1. First of all, we need to find a mine pool which is easy to operate and proces stable output. The function of the mine pool is to subdivide the data packets for each terminal. We can pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through a precise algorithm
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.
2. Bitcoin wallets are not very useful. You can download an okex with various wallets in it.

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








  • 4. Bitcoin is a virtual currency, the world's general cryptocurrency. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. But it's going to close soon. Bitcoin is a decentralized and open source digital currency, which will eventually reach a fixed unit of quantity: 21 million, which will not be reached before 2140. The current rate of money proction is 25 new bitcoins per 10 minutes, and the number will slowly decline. It will be halved in 2017, and then it will be halved every four years until it reaches the upper limit. Now who are the people who get those bitcoins that are proced every 10 minutes? It's a technical process, which is essentially to solve difficult mathematical problems, and hard systematic work will be rewarded. In short, mining is a process of running a program, which helps to verify transactions on the network. Unlike other transactions, it is completed by solving difficult mathematical problems. This special process also leads to its becoming a kind of free currency. Every few minutes, a new bitcoin finds a miner, so that they can protect themselves. Now mining is becoming more and more difficult. Under the leverage of market economy principle, their prices will be higher and higher. If the utilization rate is higher and higher, the prices will be higher. Using bitcoin, you can buy goods and services, convert them into real currency at any time according to the bitcoin exchange rate at that time, and sell bitcoin to other users. If you want to join the mining team, the early hardware and power costs are inevitable, so you can try various hardware settings and calculate its mining efficiency. Risk the price fluctuation of bitcoin is its biggest risk, because the whole market value has reached 1 billion US dollars, many people are eyeing this market. Last month, the value of a bitcoin rose from $30 to a peak of $75; But in 2011, the exchange rate of US dollar to bitcoin fell from US $33 to US $2.51, and it took a long time to recover. Now its transaction value is 125 dollars, so it is very valuable. Instawallet was closed as a bitcoin hosted wallet on Thursday because of the attack, and it indicates that 90 days later, if no one else claims to have received the same URL, users under 50 bitcoins will recover 50 bitcoins. For indivials, if you pay attention to privacy, want to trade a small amount of money without government regulation, and have a wallet that can be entrusted with the custody of bitcoin, you can have a try. There is still a long way to go before it can replace the existing currency. The infrastructure under it needs to be well constructed to be generally accepted. If you want to buy one or two in the near future, it is absolutely no problem.
    5. The development is OK. I think it is more stable than other platforms.
    6. Insert your trezor hardware wallet into the computer, click the coin, the address, and send your bitcoin to the address generated by
    trezor.
