When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Nakamoto Tsung", describing the mode of bitcoin
many bitcoin players are attracted by the fact that bitcoin can not be issued at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin
Economists of Keynesian school believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progressbitcoin 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. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
when bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5
first of all, according to its design principle, the total amount of bitcoin will continue to grow until it reaches 21 million more than 100 years later. But the total amount of bitcoin will grow very slowly in the later period. In fact, 87.5% of bitcoin will be "g up" in the first 12 years. Therefore, in terms of the total amount of money, bitcoin will not reach a fixed amount, and its total amount of money will continue to expand, although the speed is getting slower and slower. So it looks like bitcoin is the inflation currency
However, the judgment of deflation or inflation is not based on whether the total amount of money is decreasing or increasing, but on whether the overall price level is falling or rising. The rise of overall price is inflation, and vice versa. In the long run, the issuing mechanism of bitcoin determines that the growth rate of its total amount of money will be far lower than that of social wealth Economists of Keynesian school believe that the continuous decline of prices will make people tend to postpone consumption, because the same dollar can buy more things tomorrow. The rection of consumption will further lead to shrinking demand, unsalable goods, lower prices and a vicious circle of "deflation spiral". Similarly, the deflationary currency itself can appreciate even if it is not deposited in the bank (the purchasing power becomes stronger and stronger), people's willingness to invest will increase, and social proction will fall into a downturn[ 5] Therefore, bitcoin is a currency with deflationary tendency. In bitcoin economies, commodity prices priced with bitcoin will continue to fallbitcoin is a kind of network virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items
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. But in China, bitcoin is forbidden to circulate
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. 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
extended information:
Article 1 of the announcement on preventing the financing risks of token issuance accurately understands the essential attributes of financing activities of token issuance. Token issuance financing refers to the so-called "virtual currency" raised from investors by the financing subject through the illegal sale and circulation of token. In essence, it is an unauthorized illegal public financing behavior, suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities
Relevant departments will closely monitor relevant developments, strengthen cooperation with judicial departments and local governments, strictly enforce the law in accordance with the current working mechanism, and resolutely deal with market chaos. If suspected crimes are found, they will be transferred to judicial organs. The token or "virtual currency" used in token issuance financing is not issued by the monetary authority, does not have such monetary attributes as legal compensation and compulsion, does not have the same legal status as currency, and cannot and should not be used as currency in the marketArticle 2 no organization or indivial may illegally engage in token issuance and financing activities. As of the date of this announcement, all kinds of token issuance and financing activities shall be stopped immediately. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects
Since 2020, bitcoin has become one of the best performing risk assets in all markets. At present, bitcoin has temporarily exceeded the historical peak of 24000 US dollars. Many investors are asking me about bitcoin. Is bitcoin really worth investing in
first of all, it needs to be clarified that the bitcoin investment I am talking about here is a wholly-owned purchase of bitcoin assets, not a leveraged investment
can bitcoin be invested? Should ordinary people buy some bitcoin
in fact, I don't recommend that general investors invest in bitcoin, but it doesn't mean absolutely not
as I said just now, a wholly-owned purchase of bitcoin assets can actually balance risk and return. If ordinary investors have tens of thousands of idle assets in their hands and can accept high-risk investment psychologically, that is to say, even if they lose tens of thousands of yuan completely, they can accept it in their hearts, then there is no problem in charging high returns by investing in bitcoin
the current price of bitcoin is the highest level in history, but this does not mean that bitcoin has no investment space. According to the general estimation, bitcoin will reach the highest level in the future. The value between us $300000 and US $500000, that is to say, even if bitcoin has a significant decline in the short term in the future, the value potential of the investment in the long term is also acceptable
in the short term, although it is generally believed that the fair price of bitcoin will reach about US $10000 to US $12000 after the global central bank's release of water, the current price is also overvalued, which means that bitcoin will decline significantly after a period of time, but it will continue to rise e to the market sentiment before returning to the apartment price, It's likely to challenge $30000
after all, before 2020, the fair price of bitcoin was about $6000, but in 2017, it also challenged nearly $20000
to sum up, if you can accept high-risk investment and have idle money that you don't care to lose, then wholly-owned investment in bitcoin is a choice of asset allocation

physics developed to the end of the 19th century, which can be said to be quite perfect and mature. All physical phenomena seem to be able to get satisfactory answers from the corresponding theories. For example, all mechanical phenomena can be explained from classical mechanics in principle. Newtonian mechanics and analytical mechanics have become effective tools to solve mechanical problems. For the analysis of electromagnetic phenomena, Maxwell's electromagnetic field theory has been formed, which is the unified theory of electromagnetic field. This theory can also be used to explain the basic problems of wave optics. As for the thermal phenomenon, there are phenomenological thermodynamics and statistical mechanics theories, which can make a reasonable explanation for the macroscopic law of the thermal motion of matter and the microscopic statistical law of the thermal motion of molecules. In a word, the classical physics building with classical mechanics, classical electromagnetic theory and classical statistical mechanics as the three pillars has been built, and the foundation is solid and magnificent! Under such circumstances, it is no wonder that physicists will feel intoxicated and feel that physics has achieved great success, thus asserting that they will not be able to do anything in the future. At that time, this kind of thought not only existed universally in physics, but also had a long history
Planck made a speech in 1924. In his speech, he recalled that when he was studying physics at the University of Munich in 1875, his physics teacher P. Jolie (1809-1884) advised him not to study pure theory, because physics "is a highly developed and almost perfect science". Now this science "seems very close to taking the most stable form.". Perhaps, there is a st or a small bubble in a corner, which can be studied and classified. However, as a complete system, it is established firmly enough. And theoretical physics is clearly approaching the level of perfection that geometry has had for hundreds of years. " Another famous teacher of Planck, G? Kirchhoff (1824-1887) also said a similar thing, he said that "physics has done nothing but add a few numbers after the decimal point of the known law." Although Kelvin's evaluation of the achievements of physics is too extreme, he can find "two dark clouds" in the clear sky and is worried about them, which shows that he is far sighted. The history of the development of physics shows that it is these two small dark clouds that finally led to a big storm
the first dark cloud -- Michelson Morey experiment and the collapse of "Ether" theory. Sunlight passes through a vacuum to the earth, and light from galaxies billions of light-years away also passes through space to the earth. Why can light wave propagate in vacuum? What is its medium of transmission? Physicists have found a medium for light transmission - "Ether"
Aristotle, the ancient Greek philosopher, first proposed "Ether". Aristotle thought that the lower boundary was composed of fire, water, earth and air; Add the fifth element to the upper bound, "Ether". After Newton discovered the universal gravitation, he met a difficult problem: in the vacuum of the universe, what medium does gravitation propagate? In order to find a complete solution, Newton revived Aristotle's "Ether" theory, and believed that "Ether" was the propagation medium of gravity in the cosmic vacuum. Later, physicists developed the theory of "Ether", believing that "Ether" is also the medium of light wave propagation. Light, like gravity, is transmitted by the ether. They also assume that the whole universe is full of "Ether", which is a thin, imperceptible medium composed of very small elastic spheres. In the 19th century, Maxwell's electromagnetic theory also described the medium that transmits light and electromagnetic waves as a kind of "Ether" that has no weight and can absolutely penetrate“ "Ether" not only has the nature of electromagnetism, but also is the transmitter of electromagnetic effect, and also has the nature of mechanical mechanics. It is an absolutely static reference frame, and all movements are relative to it. In this way, the electromagnetic theory is consistent with Newtonian mechanics“ The concept that "Ether" is the common carrier of light, electricity and magnetism is generally accepted by people, forming a "etherology"
however, after confirming the existence of "Ether", a new problem arises: if the earth moves around the sun at the speed of 30 kilometers per second, it must encounter the wind of 30 kilometers per second. At the same time, it must also have an impact on the propagation of light. The emergence of this problem causes people to explore whether "yitaifeng" exists or not< In 1887, Michelson (1852-1931) cooperated with American chemist and physicist Murray (1838-1923) to carry out a famous experiment in Cleveland: "Michelson Murray experiment", namely "ether drift experiment". The experimental results show that no matter the direction of the earth's motion is the same as or opposite to the direction of light, the measured speed of light is the same, and there is no relative motion between the earth and the "Ether". Therefore, there is no "Ether" or "absolutely static space". Because this experiment is easy to understand in theory and accurate and reliable in method, there is no doubt that the experimental result denies the existence of "Ether"
the Michelson Morey experiment puts scientists in a dilemma. They may have to abandon the etheric theory that has explained many phenomena of electromagnetism and light. If they dare not give up ether, then they must give up Copernican's theory of earth movement, which is older than etherology. Classical physics is at a loss in the face of this famous experiment
the second dark cloud -- blackbody radiation and "ultraviolet disaster"
at the same temperature, the brightness and color (wavelength) of different objects are different. Dark objects have strong ability to absorb radiation. For example, the absorption rate of coal to electromagnetic wave can reach about 80%. The so-called "blackbody" refers to the ideal object that can absorb all external radiation without any reflection and transmission, and the absorptivity is 100%. There is no real blackbody, but a cavity with a small hole on its surface can be regarded as an approximate blackbody. Because the radiation entering the cavity through the small hole will not leak out from the small hole after many times of reflection and absorption in the cavity
at the end of the 19th century, lummer (1860-1925) and others' famous experiment blackbody radiation experiment found that the energy of blackbody radiation is not continuous, and its distribution according to wavelength is only related to the temperature of blackbody. From the perspective of classical physics, the results of this experiment are incredible
how to explain the results of blackbody radiation experiment? At that time, people started from classical physics to find the laws of experiments. Incorrect premise and starting point lead to failure in the end. For example, Wien, a German physicist, established a formula for the distribution of blackbody radiation energy according to wavelength, but this formula is only consistent with the experimental facts when the wavelength is relatively short and the temperature is relatively low. British physicist Rayleigh and physicist, astronomer King think that energy is a continuous change of physical quantity, establish the blackbody radiation formula which is more consistent with the experimental facts when the wavelength is longer and the temperature is higher. However, according to the Rayleigh gins formula, in the short wavelength region (ultraviolet region), the radiation intensity can increase endlessly with the shortening of the wavelength, which is far from the experimental data. So this failure was called "ultraviolet disaster" by Ellen fester. Its failure undoubtedly indicates the failure of classical physics theory in the problem of blackbody radiation, so it is also the "disaster" of the whole classical physics.
at present, there are two ways for ordinary people to enter the bitcoin instry, one is to buy professional machinery and equipment to "mine" and the other is through trading and other exchange methods
however, e to the design of the algorithm, the bitcoin value generated by bitcoin will be halved every four years. From 2013 to 2016, 25 bitcoins will be generated every ten minutes on average, and from 2017, the number will be reced to 12.5. By 2030, after 20 million bitcoins have been mined, the remaining 1 million bitcoins will probably take decades to be mined; At the same time, with the increasing difficulty of mining, the price of advanced mining machine is higher and higher, which sets a big "threshold" for "mining". It is understood that as the blue ocean of "mining" has long disappeared, coupled with the soaring price of bitcoin, many "miners" directly switch to speculation in bitcoin and wait for appreciation before selling it
the trading process of bitcoin is similar to that of stocks
e to the attractive performance of bitcoin in the early stage, "speculation on bitcoin" has become increasingly popular in China. In an interview with the media, Li Qiyuan, chief executive of bitcoin China, said that in recent years, the number of new registered users and user activity of bitcoin China have improved significantly, and the upward trend is very obvious, which shows that more and more people are contacting bitcoin
at present, the mainstream trading platforms in China include bitcoin China, okcoin, fire coin, etc. the process of trading bitcoin is very similar to buying and selling stocks. Take huocoin.com as an example. After registration, you can start to buy bitcoin by recharging RMB to the website account, and the purchased bitcoin is stored in the website trading platform. If you sell successfully, you can also withdraw RMB from your account to your Alipay or bank account. Different from the previous 0.3% handling charge for each transaction, the domestic major bitcoin trading platforms have successively cancelled the transaction handling charge. However, a 0.4% service charge is still required for recharging through TenPay or online banking. If RMB is withdrawn, the withdrawal service charge will be charged according to the bank transfer rate from the second withdrawal every day.
blockchain is a technology implementation of distributed storage based on cryptography, and its significance is to ensure the security and reliability of information circulation process, but blockchain is not absolutely perfect, it depends on many factors
the benefits of blockchain. It has to be said that as a supplement to the social credit system, blockchain has natural advantages
1. Smart contract, which is the foundation of blockchain platform. With the help of smart contracts, rules can be applied safely when dealing with transactions. They can be used to automatically perform verification steps to encode conditions previously contained in signed physical contracts
2. Distributed storage, distributed storage system, is to store data in multiple independent devices. Traditional network storage system uses centralized storage server to store all data. Storage server becomes the bottleneck of system performance and the focus of reliability and security, which can not meet the needs of large-scale storage applications
3. The pursuit of capital and the pursuit of profit by capital are just like Satan's hell fire burning all the evil sources. The greed of capital will surely threaten all the hype concepts and reap the green of leeks. Good capital injection can also bring back the rapid development of the instry
"blockchain is the most popular fintech (Financial Technology). This innovative technology from bitcoin is subverting the financial instry and our lives. In 2015, blockchain became the highest financing sector in US venture capital, breaking through US $1 billion. This kind of hot financing scene only appears in foreign countries“ Few people in China really understand blockchain technology, "said a senior practitioner. This is the reality. In China, most of the companies that are known as blockchain technology are unwilling to give up the dividend of bitcoin and still stay in the primary stage of currency speculation; The transformation of the financial sector, more in essence, is just speculation concept stocks; There are few people who sincerely do technology. "
"blockchain is the underlying technology of bitcoin, which solves the process of bitcoin from 0 to 1. At this stage, blockchain has become a high-frequency word in the big and small science and technology summit, and its popularity is no less than that of "o2o" in the previous two years. When people are discussing blockchain, they are more concerned about how to use blockchain, and they have no doubt about the application value of blockchain. " Blockchain is a decentralized trust mechanism. In the past, blockchain was mainly used in bitcoin. Until the last half year, blockchain has graally started to have some other applications, especially in the financial field
blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust. Generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
bitcoin is one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. The structure of blockchain storage data is a chain composed of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin. Through cluster or cloud mode operation, the nodes can expand horizontally, and continuously improve the overall network performance based on benign competition
bitcoin has no legal compensation and compulsion, and its circulation range is limited and unstable. Bitcoin also has strong substitutability, so it is difficult to be a general equivalent. No matter how skillful the blockchain technology is, it is impossible to proce a national currency, and the mass investors should not follow suit.
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
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
