Core risks: Illegal capital and frozen credit cards
Whether the merchant's funds are clean
When you trade with a U merchant, you have no way of confirming whether the funds they give you are clean. These funds may be ordinary funds from a legitimate source, or they may involve fraud, money laundering or other illegal activities. Once the bank or relevant departments track down these funds, your account will be at risk of being frozen or even investigated.Hidden dangers of retroactive freezing
The risk does not stop at the moment of the transaction. Even if the current transaction seems normal, it may be frozen retroactively due to the other party's historical funding issues a few months or even years later. Some frozen card cases show that the time span may be as long as two years. Once the account is frozen, you need to provide sufficient evidence to prove the source of funds is innocent, which is a complicated and time-consuming process.Big data risk control monitoring.
The frequent inflow and outflow of funds by U merchants can easily trigger the bank's big data monitoring. After your account conducts transactions with these high-risk accounts, it may be marked as a risk account by the bank, leading to restrictions or freezing.Abnormal behavior of one's own account.
If your account suddenly shows large transactions and quick in and out, inconsistent with usual capital flow characteristics, the bank's risk control system will automatically trigger a warning. This situation is very likely to lead to account freezing.
Warnings from card freezing cases.
The risk of card freezing should not be underestimated. Here is a real case:
A friend completed a transaction with a U merchant two years ago. At that time, the funds seemed normal, but due to the historical fund involvement of the U merchant, his account was frozen by the bank two years later. When he tried to appeal, he found that the exchange he traded with had already closed down, making it impossible to provide the required transaction proof, leading to irretrievable losses.
Such cases indicate that whether funds will be traced and frozen entirely depends on whether the victim reports the case at a certain point in the future, or if the bank system triggers the trace.
The logic behind card freezing.
Issues with U merchant accounts.
Many U merchants' bank cards have been marked as high-risk accounts by the anti-fraud center due to long-term participation in high-frequency trading (such as USDT splitting and gambling, etc.). Your funds will be automatically associated with these accounts.The chain effect of funding sources.
If a black fund account transfers to a U merchant, and the U merchant transfers to you, even if it is a third-party account, it may be traced and frozen by the monitoring system.Abnormal operation of one's own account.
Quick in and out, frequent flow of large funds is likely to trigger bank risk control. Especially if there are unreasonable capital flows that do not match daily account records, it will trigger a bank investigation.
How to avoid risks?
1. Choose official platforms.
Prefer reputable OTC platforms, such as the official over-the-counter markets of large exchanges. These platforms will review the qualifications of merchants, significantly reducing the risk of involved illicit funds.
2. Withdraw in batches.
Withdrawing large amounts of funds at once is likely to trigger risk control. It is advisable to divide the funds into smaller amounts and conduct transactions at different times to avoid concentrating large amounts.
3. Pay attention to settlement time.
Do not immediately transfer withdrawn funds out; it is best to keep them in the account for a certain period to avoid being identified as abnormal quick in and out behavior.
4. Avoid frequent trading.
Reduce multiple transactions within a short period and try to maintain consistency with daily capital flow to lower the likelihood of being subjected to risk control.
5. Keep transaction receipts.
After completing a transaction, save all transaction records, including exchange records, U merchant payment screenshots, proof of funds source, etc. These materials are crucial in appeals for frozen accounts.
6. Use a professional card.
Reduce the use of your main personal bank card, and it is recommended to use a dedicated bank card for cryptocurrency transactions to lower the probability of affecting personal accounts.
Why was big data monitoring triggered?
Characteristics of U merchant behavior.
U merchant accounts are often used for high-frequency trading, with complex sources of funds, making them easily marked as high-risk accounts by the anti-fraud center. When your account interacts with these accounts, it will be automatically associated.Abnormal behavior
The big data risk control system will analyze the trading behavior of the account. If there suddenly appear large transactions with quick in and out, or the trading frequency is much higher than the daily level, it will be regarded as abnormal.On-chain risk
It is not just a simple issue of on-chain deposits and withdrawals, but rather the bank card being monitored by the anti-fraud center. This is due to high-frequency trading involving USDT or transactions with other marked accounts.
The consequences and responses to card freezing.
Consequences
Account funds frozen.
Detailed proof of funds source is required.
The investigation period may last for several months or even longer.
Response
Contact the bank immediately to understand the reason for the freeze.
Provide complete proof of funds source and transaction records.
Maintain good capital flow habits to avoid triggering risk control.
Summary
The withdrawal phase is a key step in converting cryptocurrency into real wealth, but it is also the riskiest part. Choosing compliant channels, diversifying transactions, keeping evidence, and being cautious with account operation habits are effective ways to reduce risk. Rather than risking fast withdrawals, it is better to focus on safety.
