As far as I know, choosing a bank to buy gold bars should consider the bank's reputation and brand, transaction cost and investment strategy. Large commercial banks such as Bank of China, Industrial and Commercial Bank of China and China Construction Bank may be worth buying gold bars. The above three brands have a good reputation and have a certain market share and experience in the field of physical gold investment. When buying gold bars, you need to pay attention to the fineness, weight, authenticity, storage and transportation of gold bars.
