30 people for mining promotion
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
Safety has always been the most important issue in mining instry, especially for underground mining. Although modern mining instry is safer than decades ago, accidents often occur
mine ventilation is the key to ensure the safety of miners. Poor ventilation will lead to silicosis. Especially in coal mines, it will cause gas (methane) accumulation and explosion. The ventilation system is completed by the powerful exhaust fan, which makes the mine reach the negative pressure, and the fresh air will be imported into the mine by other pipes, so as to achieve good air circulation. The mineral resources law, revised in 1996, has made important amendments and improvements to China's legal system of mining rights, established a system of paid acquisition and legal transfer of exploration and mining rights, which is suitable for the socialist market economic system and in line with international practices, and clarified the legal status of foreign investment in exploration and mining of mineral resources. In February 1998, the State Council promulgated three administrative regulations, namely, the administrative measures for the registration of mineral resources exploration blocks, the administrative measures for the registration of mineral resources exploitation, and the administrative measures for the transfer of exploration right and mining right, which further specified the system of exploration right and mining right, and determined that under normal circumstances, foreign investors or Sino foreign joint ventures, mining right transfer, etc A contractual joint venture may directly apply for the right to explore and develop mineral resources. It shows that in the field of mineral resources exploration, development and opening to the outside world, foreign-invested enterprises and domestic enterprises enjoy equal national treatment
in 2000, the Ministry of land and resources issued the notice on issues related to the application for exploration rights by foreign-related unincorporated enterprises, which clearly stipulates that all foreign-related joint ventures, cooperative companies, offices and representative offices that are officially registered in China's instrial and commercial administration authorities and obtain business licenses for unincorporated enterprises can refer to the applicants with legal personality, The application for mineral exploration right and geological exploration unit qualification in accordance with the law shall go through the examination and approval proceres at the Ministry of land and resources, and be included in the unified management of geological exploration unit qualification nationwide. Subsequently, the Ministry of land and resources and the Ministry of Finance issued the notice on printing and distributing the methods for recing and exempting the use fees of exploration and mining rights, and formulated certain preferential policies< In December 1999, the Ministry of Finance promulgated the regulations on accounting treatment of exploration right and mining right of enterprises and the regulations on accounting treatment of exploration right and mining right of geological exploration units to clarify the entry cost of exploration expenses< On September 28, 2000, the Ministry of land and resources, the State Planning Commission, the State Economic and Trade Commission, the Ministry of finance, the Ministry of foreign trade and economic cooperation, and the State Administration for Instry and Commerce jointly formulated and promulgated several opinions on Further Encouraging Foreign Investment in exploration and exploitation of non oil and gas mineral resources. Foreign companies and their offices and representative offices established in China are allowed to conct risk exploration of non oil and gas mineral resources in the form of sole proprietorship or cooperation with China; The preferential policies for foreign investors to explore and exploit non oil and gas mineral resources are clearly stipulated; Special encouragement will be given to foreign investors in the exploration and exploitation of non oil and gas mineral resources in the western region
the main problems existing in China's current non-ferrous mining policy are as follows:
first, insufficient support and narrow financing channels
after the "transfer of funds to loans", nonferrous mining enterprises are short of funds, the burden of interest is heavier, and the financing channels are narrow. On the one hand, commercial banks and other financial institutions are reluctant to invest in mining instry e to the risk and low profit of the mine; On the other hand, e to the influence of investment environment and mining policy, the domestic and foreign financing channels of China's nonferrous mining instry are not smooth. As a result of these factors, some mines with better resource conditions can not be developed in time e to financial problems
secondly, there are many kinds of taxes and heavy taxes
VAT. After the tax system reform in 1994, although the value-added tax of nonferrous mining enterprises was adjusted to 13% in May of that year, compared with the previous tax rate of the same caliber, the mine tax still increased significantly
resource tax and resource compensation. Since the introction of resource tax on January 1, 1994, the proction cost of mining enterprises has increased significantly. In addition, the resource compensation fee will be levied from April 1, 1994. It is unreasonable to levy both resource tax and resource compensation fee. Moreover, the resource compensation fee of mining and metallurgy enterprises is much higher than that of single mining enterprises, which makes the tax of mining and metallurgy enterprises "worse"
thirdly, the implementation of overseas development policies is not in place
although the State encourages and supports the development of domestic shortage of copper, nickel, gold, silver and other mineral resources abroad, the actual implementation process is not satisfactory. For example, chambisi copper mine in Zambia is a cooperative project determined by Premier Zhu Rongji when he visited Zambia in 1995, and it is also the first copper mine independently developed by China abroad. In July 1998, China Construction Group signed agreements with Zambia on the purchase of 85% equity of Chambishi Copper Mine and mine development. Due to the implementation of funds and other issues, the current development and proction of the copper mine has encountered difficulties. In recent years, underground mining technology has developed rapidly at home and abroad, and many new mining technologies, new processes, new materials and new equipment have been applied in underground mines. Some domestic mines and a number of advanced mining technology and equipment have stepped into the ranks of the world's advanced level. The development of mining technology and equipment in underground metal mines at home and abroad is mainly reflected in the great changes in the proportion of various mining methods, mining technology and technical equipment, which are developed along the direction of high efficiency, high recovery rate and mechanization. The stope proction capacity and labor proctivity have been greatly improved, and the loss and dilution index have been greatly reced. At present, the main mining methods are filling mining method, open stoping mining method and caving mining method. According to the statistics of 18 key iron mines, caving method accounts for 94.1% and open stoping method accounts for 5.9%. In gold mines, filling method accounts for 31%, open stoping method 65% and others 4%. In nonferrous metal mines, open stoping accounted for 46.1%, filling 19.6% and caving 34.3%. From the above statistical data, the underground mining of iron ore is still dominated by caving mining method, while the underground mining of non-ferrous and gold mines is still dominated by open stoping and filling mining method. In the past ten years, the filling mining method and filling technology of underground metal mines have developed rapidly, and the caving mining method and open stope mining method are constantly improved and innovated. Therefore, it promotes the rapid development of underground mining technology of metal mines in China, and makes the technology of some mines reach the international advanced level
if it is more than 300 or equal to 300, only 500 points will be added...
after a lot of data analysis and practical experience, as far as the current situation is concerned, leasing mining bitcoin is the most effective way to make money
why rent mining machines
this is because the efficiency of our personal money digging is too low. Other people are walking like a snail, so we need to expand our computing power by leasing mining machine contracts, so as to achieve the goal of easier money digging<
firstly, select the platform to register
bitcoin as the virtual digital currency, which needs to be registered and registered with the help of the platform supporting bitcoin transaction, in order to generate income from mining. It should be noted that it is very important to choose the right platform, which is directly related to the smooth progress of bitcoin trading and transfer. The survey found that the comprehensive strength of nashayun mine is relatively strong. For the convenience of operation, the mobile phone can be used directly to the mine
mining equipment must be excellent
if you want to dig bitcoin, you must have professional equipment and excellent ability. As I have just said, the ability of indivial mining is very limited. Leasing mining machines is more profitable than the traditional model. At the same time, it requires mining machines to give full play to computers and other equipment. The mining machinery in nashayun mine is relatively comprehensive, with different cycle mining machinery modes to choose from. One click payment, direct start, safe, reliable and guaranteed
why not keep mining profits for yourself
leasing mining machinery requires cost investment. We need to rent mining machinery at a more favorable price in order to have a richer working capital. If you don't sell the cloud computing power contract, you will have to use your own capital to buy more mining machines. It can be seen that only leasing enough mining machines can ensure the continuous output of bitcoin
that Sha Yun mine has long term welfare activities, for example, the cash recharge of 5000 yuan or more can be repaid by 2% from the bank account. The bank's payment can be used: online bank transfer, mobile phone bank transfer, WeChat transfer bank card, Alipay transfer bank card or ATM cash deposit company bank account. The amount of cash back can be withdrawn directly)
in addition, newly registered members will send 26 yuan in red envelope cash and sign in daily to give away mining machines; The more days of continuous check-in, the more days of free miner use
bitcoin is becoming more and more popular as a virtual encrypted digital currency. At present, there are many bitcoin mining software launched on major websites. I hope you will be able to distinguish the good from the bad, and choose nashayunkuang, which is definitely a platform worth choosing. I believe that in the future, it will be further developed to become the world's general currency, and you will all be able to take a share of bitcoin.
in fact, there are many places
there are 4-5 mines, which are enough for you to keep digging
