Bitcoin mining in Iceland

1.

Bitmine is real

bitcoin is proced by mining. Every 10 minutes, the miners of the whole network work out an arithmetic problem together. Whoever works out the answer first is equivalent to digging into this block, and the miner can get the bitcoin reward of system rebirth

after bitcoin is g in the mine, the income is distributed according to the proportion of the mine's computing power, so as to ensure a more stable input-output

every other time point, bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate 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

2. Mines are everywhere. You can mine them in your own home, as long as you have equipment. This year, domestic mining has been banned, but some relatively large mines have moved to foreign countries. Now Iceland can be said to be the largest mining area in the world
let's talk about the output. It's not as good as before
with the increase of computing power in the whole network, the proportion of computing power owned by miners in the whole network has decreased
the generation speed of bitcoin is slowing down. When bitcoin was born in 2009, each reward was 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 bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. In theory, bitcoin's mining speed has halved in four years
in addition, the equipment investment and electricity charges in the early stage are very expensive
the front runners have already started to drink soup. Want to know the latest information and market of currency circle, exchange. Focus on the mustard circle
hope to adopt

3. Cloud mining is an investment project that any country can do. It is to mine bitcoin and other virtual currencies through real mining machines, and increase the computing power by recharging. The higher the computing power, the faster the bitcoin mining speed, and then the platform and users share the profits equally. How much do you invest? You can get about 30% profit in a month. I invest in CLD cloud mining
the details can be found in the space

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
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.

5. The price of bitcoin has gone up abruptly, and the old miners who left the mine have begun to return. Many new people have also poured into the mining instry. However, the price has gone up, and the difficulty of mining bitcoin is also rising. How can we make money from mining now
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.

Icelandic Prime Minister katerin jacobsdotil was on the same flight after a man was arrested for stealing hundreds of bitcoin computers and escaped to Sweden on a plane

According to the surveillance video, Stefansson appeared at kevlavik International Airport, 95 km away from sonn prison, boarding and leaving the country that morning. Although Iceland has not joined the European Union, it has joined the Schengen zone, where member states are visa free and border checks are cancelled. Therefore, the airport is unlikely to require him to show his passport

A spokesman for the Swedish police said the arrest had not yet been carried out and that his Icelandic counterparts had informed the situation and issued international wanted notices

The virtual currency robber who stole hundreds of computers flew abroad after his prison break, and there was the prime minister on the plane. This is not a Hollywood blockbuster, but a real prison break in Iceland. Iceland's prime minister katerin jacobsdotil was on the same flight after a man was arrested for stealing hundreds of bitcoin computers and escaped to Sweden on a plane

The Swedish police spokesman said that the arrest has not yet been carried out, and his Icelandic counterparts have been informed of the situation and issued international wanted notices

in February, Icelandic police arrested 11 people including Stefansson, accusing them of stealing about 600 computers used to mine the encrypted electronic currency "bitcoin" from December last year to January this year. The total value of these computers is about 200 million kronor (about US $2 million), a record amount of criminal cases in Iceland. Icelandic media called it "bitcoin robbery"

Before Stefansson escaped from prison, 22 people were arrested, but the stolen computer was still missing

"Iceland is too small, most of the escaped prisoners are drunk, Iceland has no underworld and underground world, so generally no one escaped." Local police said

Virtual currency seems to make people rich overnight, such as bitcoin. At the beginning of the year, it cost a few yuan, but now it costs US $50000. Not all virtual currencies are bitcoin. It's better to be cautious. Now many friends want to invest in the digital currency of the blockchain and join the army of overnight wealth Red wine and other goods are given away by the company; Dark blue integral;, At the same time, points also have consumption value-added, which is returned in the form of points. Points can also be converted into virtual currency of the trading platform, namely & lt; Beilan coin;, Virtual currency can be traded or withdrawn on the trading platform, and it can rise or fall

shortly after the company's operation, it invited another nickname & quot; Fengshen & quot; Network operator, joint operation & lt; Dark blue integral & quot& ldquo; Beilan Coin & quot; Network platform fund-raising project, behind the beautiful gimmick, is a fraud of illegal fund-raising

in order to attract victims into the trap, put on appearances, buy luxury cars, expand false publicity and attract investors

later, e to the conflict between shareholders, the operator was reported and arrested by the public security organ, the company project finally collapsed, and this illegal fund-raising case graally surfaced
