Hong Kong OTC Virtual Asset Trading: Legal Risks and Compliance Tips Every Retail Investor Must Know

According to the latest data, Hong Kong’s cryptocurrency market is developing rapidly and has become a major global trading hub. In virtual asset trading, OTC (over-the-counter) transactions are favored by many retail investors due to their flexibility and convenience. However, Hong Kong’s OTC trading environment is complex and constantly changing, involving cross-border regulation, data security, tax compliance, and other challenges. This article will analyze the core risks and self-protection strategies for retail investors from a legal professional perspective.

Current Situation of Hong Kong’s OTC Market: Why Retail Investors Prefer Off-Exchange Trading

Definition and Characteristics of OTC Trading

Over-the-counter (OTC) trading refers to transactions conducted directly between two parties or through intermediaries, without using a centralized exchange. Unlike on-exchange trading, which relies on the exchange’s credit guarantees, OTC trading is based on mutual trust between the parties.

Retail investors typically refer to individuals trading virtual currencies with small amounts of their own funds. According to the Hong Kong government’s 2024 proposed legislation on virtual asset OTC trading, “virtual asset OTC trading business” refers to providing spot virtual asset trading services in a commercial manner. Notably, peer-to-peer virtual asset buying and selling for non-commercial purposes is not subject to licensing restrictions. However, this does not mean OTC trading by retail investors is completely risk-free.

Cryptocurrency OTC trading offers three main advantages: reducing price slippage, increasing trading flexibility, and lowering participation barriers. These features are especially friendly to newcomers, but they also conceal legal and security risks.

Forms of OTC Trading in Hong Kong

Based on observations and statistics from law enforcement agencies, Hong Kong’s OTC virtual asset trading currently exhibits diverse patterns:

Online trading: Conducted via blockchain technology and P2P platforms, where platforms act as matchmakers but do not handle funds directly; instead, funds transfer through other payment channels. Examples include OTC DEX platforms widely used on major exchanges like OKEx.

Offline trading: Face-to-face transactions based on local networks, including virtual asset exchange shops and ATM services on the streets of Hong Kong. Preliminary statistics indicate about 200 physical OTC shops (including ATM-based) operating in Hong Kong, with around 250 active virtual asset service providers online.

This hybrid online-offline OTC ecosystem provides convenience for retail investors but also broadens potential risks.

Three Major Hidden Dangers: Legal and Security Risks in OTC Trading

Risk One: Illegal Activities and Regulatory Traps

Money laundering and counter-terrorism financing risks

A core risk in Hong Kong OTC trading is the source of funds. Due to its decentralized nature, OTC trading can be exploited for illegal fund transfers without the participants realizing it.

In practice, some malicious actors use OTC platforms to:

• Attract inexperienced retail investors with favorable prices to accept suspicious sources of virtual currencies
• Turn retail investors into intermediaries for transferring stolen assets
• Conduct money laundering or terrorist financing activities via OTC platforms

Under Hong Kong’s Anti-Money Laundering and Counter-Terrorist Financing Ordinance, engaging in OTC transactions with suspicious counterparts can lead to criminal liability. Even if retail investors are unaware of illegal activities, they may be held responsible if they “knowingly participate.”

Cross-border foreign exchange control risks

Hong Kong OTC transactions frequently involve exchanges between fiat currency and virtual currencies. A key issue is: Does virtual currency constitute “foreign exchange”?

According to the “Regulations of the People’s Republic of China on Foreign Exchange Administration,” illegal foreign exchange trading or disguised foreign exchange trading is unlawful. If retail investors use virtual currencies as a medium to convert through “foreign exchange → virtual currency → RMB,” effectively engaging in cross-border value transfer, it may be considered disguised foreign exchange trading, risking criminal charges for illegal operation.

This poses significant legal risks for retail investors frequently involved in cross-border OTC trades.

Tax compliance risks: Hidden costs

Many retail investors overlook an important fact: Hong Kong has clear tax requirements for virtual currency transactions.

According to the Hong Kong Inland Revenue Department’s DIPN 39, “cryptocurrency business” includes:

• Cryptocurrency trading
• Cryptocurrency exchange
• Cryptocurrency mining

Profits derived from cryptocurrency activities originating in Hong Kong are subject to profits tax. Hong Kong applies a territorial source principle: even non-residents must pay tax on profits from business activities conducted in Hong Kong.

Tax rates are as follows:

Based on Deloitte’s 2024 tax guide, Hong Kong has a two-tier profits tax system:

• First HK$2 million of assessable profits: 7.5%
• Amount exceeding HK$2 million: 15%

Consequences of non-compliance are severe:

• Fixed fine of HK$10,000
• Penalties up to three times the unpaid tax
• In serious cases, imprisonment for up to three years

While occasional or small-scale transactions may be less scrutinized, frequent and large OTC trades make tax compliance an unavoidable issue.

Risk Two: Personal Data Leakage and Platform Security

Technical risks from complex transaction processes

OTC trading involves large sums and digital assets transfer, with technical complexities far beyond ordinary transactions. Risks include:

• Blockchain layer: network congestion, wallet security vulnerabilities, transaction confirmation delays
• Administrative layer: improper identity verification, unregulated smart contracts, chaotic transaction record management

Platform security vulnerabilities and data breaches

Some OTC providers lack adequate security measures, leading to issues such as:

• Security flaws in third-party platforms susceptible to hacking
• Unauthorized access to user identities, transaction details, and asset information
• Phishing attacks and malware exploiting platform vulnerabilities to steal user data

For example, in 2021, prominent exchange Huobi was publicly exposed by security researchers for potential information leaks involving OTC transaction data, large account details, and internal architecture. Although Huobi later clarified that no large-scale breach occurred, this incident highlights risks even for well-known platforms.

Worse, some unscrupulous OTC platforms may sell user data to third parties, becoming sources of scams and further criminal activities.

Risk Three: Trading Losses and Trust Breakdown

Amplified trust risks

Unlike centralized exchanges with escrow and guarantees, OTC trading relies entirely on mutual trust. Once trust erodes, parties may face:

• Default or delayed fulfillment
• Partial or non-performance
• Misunderstandings due to information asymmetry

Common scams include:

Fraudulent refunds — the most common scam in OTC markets. After receiving virtual assets, the counterparty immediately revokes or reverses the payment, causing losses to the retail investor.

Fake identities and exaggerated capabilities — scammers fabricate identities, claim to deliver large quantities of virtual assets, or boast of false financial strength, deceiving investors into false agreements.

Broker insolvency or fraud — intermediaries responsible for matching trades may go bankrupt or commit fraud, leading to chain reactions where all participants suffer losses. Any collapse of trust can severely damage the entire market ecosystem.

Cross-border transaction complexities

In cross-border OTC trading between Mainland China and Hong Kong, risks multiply due to:

• Divergent legal systems and regulatory frameworks
• Ambiguous jurisdiction, making legal remedies difficult
• Language barriers and inconsistent documentation
• Conflicting legal interpretations increasing misunderstandings
