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

The top ten virtual currency trading platforms are: bitcoin China, Ethereum, Monroe, dascoin, reborn, etc.
Bitcoin China (BTCC), the first and largest bitcoin trading platform in China, is operated by Shanghai satuxi Network Co., Ltd., which was established on June 9, 2011. The team members are mainly from China, Silicon Valley and Europebitcoin China provides a reliable trading platform for users to buy and sell bitcoin through RMB
users can also save bitcoin safely in the platform
bitcoin China has achieved the best balance between high security and user convenience
4. Monro (code name XmR) is an open source cryptocurrency founded in April 2014, which focuses on privacy, decentralization and scalability. Unlike many cryptocurrencies derived from bitcoin, monero is based on cryptonote protocol and has significant algorithm differences in blockchain fuzziness
Dash, formerly known as dark coin, is a technical improvement on the basis of bitcoin. It has good anonymity and decentralization. It is the first digital currency with the purpose of protecting privacy. You can feel that it is liked by the black market when you listen to its name The main characteristics of Dashi coin are as follows:1
2. Instant payment function, timely arrival and low handling charge
Here are some personal experiences in the exchange
(1) the coin search website has the advantages of low service charge, quick withdrawal and multiple currencies. It supports a variety of well-known virtual currency transactions and is convenient to purchase usdt. It has app and high security
(2) kucoin overseas version (coin win background) has smooth interface operation, and the speed of coin withdrawal is not bad, but most of them are junk ICO coins, many names have not been heard of, such as app
(3) China bitcoin overseas version EXX (slow coin withdrawal, kengdai) gambling platform, fixed-point blasting futures pop you up, there seems to be a problem with cash withdrawal, no app
(4) fire coin overseas version, Collude with OK, dozens of junk money a week, no bottom line, many small problems. Support C2C transactions, there are app
(5) okcoin overseas version, this does not say, OK life black, although support C2C transactions, but bottomless line shelf circle coins, flicker leeks, C2C transactions can not be withdrawn, embezzle the user's assets after the decimal point of tens of millions, careful into
(6) BTCC overseas version, support us dollar UnionPay direct charge, but the handling charge is high, it is relatively low-key in China, The experience of the transaction interface is very poor
(7) the overseas version of cloud coin has few currencies and many problems, so it's all warriors
(8) currency security is currently the largest exchange in China, with the most complete currency and many activities. It doesn't card you to withdraw and recharge money. Although there are so many junk money in ICO, it doesn't have as many problems as hot money OK platform. It can be said that it is the best exchange in China. It has app, needs to turn Q, and mobile client doesn't need to turn Q
(9) Yuanbao overseas version has Canadian financial license, legal operation, insufficient depth, small amount of currency, small transaction volume and insufficient UI beautification
(10) in the bitage, the overseas version takes a very long time to review, and it takes you a long time to pick up the coin and issue the coin. The miner's fee used to be a little higher, but now it's just a little higher. 0.5% for recharge, 1% for withdrawal, and the highest withdrawal fee in the whole universe. The garbage made by the K-line chart can't hold on to the ICO coin. At present, this platform can't stand the temptation of interests, and the card is only issued half a day, The trading volume is a little less. At present, I have abandoned this platform
(11) the overseas version of China's bitcoin has just been opened for trading, and C2C trading has a unique qash trading area. There are many small problems, so be careful to enter
in the era of material abundance, money can buy what you want and enrich your life. Therefore, people have a dream of realizing wealth freedom and entering a better life there are many such dreams, which are often used. With the development of the Internet, online transactions have become more convenient and fast, people's financial management ideas have improved, and they will take spare money to invest, but the bank interest is low, the fund will not choose, and the stock water is too deep. Generally speaking, the income can't tempt greedy people
1. It is illegal to have a financial trading platform that is not recognized by China Securities Regulatory Commission and China Banking and Insurance Regulatory Commission. With the concept of blockchain being put forward, virtual currency has become popular. In China, there are bitcoin, Leyte coin, Ruitai coin, etc. the income of these virtual currencies has been blown to be amazing. People who listen to these virtual currencies will be envious and have new illusions. They don't know that this is just a Ponzi scheme, and the virtual currency trading platform will trick investors into inviting them, After the investors' funds are cheated, there will be a series of figures. Some of them will fall sharply as soon as they buy, and smart people can stop losses. Some of them will go up sharply when they buy, and investors will continue to add chips, and finally they can't cash out
Shanzhai currency trading platform: jucoin, bitage, Xigu digital asset trading platform.
if you want to trade other counterfeit currencies, you can choose the mainstream counterfeit currency trading platform. There are many currencies that support trading, such as jucoin, Xigu, bitage and so on.
another simple way is to use the generalized RBF network, which can be realized directly with GRNN function. The basic form is y = GRNN (P, t, spread). You can use help GRNN to see the specific usage. The prediction accuracy of GRNN is good
generalized RBF network: from the input layer to the hidden layer is equivalent to mapping the data in the low dimensional space to the high dimensional space, and the number of cells in the input layer is the dimension of the sample, so the number of cells in the hidden layer must be more than that in the input layer. From the hidden layer to the output layer is the process of linear classification of data in high-dimensional space. The learning rules commonly used in single-layer perceptron can be used. See neural network foundation and perceptron
note that the number of neurons in the hidden layer is greater than that in the input layer, and it is not equal to the number of input samples. In fact, it is much less than the number of samples. Because in the standard RBF network, when the number of samples is large, many basis functions are needed, the weight matrix will be large, the calculation is complex and prone to ill conditioned problems. In addition, compared with the traditional RBF network, the wide RBF network has the following differences:
1. The center of the radial basis function is no longer limited to the input data points, but determined by the training algorithm
2. The expansion constant of each radial basis function is no longer unified, but determined by the training algorithm
3. The linear transformation of the output function contains threshold parameter, which is used to compensate the difference between the average value of the basis function on the sample set and the target value
therefore, the design of generalized RBF network includes:
1. Structure design -- the hidden layer contains several nodes, which is suitable
2. Parameter design -- the data center and expansion constant of each basis function, and the weight of output nodes.
