During the pandemic, my friend recommended me Huanengfx with code 20137. After installation, I deposited some fund. At that time, the withdrawal was available. Later, I won the prize and transferred the fund to Huanengfx . But the withdrawal became unavailable. Huanengfx claimed that only super VIP could withdraw fund by large amount, asking for 100 thousand. When I wanted to call the police, Huanengfx threatened that no authority can regulate forex business since it is a grey zone. Take heed on it.
