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
in the current situation, blockchain is not a mature technology. What the market values is the so-called prospect, and it will take time to improve and excavate it slowly. However, the collapse of virtual currency is just a return to its own value
in short, I think bitcoin will continue to grow slowly after falling below a certain price. The current slump is just that the funds attracted by the previous heat have discovered the characteristics of virtual currency (hacker attack, dealer trading, these two situations will probably only appear in the newly issued currency, which is determined by the characteristics of blockchain, in other words, Hackers may also attack bitcoin in the early stage, but the more people and nodes bitcoin enters, the lower the probability of this situation, and the more difficult it is to generate)
in addition, I think that a large number of people in China even don't know what bitcoin is, so they are ready to make a fortune with money.
virtual currency is a kind of technical means, there is no such thing as whether to cheat or not in recent years, mobile phone development has been developing faster and faster, and there are also changes in the way of payment. In the life, a small number of people have paid for paper money. Most of them have started using Alipay, WeChat and so on, because they are popular with the public because of their convenience and speed, especially Alipay is the way that many people will pay when they pay. Many other procts have been used to facilitate many people, but Alipay has recently banned the trading of virtual currencies. P> Alipay is also making this decision in order to safeguard the interests of everyone. We should also pay attention to investing when we invest normally, so we can only buy it after thorough understanding. can not blindly listen to other people's views and invest carefully. strong>
when it comes to virtual currency, many people may be familiar with it. But there are also many people who are not clear about the concept of virtual currency. They will think that sina u, Netease popo and Shanda Yuanbao are all part of virtual currency. What's more, they think that these so-called virtual currencies will affect the status of RMB and proce adverse effects such as virtual inflation
first of all, let's understand the two meanings of virtual currency in economics
the prototype of the first virtual currency is composed of the weights of the currencies of a country's major trading partners, which is a non-existent currency in order to maintain the stability of the country's exchange rate.
The essential value of any kind of currency is that it can be used as the value scale to measure other things and has stability. The virtual currency here is not game currency, but a digital cryptocurrency like bitcoin. The bottom layer uses blockchain technology, which has the characteristics of decentralization, information tampering and anonymity. At present, cryptocurrency headed by bitcoin can not bear the property of currency. It is not fair to conclude that there is no value
a consensus has been reached in the currency circle by default, that is, bitcoin is similar to diamonds in the real world. The value of diamonds is given by businessmen, and it has been agreed that diamonds can symbolize love and have practical properties. Mining diamonds and gold also need to consume a lot of costs, but it is because a lot of costs are consumed that the constant intrinsic value of diamonds and gold can be ensured. The resources that can be obtained casually are prone to inflation< br />
The fall in 2018 makes investors return to rationality, which is actually concive to the standardized development of the currency circle. Now, regardless of the practical value of digital currency, this capital harvest makes investors further understand the importance of risk management. Money circle and Internet Finance allow investors to see that they are profitable, so they don't have to think about investing in it. It is ultimately their own loss. Whether this bear market can make investors understand the essence of money circle is still unknown. However, the future development of the coin circle still needs government regulation, as well as the regular operation of platforms and projects. Of course, only with the support of capital can the coin circle develop healthily and systematically. Therefore, capital outflow is the biggest reason for bitcoin's sharp decline.
as for the so-called tmall global digital currency, I don't know what it means
digital currency generally refers to bitcoin, Leyte coin, Ruitai coin, DCT and other open source cryptocurrencies.
The top deviation means that the stock price trend continues to rise, but the corresponding index trend has not risen, but has fallen, forming the top deviation.
the bottom deviation means that the stock price trend is still falling, but the index and stop falling have a rebound trend, thus forming the bottom deviation.
in short, the stock price trend and index trend are running in the opposite direction, resulting in the deviation phenomenon.
the text is not intuitive enough,
the following graphs are the top and bottom deviation of MACD, the top and bottom deviation of KDJ, the top and bottom deviation of CCI, and the automatic line drawing index. The results of automatic line drawing when the deviation occurs.

There are three uses of rod mill:
1) rod mill is often used in gravity separation or magnetic separation plant of tungsten tin ore and other rare metal ore in order to prevent the harm caused by over crushing
2) when the two-stage grinding process is used, if the first stage is from 20-6 mm to 3-1 mm, and the rod mill is used as the first stage grinding equipment, the proction capacity is larger and the efficiency is higher. Because the surface area of a certain weight of rod load is much smaller than that of the same weight of ball load, the proctivity and efficiency of rod mill are lower than that of ball mill in the second stage of fine grinding
3) in some cases, it can replace the short head cone crusher for fine crushing. When dealing with softer or less hard ores (especially those with high viscosity) and grinding 19-25 mm (or even 32 mm) ores to 6-10 mesh with rod mill, the configuration is simpler and the cost is lower than that with short head cone crusher and screen in closed circuit, and the st removal of crushing workshop can be simplified. For hard ores, it may be more economical to use the short head cone crusher to form a closed circuit with the screen. Whether ball mill or rod mill should be used in the design must be determined by making plans according to the specific situation and comparing them
rod mills are widely used in metal and nonmetal mines, water conservancy and building materials departments to grind various ores or rocks
1. The material to be processed is one, and the cutting tools are combined. In principle, the cutting force should be calculated according to the maximum diameter or the maximum removal position
2. The materials to be processed are various combinations, and the cutting tools are combined. In this case, the cutting force should be calculated according to the most difficult material characteristics and the maximum cutting tool position.
