2080 mining income

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

It's about 37 yuan

let me first introce the reward mechanism of bitcoin system

bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping

there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years

at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin

about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

0.1969btc bitcoin, which is calculated based on the mining difficulty on July 15, 2015, as shown in the following figure:

5. I use Titan XP. It looks like it's not inferior under the pressure of rtx2080ti.

6.

According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours

the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)

mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

extended data

unable to mine at home

the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine

the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages

7. Well, this configuration is not up to the level of mining at all, because now the mainstream of mining is 2080t.

1 Basic situation of exploration right distribution in Heilongjiang Province

Heilongjiang Province has formed a geological exploration instry team with state-owned geological exploration units as the main body and various economic types coexisting. By the end of 2008, there were 102 geological exploration qualified units in Heilongjiang Province. The main units of geological and mineral exploration include: Provincial Bureau of geological and mineral exploration and development, Provincial Bureau of coalfield geology, Provincial Bureau of nonferrous metal exploration, provincial administration of gold instry, Heilongjiang corps of China Building Materials Instry Geological Exploration Center, gold First Corps of armed police force, Heilongjiang Geological Exploration Institute of Ministry of chemical instry and exploration units of Daqing Petroleum Corporation. The details are shown in tables 4-1 and 4-2

Table 4-1 statistical table of exploration right certification by exploration stage (II) current situation of financial revenue from mineral resources exploration in Heilongjiang Province, If the application for mineral exploration right is made within the territory of China, a fee for the use of the mineral exploration right shall be paid; if the application for mineral exploration formed by state funded exploration is made, the price of the mineral exploration right shall be paid. In recent years, the number of exploration rights in the whole province and the payment of their royalties and prices are shown in table 4-3. It can be seen from the table that the number of paid exploration in the whole province was the largest in 2004, while the income of exploration right royalty and price reached the peak in 2005, that is 105 million yuan

Table 4-2 statistical table of mineral classification for exploration registration of exploration rights

Table 4-3 number of paid transfer of exploration rights and payment of exploration right use fee and price from 2002 to 2006 in Heilongjiang Province, Results of geological exploration from 2003 to 2007 solid mineral exploration has been steadily promoted in 2003, among which a certain number of polymetallic and precious metal anomaly areas, mineralization (mineralization) points and orebodies have been delineated by various geological exploration units with state subsidy, provincial subsidy and self investment funds, At the same time, some nonmetallic minerals with a certain scale have been found and a certain amount of resources have been obtained. There are many mining areas with breakthrough progress in exploration work in the province, including 4 small rock gold deposits, 2 small medium lead-zinc deposits and 2 medium large building materials non-metallic deposits. Dongan large-scale rock gold deposit has passed the national assessment, with proved reserves of 24.3 tons and average grade of 8.99 g / T

in 2004, a certain number of polymetallic and precious metal anomaly areas, mineralization (mineralization) points and ore bodies were delineated in various types of geological exploration funded by national subsidy, provincial subsidy and self investment, and a number of metallogenic areas and prospecting areas were predicted. At the same time, non-metallic minerals with a certain scale were found and a certain amount of resources were obtained. In 2004, there were many mining areas with breakthrough progress in the exploration work of the whole province, among which a more promising lead-zinc deposit was found in Bailing District of Acheng City; A medium to large scale molybdenum deposit has been found in Luming Ping'an District of Tieli city; Zhengguangyan gold deposit in Heihe City and Sanwanzi gold deposit in Heihe City are expected to be medium-sized or above

in 2005, the exploration results are relatively significant, with 620 million tons of new coal reserves and 10 tons of new resources reserves in the periphery of Xunke donganyan gold mine. Lead and zinc in the West Maya river area of Huzhong District, Daxing'an City, gold and silver in Shalan Town, Ning'an City, gold and silver in the second branch line of tahuan, Daxing'an City, Sangou Zhuweihe rock gold in Heihe City, gold and silver in the West Maya river area of Huzhong District, gold and silver in Shalan Town, Ningan City, gold and silver in the There are seven small to medium-sized mineral deposits and some important prospecting clues, including najinkouzi Yanjin in shangmachang township of Heihe City, lead-zinc tin in huangqigou area of Ning'an City, and Hanconggou iron in Shuangyashan City

In 2006, through the 1 ∶ 50000 regional geological and mineral survey, more than 40 ore spots (mineralization spots) were found, and 5 targets for further exploration were found; The central and provincial mineral resources compensation fees were used to arrange 57 geological exploration projects, with a project fund of 195720000 yuan. The predicted resources of Ningan yingchengziyan gold mine are 10 tons, Heihe zhengguangyan gold mine controls 20 tons of intrinsic economic resources, Shuangyashan Hanconggou iron mine infers 5 million tons of intrinsic economic resources, Daxing'anling area is expected to reach one medium-sized lead-zinc mine and one molybdenum mine, huma chair circle coal mine predicts 130 million tons of coal resources. The Bishui Pb Zn deposit in kalu mountain has been discovered in the Derbugan metallogenic belt, and the large-scale Luming Mo deposit in tielishi city has been discovered for the first time in the Xiaoxing'anling zhangguangcailing metallogenic belt in the middle of China. The amount of molybdenum that has been explored, controlled and inferred is more than 100000 tons. Meanwhile, the Huojihe Mo deposit of the same type has been discovered

in 2006, we actively implemented the "going out" strategy, relying on the provincial resource development and financing platform, established a reserve of overseas resource development loan projects, and operated 66 overseas projects. Longxing group has obtained the right to use the mineral resources of tashtek large lead-zinc Polymetallic Mine in the Republic of Tuva, Russia, and Harbin Longgang Real Estate Development Co., Ltd. has obtained the right to use the mineral resources of nerchugan coal mine in mogoya District, Chita Prefecture, Russia. The Provincial Geological Exploration Bureau has carried out preliminary investigation on Moneng iron mine in Santa Cruz Province, Bolivia. Heilongjiang Institute of Geological Sciences transferred 70% of the equity of lantarskaya mining company, recovered the initial investment and made a profit. The exploration of kunyan gold deposit has explored 35 tons of gold resources and predicted 90 tons of gold resources in the whole area. We visited the mining instry in South Australia, and initially reached the cooperation intention of copper mine. The mining group's placer gold mining work in the state of Magadan has been carried out normally. The Magadan rock gold exploration project has reached a transfer agreement with Hunan Dingxin company and invested in geological exploration. To investigate mineral resources in Bolivia has passed the preliminary project approval of Mutong iron mine. Heilongjiang Institute of hydrogeology and engineering geology has negotiated with the northern province of Australia, and reached a consensus on the cooperative exploration and development of mineral resources in the region. A gold mine and a tantalum iron mine have been selected as investment targets in Zimbabwe. The Provincial Regional Geological Survey Institute has reached an agreement with the Russian coastal frontier to develop the Hongshan lead-zinc mine

In 2006, Qiqihar General Institute of mineral exploration and Australia renegotiated on the Zhengguang rock gold cooperation project, and most of the compensation funds were in place; The first Academy of geological exploration cooperated with Dalian new development group, which has invested 4 million yuan in risk exploration; The Fourth Geological Exploration Institute successfully operated geothermal projects; Luming molybdenum mine, Hongqishan iron Polymetallic Mine and daxinxicha silica mine have successfully cooperated with each other. The sixth Institute of geological exploration has extended the mining rights of cuihongshan iron Polymetallic Mine, and the mining rights cooperation of Huojihe Polymetallic Mine is also fully promoted. The research institute cooperated with Australia to set up Longbang mining and introced Australian capital of 1 million Australian dollars. The mining group renamed the exploration license of Duobaoshan copper deposit to ensure the overall development of Duobaoshan ore field. The Sanwanzi gold mine has been developed by Heilongjiang Provincial Geological Prospecting Bureau and Fujian Tianbao Group, and has been put into operation

In 2007, the China Geological Survey and the Provincial Department of land and resources signed the agreement on cooperation in mineral prospect survey in Duobaoshan area of Heilongjiang Province on November 2, with an investment of 40 million yuan to carry out comprehensive method and technology test and demonstration of mineral prospect survey in this area in three years. We will start the investigation of coal resources in the whole province. After many times of communication and coordination, the provincial finance plans to invest 200 million yuan to carry out the investigation of coal resources in the whole province in five years from 2007. In 2007, three blocks were investigated, covering an area of 27800 square kilometers, with an estimated capital of 76 million yuan. Carry out the pilot work of urban geological survey. The Provincial Department of land and resources signed a cooperation agreement with Harbin municipal government, with a joint investment of 50 million yuan, to carry out the pilot work of urban geological survey in Harbin in three years, so as to provide the basis for the prevention and control of urban geological disasters, geological environment assessment, ecological environment improvement and urban construction and development. One large-scale mineral deposit of Fuxing coal mine in Suibin County, two medium-sized mineral deposits such as Yanjin in shangmachang township of Heihe City and Bishui lead-zinc mine in Daxinganling area, yanweishan Copper Polymetallic Mine in Huzhong District, Luannigou gold silver mine in Huanan County, ervayan gold mine in Huanan County, peripheral gold (silver) mine in Yingchengzi of Ning'an City, etc There are 5 small-scale mineral deposits in daziyangshan Hongguang area of Songling District, Daxinganling. New resource reserves: 402 million tons of coal; Metal quantity: 6.4 tons of gold, 4300 tons of molybdenum and 8600 tons of tungsten; 30000 tons of lead and zinc; Ore quantity: 3.4 million tons of iron. It has effectively improved the ability of mineral resources to guarantee the sustainable development of economy and society. With an investment of 10 million yuan, three large-scale deposits, three medium-sized deposits, three ore occurrences and a number of important prospecting clues have been discovered in two years

In 2007, the provincial Kunyuan company and imperial mining company (laos) carried out the general survey of the mengbaben gold project on the Mekong River

In January 2008, China Geological Survey Bureau of the Ministry of land and resources and Heilongjiang provincial government signed the agreement on public geological survey and strategic mineral exploration of Heilongjiang Province in Harbin. The signing of the agreement is a new exploration of the central and local cooperation in public geological survey, It is also an important measure to improve the level of basic geological work and research, promote geological and mineral exploration, and achieve a major breakthrough in geological prospecting. According to the agreement, it is determined to carry out public geological survey and uniformly deploy geological prospecting work in key metallogenic zones; To carry out regional geological survey, regional geochemical exploration, exploration technology and method test, mineral prospect survey and major geological problems research; Carry out the investigation and evaluation of coal resources and unconventional energy; Carry out urban geology, hydrogeology and environmental geology survey; Research on the protection and disposal of public geological survey results will be carried out. At present, 1.36 billion yuan of various cooperation projects has been initially set. The cooperation period is from 2008 to 2015

(1) newly discovered ore procing areas and newly identified reserves of mineral resources

in 2008, four phased exploration coal mines were completed, including one large (exploration), one medium (general survey) and two small (detailed investigation and Exploration); In this year, 7 coal mines (1 large, 1 medium and 5 small) and 2 molybdenum mines (1 medium and 1 small) were discovered; In this year, 4 coal mines (2 large and 2 medium) were upgraded. The newly identified (333) grade or above mineral resource reserves are 738253 thousand tons of coal, of which 256633 thousand tons have been reviewed and recorded, 26550 thousand tons have been reviewed and geological exploration report has not been reviewed and 455070 thousand tons (associated oil shale 17400 thousand tons); The amount of molybdenum is 18008 tons (without review of geological survey report); Gold metal 7107kg (without review of geological survey report)

(2) great achievements have been made in the exploration of Replacement Resources in crisis mines since 2006, eight large and medium-sized state-owned mines in the province have carried out mine replacement resources exploration projects. In 2008, there were 6 exploration projects of Replacement Resources in crisis mines, of which 3 projects achieved remarkable geological prospecting results. Hegang coal mine in Heilongjiang Province is a large state-owned coal mine. Before the implementation of the project, it has 1530 million tons of (333) grade and above resources. According to the preliminary estimation, there are (333) + (334) new additions? Coal resources 319.49 million tons (without geological survey report review)

9. The 80 / 20 rule is the principle of arranging priorities according to the importance of things. It is based on the principle of "important minority and trivial majority". This principle was put forward by the Italian economist and sociologist Victor Pareto in the late 19th century and early 20th century. Its main idea is: in any specific group, the important factors usually account for only a few, while the unimportant factors account for the majority, so as long as we can control the important few factors, we can control the overall situation. Pareto once proposed that 80% of the wealth in Italy is owned by 20% of the people, and this economic trend is universal. Later, people found that there are many things in the development of society, are moving towards this track. At present, many experts in the world are using this principle to study and explain related topics. For example, after years of evolution, this principle has become the well-known "80 / 20 principle" in today's management circles, that is, 80% of the value comes from 20% of the factor, and the remaining 20% comes from 80% of the factor. Pareto's law, also known as 80 / 20 law, was discovered by Italian economist and sociologist Pareto. At first, it was limited to the field of economics. Later, it was also extended to all fields of social life, and was deeply recognized by people. Pareto rule means that in any large system, about 80% of the results are generated by about 20% of the variables in the system. For example, in an enterprise, 80% of the profits usually come from 20% of the projects or important customers; Economists believe that 20% of the people hold 80% of the wealth; Psychologists believe that 20% of people have 80% of their wisdom. When it comes to time management, it means that about 20% of the important projects can bring 80% of the whole work results, and in many cases, the first 20% of the work time will bring 80% of all benefits. The Enlightenment of Pareto's law to us is: great wisdom has no worries, great cleverness has no actions. You should avoid spending time on most trivial problems in your work, because even if you spend 80% of your time, you can only achieve 20% of the results, and it is the most time-consuming to finish unimportant work excellently. You should spend your time on a few important issues, because if you master these few important issues, you can achieve 80% results in only 20% of your time. In our work, we should learn to "catch no small fish and whale". If you catch 100 small fish, all you have is a bucket full of fish, but if you catch a whale, you are not in vain. The 80 / 20 rule has also been extended to all parts of social life, and is deeply recognized by people. For example, in an enterprise, it is generally believed that 80% of its profits come from 20% of its projects or important customers; Economists believe that 20% of the people hold 80% of the wealth; Psychologists believe that 20% of people have 80% of their wisdom; By extension, we can think that in any large system, 80% of the results are proced by about 20% of the variables in the system. An important enlightenment of the "80 / 20" principle to everyone is to avoid spending time on trivial majority problems, because even if you spend 80% of your time, you can only achieve 20% results: you should spend time on important minority problems, because if you master these important minority problems, you can achieve 80% results in only 20% of your time. 1. Learning and training must spend 80% of the time and energy to participate in learning and training. When you really go to marketing, you can use 20% of the time and energy to learn new things. 2. 80% of sales time is work, 20% is rest. 3. The understanding of target customers is 80%. It only takes 20% effort to achieve 80% success. If you know nothing about the target, even if you try 80% of your best, you have only 20% chance of success.  4. Only 20% of the customers who can really accept your promotion in the marketing market, but these people will affect the other 80% of the customers. You have to spend 80% of your energy on finding these 20% of your customers. 80% of the performance comes from 20% of the regular customers. 5. Listening and speaking use 80% of your ears to listen. If you nag 80% of the time, your chances of success will drop to 20%. Use only 20% of your mouth to persuade customers. 6. First impression 80% of the first impression comes from appearance. In front of customers must spend 80% of the effort to smile, it is better than the image established with 80% of the words, so it is necessary to spend 20% of the time to decorate before going out. If the customer thinks you are serious and inaccessible, your chances of success will be reced to 20%. 80% of emotion and introction come from the success of communication and emotion building. If you use 80% of your energy to make yourself close to the customer and try to be friendly to him, you only need to spend 20% of your time to introce the proct, and 80% of your hope for success comes from the success of demonstration and introction of the proct. If you only use 20% of your efforts to make friends with customers, even if you use 80% of your efforts to introce procts, it will be in vain. 7. Success and failure in the practice of sales promotion, 80% of the people will fail, and 80% of the people will retreat because of the difficulties. 80% of success is e to personal qualities and skills. But 80% of the salesmen are not trying to improve themselves, but complaining and waiting. Only 20% of the reasons for success are e to the environment and luck. Only 20% of the people will succeed, and these 20% will bring 80% benefits to their enterprises. 8. Bargaining 80% of the customers will say that the price of the procts you sell is high. But you don't have to spend 80% of your time to bargain, you must spend 80% of your strength to prove how much benefit it can bring to the customers, which is very important. You only need to use 20% of your strength to prove why the price of your things is high enough. The salesperson can choose: or look forward to a little luck, look forward to your Savior and gamble all his life; Or through self-improvement to increase their own opportunities. Salesmen can be static and then fail; You can also enre the pain of growing up and succeed. In this regard, a successful salesman should make a wise choice. To promote sales, we should start with self promotion. If you can take the above requirements as rules and consciously implement them, the hope of success will be above 80% and the possibility of failure will be below 20%. Pareto principle means that the world is full of imbalance, such as 20% of the population has 80% of the wealth, 20% of the employees create 80% of the value, 80% of the income comes from 20% of the goods, 80% of the profits come from 20% of the customers, and so on. According to this rule, resources will always adjust themselves to minimize the workload. The imbalance relationship can also be called the two eight rule. If we do a good job in solving 20% of the major problems, the other 80% will be solved. Therefore, in the work to learn to grasp the key minority, to use 20% of the energy to pay 80% of the return. Therefore, this kind of rule is also called labor saving rule.  1. When the enterprise management uses the rule of 28 to manage the enterprise, it is necessary to make clear which aspects of the company are profitable and which aspects are losing money. Sort out the profitable part, so as to formulate a set of strategies concive to the growth of the company. Secondly, it is necessary to find out which departments have mediocre performance, which departments have created higher profits, and which departments have brought serious deficits. Through comparative analysis, we will find out the main factors. There are only a few profitable projects, so we should pay more attention to them. 2. The 28 principles of human resource management are also applicable to human resource management. The proction efficiency and future development of an organization often depends on a few key people, who can help the enterprise obtain most of the profits. Most people contribute to the development of the enterprise. They seem very busy, but they don't create much value for the development of the company. To find the key minority, we should establish an effective income distribution mechanism to prevent the loss of key personnel. What are 20% of the backbone, 20% of the key procts, 20% of the key customers, 20% of the key information and 20% of the key projects? Then focus on the 20% and take effective follow-up measures. 3. Dealing with interpersonal relationship among the people we know, most of them are general friends. A small part of interpersonal relationship is equal to the majority of emotional value. A small number of deep interpersonal relationship is better than extensive and superficial communication. Therefore, 80% of the time should be spent on the interpersonal relationship of 20% of the important people. 4. There may be a lot of expertise in life planning, but few of them really play a role. Therefore, we should be good at mastering our own advantages and looking for those things that we like very much, are good at, and are not very competitive to do. We will certainly gain. Only by finding the most important things in life can we have a successful life. In the arrangement of their own time, not to do something can be done. We should concentrate our time and energy on key people, key links, key posts and key projects.
