The model of bitcoin miner

1.

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

2. The miner is composed of chips, cooling fans, batteries and other components. The "chip" is the core component, which determines whether the miner can dig out more digital currency more easily. Mining machine chip manufacturers need to have a very strong R & D strength, need to race with the rising global computing power, test the ability to integrate with science and technology. Therefore, it is very important to select powerful brands and teams
at present, there are two most famous bitcoin miners in the world: ant miner of bitcoin mainland and Avalon miner of Zhang Nangeng. The latter is also the inventor of the first ASIC chip miner in the world
when choosing mining machines, we should first look at computing power, second look at power consumption, and third look at historical reputation
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of mainstream bitcoin mining machines is 14T, that is, 14 * 10 ^ 13C hash collisions per second
power consumption is an indicator of power consumption when the mining machine is running, which is directly related to the cost of mining. Under normal circumstances, the mining machine will operate 24 hours a day, so even if the power consumption of different types of mining machine is very small, the power cost gap is very large
the historical reputation represents the stability of the miner's operation. You can know the overall user evaluation, after-sales service and whether the prepayment miner can deliver on time from different purchase channels
to say that the simplest way is to directly select the latest spot miner model. Because the latest mining machine power consumption will be relatively small, computing power is relatively high, input-output ratio is the most cost-effective
we need to remind you that the noise of the miner is relatively loud, which is also a tough injury of the miner.

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.

5. Mining machine manufacturers have gone through several major reshuffles. At present, the more active mining machine manufacturers are Ajie mining machine, ant mining machine, and of course, several well-known foreign mining machine manufacturers. Avalon, the earliest miner in the coin circle, and roast cat have disappeared. On the one hand, the upgrading speed of mining machinery is too fast, on the other hand, the strength of the R & D team has been unable to keep up with the needs of the times

however, each miner has its own advantages. It doesn't matter whether it's good or bad. The scope of application is different. Some mining machines have high energy consumption, high computing power and low price, which are suitable for users with low electricity price; Some mining machines have low energy consumption, high efficiency, high price and high electricity price. Of course, you can also go to bitcoin home to check the recent mining related reports.

6. Current situation:
RMB will continue to depreciate. The current price of US dollar against RMB is 6.7572. In the future, it will be 6.9000 and 7.1550, or even 7.42 or higher. It is only a matter of time. One US dollar will depreciate by 2-40 cents, or even more, and 10000 US dollars will depreciate by 20000-40000 yuan, It's equivalent to your current 67500 yuan. In the future, it will be equivalent to your current 47500-27500 yuan. As long as you invest in RMB, it will be the result. It's not like this if you change it into US dollars. Changing it into US dollars will only make the RMB in your hands appreciate! Now 67500 is converted into 10000 US dollars, and after a period of time, it will be 87500-107500 RMB yuan when it is taken out and then converted into RMB. This is the fact
now there is a better project. It is the first to make money by changing your RMB into US dollars; Second, we should make our robust EA, with an average monthly return of about 5% and a maximum principal risk of 10%. Of course, there are other strategies for EA. We should make it robust according to the risk preference of investors. After all, most investors are risk averse. At present, the operation of robust EA has been nearly 10 months, and the international tripartite financial website has been publicized for more than 3 months. Hundreds of customers are using our robust EA proct. The average monthly income is about 5%, and the maximum principal withdrawal is about 3%, which is very robust
the current stock market is not optimistic, and there is not enough action in the market, even before the bull market. Even if you can get 30% of the annual stock return, the RMB will continue to depreciate, and when you pay out, it will be far less than 30% of the return; I suggest that we can choose to invest in foreign exchange at present. We can find a reliable and qualified foreign exchange platform to deposit our money. Our platform is very good. Capital security, trading environment, back office management system and our service are all great. Even if we don't do our steady EA, we only deposit it in US dollars and withdraw it after a period of time, your RMB will appreciate! Compared with stock speculation, bank financing, various types of RMB financial procts, value preservation and appreciation much more
if RMB is converted into US dollars and deposited in the bank, each person will only have the maximum amount of US $50000 per year, and the payment proceres are quite troublesome.

7. It's OK in China. It's only necessary to choose a good one for steady development. Dcpro can be regulated formally.

8. First of all, the computing power, then the power consumption. At present, the models of mining machines on the market are not complicated. Ant mainland has the largest market share. The performance of mining machines is quite stable. Avalon mining machines have good performance stability and strong rability. The power consumption depends on the local electricity bill. At present, it is more than 40 cents and can not be done. It is basically maintained. Indivial mining machines still have certain profits, and bitcoin has increased greatly, Don't venture forward, bullish don't see the temptation in front of you, short-term can!
