First of all, you can check the official website of the Hong Kong Gold and Silver Exchange Society (HKCGM) or the website of the relevant regulatory authority to understand the supervision of precious metal trading platforms in Hong Kong. The Hong Kong Gold and Silver Exchange Society (HKBSE) is a regulatory body responsible for regulating precious metals trading platforms in Hong Kong to ensure that they comply with relevant regulations and standards. If a precious metals trading platform is not recognized or regulated by the agency, then it may not be a legitimate platform.
Secondly, you can judge the legitimacy of a precious metals trading platform by looking at its qualifications and certificates. Generally speaking, a legitimate precious metals trading platform should have relevant financial licenses and qualifications, such as Class AA or Class A licenses issued by the China Gold and Silver Exchange Society. These licenses and qualifications can prove that the precious metal trading platform has the qualifications and strength to engage in precious metal trading-related business.
Finally, it is advisable to do your full research and comparison before choosing a precious metals trading platform. You can refer to the opinions and recommendations of relevant regulators, industry associations or professional media to help you make more informed decisions. If you have any concerns or questions, you can consult a professional financial advisor or lawyer.
