Foreign exchange speculation is unreliable and deceptive. Foreign exchange speculation is generally pulled into the WeChat group, which is called "foreign exchange arbitrage". There are instructors "shouting orders" in the group. From time to time, people have their own "profit screenshots", and there are all kinds of words thanking teachers for making money. Then the victim added the owner's WeChat and registered the mobile app account under its guidance. Then the victim will recharge the platform with a small amount of money according to the guidance of the "teacher" and prepare to test the water. Then the platform will show that there is an increase in the amount, indicating that the liar will seize the opportunity to let the victim continue to invest. It was not until the swindler took out all the money in the account that the victim realized that he had been cheated. At this time, it was too late and he could only choose to call the police.
