1. After the ZF policy, the domestic bitcoin exchanges were basically closed on October 31. Therefore, if bitcoin wants to be realized, it can only be traded on the OTC exchanges of bitcoin abroad. Many of these closed platforms have opened OTC exchanges abroad, but I don't use much. I only use the coinbee platform and sell a few coins. This is how his OTC trades, The basic routines are the same. First you have to register your account, then get your wallet address from the coinbee platform, then recharge the bitcoin into it, choose to publish advertisements, choose the quantity, price, acceptable transfer method, such as Alipay or bank transfer, if someone wants to buy your currency, he will Send a transaction request to you. Then you trust bitcoin, wait for him to call you, and click on the platform to complete the payment. After you confirm that you have received the payment, you can click release bitcoin on the platform to complete the transaction. This is my actual operation. There will be risks. Be careful. This is my personal practice, and I hope it will be useful to the subject.
2. In order to understand the technical principle of bitcoin, we need to understand two important cryptographic techniques: hash code: it converts a long string into a fixed length string, and its conversion is irreversible, that is, it is impossible to guess the original string from hash code. Sha256 is mainly used in bitcoin protocol
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. How do I pay? When I pay from address a to address B of the other party, the payment amount is e. at this time, both parties will announce the transaction information to each network node, telling address a to pay to address B, and the payment amount is e. In order to prevent the third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. at this time, the network node receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU intensive. How to let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people.

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband
extended data
users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes
4. The operation of bitcoin is simple. It's not as difficult as you think, and it's not as magical as the propaganda. The future of bitcoin should be simpler, faster and more convenient
in fact, you don't need to understand some principles of bitcoin, because it's very difficult to understand. Even professionals may not understand all of them. As long as you can use it
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system
you can get it through bitcoin mining or direct purchase on the trading platform
bitcoin mining is the process of using your hardware to calculate mathematical problems, confirm transactions, and ensure the whole network system. As a reward, you can get a certain bitcoin reward. At present, mining is competing for energy consumption and electricity price, and mining income is close to cost price. Avalon's fourth generation chips have certain advantages in energy consumption
you can buy bitcoin directly by recharging the legal currency to the trading platform, and the third-party guaranteed transaction.

Wang Fuzhong, a postdoctoral fellow of Peking University and a famous economist, said in the column "happiness is coming" that farmers should be eliminated, which triggered a network curse war in the 5000 year history of Chinese culture, farmers have always played a very important role, and they are also the parents of growing food. During the Anti Japanese War, Comrade Mao Zedong said that in order to win the war, we must first take the people as the basis and accept the people's will. It can be seen that the people are very important, and it is difficult to complete the task without the support of the people
the name of the man who said that he would "wipe out" the farmers is Wang Fuzhong, which is unbelievable. The man who said this is actually a professor of Peking University. Wang Fuzhong also said that "the farmers have little to do with the food we eat, and they almost have no contribution." today's children all know that the food is the hard work of the farmer's uncle, As a professor of Peking University, he even said such words, which makes people feel angry. How about the current situation of Wang Fuzhong? Let's get to know
Wang Fuzhong published the theory of "farmers are useless", then denied the medical skills of traditional Chinese medicine, and cursed "Tiangong No.1" . After the incident, Wang Fuzhong was expelled by Beihang. Then, because the incident of "insulting" the farmers continued to ferment, I don't know whether Wang Fuzhong really knew he had done wrong, or under the pressure of public opinion, he apologized to the farmers< now a few years have passed, and Wang Fuzhong is also aware of his mistakes. Now he dare not make any comments at will. He is an economist and publishes some books in a low-key way
in fact, every job in the world is equal, and there is no distinction between high and low. Even if you are a university professor and the other party is a farmer, it is important to respect others and their work. Everyone is equal
6. There is also the problem of pyramid selling, so we should not be careful about the location
7. Mining machines are used to dig. There are many in the market. However, bitcoin mining still requires high computer configuration. This is not the key point. The key point is to find a reliable platform for trading. Otherwise, it is also a waste of time and money. I have been working on this platform for a long time, and the benefits are good and stable, Reputation has been good http://tieba..com/safecheck/index?url=x+Z5mMbGPAsY/M/Q/ +0F9cuoglZ0mWgPSsR2lbVfu3pr+xI3k4IPor+8Mx4Aubb13aBkT/9itqayQJ2Pah4egTNMg==
8. Buy bitcoin
if you have the experience of buying and selling stocks, it's easier to buy and sell bitcoin. In order to better understand the new people, I will take selling and buying stocks as an example to talk about the trading of bitcoin
if you want to buy stocks, the first thing you need to do is to open an account in the stock exchange company, and then bind the bank card for trading. Nowadays, many young people will choose to open an account online, and then directly buy the stocks they value through the Internet. This approach is closer to bitcoin trading
buy bitcoin by buying stocks: first of all, you need to register your account number (fire coin, cloud coin, etc.) in the relevant bitcoin exchange, and your account number needs to be registered by email. After the account number is registered, enter the exchange to fill in the relevant information and bind the bank card, and then transfer the funds to the exchange through online banking transfer. Finally, you can buy bitcoin
transfer note here needs to be noted: the exchange does not accept Alipay, WeChat and other transfer methods. It's usually through online banking. So we must pay attention to this
after the above operation, you can get the first bitcoin in your life. Since China banned all domestic bitcoin related exchanges in September this year, it has become somewhat difficult for RMB to buy bitcoin
therefore, bitcoin cannot be purchased by the above methods in China
the current method of purchasing bitcoin
e to the prohibition of domestic exchanges, the purchase of RMB becomes more and more difficult. Of course, if you've been trading all your money before, you can just exchange bitcoin directly. If you don't have money on the exchange, you need to buy bitcoin over the counter< Over the counter trading (OTC): you can understand it as a trading mode like Taobao, which is not too much
after the seller registers his commodity (bitcoin) in the corresponding OTC exchange, the buyer who is interested in the commodity will contact. Then the buyer transfers the amount needed to purchase the goods through WeChat or Alipay to the seller. After receiving the money, the seller will transfer the corresponding bitcoin to the buyer. The platform plays a confirmation role in the whole transaction. To some extent, you can understand it as the role of platforms such as Taobao or Jingdong
after you receive bitcoin, you can transfer the bitcoin on the OTC exchange to your previously registered exchange account through the bitcoin address. At present, the commonly used transactions are all coin an, bitfinex, etc. You can also convert your bitcoin into other currencies in these exchanges, such as eth, EOS, BCH, OMG, etc
in this way, the whole process of RMB purchasing bitcoin is successfully completed.
