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

In theory, if the existence of network currency affects the demand for the central bank's liabilities, and then interferes with the central bank's open market operation, it will have an impact on a country's monetary policy and price stability. However, from a practical point of view, the premise of network currency affecting price stability includes the following three aspects:

(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

However,
however, most Internet money systems operate in prepaid mode, that is, issuing Internet money when the real money is exchanged in and withdrawing money when the real money is exchanged out. In the famous network currency scheme, the supply of money is stable and the supply is small, but we still need to be vigilant whether it can ensure that the money supply will maintain a stable level in the long run, and the impact of the change of exchange rate between network currency and real currency

(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

The influence of network money on real money supply depends on two aspects: one is the substitution effect of virtual economy on real economy; the other is the substitution effect of virtual economy on real economy; The second is the crowding out effect of Internet money on real money, that is, with the increase of the total amount of Internet money, the amount of cash held by the public in real life decreases, resulting in the decrease of cash / deposit ratio and the increase of money multiplier. In reality, the network virtual currency scheme will not affect the price stability at this stage, and the money flow speed will not be significantly affected in the short and medium term. However, the interaction between network currency and real economy deserves attention

(2) financial stability risk when the virtual currency scheme operates outside the banking system, the most important factor of financial instability lies in its connection with the real economy, namely exchange rate and exchange market. Obviously, the closed network currency scheme and the one-way flow network currency scheme are not affected, so we should focus on the two-way flow network currency scheme. The value of two-way network currency depends on the level of money supply and demand in the exchange market. A big difference between network currency and real currency is that the network currency scheme is not based on the country or currency region, and the influence of virtual economy intensity, trade or proction capacity on its exchange rate is limited. The price of virtual money and its fluctuation depend on five factors:

(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

(2) the network currency scheme shows network externality, and its monetary value depends on the number of users and merchants. As the number of consumers and businesses increases, their monetary value will increase accordingly. In addition, the exchange rate of network currency with small transaction volume fluctuates more

(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

(3) stability risk of payment 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

(4) risk of absence of supervision generally speaking, supervision lags behind the development of science and technology. The network virtual currency program was established in the late 1990s, but it was not until 2006 that some government agencies in the United States began to analyze these programs. Due to the lack of
supervision and the anonymity, invisibility and difficulty in tracking of its transactions, the network virtual currency scheme is very easy to be used by terrorist activities, fraud, money laundering and other illegal activities. At present, many government departments in many countries are considering whether to recognize or
legalize these virtual schemes and bring them into the scope of supervision, so as to support the innovation of currency and payment forms, protect the rights and interests of consumers and financial stability, and inhibit the use of virtual currency schemes to engage in criminal activities
at present, the uncertainty of the legal status of the virtual currency scheme may also bring challenges to the government authorities

(5) reputation risk of monetary authority the reputation of Monetary Authority (central bank) is the key factor to determine the effectiveness of monetary policy. The public's trust in fiat money is closely related to the image of the central bank, which pays close attention to its reputation. The ECB defines reputation risk as the risk of deterioration of reputation, credit or public image. As the network currency scheme is related to money and payment, it is generally believed that it belongs to the responsibility of the central bank, so we should be alert to the reputation risk it may bring to the central bank. However, in the case of small scale, the impact of the failure of the network currency scheme is limited, but its high volatility and instability also aggravate the possibility of failure and attract extensive media coverage. If the network currency is allowed to develop continuously without
regulation, the central bank may be considered as dereliction of ty and affect its reputation

(6) the risk of investors' loss
for exchange value, the public has a higher recognition of the investment value of network virtual currency, and it is investment based transactions that accelerate the formation of virtual currency market. Like other investment markets, participants in virtual money market will also face potential losses caused by market risk, credit risk and policy risk. Take bitcoin as an example: from 2009 to early 2010, bitcoin was worthless; In the summer of 2010, bitcoin trading began to enter the golden
period. As the supply was far less than the demand, the value of online trading began to rise. In early November, bitcoin was silent at 29 cents for many days, and then jumped to 36 cents; In February 2011, bitcoin continued to appreciate, and its exchange rate with us dollar
reached 1:1; In 2013, the price of bitcoin achieved a "Big Bang" growth, and hit US $1242 on November 29, 2013, surpassing the gold price of US $1241.98/ounce in the same period. Fierce price fluctuations make market participants face huge speculative risks. Unlike mature capital markets such as stocks and bonds, the depth of bitcoin market is insufficient, and it is mainly held in the hands of large investors with low degree of diversification. Bitcoin price is easily affected by large investors' buying and selling behavior, and also easily manipulated by speculators. At the same time, different countries have different attitudes towards bitcoin, Germany, the United States and other countries hold an open and supportive attitude, and Thailand, Brazil and other countries regard bitcoin related activities
as illegal. Every country's attitude and measures will have a significant impact on the price of bitcoin, especially in the short term

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

5. Network virtual currency can be roughly divided into
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency. For example, the token of various physical assets on the European crowdfunding platform
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.

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

the rewards earned by the virtual currency exchange binance in the mining pool can be directly traded by binance

detailed description

in the mining business of vital scale, a mechanism for multiple miners to cooperate in mining. The reward is paid according to the contribution of the mining

7. Half life

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
