Existing economics teaches us that mankind invented the monetary system because barter was inconvenient. Despite having a monetary system, people still felt that even currency issued by it was inconvenient; therefore, economists explain that they created the current credit economy system. However, evidence found by anthropologists contradicts that explanation. In other words, it is argued that the credit transaction system existed before the monetary system, and then the credit system became distrusted for some reason. As a result, the monetary system was created and eventually replaced. Cryptocurrency today is a mathematical algorithm that makes it impossible to forge or alter transaction records. This happened because we don’t trust humans, and in ancient times, there was a more advanced credit transaction system. Don’t be fooled into thinking that the present is more advanced than the past. - Joseph’s “just my thoughts”
In the USA, even in one country, the time difference between the west and the east is 3 hours. People thought that time was a natural thing. But it is not. It's very political. The time that man lives in a unit of minutes is too short. However, since the invention of the steam locomotive, the appearance of faster vehicles made crazy changes to the concept of time. The shift in distance made people realize what time was. Sandford Fleming, an engineer and inventor, asked to unify the time difference caused by long-distance transportation, but people rejected his request. If the boarding time were not fixed, the railroad would be useless. The history of the 24-hour clock was made only about 140 years ago. Even with the invention of high technology, if nothing is consensus, nothing benefits. - Joseph's "just my thoughts"
