The situation description is very important, and many people do not know how to write it.

Regarding the freezing of XX bank card, please provide an explanation.
XX Public Security Bureau Criminal Investigation Brigade, XX Police Station, X Police Officer:
I, XX (male, Han nationality, born on XX, XX culture, ID number: XXXX, working at XX, living in XXX, phone number XX).
On XX/XX/XXXX, I discovered that my bank card, XXXX (card number), was frozen by the Criminal Investigation Brigade of the XX Public Security Bureau. After calling 110, I contacted Officer X (phone number: XXXX) and learned that on XX/XX/XXXX at XX:XX, XX transferred XX RMB to my bank, resulting in the freezing of my card.
About this transfer, here is an explanation:
I speculate in "Cryptocurrency Trading" on XX website through the C2C model, similar to a stock exchange. The currencies involved include "Bitcoin (BTC)" and "Tether (USDT)", among others. I aim to profit by buying low and selling high, which involves both gains and losses.
On XX month, XX day, at XX o'clock and XX minutes, XX purchased X USDT (USD) on the XX platform at a unit price of 7 yuan. The total value of the goods is XX yuan in Chinese currency. I was matched with XX through the XX platform system, but I don't know XXX.
Then I gave the card number to XXX in the chat box of the XX website system, and the other party made the payment to me. I delivered the goods (USDT) to the other party and the transaction is completed.
On XX month XX day, it was discovered that the bank card was frozen. After contacting Officer X, it was informed that this fund is suspected to be fraud-related. Then, attempted to contact the other party through XX website's third-party transfer phone but failed. Filed a complaint for the order, but unable to contact X.
Other laws and regulations:
In China, the legal status of cryptocurrencies such as Bitcoin is "virtual commodities", and the occupation, use, profit, and disposal related to them are also protected by the law. According to the notice issued by the People's Bank of China and other five ministries on preventing Bitcoin risks, cryptocurrencies such as Bitcoin are considered as internet commodity trading activities, and ordinary people have the freedom to participate in them at their own risk.
In conclusion, I am an innocent third party who was unaware and unknowingly sold an order allocated by the system on XX website, resulting in my bank card being frozen, which has had a huge impact on my life and work.
I have not engaged in any illegal activities. I request the public security organ to issue a document to exclude any suspicion of committing crimes and to unfreeze my bank account so that I can resume my normal life.
Explanation of the situation is very important and can be described based on your personal circumstances.
Cryptocurrency trading is not illegal, don't be afraid. As long as you can prove your innocence to Uncle, and it's just a case of accidental injury, the problem can be resolved.
Just take the execution power and implement it to solve the problem.
