The wealth myth of "one coin, one villa" is still widely spread in the currency circle, and new investors are eager to try. But in fact, a stable power structure has been formed in this small circle, from mining machinery manufacturers to large mine owners, and then to mining pools

manufacturing and selling mining machines, mining, building mines and building ore pools, the "mining circle" has become another way to get rich in the blockchain world, and mining machines have also become a little-known "big business"

according to the imagination of Nakamoto, the inventor of bitcoin, the ideal state should be "decentralized", with computing power scattered all over the world. However, contrary to decentralization, the mine pool is absolutely centralized, and more and more mining machines are connected to the mine pool

"if speculation is a road of no return, then investment in mining machinery is a business that can make a steady profit without loss, and it is only a matter of time before the cost is recovered." Zhong Xi, general manager of Shenzhen Aibo times Technology Co., Ltd., calculated an account. A miner earns 200 yuan a day, which can be recovered in 120 days, and then the profit

in October 2017, in addition to his main business, Zhong Xi joined the mining army and quickly became a big boss in the mining circle. He operated many large mines in Jiangxi, Sichuan, Guizhou and other places

in fact, the business of "steady profit without loss" still depends on the continuous rise of currency price. In the past two months, the price of bitcoin has dropped from US $15000 to about US $10000, or even below US $6000 at one time, which has extended the cycle of mining machinery return. If it keeps falling, the profit will be far away

in 2012, four years after the advent of bitcoin, mass-proced mining machines appeared. Before that, mining was mainly a private activity, which could be completed by a home computer“ At that time, the home computer was the money printing machine, and a lot of bitcoin could be g up every day. " Huang Shiliang, a senior digital currency player who sold mining machines in his early years, recalled to Southern Weekend reporters

after the emergence of mining machine, mining began to be "socialized", with the emergence of mines and pools, and mining became a collective work. The indivial miner is entrusted by the mine, just like the workers on the proction line, as long as they are there, they can get paid every day

manufacturing and selling mining machines, mining, building mines and building ore pools, the "mining circle" has become another way to get rich in the blockchain world, and mining machines have also become a little-known "big business"

China has become the world's largest procer of mining machinery. Since 2012, a number of miner manufacturers have been born in China, such as Shenzhen bitquan Co., Ltd., which proces cat roasting miner, bitmainland, Jianan Yun and Yibang communication, which are now famous. In Huaqiangbei, Shenzhen, foreigners can be seen everywhere asking about the price of mining machinery with translators

recently, in an interview with the media, the CEO of bitcontinental, Mr. Zhan Ketun, said that this startup company, which has been established for only four years, had a revenue of about US $2.5 billion in 2017. Bitcontinent is known as the world's largest miner, whose ant miner has always been the hard currency of the coin circle and miner world

just like the coin circle, the mining circle also needs belief that the mechanical mathematical operation of mining machines every day can create great wealth

However, contrary to the "decentralization" advocated by bitcoin, the miner's world is moving towards "centralization". Miner dealers build their own mines. After the investors buy the miner, they are entrusted by the seller; The procers build their own mines and manage them

this process of "centralization" made the wealth of the mining circle snatched by a few people, and it was not easy for Zhong Xi to enter the core circle

calculation force "centralization"

the main function of the mine is to provide a place for scattered mining machines to operate. But it is the "ore pool" that really plays the role of integration

the so-called "mine pool" can be simply understood as "cooperative mining". The miners and the mines give the calculation power to the mine pool, and the mine pool is used as the only address to access the digital currency network for mining, and then distribute dividends to the miners according to the calculation power of the mining machine

the history of ore pool is longer than that of mining machine. In November 2010, the mine pool named slush appeared. Today, its official website says "the world's first mine pool", which is also recognized by the coin circle. Compared with the mine, the construction of the mine pool needs certain technology, and the threshold is relatively higher

the person in charge of a well-known domestic mine pool explained the principle of the mine pool to the Southern Weekend reporter. He compares mining to buying lottery tickets. If you dig alone, the probability of winning the lottery is very unstable. You may win 100000 today, but you won't in the next six months

"gather the people who buy lottery tickets together and buy them in a unified way. No matter who wins, they will be divided according to the proportion of money they pay. In the coin circle, the mine pool plays this role. " The person in charge said

it's not complicated to connect the mining machine with the ore pool. According to the operation guidelines of the major ore pools, it can be completed in a few steps, and then according to the calculation power provided by ourselves, we can get benefits from the ore pool. The miner is like a worker standing on the proction line, receiving a fixed salary every day

the mine pool with huge computing power and many mining machines has an absolute say in the coin circle and the mining circle. For example, if you want to issue a new digital currency or dominate the bitcoin bifurcation, you generally need to get the support of the mine pool. Without the support of the mine pool, no one will dig the new currency, so it is meaningless

in addition, when a hot new coin comes out, the mine pool can also use its own miners to pack it quickly and take the lead in the rush purchase of these new coins

in June 2017, when SNT and EOS were issued, Southern Weekend reporters witnessed the scene of minchi snapping up tokens. Because there are too many investors, many indivial investors can not put their funds into the designated position, but the person in charge of a mine pool can easily complete this operation

according to the imagination of Nakamoto, the inventor of bitcoin, the ideal state should be "decentralized", with computing power scattered all over the world. However, contrary to decentralization, the mine pool is absolutely centralized, and more and more mining machines are connected to the mine pool

on January 18, 2018, Emin Yun silash, a computer professor at Cornell University, and other five people co authored a paper pointing out that there is an implicit power structure behind bitcoin and Ethereum, the two major digital currencies, and mining is too centralized, in which 50% of bitcoin's computing power is controlled by the four major mines

In fact, this problem has always existed. Four years ago, the founder of Ethereum, vtalik, noticed this problem when he wrote Ethereum white paper. He wrote: "this problem can be said to be very serious. At the time of writing this article, the two largest mines indirectly controlled about 50% of the computing power of the whole network."

Up to now, this problem has not been solved. An early translator of the Ethereum white paper told the Southern Weekend reporter, "this is not a technical problem, but a human problem."

recessive power structure

in the mining circle, the top of the food chain is mining machinery manufacturers. At present, the three recognized mining machinery manufacturers are located in China. Through the proction and sales of mining machines, they get a lot of profits. At the same time, they also set foot in the construction of mines and pools, and have the right to speak in the whole coin circle

ant mining pool is one of the top two large mining pools in the world, and its computing power accounts for 17% of the total network computing power. However, according to instrial and commercial data, it was founded by bitmainland; Several investors of Jianan Yun are also investors of Hangzhou mining Pool Technology Co., Ltd., which has its own mining pool hash and mining platform, but the mining pool has ceased operation at the end of 2017

Yibang communications has set up three blockchain companies in Hohhot, Wuhai and Zhundong Economic Development Zone in Inner Mongolia. A salesperson of Yibang communications told reporters at Nanfang Weekend that they have mines and mining businesses in these three places, but these mines have been operating at full capacity, and there is no machine space to host new mining machines

"we are building a new mine in Irkutsk, Russia, where electricity charges are much lower and new mining machines can be hosted there." The source said

above the mining machinery manufacturers, it is the harvest of chip giants“ The core technology of mining machinery lies in the chip. Whoever has the chip can proce more mining machinery. " Ding Yang told reporters at Nanfang Weekend that the chips are mainly in the hands of several giant manufacturers, such as TSMC, NVIDIA, AMD, etc

since 2015, TSMC has always been the largest chip supplier of Jianan Yun. In 2015, the chips purchased by Jianan Yun from TSMC accounted for 69.62% of all the chips purchased by Jianan Yun. Since then, this figure has been maintained at about 60%. Most of the profits of Jia Nan Yun Zhi were made by TSMC

On January 18, 2018, at the presentation meeting of TSMC's fourth quarter financial report, chairman Zhang Zhongmou said that although the mobile business prospect this year is weak, the company's revenue will still grow by 10% - 15%. One of the key factors is the demand for chips e to the continuous and steady development of cryptocurrency

under the mining machinery manufacturers, there is another power structure. Jianan Yun disclosed this secret in its 2017 prospectus. In the first four months of 2017, four of the top five customers of Jianan Yun were "indivials". According to public information, three of them are well-known "wrists" in the currency circle

Wu Gang, the largest customer, was the first group of miners, and later founded haobtc, which has one of the world's top ten mines; Lin Zhipeng, the second largest customer, is the founder of Xiaoqiang mining machinery. He has been engaged in the proction and sales of mining machinery for a long time. He has been cooperating with Xie Weiqin, the sixth largest customer; Wang Jin, the third largest customer, founded bitbang, a coin circle information website

these big customers are not simple miners, they all have their own influence in the coin circle. Mechanical operation of the mining machine to bring them income at the same time, also brought the right to speak

according to an insider in bitmainland, most of the big customers in bitmainland are big guys in the currency circle. However, bitmainland officials declined an interview with the Southern Weekend reporter. The company's Public Relations Department responded that it was not convenient to disclose the content because it signed a confidentiality agreement with its customers

"one coin, one villa" wealth myth is still widely spread in the currency circle, and new investors are eager to try. But in fact, a stable power structure has been formed in this small circle, from mining machinery manufacturers to large mine owners, and then to mining pools

most of the new entrants can only make the harvested "leeks"

2. Of course, you can mine, but you have to mine what only computers can. Otherwise, compared with professional mining machines, office computers have no advantage at all. You can mine what only computers can. For example, ITGC is about one yuan now
the most important thing is that ITGC client has built-in one click mining! One click mining! One click mining! Important things are to be repeated for 3 times. For Xiao, in fact, mining is not so difficult, as long as there is a computer, a mobile phone can, today teach you a key mining
first of all, we need to download ITGC's wallet client. We can search eppool, Download professional mining tools, and now support PC's win, Linux, MacOS's CPU and graphics card mining, as well as Android mobile phone mining! The second step is to download the official wallet client. After downloading and installing, we start ITGC wallet. Step three, start mining Mining command] enter go and enter to start your mining journey. It's so simple! It's amazing!

3. Under your network, ha Yu miner, this mining software has 24-hour estimated revenue, you can see

4. Use gpu-z to measure the parameters and compare with the official website

5. Mobile phone games, mobile phone kits,
battery maintenance. If you find more new battery managers, install battery housekeepers after downloading, there are many power saving modes to save the power of mobile phones, and the intelligent dynamic adjustment of CPU frequency can save energy and power, and maintain the function of charging. It can save charging time, rece power consumption and prolong battery life in three different charging stages.

6. As far as possible, offices should be set up near the mining areas, such as coal mines, iron ores, lead-zinc mines, which are mainly distributed in the Far East and East Siberia of Russia. Just like XCMG set up an office for shensk in Prague, Amur state. It's like a talent show. If you don't come out to compete, people will know who you are? The price of setting up an office in Russia is not very expensive, even lower than that of setting up an office in Beijing, Shanghai and Guangzhou. The rent of the office is 2000 yuan per month. The price of food is cheaper than that in China, and the cost of communication is lower than that in China. As long as you have Chinese people to buy your equipment and use it in Russia, your market will open. The main reason is the price. Russian people also have mining machinery, such as ural mining machinery factory, It's the place where Jiang Jingguo used to work. If your price can't be lower than other people's, you can stay in China.

7. 1. For small and medium-sized concentrators with fewer grinders, the vertical configuration scheme (the center line of the mill is perpendicular to the center line of the powder bin) is generally adopted. The main advantages are easy to operate, easy to pulp from the mainstream and pulp distribution
2. The length of grinding span should be adapted to the separation span. If the separation span is too long, parallel configuration can be considered
3. The grinding machine of multi-stage grinding can be configured in the same bay or in two bays. The advantages of two span configuration are simple process and few circuits, but when there are not many grinders, it is more economical to configure in one span
4. The angle of belt conveyor used for grinding machine feeding should not be too large, generally less than 18 °， The receiving point of the feeder should be stable, and the captain depends on the installation requirements of the electronic scale. In order to ensure the accuracy, it is better to use the tail of the heavy hammer to tighten the belt to maintain a certain tension
5. Crane capacity shall be selected according to regulations. When multiple cranes are used e to the large number of mills, the double deck layout method should be avoided to rece the height of the plant
6. The special maintenance equipment should be selected according to the requirements of the manufacturer. The grinding machine with a diameter of more than 5m should generally be equipped with a special manipulator, and there should be enough space and area in the configuration
7. When grinding across the surface, enough slope should be maintained, generally 5-10%, and good sewage and sand discharge systems should be set up to meet the requirements of environmental protection and rece metal loss
8. Due to the large noise in the workshop, the relevant offices, living rooms and automatic control rooms should be arranged far away from the sound source, or appropriate sound insulation measures should be taken
9. The steel ball warehouse should be located near the maintenance site, and the transportation convenience should be considered in combination with the terrain. In order to improve the condition of ball cleaning, a waste ball bin should be set up on the maintenance site to facilitate the transportation of waste balls by truck
10. The area of the maintenance site shall be selected according to the provisions of this manual. The gate of the site shall be consistent with the external transportation conditions. The specifications of the gate shall meet the installation and transportation requirements of grinding machine parts and components. When the overall size of the equipment is large, the installation hole should be reserved

8. Responsibilities of mechanical and electrical department, safety responsibility system of each post (section chief, deputy section chief, chief engineer, etc.), and relevant business processes of your mine's mechanical and electrical department

9. Duan Jiaxuan, a research fellow in the machinery instry of CIC, pointed out that the construction machinery market in the second quarter was in decline, and the market was looking forward to the acceleration of affordable housing construction in the second half of the year. From the current construction progress and current situation of affordable housing in the market, there were mixed feelings. Benefited from the sustained and rapid growth of China's real estate and infrastructure investment, the growth of concrete machinery exceeded expectations, which once again highlights the inertia of China's relying on heavy instry to drive economic growth still exists

as an important part of construction machinery, the huge demand space of the market and the rapid development of the instry promote enterprises to continuously accelerate investment. With the acceleration of market investment, the competition between enterprises is also increasing. At present, the investment in the market tends to be irrational, and the market is still worried. On the basis of the decline of infrastructure investment, despite the bullish worries, the investment growth of leading enterprises has not decreased at all

according to the "2011-2015 China machinery instry investment analysis and prospect forecast report" released by CIC consultants, in the fierce market competition, market expansion is undoubtedly the common competition mode adopted by all enterprises. The market is in an accelerated state, and the competition is also accelerating, and there is a growing trend. The entry of Shantui and Liugong, together with the expansion of XCMG's concrete machinery instry, will form a direct competition with Zoomlion and Sany Heavy Instry, which have been dominating the concrete machinery instry for many years< According to Zhang Yanlin, research director of CIC, mining machinery is still a promising sub instry. The growth of mining equipment instry mainly depends on the investment in infrastructure construction. Due to the rapid development of China's economic construction, there are still many projects, including roads, railways and real estate. In the future, the development of mining equipment instry will continue to increase, The infrastructure investment kept at a certain level will become the main growth power of mining equipment instry in 2011.
