When you invest a small amount of money, they will let you withdraw a little profit. But once you invest a large amount of money, they will find excuses to say that there is a problem with your account and that the trading volume needs to be doubled. I reached the trading volume equivalent to the amount I invested, but when I contacted customer service to apply for withdrawal, they immediately closed my chat window. When I reopened the customer service interface, it was just a blue screen. Everyone must be vigilant against scam platforms and prevent more victims!!!
