Knowledge points related to virtual currency

what is digital currency

digital currency can be used to describe all electronic currencies, including virtual currency and cryptocurrency. Digital currency is a kind of electronic currency without any physical form. Because of its functions and inherent attributes, it is the same as the standard illegal fixed currency, and can also be referred to as the network version of cash. Digital currency is invisible. People need to use and hold it through devices that can be connected to a specific network

extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

1、 Common analysis of virtual currency (1) bitcoin solution is designed and created by Japanese programmer Nakamoto (alias) in 2009, and it is the most successful and controversial network currency at present. Bitcoin scheme is based on P2P network architecture, which has been operating in the world, and can be used for all kinds of virtual and real goods and services transactions

(1) from the analysis of the impact on the amount of money, although it is difficult to analyze the extent to which the network currency scheme creates money in the case of lack of information

(2) from the analysis of the impact on the speed of money circulation, the use of cash and money statistics, the impact of the technological innovation brought by the network currency scheme on the speed of money circulation is not clear

as an Internet instry, it largely depends on the number of active internet currency scheme users. If the network currency is widely accepted, it will have a substitution effect on the real currency of the central bank, thus recing the use of cash in transactions
in this case, the scale of the central bank's balance sheet will be reced, and its ability to influence short-term interest rates will also be weakened. The central bank will need to fight against risks through ways such as setting minimum reserves for cyber currencies. Substitution effect will aggravate the difficulty of monetary statistics and affect the relationship between monetary statistics and inflation, which is not concive to the realization of long-term price stability. In addition, the issuance of network currency outside the central bank and the expansion of virtual credit will have an impact on the central bank's interest rate decision in the economy and weaken the central bank's monetary control

(3) from the analysis of the interaction between network currency and real economy, network currency can act as a real commodity trading medium and have an impact on real GDP

(1) money supply and other actions taken by currency issuers. For example: to achieve a fixed or semi fixed exchange rate by intervening in the market

(3) the virtual community with clear and transparent policies and advanced security measures is easier to boost confidence and the currency is stronger

(4) the reputation of network currency issuers in fulfilling their commitments. There is no "lender of last resort" in the virtual community, and the trust gained by the issuer is crucial to the exchange rate of internet currency

(5)
speculation on the future value of Internet money and cyber attacks on virtual communities. Due to the immaturity of the system, low trading, speculative activities and network attacks, the two-way network currency scheme is inherently unstable
qualitative. At present, the trading volume of these network currencies is small and the correlation with the real economy is low, so the stability of the financial system will not be affected. However, if Internet money becomes a substitute for traditional money in the future, it will bring instability to the financial system and even distort the relative prices of goods and services. The impact of network currency system on the financial system largely depends on the number of active users and the number of merchants who are willing to accept virtual currency for real transactions. In addition, virtual currency has only exchange value and no use value. Generally, network currency is not based on assets with intrinsic value and is not supported by central bank credit. At present, these network monetary systems are not allowed to lend
or borrow funds, so it can not pose a threat to the stability of the financial system, but we should pay close attention to its development. If there is any change in the future, it will undoubtedly have an impact on the financial system

in a specific virtual community, virtual currency payment activities have evolved into a "real" payment system, facing typical risks related to the payment system: credit risk, liquidity risk, operational risk and legal risk. The nature, scale and ration of these risks are largely determined by the design of the system or the degree of lack of liquidity, so it is difficult for the network virtual currency scheme to avoid or control these risks. According to the core principles of payment system (CP) issued by the bank for International Settlements (BIS), the network virtual currency scheme does not conform to most of the contents of CP, and does not belong to the systemically important payment system. Therefore, it will not cause
or transmit shocks in the global financial system. At present, there is no systematic risk in the network currency system outside these virtual communities

2. Lack of corresponding supervision and protection mechanism

in the real economy, the central bank plays the role of lender of last resort and has no default risk, so it can take actions in the case of payment crisis or unpredictable liquidity shortage to avoid chain reaction. However, in the network virtual currency scheme
it is impossible to use network currency as settlement asset. Because network currency simply depends on the credibility of the issuer, it can not be widely accepted as a means of payment, so network currency can not be regarded as a safe currency. In addition, commercial banks are required to accept prudential supervision, which reces the possibility of default, and the security of money in commercial bank accounts is higher than that of network currency. A fundamental risk of network currency is that the settlement institution of network currency scheme is not subject to any supervision, no institution is responsible for its behavior, and there is no investor / depositor protection mechanism, which causes the user to bear all the risks

virtual currency is always inferior to real currency< br />

The instrialization of virtual money will form a virtual money market. If the emergence of the stock market is the proct of the combination of instrial capital and financial capital, then virtual currency will be the proct of the combination of service capital and financial capital. Modern service instry, especially personalized modern information service instry, will become the instrial foundation of personalized virtual currency. Personalized virtual money market is different from stock market and derivative financial instrument market. The latter is established for the needs of instrialization, which is also reflected in meeting the needs of the so-called modern service instry; The instrial foundation of the former is closely related to the demand of informatization. The future of the tertiary instry is different from the service instry, its development direction is the post-modern service instry, that is, the experience instry, that is, more personalized instry to meet the development needs of spirit, culture and entertainment. The stock market will make more use of information to guide the rational investment of instry and service instry, while the personalized virtual money market will make more use of information to guide the perceptual consumption of experience instry
in this context, the instrial basis and role of virtual currency will reflect its special side

with information function
the biggest difference between personalized virtual currency and stock market is not only the integrated pricing function of reference point, but also the distributed pricing function of reference point. This process is not completed in the virtual money market, but in the development of personalized modern services. For example, in the process of indivial auction, the bargaining process combined with frame should include not only a process of utility exchange leading to value unification, but also a process of value realization leading to value diversification. This means that virtual currency must be combined with the development of personalized information service instry. Although the stock also has certain information function, but this kind of information is subordinate, it is instry centered. In the future, virtual currency may have three functions: currency, stock and information card. On the one hand, it can be used as the base currency (or exchanged with the base currency) to obtain liquidity; On the one hand, it can have value-added function; The most important thing is that additional information can be added. And this kind of information is just a kind of interface information to be completed, which needs to continue to realize its value in the service instry
cultural value positioning
in the future personalized virtual currency trading market, price level information similar to stock index will also be formed. But different from the stock index, the price index of personalized virtual currency will not reflect the investment value-added information, but the entertainment value, cultural value, spiritual value, free value and personality value similar to cool value. For example, the game index may reflect not the investment value, but the degree of indivial freedom value. For another example, in the super girl vote, it is reflected in the popularity index rather than the professional index. If it does not refer to SMS voting, but a personalized IC card with integrated currency and derivative financial instruments functions, such as corn card and fans card, the value of the card will fluctuate with the fashion information, reflecting the freedom of indivial choice. Once combined with the development of personalized service instry, a benign interaction mechanism is formed
upgrading traditional instries
with the development of game instrialization and instrial Gamification, indivial freedom has been comprehensively developed, that is, personalized self realization, which will become the ultimate goal of instrial upgrading. Traditional instries, including proct manufacturing and service instries, will take the satisfaction of spiritual and cultural values as the pursuit of added value of procts and services. In the background of the development of this instry, the role of personalized information service instry in driving traditional instries may be realized through the guidance of personalized virtual money market. That is to say, after the procts and services of traditional instries have reached the optimal homogeneity, they will eventually find out under the guidance of the information market that those things that are cool enough will sell well, and those that are not cool enough will not sell. In the future, the instry development will not only need the guidance of GNP stock index, but also need the guidance of GNH cool value index. The paper points out that GNC (National cool value) Japan is moving towards a mode of instrial development, thus following the Meiji Restoration, it is moving towards the road of modern instrial development. The United States and South Korea are also ahead in this regard. China is facing the choice of the second modernization. Many small things like virtual currency actually contain significant information< After October 30, 2008, indivials in China have to pay personal income tax on the income from purchasing virtual currency of players through the Internet and selling it to others after price increase. On October 29, 2008, the State Administration of Taxation announced the "reply on the issue of collecting personal income tax from indivials' income from online trading of virtual currency"
in response to the Beijing Local Taxation Bureau's request for instructions on how to calculate and levy indivial income tax on indivials' income from online sales of virtual currency, the State Administration of Taxation has clearly stipulated that the income obtained from indivials' online purchase of players' virtual currency and sale to others after price increase belongs to the taxable income of indivial income tax, The indivial income tax shall be calculated and paid according to the item of "income from property transfer"
at the same time, the State Administration of Taxation emphasizes that the original value of an indivial's property selling virtual currency is the price and related taxes paid for his purchase of network virtual currency. If an indivial is unable to provide evidence of the original value of his property, the original value of his property shall be verified by the competent tax authorities Reporter Zhao Peng)
the tax rate of selling virtual currency is fixed at 20%
on October 29, 2008, the reporter called Beijing Local Taxation Bureau, and the relevant person in charge disclosed that the tax rate of paying indivial income tax according to the "income from property transfer" project is fixed at 20%, and Beijing Local Taxation will also introce relevant measures to verify the original value of indivial selling virtual currency property
according to the introction, Beijing Local Taxation Bureau has not yet started to levy indivial income tax on the income of indivials from online sales of virtual currency. However, the bureau is aware that this kind of behavior is already a relatively common phenomenon, which should be strengthened. In order to better implement the requirements of the State Administration of Taxation on the "reply to the issue of personal income tax on the income of indivials from the sale of virtual currency through the Internet", Beijing Local Taxation Bureau will also issue relevant operational measures to verify the original value of the property of indivials selling virtual currency

half life refers to the time when the mining reward (= new circulation) of bitcoin and other virtual currencies is reced by half

examples of terminology usage

cryptocurrency bitcoin (BTC) will reach its third half-life on May 12, 2020, and the mining reward will be reced from 12.5 BTC to 6.25 BTC

detailed description

many virtual currencies have "issuance limits" to prevent inflation, and the new issuance will be reced by half every certain interval of half-life. This is also a noteworthy event unique to virtual money, because with the decrease of supply and the rising of price, the scarcity value increases significantly
