One graphic to understand why you receive dirty money when trading on exchanges? The entire process of scoring and money laundering is exposed:
Criminal groups recruit cardholders through card merchants → Remote control to money laundering dens → Use high-limit accounts to receive fraud funds → Purchase U-SDT at high prices from U merchants on exchanges to complete the money laundering → After U merchants receive the ill-gotten gains, they place orders to attract retail investors to sell → Retail investors' accounts are frozen due to receiving involved funds.
Throughout the entire chain, the criminal team injects dirty money into the exchange market through "buying U at high prices - selling U at a premium," ultimately leaving unsuspecting retail investors to bear the risk of account freezing, while the operators squander away after taking a 15% cut.
