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 business, capital means business funds. A successful entrepreneur often says, "I started my business without any capital". It's partly true, but it's a lie. The entrepreneur just said that capital means only cash. However, all kinds of businesses need to be fundamentally business funds in any even not cash. The entrepreneur didn't count the founder's labor cost. No inputs, no outcomes. The uncounted labor costs are called "alternative costs" or "opportunity costs". This comes from comparative advantage. If the entrepreneur doesn't accept the uncounted labor cost as a debt, the entrepreneur is equivalent to losing the profit due to opportunity costs. Please always remember this. There is no free lunch in this world. - Joseph’s “just my thoughts”
