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
the first time, in March last year, bitcoin soared from tens of dollars to 266 dollars overnight
for the second time, the United States held a bitcoin hearing on September 18 last year. Before the hearing, the Federal Reserve and other relevant people looked at bitcoin. Under the influence of the good news again, the price of bitcoin rose to 8000 yuan
the third time is ring this year's World Cup. Due to the influence of the world cup, the price of bitcoin once approached 6000
for the fourth time, bitcoin suddenly rose to 3000 yuan after six months of continuous downturn and hovering around 2400 for a long time. It is said that it is the entry of hot money.

Bitcoin is illegal in China
since September 4, 2017, China has expressed its opposition to the virtual currency exchange. On the market, large-scale exchanges are graally fading out of the domestic market. Some of them are going to Japan and some of them are going to Nanyang. Of course, with the release of new regulations in Hong Kong in early November, we believe that in the future, the virtual currency exchange may obtain a legal license in Hong Kong to serve local institutional investors
extended information:
bitcoin China said that the platform will stop withdrawing cash. So far, bitcoin China has closed all transaction functions. The other two bitcoin trading platforms in China, huocoin.com and okcoin, have also stopped trading all digital assets against RMB
the virtual currency represented by bitcoin has soared, attracting a large number of ordinary people without any technology and investment knowledge to enter this high-risk market
the central bank, together with many ministries and commissions, issued the announcement on preventing the financing risks of token issuance (hereinafter referred to as the announcement), which pointed out that no organization or indivial may engage in the financing activities of token issuance illegally According to the announcement, all kinds of token issuance and financing activities should be stopped immediately from the date of issue
the organizations and indivials that have completed the token issuance financing should make arrangements such as liquidation, reasonably protect the rights and interests of investors, and properly handle the 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
the China Internet Finance Association issued the "tips on preventing the risks of bitcoin and other so-called" virtual currency ", pointing out that bitcoin trading platform is a tool for money laundering, drug trafficking, smuggling, illegal fund-raising and other illegal criminal activities e to the expanding number of stakeholders and strong speculative atmosphere; There is no legal basis for the establishment of various so-called "currency" trading platforms in China
the first problem is system security:
we say that in the world of bitcoin, all information is expressed in the form of code through hash operation
then, where there is code, there must be loopholes, which give hackers an opportunity to take advantage of
as early as 2010, shortly after the emergence of bitcoin, a hacker took advantage of the vulnerability of bitcoin's core software to create hundreds of billions of bitcoins. It's like a person mastering the banknote printing machine. It's terrible. Or, hackers directly hack into our computers and steal our private keys, which will also cause us heavy losses
the second problem is that the transaction processing speed is too slow:
in the bitcoin system, there are up to seven transactions per second, which obviously can not meet the normal transaction requirements. We need to know that Alipay, Taobao and WeChat can handle hundreds of thousands or even millions of transactions every second. A deal can only be processed in 1-2 seconds. If bitcoin is used for daily money, then we will pay 1-2 yuan to handle it successfully.
the third problem is that bitcoin mining consumes too much power: Mining requires professional mining machines, which have high computing power, but consume a huge amount of power. Moreover, according to the current market, it is difficult to recover the cost of buying a mining machine for a year. Therefore, some people doubt: what is the significance of consuming so much power to maintain a system with such slow trading speed
the fourth problem is the regulatory attitude:
at present, the attitude of various countries towards bitcoin is very polarized: the supporting countries and retail stores accept bitcoin for payment, and there are also bitcoin ATMs; Countries that don't support it will crack down on it
to sum up, if bitcoin is measured by a monetary system, it must have various shortcomings. However, we can not deny the brilliance of bitcoin: bitcoin represents not only a new set of "decentralized" currency system, but also the origin of blockchain technology and a new ideology, which has far-reaching influence
from the perspective of bitcoin's own function currency:
bitcoin is the largest digital currency so far. It is an important application in the era of blockchain 1.0 and the first application of blockchain. Under the premise of decentralization, bitcoin realizes the functions of digital currency in the stages of issuance, payment and circulation, which is a new means of payment
from the perspective of bitcoin's underlying technology, blockchain:
with the increasing attention of bitcoin, blockchain, as its underlying technology, is becoming more and more well known by the public. Blockchain has graally separated from digital currency and penetrated into many commercial fields. Different instries hope to apply bitcoin Technology to our real life, Through a variety of application scenarios, let us get a better experience
from the perspective of bitcoin ideology:
it has set off a great ideological storm. The "decentralization" and consensus mechanism of bitcoin is a new ideology in the current centralized society. Throughout history, whether the Renaissance or the enlightenment, these are all ideological changes under specific historical conditions. The popularization of these new ideas and new consciousness will take a long time to be accepted by all. In terms of the influence of bitcoin:
digital currency has been accepted and recognized by some national markets, resulting in a large number of digital currency trading platforms and the emergence of a large number of counterfeit currencies. These counterfeit currencies have further evolved into a new financing mode, writing the myth of sudden wealth, which has also led to the proliferation of cheating under the banner of digital currency, such as air currency and pyramid selling currency
in short, bitcoin has outlined a grand blueprint, that is, the currency in the future will no longer depend on the release of central banks, but on the global currency unification. However, from the current situation, the blockchain 1.0 era, represented by bitcoin, only meets the basic functions of digital currency and cannot be popularized to other instries
however, in a word, bitcoin: there are shortcomings in the United States and China, and it is hard to cover up the edge.
for the sake of wealth, businessmen, programmers and civil servants have all joined bitcoin crazily. Over the years, the price of bitcoin has gone through ups and downs. Some of them are already rich, while others end up in dismay among the earliest players of bitcoin in China, there is a legendary life of getting rich overnight, as well as a tragic story of family destruction. These stories bear witness to the development history of the coin circle
in fact, in my opinion, for bitcoin, the first batch may get up early and catch up late. Why do you say that< because over the years, people who can hold bitcoin are full of faith. Most of them came into contact with each other in the past 13 years. They were sold when the price rose to more than 7000, or got off ahead of time, or plummeted after the price rose. Now it's too late. The person who holds bitcoin for a long time is the one who forgets the private key of the wallet, which means that this part of the coin is lost and will never be taken back
bitcoin plummeted. I have no experience of buying virtual currency. I advise those who want to speculate in digital currency not to enter the market in the near future, which may lead to economic losses the earliest digital currency is private digital currency. The origin of cryptocurrency is bitcoin, which appeared in 2008. Later, Ethereum appeared. Because of its anonymity and decentralization, cryptocurrency has been recognized by more and more people, and the scale of global private money market is expanding. At present, there are more than 5600 digital currencies in the private money market
