Seeking to rent Ethereum mine
Miner components include CPU, GPU, motherboard and hard disk, similar to a high configuration computer with a hard disk. Self assembly mainly depends on which aspect of hardware performance you want to highlight
mining machine has computing power, display card mining machine and storage mining machine. Daotong storage has long been concerned about the dynamic and hardware supply of mining machine, and its own components will be cheaper than those of the manufacturer< br />
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

mining machine risk
1. The problem of electricity charge
in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge 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
2. Hardware expenditure
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
3, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
to put it simply: if you are only the holder of eth, you don't need to make any preparation for this upgrade.
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.
hope to adopt
because the network wide computing power required by this kind of token is not high, the probability of hash collision of the computing power of personal computer can find out the answer in a short time, so as to obtain block rewards. However, this kind of token generally has little value or high risk, so it is not of great significance< br />

mining risk:
1. Electricity charge problem:
if the graphics card "mining" needs to be fully loaded for a long time, the power consumption will be quite high, and the electricity charge 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.

2. Hardware expenditure:
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also on the battlefield. ASIC is specially designed for hash operation, and the computing power is also quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the electricity cost is also lower. It is very difficult to compete with these mining machines, This kind of machine costs more
3. Currency security:
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
4. System risk:
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income
however, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners.
