Us bitcoin mining machine
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
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. 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 money circulation. 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
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.
Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension
after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card
CPU is not very important. But not lower than i5< br />

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.
bitcoin mining machine scam is to make money by leasing or selling mining machines the so-called "mining machine" refers to the computer that installs and runs specific software and algorithms. As we all know, bitcoin can only be obtained through long-term running algorithm of computer, and the total amount is limited. Therefore, some manufacturers have launched specially designed and optimized computer procts, known as "mining machine" in January 2018, a mining computer named "Kodak kashminer" appeared at the international consumer electronics exhibition in Las Vegas, which aroused people's attention. But now critics point out that the mining machine plan is actually a fraud, and the publicity for profit is also false precautions: 1. The general computer configuration of bitcoin household can not meet the requirements of bitcoin miner, so it is difficult to earn the electricity cost of a day 2. If you have to use bitcoin mining machine to dig coins, it is suggested to choose a reliable and legal platform to go more steadily. In the legal platform mining, the daily income can be seen, and a certain amount can be withdrawn
