Mining machine does not generate revenue

1. Firstly, the cost of bitcoin mining can be divided into three parts:
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.

2. According to the current total computing power and the current growth rate of total computing power, it will take about 250 days to dig a bitcoin

3.

IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines

in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine

because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used

of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery

extended data

the reasons why it is not recommended to invest in IPFs are as follows:

1. IPFs technology is too early to be commercialized

IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs

There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological value

as a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened

the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state

It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems

The ecological application space of

IPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling

4. digital currency
unlike virtual currency, digital currency is neither bitcoin nor q-coin! That is to say, it is different from virtual currencies such as bitcoin and Ethernet
virtual currency can only be closed in circulation on the network, just like Tencent's q-coin and Huixin cloud software collaborative instry ecological chain platform, they can only be used for their own procts. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal digital currency. As for legal digital currency, there is no unified international definition. Yao Qian, deputy director of the science and Technology Department of the people's Bank of China and head of the preparatory group of the digital currency Research Institute, believes that the digital currency researched and issued by the people's Bank of China is indexed RMB. From the perspective of national schemes, it belongs to legal encrypted digital currency, which is not only a payment tool but also a currency. Correspondingly, virtual currency is also called illegal fixed digital currency. Li Lihui, head of the blockchain working group of China Internet Finance Association, once said that digital currency must have legal status, national sovereignty endorsement, and clear responsibility subject of issuance. Virtual currencies represented by bitcoin and ethereal currency have no country, no sovereign endorsement, no qualified issuers, and no national credit support. These are not digital currencies
digital money is not equivalent to virtual currency
since digital money can be used for commodity trading, is Alipay and WeChat payment a kind of digital currency?
Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. These are all payment methods based on electronic accounts, which are in essence just a process of informatization of legal currency, not digital currency in a strict sense. For example, the amount of Alipay or WeChat transactions is essentially banknotes on bank accounts, but it is electronic form. The "100 yuan" displayed on the mobile phone will correspond to the real 100 yuan in the bank.

5. This simple, first enter NB cloud mine's official website, and then register, and then choose the right mining machinery procts, it's OK. I'm also mining here now. It's very safe. The monthly net income rate is also very good, which is 3% - 10%. In addition, Nb cloud mine doesn't fight for character. It rents according to the number of shares. For example, if 180 days is calculated as the income of a miner, 90 days is 1 / 2, so the income is different.

6. That's because the leasing and income of Nb cloud mine's mining machinery is not calculated by the number of units, but by the shares. For example, the output and income of 180 day mining machinery is calculated by the complete mining output and income of one mining machinery, while the income of 360 day mining machinery is calculated by the mining income of two mining machinery, The profit of 30 day mining machine is one sixth of the profit of mining machine.. If you have any questions in this respect, you can ask them at any time

7. I agree with you very much. You can't buy the miner blindly without knowing the source of income.

8. Buy mining machine, basically can guarantee as long as there is computing power can be directly proportional to the income. In the early days of mining, because the number of miners was not very large, CPU was widely used in mining, which could be regarded as the "trillion" level. With the increase of mining population, CPU obviously can no longer meet the needs of miners. At this time, the graphics card mining with greater computing power and stronger universality was born, and the computing power was pushed up to the "100 trillion" level. Interstellar bit miner can pay more attention

9. Fil coins are still rising. Now it's a good time to buy a miner to dig coins. Previous experience has proved that this investment can make money, and the amount of income is nothing more than the choice of miner. The interstellar ant miner technology is supported by alicloud, with a short packaging period and a high return on miner income. You can choose it by reference. You can search for it yourself,

10. Of course, the mining machine determines the computing power, and the computing power determines the user's income. At present, the mining machine that can be trusted on the market is the hummingbird H1 of interstellar bit.
