Multi picture BTC on the same screen
mining steps:
(1) Download bitcoin official client, click here to download bitcoin official client
(2) after installing the client, start the client, and the client will start to synchronize network data within 3 minutes after startup. Because bitcoin data is huge, it may take several hours (depending on network speed and computer performance). The picture shows the client synchronizing network data:
please make sure that your C disk has more than 10GB of free space. If the C disk is not enough, you need to set the data to D disk or e disk. Check the method of putting bitcoin packets to D disk
(3) if your client displays English and you are not good at English, You can set it to Chinese. Click here to see how to set the bitcoin client to Chinese.
(4) the client's synchronization of network data will not affect our mining. First, we get our account address and click the "collection address" button of the client. At this time, you will see a very long list of addresses, similar to your bitcoin account, The bitcoin account address is automatically generated and unique in the world
(5) your account is now 0.00 BTC, which means you don't have bitcoin yet, but you can start mining now. Download an easy-to-use mining software cgminer. Click here to download the bitcoin mining software cgminer (cgminer can dig bitcoin and most of the coins, But not all currency mining can use cgminer)
(6) you need to confirm your graphics card model, if it is NVIDIA graphics card, then you can directly mine, please skip this step. If it is an ATI graphics card, you need to install an AMD SDK package in addition to cgminer. Click here to download the AMD SDK installation package
(7) cgminer is an English interface, but it does not affect a rookie to use it. Please unzip the downloaded cgminer to anywhere on your computer, and then enter the cgminer folder
(8) in the cgminer folder, create a new text file (txt) and write the content code as:
cgminer - O http://pool.btc38.com : 9332 - U XXXXXX - P btc38
change the above XXXXXX to the account address of your BTC wallet (get your address according to section 4 of this tutorial), After filling in, it is shown in the figure:
Xiaobian has configured the mine pool and port for you in the above code (the mine pool is a completely free mine pool provided by bitage). If you want to use other mine pools and ports in the future, please modify the mine pool URL and port by yourself
(9) change the. TXT suffix of the newly created TXT text file to. Bat suffix (if you compare dishes, the suffix will not be displayed at the back of the text file and the file name suffix will not be changed, please click here). After modification, the file is as shown in the figure:
(10) then double-click the run.bat file above to start mining. For example, if you get 0.001 bitcoin, it will be stored in the BTC address you fill in. (because BTC mining is very difficult at this stage, you may have to wait for a whole day to get BTC revenue. When mining, there may be some cards on the computer screen, because most of the resources of the graphics card are occupied.). (11) you may also want to know how to understand the mining interface. The figure below mainly indicates your speed and status:
note: in fact, the number of users of bitcoin mining is very large, and the output of bitcoin every 10 minutes is very limited, so mining is very difficult, If you have a powerful graphics card, there will be certain benefits. If your graphics card is not good, it may take you n hours to get a little bit of bitcoin. This tutorial is written by Xiaotian, editor of bitage (btc38. Com). The purpose is to let you get started and experience bitcoin. If you want to get better benefits through mining, You need to learn more about bitcoin pools and bitcoin mining strategies
4. Bitcoin mining pool
as mentioned above, the number of users of bitcoin mining is very large, and the output of bitcoin every 10 minutes is very limited, resulting in the situation that tens of millions of people scramble for a block. Therefore, if you use personal computers to mine alone, you may not be able to grab a block in a whole year, People have come up with a team mining method. The so-called team mining is the mining pool that we are going to talk about now
the mine pool is a server designed through a specific algorithm. All users connected to the mine pool server will form a team to mine. Although the performance of personal computers is small, the overall performance of thousands of people will become very powerful. In this case, the success rate of mining will be greatly improved, Once the team in the mine successfully creates a block, then all the team members will pay dividends according to the performance of each person's computer. For example, 1000 people are mining in the same mine pool. After digging out a block, the reward of n bitcoins generated by the block will be distributed according to the computer performance of the 1000 people. If your computer performance is strong, it may get 1 in 100; if the performance is backward, it may get 1 in 10000
in this case, the developer of the mine pool will generally charge 1% ~ 3% of the fee for each user as a handling fee, but because this method makes it more stable for everyone to get bitcoin, almost everyone will choose to mine in the mine pool instead of mining alone
as mentioned in the mining tutorial above, the mine pool provided free of charge in the bit age adopts the P2P technology architecture and does not charge any fees to users. It is one of the mainstream mine pools. In addition, there are BTC guild and deepbit, which are also very popular. Although the design of each mine pool is not the same, but the use method is basically the same and simple, so this tutorial will not do further description, you can explore by yourself. Even though Xiaobian has configured the mine pool and port provided by bit era for you by default in the previous tutorial, in order to let you have a deeper understanding of the mine pool, here are several mainstream mine pools for you to choose:
bit mine pool (free, recommended by Xiaobian) | bitcoin.cz (suitable for novices) | BTC Guide (the oldest brand) | deepbit (stable and efficient) | f2pool (domestic)
there are some points for attention in account setting. It is suggested to set a common account in e-mail
then there is the most important miner account setting. Miner obviously refers to CPU or GPU. You need to set an account for each CPU or GPU. Suppose you have two hd7990, you need to set four different accounts for four GPUs
after the account registration, it's time to take the second step. Download the bitcoin miner. Here we recommend the small and easy-to-use guiminer, which can support CPU, oepncl, CUDA and other computing modes. Your CPU and graphics card can achieve maximum performance
guiminer, a bitcoin miner, still needs to make certain settings. After the interface is changed to Chinese, it will be very simple
if the setting is correct, click the "start mining" button, the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, and you can also monitor the state through gpu-z or graphics card driver
the computing power displayed by guiminer is only a theoretical value. To know the actual output of bitcoin, you need to log in to the mine pool website, btcguild, to monitor your account information
now let's assume that you have g up several bitcoins, which naturally exist in btcguild, a foreigner's website. They can't be traded or converted into paper money for the time being
the functions provided by bitcoin China trading platform are clear at a glance, and you can understand them as soon as you read them, so you don't need to introce them any more. After you register, you can study them slowly
click the "bitcoin recharge" function of bitcoin China trading platform, and the system will provide you with a one-time bitcoin digital wallet address. This address can only be recharged once (for security reasons of the platform). After successful recharge, it will be invalid, and then the system will provide you with another address. Remember to update the wallet address in time every time, Otherwise, it will lead to recharge failure or loss
OK, now we import bitcoin from foreign websites into bitcoin China website, and it's up to you to deal with it. Keep it for appreciation, listing and selling, and exchange it for RMB. Specific how to operate, this Chinese website is easy to operate, we slowly study it
finally, let's talk about the equipment used in the bitcoin mining test. At first, I thought it was just an ordinary hd7870, but its computing power was much better than that of the ordinary hd7870. The key is that guiminer recognized it as the Tahiti core, which is the only core of hd7900 series. Looking at gpu-z, the card originally had as many as 1536 stream processors, Generally, the hd7870 of Pitcairn core has only 1280 stream processors. No wonder Dylan's graphics card has super computing power
for friends who hang up for a long time, performance is not the most important, and stability is the most important.
what needs to be explained:
after the handle version, you can only use the handle control, you can no longer use the finger touch screen control, and the convenience is reced.
9100f of U0 core needs shielding pin,
there are two sets sold on the Internet,
which can support a 16g DDR4
press the power button to switch on and off repeatedly, and try to put it on for a while. If you really can't, you can't just re install the system. If you can't re install it yourself, you can spend 30 yuan to find someone to help you
as long as your computer doesn't get stuck, has a blue screen, and is shut down suddenly, it won't turn on like this
please ask me if you have any questions.
By using secure encryption technology to store digital currency, you only need to have a contract address to transfer the currency. The function of this wallet allows you to put the currency in your wallet when you don't use it, which is higher than the security factor in the exchange
wallet is actually used as an address protocol, because all transactions on the blockchain are recorded in the whole network. Every bitcoin transaction to an address is recorded in the whole network and cannot be tampered with. When bitcoin arrives in your wallet, everyone can see the record to prove it
unlike most traditional currencies, bitcoin is a digital currency. Therefore, the method of this kind of currency is completely different, especially when it is obtained and stored. Because bitcoin doesn't have any physical shape or form, it can't be stored anywhere technically. Instead, it is the private key used to access your public bitcoin address and sign transactions that need to be stored securely. The combination of the recipient's public key and private key makes bitcoin transaction possible
there are several different forms of bitcoin wallets, which can meet different needs, and are different in security, convenience, accessibility and so on
paper wallet
a paper wallet is essentially a document that contains a public address and a private key that can be used to receive bitcoin, allowing you to spend or transfer bitcoin stored at that address. These are usually printed in the form of QR codes so that you can quickly scan them and add the key to your software wallet for transactions
paper wallets can be generated using services such as bitaddress or bitcoinpaperwallet, allowing users to create completely random bitcoin addresses and private keys. The generated document can then be printed, some of which offer tamper proof design, and even can choose to order holographic tags and use them
the main advantage of banknote wallet is that the key will not be stored in any place in digital form, which makes it completely free from hacker attacks. It can record the malware users hit and basically any form of digital theft. However, some precautions still need to be taken when creating wallets
obviously, before generating a paper wallet, you need to make sure that no one is watching you. To eliminate the risk of any spyware monitoring activity, it is recommended to use a clean operating system running from a USB flash drive or DVD, such as Ubuntu
in addition, once the paper wallet is set up, the website code should be able to run offline, which allows you to disconnect from the Internet before actually generating the key. Finally, use a printer that is not connected to the network
in addition, it is very important to know that you are printing valuable personal information on a piece of paper. Therefore, you need to take some measures to protect that piece of paper. For example, it is suggested to put it in a sealed plastic bag to prevent water stop, moisture and general wear. Some people like to laminate it and store it in a safe, storage box or entrust a lawyer to handle it
physical bitcoin
physical bitcoin usually preloads a fixed number of BTCs, and the intention is that as long as the private key remains hidden, it cannot cost its value. This is usually achieved by implementing tamper proof seals
bitbill's first proct was like a credit card, but most of its subsequent substitutes were shaped into a round medal. Mike Cadwell, a cryptocurrency enthusiast nicknamed "casascius", created the first popular casascius physical bitcoin in 2011
the private key is hidden under the strippable hologram, and when it is removed, it leaves the tamper proof mode. In exchange, the coin lost its numerical value. Since then, there have been several new coin makers
physical bitcoin is a very convenient way to store your funds more safely, which is very useful in offline transactions. Most importantly, they have recently become a valuable collection. However, the main drawback is serious security issues
in November 2013, Mike Cadwell was asked to stop the operation of the financial crime enforcement network because his work was considered to be a money sender. The rules of the campaign were so overwhelming that he had to stop selling items containing digital bitcoin. Since BTC is still a legal gray area in many countries, these items may even be considered counterfeit by the authorities
mobile
BTC is an indispensable tool for those who actively use bitcoin every day to pay for goods or trade face-to-face in stores. It runs as a smartphone app, stores your private key and allows you to pay for things directly from your phone
in addition, some applications enable users to use their smartphone's near-field communication function, which means that they can simply click on their phone to oppose readers without having to provide any information at all
any complete bitcoin client needs to access the whole blockchain ledger, which is growing and needs several thousand megabytes of storage space. Therefore, mobile wallet uses simplified payment verification (SPV) technology. They only apply to a very small subset of the blockchain and rely on trusted nodes in the bitcoin network to ensure that they have the correct information
although bitcoin storage is a convenient mobile solution, mobile wallet is vulnerable to hackers. In addition, if someone just accesses your mobile device, you may lose control of the wallet. There are a variety of bitcoin wallet applications running on Android devices. Apple banned bitcoin wallets from the app store in February 2014, but withdrew its decision a few months later
Web wallet
Web wallet stores your private key on the server of the company providing such service. The server is always online and controlled by someone else. Different services provide different functions, some of which connect to mobile and desktop wallets to your address on the device you own
very similar to mobile wallet, e-wallet enables users to access their funds anytime, anywhere through any device connected to the Internet. But unless implemented properly, the organization that runs the site may access your private key and take full control of your money. In addition, some e-wallets operate on the basis of exchanges, and some exchanges close down and escape users' funds
Desktop wallet
Desktop wallet has been downloaded and installed on your computer, and your private key is stored on the hard disk. By definition, they are more secure than online and mobile wallets because they do not rely on third parties for data and are more difficult to steal. They are still connected to the Internet, which makes them inherently insecure. But desktop wallets are a great solution for those who trade a small amount of bitcoin from their computers
Desktop wallet has many different choices to meet different needs. Some focus on security, some focus on anonymity, etc
Hardware
Hardware wallet is a unique bitcoin wallet, which can store the user's private key in a secure hardware device. This is the safest way to store any amount of bitcoin, and there is no verifiable event that money is stolen from the hardware wallet
unlike paper wallets, paper wallets must import software at some time, and hardware wallets can be used safely and interactively. In addition, they are not affected by computer viruses, and the stored funds cannot be transmitted to output devices in clear text. In most cases, their software is open source
some hardware wallets even have screens, which adds another layer of security because they can be used to verify and display important wallet details. For example, the screen can be used to generate recovery phrases and confirm the amount and address of the payment you want to make. Therefore, as long as you invest in a real equipment with good reputation made by a reliable and competent manufacturer, your funds will be safe and reliable
bitcoin wallet and security
possible problems:
capture malware. Malware can scan your disk and find your private key. In a few seconds, all your bitcoins will disappear. Trojan can encrypt all the files on the hard disk. After that, it may find all the links to your wallet, realize how much money you have and ask for the exact amount of bitcoin to decrypt your hard drive
virtual exchange can use your money to escape. You can lose the laptop or mobile phone on which the wallet is installed
suggestions:
< UL >avoid using any wallet that needs Internet connection; Please use the refrigerated option instead
check everything carefully. For example, you can receive an email from blockwallet, but it's actually from blockcwallet, and if you authorize, your bitcoin will disappear immediately
the reason why the website can't enter may be e to the problems of the website itself, the Chinese government's blocking the website, or your network speed. At present, the website can be accessed normally.
let's think about it, Pei Yurong is the chief salesman of the old biography. Now he is wanted by Changde police in Hunan Province and has been hiding in the United States. It's impossible for him to come back. Yan Bo is the same. The Pacific Network he used to do was the biggest one in the history of China. Meikuang was also led by him. These companies had accidents, but he was on the run all the time. Pei Lei, the so-called chairman of "EGD", was just packaged by them. The way they packaged Hou Peng was the same as meikuang. At the beginning, they publicized Hou Peng, saying that Hou was always the president of American business association, Now Pei Lei is packaged as a brilliant young man, making hundreds of millions in the field of virtual currency. In fact, Pei Lei is their puppet, and the so-called "EGD" is not worth a cent at all. It's entirely their own business. It's not a real digital currency at all. There's no open source, no decentralization, it's just a number on their own server. They can change it as they want, Their website did not mention any technical information, let alone open source! What's more, virtual currencies are basically deceptive. Bitcoin is becoming less and less valuable and has been falling. At present, there are hundreds of virtual currencies in the world, which are worthless. By packaging "EGD" into a currency that can earn hundreds of times, they cheat ignorant investors again. Moreover, all the overseas companies and teams mentioned by "EGD" are packaged. Now it's very easy to pay a few foreigners. All the servers of "EGD" are in Hong Kong through search, It's not in the UK as they said. Although they will point to the UK, the real address is Hong Kong New World Telecom, and all the traffic of the website is in China
except for the cheated in China, no one else in the world is visiting this website
they have always claimed that edgcoin was issued to more than 20 countries in the world on January 1 this year:
in fact, their domain names were registered only in April this year, and they claimed that they were global British companies. As a result, when they registered their so-called money bags, they still needed email authentication, but the email that actually issued authentication was China's 126 email, What a joke! These ironclad evidences are enough to prove that "EGD" is a company they once again packaged to cheat everyone. It is said that Pei Lei, chairman of "EGD" has been hiding overseas
Friends of meikuang, don't be fooled. Do we dare to participate in some companies which are the most wanted criminals? If we don't work hard, the money we invested in before will be hopeless. The money they invested in "EGD" future city now is the money we invested in meikuang at that time. Now they claim to collect tens of millions every day, and they don't save the company even if they have so much money. They have been fooling everyone. We must join hands to report them. Only by seizing them can we hope for our money. When they run away again, it will be over.
