Why do exchanges freeze bank cards when selling U?

The reason is that some users involved in telecommunications fraud, illegal industries or Ponzi schemes use cryptocurrency trading as a way to launder money. They buy U through currency traders, and after laundering the illegally obtained funds, these funds may indirectly flow into the bank accounts of innocent sellers.

When investigating such cases, the police will track the flow of funds, resulting in the temporary freezing of bank cards, Alipay and other payment tools involved in the transaction.

If the capital chain involved is relatively clear and not directly derived from serious crimes, the unfreezing process may be smoother, and usually transaction records, bank statements and other materials need to be submitted, and part or all of the amount involved may need to be returned, and then the freeze may be lifted within a few days to half a year.

It is important to seek professional legal advice in such situations to ensure that the information provided can fully prove the individual's innocence, and actively cooperate with the investigation, which will help speed up the unfreezing process.

However, if the funds are directly related to serious crimes, even if detailed information is submitted, the difficulty of unfreezing will be greatly increased, and it may be necessary to wait for the case to be closed or accept further investigation by law enforcement agencies.

When encountering such an investigation for the first time, it is crucial to stay calm and avoid making inappropriate statements in a panic, so as not to aggravate the situation.
