1. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
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

The miner is better
-
the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge
-
mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />

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
4.
At present, the mining machinery is in a state of two-level differentiation, such as the better ones: the interstellar Aoyun, ants, and Xindong are all OK, and the interstellar Aoyun focuses on IPFs. In addition, some other mining machine chip enterprises are also faced with challenges. In addition to the main mining machine chips, they have begun to layout and promote the artificial intelligence business to expand new possibilities
5. Bitcoin, in short, is an internationally recognized virtual currency. In some foreign countries, bitcoin can be used to trade; In China, it was also announced a while ago that bitcoin withdrawal might be tried out
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it
mining is definitely the first professional mining machine. Many new children's shoes will choose to mine with graphics card. However, mining with graphics card is just like doing a professional job with "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

7. Nakamoto once said that the number of bitcoins is fixed at 21 million. Since the bitcoin was g out, the price has been high. However, with more and more miners, we all see the fat of blockchain mining. Mining is naturally more and more difficult, so it is very important to choose a good miner. At present, the mainstream miner is ASIC miner, graphics card miner, GPU miner, storage miner. Specifically, we need to find a professional mining platform to ask, such as jinhoe mining, professional mining platform, each miner model should have it, you can try to ask.
