There is no connection between RMB depreciation and gold preservation in a short time.
Therefore, "gold can preserve value" is a false proposition in a broad sense; Just in a narrow sense, because of the stability of gold's metallic properties, we say that gold is not easy to be damaged and chemical reactions are not easy to occur, and gold has monetary properties-it is not easy to obtain in a small amount, so it has the function of preserving value.
The rise and fall of gold price is cyclical, depending on demand, not RMB. In real life (RMB continues to depreciate, which is the inevitable product of rapid economic development for 30 years-abnormal growth-m2), if it is held for a long time (10 years and 20 years), it will have a certain value-preserving effect, but the additional storage cost will be high. However, from a longer-term perspective, gold is not a commodity with high investment value, because it is mined every year and is not actually consumed (it is not a consumable in itself, but actually stored in jewelry and so on). ).
If buying gold now is to gain profits through speculation (paper gold or gold futures), that is another concept, and we have to bear the risk of speculation.
