Cryptocurrency trading has surged in popularity over the past decade, with Bitcoin leading the charge as the most recognized digital asset. While prices have fluctuated dramatically—plunging from nearly $20,000 per Bitcoin in 2017 to below $5,300 in mid-2018—the market rebounded strongly by 2019, with Bitcoin reclaiming the $10,000 mark on major exchanges like Huobi and OKX. Despite regulatory scrutiny, crypto trading continues to thrive in China and globally, drawing both retail investors and institutional players.
But with growth comes risk—especially legal and financial complications such as bank account freezes. Many investors find themselves caught in a legal gray zone: they’ve engaged in seemingly legitimate peer-to-peer cryptocurrency trades, only to discover their bank accounts frozen due to suspicious fund flows. This article explores why this happens, how to respond effectively, and what steps can be taken to protect your assets and regain control of your finances.
Is Cryptocurrency Trading Legal?
As of now, there is no explicit law in China that outright bans individuals from buying or selling cryptocurrencies. In fact, a joint statement issued on August 24, 2018, by key regulatory bodies—including the China Banking and Insurance Regulatory Commission (CBIRC), the Cyberspace Administration of China, the Ministry of Public Security, the People's Bank of China, and the State Administration for Market Regulation—focused primarily on cracking down on illegal fundraising schemes disguised as blockchain or virtual currency projects.
Notably, these regulations do not classify Bitcoin or other cryptocurrencies as illegal property. Instead, they emphasize risks associated with fraudulent platforms and initial coin offerings (ICOs). This means that under the principle of "what is not prohibited is permitted," private transactions between individuals—whether conducted on exchanges or over-the-counter (OTC)—are generally considered lawful.

However, legality does not equal immunity from enforcement actions.
Why Are Bank Accounts Being Frozen?
The core issue lies in the nature of cryptocurrency: decentralized, borderless, and often pseudonymous. These features make digital assets attractive not only to investors but also to criminals who exploit them for money laundering, especially in cases involving telecom fraud, online gambling, and ransomware payments.
When you sell Bitcoin or another cryptocurrency and receive fiat money into your bank account, there’s a real risk that the funds originated from illicit activity—even if the buyer appears legitimate. Since blockchain transactions obscure identity and traditional banks cannot easily trace the source of funds, any deposit linked—even remotely—to criminal proceeds may trigger an automatic freeze by law enforcement.
Law enforcement agencies use anti-money laundering (AML) protocols to trace suspicious transactions through banking records. If your account receives money that passed through a compromised chain—even unknowingly—you could become entangled in an investigation. The result? A frozen account, lost access to funds, and no clear path to resolution.
This phenomenon is colloquially known in the industry as “guan sha bu guan mai” (管杀不管埋)—a dark joke meaning “they freeze it but don’t bother to unfreeze it.” Once an account is flagged, it may remain frozen indefinitely without proactive intervention.
The Reality of Account Freezing: Delays, Bureaucracy, and Legal Gaps
Under Article 144 of China’s Criminal Procedure Law, investigative authorities—including public security bureaus and procuratorates—have the right to freeze bank deposits suspected of involvement in criminal activity. While this measure aims to preserve evidence and prevent asset dissipation, it often results in overreach:
- No notification required: Banks are not obligated to inform customers when an account is frozen.
- Indefinite extensions: Although standard freezes last six months, authorities can renew them repeatedly—some accounts remain frozen for years.
- Multiple jurisdictions: Different police departments across cities (e.g., Shanghai followed by Shenzhen) may successively freeze the same account, restarting the clock each time.
- Over-freezing: Amounts frozen often exceed the suspected illicit sum, affecting innocent savings.
Victims are left stranded—having delivered their crypto but unable to access their money—while struggling to identify which agency issued the freeze or how to appeal.
A Real Case: Successfully Unfreezing Over $300,000
Two months ago, a client reached out to our legal team after his bank account was frozen with more than RMB 2 million (~$300,000 USD) tied up. He had conducted routine OTC trades on a major exchange and believed all transactions were legitimate.
After thorough interviews and evidence review—including trade logs, chat records, transaction IDs, and wallet addresses—we prepared a detailed legal opinion outlining:
- The lawful nature of peer-to-peer crypto trading
- The absence of criminal intent
- Clear documentation proving clean transaction history
We submitted this package to the relevant investigative authority and coordinated with multiple departments to clarify the situation. Through persistent follow-up and legal advocacy, we secured the full release of the frozen funds after nearly seven months—and one renewal cycle—of restrictions.
This case underscores a critical point: proactive legal action is essential. Waiting for automatic unfreezing rarely works.
Practical Steps If Your Account Is Frozen
If you suspect or confirm your bank account has been frozen due to cryptocurrency activity, take these immediate actions:
1. Contact Your Bank
Request the following details:
- Name of the freezing authority (e.g., Public Security Bureau)
- Official case number or execution document ID
- Freeze start date and duration
- Total amount frozen
2. Gather Evidence
Compile all relevant materials:
- Screenshots of trade confirmations
- Messaging logs with counterparties
- Blockchain transaction hashes (TXIDs)
- Identity verification documents
- Proof of lawful income sources
3. Seek Specialized Legal Help
Engage a law firm experienced in blockchain-related financial disputes. General practitioners may lack familiarity with crypto transaction patterns or AML investigation procedures.

Frequently Asked Questions (FAQ)
Q: Does selling cryptocurrency make me a criminal if my account gets frozen?
A: No. Account freezing is an investigative tool, not a conviction. Being frozen doesn’t imply guilt—it means your funds passed through a suspicious channel. With proper evidence, most freezes can be lifted.
Q: Can I prevent my account from being frozen in the first place?
A: While no method guarantees 100% protection, using regulated exchanges with strong KYC/AML policies reduces risk. Avoid cash deposits or third-party intermediaries.
Q: How long does it take to unfreeze an account?
A: Timelines vary widely—from weeks to over a year—depending on jurisdiction and case complexity. Proactive legal engagement typically shortens the process.
Q: Should I talk directly to the police?
A: Proceed cautiously. Without legal representation, statements may be misinterpreted. Let your lawyer handle communications.
Q: Are all frozen funds recoverable?
A: In most cases where traders acted in good faith and can prove clean transactions, recovery is possible. However, delays are common.
Q: Can I still trade crypto after an account freeze?
A: Yes, but consider using different financial channels or platforms with enhanced compliance features to minimize future exposure.
