Look at computing power
we are also most concerned about Suan Li Gang. We need to see whether a company has strength, not only depends on the Suan Li level, but also depends on the single-T burst rate and 24-hour mining efficiency. After all, the amount of money is directly related to our interests
with the coming of the main network of filecoin, the popularity of filecoin continues to increase worldwide, and the price of fil futures has risen rapidly since late May. Some people say that the price of fil currency will soar after the main network of filecoin goes online
we also know that from the perspective of filecoin allocation model, filecoin issued a total of 2 billion pieces, of which 70% were awarded to miners, and the 70% were used to provide data storage services, maintain blockchain, etc; The remaining 30% goes to teams, investors and foundations, with a six-month to six-year unlock period. It can be seen from the distribution model that there were few circulating tokens in early fil, which is also the reason why many people speculate that fil will soar after it goes online
let me give you some suggestions on how to participate. What are China's IPFs companies? How to choose the company and mining machinery
(1) first of all, hardware. We must pay attention to cost performance, rather than blindly choose high or low price. High price does not necessarily bring you income matching with the price. Low price may not be able to participate and lose money
(2) the second is to pay attention to mining strategy. Professional and efficient mining strategy can improve our mining efficiency. Good mining machine with a good mining strategy, you can get a good profit
(3) the third suggestion is to have a professional operation and maintenance team. Our mining machine is placed in the professional IDC room, and we also have our own professional operation and maintenance team, which is of course no problem
if you want to manage by yourself, you must consider environmental factors, such as bandwidth, operation and maintenance, etc. Professional things to professional personnel to do, in order to get better benefits. Another is that in the early stage, the storage is provided by the government or itself, but in the later stage, if the network wants to generate real market storage orders to obtain effective computing power, it also needs a special trading network to provide this service. This has higher requirements for the storage environment and operation and maintenance
(4) the fourth suggestion is to maximize the income of capital allocation. How to understand? That is to say, don't excessively pursue high performance and high storage capacity, because it takes a long time to accumulate effective computing power in the early stage. If a large number of hard disks are invested in one time in the early stage, which takes up funds, but has no effect on the improvement of income, it is a waste. Instead of this, it is better to buy more mining machines in the early stage, and expand the capacity when the storage is full in the later stage. Only in this way can the interests be maximized with the same investment.
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.
Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

Bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners
advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to
the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)
people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)
I hope I can help you
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 the mainstream bitcoin miner is 14T, that is, hash collisions of the 13th power of 14 times 10 per second
power consumption is an indicator of the power consumption of the miner ring operation. Electricity consumption will have a huge relationship with mining costs. Generally, a miner will operate 24 hours a day to excavate, so the power consumption sometimes seems to have a small difference, but in fact, the cost gap is relatively large
here is another little knowledge, that is, digital assets of the same algorithm can be mined by the same miner. For example, bitcoin miner can also dig bitcash, Ethereum miner can also dig Ethereum classic
for more professional knowledge, it is recommended to consult the honeycomb miner. There are professionals to help you select and answer for you. The boss comes from the fire coin, and I feel reliable after personal experience.
More than 500W power supply
sapphire rx580 full load power to more than 200 watts, plus CPU and other hardware power consumption, need more than 500 watts of power supply
If the power supply is500, it is necessary to pay attention to whether it is rated power. The value of rated power is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical appliances may be damaged; If the actual power is less than the rated power, the graphics card can not operate normally
extended data:
the power of power supply can be divided into rated power, maximum power and peak power
rated power: the ambient temperature is between - 5 ~ 50 ℃, the input voltage is between 180V ~ 264v, and the power supply can stably output power for a long time
maximum power: at room temperature, when the input voltage is between 200V and 240V, the power supply can stably output power for a long time, and the maximum power is generally about 15% higher than the rated power. For example, the rated power of Xingu nuclear power 325pq is 250W, and the maximum power is 287w, which is close to 300W
peak power: the maximum power that the power supply can achieve in a very short time, and the time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, which is not a definite value, but the peak power can be very large, which is very easy to mislead users. For example, the rated power of Xingu nuclear power 325pq is 250W, and the peak power reaches 350W. Obviously, only the rated power and maximum power have practical significance
