In the digital money market, the most distressing thing is not the losses caused by price fluctuations, but the predicament where funds arrive yet cannot be withdrawn. This situation often leads to sleepless nights, far more worrying than a market fall.

Recently, an investor encountered such a dilemma: he withdrew 700,000 USDT from the exchange, but when the funds arrived in his bank account, he found that his card was restricted from non-counter transactions. This feeling of being able to see but not use it is more frustrating than a liquidation.

The main reason for this situation is the so-called "fund pollution." Some criminals convert their fraudulent gains into USDT and sell it to ordinary investors after multiple transfers. When victims report to the police, accounts along the entire fund chain may be frozen for investigation. It is important to note that having an account frozen does not mean the holder has committed a crime; rather, they have been implicated in the investigation. Usually, as long as relevant transaction proof can be provided, most accounts can ultimately be unfrozen, but this process can be both cumbersome and time-consuming.

To avoid this headache-inducing situation, investors should follow these several principles:

First, use a dedicated bank card for over-the-counter transactions and do not mix it with cards used for daily transactions. This can keep the cash flow clear and reduce risk management risks.

Secondly, carefully choose your trading counterpart. Prioritize reputable long-term accounts, and avoid trading with strangers or accounts with abnormally low fees just for small gains.

Finally, pay attention to the transaction details. Large amounts of funds should be transferred in batches; multiple small transfers are usually safer. The transfer remarks should use reasonable purpose descriptions, such as "consultation fee" or "service fee". After the funds arrive, it is best to wait a few days before using them.

Overall, in the cryptocurrency market, while making a profit is important, ensuring the safety of funds is fundamental. Market fluctuations are the norm, while the safety of funds is the bottom line that investors should uphold. The real challenge lies not in making profits, but in how to safely realize and utilize those profits.
