A friend just lost more than 70,000 U. Here’s what happened: the transfer was transferred to the wrong contract address, and then she thought about contacting the official community. She contacted more than a dozen people, and one of them replied (she was not on guard, but she should be alert at this time). She was told to wait patiently for two hours, and he would help and ask the team. (At this time, the scammer is already inducing your time cost), and then he said that a technical staff from the team would be pushed in eight hours (secondary preparation increases sunk costs). Then today, they added that a new address is needed. And the private key needs to be provided. My friend thought about the new address and didn’t take it seriously. But the scammer transferred all the coins in other addresses through a new address. Be careful in the currency circle! Remember to always be on guard.
