Trading cryptocurrencies and being arrested: Under what circumstances is it not guilty?

If you are arrested for trading cryptocurrencies and receive a detention notice from the public security bureau in another location, stating charges of fraud or implied crimes, under what circumstances can you be considered not guilty?

First, if the other party is a U trader and your transaction does not have any other abnormal behavior, it cannot be presumed that you subjectively knew about it, then you are not guilty.

Second, if the other party is a victim who buys your U and then transfers the U to a scammer, this falls under the category of USDT transactions completed after the victim is scammed, which does not constitute a crime.

Third, if the other party is a victim who buys your U and directly transfers it to a scammer, this still requires judgment on whether the transaction has any abnormalities; if there are no abnormalities, it does not constitute a crime.

Fourth, if the other party's trading identity is a fleet, it also requires judgment on whether there are any anomalies in the trading behavior. The determination of whether the trading behavior is abnormal is based on judicial interpretations of implied crimes and aiding crimes, mainly looking at whether the trading price is the market price? Has there been any prior investigation by the public security bureau? Has the bank card ever been frozen? Have you fulfilled your due diligence obligations? Are encrypted chat software used? How did you know the trading counterpart? How long have you been in the virtual currency industry? And so on, to comprehensively judge whether there is subjective knowledge of guilt.
