Features of mining machine
in fact, no matter what the mining friends ask, what attracts them most is the super cost performance of mining machinery. Hummingbird H1 is the first IPFs family miner of starbit, which is equipped with IPFs OS operating system (based on Linux) and supports 20tb hard disk expansion. In terms of hardware, considering the high noise, high power consumption and other disadvantages of traditional mining machine, hummingbird H1 has carried out a comprehensive optimization for the home scene, while ensuring the hardware performance (supporting 20tb expansion), controlling the noise at & lt; 30 dB, close to silence; At the same time, the power consumption of the mining machine has been effectively controlled. The annual electricity charge is about 150 yuan, which greatly reces the investment cost.
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
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
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
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

Horizontal centrifugal mill has high grinding efficiency when it is used for fine grinding and ultra-fine grinding. According to the test of the former Soviet Union, the centrifugal mill with a volume of 2 m3 can replace the ball mill with a volume of 20 m3. Using a centrifugal mill instead of a ball mill can save 40000 rubles only in terms of recing metal consumption. In recent years, the Soviet Union adopted Φ eight hundred × 1000 mm centrifugal mill instead of concentrator Φ two thousand and seven hundred × 3600 mm ball mill is used for regrinding middlings and concentrates. Instrial tests show that better economic benefits can be obtained. Developed by Lurgi and South Africa Φ one × The 1.2m, 1400kW centrifugal mill was put into operation in South Africa gold mine in 1979. Centrifugal mill can be used in wet open circuit process and closed circuit process with hydrocyclone
The price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, the high configuration bitcoin "mining machine" increased from 10000 yuan to 300000 yuan, but its 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. Mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, the computing power after "grouping" can surpass the single graphics card of most users. And this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Taking into account the hardware price and other costs, there is a considerable expenditure in mining< br />
