When the Spanish authorities Dismantled an Ronne of Cristoca Journal of Cristoca Journal (≈ 542 million USD) In June 2025, Operation Borrelli was celebrated as one of the largest investment fraud into crypto in European history. More than 5,000 victims had been defrauded. Dozens of brilliance companies and payment processors have been exposed. Cryptographic portfolios and bank accounts related to an illegal product have been seized.
For those of us who worked in the application of laws and the information of blockchain, the point to remember the most important was not the size of the fraud. It was the message that coordinated and well -equipped agencies of the law can even dismantle the most sophisticated criminal networks in crypto.
Operation Borrelli demonstrates that cryptographic crime is not out of reach of the law. It is not out of reach when the institutions remain fragmented and the investigation teams are not prepared. The question is no longer whether these crimes can be resolved. The question is whether the world community community is ready to invest in their resolution.
The success of Spain was not a stroke of luck
The criminal company behind the Spanish withdrawal has followed a familiar and more and more dangerous game book. Frauders have used false cryptocurrency trading platforms to attract victims with high promises of yields. They have built confidence through campaigns by email, tax-free calls pretending to be financial advisers and even romantic scams. This type of long -standing manipulation, commonly known as “pork butcher”, has become one of the most effective methods to extract without distrust victims.
Once the deposits have been made, the money has disappeared in a very structured whitening network. The screens recorded in Hong Kong, synthetic identities and poorly regulated payment processors have all played a role. The funds were transported through crypto and portfolio exchanges in courts that lacked cooperation in terms of application. As the victims realized that they had been defrauded, the assets had often been superimposed on several blockchains and platforms, which makes them extremely difficult to follow without advanced tools.
Despite this complexity, the case opened. The Spanish Civil Guardia responded to early alert panels, in particular an increase in suspect transaction reports and complaints from Madrid and the Canary Islands. They launched a cross-border investigation involving Europol, France, Estonia and the United States. Together, they followed the union’s digital imprint on several continents.
This success was not just a question of collaboration. It depended on the deployment of technical expertise and the blockchain analysis. Europol’s financial crime specialists have worked directly with Spanish investigators to analyze portfolio activity, trace transactions and discover links between digital assets, business structures and payment processors. Internal security surveys have contributed to the preservation of evidence and helped to draw flows towards financial infrastructure beyond Europe. This coordinated effort has led to five arrests, five property searches and the seizure of cryptocurrency portfolios and traditional bank accounts suspected of holding criminal products.
The crime of the crypto thrives in the gaps between the courts
Too many jurisdictions always treat crime linked to cryptography as if it were too complex to continue or are not worth prioritizing. This approach leaves the door wide open to fraudsters. Although regulators have progressed by initiatives such as the European Union Mica framework or the directives of the financial action group on virtual assets, these rules alone do not result in a significant application unless the survey capacities catch up.
Criminal networks use gaps in regulations and compliance, often moving funds via payment processors who fail to detect suspicious behavior. Exchanges that neglect to monitor high -risk transactions or allow synthetic identities to create accounts also contribute to the problem. When the application is fragmented and the sharing of intelligence is slow, even basic whitening techniques can succeed.
Operation Borrelli has shown that this should not be the norm. The use of the SIENA of Europol platform has enabled the sharing of secure information in a timely manner through borders. The technical experts were integrated on site with the Spanish police, allowing investigators to respond to the tracks in real time. This level of coordination and speed is what made it possible to disrupt a large -scale cryptographic fraud program. It is a model that must be reproduced more widely.
Lessons learned: how Borrelli operation has succeeded
- Acted on early alert signs. Investigators moved when suspicious transaction reports and consumer complaints increased in Madrid and the Canary Islands.
- Build a cross -border team. Spain has coordinated with Europol, France, Estonia and the United States to follow money on the continents.
- Integrated technical experts. Financial crime specialists worked side by side with case agents to analyze portfolios and card flows to businesses and payment processors.
- Share intel secure used. SIENA has enabled information to exchange in a timely and secure manner, so the tracks were worked in real time.
- Protected proof and entered active. The team has kept digital evidence and entered cryptographic portfolios and bank accounts; The operation has produced arrests and properties research.
- Criminals technology with tools and training. The blockchain analysis and trained investigators have become a complex and transverse laundering in traceable evidence.

The police must be modernized or delay
Technology to investigate and pursue cryptographic crime already exists. Blockchain analysis tools can monitor transactions between channels, detect obscure models and produce eligible evidence in court. At Merkle Science, we work with agencies that strengthen these capacities from zero. What we often see is that when investigative teams receive the right tools and good training, their efficiency increases considerably.
However, technology is only part of the solution. Agencies must also modernize their internal structures. Financial crime units need digital asset specialists, data analysts and medical-legal examiners who can work together on rapid travel cases. Traditional survey models have not been built for crimes involving pseudonymous assets, multi-jurisdictional laundering or automated fraud campaigns. They must now be adapted to deal with these challenges.
Criminal actors are evolving. They use artificial intelligence to generate phishing campaigns, automate social engineering and clone legitimate financial platforms. They also take advantage of decentralized exchanges, pieces of confidentiality and sorrow to hide the movement of funds. Unless the police evolve at a similar pace, the gap will continue to widen.
It is not only a question of following innovation. It is a question of protecting the public. The victims of these scams are not only early adopters or cryptographic investors. They include retirees, owners of small businesses, students and families of workers. They are targeted because they can be manipulated, and they often find themselves with little appeal when their savings disappear.
A plan that must be global
The dismantling of the Spanish fraud ring should not be considered a punctual success. It should serve as a framework for future action. With trained investigators, behavior -based analysis, secure data exchange and international collaboration, large -scale cryptographic fraud can be studied and pursued effectively.
Now the challenge is to scale this model. Decision -makers must ensure that regulations are supported by application resources. Legislators should finance specialized working groups and provide tools that support real -time surveys. International organizations must continue to remove obstacles to information sharing and develop coherent standards on how virtual assets are monitored and studied.
The crypto is not intrinsically ingoverable. This becomes when institutions fail to follow. The technology used by criminals is not invisible. It is only effective when we choose not to look closely.
There is no shortage of fraud at the moment. The next case of a billion dollars is already in motion somewhere in the world. Whether he finds himself in court or disappears in a maze of screens and wallets will depend on whether we act on the lessons of Operation Borrelli.
