Generally speaking, bitcoin

1.

The earliest is a kind of network virtual currency. It is characterized by decentralization, anonymity, and 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. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar

< H2 > extended information:

bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. 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

starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin

2. 1. Bitcoin is a kind of "electronic currency". mining machine is a special bitcoin computing tool for downloading
2. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
3. It's very valuable. In terms of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you will have it. At present, one bitcoin is worth $1044
4. To mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
finally, I would like to warn you that
bit will one day become US $500000

3. I will analyze my personal cognition of the value of comparative currency from two perspectives:
1. A little thought on currency
at present, the currency issued by all countries in the world is basically credit currency. For example, the US dollar has been decoupled from gold since the Bretton Woods system. It is generally believed that the value of the modern dollar is supported by the national credit, or national strength and military strength of the United States
however, this is specious. Because the national strength and military strength of the United States cannot be quantified, who can tell me how much the national strength and military strength of the United States are worth? Since it is impossible to quantify, how can we ensure that the US dollar is not printed too much? In fact, there is no guarantee. On the other hand, it says "in God we trust" on the dollar, which is to tell you clearly that the dollar is actually a kind of faith. It's like trump supporters shouting, "America! USA! ", People's trust in the dollar is not purely rational, but a mixture of rationality, pride, sacredness, speciousness and habitual thinking
and this kind of trust is also fragile. In recent years, for example, the Thai baht and ruble have dropped by 40% or 50% overnight, which is also common. Even more outrageous, for example, the government of the Republic of China basically cheated on the golden yuan
bitcoin is also true. Its value comes from trust, but it is not backed by the government's credit endorsement. The letter of bitcoin is a more pure letter, because it is more invisible than the legal coin, but there is a small group of people who believe in it, such as me. This kind of letter comes from the simplicity and strength of bitcoin technology, from the ideas beyond the times contained in it, from the dissatisfaction with the existing monetary system, and from the natural yearning for progress of human beings
2. Bitcoin price and reflexivity
Buffett's value investment theory is very popular: because of people's fear or greed, the price of a thing may temporarily be higher or lower than its value, but it will eventually return to the value itself
Soros's view is that because of the fragility of human nature, a thing can never return to its value. That is to say, the correction must be over correct. When the value of a thing is absolutely undervalued, then in the process of rising, people's awareness of its rising is constantly strengthened, which often leads to crazy buying, and the final price will rise to its own value, and vice versa
in this process, the rise of price leads to people's pursuit of a thing, and people's rising expectation will continue to push up the price of this thing
Soros calls it reflexivity
for example, there is a prophet in the village. He told us that gold would go up and we should go to buy gold. Everyone flocked to buy gold. The supply of gold was in short supply, and it rose as expected. So everyone said that the prophet was right
this process has nothing to do with the basic value of gold or the actual demand for gold
if you look at it with a magnifying glass. In this process, the bullish view of gold is constantly strengthened. Because gold also rose in the process. If in the first rise callback, someone sold. When it goes higher for the second time, this person will feel that his operation is particularly stupid, so he will not easily sell when he buys again next time. Even if he sells again next time, there will always be a time when he will "learn to be smart" and no longer sell
man is also a social animal. So this expectation of rising will continue to spread and "learn" from each other, aggravating this weakness of human nature
often when a bubble burst, most people could not escape. A few rational people can run away, a few win the majority and make a lot of money. In the book mob, it is said that the IQ of a group is often lower than that of a person. In management, this is called herding. In China's stock market, this is called "retail dividend". You don't see how many people earn money every day on the platform, even wealth is free.

Bitcoin is a kind of electronic cryptocurrency based on blockchain, which is decentralized, global, and does not need third-party institutions or indivials. Bitcoin was invented and founded by Nakamoto (pseudonym) on January 3, 2009, based on the peer-to-peer network without borders, using consensus initiative open source software. It is the ancestor of cryptocurrency and blockchain, and is also the cryptocurrency with the highest popularity and market value at present

generally speaking, bitcoin is a digital currency with a total amount of 21 million, which has the characteristics of decentralization, globalization, anonymity and so on, just like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields

{rrrrrrr}

extended materials:

the global financial crisis broke out in 2008. On November 1, 2008, a person who called himself Nakamoto published bitcoin white paper "bitcoin: a peer-to-peer e-cash system" on the P2P foundation website, stating his new idea of e-currency bitcoin. On January 3, 2009, bitcoin Genesis block was born

compared with fiat money, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or collect bitcoin, And in the transaction process, foreigners can not identify the user's identity information

as a standardized, globalized, highly volatile, 24-hour and never-ending trading target, bitcoin is more volatile than stocks, foreign exchange, precious metals and other electronic disk targets; In terms of standardized trading, soaring history and future prospects, it is better than the physical speculation targets such as stamps and coins, garlic, Pu'er tea and Huangli wood, so it has attracted a lot of hot money to participate in the speculation

at present, the funds attracted by bitcoin as the target of speculation far exceed the funds attracted by the payment system. At least half of the price of each yuan is the value of the target of speculation

6. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system, which is a kind of virtual currency.

7. Bitcoin
the initials of bitcoin are used to represent the concept of bitcoin or the whole bitcoin network itself. For example: "today I learned something about the bitcoin agreement."
bitcoin without capital letters indicates a unit of account. For example: "I transferred 10 bitcoin today." The unit is also usually abbreviated as BTC or XBT
bitcoin address
a bitcoin address is like a physical address or an email address. This is the only information you need to provide when someone pays you bitcoin. An important difference, however, is that each address should only be used for a single transaction
peer to peer network
peer to peer network is a system that allows a single node to interact directly with other nodes, so that the whole system can operate like an organized collective. For bitcoin, the bitcoin network is built in such a way that each user is spreading the transactions of other users. And importantly, there is no need for the bank to be a third party
hash rate
hash rate is a measure of bitcoin network processing capacity. In order to ensure security, bitcoin network must carry out a lot of mathematical operations. When the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
transaction confirmation
transaction confirmation means that a transaction has been processed by the network and is unlikely to be revoked. When a transaction is included in a block, an acknowledgement is received, and each subsequent block corresponds to an acknowledgement. For a small amount of transaction, a single confirmation can be regarded as safe. However, for a large amount of transaction such as US $1000, it is reasonable to wait for more than six confirmations. Each confirmation exponentially reces the risk of cancellation
blockchain
blockchain is a public record of bitcoin transactions in chronological order. The block chain is shared by all bitcoin users. It is used to verify the permanence of bitcoin transactions and prevent double consumption
cryptography
cryptography is a branch of mathematics, which allows us to create mathematical proofs that can provide high security. Cryptography is also used in e-commerce and online banking. For bitcoin, cryptography is used to ensure that no one can use the money in other people's wallets or break the blockchain. Cryptography is also used to encrypt wallets, so you can't use wallets without a password<
signature
cryptography signature is a mathematical mechanism for people to prove ownership. For bitcoin, a bitcoin wallet is associated with its private key by some mathematical magic. When your bitcoin software signs a transaction with the corresponding private key, the whole network will know that the signature matches the spent bitcoin. However, no one in the world can guess your private key to steal your hard-earned bitcoin
wallet
bitcoin wallet is roughly the equivalent of physical wallet in bitcoin network. The wallet actually contains your private key, which allows you to consume the bitcoin allocated to the wallet in the block chain. Like a real wallet, each bitcoin wallet displays the total balance of all bitcoins it controls and allows you to pay someone a certain amount of bitcoin. This is different from the credit card used by merchants to dect money
block
a block is a record in the block chain, which contains and confirms the transactions to be processed. On average, a new block containing transactions is added to the block chain by mining every 10 minutes
double consumption
If a malicious user tries to pay bitcoin to two different payees at the same time, it is called Double consumption. Bitcoin mining and blockchain will reach an agreement on the network that one of the two deals will be confirmed and considered valid
private key
the private key is a secret data block that proves that you have the right to consume bitcoin from a specific wallet. It is implemented through a cryptographic signature. If you are using wallet software, your private key is stored in your computer; If you are using an online wallet, your private key is stored on a remote server. Don't disclose private keys, because they allow you to consume the bitcoin in the corresponding bitcoin wallet
Mining
bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security. As a reward for their service, miners can get the Commission included in the transaction they confirm, as well as the newly created bitcoin. Mining is a professional and competitive market. The bonus is divided according to the amount of calculation. Not all bitcoin users mine, and it's not easy to make money from mining
bit
bit is a common unit used to indicate the sub unit of a bitcoin - 1000000 bit is equal to 1 bitcoin (BTC or B & 8422;), This unit is more convenient for marking tips, goods and service prices
BTC
BTC is used to mark a bitcoin (B & 8422;) The common unit of.

8. Bitcoin = virtual network gold coin (similar to Q coin)
getting method: Mining (actually, it's a way to decipher digital games, which requires special equipment, about 600000 US dollars)
