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

bitcoin is an e-money payment system based on the global network
bitcoin is an e-money system based on the global decentralized network system, without the participation of central banks and third-party institutions, with a fixed total amount.

English: bitcoin currency symbol: abbreviation: BTC or XBT

Introction to bitcoin by wiki
different from traditional currency, bitcoin's operation mechanism does not rely on the support or credit guarantee of central bank, government and enterprise, but on the network agreement reached with seed files in the network, which is a decentralized and self-improvement monetary system, Theoretically, it ensures that no one, institution or government can control the total amount of bitcoin or create inflation. Its total amount of money graally increased at the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140<

Introction to bitcoin in network
bitcoin is based on a set of cipher codes and generated by complex algorithms. This rule is not interfered by any indivial or organization and is decentralized; Anyone can download and run the bitcoin client to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P distributed network. The generation and consumption of each bitcoin will be recorded through the P2P distributed network and informed to the whole network. There is no possibility of forgery. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction<

the difference between bitcoin and bitcoin
it should be noted that

in English, the words bitcoin and bitcoin represent two concepts of payment network and monetary unit

bitcoin starting with capital B represents bitcoin network system or bitcoin network protocol, which is a payment system based on decentralized network

you can simply understand bitcoin as a public accounting system built on the Internet and not manipulated by any third party. Bitcoin, which starts with lowercase B, refers to the digital currency (e-money, e-cash, cryptocurrency) built on bitcoin network. Bitcoin is the payment accounting unit built in bitcoin payment system. We call bitcoin the network system that proces bitcoin<

in Chinese, bitcoin and bitcoin are both called bitcoin without distinction in many places

its main features are as follows:
1. Decentralization

bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom< Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3. Exclusive ownership

private key is required to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

4. Low transaction cost

bitcoin can be remitted free of charge, but in the end, a small transaction fee will be charged for each transaction to ensure faster transaction execution

5. No hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay<

6. Bitcoin is not completely anonymous

it will take some time to protect privacy when using bitcoin. All bitcoin transactions are publicly and permanently stored in the network, which means that anyone can view the balance and transaction records in any bitcoin address. Unless the bitcoin holder discloses personal information ring the transaction, the bitcoin address will not be associated with the real identity of the bitcoin holder. This is why it is recommended that bitcoin holders use multiple bitcoin addresses; In fact, you should create a new address each time to receive bitcoin. This is especially important when using bitcoin in public places, such as on websites. In addition, you can also consider using tools like tor to hide your IP address from being recorded.

7. Bitcoin is still experimental

bitcoin is an experimental new currency in active development. Although its experimentality is diminishing with its increasing usage, remember that bitcoin is a new invention, exploring ideas that have never been tried before, so no one can predict the future of bitcoin.

Bitcoin is the first distributed virtual currency

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 assign a private key and a public key. You need to back up the 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

extended information:

as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code

in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred

however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties

naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes

it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations

4. Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

under her leadership, Vicat not only inherits the characteristics of bitcoin decentralization, but also the stock is determined by algorithm. For institutional investors, Vicat is more strict in anonymity, borderless, not easy to crack and additional issuance. Based on the above principles, as long as the Vicat currency maintains proper liquidity, its own scarcity ensures the overall stable and upward price trend of the currency without the influx of a large number of hot money. In addition, with the overall economic downturn in Europe and the United States, gold prices continue to fluctuate. Stable virtual currency has become the main choice of a large number of institutional investors.

9. Greedy, and
in the early stage of bitcoin economic development, the market is not mature, speculative activities sometimes expand market volatility, rece market trust, damage bitcoin economic development: 1) easy to be manipulated by makers. Due to the small scale of bitcoin market, the lack of knowledge and experience and psychological quality of practitioners in the early stage of development, the market is easy to be dominated by big funds, cooperate with news and futures leverage, and create and expand price fluctuation arbitrage; 2) Policy city and information city. Due to the poor transparency of the domestic institutional environment and the strong arbitrariness of the decision-making mechanism, there is great uncertainty and flexibility in the expectation and interpretation of policies, which enhances the uncertainty of the market and is even used to create market fluctuations and make profits at low cost; 3) Zero handling charge leads to excessive liquidity. In the case of small market scale, immature practitioners and poor institutional environment, the zero handling charge of the trading platform endows the market with excessive liquidity, expands the above artificial market fluctuations, increases the profits of the fluctuation makers, and forms negative incentives; 4) Speculative demand is separated from application and investment. The above vicious speculation benefits from market defects, and naturally tends to maintain these defects, thus destroying the market mechanism and business environment, occupying a lot of manpower, intelligence and capital to engage in zero sum game, even negative sum game, seriously hindering the application and investment of bitcoin that should be promoted.
