the answer is yes. Bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone may participate in the proction of bitcoin. But bitcoin is not issued in unlimited quantity. According to calculation, by 2140, the total amount of bitcoin will reach the upper limit - 21 million. Recently, according to the data from blockchain.info, unless there is an accident, the 17 millionth bitcoin is likely to be g up in the future
it needs to be clear that each newly g out bitcoin block will generate 12.5 new bitcoins, and a new block will appear in the bitcoin blockchain every 10 minutes, so about 1800 new bitcoins will be generated every day. As the reward is reced by half for every 210000 blocks generated, mining becomes more and more difficult, but this does not mean that bitcoin mining machines can no longer dig bitcoin. In addition, it needs to be made clear that bitcoin will not stop running when it proces 21 million bitcoins, so even if the 1700th bitcoin will be g out, there are still 4 million bitcoins waiting to be g out. Even if it is more and more difficult to dig out bitcoin, it is not impossible. It is said that the new routing machine that originally g out digital gold will also launch the function of digging bitcoin in the near future. Compared with thousands of professional bitcoin mining machines, the new routing machine is more user-friendly in price and less difficult in mining
in the future, we believe that although bitcoin has gone a long way, bitcoin still has a long way to go.
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

this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
At present, bitcoin needs to be g by professional mining machines. 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
according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation
extended data:
because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners
the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin
Introce the reward mechanism of bitcoin system. Bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
