Introduction: High-Profile Crackdowns on Crypto Crime

In early 2026, international law enforcement agencies concluded two landmark investigations into global crypto fraud, underscoring both the determination to combat cross-border financial crime and the growing urgency of digital asset security.

Chen Zhi, accused of orchestrating a vast transnational crypto fraud and money-laundering network, controlled the Prince Group, which operated more than ten scam compounds in Cambodia. Through large-scale “pig-butchering” schemes, the network defrauded victims worldwide of billions of dollars. After years of investigation, U.S. authorities seized nearly 127,000 bitcoins linked to Chen—worth approximately USD 15 billion—the largest Bitcoin seizure in U.S. history and a milestone in global anti-crypto-crime enforcement.

Just ten days later, Cambodian police arrested another major scam figure, Huang Jimao , who allegedly ran the Royal Park scam complex and cross-border networks that lured victims into fake crypto investment schemes.

According to U.S. Treasury data, total losses from online investment fraud in recent years exceed USD 16.6 billion. Due to their anonymity and cross-border liquidity, crypto assets have become a primary vehicle for fraud and laundering—making systemic risk impossible to ignore.

Investigation and On-Chain Tracing: Not a Tech Myth, but a Governance Challenge

The Chen Zhi case is emblematic. The suspect dispersed massive Bitcoin holdings across 25 non-custodial wallets, attempting to obscure fund flows through fragmentation. Law enforcement agencies, working with blockchain analytics firms such as Chainalysis, spent years reconstructing transaction paths using cross-chain tracking and transaction graph analysis—ultimately freezing and confiscating the full amount.

This process reveals three core realities:

1. On-chain transparency does not equal safety. While blockchain data is public, the absence of coordinated regulation allows criminals to exploit mixers and cross-chain bridges.

2. Technology requires institutional backing. On-chain data has no legal force on its own; only judicial authorization and cross-border cooperation can turn data into enforceable evidence.

3. Technology is essential—but not sufficient. Tools such as OKLink’s on-chain monitoring (used in the USD 540 million RenBridge laundering case) and Deloitte’s blockchain audit systems are effective only when embedded in compliant legal and operational frameworks.

Scams and Everyday User Risk

Beyond high-profile criminal syndicates, crypto fraud targeting ordinary investors is often more subtle—and more damaging.

In Singapore, a fake mining machine Ponzi scheme promised “30% annual returns,” siphoning thousands of investors’ funds into offshore wallets with no possibility of recovery. In the U.S., “romance scams + crypto ATMs” surged, with losses reaching USD 246.7 million in 2024, and nearly matching that figure within the first seven months of 2025. Illicit transactions at crypto ATMs far exceed industry averages.

Mainland China has seen similar cases. In Jiangsu, two women fell victim to pig-butchering scams; one invested over RMB 700,000, with RMB 160,000 permanently lost after being transferred to overseas wallets.

These cases demonstrate a harsh reality: fraud risk permeates the entire crypto investment lifecycle, and the irreversibility of on-chain transactions leaves victims with little chance of recovery.

Traceable Does Not Mean Controllable

A common misconception persists: that transparent blockchains guarantee security. In practice, a wide gap exists between on-chain visibility and real-world control:

• Public addresses cannot prevent illicit transfers. Once a transaction is confirmed, it is irreversible. FBI data shows crypto fraud recovery rates below 10%, far lower than in traditional finance.

• Assets may be frozen by association. Even compliant users can face temporary freezes if their wallets receive tainted funds indirectly—as seen in the Chen Zhi case, where legitimate assets were frozen before eventual release through lengthy procedures.

• Exit risk is constant. Counterparty exposure, non-compliant platforms, or blacklisted flows can result in blocked withdrawals or account closures.

Compliance and Risk Management: The Institutional Perspective

These cases highlight a central truth: digital asset risk is a compound of technical and institutional risk, and regulatory compliance is now the industry’s primary bottleneck.

For institutions and large holders, private key control and on-chain transparency alone are insufficient. Entry into mainstream finance requires three foundations:

1. Clear asset ownership definition. The EU’s MiCA regulation mandates robust asset registration by Crypto-Asset Service Providers (CASPs) to ensure traceable and verifiable ownership.

2. Institutional AML/KYC and risk controls. FATF requires all VASPs to implement strict AML/KYC procedures and suspicious transaction monitoring.

3. Auditable, compliant custody. The U.S. SEC requires digital asset funds managing over USD 100 million to use qualified custodians; MiCA similarly sets capital and risk standards for custodians.

Why Custody Matters: From Risk Avoidance to Institutional Governance

Professional custody bridges the gap between technological security and regulatory expectations in three key ways:

• Asset segregation. Legal structures separate client assets from institutional balance sheets, preventing misuse or commingling.

• Reduced compliance and fraud exposure. Custodians integrate AML/KYC systems and blockchain blacklist databases for real-time transaction screening.

• A trusted asset governance framework. Beyond key management, custody enables lawful inheritance, audits, and dispute resolution—addressing the fatal flaw of self-custody, where lost keys mean permanent loss.

As cross-border regulation tightens, custody has become foundational infrastructure for integrating digital assets into mainstream finance. The Bank for International Settlements has identified compliant custody as a key mechanism for resolving the disconnect between technical innovation and institutional safety.

From Enforcement to Infrastructure

The arrests of Chen Zhi and Huang Jimao send a clear message: on-chain transparency cannot replace legal accountability, and private key security cannot substitute for compliant risk management.

With MiCA coming into force in Europe, enhanced SEC oversight in the U.S., and Hong Kong’s Digital Asset Policy Statement 2.0 accelerating compliance, the industry is entering a new phase. In this transition, GDC provides four core safeguards through trust-based custody and compliance services:

• Stronger asset segregation to prevent risk contagion;

• Audit-ready compliance infrastructure aligned with global regulation;

• Robust risk management to avoid exposure to illicit activity;

• Compliant exit and liquidity pathways for lawful asset realization.

Only through such frameworks can digital assets move beyond being mere “on-chain records” to become controllable, credible, accountable, and realizable components of real-world wealth, enabling sustainable and healthy industry growth.
