Physical gold trading includes transactions such as gold bars, gold coins and gold ornaments, with holding gold as an investment. It is certain that the investment is high, and the actual rate of return is the same as other methods, but the amount involved will be low (because the invested funds will not play a leverage effect), and it can only be profitable when the gold price rises. Generally, the buying and selling prices of decorative gold are quite different, so it should not be regarded as investment. Gold bars and coins are the best choice for real gold investment because they do not involve other costs. However, it should be noted that holding gold does not generate interest income.
