If you discover unknown funds received into your account in mainland China, you must immediately take protective measures. When facing the risk of run points money laundering, you should file an appeal at the earliest opportunity, proactively communicate with the bank, and report the matter to the police. You need to prepare relevant evidence to prove the funds are from legitimate sources. Fund isolation can effectively reduce the probability of account freezing. Through timely appeals, evidence preservation, and multi-layer wallet isolation, you can protect your fund security and avoid bearing joint liability.
If you discover unknown funds received into your account in mainland China, you must immediately take protective measures. Common signs of run points money laundering risk include frequent account inflows/outflows, involvement of suspicious funds, account freezing, or restrictions. Stay vigilant and promptly check account statements to avoid continuing to use the account for transactions.
You should proactively record all abnormal transaction information, including transaction time, amount, counterparty account, etc. Take screenshots of bank notifications and transaction details to provide evidence for subsequent appeals. After discovering abnormalities, do not transfer funds without authorization to avoid being deemed involved in run points money laundering.
You need to contact bank customer service or visit a branch as soon as possible to explain the receipt of suspicious funds in your account. Hong Kong licensed banks usually require you to provide detailed information, including transaction amounts, nature of suspicious activity, transaction purpose, etc. The table below shows the main information you should submit to the bank:
| Information Type | Description |
|---|---|
| Transaction Amount | At least $5,000 |
| Nature of Suspicious Activity | Funds involved in illegal activities or attempts to conceal or disguise illegal activities |
| Transaction Purpose | No commercial purpose or obvious legitimate purpose |
| Reporting Requirement | Submit using FinCEN SAR Form 111; confidential; must be filed within 30 days of initial detection |
You must notify the bank within 60 days after abnormal transactions appear on your bank statement. After receiving your appeal, the bank will initiate an investigation process. Generally, the bank completes a preliminary investigation within 10 business days. If the account was opened less than 30 days ago, the investigation period may be extended to 20 business days. If the bank confirms an error, it will correct the issue within one business day and provide investigation results to you within three days. If the investigation is not completed in time, the bank will issue provisional credit for disputed transactions, with a maximum deduction of $50. The bank must resolve the issue within 45 days, with an extension possible to 90 days in special circumstances.
If you suspect your account is involved in run points money laundering, you must report the matter to mainland China public security authorities. You can bring relevant evidence to the local police station or submit a report online through the public security platform. The police will require you to provide a written request, including formal documents from federal or local law enforcement agencies. The table below shows the main documents required for the police to initiate an investigation:
| Document Type | Description |
|---|---|
| Written request from federal law enforcement | Issued by a supervisory agent or attorney from the U.S. Attorney’s Office |
| Written request from state or local law enforcement | Issued by the head of the state or local agency or attorney from the prosecutor’s office |
You should cooperate with the police investigation, proactively explain the source of funds and transaction details. The police will review account statements to determine whether you bear joint liability. If you can prove you unknowingly received illicit funds, the police will file the case, reducing the risk of account freezing and legal accountability.
You must prepare sufficient evidence when appealing. You can collect the following materials:
You should ensure all evidence is authentic and valid, avoiding fabrication or omission. Organize the evidence chronologically to facilitate quick review by the bank and police. During the appeal process, the bank and police will focus on your fund flows and transaction purposes. If you can prove your innocence, the success rate of the appeal will significantly increase.
Tip: In run points money laundering cases, joint liability and frozen bank cards are common issues. You should promptly appeal, preserve evidence, proactively isolate funds, and protect your rights.
When facing run points money laundering risks in mainland China, you should prioritize official channels provided by Hong Kong licensed banks for appeals. Banks typically offer the following appeal methods:
The bank will require you to fill out an appeal form and describe the abnormal funds in detail. You must complete the appeal within 60 days after abnormal transactions appear in your account. After receiving the materials, the bank will initiate an investigation, generally taking 10 to 20 business days. You should promptly save all appeal records for follow-up.
If you discover suspicious funds in your account, you should immediately report the matter to mainland China public security authorities. You can choose the following methods:
You need to prepare transaction statements, bank notifications, personal identification, and other materials. The police will require you to provide detailed transaction details and verify the source of funds. You should proactively cooperate with the investigation and explain that you unknowingly received illicit funds. After the police file the case, it helps reduce legal accountability risks.
Evidence preparation is critical during the appeal process. You should pay attention to the following common errors:
In criminal appeals practice, procedural details are extremely important. Federal appeals courts have extremely strict technical requirements; any minor error may delay the appeal. You must follow rules and technical requirements, demonstrating respect for procedures, which helps improve the success rate of appeals.
You need to organize all evidence, including bank statements, freeze notifications, transaction screenshots, communication records, etc. It is recommended to archive them chronologically to facilitate quick review by the bank and police.
After submitting the appeal, you can track progress through the feedback channels of the bank and public security authorities. Banks and law enforcement agencies provide feedback based on different circumstances, as detailed below:
| Commenter Suggestion | FDIC Response |
|---|---|
| Allow continued supervisory appeals during formal enforcement action consideration or pendency | FDIC believes extending institutional appeal rights is valuable. |
| Suggest FDIC adopt expedited review procedures where appropriate | FDIC agrees that in certain circumstances, facts and circumstances of appeals will be considered. |
| Believe extension of appeal timeframes should occur only with institutional consent | FDIC states it will consider these suggestions. |
After you submit a DAML SAR, the FRA usually responds within 7 business days. The “cooling-off period” after a rejection notice is 30 calendar days. You should regularly follow up on appeal progress and save all feedback information to ensure your rights are not compromised.

You can effectively protect personal fund security through the multi-layer wallet isolation method. This method isolates high-risk funds into dedicated risk assessment wallets to avoid contaminating the main wallet. When managing assets, you adopt strict permission systems and signing strategies to prevent unauthorized access. The main wallet stores only core assets, while risk wallets handle unknown funds or high-risk transactions. Biyapay provides multi-layer wallet isolation solutions for Chinese-speaking users, helping you achieve layered asset management and improve overall security.
The multi-layer wallet isolation method not only reduces the probability of fund freezing but also enables you to quickly locate problematic wallets when encountering abnormal funds, minimizing losses.
You can adopt the following layered management strategies to enhance wallet security:
You can refer to Biyapay’s multi-layer wallet management features to flexibly configure signature strategies and permission assignments to meet different asset security needs.
Through the multi-layer wallet isolation method, you can effectively prevent account freezing risk. Separating high-risk funds from the main wallet avoids freezing of all assets due to unknown funds. You regularly review wallet structure and promptly adjust permissions and signature strategies to ensure asset security. When encountering abnormal funds, immediately isolate them to a risk wallet and pause main wallet transactions. You can also set automatic alerts to take immediate action upon detecting suspicious activity. The multi-layer wallet isolation method provides you with proactive protection, helping you safeguard funds in complex trading environments.
When handling abnormal funds, the practical order should be “isolate first, verify second, move later,” rather than rushing into another transfer or conversion. If you later need cross-border movement, a clearer statement of fund purpose, or a more consistent compliance trail, you can first review the official scope on the BiyaPay website, then use the remittance service and the currency converter and comparison tool to estimate transfer paths, conversion costs, and whether your supporting explanations remain consistent. As a multi-asset trading wallet, BiyaPay covers cross-border payments, investing, trading, and fund management scenarios, and it discloses relevant registrations and licensing information such as US MSB and New Zealand FSP. That kind of public information is more useful as part of a platform background check, especially when you need channels with clearer rules and more transparent fund routes during a sensitive funds review stage.
