Calculating power by digging a gate
1. Guiminer
guiminer is a powerful and easy-to-use bitcoin mining software for Windows system. The software is small in size and friendly in interface. As long as the user's CPU or GPU is strong enough, it can create a new miner on the interface and mine independently! In addition, guiminer is free software
the biggest advantage of XmR is that it can use CPU to dig holes and revitalize rendant CPU resources... Using graphics card to dig XmR, according to the current price, it may not be able to recover the cost!
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.
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
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
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
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 valueas 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 ofIPFs 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

F
moreover, the show is broadcast by LETV members alone, which shows its influence! General members alone play will affect the audience rating, moreover, the audience of LETV members is less, it is difficult to spread out
thirdly, the plot structure of the play is unique. Instead of adopting the traditional mode of "domineering president" and "strong man and weak woman", the hero Yu wenle turns into "otaku", and the heroine Yang Rong he pursues is a rich family. But maybe the theme of modern love story is ordinary, and the topic of strong women and weak men is not very attractive
there is no super brand, no big promotion, no novel plot! We've seen it, but to tell you the truth, now that I know something about it, I still don't want to see it
I don't know if you've seen it or not. This is also my own opinion!
