Personal computer virtual currency mining

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

2. As a blockchain researcher, many new people often ask this question. In fact, there are two main ways to obtain bitcoin. The first is to purchase bitcoin directly from the corresponding digital currency exchange; The second is to mine for bitcoin

first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high

in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu exchange, one of the leading exchanges in China, has been in use for nearly two years and is still very stable and safe.

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

Some new virtual digital coins can be mined by computer, such as eth, Zec, Monroe, XRB, etc

because the whole network 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 the block reward. However, this kind of token generally has little value, or has no high risk, so it doesn't mean much

extended data:

mining risk:

1. Electricity charge:

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 mining has a considerable expenditure

in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display 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

5. Software and hardware come second... If you can't afford the electricity charge, you don't recommend yourself to mine by computer.
with the current market price and quantity of mining, those who don't go into the mining pool are g by yourself in places with subsidized electricity charge, such as hydropower stations and agricultural pumping stations. Civil electric mining is at a loss

6. At present, the global unified computing difficulty of bitcoin is 2621404453 (it is expected to change in two days). It will take more than 2000 years to work out a bitcoin and a 2.5GHz CPU, which is ridiculous. Home computer can dig out a bitcoin in three months, I don't know what age it is

7. Forget it, the mining cost is very high. First of all, it requires configuration. In addition, it costs a special graphics card. It also costs electricity. The code reading operation runs with computers all over the world. First, it calculates the probability problem, and then + cost + time. Mining is not recommended. Now
it used to be better, but now bitcoin is no longer what you want to dig.
many people have begun to sell mining machines

8. Mining is the most primitive "exploration method" to obtain digital currency. In essence, it is to solve a complex mathematical problem with computer. If blockchain is compared to a large account book, the block in which is a page in the account book, and all miners are bookkeepers, the process of mining is bookkeeping, and also to maintain the normal operation of the whole network
the process of mining is very simple. Take bitcoin as an example. Every 10 minutes, all the miners work out a math problem together. Whoever works out the answer first is equivalent to digging this block and getting the corresponding bitcoin as a reward. Mining equipment is the first to use computers. With the rising price of bitcoin, more and more people participate in mining. CPU mining has graally turned into a professional graphics card. In recent years, it has become a specific mining machine. This evolution is e to the problem of computing power. As I said just now, mining means "all miners work out a mathematical problem together." the higher the computing power, the stronger the hardware computing power and the faster the speed. Suppose that the computing power of the computer is 1, the computing power of the graphics card is 5, and the computing power of the mining machine is 100, then the mining efficiency of the mining machine is 100 times that of the computer, It's almost impossible for computers and mining machines to dig bitcoin together

warm tips: investment has risks, so we should be cautious in choosing. According to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have monetary attributes such as legal compensation and compulsion, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
