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

Application of digital currency
I. fast, economic and safe payment and settlement
cross border payment helps RMB internationalization. In 2015, the settlement volume of cross-border payment involving current account is about 8 trillion yuan. To accelerate the internationalization of RMB, cross-border payment and settlement procts and solutions with low cost, high efficiency and low risk are needed
At present, there are still a lot of repetitive human work in the bank's electronic loan process and processing process, and as the basic support of loan issuance, many of the collateral has the situation of false pricing or multiple or even no collateral. We can consider using digital currency to price and track bank collateral:3. Bill finance and supply chain finance
in recent years, various bill market businesses based on commercial bills have grown rapidly, and bill financing procts have become a hot area of Internet financing. However, about 70% of the current bill businesses in China are still paper transactions, Supply chain finance is also highly dependent on labor costs

network digital currency
The Internet of things in China refers to a network concept in which information sensing devices such as GPS, laser scanners, etc. connect any item with the Internet according to the agreed protocol for information exchange and communication, so as to realize intelligent identification, positioning, tracking, monitoring and management. The rudiment of the Internet of things is just like the early form of the Internet, local area network, which shows a great prospect
digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold
risk
digital gold currency is a form of physical currency, whose deposits are measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value
since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self-regulation way. Digital gold money suppliers are not banks, so banking regulations are not applicable. However, the global digital currency Association, founded in 2002, is a non-profit association of online currency operators, convertors, merchants and users. This association supervises the users' reports and ratings the reputation of the convertor. The rating operation is confirmed by the users' reports
criticism
digital gold money suppliers and changers have been accused of being intermediaries of fraulent hyip schemes. In January 2006, business week reported that shadowcrew used the e-gold system, involving a large number of online groups whose identity information was stolen. However, the chairman of e-gold claimed that he would not compromise on any criminal activities using e-gold

Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
the school enterprise alliance of Internet of things in China defines the Internet of things as the combination of almost all technologies, computers and Internet technologies, realizing the real-time sharing of environment and state information between objects, as well as intelligent collection, transmission, processing and execution. In a broad sense, the application of information technology can be included in the category of Internet of things, which is the most direct embodiment of the integration of science and technology
digital gold currency is a kind of electronic currency named after the weight of gold. The typical unit of measurement for this currency is the Troy gram or troy ounces, although sometimes the golden Dinar is used. Digital gold currency is funded by gold storage without quota or decentralized quota. By January 2006, digital gold currency suppliers held more than 8.6 metric tons of gold as reserves, worth about $154 million
the difference between digital currency, electronic currency and virtual currency
in fact, digital currency is a kind of indexed RMB, a legal encrypted digital currency and an alternative currency in the form of electronic currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
it can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual spaces. It is different from Alipay and WeChat, and Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. The popular digital currencies in 2016 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world
virtual currency refers to the non real currency, especially the currency in the network virtual economy. The issuer is not the central bank, and it can only circulate in a specific virtual environment. In the case of the connection between virtual and reality, virtual currency has its real value. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point, roll counting of Shanda company, u-coin meter ticket launched by Sina (used for igome game), chivalrous Yuanbao (used for chivalrous road game), and grain silver (used for bixue Qingtian game). Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. For example, bitcoin is illegal digital currency
since the beginning of the year, the relevant person in charge of the people's Bank of China has said that the future of mobile payment is bright, and the central bank is actively studying the relevant research results and practical experience at home and abroad to strive for the early issuance of digital currency. At the digital currency seminar of the people's Bank of China held on January 20, the relevant person in charge of the people's Bank of China disclosed that the central bank has set up a special research team since 2014 to conct in-depth research on the digital currency issuance and business operation framework, key technologies, circulation environment, etc., and strive to launch the digital currency issued by the central bank as soon as possible. At present, the research has achieved phased results
what benefits will digital currency bring to our lives
for this problem, the relevant person in charge of the central bank said that if the digital currency is successfully issued, it will bring many conveniences: it can effectively rece the high cost of the issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transaction activities; It can rece money laundering, tax evasion and other illegal and criminal acts, enhance the central bank's control over money supply and money circulation, better support economic and social development, and help the comprehensive realization of Inclusive Finance; It helps to build a new financial infrastructure, further improve the payment system, improve the efficiency of payment and clearing, and promote the upgrading of economic quality and efficiency. More digital currencies can focus on bitMom
There is no relationship between digital currency and Internet of things.

the application fields of digital currency and Internet of things are different
1. Internet of things:
through a variety of information sensors, RFID technology, global positioning system, infrared sensors, laser scanners and other devices and technologies
Digital currency:is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
extended data
through various possible network access, the Internet of things realizes the ubiquitous connection between things and people, and realizes the intelligent perception, identification and management of goods and processes. The Internet of things is an information carrier based on the Internet and traditional telecommunication network. It enables all ordinary physical objects that can be independently addressed to form an interconnected network
and digital currency can be considered as a virtual currency based on node network and digital encryption algorithm, which mainly applies fast, economic and secure payment and settlement, establishes digital wallet through digital currency, realizes lower cost and more secure micro payment and capital transfer in areas with insufficient financial coverage and underdeveloped economy, and increases intermediate business income
F= ρ S(v*sin θ)^ 2
the formula is deced as follows:
consider the case that the wind speed is perpendicular to the action surface first
take the cross section of the wind as s and the length as S Δ x( Δ x-> 0), and the velocity before the wind contacts the action surface is v Δ x=v Δ T
the mass of the air column is Δ m= ρ S Δ x= ρ Sv Δ T
because the mass of the air column is very small, when it collides with the action surface, it will move along the action surface, that is, its velocity perpendicular to the action surface is 0 Δ t=0-(- Δ MV)
i.e. F Δ t= ρ Sv Δ t*v
F= ρ When the wind speed is not perpendicular to the action surface, the velocity is divided into the direction of the vertical action surface and the direction parallel to the action surface. Since the component parallel to the action surface will not generate force with the action surface, the final wind force is only the component perpendicular to the action surface, which is v * sin θ, Substituting this formula into (*) to get
F= ρ S(v*sin θ)^ two
bitcoin, Ruitai coin, dogcoin and other digital cryptocurrencies are all originated from the Internet.
