Trading cryptocurrency for U and selling U leads to arrest, and a detention notice from a different jurisdiction has been received, stating charges of fraud or concealment. Under these circumstances, which situations are considered not guilty?

First, if the other party's identity is a U trader, and your transaction does not involve any other abnormal behavior, it cannot be presumed that you subjectively knew, thus you are not guilty.

Second, if the other party is a victim, they buy U from you, and then transfer the U to a scammer, this falls under the category where the USDT transaction is completed, and the victim is scammed out of U, which does not constitute a crime.

Third, if the other party is a victim and they buy U from you and directly transfer it to a scammer, this also requires judgment on whether the transaction had any abnormalities; if there are no abnormalities, it does not constitute a crime.

In the fourth case, if the other party's identity is a fleet, it also needs to be determined whether the transaction behavior shows any abnormalities. Whether the transaction behavior is abnormal is based on judicial explanations of hidden crimes and aiding crimes, mainly looking at whether the transaction price is at market price, whether it has been investigated by law enforcement before, whether the bank card has ever been frozen, whether due diligence has been performed, whether encrypted chat software was used, how you got to know the transaction counterparty, how long you have been involved in the virtual currency industry, etc., to comprehensively judge whether there was subjective awareness. $BTC
