Anyone who has traded USDT knows that exchanges do not impose restrictions on the buying and selling prices of U. Some merchants have very low purchase prices and very high selling prices. For example, in a normal market, it fluctuates around 7.3; they might set a buy price of 7.1 while the selling price is above the market price, possibly reaching 7.5. This creates a price difference of 3-4 cents, which is obviously lower or higher than the exchange rate of the RMB to the USD.

Some may say this is market behavior, but what legal issues arise if fraudulent funds are involved? In cases involving criminal activities related to virtual currencies, investigators will not directly convict you or detain you based solely on your trading of virtual currencies; instead, they will look for issues within your transactions.

A common comparison is that if you deposit and withdraw funds at an exchange, it is considered normal trading. However, if you transfer to cash transactions offline, it may seem suspicious. In C2C order matching, there are always chat windows; at the very least, you have WeChat conversations. But if you use an overseas chat application, investigators may deem your trading behavior as suspicious.

Returning to the main discussion point, if your order prices are significantly higher or lower than normal prices, and you receive funds linked to fraud, it will be presumed that you knowingly accepted those funds, which could lead to detention. All criminal cases involving virtual currencies are reviewed legally to determine if there are any abnormal behaviors; if such behaviors are identified, your detention will be approved.

According to judicial interpretations of the crime of assisting in criminal activities or concealing crimes, prices that are abnormally low compared to market conditions can lead to a presumption of your subjective knowledge. This means that the price difference in your orders, after receiving the illicit funds, will become a crucial factor against you.
