Power, education, wealth, poverty and economic opportunities are all aspects of social progress and development, not the only ones. Through the course, we thoroughly examined these things through books and movies. A book such as "Republic" by Plato, "The Enemy of the People" by Henrik Isben, "The Laughing Sutra" by Mark Salzman, "Nickled and Dimed" by Barbara Ehrenreich. We confirmed that these functions are common in movies such as "Wag the Dog", "Moscow on the Hudson", "Manwate".
The role of currency exchange in contemporary monetary economics has obsession. In the 20th century, the state monopolized the issuance of money, continually damaged its use as a value store, and created a false idea that money is mainly defined as an exchange medium. Many people criticize bit coins as inappropriate money. Because its price is too unstable and not suitable as an exchange medium. But this puts the cart in front of the horse. Money is always developed step by step, the value is saved before the medium to exchange the character. Stanley Jevons, one of the ancestors of marginal economics, explained as follows.
The main job of money is to fulfill the role of exchange medium. Money does not support or fund the actual economic activity. Maintain consumer goods to provide food and funds. By playing a role as exchange medium, money only promotes the flow of goods and services between producers and consumers. Payment is an important utility of digital currency and requires more than the region's block chain technology to meet the most common payment needs. In payment, consumers usually purchase goods and services and pay in currency - this is the function of the digital currency. However, in order to complete the payment, not only the receipt of currency but also the products and services agreed first must be necessary. Therefore, the actual payment request is made only after both parties (consumer and seller) have resolved.
