Prediction of virtual currency
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. How do I pay? When I pay from address a to address B of the other party, the payment amount is e. at this time, both parties will announce the transaction information to each network node, telling address a to pay to address B, and the payment amount is e. In order to prevent the third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. at this time, the network node receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU intensive. How to let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC
It's hard to say that the value of bitcoin depends entirely on other digital currencies. Many digital currencies anchor the rise and fall of bitcoin. Moreover, although bitcoin itself limits the number of issues, its lower limit is wireless issuance. Compared with the most popular 21 million, it has been issued nearly 100000 times. Moreover, it lacks supervision, Its price is completely controlled by some capital parties and teams, becoming a tool for capital to harvest leeks
according to my estimation, the value of bitcoin will continue to rise, and it will continue to be issued, which is equivalent to a big plate. In order to attract more people into the pit, bitcoin must rely on the rise to attract investors, and then harvest through the control panel. This can also be seen from the rise and fall of bitcoin in the past five years, And the change of funds< br />
In the environment of virtual currency trading, the fluctuation of the currency market is weaker day by day. According to Du Dongfeng, an analyst of the medium and long-term currency Commission network, the medium and long-term cycle should be a downward trend of inter district fluctuation. The price fluctuation in the range of 8000-4500 in this year is more likely, and the currency market may continue to fluctuate for a long time. The intraday fluctuation range may shrink again, and the intraday fluctuation range within $100 may become a high probability event! The weakening of the mainstream currency range will undoubtedly affect the profit margin and lengthen the trading time of medium and long-term trading. For investors, the rate of return and capital occupancy will be greatly reced! Therefore, the general virtual currency trading or short-term or into a virtual currency position trading short-term trading trough. But the popularity of virtual currency trading is still on, so users of virtual currency trading are likely to find a neutral proct in the derivatives of virtual currency trading to replace the vacancy of virtual currency position trading. Du Dongfeng, an analyst at cnki.com, believes that short-term trading of virtual currency will be the best choice for the next round of virtual currency fever
what is virtual currency short-term trading
There is no doubt that the short-term transaction of virtual currency can be understood literally as the short-term transaction mode of virtual currency. The short cycle trading mode of virtual currency is a new way to play in the virtual currency market, and it is also a popular derivative proct of virtual currency trading in this year. Its trading mode can be understood as: fixed investment amount to judge the market fluctuation direction of fixed time cycle. Transaction amount and fixed transaction profit and loss can be predicted. It means that transaction costs, gains and losses are controllablefor example: when trading on the short-term trading platform of virtual currency, Xiaoge found that the short-term fluctuation of bitcoin was in a small downward trend at that time (the price of bitcoin was 6666.66 at that time), and predicted that the market would start to fall in five minutes. He made a five minute drop of 100usdt bitcoin at this price, and when the closing price of bitcoin was lower than or equal to 6666.65 five minutes later, Then I can get 180 usdt of income (including 100 usdt of transaction principal). If the closing price is higher than 6666.67 after five minutes, the single transaction will be at a loss
as shown in the figure:
generally, the lowest transaction is from 5usdt, and a single transaction may reach 1000usdt or higher. The transaction time cycle is generally 1, 2, 5, 15, 30 and 60 minutes, and the rate of return is also determined according to the time cycle
I think if we want to keep up with the upsurge of virtual currency, we can pay attention to the short-term transaction of virtual currency! Because in any investment, investors at the forefront are the most profitable and still belong to the first group to eat crabs! More related consulting money commission network, money commission network is not only to provide you with a virtual currency trading platform, but also a virtual currency instry leader! The short-term transaction of virtual currency is undoubtedly the derivative proct of virtual currency transaction, which accelerates the virtual currency transaction to the super short-term stage
world wide steel, pseudonym, physicist and scientific author. He is the author of the best-selling book "never expected: understanding the world with science and engineering thinking". The purpose of his article is "understanding the world with science and engineering thinking". He likes science and politics, and emphasizes rationality and modernization
this is a preface written by world wide steel for the new book intelligentsia: being a complex modern man (Electronic Instry Press, February 2016). The surging news is published with the authorization of the author< This is a book about the modern world. I want to talk about something in this book that a modern person should have, and only a modern person can have; Wisdom & quot—— Wisdom and insight. If you want to understand the modern world and even make some decisions, you have to have this kind of wisdom
from the perspective of social change, the ideas to be discussed in this book are quite new, and they have not yet become idioms and allusions to be written into our cultural genes. They are scattered among the latest developments in various disciplines and are often unknown to laymen. But these ideas do not need any professional knowledge to be understood and mastered. They have been spread among scientists, philosophers, engineers, entrepreneurs, entrepreneurs, university teachers and students, and people in all walks of life who are sensitive and interested in the modern world
these people are not just traditional & quot; Intellectuals;, It's & quot; Intellectual elements & quot
I used to be a physicist. I made a living in scientific research, but my achievements have not reached the level of daring to speak Chinese; Physicist & quot; The degree of self assertion. It is reasonable to focus on physics research, but I read a lot of non professional books and wrote a lot of articles that have nothing to do with physics. I don't do these unprofessional things because physicists have more free time, but it's really because the turbulent modern world is so interesting - I even think that if you don't get to know the latest ideas of the world well and just satisfy yourself with being an intellectual in a specific profession, you will be born in the modern world for nothing
and you may be in danger of falling behind. There are three important trends in the world at this moment, which challenge us intellectually< The first is that the world is becoming more and more complex< Economists love to talk with pencils. A pencil seems simple, but if you think about it carefully, the graphite lead, the wooden shell, the metal skin and the rubber of the pen head, from the extraction of the primary raw materials to the processing and assembly, you don't know how many hands have passed. No one has mastered the whole set of pencils; Craftsmanship;, What everyone knows is just one step
Hayek tells us that this is the power of the market. In fact, knowledge is decentralized and distributed among people. It is the market that organizes people to work together. So if you only know the same knowledge, no problem, as long as you make a reasonable response to the price signal, you can live a good life. On the other hand, if someone wants to have all the knowledge, try to take charge of the whole situation and even make plans, he can only help
but the modern world is more complicated than the traditional pencil workers. If I'm a pencil worker with low salary but a little modern consciousness, I want to ask why I can't get high salary. I need to know something about economics. I would also like to suggest that factories print some words and patterns on pencils to promote sales, which probably involves psychology. I am concerned about the stability of my work. Some people say that the pencil instry is dying. How can I evaluate the credibility of such comments? Will I be replaced by robots? How should I engage in office politics with my boss? If I want my children to work at a higher level in the future, should I focus on exam oriented ecation or quality ecation
no one only knows to stare at price signals. These are the real situations of modern people: they face many problems every day. How to answer these questions? In fact, most people's way is to imitate others, because it's useless to think for themselves, and it's useless to watch the romance of the Three Kingdoms, the art of war, and the study of the thick black - the experience and ideas adapted to the traditional simple society are becoming less and less adapted to the modern society
the second trend is that artificial intelligence is graally replacing people's work
I will elaborate on this in the book. In short, the situation is much more serious than people think. So far, many livelihood skills, even some advanced skills, which are still easy to use, will soon be replaced by artificial intelligence. We are about to usher in an era of "changing people without changing ideas"
the third trend is that although the material life of all people is improving, the class stratification of the whole society is expanding
in recent years, studies on the gap between the rich and the poor have emphasized a point: the most important difference between the poor and the rich is not the amount of money, or even the number of opportunities, but the culture and concept. Poverty is not only an economic state, but also a mode of thinking. The difference in this mode of thinking is not only the difference in investment and financial management like "poor dad, rich dad", but also a whole set of things
for example, the degree of trust in strangers may reflect your class height. Some people have made an in-depth investigation of the social customs of Italian immigrant working-class communities in Boston area of the United States, and found that for these people, family members, relatives and acquaintances from childhood to althood are far more trustworthy than any outsiders. They think that everything outside is mysterious and even hostile. Another British study found that the working class and the poor are more likely to say things that only their relatives and friends can understand, regardless of whether outsiders can understand them - while the middle class try to explain what they are saying to everyone
compared with the love of fellow countrymen and the dialect slang among alumni, what kind of class are most of us? Is it easy for us to fall into the thinking mode controlled by the traditional acquaintance society and even the evolutionary psychology from the primitive society? Do we have the rational thinking advocated by modern society
the law of the world is not the chicken soup of the soul, so I have to say that the backward mode of thinking is difficult to change. In the book, I will introce several studies that try to change the thinking of poverty, among which there are few successful cases
Keith stanovic, a Canadian psychologist, has a book called beyond Intelligence: why smart people do stupid things, which uses a lot of research results to explain a problem: intelligence and rationality are two different things, and they are almost unrelated. Rational ability - the ability to fully understand the current situation and make the best decisions - needs to learn from others
given the scarcity of high-quality ecation resources and the great differences in family culture among different classes, who is more likely to learn rationality
considering the previous two trends, the world is becoming more and more complex and difficult to understand, and artificial intelligence is forcing us to change our minds - in such a situation, how can the gap between the rich and the poor not be widening
these three trends will pose great challenges to us. It can be said that only a few people have the wisdom of modern society, and most people's thoughts still stay in the traditional society, some even stay in the primitive society
how to meet this ideological challenge? The first step is to listen to the experts< How to listen to the opinions of science and engineering experts
Science and engineering thinking is the most important modern thinking, which stresses tradeoff, quantification and scientific methods. My last book was called "never thought: understanding the world with science and engineering thinking". But make no mistake: if you are only satisfied with your own small field, an expert in science and engineering may not be able to understand the world with science and engineering thinking< In fact, experts in science and engineering probably have a problem. If someone asks you a question about insight, if you don't use your own professional knowledge to answer it, people will say that you are not an expert in this field at all; If you use the professional knowledge to answer, you are actually a tool for reference only< How do you say that? Few practical problems in a complex world can be solved with only one aspect of knowledge. It is said that a famous scientist in the United States was invited to talk about environmental protection on a talk show once and made a big difference. Scientists engaged in environmental related research must emphasize environmental protection, but this man is more extreme. He even said that CEOs of energy giants & quot; Committed a crime against humanity
experts like this can't take you seriously. It's us who use energy, but the CEO of energy company? And a crime against humanity? Obviously, the scope of knowledge of this scientist is too narrow. He only knows a little knowledge of his own subject and thinks that what he studies is the most important. He doesn't have tradeoff's mind at all, and he doesn't know the importance of other needs in society. As the saying goes, if you are not in charge of your family, you don't know the price of firewood and rice
in my opinion, this situation is quite common. Some scientists and engineers are not very knowledgeable on public issues, and they habitually overemphasize the importance of their own profession. Climate scientists who advocate global warming claim to rece carbon emissions at all costs, as if the economic scale is not a problem at all; People engaged in aerospace believe that every dollar invested in the aerospace instry can bring a return of seven dollars; People engaged in bioenergy say that nuclear power is particularly dangerous; Physics practitioners say that the electron positron collider is the most urgent scientific research project in China in the early 1980s... Only Mr. Yang Zhenning is the most fair: as a physicist, he says that the 21st century is the century of biology
therefore, the best way to treat science and engineering experts is to take their opinions as a reference for decision-making. You can provide me with the best argument data within your professional scope, but I have to listen to other people's arguments and data on how to make a decision
a gentleman has no tools. If you are only satisfied with being a technical expert in a certain small field, I'm afraid it's not enough to make public decisions at a large scale, and it's not enough to understand life at a small scale
then, can you listen to the liberal arts experts
3. Ideas and arithmetic
Science and engineering experts at least know the limitations of their knowledge, and liberal arts experts often think that they know everything. They don't travel in the world by & quot; Rationality;, It's by & quot; Concept & quot
many humanities, including economics, political science and sociology, are still at a very early stage, which is reflected in the fact that scholars have not reached a consensus on many major issues. They are divided into many factions, often labeled with & quot; ×× Doctrine & quot; Sometimes, it's just like the sects in the martial arts world. Keynesian economics believes that consumption stimulates growth, and the government should introce economic stimulus plan; Supply side economics believes that the real heroes are entrepreneurs, so the best stimulus is tax cuts. Liberal political scholars believe that government should play an important role in social life, while conservative political scholars demand small government
Sweden, a Nordic country with high tax and welfare, is a typical representative of big government. America as a Democratic Party
As we approach the end of the year, when we plan to sprint for the goal of the end of the year, earn more bonus and prepare to release ourselves in the Spring Festival, don't forget that the fraudsters also have such a plan. At this time, the tide of shopping on double 12 and new year's day comes one after another, and people working outside are also busy booking tickets and air tickets for the Spring Festival, which provides opportunities for fraudsters. Here, liewang, the first online fraud information reporting platform linked by the police and the people in China, makes an inventory of the new trends of online fraud in 2017. Can you see through all these scams
trend 1: mobile payment has become the mainstream, beware of two-dimensional code trap
mobile payment has greatly facilitated people's life and made people travel easily. However, there are many criminals who use the way of scanning two-dimensional code to carry out fraud, which is impossible to prevent. For example, on bike sharing, a fake QR code is used to cover the regular QR code, and the avatar is set as the official icon of bike sharing to cheat users to pay or recharge; Next to the store's two-dimensional code, there are words full of temptation, such as "scan code to grab red packets", "scan code discount", etc., to lure users to scan the code, and then obtain user information or directly guide users to transfer money. There are even criminals who the illegal parking notice posted on the car by traffic police. The fake ticket is attached with a payment QR code to lure the car owner to scan the code to pay a "fine"
trend 2: fake businesses want to refund. Users should be careful of being" loaned online "
generally, people think that their bank card balance is small, even if they encounter swindlers, it doesn't matter. However, according to the report cases received by liewang platform, In the common refund fraud in 2017, fraudsters use mobile phones to receive SMS verification code to lure victims into Internet micro loan business, and finally transfer the loan to the swindler's account. This kind of fraud often involves a high amount of money and brings serious property losses to users
trend 3: mobile phones also contain extortion virus, and the payment method is more" people-friendly "
mobile phone extortion software has become a common tool for criminals to seek benefits e to its low proction cost and fast cash flow. At present, there are different forms of blackmail software in the mobile application market. Different from the blackmail software in the computer, bitcoin is needed to pay for it. The payment form in the mobile blackmail software is more "people-friendly"
a batch of blackmail software captured in 2017 attached wechat two-dimensional code information to the blackmail interface, and prompted the winner to directly scan the two-dimensional code for payment by wechat, which will automatically unlock after successful payment, and the user will automatically enter the transfer interface after scanning the code. However, through technical analysis, this kind of blackmail software does not have any code related to wechat transfer. The so-called "scan payment, automatically unlock" is actually a fraud, even if the user transfers, it will not automatically unlock
trend 4: fake customer service requests to provide payment code and swipe only by numbers
because code scanning payment is simple and convenient, in 2016, many fraudsters took a screenshot of the two-dimensional code to swipe. But in 2017, as payment companies added anti fraud tips or confidentiality settings in the process of payment QR code screenshots, swindlers immediately thought of countermeasures and swindled the numbers under the payment code, forming a new instrial chain
criminals often disguise themselves as merchants customer service, requiring users to provide figures such as Alipay, WeChat and other payment bar codes, and then, on the grounds of digital failure, require users to refresh the numbers and send them several times to achieve the purpose of stealing. p>
trend 5: download the specified software, but the account password is shared by cloud disk
users' privacy information can be stolen without using phishing websites and Trojan horse software. This year, swindlers have come up with new tricks: as long as the victims' trust is obtained, they can download cloud disk, synchronization software and other procts, log in to the account designated by the swindler to upload files and synchronize, and then they can easily get information. What's more, if the user synchronizes the SMS verification code at any time, the swindler can easily steal the funds in the bank card
fraudsters often disguise themselves as e-commerce, suppliers and other customer services, requiring users to download some cloud disk synchronization software, and then provide the specified account password for users to log in. At this time, if the user logs in and synchronizes the personal account, password and other information on the software according to the swindler's instructions, the funds on the account will be transferred quietly
trend 6: new phishing websites on mobile terminals are more covert and easy to be recruited
as security manufacturers increase their efforts to crack down on phishing websites, phishing website makers also strengthen their covert means, spread links by using proct sharing functions such as short URL, cloud disk service, browser and social tools, and finally jump through the URL, Guide users to phishing sites to launch online fraud
trend 7: indemnity should be paid in intimate way. Be careful with this kind of fraud SMS
as early as 2013, 360 company discovered a high-risk fraud binding the victim's online banking account. In recent years, with the use of mobile payment becoming more and more popular, In 2017, there was a similar kind of fraud, which used a payment platform to bind accounts and swipe victims' accounts
in May 2017, Mr. Di received a flight delay text message sent in the name of the airline, with flight information and customer service phone number attached in the text message, and said that Mr. Di could get 300 yuan of delay compensation. Fake customer service in the phone to guide Mr. Di refund operation, and provide the enterprise account, but also ask Mr. Di to open intimate payment function. However, after Mr. Di opened, he found that he had two dections, and realized that Mr. Di was cheated and immediately called the police
trend 8: investment in the circle of friends? Do not gambler psychology
in everyone's wechat group or circle of friends, there are often many activities or proct recommendations under the banner of discount. Not long ago, Mr. Wang saw a WeChat official account named "double half price win" in WeChat group chat. Mr. Wang then identified the official account as having an enterprise certification and believed that the platform had high credibility. p>
Mr. Wang invested a small amount in the early stage, and found that there was a certain income every day, so he subsequently invested in batches, but graally began to lose money“ He wants to invest more in order to earn back the capital. As a result, when contacting customer service again, he found that the other party had blackmailed him. Only then did he realize that he had been cheated and that the money he had invested had gone to nothing
trend 9: identity impersonation has a new pattern, be careful that "friends" are high imitations
in the past, online fraud of identity impersonation often occurred on QQ, wechat and other social platforms, but this year, swindlers shifted their focus to microblog. The swindler specially studies the social habits of the victims, such as the relationship between microblog staff and chat content, and then changes their avatars and nicknames to create high imitation numbers. Because most of the fake users are abroad, it is difficult for their microblog friends to distinguish the true from the false in time
trend 10: the combination of various means makes it impossible to prevent the" ghost "fraud.
in March 2017, 360 assisted the Shenzhen police in successfully cracking down the" midnight ghost "Telecom fraud Gang, which the police identified as an illegal trade instry chain relying on personal information, It is a high-tech, high intelligence, cross platform, remote-control new type of telecom network fraud crime that combines mobile cloud service, operator's deputy number service and Internet financial service. And this kind of stealing brush mainly uses different services of various platform service providers. A single service does not have the security risk of stealing brush, but it is combined to form stealing brush. In order to make it difficult for the victims to detect, the criminals choose to commit crimes late at night. The whole process does not need to have any contact with the victims, and the victims do not need to reply to any SMS, so prevention is very difficult
from the above ten cases, the current situation of network fraud is still not optimistic. The anti fraud experts of liewang platform hereby remind the netizens that the new year is approaching, the fraudsters are highly active, and all kinds of fraud means emerge in endlessly. At this time, we need to improve the anti fraud awareness, so that the fraudsters have no chance to take advantage of it
net hunting platform is jointly launched by Beijing Public Security Bureau and 360. It is an innovative platform to crack down on Internet fraud through Internet platform and Internet technology. Up to now, liewang platform has established contact with public security organs in more than 300 regions of the country, helped to detect more than 100 major Internet fraud cases, involving 170 million yuan, and knocked down more than 10 large-scale fraud gangs with strict organization and clear division of labor. Internet users can report malicious programs, malicious web addresses, fraulent phone calls, etc. to 360 Internet security center through the platform. Every piece of information reported by Internet users will be included in the big data of liewang platform, providing effective clues for the police to solve cases
The price is determined by the market and is difficult to predict. We can pay more attention to the price of AE currency in the financial situation of Britain
he pointed out that many overseas countries have experienced a lot of monetary easing, and the pressure of inflation will continue to increase in the future in his first public appearance after joining Soochow securities, Ren Zeming put forward a view that in the next year, everyone's most concern is inflation expectations. Although the epidemic situation has graally improved, countries are increasingly dependent on monetary easing. Even if the economy has improved, the dependence on monetary easing is still going on, and even stronger than before. Because in the past year, the economic growth of various countries was basically driven by the stock market, and the real economy was stagnant
The people's Bank of China announced that with the approval of the State Council, from July 21, 2005, China began to implement a managed floating exchange rate system based on market supply and demand and with reference to a basket of currencies. The exchange rate system of RMB, which was originally pegged to the US dollar, has been changed to refer to a basket of currencies
since January 1, 2017, according to the CFETS basket selection rules, 11 new RMB to foreign exchange trading currencies listed in 2016 have been added to the CFETS basket, and the number of CFETS Basket Currencies has changed from 13 to 24, including US dollar, euro, Japanese yen, Hong Kong dollar, British pound, Australian dollar, New Zealand dollar, Singapore dollar, Swiss franc, Canadian dollar, Malaysian ringgit, Russian ruble, Thai baht, Singapore dollar, Singapore dollar and so on South African rand, won, UAE Dirham, Saudi Riyal, Hungarian Forint, Polish zloty, Danish krona, Swedish krona, Norwegian krona, Turkish Lira and Mexican peso
