Thinking too much. JC buys U, locks the selling U bank card, then checks this card for large transactions in the system, all frozen. Then extorts money one by one.

How do the police investigate cash-for-U and virtual currency fraud cases? What are their methods of investigation and analysis of the wallet addresses of guarantee platforms?

01. Online fraud: cash for U-branded products

In recent years' online fraud cases, the routine of online fraud customer service guiding victims to withdraw cash and then trade USDT (Tether) offline with U merchants has become a trend and has spread from the eastern region to the backward western regions.

One of the scams of exchanging cash for U: the fraud customer service induces the victim to invest in financial management → the fraud customer service provides the victim with a virtual currency recharge wallet address → the fraud customer service recommends several U merchants on WeChat to the victim → the victim and the U merchant agree on a time and place for an offline transaction → the victim hands over the cash to the U merchant → the U merchant first transfers 10U to the fraud wallet address for testing → the fraud customer service replies that the victim has received the test funds → the U merchant then transfers all the victim's cash equivalent to USDT to the fraud wallet address → the fraud customer service replies that the victim has successfully invested → a few days later, the victim's funds are drained and he realizes he has been scammed.
