Bitcoin excavator model

1. 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.

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

< UL >

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

mining difficulty improvement at present, our machines can meet the market demand

3. There is no other use at the moment. The income in other currencies is average. If you think bitcoin will rise in the future, you can always dig bitcoin. If you and I have a future in other currencies, you can also dig them

4. Now there are professional mining machines.
search online.
it's hard to dig a coin a day with your own equipment.
plus the cost of electricity,
there are suggestions for mining machines on the Internet

5. 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.

6. CP and CV are two different thermodynamic parameters; The former is equal pressure heat capacity and the latter is equal volume heat capacity.

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

8. IBM and bitcoin are almost virtual currencies. If they are valuable, they are worthless. It is not recommended to invest in this kind of virtual currency, so as not to be cheated by criminals
it is suggested to invest in the spot form of yellow / gold / crude oil. Yellow / gold has always maintained its value, and crude oil as war savings can not go anywhere. Recently, the market has fluctuated a lot. It's still easy to make money.

9. 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!

10. Naturally, the total computing power of five computers is 1000g. I don't think it's necessary to elaborate on this principle at all. If you combine it with the principle of computer operation, it will come to light naturally. However, it's better not to play with bitcoin at this time. Any new thing launched is that people who eat crabs first take advantage of it, and those who come later will have a good look at it. If you want to just play, if I don't say that you want to make money, it's not very interesting.
