Daily maintenance of mining machine
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million
mining machine is a tool for procing and mining bitcoin
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

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

Ball mill is the key equipment to crush the material after it is crushed. This type of mill is filled with a certain number of steel balls as grinding medium in its cylinder. It is widely used in cement, silicate procts, new building materials, refractories, chemical fertilizer, black and non-ferrous metal mineral processing, glass ceramics and other proction instries, dry or wet grinding of various ores and other grindable materials. Ball mill is suitable for grinding all kinds of ores and other materials. It is widely used in mineral processing, building materials and chemical instry. It can be divided into dry grinding and wet grinding. According to the different ways of ore discharge, it can be divided into grid type and overflow type. Ball mill is the key equipment to crush the material after it is crushed. Ball mill is one of the high fine grinding machines widely used in instrial proction. There are many kinds of ball mills, such as tubular ball mill, rod ball mill, cement ball mill, ultra-fine laminated mill, hand ball mill, horizontal ball mill, ball mill bearing bush, energy-saving ball mill, overflow ball mill, ceramic ball mill, lattice ball mill. Ball mill is suitable for grinding all kinds of ores and other materials. It is widely used in mineral processing, building materials and chemical instry. It can be divided into dry grinding and wet grinding. According to the different ways of ore discharge, it can be divided into grid type and overflow type. According to the shape of the cylinder, it can be divided into short cylinder ball mill, long cylinder ball mill, tube mill and cone mill. The ball mill is composed of horizontal cylinder, feeding and discharging hollow shaft, grinding head and other parts. The cylinder is a long cylinder, which is equipped with grinding body. The cylinder is made of steel plate, which is fixed with the cylinder by steel lining plate. The grinding body is generally a steel ball, which is loaded into the cylinder according to different diameters and a certain proportion. The grinding body can also be used as a steel section. The grinding material is selected according to the particle size. The material is loaded into the cylinder by the hollow shaft at the feed end of the ball mill. When the cylinder of the ball mill rotates, the grinding body is attached to the lining plate of the cylinder e to inertia, centrifugal force and friction, and is taken away by the cylinder. When it is brought to a certain height, it is thrown down e to its own gravity, The falling grinding body smashes the material in the cylinder like a projectile
