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

Although the price of bitcoin has suffered a sharp drop before the Spring Festival, there are still some people who are obsessed with "mining". Therefore, mining equipment has become a hot spot, and some people have made a fortune

analysts from Bernstein, a well-known US investment bank, estimate that in 2017, the operating profit of a Chinese start-up company named bitmain in China may reach US $3 billion (about RMB 19 billion) to US $4 billion (about RMB 25.3 billion), which is equivalent to that of chip giant NVIDIA

However, it took bitmainland only four years to achieve such a high profit in one year, while NVIDIA spent 24 years

bitmainland's operating profit may exceed US $3 billion

according to the conservative expectations of 75% gross profit margin and 65% operating profit margin, bitmainland's operating profit in 2017 is US $3 billion to US $4 billion, while NVIDIA's operating profit in the same period is US $3 billion. In a report released on Wednesday, Bernstein analysts said it took bitmainland only four years to achieve this goal, while NVIDIA took 24 years

According to Bernstein's report, each of the antminer bitcoin mining devices currently sold by bitmainland is worth hundreds to thousands of dollars. In addition, the company operates "mining pools" that allow participants to collaborate on bitcoin mining to rece costs. Bernstein estimates that bitmainland has 70% to 80% market share in bitcoin miners and ASICs

according to the daily economic news, the ethash algorithm currently used by Ethernet is based on the demand of graphics chip, which is suitable for PC mining, and the mining machine is not good at it. The market expects that bitmainland will soon launch a new mining machine with low energy consumption and high efficiency. A professional mining machine can be equivalent to several 8-graphics card mining machines. After the official launch, it is bound to impact the original PC mining market with graphics chips. At that time, because of "mining" and soaring chip prices are also expected to return to rationality

Mitch Steves, an analyst at RBC Capital, believes that the price of Ethernet currency has skyrocketed from $10 in early 2017 to $1000 now, and the possibility of exclusive mining chips is much higher than a year ago. Steves also pointed out that if bitmainland really sells chips dedicated to Ethernet coins, the mining efficiency will be far better than that of graphics chips, and at that time, it will take away the business of NVIDIA and AMD

according to the daily economic news, NVIDIA's financial report for the fourth quarter of 2017 released in early February found that the company's data center, including the sales of graphics processing units (GPU and graphics card), had an operating revenue of US $606 million in the fourth quarter, making it the second largest revenue source of NVIDIA. The chief financial officer of NVIDIA also mentioned that in terms of the overall demand for NVIDIA procts, the contribution of digital money market is difficult to quantify, but I believe the percentage contribution in the fourth quarter is higher than that in the previous quarter

4. The ant S9 proced by bitmainland is the most mainstream mining machine on the market, which is famous for its low power consumption and high output. Ant mining machine S9 adopts TSMC's 16 nanometer FinFET process. TSMC comes from the agent factory of iPhone chip, and ant also applies the full custom design scheme on S9. So, this makes S9 have super computing power upgrade, let mining efficiency is higher. S9 adopts the latest generation chip bm1387 (189 chips in total), and the computing power of a single chip reaches 74gh / S. in terms of power consumption, S9 maintains at 0.08w/gh/s. (the power consumption is 0.08w/gh/s at 0.4V core voltage, and the power consumption per T computing power wall is only 100W, which is only 2.4 kwh per day. Rated calculation force: 13.5th/s ± 5%

Xuebao miner A1, miner chip is the core of miner. It is said that bitmine is the source of the whole bitcoin miner instry. Bitmine has its own powerful chip technology as early as the end of 2013. Of course, it also benefits from the joint cooperation and efforts of bitmine and other companies, and Xuebao miner is their own proct. A1 is the world's first customized mining machine, equipped with ASIC chip (bf16btc), the number of chips is as high as 576pcs, the computing power of a single chip is 84.1gh/s, and the overall computing power is as high as 49th / s ± 5%

Z4 adopts Intel al core [email protected] Cup, mining power is 265mh / S (ETH), equipped with independent graphics card 570x8, has 9 fans, and the radiator adopts Intel original radiator, power supply: station flag 2000W power supply, voltage: 12.4-12.6v.

Hello, there are many Shenma mining machines and ant mining machines in bitcoin mining machine market at present.

if you buy a mining machine, you should first consider the computing power and cost of the mining machine. If the computing power is large, the yield of coins will be higher, and the cost of low computing power will be lower.

it is suggested that you visit bitfan website to check the mining machine market, The figure below shows the market comparison of bitcoin miner on June 11

if you have any other questions, please ask me, hope to help you, thank you

6. Asicme, as well as roasted cat, now it seems that asicme has become the largest miner in China. I forget which news I read. The main procts of roasted cat are USB miner and blade miner, but the mining capacity is a little low and the price is relatively high. Comparatively speaking, asicme is more cost-effective. Hand fight, please accept.

7. Butterfly laboratory in the United States is from the United States. He prefers to evade tickets. It seems that he has been prosecuted recently. As we all know, the overall performance of the garden miner is not good, and the energy consumption of the ant miner is relatively small, but the chip is made by 55nm process technology. According to the development of current technology, it will be eliminated soon. Cat roaster used to be brilliant for a time, but with the technological progress of other mining machine manufacturers, it graally went down. In contrast, Avalon has been at the forefront of innovation. Avalon delivered the world's first ASIC miner. Avalon1 once made a noise from 8000 to 300000. Avalon's second-generation chips contributed about one third of the computing power of the whole network in January. At present, Avalon has delivered the first batch of orders for the third generation chips with 40nm process technology.

8. Now I recommend my English tutor to you. I think this software is the best at present,

has strong speech recognition ability. You can listen to a dialogue first, and then choose roles and calculations to have a dialogue. If your pronunciation is not on time, the computer will automatically repeat accurate pronunciation until your comprehensive score of pronunciation (divided into several assessment items) meets the basic score of 80, At first, there are a few free courses. As you contact more and more, naturally, your et money (the virtual currency used by the software) will continue to increase,

then you can buy other courses, so it's very interesting. There are quite a lot of courses. Of course, you can also buy more courses through RMB,

with continuous practice, your own level will be higher.

don't mention the advantages, download and experience it yourself.

PS: every time you practice, you will download a new course (even if you have already learned it), so you need to have network support, and you can't run on a single machine.
