1. Bank freezing:
there are mainly two kinds of bank freezing:
banks in some countries and regions do not allow bank accounts to participate in digital asset transactions (for example, because BTC, ETH, usdt, etc. are noted ring transfer, which causes the bank's risk control system to monitor), so when an account involves digital asset transactions, the bank will freeze or suspend part of the transaction authority
it is also possible that the behavior of this account triggered the bank's anti money laundering system (such as late night large amount transfer, frequent transactions with multiple people, no balance in the card for a long time, etc.)
generally speaking, the bank will not directly freeze the bank card, but will restrict your non counter business or "only pay but not collect", that is, suspend part of your transaction authority
how to deal with this situation:
directly contact the deposit bank and provide your relevant information (generally explaining the reasons for capital transactions) according to the bank's requirements
how to prevent this situation:
first, when dealing with the buyer, remind the other party not to remark sensitive words such as usdt and BTC
secondly, instead of using only one bank card, you can prepare more and change them over time
2. Judicial freezing:
the logic of judicial freezing is different according to different judicial proceres in different countries. But it's almost the same
after being cheated, the victim reports to the police, and the police freeze the bank accounts on the relevant fund line according to the bank account number of the victim's money. For example, the victim's money, called the bank account a, a called the bank account B, B called the bank account C, and then extended to D, e, F
then it is possible that a, B, C, D, e and F will be frozen, while B, C, D, e and F may not know the source of the funds
generally, the funds with problems are not frozen immediately after they are received. It may be because the transaction was frozen a month ago. But generally speaking, it's because a deal a few days ago was frozen
how to deal with this situation:
if the bank card is frozen by justice, you need to check how long the freezing period is and where it is frozen through the opening bank or the telephone hotline of the bank. These two information are very important. The bank background will display them. It's better to get these two information
most of the judicial freezes are only temporary and will be automatically unfrozen within two or three working days in cooperation with the police investigation. Don't worry about it. It will thaw automatically when it's e
but you should also pay attention to transfer the money when it is e, because it is possible that the involved case will not only have victims in one place, but also be frozen in more than one place, and it may be frozen again in the future. In addition, the 48 or 72 hours is not the time to thaw, some will be delayed for a few hours, or even half a day
the second one shows half year freezing. Generally speaking, if the funds with problems are directly received or are relatively close to the source of the funds with problems, they may be frozen for half a year. Of course, e to the different handling methods of the local judicial organs, in some areas, it is directly frozen for half a year
how to deal with this situation:
contact the local police as soon as possible and ask the police to provide information about suspected violations. Provide relevant information as required by local police. Relevant information is generally used to explain why the transfer of this fund occurs. Therefore, generally speaking, it includes the order records of OTC transactions within a certain period of time (you can log in to the hotcoin OTC account and click the order in the upper right corner to export and print)
when the above materials are provided to the police, they will give some feedback according to the different processing methods of the local public security systems and the different cases. For example, some cases can only be unfrozen if they are strictly required to be solved or withdrawn, some cases can only be frozen, and some cases can be unfrozen directly< Beijing Times News (reporter Yang Fenglin) the CBRC, the Supreme People's Procuratorate, the Ministry of public security and the Ministry of national security recently jointly issued the "provisions on banking financial institutions assisting the people's Procuratorate, the public security organ and the national security organ to inquire about freezing work" (hereinafter referred to as the "provisions"), It is proposed to comprehensively improve the efficiency of capital investigation and control by using cross regional collaborative query, large-scale centralized query and bank internal collaborative query
it is understood that in recent years, crimes such as telephone fraud, Internet fraud and stealing bank cards have occurred frequently. If criminals use remote telephone cards and bank accounts to commit crimes, it is difficult for the police to freeze the criminals' accounts in time after the victims report
according to the internal regulations of commercial banks, freezing bank accounts in other places requires local police to go to other places with freezing letters and letters of introction, and freeze them together with the police in other places. It takes at least one day to complete the procere. This not only gives criminals enough time to transfer the stolen money, but also increases the cost of handling the case
according to the regulations, if the procuratorial organs, public security organs and national security organs ask for more than the authority of inquiry or cross regional inquiry, the qualified financial institutions can submit the request to the superior institutions or other branches of the system for assistance, and feed back the inquiry through the internal proceres
the regulations also require that financial institutions should strictly keep confidential after receiving legal documents to assist in the inquiry and freezing of property, and it is strictly forbidden to inform the inquired and frozen units, indivials or third parties to help hide or transfer property The regulations have come into force since January 1 this year
