The evolution of virtual currency

1.

There are four stages of currency experience:

1, accidental barter

accidental barter refers to the human's initial commodity exchange at the end of the primitive society. It occurs under the extremely accidental situation that both sides of the tribe have surplus procts. At this time, commodity exchange has great contingency, so it is called accidental barter

With the development of proctivity and social division of labor, the frequency of barter has increased, and the types of commodities participating in the exchange have also increased. At this time, commodity exchange is the expanded barter

When the scope of the transaction is expanded and the variety is increased, the exchange of things is very difficult. Even if it can be established, it will cost too much manpower, material resources and time. The low exchange efficiency has seriously hindered the development of commodity proction

Therefore, the general equivalent is a special commodity separated from the commodity world as a unified expression of the value of all other commodities. This is the proct of the development of commodity proction and exchange to a certain stage

The general equivalent is fixed on gold and silver.

the commodity used as the general equivalent is different in different regions and periods, which is not concive to the development of commodity economy objectively. Because gold and silver are rare and easy to be separated and stored, they are graally fixed as general equivalents, and money comes into being

extended data:

money is a fixed commodity separated from commodities and serves as a general equivalent

In essence, money is a contract between the owner and the market about the right of exchange, which is essentially an agreement between the owners. I give what I have to the market in exchange for what I need. Money is the agreement in this process, which reflects the economic cooperation between indivials and society

the nature of money contract determines that money can have different forms, such as general equivalent, precious metal money, paper money, electronic money and so on. It can be used as a medium of transaction, storage value, deferred payment standard and accounting unit

According to issuers, money can be divided into public money (fiat money), private money and regional money (community money). Generally speaking, public money is issued by the government. When it exists, it is generally dominant. Private money and regional currency are issued by non-governmental organizations

According to the classification of materials, people used different goods as money in different historical periods. It can be divided into shell, bead, stick, metal currency (see commodity currency), paper currency and digital currency. In terms of nature, it can be divided into real money and virtual money

The essence of money is the general equivalent. In the process of the continuous development and evolution of human history, it has gone through the stage of physical money, the stage of substitute money, and then entered the stage of credit money. In primitive society, people exchanged livestock, salt, shells and other hard to get goods as general equivalents

in the long history, the emergence of metal currency makes the economic life achieve unprecedented prosperity. However, e to the inconvenience of carrying metal money, paper money became the mainstream form of money. With the rapid development of modern information technology, e-money has come into our life

if the evolution process from physical money to value symbol paper money is the first qualitative leap in the history of money development, then the evolution process from paper money to electronic money is the second qualitative leap in the history of money development

from the perspective of money form, physical money itself is a commodity in addition to performing monetary functions; Paper money is a symbolic tool of value for commodity exchange and a credit currency; Electronic currency is the proct of highly developed Internet economy and continuous progress of bank payment and settlement technology. It not only has the function of traditional currency, but also can continuously improve digital currency

At the same time, the virtual money market based on electronic information is also booming. By the end of 2014, the number of Internet users in China had reached 632 million, including 517 million registered users in the online game market and 114.48 billion yuan of sales revenue, an actual increase of 37.7% over the previous year

a huge virtual space based on the Internet has been formally formed. As a kind of virtual currency with intrinsic value, convenient online trading behavior, low transaction cost, and service providers' issuance, it emerges as the times require

first of all, from the functional analysis. Virtual currency is a kind of transaction medium in the Internet virtual space, which has the function of value scale, but the value scale of virtual currency is different from that of legal currency

using virtual currency to purchase virtual procts and services can only be within the scope specified and allowed by the issuer of virtual currency (Internet operator), and the size of this scope depends on the number of virtual procts and services. If the virtual procts and services provided by the website are large enough, the scope of virtual currency will be large

the currency value of virtual currency depends on the pricing of virtual currency by issuers. When no currency can communicate between virtual cyberspace and reality, the pricing of procts and services is still based on real RMB. That is to say, when issuers of virtual currency price their own virtual currency, they should first convert the price of virtual currency based on RMB

4. Six major evolutions of Chinese ancient currency

China is one of the earliest countries in the world to use currency, with a history of 5000 years. In the process of its formation and development, ancient Chinese currency has undergone six major evolutions:

first, the evolution from natural currency to artificial currency

in Chinese characters, most of the characters related to value have changed from "Bei". From this we can see that Bei is the earliest currency in China

with the rapid development of commodity exchange, the demand for money is increasing, and seashells have been unable to meet people's needs. People began to imitate seashells with copper. The appearance of copper shell is an important evolution from natural currency to artificial currency in ancient Chinese currency history

with the extensive use of artificial coinage, seashells, as a natural currency, graally withdrew from China's currency stage< From the appearance of Tongbei in the Shang Dynasty to the Warring States period, China's currency graally formed four systems characterized by the domination of the feudal lords, namely, shovel coin, Dao coin, ring coin and Chu coin (yuan Jin and Yi Bi Qian)< After Qin unified China, the first emperor of Qin promulgated the earliest currency law of China in 210 BC, which stipulated that half Liang coins with round square holes could be used in the whole country

the circulation of Qin banliang coins with round square holes in the whole country has ended the disordered state of different shapes and great weight differences of ancient Chinese coins, which is a significant evolution from disordered shape to standard shape in the history of ancient Chinese coins. The shape of this round square hole determined by the Qin banliang coins continued until the early Republic of China< Third, the evolution from local coinage to central coinage. According to the records of Shi Huo Zhi in the history of the Han Dynasty, Liu Bang allowed the people to make coins privately after the founding of the Han Dynasty. The gentry, the rich businessmen and the local forces took advantage of the opportunity to make money. In the reign of Emperor Wen, "Dr. Deng Tong also made money for the king."

in the fourth year of Yuanding (1115 years ago), Emperor Wu of the Han Dynasty took back the minting right of the prefecture and minted five baht coins by the central government. From then on, it was determined that the central government should be responsible for the unified management of coin casting and issue, which was a significant evolution from local coin to central coin in the history of ancient Chinese currency

since then, the central government has been directly in charge of the coinage. The return of the minting right to the central government played an important role in stabilizing the political situation and economic development of the dynasties< (4) the evolution from the weight of documents to Tongbao and Yuanbao (24 baht is one or two)<

in the fourth year of Wude (621), Emperor Gaozu of Tang Dynasty, Li Yuan was determined to reform the currency system, abolish ancient coins of different weights, and cast "Kaiyuan Tongbao" coins with the meaning of "opening up a new era". Kaiyuan Tongbao is a change from the weight of documents to Tongbao and Yuanbao in ancient China

Kaiyuan Tongbao coin is the earliest Tongbao coin in China. Since then, copper coins in China no longer use money to mark the weight, but use Tongbao and Yuanbao. It has been used until the "Tongbao of the Republic of China" after the 1911 Revolution< In the Northern Song Dynasty, e to the shortage of copper materials, the government made a large number of iron coins in some areas to make up for the shortage of copper coins. According to the records of the history of Song Dynasty, the cast iron coins in Sichuan at that time always weighed 25 Jin and 8 Liang. To buy a piece of silk in Sichuan, you have to pay 130 Jin of iron. Iron money is so cumbersome and inconvenient that paper money jiaozi came into being in Sichuan. The appearance of Jiaozi is an important evolution from metal currency to paper currency in ancient Chinese currency history

Jiaozi is not only the earliest paper currency in China, but also the earliest paper currency in the world< In the late Qing Dynasty, with the graal introction of foreign advanced science and technology, Guangxu began to buy coin making machines abroad to make silver and copper coins. Later, Guangdong began to use machine-made holes when ten copper. Because of the huge profits of the manufacturers, many provinces followed suit

the emergence of mechanism currency in the late Qing Dynasty is an important evolution from manual coinage to mechanism currency in the history of ancient Chinese currency.

5.

The form of money has gone through two important stages: metal money and credit money. In the future, electronic money will probably become the main form of money

money comes from the need of commodity exchange and is the proct of the development of the internal contradictions of commodity economy to a certain stage. Its function is to provide the medium of exchange or means of payment for commodity exchange

Because of this, the early currency took the form of commodity, which was a special commodity separated from the general commodity and served as the general equivalent. Marx has a famous saying that "gold and silver are not money naturally, but money is gold and silver naturally."

the initial physical currency, such as the shell used in the process of exchange; Later, shell and other physical currency were not easy to exchange, so they evolved into metal currency, such as iron. This was base metal at first, then deepened into silver, and then gold

However, there are great inconveniences in the custody and use of physical currency, and with the expansion of transactions, there is not so much gold and silver in the world to act as currency, so many countries began to issue paper money. At first, the paper money was linked to gold and silver, and later it was not held by gold and silver. Therefore, from physical currency to paper money is a change from real value to credit mode

extended data:

money can be formally divided into physical money and formal money according to the commodity value of money. Physical money itself is a kind of special commodity, including the amount of value, such as sheep, precious metals, etc; The formal currency itself has no value, its value is contractual, only contractual value

the two forms are different, but they are unified in essence, that is, they are both agreed as the medium of exchange, and both have contractual value. The purchasing power of money depends on the contract value of money, but the purchasing power of physical money is also affected by its own commodity value. Generally, the commodity value of physical money is less than its contract value as money

The essence of money is generally regarded as a general equivalent

the following is the debt theory about the essence of money in the past, that is, they think that money is a kind of creditor's right of the holder to the issuer, which has obvious flaws, and can not answer the basic questions such as why the issuer borrows rights and how to repay them

6.

In the process of formation and development of ancient Chinese currency, it has experienced five extremely significant evolutions:

1, the evolution from natural currency to artificial currency

Shell is the earliest currency in China, and it was used as currency in Shang Dynasty. In Chinese characters, most of the characters related to value are related to "Bei"

2

from the appearance of copper coins in Shang Dynasty to the Warring States period, there were many shapes of Chinese currency. During the Warring States period, not only all countries made their own money, but also all regions in a feudal state made their own money

3. The evolution from local coinage to central coinage

in the early Han Dynasty, the prefectures were allowed to cast money freely. According to the records of Shi Huo Zhi in the history of Han Dynasty, Emperor Wen "removed the order of stealing and casting money, and made the people cast money freely", so "stealing and casting rose like clouds". This not only caused the currency confusion, but also made the rich merchants manipulate the coinage right, making the rich ratio the emperor

4. From the weight of documents to Tongbao and Yuanbao

The weight of coins, such as "half Liang", "five baht" and so on (twenty-four baht is one or two), is usually clearly indicated in the inscriptions

5. The evolution from metal currency to paper currency

In the Northern Song Dynasty, with the development of exchange, the amount of money in circulation increased. In the Northern Song Dynasty, Taizong coined 800000 yuan a year, and then graally increased

According to the extended data, the foreign natural currency includes agate shells, dolphin teeth, tea, tobacco, pine resin, wool, salt, etc. In modern society, in a specific environment, people may still use natural forms of goods as money. For example, cigarettes were used as money in the American POW camp in World War II

From the spring and Autumn period to the Warring States period, China has established four monetary systems: cloth coin, knife goods, ant nose money and ring money. Later, it went through the Qin, Tang, Han, Wei, Jin, southern and Northern Dynasties, until December 1, 1948, the people's Bank of China was established and issued the first set of RMB

7. Money is the proct of commodity exchange. At the end of primitive society, the earliest currency was physical currency. Generally speaking, nomadic people used livestock and animal skins to realize their monetary functions, while agricultural people used grain, cloth, agricultural tools, pottery, seashells, pearls and jade as the earliest physical currency. According to archaeological excavation, a large number of pottery pots were unearthed from the late Neolithic sites such as Banpo as sacrificial objects; A large number of pig heads and mandibles were buried in Dawenkou Culture, which shows that pigs and pottery played the role of monetary wealth in the late primitive society. However, as we all know, the widely circulated ancient physical currency was "Bei". Because as physical currency, cattle, sheep, pigs and other livestock can not be separated, grains will rot, pearls and jade are too few, and knives and shovels are too heavy, so the final focus is on the seashells. Seashells can be used as necklaces. They are valuable and easy to carry and count. Therefore, they are selected as the main currency in long-term commodity exchange. In the archaeological excavation, a large number of natural shellfish were unearthed from the sites of Xia Dynasty and Shang Dynasty, and they were used as physical currency until the spring and Autumn period. Therefore, most of the Chinese characters related to wealth and value are related to "Bei". Such as: expensive, capital, greed, poverty, wealth, purchase, etc
China is one of the earliest countries in the world to use currency, with a history of 5000 years. In the process of the formation and development of ancient Chinese currency, it has experienced six major evolutions:
first, the evolution from natural currency to artificial currency
in Chinese characters, most of the characters related to value are from "Bei". From this we can see that Bei is the earliest currency in China
with the rapid development of commodity exchange and the increasing demand for money, seashells have been unable to meet people's needs, and people began to imitate seashells with copper.

The shape of this round square hole determined by the Qin banliang coins continued until the early Republic of China< Third, the evolution from the local coinage to the central coinage
according to the records of Shi Huo Zhi in Hanshu, after the founding of the Han Dynasty, Liu Bang allowed the people to make coins privately, and the gentry, rich merchants and local forces took the opportunity to make profits by casting evil money. In the reign of Emperor Wen, "Dr. Deng Tong also made money for the king."
in the fourth year of Yuanding (115 BC), Emperor Wu of the Han Dynasty took back the minting right of the prefecture and minted five baht coins by the central government.

Later, Guangdong began to use machine-made holes when ten copper. Because of the huge profits of the manufacturers, many provinces followed suit
the emergence of mechanism currency in the late Qing Dynasty is a significant evolution from manual coinage to mechanism currency in the history of ancient Chinese currency
since then, not only has the technology of casting coins changed greatly, but also the round square hole coins that have been circulating for more than 2000 years have been put to death.

8. China is one of the earliest countries in the world to use currency, with a history of 5000 years. In the process of formation and development, ancient Chinese currency has experienced five major evolutions:

1. The evolution from natural currency to artificial currency. Shell is the earliest currency in China, which was used in Shang Dynasty. In Chinese characters, most of the characters related to value begin with "Bei". With the development of commodity exchange, more and more money was needed, and seashells could not meet people's needs. In Shang Dynasty, people began to imitate seashells with copper. The appearance of copper coin is an important evolution from natural currency to artificial currency in ancient Chinese currency history. With the extensive use of artificial coins, seashells, as a natural currency, graally withdrew from China's currency stage

2. From the appearance of Shang Dynasty copper coins to the Warring States period, there were many shapes of Chinese coins. During the Warring States period, not only all countries made their own money, but also all regions in a feudal state made their own money. It is famous for the shovel coin of Zhao, Dao coin of Qi, round square hole coin of Qin and ant nose coin of Chu. After Qin unified China, the first emperor of Qin promulgated the earliest currency law of China in 210 BC, which stipulated that half Liang coins with round square holes of Qin state could be used throughout the country. The unification of currency ended the disordered state of different shapes and great weight disparity of ancient Chinese currency, and it was a significant evolution from disordered shape to standard shape in the history of ancient Chinese currency. The shape of this round square hole determined by the Qin banliang coins continued until the early Republic of China< 3. The evolution from local coinage to central coinage. In the early Han Dynasty, the prefectures were allowed to cast money freely. According to the records of Shi Huo Zhi in the book of Han Dynasty, when Emperor Wen "got rid of the order of stealing and casting money, he made the people cast money freely", so "stealing and casting rose like clouds". This not only caused the currency confusion, but also made the rich merchants manipulate the coinage right, making the rich ratio the emperor. In 113 BC, Emperor Wu of the Han Dynasty regained the minting right of the prefecture, and the central government unified the minting of wuzhu coin, which became the only legal currency at that time. From then on, it was determined that the central government should be responsible for the unified management of coin casting and issue, which was a significant evolution from local coin to central coin in the history of ancient Chinese currency. Since then, the central government has been in charge of the coinage. The return of the minting right to the central government played an important role in stabilizing the political situation and economic development of the dynasties

4. From the weight of documents to Tongbao and Yuanbao. Since the Qin and Han Dynasties, coins are usually clearly marked with the weight of money, such as "half Liang", "five baht" and so on (24 baht is one or two). In 621, Li Yuan was determined to reform the currency system, abolish the ancient coins of different weights, and cast "Kaiyuan Tongbao" coins with the meaning of "opening up a new era"“ "Kaiyuan Tongbao" is a change from the weight of documents to Tongbao and Yuanbao in ancient China“ Kaiyuan Tongbao money is the earliest Tongbao money in China. Since then, copper coins in China no longer use money to mark the weight, but use Tongbao and Yuanbao. It has been used until the "Tongbao of the Republic of China" after the 1911 Revolution

5. The evolution from metal currency to paper currency. In the Northern Song Dynasty, with the development of exchange, the amount of money in circulation increased. During the reign of Emperor Taizong of the Northern Song Dynasty, the annual coinage was 800000 yuan, and then graally increased. In order to make up for the shortage of copper coins, the government cast a large number of iron coins in some areas. According to the records of the history of Song Dynasty, the cast iron coins in Sichuan at that time always weighed 25 Jin and 8 Liang. To buy a piece of silk in Sichuan, you have to pay 130 Jin of iron. Iron money is so cumbersome and inconvenient that the paper money "Jiaozi" created and printed in the Northern Song Dynasty came into being in Sichuan. During the reign of emperor Zhenzong of the Song Dynasty, with the permission of the government, it was jointly operated by 16 wealthy families in Cheng“ The appearance of "Jiaozi" is an important evolution from metal currency to paper currency in ancient Chinese currency history“ Jiaozi is not only the earliest paper currency in China, but also the earliest paper currency in the world.

9. China is one of the earliest countries in the world to use currency, with a history of 5000 years.

It has been used until the "Tongbao of the Republic of China" after the 1911 Revolution< In the Northern Song Dynasty, e to the shortage of copper, the government made a lot of iron coins in some areas to make up for the shortage of copper coins. According to the records of the history of Song Dynasty, the cast iron coins in Sichuan at that time always weighed 25 Jin and 8 Liang. To buy a piece of silk in Sichuan, you have to pay 130 Jin of iron. Iron money is so cumbersome and inconvenient that paper money jiaozi came into being in Sichuan. The appearance of Jiaozi is an important evolution from metal currency to paper currency in ancient Chinese currency history. Jiaozi is not only the earliest banknote in China, but also the earliest banknote in the world< Sixth, the evolution from hand coining to machine-made paper money: in the late Qing Dynasty, with the graal introction of foreign advanced science and technology, foreign minting machines were purchased to make silver and copper coins ring the reign of Guangxu. Later, Guangdong began to use machine-made holes when ten copper. Because of the huge profits of the manufacturers, many provinces followed suit. The emergence of mechanism currency in the late Qing Dynasty is the evolution from manual coinage to mechanism currency.

10. "Money" is the common name of currency in China. It is a special commodity that acts as an equivalent in the exchange of goods and services in a specific country or economy, or to repay debts. Why is money called money“ What is the origin of the word "money"? It turns out that in the long development of commodity exchange, the commodities that play the role of general equivalent do not use gold at the beginning, but use livestock first. However, the size, weight, sex, health and disease of livestock are different. In addition, it can not be separated and is not easy to carry and keep, so it is replaced by grain and silk. However, as a general equivalent, there will also be speculation that "Wengu asks for profits and makes thin silk for the market". Because of their different quality, the price trend will cause trouble. As time goes by, people trade goods with weapons, proction tools and other objects as general equivalents. In ancient China, there was a kind of agricultural tool, which was called "Qian" at that time. At first, Qian was a bronze casting tool for farming. Because farmers have to rely on this tool to engage in proction and labor, and "money" is easier to exchange than land and other goods. Because it was used as a medium of exchange for a long time, it graally evolved into currency, and the name "money" has been used. In the Han Dynasty, the feudal and superstitious rulers, out of the desire to accumulate wealth, changed "money" to "spring", and "spring" became the borrowing of "money". It's more vivid to use "spring" to call money. No wonder some people vividly compare that "spring" comes together from all directions and flows to all directions. Therefore, until modern times, the borrowed word "Quan" is still used. For example, coin collectors always use "Quanyou" as a reference.
