Bitcoin dispute
recently, the identity of Satoshi Nakamoto, the father of bitcoin, was accidentally exposed, which made bitcoin, which had graally faded out of the public's view, hot again. However, Craig, an Australian businessman with low-key and simple daily behavior, is still in the market; It took only five days for Craig Wright to admit that he had no courage to give up and prove that he was Nakamoto
not surprisingly, the mystery of "Nakamoto Tsung" will continue
"the twists and turns of Zhongben Cong's identity have not brought significant impact on the bitcoin market," Li Qiyuan, President of bitcoin China (BTCC), said in an interview with the first Financial Daily yesterday (May 9). As an innovative thing, bitcoin has been able to survive and grow steadily in the past few years, marking a kind of success. Liu Shengjun, executive vice president of China Europe Lujiazui Institute of international finance, is worried about the development prospect of bitcoin. "At present, no government is willing to give up its management power and accept bitcoin to replace legal tender."< On November 1, 2008, Nakamoto published a research report in a secret cryptography discussion group, in which the concept of bitcoin was first proposed. In 2009, the world's first bitcoin algorithm software appeared. In just four years after that, the price of bitcoin increased by hundreds or even thousands of times, which eclipsed other investment targets
as the creator of bitcoin, "Nakamoto Tsung" not only grasps the most core technology, but also increases people's curiosity and speculation about his real identity because of its huge wealth brought by about 1 million bitcoins (the current price of one bitcoin is about 2970 yuan)< On May 2, Wright publicly told several major overseas media that he was the so-called "Nakamoto Tsung", the founder of bitcoin, which aroused heated discussion in the market<
(the price trend of bitcoin in the past year)
Wright, 46, is a computer scientist and an entrepreneur. When he introced himself at the 2015 bitcoin investor conference, he said that he was a scholar, engaged in business research, and had a doctor of law and a master's degree in statistics
according to foreign mainstream media, Wright confirmed his identity as "Nakamoto Tsung" from a technical point of view by using the bitcoin owned by the founder of bitcoin. Wright also said publicly that it was not easy to make a decision to disclose his identity, and the reason for his clarification was his love and concern for his work, which he "hoped to eliminate the false legends and worries surrounding bitcoin"
as the Internet world continues to argue about Wright's real identity, the plot takes a major turn< On May 6, Wright suddenly published an open letter entitled "I'm sorry", saying that he "has no courage" to continue to prove his identity as "Nakamoto Tsung"
"I believed that I could end the years of hiding and hiding. However, with the events of the past week fermenting, I was going to publish the evidence that I had the initial block, but I couldn't stand it. I don't have the courage. I can't do it. " Wright said<
Wright once said in his public identity that he did not want money, nor did he want to be famous, nor did he want to be worshipped, but only wanted to be alone. Li Qiyuan told China Business Daily that if he really wanted to live his own life, why did he suddenly choose to expose his identity
obviously, the emergence of Wright has not completely ended the mystery of "Nakamoto" and investors are more concerned about the impact of "Nakamoto" on the price of bitcoin
Gong Ming, the founder of blockchain pencil, told the first financial daily that the identity of "Zhongben cong" will not have a substantial impact on the market, but is more symbolic. Unless "Nakamoto Tsung" sells a lot of bitcoin, it will not have an impact on the price of bitcoin. "From 2009 to now," Nakamoto Tsung "is not a person who has a strong desire for money and will not buy or sell bitcoin because of the high or low value of the currency."< Recently, Zug, a small Swiss town, announced that from July 1 this year, buyers will be allowed to pay for its public services with bitcoin as the payment method. Although there are still great limitations in the scope and amount of this payment method, the small progress is enough to cheer bitcoin's staunch admirers
from the beginning, virtual goods can only be purchased on the Internet, to now, bitcoin can be converted into multi-national currencies, and there are many twists and turns along the way
in February 2014, Mt. GOx, the world's largest bitcoin trading platform at that time, said that bitcoin was stolen e to large-scale hacker attacks, with a total loss of $470 million, and the platform declared bankruptcy. Affected by this, the price of bitcoin plummeted from more than $600 to $102 in just a few seconds, a drop of 83%
in January 2015, bitstamp, one of the most reliable bitcoin trading platforms in the world, was attacked by hackers, resulting in the theft of at least US $5 million of bitcoin, causing panic among some cryptocurrency holders. The openness and security of bitcoin cause instry concern. When the negative news came out, bitcoin was finally recognized by the regulatory authorities
in September 2015, the US Commodity Futures Trading Commission (CFTC) confirmed for the first time that bitcoin and other virtual currencies are defined as commodities, which means that bitcoin is classified as commodities like gold and oil, and trading behavior will comply with all commodity derivatives market rules; In October of the same year, the European Court of justice formally ruled that bitcoin and other virtual currencies in Europe should be exempt from VAT just like traditional currencies. Because according to the relevant provisions of the EU, "currencies, bank bills and coins used as legal tender" do not need to pay VAT. Bitcoin has taken a solid step towards legalization
nevertheless, the market is still worried about whether bitcoin, which reached a historical peak of more than 8000 yuan in 2013, can return to its former glory
at present, the price of bitcoin is hovering around 2900 yuan, which is much more stable than the previous ups and downs, and the trading volume of bitcoin has also dropped significantly
"I don't think bitcoin has changed from hot to cold. Compared with the sharp rise and overheating in 2013, I think it is now the normal price of bitcoin. In 2013, bitcoin rose from tens of dollars in January to thousands of dollars in less than a year, overdrawing the later increase, so it has been falling back after 2013." Gong Ming told the first financial daily
how much is bitcoin worth? It is estimated that bitcoin players, exchanges, mining machine manufacturers and even bitcoin creators can not give an accurate answer
although the value of bitcoin cannot be determined, one thing is certain that the number of bitcoins is certain. Because the "issuance" of bitcoin depends on complex calculation, it is essentially different from the "printing" mode of traditional currency issuance. The total amount of bitcoin graally increases according to the design predetermined rate, and the increase rate graally slows down, and finally reaches the limit of 21 million in 2140. The instry estimates that the total amount has reached 15.5 million
Li Qiyuan believes that the limited number of bitcoin is in sharp contrast to the inflation and the decline in the purchasing power of fiat money caused by the massive printing of money by central banks“ The goal of bitcoin is not to replace the existing currency, but to become a universal digital asset in the world and provide convenience for people's lives. "
it is generally expected that with the departure of short-term speculators, the continuous development of bitcoin related applications and the improvement of infrastructure, the digital currency represented by bitcoin will be in a benign development stage
in addition to bitcoin, there are also outstanding digital currencies such as lightcoin, Ethereum, dogcoin and Ruitai coin.
I think it is certain to give up
17 years to participate in a dinner, drink half of the wine. People in the group let me share what bitcoin is. Then a big man said: & lt; It's Nakamoto that invented bitcoin, right? How many bitcoins does he have? The first bitcoin system can only run on its own computer, so it is paid for the previous block, which is estimated to be about one million
big brother also said that this is too little, a total of 21 million. As the founder and chairman of the board, Sun Tzu should have at least 67% of the shares and absolute control, or worse, 51%. Moreover, he will separate every transaction in the future
I don't think the boss is going to stop. Pull the boss to say drink. Who knows, Nakamoto is an idiot. Mom, I think I just told another interesting story. Yes, the maximum amount of a bitcoin is more than 100000. If you think of bitcoin as a company, its market value is more than 2 trillion, ranking among the top ten in the world. If Nakamoto had given himself more marks, he would now be the first rich man in the world. Both Bezos and Bill Gates have to call dad{ RRRRR}
Yes, human beings are selfish. The world is the jungle. There are common genes in human DNA. That makes us feel the same emotions. It's one of the guarantees that we humans can help each other and live to the present
the highest price is 1 million bitcoin, worth 20 billion US dollars. Since the birth of bitcoin in 2009, there has been no bitcoin in Nakamoto's wallet address
every time I think about this, considering the struggle against humanity and ugliness, I think life is worth it. If we calm down, we can win
The search for bitcoin on the Internet has been going on all the time, and its price has been fluctuating and rising, and has broken through a number of barriers, such as $30000, $40000 and $50000. It has become the most popular investment contract in the virtual currency circle, but e to market volatility, for greater reasons, it will be cleared almost every trading day. The huge amount of money involved makes some investors completely unable to calm down. Of course, for those traders who make profits many times, they will naturally make a lot of money, and their personal wealth will be more and more. Therefore, when investing in virtual currencies (such as bitcoin), when the market fluctuates sharply, there will be some happy and sad phenomena
In addition, although the current price of bitcoin has been rising, there is still a lot of controversy in the market. Many financial institutions take a negative attitude and regard it as a speculative asset rather than a currency because of its lack of practicality. Value support, and at the same time issued a number of warnings. In addition, India is about to implement the ban on cryptocurrency, other countries are not very optimistic about the prospect of virtual cryptocurrency, some criminals use their hidden money laundering crimes, so there are many uncertainties in the future market trendthe bitcoin market is an extremely crazy market. Some people have become billionaires overnight, while others have been cut leeks. The ups and downs, joys and sorrows of the world are incisively and vividly interpreted anyone who knows about the bitcoin market should know that before, the value of bitcoin was only 1000 yuan, but it rose to 17000 yuan in 2017. With such an appreciation rate, the profits matched with it are also amazing. Bitcoin appeared in 2009. At that time, the value of bitcoin was only US $0.1. Looking at the price in 2017, there is a big difference between the two. If someone had a lot of bitcoin when it first came out, he would be one of the richest now
When the engineer became a billionaire, he began to travel around the world. In fact, he has long had the idea of traveling around the world, but e to economic reasons, it has not been realized. Now, the engineer can live freely and realize his dream of traveling around the world. In an interview with reporters, the engineer also said, although his original job is very good and can provide him with stable income, he has always dreamed of the global world and visiting friends from various countries. Now, he is living the life he wants, and by selling bitcoin, he has got hundreds of millions of assets, which is enough for him to spend his whole lifeYes , January 22 , the price of bitcoin continued to decline in the previous two days. According to the price of coindesk, the bitcoin price once fell to $28845 , 17.83% lower than the highest price of $35102 in 24 hours
as of 10:10, the price of bitcoin was about US $29918, with a decrease of 13.94% in 24 hours. The turnover of bitcoin in 24 hours was US $70.71 billion, with a market value of US $556.66 billion. This is the third consecutive day that the price of bitcoin has fallen. On January 20, the price of bitcoin fell from more than $37000 to less than $35000, and then fell below $32000 on January 21
extended data
the dispute over the price of bitcoin continues:
in the past seven days, bitcoin has experienced a roller coaster like correction, falling for three consecutive days and piercing the 10 day moving average downward. Compared with the historical high of nearly 42000 US dollars in the first ten days of this month, it has dropped to more than 10000 US dollars in just a few days
at present, the dispute over the price of bitcoin continues: those who believe that bitcoin will continue to rise believe that institutions' understanding of the digital currency is graally maturing and use it as a hedge against inflation; Opponents argue that this is just another bubble after the collapse of the bitcoin in 2017. p>
John Normand and Federico manicaldi, strategists of JPMorgan Chase, wrote in a report on Thursday that bitcoin has set the fastest price appreciation record in the history of major assets, and the current price is far higher than its mining cost, which means that the decline of bitcoin's return rate will be inevitable
With the change of global economic situation, digital currency is becoming a new currency. More and more people know that it is very easy for a bitcoin to be worth hundreds of thousands. For those with investment vision, there were not many people who owned a lot of bitcoin and became rich in the early days. Some, however, do the opposite. Although others continue to hold bitcoin, they will cash out 100000 bitcoins in advance to make a lot of money, and then they will soon stop participating in related transactions. How is he now
according to the Internet, Li Xiaolai, a former entrepreneur and English teacher, claims to be "China's richest man in money". He has a keen sense of Internet celebrity status hype and use, and he has become a lot of leek life tutor in the world of virtual currency. People finally find out, however, in fact, he is the last man to cut chives
"leek cultivation"
for investors, it is very important to understand the nature of bitcoin and other virtual currencies. Because there is no authoritative bank at the national level as guarantee, the value of bitcoin is actually a kind of existence controlled by some capital and companies. It has become a common practice for many capitals to use their own identity and status to advocate bitcoin and realize it quickly after people buy a lot of bitcoin
in order to make money, many people will use this kind of tuyere to try to speculate, but in the vast majority of cases, in the case of lack of information, ordinary people can not tell whether because of their own existence value, the investment behind may be because of the capital to promote investment opportunities
as an Internet celebrity, he claims to be "the richest man of bitcoin". In China, Li Xiaolai shows the secrets behind the capital circle of most people, which is also a disguised reminder that investors are always the capital in the eyes of leeks. As the highest level of leek, rationality and prudence are necessary
secondly, however, there is a smaller threshold for the total number of "smart": the largest possible integer that can be represented in floating-point format. Integers are not the only numbers that computers can store; To deal with decimals, computers & gt; Use a format for floating point representation. Floating point notation is essentially a binary version of scientific notation. For example, here is a value you will encounter when you study physics:
mass of the earth: 5.972 1024 kg
mass of the sun: 1.989 1030 kg
speed of light: 2.998 108 M / s
light year: 9.460 1015 m
mass of proton: 1.672 10-27 kg
Planck length: 1.616 10-35 m
we can notice that, How does scientific notation allow you to represent all of these values with reasonable accuracy, even though they vary greatly in size. Floating point notation is essentially a binary scientific notation; When you store numbers & gt; When the word is 9.625, what your computer stores is "1.001101
* 1011" (in other words, it stores 0100000000100011
& gt; This is the same thing with high-precision sequence form). In this high-precision form, the coefficient (that is, the part that is not the exponent) has 52 bits. This means high precision (more refined & gt; Double precision floating point number is enough to store up to 253 numbers, but it can't be any higher. If it exceeds 253, you have to start cutting off the numbers at the end. Bitcoin's 250.9, the total number of "smart" in the form of index, is just & gt; OK, below this maximum
if we have integers, why should we care about floating-point values? Because more high-level programming languages (such as JavaScript) do not open low-level "floating point" and "integer representation", but only provide "number" representation for programmers; Concepts
– of course, in floating-point form. If Nakamoto chose 210 million instead of 21 million at that time, bitcoin programming in many languages would be much more troublesome than it is now
note that Stefan Thomas unfortunately didn't notice this in time when he wrote bitcoinjs, so that the library used a special "big number big
number" object instead of an ordinary number to store the tutorial output value; My own bifurcated bitcoin JS (along with other improvements) uses ordinary numbers.
One of the controversial properties of bitcoin is its fixed supply, which ensures that it will not be subject to inflation. It has also become a key factor in the rapid growth of bitcoin in the past eight years. But what is the total cap of 21 million? Many people know that this is the fixed amount written by Nakamoto in the algorithm, but the reason for his design has not been clearly explained. This is the recent trend from the screenshot of the official website of coin e-commerce. You can refer to
