In fact, Bitcoin also has applications in real life. For example, during the Lushan earthquake in Sichuan, China first allowed Bitcoin to be used as a donation. In fact, bitcoin only became popular at that time. Everyone is curious about what Bitcoin is and begins to understand it.

How do we get bitcoin? In fact, we all know that there are two ways:
One way is to go to the online market and buy it in RMB according to the conversion. Now, it's almost the same. A bitcoin costs more than 5000 yuan.
Another method is to obtain bitcoin by downloading a certain number of mathematical problems from the client.
In fact, the second method is not so easy to obtain, but also requires a lot of cost to earn. A friend of mine can hardly earn 0.00 16 bitcoin after running for a few days, which may be related to the method and computer.
4/6
Nowadays, many people use bitcoin to invest. In fact, investing in this thing is still risky. The country has not recognized the legality of this thing. Nowadays, it is only traded online to a large extent, and some people use it for black market transactions. Bitcoin will definitely appreciate in the near future, but it depends on how the government regulates the network in the next step, because the network supervision is very backward now, and many problems appearing on the Internet have not been solved in reality. Perhaps the government is also worried about this problem now.
5/6
Imagine that there is no unified currency in operation in the world at present, and it is also in the form of exchange. It would be a good thing if Bitcoin could undertake this heavy responsibility. Now, through virtual form, Bitcoin can buy everything in real life. Although the government does not admit it, it already exists very realistically. However, many people think that Bitcoin is a conspiracy to use the energy or financial resources of future generations to do things for predecessors. In other words, now that we are so keen on Bitcoin, the money has long been earned by the earliest people.

The difference between bitcoin and QQ coins;
Bitcoin does not belong to any country, company or group. It exists widely in the network and can be exchanged with the currency of any country at present. Now all countries attach great importance to it, although it has not yet become legal tender.
QQ coin belongs to Tencent, and now Tencent is vigorously promoting this QQ coin. Other institutions or companies rarely promote this thing because it will not bring any benefits to it.
However, in recent weeks, the value of this currency has been rising all the way until 10 reached the peak of $266 in April, and then the value of this currency plummeted to 105, a decrease of 6 1%. What is Bitcoin? What is the value of Bitcoin? Many people are talking about this virtual currency. Opinions are divided into two groups: one group thinks that Bitcoin seems to be a Ponzi scheme; Another school thinks that Bitcoin is an innovation.
But there is still a group of people who don't know anything about Bitcoin-and this group of people may be the vast majority.
Next, we borrow an article from Business Insider, a technology blog site, to give you an entry-level popularization: What is this crazy currency? What is the difference between it and real money?
(1) What is Bitcoin?
Bitcoin, which appeared in 2008, is a decentralized and anonymous currency that can only be used in the digital world. It does not belong to any country or financial institution and is not subject to geographical restrictions. It can be exchanged anywhere in the world.
(2) The origin of Bitcoin
In 2008, someone published a paper under the pseudonym of "Satoshi Nakamoto", which described the usage of Bitcoin. 1 year later, the first transaction of Bitcoin was completed.
(Tiger Sniffing Note: According to this article in Forbes Chinese website, this mysterious figure with a Japanese name has disappeared from the Internet. No one knows whether he is really Japanese or a huge organization. Wired speculates from his wording that he may have been born in the United States, or even be the code name of a mysterious group of Google or the National Security Agency. )
(3) Where did Bitcoin come from?
Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to algorithms to "mine" bitcoin. When users "mine" bitcoin, they need to search for 64-digit numbers with computers, and then compete with other gold diggers through anti-complex puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, they will get 25 bitcoins.
Because the Bitcoin system adopts decentralized programming, at present, only 25 bitcoins can be obtained every 10 minute, and by 2 140, the upper limit of bitcoins in circulation will reach 210 million. In other words, the bitcoin system can be self-sufficient, coded to fight inflation and prevent others from destroying these codes.
(4) How much is Bitcoin worth?
When it first appeared, bitcoin was almost worthless, and 1 dollar could buy 1309.03 bitcoins on average, but now 1 bitcoin is worth 135.3 dollars. Interested friends can visit the Preev website to learn about the real-time quotation of Bitcoin.
(5) Can Bitcoin be exchanged for cash?
The answer is yes. You only need to get in touch with the bitcoin exchange agency to complete the exchange. Mt. Gox is the most popular bitcoin exchange platform at present, but now the platform only accepts new members through one application. In addition, there are several large exchanges that can exchange and trade Bitcoin.
(6) Why should Bitcoin be anonymous? How to achieve anonymity?
Bitcoin is anonymous because it is based on a decentralized system. Bitcoin exists completely independently, and the outside world cannot shut it down through some core infrastructure.
Anonymity is very useful for those who don't want to associate their names with the goods or services they buy. What outsiders see is nothing more than your bitcoin wallet address and a string of random words and numbers, and there is no other information that can identify individuals. At the same time, for relatively paranoid users, you can also create multiple new wallets for free.
(7) What can Bitcoin do?
Earlier, it was reported that criminals used anonymous bitcoin to buy illegal goods such as drugs and guns, but in fact, many legitimate businesses now accept bitcoin transactions. For example, Howard Johnson is willing to accept bitcoin payment, while Bite Electronics is a consumer electronics store that only accepts bitcoin.
(9) Is Bitcoin legal?
Bitcoin is not a real currency. It doesn't represent a certain value like paper money and coins. At present, the US government is not worried about the possible impact of Bitcoin on the financial market, because it can only be controlled by enacting corresponding bills. Compared with the "free dollar" that once appeared, the latter was a currency that could replace the real thing from 1998 to 2009, and its creator Bernard von NotHaus was also convicted of making, owning and selling money by himself in 201/kloc-0.
At present, information about Bitcoin can be obtained through various channels, and Bitcoin subreddit and Bitcoin magazine are both sources of information for obtaining Bitcoin. From the tiger sniffing network
1. Relatively concentrated capital
Global capital is concentrated in the system of government agencies and single financial institutions, which brings a series of uneven distribution. Unfair asset holding, unfair distribution and a series of riots derived from it are constantly impacting this centralized system. In order to resist this centralized government system, non-governmental organizations are constantly looking for new ways of fund management. This antagonistic behavior, which appeared out of distrust of the central system, finally promoted the start of the trust machine.
2. Blockchain prototype
Until 2008, a scholar with the pen name "Satoshi Nakamoto" published an article entitled "Blockchain: A Peer-to-Peer Electronic Cash System", hence the name of blockchain. In June 5438+the following year 10, a series of program codes appeared, and the programming technology has not been cracked so far. This code provides a prototype for the emergence of blockchain teaching. Therefore, Satoshi Nakamoto created the Bitcoin Creation Section and produced the first batch of 50 Bitcoin awards. The emergence of blockchain also indicates the emergence of trust mechanism, which no longer depends on centralized system to complete the creation and ownership of blocks. The connotation of blockchain is not only bitcoin or some kind of digital currency, but also a series of trust-based applications such as smart contracts.
Create equality
Therefore, blockchain and bitcoin can be said to be a group of Internet products that do not trust centralized institutions and the existing financial system and use advanced technology to counter the current global monetary system. The birth of blockchain promotes the traditional capital holding market and produces fair, just and equal holding rights, so it is favored by foreign anarchists and widely circulated abroad.
4. Core concept
The core idea of a single blockchain is to ensure that the value of something is not credible through a centralized system. In the blockchain system, each node only needs to act according to its own interests to ensure the security of the system.
On June 4th, 2009, Beijing time, Satoshi Nakamoto, the author of the white paper, personally created the first bitcoin creation block on a small server in Helsinki, Finland, and won the first prize of 50 bitcoins, thus the first bitcoin came out.
About bitcoin
20 10 on may 22nd, an early bitcoin enthusiast, Laszlo, an American programmer, wanted to exchange bitcoin for something. He posted on a bitcoin forum that he hoped to exchange 10000 bitcoins for two pizzas worth $25. A British volunteer made a deal with Laszlo and got 10000 bitcoin. This is the first time that bitcoin has a price, which has caused a great sensation in the entire encryption industry. To commemorate this transaction, people call May 22nd every year "Bitcoin Pizza Day", and bitcoin lovers get together to eat pizza to celebrate. Based on the current bitcoin price of Bitcoin, the two pizzas at that time were worth about 300 million RMB, and Laszlo, the brother who bought the pizza, cried and fainted in the toilet.
6 data blocks can be generated globally every hour, and 265,438+0,000 data blocks can be generated every 4 years; Then, the reward of the data block is paid in a decreasing way. Pay 50 bitcoins for each data block in the first four years, 25 bitcoins for each data block in the next four years, 12.5 bitcoins for each data block in the third and fourth years, and so on ... Finally, the total number of bitcoins is-265,438+00,000x (50+25+65,438+00 brackets. By 2040, the total number of bitcoins will reach 2 1 billion.
First of all, the bitcoin virus has once again made it the focus. On May 12, the global sudden bitcoin virus attacked public and commercial systems crazily!
More than 40 hospitals in Britain were attacked by large-scale cyber hackers, and the National Health Service (NHS) was in chaos.
Campus networks of many universities in China have also collectively fallen.
Nearly 74 countries around the world, such as Britain, Spain, Italy, Portugal, Russia and Ukraine, were severely attacked.
After being infected, ransomware usually encrypts all documents, emails, databases, source codes, pictures, compressed files and other files on the user's system in some form, making them unusable, or interferes with the normal use of the system by modifying the system configuration file, thus reducing the usability of the system;
When a user opens a document in a hurry, the ransomware will send a blackmail notice to the user through a pop-up, a dialog box or the generation of a text file, asking the user to remit money to a designated account (pay a bitcoin ransom) to obtain a password to decrypt the file, or to obtain a method to restore the normal operation of the system.
Second, talk about the origin of Bitcoin. The concept of Bitcoin was first put forward by Satoshi Nakamoto in his paper Bitcoin: A Peer-to-Peer Electronic Cash System (Chinese Version) in 2008. In 2009, according to Satoshi Nakamoto's idea, we designed and published open source software, and established a P2P network on this basis.
It is a 2 1 10,000 digital currency, which has the same characteristics as the Internet, such as decentralization, globalization and anonymity. Moving Bitcoin to the other side of the world is as simple as sending an email, with low cost and no restrictions.
Bitcoin is therefore used in cross-border trade, payment, remittance and other fields.
Bitcoin is a P2P digital currency. Point-to-point transmission means a decentralized payment system.
Unlike most currencies, Bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations according to a specific algorithm. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transaction behaviors, and uses cryptography to ensure the security of all aspects of currency circulation.
The decentralized nature of P2P and the algorithm itself can ensure that the currency can not be manipulated artificially and create a large number of bitcoins.
The design based on cryptography can make bitcoin only transferred or paid by the real owner. This also ensures the anonymity of currency ownership and circulation transactions.
The biggest difference between Bitcoin and other virtual currencies is that its total amount is very limited and extremely scarce.
The monetary system once did not exceed1050,000 for four years, and the total will be permanently limited to 21050,000.
From the essence of Bitcoin, the essence of Bitcoin is actually a special solution generated by a bunch of complex algorithms. Special solution refers to a set of infinite (in fact, bitcoin is limited) solutions that can be obtained through an equation group. And each special solution can solve the equation, which is unique. Take RMB as an example. Bitcoin is the serial number of RMB. If you know the serial number on a bill, you have this bill. The process of mining is to constantly seek the special solution of this equation group through huge calculation. This set of equations is designed to have only 2 1 million special solutions, so the upper limit of bitcoin is 2 1 million.
Bitcoin is so popular because it has the characteristics of currency and can be accepted, traded and stored all over the world. Formed its unique living environment.
Second, Bitcoin is digital gold. Due to its broad prospects and huge imagination, the price of Bitcoin has continued to rise since its birth in 2009. At 20 1 1, the currency price reached 1 USD, and at 20 1200 USD, which exceeded the price of 1 ounce of gold.
Bitcoin can be cashed and converted into the currencies of most countries.
Users can use Bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use Bitcoin to buy real-life items.
After the birth of Bitcoin, as an unprecedented new currency, it has experienced numerous market tests and technical attacks and has always stood firm.
Now Bitcoin has grown into a currency system with millions of users and tens of thousands of merchants accepting payments and a market value of tens of billions of dollars.
On February 26th, 20 14, Senator Joe Manchin, Democrat of West Virginia, sent an open letter to several regulatory departments of the US federal government, hoping that the relevant departments could pay attention to the current situation that Bitcoin encourages illegal activities and disrupts the financial order, and demanded that action be taken as soon as possible to completely ban the electronic money.
Third, China's Bitcoin trading platform China also has three platforms for trading Bitcoin, namely Huobi.com, Currency Bank and Bitcoin.
20 17 65438+ 10/01,China People's Bank Shanghai Headquarters, Shanghai Financial Office, etc. On-site inspection of btc China was conducted, focusing on whether the enterprise carried out credit, payment, remittance and other related businesses without permission or authorization; The implementation of the anti-money laundering system; Financial security risks, etc. 20 17 65438+ 10/2. The business management department of the central bank has also settled in trading platforms such as "Huobi". Com "and" Coin Bank "in Beijing.
1From 20 17 12: 00 on October 24th, the three major bitcoin platforms in China officially began to charge transaction fees.
At present, there are a large number of virtual currencies issued by fraudulent companies on the Internet, claiming to be imitators of Bitcoin, but in fact they are pyramid schemes or Ponzi schemes (such as rare coins, Vicat coins, Morgan coins, etc. ), or although it is not a pure scam, it is highly controlled by the dealer (such as shark coins and bran coins, etc.). ).
The biggest difference between these fraudulent coins and Bitcoin is that Bitcoin does not belong to anyone or organization, but is an uncontrolled and decentralized currency. These counterfeit coins have a clear issuer and are completely controlled by the issuer. Cheater coins are also called "coins", but they are completely different from bitcoin.
Unlike open-code bitcoin, most scammers don't open the code or have no code at all. It's just a number on the website, and the publisher can change it as he wants.
Cheater coins are often promoted by people who post hard, and generally use the means of pulling people up and down to absorb funds.
One of the simplest ways to judge is that if XX coins are issued by XX company, which is known as "powerful" and has a broad prospect, and the investment/mining income is guaranteed to be high, and you need to spend money to make money, then 100% is a fraudulent coin.
Try to say it in simple sentences, I hope you can understand.
In the past, you may have heard the word bitcoin more than 1000 times, but you still can't understand what bitcoin is.
In short, Bitcoin is an encrypted file that can be stored and transmitted easily. It is a cryptocurrency, and it is the first and largest cryptocurrency.
The current bitcoin price is about 50,000 yuan each (the highest130,000). You must ask, why pay a lot of real money for such a piece of code?
The story begins with barter. The first batch of bitcoin transactions were achieved through bargaining in the forum. For example, there was a transaction like this: two pizzas were bought with 10000 bitcoins.
The core of Bitcoin is a new form of digital assets, which is created through unparalleled encryption combination and peer-to-peer network. So how does it provide us with value?
If you want to send money abroad, whether by bank wire transfer or online service, you have to pay a certain bank service fee or transaction fee. In fact, funds are only transferred from one account to another, but why do you lose some money?
But bitcoin is different. It does not belong to any country, institution or individual, is not regulated, and can be obtained by anyone with Internet connection, and can be freely transferred to any place in the world with the click of a mouse.
Maybe you will ask, how to ensure its security, isn't this a scam? This has to mention a technical term: blockchain, which is the basic technology that Bitcoin relies on. You can think of it as a ledger, recording every transaction on the Internet. All people who surf the Internet can access it. When anyone initiates a new transaction (sending or receiving bitcoin), the transaction will be verified through the blockchain. Blockchain solves the trust problem between people to the greatest extent.
Bitcoin is similar to gold and can be considered as digital gold. The supply of bitcoin is limited (at most 2 1 10,000, currently exploited16.7 million), and the exploitation will become more and more difficult. It is precisely because of the limited supply that many people think this is a value reserve. Therefore, mining (adding bitcoin) and investing in bitcoin have become very hot topics in recent years.
Due to the growing influence of bitcoin, governments around the world have stepped in to supervise bitcoin transactions, making it a more mature part of the financial system. In China, financial institutions and payment institutions have been explicitly prohibited from conducting business related to bitcoin to avoid some illegal activities in bitcoin transactions.
Bitcoin is different from RMB, USD, GBP and other currencies. Bitcoin is a network virtual currency and a decentralized virtual currency, just like Q coins, but it is centralized, which means it is regulated. Unlike bitcoin, bitcoin is a decentralized virtual currency, which means it is not regulated by the center. It is generated by a large number of calculations according to a specific algorithm. Personally, I think this is a tool for harvesting wool in the United States. Nobody can touch it.
In 2008, Satoshi Nakamoto released the white paper Bitcoin: A Peer-to-Peer Electronic Cash System, which announced the birth of Bitcoin. First of all, please pay attention to the title core of the white paper "Peer-to-Peer" and "Electronic Cash".
1. What is "peer-to-peer"
Peer-to-peer means that the bitcoin system does not need a specific server. For example, when we log in to WeChat, we need to connect Tencent's WeChat server and Ali's Taobao server. But what if these centralized servers shut down? The answer is that we can't log on to WeChat or Taobao. Bitcoin's "peer-to-peer" network structure does not depend on a server or a group of servers. It can be understood that each participant in the Bitcoin system is both a user and a "server", so an institution or individual cannot control Bitcoin and cannot tamper with the transaction records of Bitcoin. So Bitcoin is a decentralized digital currency.
2. Electronic cash
As the name implies, Bitcoin has the ambition to replace the traditional currency since its birth, and it wants to become a real currency in the future. According to Satoshi Nakamoto's algorithm design, the total amount of Bitcoin is constant, totaling 2 1 million. The distribution of bitcoin does not depend on an institution, but is calculated and generated according to a specific algorithm, and the production process is also called "mining". At the same time, the "output" of Bitcoin is halved every four years, so Bitcoin will not face the phenomenon of currency overshoot. At present, one of the reasons for the high housing prices is the excessive currency. In 2008, the total M2 of broad money in China was only 47 trillion, but now it has reached 174 trillion in 20 17 years, and the total m2 of money has increased nearly three times, which is also the main reason why the real increase of house prices in the past 10 years exceeded three times on average.
Bitcoin is a kind of digital currency. The concept of Bitcoin was first put forward by Satoshi Nakamoto in 2009.
Bitcoin is not issued by a specific monetary institution, but is generated by a large number of calculations according to a specific algorithm. Bitcoin can't artificially manipulate the currency value by manufacturing a large number of bitcoins. Bitcoin can only be transferred or paid by the real owner. This also ensures the anonymity of currency ownership and circulation transactions. The total number of bitcoin is very limited. The monetary system once did not exceed 654.38+00.5 million for four years, and then the total will be permanently limited to 265.438+00 million, so there will be no inflation in Bitcoin.
20 10 on may 22nd, Laszlo Hanyecz, a programmer in Jacksonville, Florida, bought a pizza worth $25 with 10000 BTC. This is the first bitcoin transaction in the real world.
Due to the anonymity of bitcoin circulation transactions, it is widely used in the global dark network and is used to buy guns, drugs, murder and other criminal acts.
The value of bitcoin is mainly reflected in people's recognition of it. If one day people all over the world don't recognize Bitcoin, then Bitcoin will no longer have any value and will only become a string of codes.
A technology base on blockchain,
Derived virtual currency.
Because the amount is limited, the money generated every year is greatly reduced, so the value is high.
Coupled with commercial means such as speculation, bitcoin prices fluctuate!
Blockchain technology is simply decentralization.
Instead of taking the government and other organs as the center, everyone can be the center.
Maybe in the future, in a new way,
People trading, beyond the government and other relevant departments,
Blockchain technology is to provide such an environment!
Virtual currency like bitcoin,
There are already many.
Such as the Ethereum.
Generally speaking, it is a kind of virtual currency developed by different companies using blockchain technology and produced according to a certain invariant algorithm, and it is constantly produced, but the number is slowly decreasing until it is infinitely small.
Now some domestic enterprises. Games based on blockchain technology are also being launched.
Lai Ci dog. Wait a minute.
It is a way to generate your own virtual currency.
By making Lai Ci dogs do so-called jobs and so on.
In order to generate virtual currency, algorithmic calculation is performed,
And the number will be less and less. That's why there will be appreciation.
It's just that the value of domestic virtual currency is not so high at present, and it needs to rise slowly.
Interested people can register to play.
Of course, blockchain technology will provide a safe environment.
Because it will collect your information. This is an unchangeable fact.
Therefore, people will absolutely trust the emergence of blockchain technology, thus providing you with an unprecedented environment!
With the skyrocketing of Bitcoin, Bitcoin has once again become a hot topic, and stories and jokes about this magical currency have been excavated again.
Immediately, the local tyrants came out to pull hatred: "I bought 4,000 bitcoins for 300,000 yuan a few years ago and got them back last week. Is it really tomorrow or an accident, which comes first? "
Of course, some people are frustrated when they are proud. Recently, there was a Weibo, saying that an old buddy and one of his classmates bought 20,000 bitcoins for a few cents a few years ago. At that time, they designed a complicated password to prevent the other party from buying and selling separately, and each of them recorded half. Only when they enter the password together can they log in. As a result, his classmate died in a car accident while traveling abroad last year. Today, Bitcoin rose to $65,438+09,340 each. He started his business again in half a century.
So, what exactly is Bitcoin? Bitcoin is essentially a special solution generated by a bunch of complex algorithms. Special solution refers to a set of infinite (but bitcoin is limited) solutions that can be obtained through equations. And each special solution can solve the equation, which is unique. Generally speaking, bitcoin can be regarded as an equation with 2 1 million solutions, but solving this equation requires huge computing power. If you guess this equation correctly, you can get a solution, which is bitcoin.
Taking RMB as an analogy, Bitcoin is equivalent to the serial number of RMB. If you knew the serial number on the bill, you would have this bill.
Someone asked again, why do I know the number and the money is mine? If I spend the money and remember that number in my head, won't it still be mine?
No
Bitcoin network is an online system, without which it is useless. In other words, compare Bitcoin to the seed of the next movie, and compare Bitcoin to online download. No connections, leaving you a lot of seeds.
Bitcoin network is designed as a distributed storage database, and the database is open to everyone: each bitcoin wallet is a node, and these nodes are connected through a P2P network similar to BT download, recording the data in everyone's bitcoin wallet in the world.
Every time a transaction is initiated, it will be broadcast to the entire bitcoin network:
"I am node A, and I have a special solution of 123. Now I want to transfer my money to node (wallet) B "
Other nodes receive this information and compare it with their local databases, and respond:
"After calculation, this is indeed a solution, and I see that A has 123, and node B also exists. I admit this transaction. "
When the number of confirmed nodes reaches a certain number, the transaction is OK.
Next, more and more nodes received this message, and no one raised any objection. This transaction record was accepted by the whole bitcoin network, and from then on, the special solution 123 became the property in B's wallet.
However, the Bitcoin network has a certain fault-tolerant mechanism, which can ensure that even some fraudsters and troublemakers will not affect the operation of the whole network.
Why do so many people speculate for this profit? In the past, Bitcoin still existed as a virtual currency of the Internet, but now it has more and more payment functions of real money, which has also led to the emergence of many emerging miners.
The so-called mining machine is to purchase the mainstream graphics card configuration in the market, then prepare the mining machine and put many graphics cards together for integrated operation. Generally speaking, the mainstream graphics card configuration, such as GTX 1060, can be returned within one month, that is, it will be in a pure profit space after one month, which is why many miners are flocking to it.
If there is a mine disaster, that is, bitcoin depreciates a lot, miners will quickly sell their graphics cards, resulting in many refurbished graphics cards and second-hand graphics cards on the market. For many miners, video cards are more valuable, which is a sure-fire business.
However, Bitcoin has no credit endorsement, only scarcity and uniqueness. Bitcoin is a good speculative variety. Bitcoin prices fluctuate greatly, and high returns are bound to be accompanied by high risks, but it is not a good investment channel for ordinary people.
After all, the essence of Bitcoin is different from other assets. Whether the bubble will burst in the future. This is a completely unknown field. The market chaos brought by bitcoin has affected the normal operation of the domestic economy, so the central bank will crack down on the craze of bitcoin in this way.
In a word, this thing is a new tool created by the U.S. imperialists to attract capital back when the dollar can't substantially bonus hunter.
