Bitcoin mining efficiency
mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K
now the basic unit is GH / s, and several hundred g mining machines are very common
[bitcoin mining machine]
bitcoin mining machine is a 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
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
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.
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
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
however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing
generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated

look at
1. First of all, as a node mine pool, the mine pool construction itself needs to add node files, which show the number of connections under the bitcoin wallet. After adding nodes, the number of connections can reach dozens or even more, depending on how many nodes you add, effectively recing invalid share
2. How to fix the calculation difficulty of mining equipment for miners? Set it in your mining equipment startup bat
for example, if your single mining equipment is 10g, you can add
/ 1000 + 10 after the user name (wallet address) in the bat file. For example,
- U
/ 1000 + 10
- P
1 in my bat, what does that mean? That is to say, your device is 10g computing power, and you use a fixed difficulty of 10G for mining in P2P pool. If you are a 1g device, write / 1000 + 1 at the back, so the difficulty is fixed and the efficiency of the device is effectively improved.
Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost
therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin
bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment

extended data
bitcoin plummeted by more than 10%:
earlier on January 11, bitcoin once fell to $37000 / piece, the lowest to $35141, and the biggest drop in the day was more than 10%. According to the data of bitcoin home.com, the amount of burst positions in the past 24 hours reached US $1.165 billion (about RMB 7.530 billion), and a total of 115138 people burst positions within 24 hours
for the sudden drop, some netizens said: "what should come will come.". Cautious investors said that such a high position, I first clearance, short about
the computing power and block output of the whole network can be seen here http://www.taobtc.net/
a lot of computing power is wasted. The reason for this is also from the structure of the P2P pool. The P2P pool node will automatically adjust the difficulty of the pool according to the computing power of the workers' mining equipment. This process is quite fast, and the difficulty will be adjusted every few minutes, As a result, the mining equipment is easy to report errors, that is, it generates a lot of R, which reces the efficiency. The P2P pool is a PPLNs mode. You need to submit an effective share to get profit. After submitting an effective share, you can get all the blocks generated within 24 hours. The difficulty of effective share is relatively large. What I reflected in my pool is that 1g of computing power can't dig effective share at all
