Fried coins or something

at present, the application of blockchain technology is virtual currency. Therefore, virtual currency is also known as the first real birth proct of blockchain. The popularity of virtual currency is also obvious to all, which has set off a frenzy of investment in many countries. According to foreign media reports, the number of virtual currency transactions in the United States has reached 5 million; South Korea is estimated to be the craziest nation in the world, with one in every 50 people speculating, and 31% of the working class buying and selling virtual currency; Venezuela has also issued the world's first virtual currency with the nature of national sovereignty - oil currency

with the popularity of virtual currency, market investors are not only satisfied with the conventional trading mode of buying low and selling high, but also actively seek more simple and convenient trading ways to obtain more profits. The virtual currency trend trading method was born and successfully captured the hearts of investors in a short time, becoming a major mainstream trading mode

according to

{rrrrrrr}

, the trend trading method of virtual currency is exclusively launched by speedxo, an international financial service provider with deep experience. It mainly deals with the currency pair composed of virtual currency and real currency, and it can make profits as long as it is bullish or bearish. For example, if an investor trades in "bitcoin / US dollar", he or she only needs to judge whether the price will rise or fall after 30 seconds, and buy up or down according to the trend. If he or she buys in the right direction after 30 seconds, he or she can get 93% of the net income of the investment amount. It is this kind of rise and fall are profitable, time-consuming, no need to take advantage of the market, the trend trading method quickly swept the entire currency circle

Shenzhen's IT leaders summit has come to its 10th year. As the annual program of China's Internet giants gathering in Shenzhen, Shenzhen and its star enterprise Tencent are trying their best to entertain those bigwigs who come from afar

Zhang Shousheng, Professor of Stanford University, USA:

the generation of blockchain can create a data market. In my mind, the ideal future world is that everyone has their own data, which is a completely decentralized storage. In this way, it is impossible for hackers to hack everyone's personal data and then use some encryption algorithms, In the blockchain, it can really protect personal privacy and make very good calculation

artificial intelligence needs data, but data is often monopolized by centralized platforms, which hinders innovation. Encryption economics creates a data market with correct incentive mechanism for data providers, and artificial intelligence can take off on this data market. In a fair data market, the value of data is measured by cross entropy. In our society, some minorities will be discriminated against. However, in the encrypted data market, the data they provide will receive the most attention. Encryption economics can offset all kinds of prejudices in current social economics

blockchain is a direction of technology. Technically speaking, how much value blockchain can have is still a question mark, which may have great value, but today, the application has not been implemented. We don't deny the value brought by blockchain. In terms of technology, I think it is very valuable and promising, but no one can know how big the prospect is

in the financial field, blockchain is absolutely subject to supervision and is not a free world. Political orientation should be correct. In the field of blockchain, we should adhere to the leadership of the party and accept supervision. digital currency can not be anarchism, it needs the correct guidance and supervision of the government

now we all focus on the real economy, whether it's entrepreneurship or investment. I think the blockchain itself should create value. If a company issues a coin and doesn't know what to do, it will suddenly be worth tens of billions of dollars, which is completely divorced from value creation

as for the title of classical investors, it's just a joke, or to grab an eye and create some concepts. I believe that 99% of the projects or 95% of the projects will be done by classical VC in 2018

blockchain is very popular, but in fact, institutional investors participate very little. At present, many of them are indivial behaviors. More than 95% of ICO in China is money making, and the really large first-line institutional investors actually participate very little. To be honest, these people can become first-line institutional investors. They are not fooled. They know more than you, see more than you, and read more books than you. How can they be so stupid? They make money from people with lower IQ than you

Wu Ying, chairman of the digital China Federation:

pays close attention to the blockchain and has made a certain investment layout here. Among the three or four companies invested, there are 13 patents. Among the listed companies previously invested, 2 are doing blockchain business. However, it will take some time for blockchain to break out. On the whole, it will take about three years for blockchain to have a direct impact on the economy, but it may be faster than the United States in some aspects. Focus on the application of right protection of works of art, and set up an angel fund to invest in blockchain in the future

talk about big data: the obstacle of data exchange lies in the system rather than technology

Wang Jian, chairman of Technical Committee of Alibaba Group:

data is the material basis of digital economy. Data can neither be shared nor opened, but the value of data can be shared. Uber and didi are great changes in human behavior. What have they changed? In fact, Uber and didi are not sharing cars. In the past, they came out from home in the morning to tell their parents where to go. But with Uber and Didi, you can actually share with a company about where to go today. This is the real change

Guo Wei, chairman of the board of directors and chairman of Digital China Holdings Co., Ltd.

from the perspective of the government, he highly recognizes the value of data, but it is very difficult to implement it. Data itself has a natural segmentation, different people have different cognition of data. Another very important point is the division of interests. Due to the huge benefits brought by mastering the data, some people are not willing to release them. If released, it means the loss of privileges, which is the most difficult part in the process of data access today

from the perspective of today's technology, there is no problem to achieve data access with our technical ability, whether it is traditional technology or the latest developed technology. But the most important obstacle is the system

Yan Yan, founding managing partner of Saifu Asia Investment Fund:

the opening of data is a double-edged sword, and social data should not be open to everyone, because data is useless to more than 95% of people, and there are less than 1% of people, so it is harmful to the society to give them data

Blockchain itself is not illegal, but if it is used illegally, it is illegal

Li Bin, deputy director of Chongqing big data application and development administration, said that as a disruptive innovative frontier technology in the field of big data intelligence, the Chongqing municipal government attaches great importance to active layout, and the municipal government and Yuzhong District Government jointly build a blockchain base. In the second half of last year, the government issued the opinions on accelerating the cultivation and innovative application of blockchain instry, It has officially launched the construction of a place for strategic innovation of blockchain

while actively encouraging the technological progress and instrial development of blockchain, we will resolutely prohibit the illegal use of blockchain technology in accordance with the requirements of relevant national policies

at present, China's blockchain technology and application continue to innovate, and are graally applied in supply chain finance, credit reference, proct traceability and other fields, with huge development space. As a new technology, if blockchain wants to realize large-scale practical application, it must strengthen the cooperation of instry, University, research and application, and promote the continuous development and maturity of technology and application

since 2017, the development of blockchain technology has aroused the deep concern of the government, enterprises and other sectors. Because of its decentralized, tamperable and traceable characteristics, blockchain attracts investors to add weight to this new technology field. For the previous hot speculation of blockchain technology, the cognition of it and investment circles has become increasingly rational

According to experts, blockchain can be understood as a distributed public ledger, which is connected by various blocks into a chain. In the traditional bookkeeping system, the bookkeeping right is controlled by the central server

on the "account book" of blockchain, every point in the chain can record information on it, forming a point-to-point accounting system. Therefore, blockchain technology is considered as a decentralized technology

with the blockchain system, Zhang San can directly record his 10000 yuan to Li Si's account book, and the transaction information will be transmitted to the whole village, that is, the whole blockchain system, so that other 98 people can see the information. The whole transaction process is recorded by the system, which has the advantage of traceability to prevent the loss of Zhao Liu's account book or Li Si's denial of account

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain became the core component of electronic currency bitcoin: as a public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently

the blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. The design of bitcoin has become a source of inspiration for other applications

Load the coin and go overseas! Over the past few months, this seems to be the most popular topic among the smart minds in the currency circle

indeed, after the relevant ban, the innovators of the currency circle began to participate in the research of "currency" trading and "agent investment and private placement" and other hedging means, and made great achievements. However, this has not restrained the pace of many exchanges and money circle tycoons moving overseas, and the Machiya houses in Kyoto, Japan, and the cryptocurrency company registration applications in Minsk (the capital of Belarus) have also gone up

as soon as anything gets hot, the cost of all aspects will increase. So more intelligent people began to focus on Africa, an ancient and mysterious land

people always believe what they want to believe, even ignore the facts. From the current point of view, Africa should have a long way to go from the title of "blockchain center". If you want to go gold panning, you must think twice

we analyze it from four aspects:

the concept of management department is rigid

Cape Town is the second largest city in South Africa, which is famous for its beautiful natural landscape and wharf

just recently, a "blockchain Research Institute" was quietly established in Cape Town. According to media reports, the blockchain research institute does not do academic research. Its main work is to provide training services related to blockchain technology to some local start-ups. According to its insiders, they not only provide training services, but also provide blockchain consulting services to enterprises

in addition, the blockchain Research Institute has also carried out close cooperation with local financial institutions, including the Bank of Africa, Standard Bank of South Africa, etc. Interestingly, some managers of these banks have received relevant training in the "blockchain Research Institute"

in fact, this blockchain Research Institute is a very common ecational institution, and it is profitable. Its teaching ability is questionable. More importantly, there is no university offering blockchain related courses on the African continent, and there is no corresponding supply of blockchain talents. The vast majority of the people still know little about blockchain

in developed countries, blockchain courses have been implemented in Colleges and universities. According to incomplete statistics, dozens of universities such as Princeton University, Tsinghua University, Stanford University, Copenhagen University, MIT, Imperial University of London, Cambridge University and New York University have offered blockchain courses

if ecation can't keep up with it and there is no large supply of talents, the construction of instry will be inadequate. For the road of blockchain in the African continent, talent is a top priority

worrying about infrastructure

when it comes to blockchain, mining is an inevitable topic. Mining requires a lot of power consumption. The S9 miner usually consumes 1350 watts of power ring operation, which is equivalent to exhausting the life of a hair dryer

according to a research result of an organization, the cost of mining in Africa is the lowest, and the average cost of digging out a bitcoin is $4626. The rest were South America (US $5456), Middle East (US $6249), Asia (US $6378) and Europe (US $6695)

does this mean that digital currency mining can be carried out on a large scale in Africa

The Research Report "people, power, planet" released by the African development group tells us the answer from the side: in Africa, one out of every three people has no electricity. According to the total population of Africa, about 621 million Africans have no electricity. According to its development trend, it will not be until 2080 for Africa to realize the power popularization of the whole continent. In terms of grid capacity, sub Saharan Africa is about 90 megawatts, which is even lower than South Korea, which has a fifth of its population

although the electricity price is cheap, the future of blockchain's large-scale implementation is unknown when the backward infrastructure has not completely rid the public of the problem of power shortage
