One thing I encountered was that I made a profit of more than 13,000 US dollars on the platform, but now I have to pay a tax of 10% and pay 1,300 US dollars to withdraw money. The total profit of the trading account is US$13.795, and 10% of the personal income tax is required to be paid, totaling US$1379.5. The validity period is December 11, and the trading account and funds will be permanently frozen in accordance with tax evasion and tax avoidance. Is this a scam?
