BTC cloud mining
Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, 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
-
all public cloud manufacturers explicitly require that they are not allowed to use the cloud server for mining, otherwise they will be banned
-
GPU is mainly used in mining. At present, GPU servers provided by public cloud manufacturers are more expensive, which is not cost-effective, so it is better to use special chips
< / OL >
of course, some hackers intrude into the server through vulnerabilities, implant mining programs and scripts on it, and carry out mining operations, but this is illegal in itself
at present, bitcoin and dada are all traded on the trading platform. When I played, I didn't want to mine any more, and I didn't buy any mining machine, so I didn't seize the opportunity, which is a big regret in my life
hope to adopt.
Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost
therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin
bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment

bitcoin plummeted by more than 10%:
earlier on January 11, bitcoin once fell to $37000 / piece, the lowest to $35141, and the biggest drop in the day was more than 10%. According to the data of bitcoin home.com, the amount of burst positions in the past 24 hours reached US $1.165 billion (about RMB 7.530 billion), and a total of 115138 people burst positions within 24 hours
for the sudden drop, some netizens said: "what should come will come.". Cautious investors said that such a high position, I first clearance, short about
Mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
extended data:
shortcomings
first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless2 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
tools / raw materials
PC with independent graphics card
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.
