5T miner
CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining
while mining chips are updated, The change of mining speed is:
CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5thash / s) → large scale cluster mining (3.5thash / s * x)
mining speed, which is called computing power in professional terms, is the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return
in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes
in order to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. They have to guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin
so far, the highest 1btc price in bitcoin history is about $20000, with a market value of more than $60 billion.
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.
Ant mining machine S9 how much a day to dig
S9 computing power 13.5T, the current network computing power 6.39eh/s, 1e = 1024p, 1p = 1024t, 1t = 1024g, a S9 a day to proce bitcoin is [13.5 / (6.39 * 1024 * 1024)] * 180 ≈ 0.0036btc< br />
1、 Mining principle
at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining
looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:
CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)
mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return
in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes
to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin
Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability
there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises
2. Mine pool
in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance
the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day
3. Cloud computing power
in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative
Mining income and risk mining income can be calculated by the following formula:Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee
if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee
Mining risks are as follows:
< UL >at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle
mining difficulty improvement at present, our machines can meet the market demand
the risk of power outage

take an ant s9-13.5t mining machine as an example, the power is 1.35kw
the power consumption of 24 hours a day is: 1.35kw * 24h = 32.4kw/day
according to your local electricity charge, assuming that the electricity charge is 0.5 yuan / kWh, 32.4 * 0.5 = 16.2 yuan / day
then an ant s9-13.5t mining machine can consume 32.4 kwh a day, The daily electricity charge is 16.2 yuan

According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts
extended data
unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
