Buying U and selling U, the other party asks you to register a wallet, then after you receive U it gets stolen, can you report it to the authorities to recover it? Buying and selling U online and offline, you trade with the other party, and suddenly they ask you to register a new wallet, for example, asking you to register a certain Easy web3 wallet. They will tell you how to register, and the first transaction is always a small amount. You find out that it can indeed be withdrawn to the exchange, and then you proceed with a large transaction.

At this point, you need to be cautious. The wallet you registered will be multi-sig. After they transfer U to you, they say they have to leave, and then let you figure it out slowly. Their accomplices will directly transfer U from your wallet account, and your U that you just received not long ago gets stolen.

In this case, you need to do on-chain tracking and analysis. If this U ultimately reaches a centralized exchange, and the real-name information happens to belong to the other party or their friend, it can form a closed loop. If they sell this U to the next merchant, the next merchant can also identify the other party, which can also form a closed loop. Reporting to the authorities would mean the other party is guilty of fraud or theft, but if you have no evidence, and the other party transfers this U to some addresses used for laundering coins like Huiwang, Tornado, etc., it will be very difficult to recover it.
