The undisclosed story of deep net bitcoin and Silk Road
Let's start with a simple conclusion: a year ago, the data showed that there were about 500000 BTC
two American brothers, Cameron winkleworth and Taylor winkleworth, claiming that they owned 1% of bitcoin [1] 1% of the world's bitcoin? At present, the total amount of bitcoin in the world is about 12 million, that is to say, the two brothers hold about 120000 bitcoins< maybe you don't think it's worth much, but note that the starting price of bitcoin for these two people is less than $10 / bitcoin
Please note that entities are used instead of people. In the analysis method of this paper, bitcoin wallets that may belong to the same owner are divided into the same entity, which may be not only a person, but also a trading organization like Mt. GOx in addition, through the analysis of the most active entity table given in this paper, the income of the people with the most income (excluding expenses) is less than 700000 BTC. In other words, the person with the most bitcoin will hold no more than 700000 bitcoins. How many people in the world own bitcoins? The paper concludes that as of May 13, 2012, 1.85 million entities hold bitcoin. If we assume that bitcoin users have grown linearly since the advent of bitcoin (January 2009), the current number should be 2.5 million. Because the number of entities is counted on paper, the actual number of bitcoin holders should be a little less than this number, but not much smaller, because after all, there are not many large trading platforms
In addition to the above two problems, [3] also gives many interesting conclusions, such as: < UL >about 55% of bitcoin can be saved without money
in places like GOx mountain, almost all deals are small ones
before May 2012, almost all large single transactions (& gt; 50000 BTC) are subsequent transactions of 90000 BTC on November 8, 2011. There are very strange patterns in this long list of transactions. For example, an entity divides 90000 BTCs into different sizes, sends them back to itself three times, and then sells them on Mt. GOx. 90000 BTCs sold are sent back to the entity through 90 different bitcoin addresses, with 1000 bitcoins per address. These operations indicate that the entity appears to be trying to hide the relationship between these transactions

the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
At exchange: a few mistakes about bitcoin, do you know
bitcoin, in a way never seen before, has an impact on the field of financial services. Whether in a bear market or a bull market, it has always been an old topic
because the underlying technology of bitcoin has been blockchain for ten years, and the technology content is high, many people do not understand it well, thus forming many misunderstandings
misconception 1: bitcoin is too expensive, a few tens of thousands of yuan, just wait and see, too expensive to buy
in most people's cognition, bitcoin can only be bought whole, which isolates those who want to invest in bitcoin. But in fact, bitcoin is divisible, and the minimum transaction unit is 0.00000001. That is to say, you can buy bitcoin for 100 or 200 yuan
in the future, with the improvement of people's acceptance and recognition of bitcoin, as well as the expansion of application, the price of bitcoin will also rise
misconception 2: the government can not regulate, which is beyond the scope of legal jurisdiction
in the early days, bitcoin was the hard currency of the underground drug market, with a transaction volume of millions of dollars each time, and there was a black market nicknamed "Silk Road"
However, at the beginning of the emergence of new technologies, it is always difficult to have written laws to regulate them, such as the beginning of computer and network applications. But in the end, these new technologies will graally come under the jurisdiction of the lawat present, bitcoin trading has been regulated in the specific legal provisions of New York State and other states in the United States. In 2014, the IRS recognized bitcoin as taxable property, and the securities and Exchange Commission has recently carried out strong supervision on it, so it is absolutely a misunderstanding that bitcoin is not subject to legal constraints. China and Japan have also begun to actively write laws and regulations related to virtual currency
misconception 3: bitcoin mining is too difficult, mining machine is a waste of resources
bitcoin mining is an energy intensive process. Because of its decentralized nature, no one knows the exact amount of electricity consumed by this process, but at any given moment, it could be billions of watts, roughly equivalent to the output of large-scale power stations such as the Hoover Dam
However, if we compare these with the management cost of currency, we can see some problems. Although the current currency does not seem to consume much energy, the cost of protection is not taken into account. For example, the security personnel employed by the bank usually just look at the customers and "waste" a lot of money and manpower, not to mention the towering buildings of the bank and the huge price paid for the safe payment system. However, if there is no security system, theft will damage the entire financial system, so this operation mode is not a wastemisconception 4: users of bitcoin are anonymous, and law enforcement agencies are traceless.
Nakamoto Tsung, the founder of bitcoin, claims that bitcoin can protect users' privacy, because most bitcoin software will create a unique pseudonym for each trader; Because of its anonymity, outsiders can not easily grasp the identity of donors
in fact, most users will leave a written record when they trade bitcoin in exchange for legal currency, and the user's identity is recorded in the transaction service with good reputation. Therefore, if the law enforcement agencies really want to trace, there are traces to follow
to sum up, bitcoin is a digital currency based on blockchain technology. As an emerging technology, it has unlimited application potential. This kind of decentralized application without government credit endorsement may achieve information transparency, security and efficiency. However, hacker attacks occur frequently. It seems that only when technology progress and supervision are in place can blockchain technology be applied globally and truly convenient to all aspects of life
No, but it seems that it is difficult to explain in a few simple sentences. Let's study this ark article together
to expose the common myth of bitcoin
bitcoin has been established for more than 11 years and is striving to be widely recognized by institutions. Although constructive criticism is healthy, ark believes that some influential financial research institutions are refuting bitcoin based on outdated information, inconsistent arguments and flawed analysis
in view of Goldman Sachs' recent position on bitcoin, ark is reconsidering the most common misunderstanding, which has affected its acceptance. We look forward to participating in the health and ecational debate on bitcoin, as well as the important role we believe bitcoin should play in a diversified portfolio
According to ark, some influential financial research institutions are refuting bitcoin based on outdated information, inconsistent arguments and flawed analysis statement: bitcoin is too volatile to serve as a store of value. Counterclaim
: the volatility of bitcoin highlights the credibility of its monetary policy
critics often point out that the volatility of bitcoin is the "value store transaction breaker". Why would anyone want to store the price of an asset in such drastic fluctuations in daily prices
we believe that these critics do not understand why bitcoin fluctuates and why its volatility may decrease
although the fluctuation of bitcoin distracts opponents from evaluating its role as a value storage tool, it actually highlights the credibility of its monetary policy. The impossible trinity is the dilemma of macroeconomic policy. As shown in the figure below, the dilemma assumes that when setting monetary targets, the decision-maker can satisfy two of the three goals instead of three, because the third goal is opposite to one of the first two goals
source: Fangzhou Investment Management Co., Ltd. in 2020, each side of the three difficulties triangle is mutually exclusive. For example, monetary authorities that choose a fixed exchange rate and allow free capital flow cannot control the growth of money supply. Similarly, the monetary authorities that choose fixed exchange rate and control currency can not accommodate the free flow of capital, and the monetary authorities that choose to accommodate the free flow of capital and control money supply can not determine the exchange rate
based on the three dilemmas, we can understand why volatility is the natural result of bitcoin monetary policy. Contrary to the modern central bank, it does not give priority to exchange rate stability. On the contrary, based on the quantitative rules of money, bitcoin limits the growth of money supply, allows the free flow of capital, and abandons the stable exchange rate. As a result, the price of bitcoin is a function of demand relative to its supply. Its volatility is not surprising
that is to say, over time, the volatility of bitcoin is decreasing, as shown below. With the increase of adoption rate, the marginal demand of bitcoin should account for a small proportion of its total network value, so as to rece the price fluctuation. If all other conditions are equal, for example, a new demand of $1 billion with a market value of $10 billion or a network value, the impact of the price of the bitcoin should be greater than a new demand of $1 billion with a network value of $100 billion. Importantly, we believe that volatility should not rule out the main reason why bitcoin is used as a store of value, mainly because it usually occurs at the same time as a sharp rise in price

for a long time, the purchasing power of bitcoin has been greatly improved. For example, since 2011, the price of bitcoin has grown at a compound rate of about 200% per year. Although significant changes have taken place in the year, since 2014, the price of bitcoin has appreciated year by year at its lowest price. It's been a good year

claims: bitcoin bubble. Counterclaim
: bitcoin is a competitor for the role of global currency
, some economists like Nouriel Roubini (Nouriel Roubini) believe that bitcoin will suddenly disappear when it is in the bubble. The line of reasoning is that bitcoin has no intrinsic value, and its appreciation depends on speculation, such as a hot potato or tulip game, and the willingness of the "bigger fool" to pay a higher price. They believe that bitcoin is not an investable asset
we believe that this statement eliminates the reason why bitcoin has accumulated value over time. Yes, bitcoin doesn't behave like a traditional investable asset[ 1] The value of equity is determined by discounting the expected cash flow. Given the high future cash flow based on growth and / or investment capital gains, the stock appreciates independently of the shareholder base
However, monetary assets such as bitcoin are unproctive, and their appreciation depends on how they effectively maintain or increase their value over time. In a sense, the value proposition is cyclical: monetary assets will appreciate with the demand of more people, and if it is an effective monetary asset, more people will evaluate it. In other words, "money is a common illusion" and "money is valuable because others think it is valuable" The claim that the value of money depends entirely on the common illusion, however, indicates that the form of money is arbitrary. In fact, according to monetary history, the most common and sustainable currencies have the quality of maintaining their demand. For example, for thousands of years, because of its scarcity, substitutability and rability, economists have regarded gold as the most successful form of moneywe think that bitcoin is usually called digital gold, which not only has many characteristics of gold, but also can improve them. Although bitcoin is rare and rable, it also has the characteristics of divisibility, verifiability, portability and transferability. A series of monetary features of bitcoin endow it with outstanding utility, which is likely to promote demand, and believes that bitcoin is suitable for the role of global digital currency even if it is not superior
we believe that as a suitable competitor for the first batch of global digital currencies, bitcoin should at least attract demand similar to gold. However, contrary to the claim that it is in a huge bubble, the net value (or market value) of bitcoin is less than 2% of gold. p>

statement: bitcoin will lose the value of fork and digital . Counterclaim
: the value of bitcoin cannot be copied only by software
in the digital field, goods are invisible and can be easily copied without destroying the original goods. Indivials can send word documents extensively by e-mail, for example, while retaining the original . Similarly, thousands of people can listen to a song simultaneously and repeatedly, which actually improves the value of the original work, especially when other songwriters imitate its unique voice
Bitcoin software is no exception. It's free and open source. Indivials can software, "create network branches" and create their own versions. However, skeptics still question how scarce bitcoin will be if it is based on open source software that can be copied indefinitelyfirst, the bifurcated bitcoin network will not create new bitcoin units, just as the expansion of Venezuela's Bolivar will not add dollars to the US monetary base. Instead, bifurcated bitcoin creates a new network with new units or coins. Although existing bitcoin holders have the right to use new coins, the forked network operates under a set of independent rules supported by a single stakeholder. Open source software does not dilute the money supply of the original network. It not only encourages cheap experiments and new networks, but also encourages new tokens and competitive markets
the scarcity of bitcoin is crucial to its network. Today, the number of bitcoins has reached 18 million, which is measured mathematically to 21 million, as shown below. Each bitcoin is linked to a wallet at a time and cannot be copied. Importantly, the only way to control user bitcoin is to have access to its associated private key
source: Fangzhou Investment Management Co., Ltd., 2020. Source: coinmetrics
so, when it forks, what makes 21 million units in bitcoin network more valuable than 21 million units in bitcoin cash (BCH) or BTC? To equate the value of bitcoin cash with the value of bitcoin is equivalent to assuming that Facebook's source code can "fork" and automatically the value of its 2.6 billion users and 50000 employees. Their value comes from the network effects of bitcoin and Facebook, not just their existence
as far as bitcoin is concerned, we believe that network effects include not only the efforts to protect the hash rate of the blockchain, but also the liquidity of bitcoin and the infrastructure supporting its adoption and use. If it is dilutive, then bifurcations will have to share bitcoin's computing power, users and liquidity. As shown below, bitcoin cash and other bifurcations do not seem to derail bitcoin's network effects

claims that bitcoin is for criminals
counterclaim: bitcoin is anti censorship
critics still accuse bitcoin of allowing criminal activities because of its early evil activities. In its early years, bitcoin financed the Silk Road, an online black market platform known for selling illegal drugs
In our opinion, criticizing bitcoin for promoting criminal activities is one of its basic value propositions: censorship. As a neutral technology, bitcoin allows anyone to trade and cannot identify "criminals". It does not rely on centralized permissions to identify participants by name or IP address, but by encrypted digital key and address to distinguish participants, thus giving bitcoin powerful censorship ability. Anyone can trade anytime, anywhere as long as the participants pay the miners. Once secured, the transaction cannot be easily reversedif criminal activities can be censored on the bitcoin network, then all activities can be censored. On the contrary, bitcoin allows anyone to exchange value globally and without permission. This is not to make it an inherent tool of crime. Phones, cars and the Internet are no less powerful than bitcoin in promoting crime
In other words, it seems that only a small part of bitcoin transactions are for illegal purposes. According to chainalysis, the number of bitcoin transactions related to illegal activities is still less than 1%, which may be a contribution to the transparency of bitcoin. Any user can view the complete history of transactions on the Internet, which shows that physical cash is a better means of illegal activitiesselected financial news

macro perspective: NPC: deploy and implement policies such as increasing the R & D expense dection proportion of manufacturing enterprises
Premier Li Keqiang presided over the executive meeting of the State Council on March 24 to deploy and implement policies such as increasing the R & D expense dection proportion of manufacturing enterprises, so as to stimulate enterprise innovation and promote instrial upgrading; It is decided to further extend the debt service extension policy and credit loan support plan for inclusive small and micro businesses to the end of this year; The Vocational Ecation Law of the people's Republic of China (Revised Draft) was passed
the meeting pointed out that in accordance with the deployment of the Party Central Committee and the State Council, enterprises should play a better role in innovation, make more use of market-oriented, fair and inclusive incentive policies, leverage enterprises and the whole society to increase R & D investment, enhance the stamina of economic development, and promote the optimization of economic structure. In recent years, the tax preferential policy of R & D expense dection has been increasing, which has effectively promoted enterprise innovation. In order to implement the relevant measures of government work report to support enterprise innovation, the meeting decided: first, from January 1, this year, the proportion of R & D expenses dection of manufacturing enterprises will be increased from 75% to 100%, which is equivalent to 2 million yuan dection from taxable income for every 1 million yuan of R & D expenses invested by enterprises. With the implementation of this policy, it is estimated that on the basis of tax cuts of more than 360 billion yuan last year, another 80 billion yuan will be cut for enterprises this year. This institutional arrangement is the most powerful policy in this year's structural tax rection. The second is to reform the accounting method of R & D expenses, allowing enterprises to choose to enjoy the preferential treatment of R & D expenses by half a year. In the first half of the year, the R & D expenses can be dected from the next year's income tax final settlement to that year's October prepayment, so that enterprises can benefit as soon as possible. At the same time, we should study the tax support policies for technology R & D service enterprises and "innovation and entrepreneurship" enterprises. The meeting called for strengthening the publicity and interpretation of policies, optimizing tax services, streamlining the audit process, improving the convenience of enterprises to enjoy policies, and doing a good job
source: China government website
comments: the implementation of policies such as increasing the proportion of R & D expenses plus dection of manufacturing enterprises deployed at the current National People's Congress is a relevant measure to implement the government work report to support enterprise innovation According to the government work report, it is necessary to "continue to implement the policy of 75% dection for enterprise R & D expenses, and increase the proportion of dection for manufacturing enterprises to 100%". The additional dection of the new deal is equivalent to a tax rection for the manufacturing instry, which means that a large amount of R & D investment of enterprises can be included in the cost many times, which is good for companies with high R & D expenses

the latest announcement on January 23, 2021 is as follows:
from January 28, 2021, the returnees are required to return home with the valid negative results of nucleic acid test for new coronavirus within 7 days. After returning home, 14 days of home health monitoring will be carried out. During the period, there will be no aggregation or mobility, and nucleic acid test will be carried out every 7 days< A novel coronavirus pneumonia prevention and control programme in rural areas in winter and spring was deployed in BR and.
take the initiative to carry out nucleic acid testing in the disease control and prevention institutions or medical institutions in the place of work. When returning home, with the valid negative certificate of nucleic acid testing within 7 days, report to the village (neighborhood) committee where you live for registration at the first time, and check the health code
the specific common problems are as follows:
① why should we strengthen the management of epidemic prevention and control for the returned workers
since winter, sporadic cases and local epidemic situation in rural areas have increased significantly, seriously affecting the local normal proction and life order. The ability of prevention and control in rural areas is weak, and it is difficult to prevent and control the epidemic situation. Especially, the number of people returning home ring the Spring Festival transportation is significantly increased, and the flow of people is increased, which will further increase the risk of epidemic transmission
in order to strictly implement the prevention and control strategy of internal rebound, it is very necessary to strengthen the management of epidemic prevention and control for returning personnel. Nucleic acid testing is an effective means to find new coronavirus infected people as soon as possible. It is required that the returning personnel should hold the negative certificate of nucleic acid testing, which can effectively rece the risk of the epidemic spreading into rural areas and ensure everyone to spend a healthy and safe spring festival
2. What groups of returnees are included in the work plan
returnees referred to in the work programme refer to those who return to rural areas from other places
it mainly includes: first, cross provincial returnees; Second, the returnees from the cities where the medium and high-risk areas are located in the province (the personnel in the medium and high-risk areas are not mobile in principle); Third, the province's import of cold chain food practitioners, port direct contact with imported goods practitioners, isolation workers, transportation workers and other key groups
3. How to obtain the negative proof of nucleic acid test before returning home
the returnees can test in any medical institution, disease control institution or third-party testing institution with nucleic acid testing qualification at the place of departure or destination, and return to rural areas with nucleic acid testing negative certificate within 7 days or health pass code "green code" containing nucleic acid testing negative information within 7 days.
both places are low-risk areas now, and you only need to hold the green code and do a good job in personal protection when you travel in the province
the joint prevention and control mechanism of the State Council made a clear statement on January 31: except for Beijing, provinces should achieve the "six noes" - forbidding people from other places to return to their hometown for the Spring Festival; Do not implement centralized and home isolation measures for returning people; No nucleic acid testing will be carried out for non key people who flow to cities across provinces in low-risk areas; Do not check the nucleic acid test certificate for non key people returning from low-risk areas in the province; No home health monitoring will be carried out for the returnees in the province; It is not allowed to extend the period of home health monitoring at will.
