bitcoin mining machine is the computer used to earn bitcoin
mining software is the algorithm of bitcoin
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
extended data:
bitcoin has the following six characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Worldwide circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

2. Yes, but it needs a good CPU
3. Buy the machine first! Machine algorithm can't dig to death!
4. First, we need to find a stable bitcoin mine pool which is easy to operate, and then connect to the designated server to mine through the mining client software. Take "BTC guide" website as an example. First open this website and click the user registration on the left. The registration process is relatively simple. You can enter the English user name, password and confirmation password
2 after successful registration, we will see a message like "your account has been successfully registered and logged in!" on the web page, It means that we have successfully registered and logged in
3 we can click the "dashboard" button in the upper left corner to see the whole monitoring status of the account
note: in this monitoring dashboard, we are most concerned about "total earnings", which is the bitcoin earned by our current account. In the future, as long as we open the website and enter the monitoring dashboard, we can see the relevant information of our account
4 next, please click "Settings" in the navigation bar of the page. In the settings page, we can set the e-mail address, bit wallet address, change the password, etc.
5 if we set the e-mail address in the account, if we forget the password or steal it in the future, we can restore the password through the set e-mail. First, enter our common email address in the "email address" column, and then click the "change" button
6. Next, a confirmation email will be displayed on the page to confirm that it has been sent to our previously set email
7. Then we open our email and find the email sent by BTC guide. Click the confirmation link, and then the page will show that our email has been successfully set
8. If we set email in the account setting, we can also set email notification for the behavior of mining miners. Find the "idle warnings" column on the setting page, click the drop-down list, select the time when you want to send the email, and then click the "change" button on the right. When we set 10 minutes later, if a miner stops mining, the system will automatically send a notification email to our email after 10 minutes. After receiving the email, we knew that the miner was on strike
9 in addition, we are more concerned about the "bitcoin wallet", that is, the wallet address. You don't need to set this address first. It's not too late for me to fill in when I really get bitcoin
10 after the account is set up, we need to set "worker". What is a worker? This is the login account name we will use later on the bitcoin mining client. The system will create a miner name for us by default. The miner name is composed of our registered account name, an underline and a number. For example, our registered account is XXX, and the first miner's name is "XXX"_ 1 "
11 if we want to set multiple miner names, enter a number such as" 2 "in the" create worker "column, and then click the" create "button to add a new miner's account name
12 in the worker settings page, we can also set the mining payment mode of the mine account separately. Payment method, i.e. mining payment method. There are two types to choose from, PPS and PPLNs. The difference lies in the mining mode and handling charge. The handling charge of PPS is 7.5%, while that of PPLNs is 3%. The system adopts PPLNs by default. If you want to change it, please click the "change" button under the payment method
13 in addition, we can also choose the difficulty of mining mode. If our computer has multiple graphics card GPUs or some special machines, we can set the miner's account name under the minimum difficulty
Step 2, download the mining client software
1 after we complete the registration setting, Next, please click "support" in the page navigation menu, and we will see the download link of the client< There are two types of mining client software:
bfgminer: command line operation interface, which can be downloaded directly
cgminer: it is also operated in the command line format, but the download steps are too complicated
let's take bfgminer as an example and click download as shown in the figure
2 then it will jump to the download page of mining tools. There are two formats of mining tools, one is 32-bit system, the other is 64 bit system. According to the number of system bits, download the corresponding tool version
3. The client size of mining tool is less than 5m, which is a zip compressed file. When the download is complete, locate and open the file. Click the right mouse button and select the "" option
4 here, I take paste extraction to the desktop as an example
Step 3, mining client software detailed settings
1 after opening the mining directory, double-click to open the "bfgminer" file under the directory
2 next, look at the BFG minier window and enter the address of the mine pool at the URL. The pool address can be seen in the BTC guide's support page, such as stratum. Btcguild com:3333 , press enter key
3, and then enter the miner's name set on BTC guide website after the user name, press enter key
4, and then enter at will in the password, as shown in the figure
5. Finally, you can see that many numbers are changing, It means mining. It is worth noting that the places marked in the figure indicate the speed of the current machine button
6 in addition to the current mining speed on the mining client software, we can also see the specific mining speed of each miner in the "active worker summary" list on the "dashboard" page of BTC guide website
7 If you want to close the mining tool, you can directly x drop it, You can also directly press the Q key to exit. If you want to open more, you can open another mining tool in the BFG miner directory< Step 4: cgminer command line client software
1 if you really want to mine, the official recommends that we use "cgminer", that is, to run it at the command prompt. Click "support" on BTC guide page, then click "cgminer" download link page, select the corresponding system version
2, then jump to cgminer download page and click the link as shown in the figure
3 and then select a version of cgminer. Here I download a Windows version as an example.
4 take the Windows version of cgminer as an example. After the download, unzip it to the computer.
5 open the cgminer directory, find "cgminer"
6. Double click "cgminer" with the mouse, and a command-line window will pop up, prompting us to enter the URL address of the connection server. Enter "stratum. Btcguild com:3333 ”, press the Enter key on the keyboard
7, and then prompt us to enter "user name", that is, the account name of the miner. Press the Enter key on the keyboard
8, and then enter the password. Press the Enter key on the keyboard
9, and wait for a moment, When the client and the service establish a connection, the machine will start mining
10 to quit mining, please press the "Q" key on the keyboard in the window

precautions
if you are using cgminer, the graphics card must support the display of general computing standard, otherwise you will not be able to mine.
2 after successful registration, we will see a message like "your account has been successfully registered and logged in!" on the web page, It means that we have successfully registered and logged in
3 we can click the "dashboard" button in the upper left corner to see the whole monitoring status of the account

5. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency. Virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. In 2013, the central bank, together with five ministries and commissions, issued the notice on prevention of bitcoin risks, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, which do not exist in the form of currency and legal currency. At the same time, digital money is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.
6. Zuk Z1 is equipped with a quad core processor of Qualcomm snapdragon 801, with a main frequency of 2.5GHz. The machine has built-in 3gb running memory and 64GB internal storage space, and uses a 5.5-inch 1920 × 1080 pixel full HD IPS liquid crystal display and 1300W + 800W combined lens are used to take photos, which can bring good display effect. At the same time, it is also equipped with 4100 MAH mobile phone battery, which can bring a good standby experience. In addition, the device also supports all Netcom, which makes it more convenient to exchange cards online.
7. Is bitcoin a good idea? No, bitcoin is a funny bad idea. It's a scam. fraud. It's not money. The economic assumption that is the basis of bitcoin ecosystem is ridiculous, and it ignores the knowledge accumulated for hundreds of years about how different currencies work together
fortunately, it is such a leaky system that it will probably never grow to a point where it will have adverse effects or impacts on the world economy
however, I feel it necessary to point out the problem
bitcoin is more like a data transmission system than a cash trading system. Well, the problem is that it doesn't make a deal by offering a digital cash deal in dollars, but by importing a whole new currency. So here we will ask, is this really desirable
one of the fatal problems: the distribution of initial wealth
when the Federal Reserve prints money, it will not issue millions of dollars of checks randomly to thousands of Americans. The work it does is: 1. Buy some other assets (usually US Treasury bonds) in the free market to inject more cash into the system than before; Or, 2. Lend money to the bank, the bank lends money to others, and finally spends the money
the important thing is that these people don't get money for free. They either sell their assets for cash, or borrow money to spend it and eventually pay it back (also paying interest)
the bitcoin system does not have a central bank to issue currency. It has an "algorithm" that allows bitcoin to be "mined" through a rather puzzling mechanism. Basically, it's randomly assigned to people who are early in the tasting season. It's a very good system for early entrants (free money!). It's a ridiculous system for real money, not to mention the obvious lack of expansibility (what happens if everyone mines all day long?) In order to solve this problem, the supply of bitcoin is algorithmically limited, which once again brings benefits to early entrants, but this leads to the second problem:
the second fatal problem: endogenous deflation
economics course time! Deflation results from the appreciation of currency relative to other commodities (such as the decrease of commodity prices). More directly, deflation occurs when people expect the currency to appreciate relative to other commodities, and the price trend continues to decline
question: if money is expected to appreciate, why do you spend it? Answer: Generally speaking, you don't spend money
the supply of bitcoin is set to slow down at a known rate. It eventually reached about 21 million. As shown in the picture
we can see the rate - well, I agree that if it is foreseeable inflation, it may not be desirable from an economic point of view, but it is reasonable. However, if it is to slow down the issuance, if you design a currency to subvert the world order, what you would like to see is this graph:
then what if there is at least a constant growth rate? You may be willing to do that, because that's the only way to adapt to more people using it
but bitcoin is not designed to be a practical currency, it is designed to make early entrants rich. Once again, it's a hoax
for a quick thinking experiment, we assume that more people use bitcoin compared with the growth of demand for bitcoin. In this way, we can expect the dollar price of bitcoin to rise rapidly. Now suppose I have a bitcoin, I also have a dollar bill, I am willing to buy a bottle of Pepsi Cola, which payment method will I use? Obviously, the devalued dollar should be spent more than the rapidly appreciating bitcoin
in the best case, the limitation of bitcoin supply will cause severe deflation, squeeze most of the business activities of bitcoin pricing, and connive at speculation in the trading market. If you are not willing to use it and others are not willing to use it, the so-called benefits of transparency and low transaction costs will not bring you any benefits< The third fatal problem is the lack of convertibility. People have a misunderstanding about the so-called intrinsic value of money. In fact, there is no so-called intrinsic value of money. The nominal value of money is limited to the other money they can trade for. One dollar is equivalent to a certain amount of euro, one euro is equivalent to a certain amount of yen, and one yen is equivalent to a certain amount of dollar. One dollar can be stored in the bank, change a certificate of deposit, and then the certificate of deposit can be changed into one dollar. It can be turned into a commercial or personal check and then into cash or deposit. When you travel, it can be changed into a traveler's check in yen or euro. If you have to pay for sandwiches, the sandwich shop also charges because the money can be converted into something else. It's a wonderful circular balance.

8. First of all, because the computing power of bitcoin is already very high, it is impossible to dig bitcoin by using a computer. You must use a special miner to dig bitcoin. If you buy a miner, it usually comes with installation and debugging instructions, and you can configure the parameters according to the instructions
9. Because your mining speed is too slow, only 3mh / s, and the unit on this website is GH / s, converted to 0.003gh/s,
of course, it can't be displayed
the setting is OK
it's not recommended that the mining speed is too slow, so it can't be g at all
if you need, I can recommend a website for you
