The US authorities have confiscated $15 billion worth of bitcoins, seized from an international fraud ring operating mainly in Asia. GetBlock AML Research explains how the US became $15 billion richer in just one day.
The United States and the United Kingdom have reported on the largest joint operation in history against a large-scale network of online fraud, human trafficking, and money laundering through cryptocurrency in Southeast Asia.
The operation was unprecedented in its scale and covered several areas simultaneously — including criminal charges, sanctions, and financial measures.
US prosecutors have charged prominent Cambodian businessman Chen Zhi, owner of the Prince Group holding company, with creating a global network of fraud and forced labor.
The US Department of Justice announced the largest seizure in history — 127 271 bitcoins worth approximately $15 billion. The US Department of the Treasury imposed sanctions on 146 individuals and companies associated with the Prince Group network.
In addition, a separate decision by the Financial Management Department recognized another Cambodian company, Huione Group, as an organization involved in large-scale money laundering.

At the same time, the UK froze the assets of those involved and imposed a ban on entry into the country for a number of individuals. All of this became part of an overall strategy to destroy the international infrastructure of criminal schemes.
In recent years, scammers in Southeast Asia have created a huge industry of deception — from fake investments to “romantic” schemes, where victims are deceived through trusting relationships on the internet. It is estimated that tens of billions of dollars have passed through such schemes.

How the Prince Group network operates
At the center of the investigation is Chen Zhi, a Cambodian citizen and the head of the Prince Group holding company. According to investigators, he and his partners ran a multi-billion dollar scheme in which thousands of people were held in special camps in Cambodia, Myanmar, and Laos.

Victims were forced to participate in fraudulent schemes, posing as investors or “partners” on the internet and luring other people into fake crypto investment projects.
Many of these centers were guarded by armed men. Workers were beaten, sold to other groups, or forced to work.
US sanctions
At the same time, the US Treasury Department imposed broad sanctions against 146 individuals and companies associated with the so-called “Prince Group transnational criminal organization.” Among those named are Chen Zhi himself, his top managers, and dozens of front companies registered in Cambodia, Hong Kong, Singapore, the British Virgin Islands, and the UAE.
Key companies in the holding group — Prince Bank Plc, Prince Real Estate Group, and their subsidiaries. The sanctions mean that all assets of these individuals and organizations in the United States are frozen, and American citizens and companies are prohibited from conducting any financial transactions with them.
In addition, four bitcoin wallets used to transfer and conceal funds obtained from fraudulent schemes were added to the sanctions list. These wallets are now blocked for all regulated exchanges and services worldwide.
Huione Group recognized as a money laundering hub
On the same day, US authorities took an additional step: Huione Group, also based in Cambodia, was officially recognized as a participant in international money laundering schemes.

The investigation found that billions of dollars in suspicious transfers linked to internet fraud, human trafficking, and cybercrime passed through Huione’s structures. According to the authorities, some of Huione’s operations were used to conceal funds stolen by hackers linked to North Korea.

Following this decision, US banks are prohibited from working with the Huione Group, effectively cutting the company off from the international financial system.
Charges and record confiscation
The US Department of Justice has brought criminal charges against Chen Zhi for fraud and money laundering. According to the prosecution, people were held against their will in camps under his control and forced to deceive investors from around the world, luring them into fake crypto investments. Chen Zhi himself is on the run.
At the same time, the US prosecutor’s office filed a civil suit to confiscate 127 271 bitcoins (approximately $15 billion) — funds obtained through fraud and money laundering.
These bitcoins were stored in 25 crypto wallets managed by the defendant himself. They are now under the control of the US government. This is the largest confiscation in the history of the US Department of Justice.

What will happen to confiscated bitcoins
Bitcoins seized by the US government are now held in the US strategic crypto reserve.
Why the US is considering such a reserve
In recent years, US law enforcement agencies and other departments have increasingly gained control of large amounts of cryptocurrency as a result of investigations (extortion, dark web, theft, money laundering). At the same time, digital asset regulation policies have developed, along with interest in using seized crypto assets not just as “frozen” evidence, but as part of financial resources that can be accumulated and, in certain scenarios, used in government policy. At the level of the administration and relevant agencies, documents and discussions have appeared calling for the creation of targeted approaches to the management of “state crypto assets,” including ensuring transparency, storage, and the possibility of use in the interests of the state.
Which cryptocurrencies can be included in the reserve? In practice, the most liquid and widely used assets are considered first in such a basket:
- Bitcoin (BTC) — the main bet for long-term storage and “strategic” reserve;
- Ethereum (ETH) — the second currency in terms of capitalization and liquidity;
- large liquid tokens (USDC/USDT for trading operations, possibly Solana, XRP, ADA, etc.), if legislation and internal policy allow them to be held/transferred. The choice will depend on liquidity, legal restrictions, and objectives: value storage, use in interdepartmental operations, compensation to victims, etc.
What does the US crypto reserve consist of?
The main sources are major criminal cases and civil forfeiture lawsuits: the closure of dark web markets (Silk Road, etc.), seizures from hackers and fraudsters (e.g., as a result of exchange hacks or mass fraud), as well as property prosecutions in the context of sanctions and criminal cases.
