What are you looking at in mining

1.

I also use almost all the mining software on the market. Many of them say they don't smoke, but I actually smoke them, and the highest one is even 20% (this friend told me that I didn't use a certain software myself)

the number of old miners has increased graally from a few to now. I recommend Marvel Moore for the large ones. It's really tiring to have no disk and one by one if the disk drops. No, look at the income chart

Mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

3. Mining mainly depends on the graphics card, because mining is the graphics card in the calculation, not the CPU in the calculation. Of course, it has something to do with the motherboard. There are several major requirements:
1. Six PCI-E slots are provided to connect six graphics cards

2. BIOS optimization, which can be identified by inserting 6 cards, does not need manual adjustment
3. Stable operation and unstable motherboard may cause automatic restart and shutdown, affect efficiency, or cause short circuit graphics card burn out
at present, B250 / B350 mining motherboards are mainly promoted in the market. Some new ones are very interesting, such as 7 cards / 8 cards. However, these schemes have not yet passed the test. There may be unstable factors, and some of them are not in stock. In fact, the previous 8 series are more suitable for mining. The ms-b85-btc made by the furniture factory is a very good mining board. After years of mining scheme verification, 6 PCI-E, BIOS automatic identification, and PCI-E voltage stabilizing capacitor design are added. The mining is stable, and the shutdown cost is low.

Mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

shortcomings

first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

7. As "yuan Datou" is graally recognized by the collection market, many counterfeiters forge or imitate "yuan Datou" in pursuit of interests, and many collectors become "yuan Datou" carelessly for the sake of "yuan Datou". Yao shuomin, former deputy curator of China Numismatic Museum and Deputy Secretary General of China Numismatic Society, provided us with some skills to identify the authenticity of "yuan Datou":

the first method is to "knock", take two pieces of silver coins, hold the center of one silver coin with the fingertips of both hands, and slowly draw close to each other. When the two silver coins overlap about a quarter of the position, the first method is to "knock", It makes two silver coins gently knock on each other's edge. The sound of the real coin is clear, and the sound of the fake coin sounds wooden

the second method is to "blow". Hold the center of the silver dollar gently with your index finger and thumb, blow the vertical edge of the silver dollar, and quickly put it to your ear to listen. The tail sound of the silver coin with good quality is long and clear, while other metal or non pure silver coins will not have such a tail sound. For example, the silver coin with lead in the market is almost silent, because the lead is heavier and softer, It's not easy to shake the pronunciation. Nowadays, most forgers use computer plate making and use alloy materials to pass off silver. The color and text of the forger can be confused with the real. But in the end, because it is not silver, its pronunciation is sharp and long, and experts can tell the truth as soon as they distinguish it

the third method is "weighing". The real coin is generally full weight, and its circulation loss is about 26G. Its color is soft and white, its tone is soft and long, its text and picture are accurate, and its pulp is natural; Counterfeit coins are generally not heavy enough, or overweight e to thickening, and the color is gray

Wang Jianzhong, a collector who is keen on collecting silver coins, also told reporters that his good way to identify the authenticity of silver coins is to wipe the silver coins on a touchstone several times until there are silver scratches, and then drop hydrochloric acid and nitric acid on the scratches. At this time, if it is a real coin, the mixed liquid on the scratch is milky white, and the counterfeit coin is colorless and transparent. If the silver content of silver coin is not enough, the mixed liquid of hydrochloric acid and nitric acid also appears milky white, but not rich enough. The less the silver content, the lower the richness.

Yinyuan, also known as "Yinyuan", was originally imported from abroad. Because of its uniform shape and convenient use, it is generally welcomed. At the beginning of the 18th century, the folk began to imitate, and when the local government saw that it was profitable, it took part in the unified official casting. In 1910, the Qing government issued the monetary system regulations, established the silver yuan as the national currency, stopped the free casting in various places, and took the right of coinage back to the central government. The next year, the "Qing silver coin" was coined, which created the currency circulation system with silver yuan as the unit in modern China. Silver yuan is favored by the public and collectors for its beautiful casting form and unique precious metal currency form. However, the current market is full of counterfeits, which are mainly manifested in two categories: one is the so-called "mechanism version fine imitation silver coin" with low or even zero silver content, and the other is the so-called "pure silver high imitation silver coin" with high silver content. With the continuous improvement of casting methods and the application of computer scanning technology, some of them have reached the point of confusing the true with the false. In the collection practice, the author learns from other people's experience and his own lessons, and sums up several methods to distinguish the false, which can be taught by the same good and expert< First, listening quality. The sound of the silver yuan, which contains about 90% silver, is low, soft and melodious; Counterfeits are either crisp and harsh, or ll and ll. The common feature is the short aftertone. When striking and comparing, the less the contact surface between the two fingers, the better, to ensure the effect of natural vibration. It is said that in the old days, some bank owners were lying on their chairs with their eyes closed and asked the staff to bump the silver dollars one by one into the edge of the big water tank, listening to the sound to distinguish the true from the false< Weigh the weight, thickness and diameter. These two identification methods need the help of weighing tools such as balance, scale and vernier caliper. Silver in the long-term circulation will wear and tear consumption, generally speaking, can not reach the theoretical weight, but it is not "short weight", if the Kuping Qiqian two-part edition is less than 26 grams, there is doubt. The author once bought a pair of Guangxu Yuanbao and Xuantong Yuanbao made in Hubei Province, weighing 25 grams. The result of identification confirmed that the question was correct. The standard flat code of silver coin is: Ku Ping 1 / 2 = 37.31g, Ku Ping 7 / 2 = 26.81g, Ku Ping 3 / 6 = 13.41g, Ku Ping 1 / 4 = 5.37g, Ku Ping 7 / 2 = 2.69g, Ku Ping 3 / 6 = 1.34g. The weight, thickness and diameter of silver dollar are allowed to have errors, but if there are two extremes, nine out of ten there are problems< 3. Check the edge teeth. The side teeth of the silver coin mechanism are fine, symmetrical and regular. The side teeth of the counterfeit coin are rough and uneven, and some of them have traces of local filing. As long as careful, the naked eye is still relatively easy to distinguish. Some foreign silver coins circulated in the early stage of our country, such as "Hercules of France", whose side teeth are the foreign letters with equal spacing, so we should be familiar with and master the shape of side teeth of various currencies< 4. Look at the color. Silver and non silver metals can be distinguished from each other by their surface colors. Silver has a natural and pleasant luster, which is difficult to be achieved by cheap metals. The so-called "coated slurry" of fresh water ink color will be formed on the surface of silver coins that have been stored for a long time, but it is not as heavy as ancient coins. Once wiped, it will be as old as new. The chemical molecular structure of silver is very stable and will not change color. In addition, the fake silver plating can also be identified by wiping, and the camouflage coat can be stripped by repeatedly wiping with sand rubber< 5. Coin viewing. In the sun or light, the silver coin face and the eye, observe the bottom of the coin face is uneven phenomenon. The foundry equipment used by counterfeiters is difficult to make the bottom layer of the coin as flat as a mirror. Special attention should be paid to the connection between the text pattern and the bottom layer of the coin< 6. Check the wear. After a long time of circulation, silver will always have different degrees of wear and scratch marks. The natural procers have no rules to follow. The worn-out counterfeits show the regular wear surface and scratch marks of artificial behavior and machine behavior. Some people say that the best way to make old coins is to make old coins on molds, that is, to make worn surfaces, scratches and potholes on molds. The way to deal with it is to hold a number of silver coins of the same kind and examine them one by one under a low-power magnifying glass, and "Li Gui" will show its true shape< 7. To the atlas. Keep several kinds of well printed silver dollar catalogues on hand as far as possible, and carefully compare the real objects with them. Look at the frame position of the text pattern in the large part, the stroke processing of the text and the details of the pattern in the small part, and look for the flaws

all collectors of silver coins have their own identification methods, and they have something in common

nowadays, collecting all kinds of coins and antiques has become a trend. As far as the silver coins of the Qing Dynasty and the Republic of China are concerned, there are treasures ranging from several hundred thousand yuan to several yuan worth of silver coins. There are all kinds of counterfeit coins, and the materials used are also different, which makes people unable to guard against them. The following is a list of the differences between real silver coins and several kinds of fake silver coins for reference

the real silver coin is transparent in white, soft and malleable, with clear and pleasant sound when struck, smooth layout, symmetrical edges, natural and generous pictures and pictures, and traces of circulation wear. The silver coins stored at home are hard and fine in ancient black, and those buried underground will have some irregular hard green rust. Fake black and green rust will fade away when they are soaked in boiling water, which is easy to distinguish

at the end of 1970s, the Mn Ni alloy counterfeit silver coins cast in Guangdong, Guangdong, Fujian and Hunan mountainous areas were almost all over the country. The coins were rough in workmanship, with many sand holes, containing particles, uneven thickness, light in weight, and easy to turn black for a long time. However, they could not be painted black on the lime wall, so they were the only counterfeit silver coins that would be broken. By the early 1980s, the technology of copper nickel alloy cadmium plating counterfeit coins had made some progress. There were two kinds of counterfeit coins: the picture and text were fuzzy and the three-dimensional sense was too strong. The edge teeth were basically symmetrical but unnatural, there were traces of files, there was no wear and old color coating, the sound was sharp, and the light yellow appeared after the surface was electroplated and ground off, But there are still some county stalls selling them as real silver coins

the third kind of counterfeit silver coin appeared 10 years ago. It is made of nickel zinc alloy. Its color is black and bright, and it emits lead black light. It can draw black lines repeatedly on the lime wall, and its sound is also sharp and high. It is slightly more ll than that of copper nickel alloy. Its workmanship is more realistic on one side. Although the edge of the teeth is symmetrical, it is relatively stiff. The naked eye can also see some sand holes, spots and traces of file processing, At present, this coin can still be seen in the provincial capital coin stand<

recently, there is another well-made counterfeit nickel cadmium vanadium alloy coin on the market, which has smooth layout, a little white color, a little luster, sharp sound, hard quality, a little light, too strong three-dimensional sense, less verve and file marks

the counterfeit coins pressed with real silver are the most difficult to identify. They are proced in Guangdong and Hunan in recent years. The silver quality is excellent, the color is white, and the weight is basically the same, about 26-27g. Due to insufficient pressure, the side teeth are fuzzy, the side teeth are even but unnatural, and the pictures and texts are relatively clear, but there are also some sand holes. When viewed with a magnifying glass, the patterns and characters are realistic, But the blank space layout is not very smooth, no traces of natural circulation wear and ancient color coating

another kind of common silver coin that changes and adds characters often makes some veteran forget themselves for a while, that is, common Yuan Xiang coin plus English signature version; Add "Gansu" and "Soviet" in daruijin; Sun Xiang's founding commemorative coins, such as six pointed star changed to five pointed star, English and digital misprint coins, etc. As a matter of fact, there are graphic differences between the above two editions of silver coins. The restructuring method is to first remove the surplus, then weld on some silver, and then engrave. The handwriting is a little less verve, with knife marks, and will damage the surrounding layout. After washing, it is easy to find the flaws of knife marks by painting watercolor green

there are three kinds of counterfeit coins in the Qing Dynasty and the Republic of China: first, some commemorative coins, such as Cixi, were coined out of thin air by silversmiths. The second is the counterfeit coins made later by coin workers in the late Qing Dynasty, in which a few of the coins cast in the original mould still have some value. As for the re carved and pressed coins, although they are all made of pure silver, the situation is different. After a long period of circulation, this coin has wear marks and old color paste. It can't be identified from the material and old and new aspects, so it's easy to muddle through. We can only work hard from the design and text. The third is the common silver plated copper coin in the period of the Republic of China. In the movies, it is common for businessmen to hold the silver coin with their fingertips and blow it fiercely, that is, to listen to the sound in their ears to distinguish the true from the false. Now a thin layer of silver plated copper coin has faded, revealing the basic excellent brass and red copper coins. The knock and wear are serious, which often leads to people mistaking it as a few silver mold copper samples<

the main features of several common counterfeit silver coins are introced as follows:
copperplate silver coins: its shape, size and pattern are completely similar to real silver coins, but it is mainly made of copper with rough pattern. When it is ground on a stone, the essence of copper appears, and the sound of knocking is sharp and bright with whistle
silver coin with lead: silver coin with lead inside and silver outside. Its pattern is the same as the normal silver dollar, but the sound is thick, ll, gloomy and with a click sound. When it is roasted by fire, lead will flow out
silver coin: its outer layer

In fact, in the stock market, there is no stock speculation technique of making a steady profit without losing money. In the stock market, we need to analyze the specific situation

there are basically retail investors in our national stock market. In this case, our shareholders are basically short-term operation. Short term operation can not pay attention to the development of the enterprise itself, as long as there is good news for the enterprise, the stock price of listed companies will fluctuate< our stock market will be more affected by policies, instead of focusing on the business development of listed companies. Under such circumstances, the judgment of high bearish and low bullish is certainly not good{ RRRRR}

changes in the stock market are in fact instantaneous. It's hard for us to grasp every opportunity. What's more, the more confident you are in yourself, the more miserable you may lose. Stock mentality is very important, we have to leave space for themselves. Can't, put all of their own pressure in the stock market inside
