RMB appreciation, relatively speaking, the dollar will depreciate. What you have in your hand is dollars, of course, it will depreciate, and you can only buy a house of 80 square meters. If you have RMB in your hand, you can definitely buy a house of 120 square meters. Speculation in foreign exchange is to take advantage of this change in exchange rate to make a profit.

It is worth noting that the appreciation is only relative to foreign currency, that is to say, you can buy a house with 100 square meter in China before the appreciation, and you can still buy a house with 100 square meter in China after the appreciation.

There are many problems in the process of studying economics. So go to Baidu to post the economics bar. That's a good place.
