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
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
extended data:
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
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
the bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

bitcoin is a new type of virtual currency, which is generated by a large number of calculations based on special algorithms. According to rigorous calculations, the stock of bitcoin is limited, with a total of 21 million, no more or less. After being created, bitcoin has rapidly become a "fixed asset" pursued by Internet speculators
in February 2014, mtgox, the world's largest trading platform, went bankrupt, casting a shadow on the whole bitcoin instry. Since the middle of 2014, the price of bitcoin has been in a downward trend for a long time

1、 Common analysis of virtual currency (1) bitcoin solution is designed and created by Japanese programmer Nakamoto (alias) in 2009, and it is the most successful and controversial network currency at present. Bitcoin scheme is based on P2P network architecture, which has been operating in the world, and can be used for all kinds of virtual and real goods and services transactions
In theory, if the existence of network currency affects the demand for the central bank's liabilities, and then interferes with the central bank's open market operation, it will have an impact on a country's monetary policy and price stability. However, from a practical point of view, the premise of network currency affecting price stability includes the following three aspects:(1) from the analysis of the impact on the amount of money, although it is difficult to analyze the extent to which the network currency scheme creates money in the case of lack of information
However,however, most Internet money systems operate in prepaid mode, that is, issuing Internet money when the real money is exchanged in and withdrawing money when the real money is exchanged out. In the famous network currency scheme, the supply of money is stable and the supply is small, but we still need to be vigilant whether it can ensure that the money supply will maintain a stable level in the long run, and the impact of the change of exchange rate between network currency and real currency
(2) from the analysis of the impact on the speed of money circulation, the use of cash and money statistics, the impact of the technological innovation brought by the network currency scheme on the speed of money circulation is not clear
as an Internet instry, it largely depends on the number of active internet currency scheme users. If the network currency is widely accepted, it will have a substitution effect on the real currency of the central bank, thus recing the use of cash in transactions
in this case, the scale of the central bank's balance sheet will be reced, and its ability to influence short-term interest rates will also be weakened. The central bank will need to fight against risks through ways such as setting minimum reserves for cyber currencies. Substitution effect will aggravate the difficulty of monetary statistics and affect the relationship between monetary statistics and inflation, which is not concive to the realization of long-term price stability. In addition, the issuance of network currency outside the central bank and the expansion of virtual credit will have an impact on the central bank's interest rate decision in the economy and weaken the central bank's monetary control
(3) from the analysis of the interaction between network currency and real economy, network currency can act as a real commodity trading medium and have an impact on real GDP
The influence of network money on real money supply depends on two aspects: one is the substitution effect of virtual economy on real economy; the other is the substitution effect of virtual economy on real economy; The second is the crowding out effect of Internet money on real money, that is, with the increase of the total amount of Internet money, the amount of cash held by the public in real life decreases, resulting in the decrease of cash / deposit ratio and the increase of money multiplier. In reality, the network virtual currency scheme will not affect the price stability at this stage, and the money flow speed will not be significantly affected in the short and medium term. However, the interaction between network currency and real economy deserves attention (2) financial stability risk when the virtual currency scheme operates outside the banking system, the most important factor of financial instability lies in its connection with the real economy, namely exchange rate and exchange market. Obviously, the closed network currency scheme and the one-way flow network currency scheme are not affected, so we should focus on the two-way flow network currency scheme. The value of two-way network currency depends on the level of money supply and demand in the exchange market. A big difference between network currency and real currency is that the network currency scheme is not based on the country or currency region, and the influence of virtual economy intensity, trade or proction capacity on its exchange rate is limited. The price of virtual money and its fluctuation depend on five factors:(1) money supply and other actions taken by currency issuers. For example: to achieve a fixed or semi fixed exchange rate by intervening in the market
(2) the network currency scheme shows network externality, and its monetary value depends on the number of users and merchants. As the number of consumers and businesses increases, their monetary value will increase accordingly. In addition, the exchange rate of network currency with small transaction volume fluctuates more(3) the virtual community with clear and transparent policies and advanced security measures is easier to boost confidence and the currency is stronger
(4) the reputation of network currency issuers in fulfilling their commitments. There is no "lender of last resort" in the virtual community, and the trust gained by the issuer is crucial to the exchange rate of internet currency
(5)
speculation on the future value of Internet money and cyber attacks on virtual communities. Due to the immaturity of the system, low trading, speculative activities and network attacks, the two-way network currency scheme is inherently unstable
qualitative. At present, the trading volume of these network currencies is small and the correlation with the real economy is low, so the stability of the financial system will not be affected. However, if Internet money becomes a substitute for traditional money in the future, it will bring instability to the financial system and even distort the relative prices of goods and services. The impact of network currency system on the financial system largely depends on the number of active users and the number of merchants who are willing to accept virtual currency for real transactions. In addition, virtual currency has only exchange value and no use value. Generally, network currency is not based on assets with intrinsic value and is not supported by central bank credit. At present, these network monetary systems are not allowed to lend
or borrow funds, so it can not pose a threat to the stability of the financial system, but we should pay close attention to its development. If there is any change in the future, it will undoubtedly have an impact on the financial system
in a specific virtual community, virtual currency payment activities have evolved into a "real" payment system, facing typical risks related to the payment system: credit risk, liquidity risk, operational risk and legal risk. The nature, scale and ration of these risks are largely determined by the design of the system or the degree of lack of liquidity, so it is difficult for the network virtual currency scheme to avoid or control these risks. According to the core principles of payment system (CP) issued by the bank for International Settlements (BIS), the network virtual currency scheme does not conform to most of the contents of CP, and does not belong to the systemically important payment system. Therefore, it will not cause
or transmit shocks in the global financial system. At present, there is no systematic risk in the network currency system outside these virtual communities
2. Lack of corresponding supervision and protection mechanism
in the real economy, the central bank plays the role of lender of last resort and has no default risk, so it can take actions in the case of payment crisis or unpredictable liquidity shortage to avoid chain reaction. However, in the network virtual currency scheme
it is impossible to use network currency as settlement asset. Because network currency simply depends on the credibility of the issuer, it can not be widely accepted as a means of payment, so network currency can not be regarded as a safe currency. In addition, commercial banks are required to accept prudential supervision, which reces the possibility of default, and the security of money in commercial bank accounts is higher than that of network currency. A fundamental risk of network currency is that the settlement institution of network currency scheme is not subject to any supervision, no institution is responsible for its behavior, and there is no investor / depositor protection mechanism, which causes the user to bear all the risks
supervision and the anonymity, invisibility and difficulty in tracking of its transactions, the network virtual currency scheme is very easy to be used by terrorist activities, fraud, money laundering and other illegal activities. At present, many government departments in many countries are considering whether to recognize or
legalize these virtual schemes and bring them into the scope of supervision, so as to support the innovation of currency and payment forms, protect the rights and interests of consumers and financial stability, and inhibit the use of virtual currency schemes to engage in criminal activities
at present, the uncertainty of the legal status of the virtual currency scheme may also bring challenges to the government authorities (5) reputation risk of monetary authority the reputation of Monetary Authority (central bank) is the key factor to determine the effectiveness of monetary policy. The public's trust in fiat money is closely related to the image of the central bank, which pays close attention to its reputation. The ECB defines reputation risk as the risk of deterioration of reputation, credit or public image. As the network currency scheme is related to money and payment, it is generally believed that it belongs to the responsibility of the central bank, so we should be alert to the reputation risk it may bring to the central bank. However, in the case of small scale, the impact of the failure of the network currency scheme is limited, but its high volatility and instability also aggravate the possibility of failure and attract extensive media coverage. If the network currency is allowed to develop continuously without
regulation, the central bank may be considered as dereliction of ty and affect its reputation (6) the risk of investors' loss
for exchange value, the public has a higher recognition of the investment value of network virtual currency, and it is investment based transactions that accelerate the formation of virtual currency market. Like other investment markets, participants in virtual money market will also face potential losses caused by market risk, credit risk and policy risk. Take bitcoin as an example: from 2009 to early 2010, bitcoin was worthless; In the summer of 2010, bitcoin trading began to enter the golden
period. As the supply was far less than the demand, the value of online trading began to rise. In early November, bitcoin was silent at 29 cents for many days, and then jumped to 36 cents; In February 2011, bitcoin continued to appreciate, and its exchange rate with us dollar
reached 1:1; In 2013, the price of bitcoin achieved a "Big Bang" growth, and hit US $1242 on November 29, 2013, surpassing the gold price of US $1241.98/ounce in the same period. Fierce price fluctuations make market participants face huge speculative risks. Unlike mature capital markets such as stocks and bonds, the depth of bitcoin market is insufficient, and it is mainly held in the hands of large investors with low degree of diversification. Bitcoin price is easily affected by large investors' buying and selling behavior, and also easily manipulated by speculators. At the same time, different countries have different attitudes towards bitcoin, Germany, the United States and other countries hold an open and supportive attitude, and Thailand, Brazil and other countries regard bitcoin related activities
as illegal. Every country's attitude and measures will have a significant impact on the price of bitcoin, especially in the short term
virtual currency is always inferior to real currency< br />
in October 2013, bitcoin Bank of Australia was attacked by hackers, with a loss value of more than US $1 million. This incident has aroused the concern of bitcoin security in Australia. The Reserve Bank of Australia and the Australian tax office have said they want a virtual currency tax like a business transfer tax
Bangladesh
the Central Bank of Bangladesh banned the use of virtual currency in September 2014. Using bitcoin will be punished by law
Brazil
Brazil is one of the few countries in the world that has enacted laws related to electronic currency payment systems. Brazil has not banned bitcoin
Bolivia
for regulatory reasons, the Central Bank of Bolivia (BCB) has banned the use of bitcoin. BCB believes cryptocurrency will help business entities evade taxes
Canada
bitcoin is not considered legal, that is, bitcoin is not recognized by Canadian law. Canada's tax authorities plan to implement the same tax plan as barter trade and speculative trading for the bitcoin
China
China is one of the few countries in the world that ban bitcoin completely and prohibit financial institutions and banks from dealing with bitcoin transactions. In December 2013, the people's Bank of China issued a notice calling bitcoin & quot; Virtual goods;, And prevent it from becoming money
trading has been suspended
Ecuador has banned bitcoin, but it has chosen to set up a new state-owned electronic currency and monetary system, and the currency will be protected by the assets of the Central Bank of Ecuador
EU
at present, the EU still has different views on the classification of bitcoin. In October 2012, the European Central Bank's report on virtual currency concerns the legality of bitcoin under the EU legal framework. The European Banking Regulatory Authority issued a bitcoin risk warning, saying that the use of bitcoin has not been restricted at present
Finland
Finland has relevant regulations for the use of virtual currencies such as bitcoin. The relevant regulations are issued by the Finnish tax authority Vero skatt. Any gains arising from bitcoin transactions will be subject to capital gains tax
Hong Kong
Hong Kong has no regulations for bitcoin or any other virtual currency. However, the government is closely monitoring the use of bitcoin to prohibit money laundering, fraud and other illegal activities
India
India does not explicitly stipulate or prohibit the use of bitcoin. However, the Reserve Bank of India (RBI), equivalent to the Central Bank of India, has been forced to shut down India's largest bitcoin trading platform after it issued a notice that the use of bitcoin could cause money laundering and security problems
Israel
the Israeli tax authority is considering levying income tax on bitcoin transactions. Israeli banks even blackmail bitcoin payments
Kyrgyz
Kyrgyz central bank has banned the use of digital currency and bitcoin for the reasons of lack of centralized management, high currency risk and legal problems
Russia
the Central Bank of Russia believes that bitcoin may be used for money laundering and terrorist financing. Therefore, the Russian government banned the use of bitcoin
Taiwan
Taiwan's financial supervision commission is concerned about the uncertainty and speculation of bitcoin, so Taiwan opposes the installation of bitcoin ATM
UK
at present, there are no relevant regulations for the bitcoin. Profits or losses from bitcoin transactions are subject to capital gains tax, while the purchase of bitcoin is still subject to VAT
the U.S.
the U.S. is probably the most supportive country for virtual currencies such as bitcoin. There are no final rules on bitcoin. However, there are also many new rules for the establishment of bitcoin management framework.

3. 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
don't be cheated any more. The air bitcoin club is a pyramid scheme
Since Xiaolu entered the circle, people often ask Xiaolu what is the difference between q-coin and bitcoin. Emmm, although the answer to this question is very simple, it's a bit troublesome to explain it. So Xiaolu should write an article today to explain it well
I don't know what fawn said. Do you understand? If you have any questions, please leave a message and communicate with Xiaolu
If we can go back to 2010, a lot of things can be invested (of course, buy Germany 7:1 Brazil, buy Leicester City Premier League champion, buy Knights 1-3 great reversal warriors, etc.), it's very exciting to think about it
If I can go back to 2010, I will first invest in bitcoin. In 2009, bitcoin was born. In 2010, bitcoin was still very cheap. I wanted to buy as much as I had, and I wanted to buy all kinds of borrowed money. You know, in the distant year of 2009, when the price was less than one cent, a dollar could be converted into 1300 bitcoins
