The evolution of digital currency

1. The digital development of money is an inevitable trend in the use of money, and it is also the internal demand of money in the performance of monetary functions.

2.

Currency was widely used in the exchange between two kinds of commodities in ancient China. Its evolution process first changed from shell to metal. After the unification of the six countries, it became square hole money. Later, with the change of the times, there were more years and days on the money. Later, in order to facilitate transportation, paper money came into being. The times are changing, and the corresponding changes, digital currency also came into being

the development of digital currency has only begun in recent years. In the past 14 years, the people's Bank of China organized a team to study digital currency, considering a series of issues such as where the technology will be proced and circulated. They started to prepare a lot of materials in order to make more people willing to accept digital currency{ RRRRR}

money has a long history and different forms. Once it is implemented, our transaction will become more convenient, mobile phones have no signal, they can also pay, and its issuing cost is also very low. Although the digital currency is still being tested and improved, I believe that in the near future, the digital RMB will settle down

3. The emergence of digital currency was born under the expectation of pursuing a more perfect social and economic transaction mode and Global trade facilitation. It was discovered in the process of using science and technology to graally explore this need. The history of digital currency should start with the creation of bitcoin
the creation of digital currency
the origin of digital currency can be traced back to the 1990s, and electronic gold is one of the best forms. E-gold came out in 1999. It is based on real precious metals. Another consistent digital currency service is LR. Founded in 2006, it is an online payment company in Central America. It allows users to convert U.S. dollars or euros into LR, and only 1% of the transaction cost can be exchanged freely. This kind of two-way service is used by some people to launder money, so it is inevitably shut down by the U.S. government under the charge of money laundering
then, a person named Nakamoto published an article called "bitcoin: a peer-to-peer e-cash system" in the cryptography forum, which gave birth to bitcoin. Compared with legal currency, bitcoin does not have a centralized discoverer, but is generated by the calculation of network nodes, and is composed of a series of complex codes generated by computers. Anyone can dig, buy and sell bitcoin, and it is an anonymous transaction and cannot be tampered with. As a result, it is surrounded by geeks of popular technology, pursuers of complete liberalism and speculators
digital currency can be divided into open mining cryptocurrency and issuing cryptocurrency. Digital currency is defined as an Internet-based currency or exchange medium, which is different from physical currency. Digital currency can realize instantaneous transaction and ownership transfer without borders

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

5. Watch maintenance
(1) when wearing a watch, the sweat on the hand is corrosive to the watch case. The all steel case has better corrosion resistance because it is made of nickel chromium alloy, and the half steel case is made of copper. It is easy to corrode e to long-term contact with sweat. It is necessary to wipe away the sweat with a soft cloth or pad a plastic watch holder to prevent it from being eroded by sweat
(2) do not open the back cover of the watch at will to avoid st entering the movement and affecting the normal operation of the watch
(3) do not put the watch in the wardrobe with camphor pills to avoid the deterioration of the watch oil
(4) don't put the watch on the power amplifier, stereo or TV to avoid magnetization
(5) the watch that is not worn for a long time should be wound once a month, while the watch with automatic movement should swing back and forth for a few minutes or be worn on the wrist for a period of time to make it wind up automatically. So that the parts will not be at rest for a long time to ensure the operation performance of the meter machine
(6) if an ordinary mechanical watch is wet, dry cotton can be pressed on the watch and baked with 40 Watt electric bulb for 5 minutes, then the moisture in the watch will be evaporated completely. If the quartz electronic watch is damp, a few small pieces of calcium chloride can be taken and wrapped with gauze; Then open the cover of the electronic meter, put the wrapped calcium chloride and the electronic meter into a plastic bag or glass bottle without air leakage, and seal them. Generally, the moisture can be removed in about 3 hours to make the electronic meter return to normal. For the surface seriously affected by moisture, the time of absorbing moisture can be extended appropriately
(7) when the watch is received and the outer package is removed, the box used to protect the watch must be kept. These watch protection boxes can provide the safest protection for the watch when it is not fit to wear, so it is absolutely necessary to keep the box. It is suggested that when the watch is not worn on weekdays, we should form the habit of putting it in the box, which can greatly rece the risk of watch damage
(8) it's better not to wear the same watch every day, but to prepare several different watches for alternate use. In addition to enriching personal modeling, it can also avoid st and body dirt all concentrated on the same watch. For leather watch strap, more care should be taken to avoid frequent wear and tear caused by daily use. Even if the surface is new, the watch will look very old
(9) don't sleep with your watch on your wrist. If your watch is a luminous watch, it will bring adverse effects on your body. This is because the luminous material on the pointer and dial of the luminous watch is mainly a mixture of radium and zinc sulfide. The ray emitted by radium can stimulate the crystal of zinc sulfide to emit light. When you sleep, if you wear a watch, your body will be exposed to radium radiation for eight to nine hours, which is harmful to your body. Therefore, before going to bed, it is best to take down the luminous meter and put it on the table
(10) surface modification. After many lines have been scratched on the watch cover, you can first drop one or two drops of water on the watch cover, and then squeeze a little toothpaste to wipe it. Then you can remove the lines and make the watch cover look like new.

The minimum penalty for the crime of organizing and leading pyramid selling activities is criminal detention, and the maximum penalty is fixed-term imprisonment of more than five years. Generally, fixed-term imprisonment is not more than 20 years

Article 224-1 of the criminal law:

in the name of marketing goods, providing services and other business activities, organizations and leaders require participants to pay fees or purchase goods and services to obtain the qualification to join, and form a hierarchy according to a certain order, and directly or indirectly use the number of development personnel as the basis for remuneration or rebate, so as to lure and encourage the development of enterprises Those who force participants to continue to develop pyramid selling activities that others participate in, defraud property and disrupt economic and social order shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention and shall also be fined; If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not less than five years and shall also be fined

MLM in criminal law is different from direct selling. MLM in criminal law is a kind of criminal behavior, and the starting point of criminal behavior is low, which can more severely crack down on criminal behavior and prevent the occurrence of criminal behavior. And legal direct marketing is not MLM, so it will not be punished

Further information:

MLM originated in the United States in the late stage of World War II, took shape in Japan after World War II, and developed in China

In foreign countries, MLM and direct marketing have the same meaning, that is to say, there is only the concept of MLM in foreign countries. The main concept of foreign MLM is to use the word-of-mouth generated by customers' use of procts as the driving force, and let customers help dealers to promote procts and share part of the profits, that is, customer communication sales. This is different from the domestic concept of MLM

however, in China's criminal law, pyramid selling (Chinese style pyramid selling) is a false company, a fictitious proct, and everything is empty. It just lets you pull your head and draw a small commission from the membership fee or franchise fee

or control personal freedom, confiscate property, so that you can't contact the outside world, learn those MLM training materials every day, so that you can learn how to cheat people, and then make a list, telephone or letter invitation, showdown, follow-up, until you pay the membership fee or franchise fee in various ways

Chinese MLM is built on the basis of mind control, that is to say, you can organize MLM spontaneously after brainwashing through their MLM training; Others will control your personal freedom, confiscate everything, and force you to accept these lies

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

2

3. The evolution from local coinage to central coinage

4. From the weight of documents to Tongbao and Yuanbao

5. The evolution from metal currency to paper currency

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

knowledge development:

ordinary commemorative coin is RMB with specific theme and limited issue. Since the people's Bank of China issued the first set of ordinary commemorative coins in 1984, it has issued 63 sets of 75 ordinary commemorative coins, with a total circulation of about 850 million. The denominations range from 1 jiao, 1 yuan, 5 yuan, 10 yuan, 50 yuan and 100 yuan, which condenses the glorious achievements and major historical events of the people's Republic of China over 50 years into the square inch of commemorative coins

9. In 2009, Nakamoto Tsung invented bitcoin, which was the only digital currency at that time. Later, V God invented Ethereum, and then all kinds of counterfeit coins emerged one after another. So far, there are more than 1000 kinds of digital virtual currencies in the world. But with so many digital currencies, there are good and bad. Bitnet exchange has selected the most mainstream digital currency in the market to provide trading for investors.

10. On December 11, 2013, the Central Bank of Russia determined the currency symbol of ruble, the legal currency of Russia. Its shape is similar to a capital letter P, but the lower part of P has an extra horizontal. The currency symbol was voted by 280000 Russians, with a support rate of 61%

the website of the Central Bank of Russia announced on the same day that the central bank approved the currency symbol "₽" used to represent the ruble, It is in the form of a capital Cyrillic letter Р， But in Р The lower part of the letter P is supplemented by a horizontal line, so that a "=" is formed in the middle of the letter P. these two parallel lines symbolize the stable position of ruble. However, at the end of 2014, the ruble depreciated significantly.
