cash, and BitMEX—and ordered the DOJ’s Market Integrity and Major Frauds Unit to cease cryptocurrency enforcement entirely. Some clients hear this and think the heat is off. That is a dangerous misreading. What the Blanche Memo actually did was redirect enforcement, not eliminate it. The DOJ continues to aggressively prosecute individuals who defraud digital asset investors and those who use cryptocurrency to further crimes like narcotics trafficking, terrorism financing, human trafficking, and cartel operations. In May 2025, a DOJ jury convicted the founder of SafeMoon on securities fraud, wire fraud, and money laundering charges. In February 2025, the Southern District of Florida indicted nine individuals for laundering cartel drug proceeds through cryptocurrency. IRS Criminal Investigation and the FBI’s blockchain forensics operations are entirely unaffected by DOJ policy memos. The practical effect for defendants is this: the enforcement landscape is now less centralized and less predictable. Without a single specialized unit coordinating crypto prosecutions, individual U.S. Attorney’s Offices are making independent charging decisions based on their own priorities and interpretations. The Computer Crime and Intellectual Property Section (CCIPS) continues to provide guidance, but the front lines have dispersed. This makes having defense counsel who monitors the current enforcement posture—not last year’s headlines—essential. What Technically Informed Defense Actually Looks LikeWhen Dennis Gonzalez Jr. reviews a crypto case, the analysis goes deeper than legal strategy. It starts with the technology itself: Challenging blockchain forensics: Chain analysis tools assign “attribution scores” to wallets, but these scores involve probabilistic modeling, not certainty. A defense attorney with network administration experience understands data flow, can interrogate the methodology, and can present expert testimony that exposes the gap between “likely attributed” and “proven beyond reasonable doubt.” Understanding transaction mechanics: Did the prosecution account for gas fees when calculating alleged proceeds? Did they understand that a failed transaction still shows on-chain? Did they distinguish between a token approval and a token transfer? These technical nuances can be the difference between a conviction and an acquittal. Network-level evidence: IP address evidence, VPN logs, node data, and metadata from wallet interactions all require technical interpretation. A former network administrator knows how IP attribution works—and how easily it can be wrong. Shared networks, dynamic IPs, and VPN services all create reasonable doubt that a technically illiterate attorney might miss entirely. Smart contract analysis: When the government alleges that a smart contract was designed to defraud, the defense needs someone who can read the code—or at least meaningfully engage with expert witnesses who do. Understanding the difference between a reentrancy exploit and a legitimate arbitrage play, between a backdoor function and a standard admin key, requires technical fluency that most defense attorneys lack. Why Miami Is Ground Zero for Crypto Criminal DefenseMiami has positioned itself as the crypto capital of the United States. From Bitcoin conferences to blockchain startups to crypto-friendly regulatory frameworks, the city has attracted a massive concentration of digital asset activity. But where money flows, enforcement follows. The Southern District of Florida has become one of the most active jurisdictions for cryptocurrency prosecutions, and Miami-Dade County state courts are seeing an increasing number of crypto-adjacent cases. Dennis Gonzalez Jr., P.A., based in Miami, operates at the epicenter of this intersection. Whether you’re a Bitcoin miner facing tax evasion allegations, a Solana DeFi developer under investigation for securities violations, an Ethereum smart contract creator accused of wire fraud, or a crypto trader targeted for money laundering, having a local attorney who understands both the federal and state landscape—and the technology underlying the charges—is not a luxury. It’s a necessity. The International DimensionCrypto doesn’t respect borders, and neither do federal investigations. Many crypto cases involve international transactions, offshore exchanges, and cross-border fund flows. For Miami’s large international community—particularly clients from Latin America and the Caribbean—the intersection of cryptocurrency charges and immigration consequences adds another critical layer of complexity. A conviction can trigger deportation proceedings, visa revocations, and permanent bars to reentry. Dennis Gonzalez Jr. routinely navigates these dual-track concerns, ensuring that criminal defense strategy accounts for immigration exposure at every stage. The Bottom LineIf you’re facing criminal charges related to cryptocurrency—whether it’s a federal indictment, a state investigation, or even a grand jury subpoena—you cannot afford an attorney who is learning about blockchain on your dime. The enforcement landscape is shifting rapidly: the DOJ has restructured its crypto prosecution apparatus, narrowed its charging priorities, and changed the rules—but the FBI, IRS-CI, and state prosecutors haven’t slowed down. You need a defense team that understands not just the technology, but where enforcement actually stands right now. Dennis Gonzalez Jr. brings a rare combination to the defense table: prosecutorial experience that reveals how the government builds these cases, network administration expertise that allows genuine technical challenge of digital evidence, and the aggressive advocacy that complex crypto cases demand.
