Picture of bitcoin

1. You use the bitcoin miner. Anyway, I use the krypton miner to dig, which makes me earn a little

2.

Find the code on the bitcoin system, and you can dig bitcoin if you find the code

every other time point, the bitcoin system will generate a random code on the system node, and all computers in the Internet can search for the code. Whoever finds the code will proce a block, and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards

characteristics of bitcoin

The total amount is limited, only 21 million BTC

2. Anyone can issue bitcoin, but it is more and more difficult

3. Compared with the central bank currency, it is safer and almost impossible to be stolen

The transaction process is completely anonymous and cannot be traced

3.

Bitcoin is the first distributed virtual currency

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

extended information:

as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code

in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred

however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties

naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes

it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations

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

< EM > Figure 3: Mine Map (scale of tens of thousands of mining machines) < / EM >

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:

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

5. Seeing the question of the subject, I think the subject is still interested in science and technology finance, which is very good. Now I'll answer it in common language
first of all, bitcoin is not created one by one. Bitcoin is made up of one account book after another. As long as you can record one account book, the system will reward you accordingly (starting from 2009, after four years, one will reward 50 bitcoins, another four years, one will reward 25 bitcoins, and so on), Because the account book records the transaction information, the transaction fees generated by the transaction also belong to the bookkeeper. Such a good thing, of course, everyone wants to keep accounts. At this time, the more wonderful thing will come. The system will put a mathematical problem every ten minutes. Whoever works out first will have the right to keep accounts. They can keep accounts and get bitcoin generated by keeping accounts
then the generated bitcoin will be saved in your wallet address. You can transfer the bitcoin in the address to EXX. There are not only bitcoin, but also more valuable currencies. Of course, you need to choose
investment is risky, and we should cherish it

6.

Just now, as of 23:00 on March 3, bitcoin is now 71976 RMB. At the beginning, when I knew it was very expensive, I also asked this question, how to dig this thing

many mining machines with large amount of calculation will proce a lot of heat in the operation, so they need to consume a lot of electricity for cooling

of course, mining can also be carried out on a small scale with a few mining machines. At this time, you can join the mine to dig with everyone. No matter who digs in the mine, everyone will distribute according to the speed of throwing dice, which can ensure a more stable income

at present, there are many people digging bitcoin, so they have high requirements for the computing power of mining machines. At present, it costs thousands of dollars to dig a bitcoin. Therefore, we should not blindly evaluate the income risk before making a decision

I'm brother Xiaoyu. If you have any questions, please pay attention to me and leave a message below for us to discuss

7. For bitcoin, don't invest any more. It's a complete gamble. Remember, don't participate, especially at this stage. The threshold itself is very low. Bitcoin is not money. It can be divided into any large unit, such as 0.0000015 bitcoin. I don't know when the concept of bitcoin was changed into bitcoin. It can be worthless at any time

8. To make this kind of virtual currency, we should be prepared to lose money. Only two out of ten make money, so you know.

9.

On the front of the coin are printed "people's Bank of China", "1 yuan", Chinese phonetic alphabet "Yiyuan" and "2004" year number; The pattern on the back is children and the Chinese Zodiac elements, and "Jiashen" is printed below

in order to welcome the arrival of Jiashen year of the lunar calendar, the people's Bank of China announced on January 6, 2004 to issue a set of commemorative coins to celebrate the new year of the monkey. The front of the coin consists of Chinese and English characters of "1 yuan" and the year number of "people's Bank of China" and "2004" above the inner edge. On the back of it is a picture of a little boy wearing traditional Chinese clothes flying a "Kite" happily. Now the market price is about tens of yuan

10.

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
