Casino black u uses a surge in the flow of funds into the exchange, causing a large number of accounts to be passive. How to prevent it? Before you start, you are welcome to use the exchange's highest rebate registration link or invitation code below the video. Your support is my motivation to update. Since the national card-cutting operation was launched in October 2020, it has become a common understanding in the industry that black and gray industries have used cryptocurrency transactions to launder money. Investors are well aware of the current situation that receiving black and gray funds may lead to frozen cards or even suspected of Bangxin. USD generated based on blockchain technology has a certain degree of adoption in the money laundering links of many upstream crimes due to its high liquidity and concealment characteristics, including online gambling, extortion, drug trafficking, theft, fraud, violence and terrorism. These USD related to illegal activities are defined as Hayu by the industry. According to the exposure of Hayu, we further divide the source addresses into two categories. One is the address associated with on-chain security incidents mainly caused by hacker attacks. Because of the widespread attention of the industry, these addresses are often marked by major data platforms or AML platforms immediately after the accident. The other category is the on-chain fund addresses of various black and gray industries. The illegal activities of this type of black and gray industries are often secretive and niche, and their on-chain fund flows are rarely mined by mainstream data analysis platforms, but they still have an impact on the address security of normal users.

Take the use of USD in online gambling platforms as an example. It is illegal to provide any form of online gambling business to Chinese citizens. Some online gambling institutions set up overseas have not attracted Chinese users and at the same time circumvented the fund tracking of law enforcement agencies. , allowing gamblers to use USD as a deposit and withdrawal tool. Normal USD will be contaminated after entering the fund pool of the online gambling website, and spread through user withdrawals, causing harm to normal users' addresses and exchange accounts.

This type of gambling website generally supports gamblers' UST recharge and withdrawal, as well as the online gambling platform's own fund settlement, by connecting to the cryptocurrency four-party payment platform. Black and gray USD is transferred to the addresses of ordinary on-chain users and exchange users through gamblers withdrawing funds and platforms transferring profits.

How to avoid black u?

Based on the Beatrice team's long-term experience in cooperation with regulatory and law enforcement agencies, we propose the following principles: Do not be greedy for small profits and stay away from cryptocurrencies that deviate too much from the market price. If the selling price is far lower than the market price, it may be a dumping of black and gray industries. Avoid trading on anonymous platforms. The KYC mechanism has a high degree of binding force on OTC participants, which can reduce the possibility of users coming into contact with black u to a certain extent.

Pay attention to the risk audit of the source of virtual currency. Individual or institutional users with frequent transactions should conduct a daily analysis of the source of funds, and regularly conduct retrospective analysis and audits of business addresses. Pay attention to the background review of counterparties and their related counterparties, and avoid transactions with unfamiliar counterparties. In the transfer transaction scenario without the platform, it is necessary to conduct a review of the relationship risks of the first-party address and its associated addresses, and avoid lending your own on-chain address or platform account to others for unhealthy address usage, especially when collecting UST from unknown sources. Behavior may bring legal risks to oneself.
