If you receive dirty money during the withdrawal process, your bank account will be judicially frozen. Similarly, if you receive these black U, your exchange account may also be judicially frozen by the public security organs. Do you know which U is black U? Today, let's talk about the main sources of black U that I know. You can also take it as a fun exercise and avoid arguing about right or wrong.

1. Some exchanges are actually secretly cooperating with online gambling platforms, allowing gamblers to exchange for USDT (which is U). But these U come from gambling, so they are all 'black U'! Some OTCs are also trading in this, unaware that the trouble they cause ultimately leads to criminal offenses, constituting the crime of aiding and abetting.

2. Now online gambling platforms are becoming increasingly cunning. To evade detection, they convert RMB chips into USDT. Want to gamble? First recharge U! But do you know? These illegal funds will ultimately be withdrawn to designated exchanges for cashing out. Once the gambling platform is investigated, the wallet addresses will be marked, and the U that flows in and out will turn into 'black U'. If the police follow the clues and find that your account on a certain An or Yi or other exchanges has transactions with these addresses, then your exchange account will be deemed by the police as an involved account, sorry, involved account, freezing is non-negotiable!

3. After telecom fraudsters succeed, how do they launder dirty money? The answer is to trade on exchanges, using your clean U to exchange for their dirty money. Once exchanged, U also turns into black U! The fraudsters then circulate the U a few times, and the money returns to their hands clean. These black U then circulate among those who have traded with them, and once you have traded with a fraudster, your account will be monitored by the public security organs, and a freezing notice will come!

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