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

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

5.

The steps are as follows:

1. Add a mine pool. 2. Download the software. 3. Start digging after setting

however, it is suggested that the building owner give up and dig bitcoin mainly depends on the GPU, that is, the processing chip on the graphics card. The home computer integrated graphics card can't be g at all. If the independent graphics card is NVIDIA chip, it's basically useless, because the most computing power is 160m / s

according to the income ratio, the calculation power of the machine is less than 8g / S (8192m / s), even the electricity fee is not enough, so it's meaningless to dig with a home computer for more than ten yuan a month. If you really want to dig, you should buy a mining machine

6. I suggest you don't go. I'm Lenovo. I g more than 10000 computers for a week and found 0.000034 bitcoins. It's not enough for electricity. If you want to speculate, it's better to go to the okex exchange.

Beijing, November 13 (reporter Wei Xi) - the people's Bank of China publicly responded to market rumors on the 13th that it has not issued legal digital currency, nor authorized any asset trading platform to trade

recently, it is reported that the people's Bank of China has issued legal digital currency, and some institutions falsely use the name of the people's Bank of China to trade relevant digital procts under the title of "DC / EP" or "DCEP" on the digital asset trading platform

in this regard, the Central Bank of China has made it clear that legal digital currency has been studied since 2014 and is still in the process of research and testing. Neither "DC / EP" nor "DCEP" traded in the market is legal digital currency, and the launch time of legal digital currency transmitted through Internet is inaccurate information

extended information:

the people's Bank of China reminded that the current online dissemination of the so-called legal digital currency issue, as well as the behavior of indivial institutions trading on the asset trading platform by using the name of the people's Bank of China to launch "DC / EP" or "DCEP", may involve fraud and pyramid selling. Please raise the public's risk awareness and do not believe it, Prevent the interests from being damaged

To this end, Mu Changchun, director of the digital currency Research Institute of the Central Bank of China, also launched a seven lecture open class to solve the doubts and doubts of the outside world. Mu Changchun said frankly in the open class: the functions and properties of the central bank's digital currency are exactly the same as paper money, but its form is digital

"our definition of it translates into 'digital payment instrument with value characteristics'". The digital currency of the people's Bank of China should adopt a two-tier operation system, that is, one is the central bank to the commercial banks, the other is the commercial banks or commercial institutions to the ordinary people End)

8. CP and CV are two different thermodynamic parameters; The former is equal pressure heat capacity and the latter is equal volume heat capacity.
9. It's said that it's becoming more and more difficult to dig. Ordinary people can't afford the amount of computation needed. Don't think about ordinary computers. Besides, the value of bitcoin fluctuates violently. Don't put in the electricity bill
