850 miner parameters

1.

bitcoin mining machine is a kind of 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

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

2. 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.

3. At present, the market price of second-hand mining machine is quite different. We need to evaluate the service life and the aging condition of the parts in order to get the result.

4. I have bought many versions of interstellar miner before, but on the whole, the interstellar infinite K1 miner is OK. Compared with other features, the interstellar infinite miner has the advantages of low energy consumption, high configuration, advanced operating system, low noise and special mining methods. Low energy consumption: a bitcoin miner, the ant S9 miner, is 1700W an hour, while the interstellar infinite miner is 30W an hour. High configuration: 4G standard memory, Intel quad core high-speed CPU, built-in customized version of Intel motherboard, so that the running speed of mining machine is impeccable. At the beginning, it comes with 2000 + enterprise 8t hard disk, which wins at the starting line and takes the lead in mining. Advanced operating system: K1 (interstellar unlimited miner model) uses Linux system, which is stable, safe and powerful. Compared with windows, K1 is more suitable for development environment or actual proction environment. K1 has hot plug function that some miners don't have. The hot plug function facilitates the replacement of the hard disk, greatly improves the work efficiency, reces the damage probability of the mining equipment, increases the effective mining time of the mining machine, and improves the unit time yield of the mining machine. Low noise: K1 mining machine in order to meet the needs of customers at home mining, equipped with ultra quiet fan. Even if you dig at home, you won't be bothered by the noise of the miner. Mining mode: Mining depends on the transmission speed of uplink broadband traffic. Bitcoin and Ethereum both rely on CPU to mine. Both are chips, but the processing proceres are different. The interstellar infinite miner mines through the transmission speed of broadband traffic. I hope the great God will adopt it

5. When choosing mining machine, it depends on the company's ranking on the test network. If it is not in the top five on the test network, it is recommended not to consider it.

6. Level 1 Wuliangshan Jiange Jinghu Taihu Songshan Dunhuang Level 2 West Lake Level 3 Erhai level 4 Yannan level 5 Longquan level 6 Cangshan level 7 Yanbei level 8 Wuyi level 9 Shilin Xueyuan level 10 grassland Meiling Xueyuan

8. Proficiency alone will kill you. It's hard to practice mining skills. Mining skills, like cooking, require proficiency. Upgrading to level 6 requires more than 500 proficiency, that is, at least 500 mines need to be g. Here is a description of the growth of proficiency. If you dig a mine with the same skill level, you will be more proficient at one time. If you dig a mine with a lower skill level, you will be less proficient at two times. Due to the scattered distribution of mines on the map and the slow refresh speed, the practice of mining skills becomes extremely difficult. Mining consumes energy, level 1 mine is 2 points, level 2 mine is 3 points, and so on. It's not a big problem to limit our energy. After all, we can't go all the time to mine. After that, we can't practice and fight occasionally, and our energy will rise again
Where are all levels going to mine? As we all know, there are two adjacent levels of minerals distributed on the same map, and there are more low-grade minerals than high-grade minerals, which requires you to choose: first, the map with faster growth and proficiency, which can be g in both mines; The second is not to waste energy, only to dig the current level of mine map. I think the first method can be used in the early stage, and the second method will be used in the later stage
Xihu: Grade 1 and grade 2
Erhai: Grade 2 and grade 3
Yannan: Grade 3 and grade 4
Longquan: Grade 4 and grade 5
Cangshan: Grade 5 and grade 6
Yanbei: Grade 6 and grade 7
790 + is required for upgrading mining to grade 7.

9. There is a monster named wonder rock who can get pyroxene after being killed. This monster can appear in the forest of the holy land of the dragon in dimensional space
