Call the police immediately, then collect the evidence, solidify all the evidence and write a statement of the case. Repair all your communication records, financial transactions and evidence. Because WeChat is a real-name authentication, you can find this person, but if it is someone else's WeChat, it is not easy to find.

You can try. You can find this person by phone number, bank account number and recorded IP of the trading platform. Also, keep in touch with him, don't startle him, tell him that you still want to win the money back, and you are raising money, and seduce him with benefits, and he will take the initiative to take the bait.

Don't push too hard on purpose. Also, if you can, investigate the trading platform you use. If there is something fishy, sue the platform together.

Ways to prevent being cheated:

1. Don't believe the information on the phone that you won the prize, there will be no pie in the sky for no reason. Don't be greedy and cheap, so that you won't be cheated.

2. Don't trust a phone call from a stranger saying that the phone is in arrears.

Don't trust the high commission on some chat software. Brushing a bill is also a bad thing. Generally, things with high commission are unrealistic.

4. Don't believe in the high-profit temptation of some intermediaries, and don't believe in the franchise projects that make a steady profit. For some uncertain things, you can ask your relatives and friends more.

5. Don't click on the link sent by strangers in your mobile phone. This is a new type of fraudulent information, which needs to be vigilant.
