warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

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

25000 mining troops in Sichuan: a flood cost hundreds of millions, most afraid of power failure and loneliness
these computing power are scattered along the Da River, a tributary of the Minjiang River. They inlge in the night of Dalate Banner in Ordos, and sleep soundly in a small city in Yili Kazakh Autonomous Prefecture of Xinjiang
today, bitcoin's total network computing power has reached about 30 billion hash collisions per second, equivalent to about 600 tianhe-2 supercomputers, and it is still growing at a high speed. " Wu Jihan, the founder of bitcontinent, wrote in the beauty of computing power
he preached a set of infinitely beautiful "computational aesthetics", but behind the aesthetics is the cruel computational world and interests. Mining is moving towards instrialization step by step and becoming a game of capital
at this time, decentralized mining machines and pools began to appear. They called themselves revolutionaries and wanted to change the extremely monopolized bitcoin world
"cloud computing power mining" is one of them
their way of playing is to establish a number of distributed mines and provide computing power leasing services with tens of thousands of real mining machines
"the current computing power is too concentrated, and some decentralized play methods are difficult to change the current pattern and ecology." Li Ke said
but the essence of blockchain is decentralization. The miners still have the belief that eventually the mining instry will be broken by the decentralized mining pool
this may be the only belief that keeps them going
how long will it take
"5-10 years, slowly nibbling at the giant's territory." Li Ke said
but will giants wait for the revolution? Will they fight back
the battle of computing power and the spark of revolution have just been ignited

AC can be easily increased or decreased by transformer, so as to realize long-distance transmission, and the rated voltage of electrical equipment with different power can be adjusted. This is an advantage of AC. power line can be connected with electrical equipment to realize power transmission. But wire resistance, current through heating, this heat is useless, nothing is wasted. In the transmission of electric energy, how to rece the energy loss is studied, so as to effectively use the power resistance
line, now it's me, so the power line loss is p = the total length of I2R line. Design L, the cross-sectional area s of the conctor, knowing that the starting resistance R = P L / s
the actual transmission power method, considering various factors, selects cross transmission voltage and conctor cross-sectional area according to different situations. Large generators proce voltages of 1500 V, 13800 V, 15750 V and 18000 V, which cannot be transmitted directly. In the power station, step-up transformer is needed to boost the power supply, and then it is transmitted to the remote. China's long-distance transmission uses voltage of 110000V, 220000v and 33000v, and voltage supply of 500000 V has been adopted in some areas. The highest test transmission voltage in the world is now 1.15 million volts. Voltage
long distance transmission is very high, and the direct application of electrical equipment, so the power area, as you said, according to different users, establish county-level substation, such as 220kV, 110KV, 35kV, 10kV substation, rece the voltage step by step, and the voltage drops to 10000 V, and send it to the power station that needs high voltage, and the voltage drops to low voltage of 220 / 380 V, for general users, such as families Schools, shops, organs, enterprises and institutions
with the construction and development of urban and rural areas, the distribution network for China's power consumption is increasing rapidly, and the task of 10kV power supply is becoming more and more important. In order to ensure 10kV power supply and distribution network with increased safety, economic and reliable operation, China has launched a matching power planning and practical design experience, For example, the design code of power supply system and technical specification for design of 10kV substation and 66kV and below overhead power lines, design specification for overhead distribution lines, design specification for insulation on overhead distribution lines, design specification for power engineering, 3 ~ 110kV High voltage cables, are included in the design code for rural power network planning and design as urban power grid planning and design guide and urban planning standard Code for design of power distribution devices "code for design of relay protection and automatic devices", "code for design of electrical measurement and energy metering devices" and "Atlas 10kV and below power distribution line project" Atlas 10kV and below power distribution equipment project "of" 10kV and below atlas ". Friends who are interested in consulting county power professionals can also borrow books from them.
photovoltaic power generation is essentially the same as hydropower generation
as long as the electricity is cheap
generally speaking, if the electricity charge is more than 30 cents, you can hardly earn money from mining.
for this virtual thing, the power consumption is terrible.
