If you receive dirty money during the withdrawal process, your bank account will be judicially frozen. Similarly, if you receive these black U's, your exchange account may also be judicially frozen by the public security authorities. Do you know which U's are black U's? Today, I will talk about the main sources of black U's that I know. You can also have some fun reading this without arguing about right or wrong.

1. Some exchanges are actually secretly cooperating with gambling platforms, allowing gamblers to exchange for USDT (which is U). However, these U's come from gambling, so they are all "black U's"! Some OTCs are still involved in this, unaware that the trouble they attract will ultimately lead to criminal offenses, constituting the crime of aiding and abetting.

2. Now gambling platforms are becoming more cunning. To evade detection, they have converted RMB chips into USDT. Want to gamble? First, deposit U! But do you know? These illicit funds will eventually be withdrawn to designated exchanges for cashing out. Once the gambling platform is investigated, all wallet addresses are marked, and the U flowing in and out becomes "black U". If the police follow the clues and find that your account on some An or Yi or other exchanges has transactions with these addresses, your exchange account will be classified as an involved account by the police, and sorry, involved account, frozen without negotiation!

3. After telecom fraudsters succeed, how do they launder their dirty money? The answer is to trade on exchanges, using your clean U to exchange for their dirty money. Once this exchange occurs, U transforms into black U! The fraudsters then manipulate the U a few more times, and when it returns to their hands, the money is laundered clean. These black U's circulate among those who have traded with them, and once you have transacted with a fraudster, your account will be monitored by the public security authorities, and a freeze notice will arrive!

So when trading cryptocurrencies, it is essential not only to avoid receiving dirty money but also to avoid receiving black U's.
