260t calculation of daily electricity charge
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and 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
the popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
the price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, high configuration bitcoin & quot; Mining machine & quot; From 10000 yuan to 300000 yuan, but the performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013.
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad 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 some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data
mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
now the comprehensive water price of Beijing residents is 4.0 yuan per cubic meter. Among them, 1.70 yuan per cubic meter for residents, 1.26 yuan for water resources, and 0.90 yuan per cubic meter for sewage treatment. The water resource fee for self provided wells is 2.30 yuan per cubic meter according to the provisions of FGR [2009] No. 2400 document
2. The price of water for non residents in Beijing
is 5.80 yuan per cubic meter for administrative institutions and 6.21 yuan per cubic meter for Instry and commerce. Hotels and some catering chain stores use water for Instry and Commerce in the same year. According to the above standards, the price for car washing and purified water instry is 61.68 yuan per cubic meter, and that for bath instry is 81.68 yuan per cubic meter
in addition, Beijing plans to implement a stepped water price. The so-called stepped water price is to divide the water standard into several stages, and each stage implements different water price standards. The first level water consumption base is mainly based on the principle of ensuring the basic domestic water consumption of residents. The second level water base is based on the principle of improving and improving the quality of life of residents. The third level is set according to the principle that the market price meets the special needs
following the rection of general instrial and commercial sales price on May 1, the price will be lowered again in Beijing on July 1. The Beijing Municipal Development and Reform Commission yesterday (May 31) issued a notice that in order to further rece the power consumption burden of instry and commerce, according to the unified deployment of the national electricity price adjustment, from July 1, 2019, Beijing will further rece the electricity price of general instrial and commercial users (except the low period) by 2.63 cents / kWh, and simultaneously rece the transmission and distribution price of general instrial and commercial users and other users by 2.02 cents / kWh. It is estimated that the annual tariff burden of general instrial and commercial users will be reced by another 1.016 billion yuan on the basis of the rection of 469 million yuan on May 1
in order to actively optimize the business environment, Beijing has reced the electricity price of general instry and Commerce for six times since 2018, with a cumulative average rection of 9.50 cents / kWh, recing the annual electricity burden of general instry and Commerce users by 4.595 billion yuan.
