If you profit from trading $BTC coins and sell USDT through a certain exchange, receiving transferred funds related to fraud, which leads to your bank card being judicially frozen, you contact your uncle. Your uncle informs you that the amount involved in the case must be fully refunded for the freeze to be lifted, or if the victim does not accept your partial refund, and you do not want to refund the full amount, how can you appeal to unfreeze it?

In this case, it is generally necessary to submit appeal materials based on the legal provisions regarding freezing to the higher-level public security organ and the same level people's procuratorate, arguing that we belong to the good faith acquisition of others' property, and that the request for a full refund after freezing is not in accordance with legal provisions.

Then prepare a legal opinion letter, proving the legal source of funds, purchase orders, sale orders, chat records, bank transaction records, work certificates, to demonstrate that personal trading of virtual currency is not illegal, and that the transactions comply with good faith acquisition. Submit this to the people's procuratorate. In some regions, the response time from the procuratorate is 30 days, while in others, it is three months. By appealing through the people's procuratorate, you can strive to not refund or to minimize the refund for the unfreeze.
