It is illegal to issue virtual currency privately
According to Article 29 of the regulations of the people's Republic of China on the administration of RMB, no unit or indivial is allowed to print or sell token tickets to replace RMB in circulation on the market In addition, the "emergency notice of the State Council Office for rectifying unhealthy tendencies in the instry, the State Economic and Trade Commission and the people's Bank of China on prohibiting the issuance and use of various token certificates (cards)" also strictly prohibited similar issues 
extended data
virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
market formation
the Internet has led to the emergence of a new market, which is a virtual market based on cyberspace. The Internet provides a lot of communication places for consumers, and also provides business market for enterprises. Enterprises must change from proct centered to service centered to customer centered. With the development of computer artificial intelligence technology and database technology, enterprises can conveniently collect customers' information, understand customers' needs in time, change business strategies and grasp economic arteries in real time
With the rapid development of computer and network communication technology, the application of Internet technology has graally penetrated into various fields of human activities, and the unlimited business opportunities that it contains make businesses turn their eyes to e-commerce. E-commerce is penetrating into all aspects of social and economic life at a speed that people can hardly imaginethe traditional finance is also closely watching this irresistible trend of global economic integration and networking. As a result, value-added services take art as the selling point and can be regarded as commodities; The sword in the game is not a brand-new financial services business philosophy - e-finance came into being
from the historical development process, to understand e-finance, we must start from the electronic finance and e-commerce. The so-called e-financialization means that financial enterprises adopt modern communication, computer, network and other information technology means in addition to Internet technology to improve the work efficiency of traditional financial service business, rece operating costs, realize the automation of financial business processing, informatization of financial enterprise management and scientific decision-making, and provide customers with faster and more convenient services, And then enhance the financial enterprise is the behavior of market competitive advantage
e-finance is a transcendence of financial electronization. Different from the electronic finance, the main technical basis of e-finance operation is the increasingly perfect Internet technology. Due to the characteristics of global connectivity, openness, quickness and low marginal cost of Internet technology, e-finance strengthens the restructuring and innovation of financial services business based on Internet technology, so that customers are free from the restrictions of business hours and places, and enjoy all kinds of high-quality and low-cost services provided by financial enterprises anytime and anywhere
with the development of Internet, the form of money is becoming more virtual, and there is an electronic money that only exists in the form of electronic signal
reference source: Network: virtual currency
on the other hand, with the rapid development of mathematical economy, people generally pay attention to whether virtual currency will enter the popular payment and transaction scene.
[answer analysis] analysis of the test questions: ③ and ④ the options are correct and in line with the meaning of the question. Bitcoin in the question has its own particularity. Compared with currency, bitcoin does not have the universality of currency and can not be called currency, which indicates that the particularity cannot be separated from universality. Bitcoin can buy virtual goods, exchange money, and even buy real goods, But these are all phenomena, and bitcoin is not issued by the state, and it does not have legal taste and mandatory currency. This is the essence of things, so it is judged that bitcoin is not a currency, so it is selected. ① (2) the point of view of the option is not consistent with the meaning of the title. The title emphasizes that bitcoin is not a real currency compared with currency. It does not emphasize the specific analysis of specific problems, nor does it involve grasping things in the development, so it is excluded
test point: this question examines the relationship between universality and particularity of contradiction, and conscious choice of consciousness
bitcoin plummeted. I have no experience of buying virtual currency. I advise those who want to speculate in digital currency not to enter the market in the near future, which may lead to economic losses the earliest digital currency is private digital currency. The origin of cryptocurrency is bitcoin, which appeared in 2008. Later, Ethereum appeared. Because of its anonymity and decentralization, cryptocurrency has been recognized by more and more people, and the scale of global private money market is expanding. At present, there are more than 5600 digital currencies in the private money market
Computer algorithm is a step-by-step way to describe in detail how the computer transforms the input into the required output process, or algorithm is a specific description of the calculation process executed on the computer
an algorithm must have the following properties:
(1) the algorithm must be correct, that is, for any group of inputs, including reasonable inputs and unreasonable inputs, it can always get the expected output. If an algorithm can get the expected output only for the reasonable input, but can't expect the output result in the abnormal situation, then it is not correct
(2) the algorithm must be composed of a series of specific steps, and each step can be understood and executed by the computer, rather than abstract and fuzzy concepts
(3) each step has a definite execution sequence, that is, where is the last step; What is the next step must be clear and unambiguous
(4) no matter how complex the algorithm is, it must end and terminate after finite steps; That is, the steps of the algorithm must be limited. In any case, the algorithm can not fall into an infinite loop
a solution to a problem can be expressed in many ways; But only the solution satisfying the above four conditions can be called algorithm
extended materials:
algorithm can be roughly divided into basic algorithm, data structure algorithm, number theory and algebra algorithm, computational geometry algorithm, graph theory algorithm, dynamic programming and numerical analysis, encryption algorithm, sorting algorithm, retrieval algorithm, randomization algorithm, parallel algorithm, Hermite deformation model, random forest algorithm
algorithms can be broadly divided into three categories:
one, finite, deterministic algorithms, which terminate in a limited period of time. They may take a long time to perform the assigned task, but they will still terminate within a certain period of time. The result of this kind of algorithm often depends on the input value
Second, finite and uncertain algorithms, which terminate in a limited time. However, for a given value, the result of the algorithm is not unique or definite Thirdly, infinite algorithms are those that do not terminate because there is no defined termination condition or the defined condition cannot be satisfied by the input data. In general, the infinite algorithm is e to the undetermined defined termination condition
