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

1. Some exchanges are actually secretly cooperating with gambling platforms, allowing gamblers to exchange for USDT (which is U). But these U, because they come from gambling, are all 'black U'! Some OTC traders are still engaging in this, unknowingly getting involved in criminal trouble, constituting a crime of assisting.

2. Now gambling platforms are becoming increasingly cunning. In order to evade investigation, they have exchanged RMB chips for USDT. Want to gamble? First recharge U! But do you know? These ill-gotten gains will ultimately be withdrawn to designated exchanges for cashing out.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 a certain safe exchange or other exchanges has transactions with these addresses, your exchange account will be identified as an involved account by the police, and sorry, involved accounts will be frozen without discussion!

3. After telecom fraudsters make a profit, how do they launder dirty money? The answer is to trade on exchanges, exchanging your clean U for their dirty money. This exchange turns U into black U! The fraudsters then shuffle the U a few times, and when it returns to them, the money is laundered clean. And these black U circulate among those who have traded with them, and you, once you have traded with a fraudster, will have your account monitored by the public security authorities, and a freeze notice will arrive!

So when trading coins, not only should you avoid receiving dirty money, but also avoid receiving black U.
