If you make a profit by trading $BTC and later, when you sell USDT on a certain platform, you receive suspicious funds transferred from the other party, resulting in your bank account being frozen by the authorities, you contact your uncle, who informs you that you must fully refund hundreds of thousands involved in the case to unfreeze your account, or if the victim does not accept your partial refund, how can you appeal for an unfreeze if you do not want to refund the full amount?

In this case, you generally submit appeal materials based on the legal regulations regarding freezing, appealing to the higher-level public security agency that issued the freeze and the same-level people's procuratorate, arguing that we are in good faith acquiring another person's property and should not be required to refund, stating that the requirement to refund in full after the freeze is inconsistent with legal regulations.

Then prepare a legal opinion letter, evidence of legal sources of funds, purchase orders, sales orders, chat records, bank transaction records, proof of employment, to demonstrate that personal trading of virtual currency is not illegal, and that the transactions meet the criteria for good faith acquisition, and submit this to the people's procuratorate. In some regions, the procuratorate's response time is 30 days, while in others it may take up to three months; by appealing through the people's procuratorate, you can strive to avoid a full refund or to reduce the amount required for unfreezing.
