In the USDT trading circle, anyone with a bit of experience knows that exchanges do not set limits on the buying and selling prices of U, leading to chaotic market prices. Some merchants buy at ridiculously low prices but sell at astonishingly high rates. For example, in a normal market fluctuation around 7.3, some merchants may buy as low as 7.1 and sell at 7.5, making a profit of 30 to 40 cents per transaction, far removed from the normal exchange rate range of RMB to USD.

Some people think this is normal market fluctuation, but in reality, such price manipulation hides significant risks. Once the transaction involves fraudulent funds, legal issues will follow. When handling criminal cases involving virtual currencies, authorities will not convict or detain individuals solely for trading virtual currencies; they are more concerned with whether there are any abnormalities in the trading process.

Depositing and withdrawing funds on exchanges is considered normal trading, but transferring to offline cash transactions may easily be viewed as abnormal. C2C order matching usually has a chat window, and WeChat chat records can serve as evidence, but if foreign chat software is used, the police may very well determine the transaction to be abnormal.

The key point is that placing orders at excessively high or low prices, significantly deviating from normal market prices, can lead to suspicion if fraudulent funds are involved. The police are likely to assume, based on relevant laws, that you are aware of the nature of the funds, which can lead to detention and being sent to a detention center. When criminal cases involving virtual currencies are submitted for legal review, reviewers focus on examining abnormal trading behavior, and once abnormalities are found, the likelihood of detention increases significantly. According to judicial interpretations of the crime of assisting in crime or concealing crime, prices that are abnormally low compared to market conditions are sufficient to presume subjective awareness. In other words, the price difference in orders after receiving illicit funds is likely to become a key factor that puts you in legal trouble.
