Common means relatively few limits. Therefore, the common items should be inexpensive—for example, air. But just because it’s common doesn’t mean it lacks value. It simply signifies a lower price. Just because it’s almost free doesn’t mean it’s without merit. The sector a product belongs to affects the profitable connection between value and price. Daily necessities are inexpensive because they are common, but they hold significant value. If the imbalance between value and price exceeds the risks of an exchange opportunity, a profit is generated. If you capitalize on this opportunity and take a risk to purchase the imbalance, it is referred to as an investment. Opportunities always arise from imbalance. - 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"
