The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware

the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient

Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card

mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards

bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper

extended data:

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

4. Don't think about mining. When you install the miner, the price may drop. As a whole, the electricity bill for one day is not enough. Mining machine, then at least 6 cards to have effect, the previous hd7850 speed is difficult to get a bitcoin a month!

5. Lidar is a kind of remote sensing measurement which uses laser as light source and detects the light wave signal without interaction between laser and detected. The lidar technology using vibration Raman technology is Raman lidar, which is mainly used for atmospheric remote sensing measurement. Raman lidar is a kind of remote sensing technology. As an active remote sensing detection technology and tool, lidar has a history of nearly 50 years. At present, it is widely used in Earth Science and meteorology, physics and astronomy, biology and ecological conservation, military and other fields. Among them, the traditional lidar is mainly used for land vegetation monitoring, laser atmospheric transmission, fine weather detection, global climate prediction, marine environment monitoring and so on. With the rapid development of laser technology, fine spectroscopic technology, photoelectric detection technology and computer control technology, lidar has unique advantages in remote sensing detection height, spatial resolution, time continuous monitoring and measurement accuracy
lidar is a radar system that detects the position, velocity and other characteristics of the target by emitting laser beam. In terms of working principle, there is no fundamental difference with microwave radar: transmitting the detection signal (exciting beam) to the target, and then comparing the received signal (target echo) reflected from the target with the transmitted signal, after proper processing, the relevant information of the target can be obtained, such as the target distance, azimuth, altitude, speed, attitude, even shape and other parameters, so as to realize the target detection Missile and other targets are detected, tracked and identified. According to different detection technologies, lidar can be divided into direct detection type and coherent detection type. According to different functions, it can be divided into tracking radar, moving target indication radar, velocity measurement radar, wind shear detection radar, target recognition radar, imaging radar and vibration sensing radar
the working principle of lidar and radio radar is basically the same, and depends on the detection technology used. The basic structure of the direct detection lidar is quite similar to that of the laser rangefinder. When working, a signal is sent by the transmitting system, which is collected by the receiving system after being reflected by the target, and the distance of the target is determined by measuring the round-trip propagation time of the laser signal. As for the radial velocity of the target, it can be determined by the Doppler frequency shift of the reflected light. It can also be obtained by measuring two or more distances and calculating the rate of change
coherent detection lidar can be divided into monostable and bistable. In the so-called monostable system, the transmitting and receiving signals share one optical aperture and are isolated by the transmitting receiving switch. The bistable system consists of two optical apertures for transmitting and receiving signals respectively. The transmit receive switch is no longer needed, and the rest is the same as the monostable system
lidar is a combination of laser technology and radar technology. It consists of transmitter, antenna, receiver, tracking rack and information processing. The transmitter is a variety of lasers, such as CO2 laser, Nd doped yttrium aluminum garnet laser, semiconctor laser and wavelength tunable solid-state laser; The antenna is an optical telescope; The receiver uses various types of photodetectors, such as photomultiplier tubes, semiconctor photodiodes, avalanche photodiodes, infrared and visible multi detector devices, etc. Lidar uses pulse or continuous wave, and the detection methods include direct detection and heterodyne detection
weather radar is a kind of radar specially used for atmospheric detection. It belongs to active microwave atmospheric remote sensing equipment. The high altitude wind radar, which is used with radiosonde, is only a kind of special equipment for positioning displacement balloons, and is generally not regarded as this kind of radar. Weather radar is one of the main detection tools for warning and forecasting medium and small-scale weather systems (such as typhoon and rainstorm clouds). It works in the frequency band of 30-3000 MHz. Generally, it has high detection sensitivity. Because the detection altitude range can reach 1-100 km, it is also known as the middle stratosphere troposphere radar (MST radar). It is mainly used to detect the vertical distribution of atmospheric dynamic parameters such as wind, atmospheric turbulence and atmospheric stability in clear air
the initial interest of the U.S. Department of defense in lidar is similar to that of microwave radar, that is, it focuses on target monitoring, acquisition, tracking, damage assessment (satka) and navigation. However, because the microwave radar is enough to complete most of the damage assessment and navigation tasks, the military lidar plans to focus on a small number of tasks that the former can not complete well, such as high-precision damage assessment, extremely accurate navigation correction and high-resolution imaging. In military, it is often hoped that the aircraft can fly at low altitude, but the minimum altitude of the aircraft is limited by the ability of sensors to detect small obstacles. Not to mention blocking the balloon line and other confrontation facilities, under 60 meters, all kinds of power lines, high-voltage lines, towers, masts, antenna cables and other small obstacles also have obvious dangers. The existing aircraft sensors, from human eyes to radar, are difficult to detect these dangerous objects in advance, especially at night and in bad weather conditions. Because of its high angular resolution, scanning lidar can form effective images of these obstacles in real time and provide appropriate early warning
lidar can be used to measure the trajectories of various flying targets in military. Such as the tracking and measurement of the initial phase of missile and rocket, the tracking and measurement of aircraft and cruise missile at low elevation, the precise orbit determination of satellite, etc. The combination of lidar with infrared, TV and other optoelectronic equipment forms ground, shipboard and airborne fire control systems to search, identify, track and measure targets. Because lidar can obtain the three-dimensional image and velocity information of the target, it is helpful to identify the stealth target. Lidar can monitor the atmosphere, telemeter the pollution and poison in the atmosphere, and measure the temperature, humidity, wind speed, visibility and cloud height of the atmosphere
the traditional way for marine lidar to alert, search, characterize and track underwater targets is to use large and heavy sonar, which usually weighs 600 kg to dozens of tons. Since the development of Ocean Lidar, namely airborne blue-green laser transmitting and receiving equipment, ocean underwater target detection is simple, convenient and accurate. Especially in the third generation lidar which was successfully developed after 1990s, the functions of GPS positioning and height determination were added to realize the automatic control of route and altitude. For example, the "arms" airborne mine detection lidar developed by Northrop company of the United States can work 24 hours and accurately detect suspicious targets such as underwater mines. The underwater imaging lidar developed by American Kaman space company has more advantages. It can display the shape and other characteristics of underwater targets, accurately capture targets, and take emergency measures to ensure navigation safety
in addition, lidar can also be widely used to counter electronic warfare, anti radiation missiles, ultra-low altitude penetration, missile and shell guidance, and land mine sweeping.

6. First of all, we analyze the development of China's economy from the perspective of GDP. The GDP is national purchase + government purchase + investment + export import. Since the reform and opening up, China's GDP growth has been mainly driven by investment and export, and the proportion of export stations is larger. In recent years, China's frequent investment and construction of large-scale projects mainly rely on government purchase as another driving force for development. Due to the deformity and bias of domestic instrial structure, national purchase has not been the main economic driving force. China is the country with the highest degree of foreign dependence in the world (the ratio of international trade deficit to national income). According to the textbook, it accounts for 70% (I think it should be only 40% at most), which is nearly twice as high as Russia, the second highest country. Therefore, e to the high degree of foreign dependence, the market main body of made in China is not at home, It has caused the deformity of the national instrial chain Most of the exported nails, steel, can't encourage the public to buy them home, and can't eat them In order to get rid of this dilemma, the government has been calling for the expansion of domestic demand, because the annual trade deficit makes China hoard too much foreign exchange... Ordinary people can't use US dollars to shop in their daily life at home, so the money can only be exchanged by the state treasury in the end.) coupled with the foreign "mping" lawsuits against China and the emergence of trade barriers, the weakness of excessive dependence on foreign countries has begun to hurt China's economy. Economic transformation is not easy. First of all, you have to make rational use of the surplus proction. At this time, the most useful real estate appears, and an investment target that can pull more than 30 instries by itself appears. In addition, land development and auction have become a large part of local government revenue, Therefore, the state vigorously supports (there are many forced demolition problems). But with the passage of time, the overheating of real estate also involves financial instability. When real estate is no longer a necessity but a speculative investment, it will eventually become pure concrete rather than stable repayment ability (whether it is building or buying a house, most businesses and indivials are through loans or mortgages), China's "subprime" crisis began to break out. In fact, according to the theory of western economics, it may be a miracle that China's real estate did not cause China's economy to collapse now, but the state's macro-control and slow weakening of real estate development have indeed played an incomparable role. With the development of economy and the improvement of employment rate in our country, people are happy to see that our GDP is developing at a high speed of 10% every year, and we are jubilant to become the second largest economy in the world. At the same time, we have encountered three headache problems
first, China has become the world's creditor. The foreign exchange reserves of 200 billion US dollars mean that China has more US dollar cash in its treasury than the United States. When its economy goes wrong, it will reach out to China and borrow it. It will return it, but it is just fresh money directly from the banknote printing machine. So what's the difference between the fresh banknotes and the old banknotes? The difference lies in their depreciation and sharp decline in purchasing power. We can think that they originally had 100 cattle, issued 1 million US dollars, and China had 100000 in its pocket. At this time, 10000 US dollars is a cow; Later, the United States and China borrowed the 100000, and when they returned it, they printed another 100000 US dollars to China, but only 11000 US dollars could buy a cow at that time, so they cheated us... Then we can't borrow it. Your loss in China is even more miserable. If I don't lose a dollar against your RMB, you will lose 200 billion RMB. Can you afford to lose? So China had to help him. In this way, China should be very passive. But last year, our leaders began to use US dollars to inhale a lot of gold, turning piles of waste paper into lovely, gorgeous and golden gold. Although we have got rid of the fixed exchange rate system, the stability of the value of gold is far higher than that of paper money. Therefore, comrades, Get some gold before we run out of dollars... At least I made a small profit from my gold
Second, the rapid economic development and high employment rate bring about high inflation rate. With the increase of inflation rate and CPI, more and more people work and have a stable income. Moreover, the income graally increases, and the rise of prices can not be avoided. I still remember that when I was in junior high school, a finished noodle at my home only sold for 3.5 yuan. This time I returned home and asked for 6 yuan. God... Compared with the rise of the exchange rate, it's a good choice for everyone to study abroad. Therefore, how to control the priceless rise and stabilize the inflation is one of the main problems of China's economy in the next step, and this environment also urges us to prepare to invest abroad (we can also be foreign enterprises in foreign countries). Of course, it is not necessarily the European and American powers, but the relatively backward but resource rich small countries, such as Myanmar, Laos, Cambodia, Vietnam and other Southeast Asian countries, whose economic situation and resource utilization rate are very similar to those of China in the 1980s and 1990s, are also encouraging foreign investment. Our great motherland saw such an opportunity, so it vigorously developed the Southwest (this is related to the third issue), established bridgeheads, laid the Pan Asian Railway and so on, and achieved initial results, such as vegetable oil exchange in Yunnan and Thailand, China and Thailand free of fruit and vegetable tariffs and so on... Because I'm here
thirdly, the gap between the rich and the poor is too large, the utilization rate of resources is low, the utilization of resources is unreasonable, etc.
the rapid development makes some people richer and some people may be poorer. To some extent, we have no conscience can be called the law of the jungle, but we can also have a conscience to say that many rich people are not benevolent. This seems to have nothing to do with economy, but it is closely related to social stability and political strength. If these two points are gone, what we can consider is to escape from the country or resell arms to make a fortune. The first to become rich should be those engaged in import and export (both legal and illegal), then those engaged in mining, and those engaged in real estate recently. Here we want to see the times and the conditions for them to become rich. Import and export have just started the reform and opening up. Whether it's the low price of Chinese made goods or the curiosity of Chinese people about foreign goods, these people almost became the first to get rich at that time by using the price difference in the middle. They have a condition to get rich. They have a place to do import and export for you. For bulk logistics, trains can't go directly, Airplanes are too expensive. They can only be transported by sea... The coastal people laughed (so that up to now, some people think that apart from the coastal areas, most of the inland areas are poor, and my mother-in-law should be counted as one...), Later, foreigners found that your mine was better. All right, those who found the mine laughed. Overnight, they changed from farmers to mine owners. Some of them could not adapt to this gap, making mine owners a derogatory term today... For them, wealth and their cultural quality may not be in direct proportion, which leads to some very rampant rich second generation XX. Mine boss mine boss in the final analysis, you have to find your own mine, or you are likely to be a miner... Therefore, it is necessary to have regional characteristics. Finally, when it comes to real estate, it's finally a bit balanced, at least not regional, but you still need to have "resources". Although some of their black hearted people are still poor, from the perspective of economics, I would like to pay tribute to them, because economy is the rational use of all resources to maximize, they not only use the funds, technology, human resources, but also "contacts" resources, Finally, it also affected the economic situation and financial trend of the whole country. A few people own resources, and they don't share all the resources with everyone. Therefore, the gap between the rich and the poor is graally widening, causing a series of problems. In Thailand, the rich people donate money to temples every month, buy things to temples, and then distribute them to the poor and the needy. In addition, temples actively build schools and really achieve compulsory ecation (I was a teacher in Temple schools), I hope the rich in our country can do the same. It's not economics, it's sociology, but I'm still itching to say, remember that the founding of the people's Republic of China was e to grandfather Mao's fight against local tyrants and division of land, be careful of his reincarnation
China's national strength is becoming stronger and stronger, and the strong economy has also brought us a happy life, although the economic system still has many disadvantages (such as buying bonds, not to mention making profits, even losing the principal... But I think with the development of the times, China will only become more and more powerful (if we don't become the second Song Dynasty in history, and find the time to beat those Filipinos who say we Chinese are small eyes every day). God bless China
I have little talent and little learning. I dare to talk about China's economy. If there is something wrong, please correct it and communicate with my friends. If the landlord adopts my question, I would be very grateful

virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" is popular in the circle

network virtual currency can be roughly divided into

[1] the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency

[2] the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services

[3] the third kind of virtual currency on the Internet, such as bitcoin (BTC), lightmoney (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency

[4] the application of computer communication technology and the development of Internet as a new media are the technical basis of network marketing. Internet was born in the 1960s. With the development of network protocols and related hardware and software procts, Internet has graally changed from military to commercial and civil. From the 1990s, the Internet has graally entered into the daily life of society. As a matter of fact, the Internet, as an emerging media, has developed faster than all other technologies in the past. It took 38 years for radio to reach 50 million audiences, 13 years for television, and only 3-4 years for Internet. Therefore, the Internet is considered to be the technological change that has the greatest impact on the world economy in the past 100 years

8. Hello,

would you like to choose a mining machinery trusteeship company with the mine located in Hunan, or a company with the mine located in Hunan and the mine located elsewhere
Hunan Province is located in plain and hilly areas, and neither hydropower nor thermal power generation is the best area, so it is not a low-cost province
it is recommended that you choose the provinces in Northwest and southwest, where the geographical location is large, the water resources are rich, or the coal mines are rich, and the thermal power generation is cheap
if you have any idea, please contact me in private. Our mine is located in RUOJIANG, Xinjiang. I hope I can help you. Thank you
