A young man said he could help me make money. Initially, I deposited US$3000 and made some profitable trades. I was able to successfully withdraw funds. Later, I increased my deposit to US$30,000 and continued to trade and make profits, earning approximately US$47,000. However, when I requested a withdrawal, it was unsuccessful. The customer service informed me that since my profits exceeded US$15,000, I needed to pay a 30% tax, which amounted to approximately US$13,000. I was given a deadline of 3 days to submit the payment, otherwise a 5% penalty would be deducted from my account daily. This withdrawal requirement was not mentioned anywhere on the platform. I was only informed about it when I requested the withdrawal, which is clearly fraudulent. I haven't paid the tax, and I don't know what to do now that 5% is being deducted from my account every day.
