Money is the most widely used medium of exchange worldwide, serving as a way to buy essential goods needed for life or to store wealth. Since the country guarantees the stability of fiat currency, it becomes possible to exchange ‘things for money’ instead of ‘things for goods,’ unless the country goes bankrupt. However, this amount of money cannot be increased indefinitely. When there is too much money in circulation, its value drops below the price of goods, causing those who hold wealth in money to lose that wealth. The key point is that money is limited in the market. Due to this limitation, money gains value. The government regulates this money supply through the ‘interest rate.’ Raising the interest rate reduces the money supply, while lowering it increases the supply. This helps control prices. Therefore, understanding the interest rate is crucial for managing and valuing wealth, making it essential to know the interest rate above all else in life. - Joseph’s “just my thoughts”
History professor Yuval Noah Harari said, "The most distinguishing feature between humans and other animals is the ability to believe not exist imagination." If you eat a banana exchanged with a bill from the chimpanzee, then the chimpanzee must be angry with you. The bill is just a thing to believe non-existent imagination each other in the human world, it's never important and meaningful for the chimpanzee. Unless the belief is to exchange the value, the money is just paper. This belief makes our social community. - Joseph's "just my thoughts"
