Norway bitcoin
The number of bitcoin is too small to circulate on a large scale in society. Moreover, its existence is not guaranteed by the national credit, but based on the trust between bitcoin players, so the credit of this "currency" is relatively low
moreover, the number of bitcoin is small, and it is too concentrated in the hands of several big players, resulting in its price is very unstable. This is basically not money. Because as a general currency, an important prerequisite is price stability, otherwise the economic order will collapse
bitcoin has no value base; The price fluctuates sharply; There are three basic reasons why bitcoin can't become the world currency e to the lack of support from monetary authorities
can bitcoin become a real currency? http://www.financialnews.com.cn/yw/pl/201401/t20140107_ 47595. HTML
since the birth of the first bitcoin seven years ago, bitcoin has been developing rapidly and caused a lot of controversy. The discussion focuses on how to define bitcoin, whether it can become a currency and even become an international currency in the future
in 2013, bitcoin was very popular in China, not only the price soared, but also was evaluated as "a big challenge to the current monetary system" by some analysts. In early December 2013, the people's Bank of China, together with five ministries and commissions, issued the notice on preventing bitcoin risks, pointing out that bitcoin is a specific virtual commodity, not a real currency. Then, bitcoin prices fell
at the beginning of the new year, on January 4, the National Bank of Malaysia announced on its website that it would not recognize bitcoin as a legal currency, and urged the public to be vigilant against its risks. In fact, since the second half of 2013, South Korea, Thailand, Indonesia, Norway and other countries have successively made their stand against bitcoin trading activities, and they do not recognize bitcoin as a currency in the market
At the same time, it is reported that in January this year, the world's first bitcoin atmrobocoin entered the Hong Kong and Taiwan markets. Companies also plan to launch bitcoin ATMs in more parts of Europe, Canada and the United Stateson the one hand, the relevant regulatory authorities have "made their stand clear"; on the other hand, the global layout of bitcoin has been advancing rapidly. How to determine the nature of bitcoin and its future development momentum have once again attracted the attention of all parties
Sheng Songcheng, director general of the survey and Statistics Department of the people's Bank of China, published an article entitled "virtual currency is not money in essence -- take bitcoin as an example" in his own name, emphasizing that virtual currency represented by bitcoin is not money in essence and it is difficult to become money
he believes that bitcoin lacks national credit support and is difficult to perform the function of commodity exchange medium as the base currency. Modern credit currency (paper money) represents national credit, and actually represents the proction and transaction of commodities in the whole society. As long as the national machine works normally, the coercive force of national laws can give the public trust in the standard currency. Bitcoin has no value itself, no national credit support, and no guarantee of the whole society's commodity proction and trade, so it does not have the value basis of money. In addition, bitcoin has no legal compensation and compulsion, and its circulation range is limited and unstable. Bitcoin has strong substitutability, so it is difficult to be a general equivalent
Secondly, the number and scale of bitcoin have set an upper limit, which is difficult to meet the needs of modern economic development. He believes that there is a contradiction between the limited quantity of bitcoin and the expanding social proction and commodity circulation. If bitcoin becomes the standard currency, it will inevitably lead to deflation and inhibit economic development. The limitation of quantity also makes bitcoin's function as a means of circulation and payment greatly reced, which makes it easier to become a speculative object rather than a medium of exchange Thirdly, bitcoin lacks a central regulation mechanism, which is not compatible with the modern credit currency system. Sheng Songcheng believes that bitcoin does not have a centralized issuer, so it is easy to be over hyped, resulting in excessive price fluctuations, and can not become a pricing currency and circulation means, so it needs to be converted into bitcoin to pay; Bitcoin is also not controlled by the monetary authorities, so it is difficult to play the role of economic adjustment meansat the end of the article, Sheng Songcheng also made it clear that money is inseparable from economic operation and economic development, and is not a pure proct of technology. As long as there is no fundamental change in the form of modern economic and social organizations, the monetary system based on national credit will exist, and bitcoin and other virtual currencies will not become the standard currency of a country, and thus not the real currency, "but the Utopia of technology supremacy and absolute liberalism"
As for the prosperity and significance of bitcoin, Sheng Songcheng explained, "the emergence of bitcoin reflects people's worries about inflation under the condition of credit currency in a sense. Central banks should strengthen liquidity management, reasonably regulate money supply, keep prices basically stable, and promote stable economic and social development. "ring the writing period, our reporter contacted Sheng Songcheng again on issues related to bitcoin. He stressed again in the interview: "bitcoin is not the real currency, the real currency can only be the standard currency."
Sheng Songcheng said, "from the perspective of the history of monetary theory, bitcoin is not new. Its essence is the privatization of currency issuance or the non nationalization of currency. Hayek, a famous Austrian economist and Nobel laureate, put forward a proposal many years ago, and Friedman, a famous American economist, also made a similar proposal. However, their opinions are only a theoretical analysis tool, which is difficult to operate in real economic life, and the modern economy is increasingly inseparable from the country's macro-control. This financial crisis and its response is a good proof. Money is one of the main means of national macro-control and the basis of modern state and government. How can it be privatized? So I use the word "Utopia."“ In my opinion, technology can not replace the national attribute. Any digital currency can only be the realization form of standard currency. Therefore, electronic money will develop, and virtual money is utopia. " Sheng Songcheng said, "as long as there is a modern state, virtual currency will not be a currency. Many people ignore the national and social attributes behind money and think that money is just a natural entity. "as for the future development prospects of bitcoin, a commercial bank analyst interviewed said: "bitcoin trading, as a commodity trading behavior on the Internet, ordinary people have the freedom to participate in it at their own risk, and there is still a lot of room for development in this aspect. At present, in view of the fact that bitcoin has not had any impact on the monetary policy of central banks, and from the perspective of issuing technology, it seems to have enlightenment, so many central banks hold a wait-and-see attitude towards it. "
but as for whether bitcoin can play the role of currency in the future, or even international currency, the analyst said that it is "not optimistic". He said, "even if some countries want to use bitcoin as the world settlement currency, but it is in private hands, and the price fluctuates violently, can it become an international currency? Moreover, the important premise for it to become an international currency is that the authorities of all countries recognize its monetary nature, which itself is a difficult problem. "
Sheng Songcheng also said, "bitcoin does not have a value base; The price fluctuates sharply; There are three basic reasons why bitcoin can't become a world currency without the support of national monetary authorities. "Bitcoin is one of the most popular virtual currencies, which is very popular on the Internet
recently, according to the bitcoin power consumption index released by Cambridge researchers, if bitcoin is regarded as a country, it will rank among the top 30 countries with the largest power consumption in the world. The annual power consumption of bitcoin mining is about 121.36 terawatt hours (TWH, 1 terawatt hour is 1 billion kwh){ RRRRR}
recently, Bill Gates made it clear that he is not a fan of bitcoin
Bill Gates said: & lt; Bitcoin consumes more power per transaction than any other way known to mankind, so it's definitely a very important climate issue. But if it uses green power, it may not be a problem in the end
I don't think these topics are deeply relevant, although you may label me as a bitcoin skeptic
in other words, instead of investing in bitcoin, I used the money to buy malaria vaccines. I invest in companies that make real procts. But if other people invest in bitcoin and make money, I'll congratulate them& rdquo;
the media's hype about bitcoin has made more than one newspaper sneer: "at present, journalists recognize bitcoin more than investors as a reliable way to store wealth." Government departments around the world are also paying attention to bitcoin. Although the Chinese and American governments have not banned it, they do not encourage people to participate in it. Here we focus on two questions: why is bitcoin so important? Why doesn't the government like bitcoin
bitcoin is a virtual payment system, which is not controlled or governed by any central government or private institutions. Unlike Alipay or Paypal, the system has its own monetary unit (bitcoin) instead of Renminbi, US dollars or other legal tender. Strictly speaking, bitcoin has no physical form. Instead, it trades over the Internet, and users store their bitcoin in their wallets. The bank account books record the depositors' deposits and withdrawals. The public can not see these records, but it is legal for the government to ask to review these records. The account book of bitcoin is called "block chain". In theory, it is a public document (anyone can download a ), but the participants of bitcoin system can easily hide their identity, because bitcoin is sent to the address randomly generated by electronic money package, which is composed of letters and numbers. In other words, I can provide a new address for each transaction. So even if people can figure out how much bitcoin they can get, they won't know if I have bitcoin
Where can I get bitcoin? One way is through "mining.". This method is by no means easy, and the computing power required for "mining" is now more than most people can afford (according to the design of bitcoin system, it will be increasingly difficult to find bitcoin). I know it's too simple to say that. The fact is that bitcoin's revenue and expenditure books are jointly maintained by "miners" all over the world. Most of the "mining" groups (more than 60000 users) that "miners" participate in spend a lot of time and power, and some of them can get bitcoin. For the majority of non professionals, it is much easier to buy bitcoin online on the bitcoin "exchange" with regular currency. Until recently, Japan's Mt. GOx was the world's largest bitcoin "exchange.". In China, bitcoin "exchange" BTC China has the longest history
I'm not surprised that China has quickly become a major bitcoin market because bitcoin has performed so well as a private trading channel. It is estimated that in 2013, the trading volume of bitcoin in China (including Hong Kong) accounted for more than half of the global trading volume, and more than 100000 bitcoins were traded in "bitcoin China" every day. People's interest in bitcoin has increased greatly, especially in China, which has led to a significant increase in the value of bitcoin, from about $0.08 in June 2010 to $1124.76 in November 2013. This led to reports that a Norwegian man bought 5000 bitcoins for $26.60 in 2009 and sold them for $886000 in 2013
unfortunately, those who bought at the peak have found that their bitcoin has almost halved in value - the current price of bitcoin is less than $600. What's wrong
for some investors, it is a problem that bitcoin has no physical form. For example, the Norwegian man mentioned above forgot his e-wallet password and had to take great pains to delete and rebuild it. Mt. GOx is much larger. It stopped trading on February 25, 2014, and then filed for bankruptcy protection in Japan and the United States because it lost about 550000 bitcoins, which were worth $473 million at that time, accounting for 7% of all bitcoins in circulation. Attorneys for Mt. GOx said in court that the reason for the loss of the bitcoin may be that "there is an algorithm defect in the bitcoin software, and someone has used this defect to invade the bitcoin network.". Investors usually stay away from such risks that they cannot understand
however, the bigger problem with bitcoin is that the Chinese and US governments are not friendly to bitcoin. In December 2013, the people's Bank of China banned financial institutions from engaging in bitcoin trading, saying that bitcoin is not a "real" currency. The bank made it clear that investors were free to participate in bitcoin trading, but at their own risk. Analysts pointed out that the Chinese government is worried that bitcoin trading by financial institutions will threaten the government's control over the financial instry, especially in terms of money supply and cross-border money flows. Before too many parts of the economy become "invisible" and untraceable, the Chinese government must act< Almost at the same time, U.S. Department of Homeland Security agents detained more than $5.1 million of bitcoin in Mt. GOx's account. They said the money came from a criminal network called silk road. In January 2014, a director of MT GOx was charged with money laundering. However, the U.S. government did not declare bitcoin illegal. Instead, after explaining the tax law, it used an unconventional means to punish users of bitcoin. In March 2014, for example, the Internal Revenue Service announced that bitcoin was an asset, not a currency. This has a significant impact. For example, if an American taxpayer buys $500 of bitcoin and then uses them to buy $1000 of goods e to the rising market price of bitcoin, he has to pay tax for his income. If the taxpayer purchases foreign currency, he does not need to pay tax when the foreign currency appreciates against the US dollar. In addition, bitcoin miners must declare the value of bitcoins by the date they were discovered, not by the time they were spent. In other words, bitcoin related taxes need to be paid immediately, even if the "miner" intends to keep these bitcoins for a few years. Recently, the U.S. government announced that it would transfer the bitcoin detained from "Silk Road", but asked the buyer to show his identity, which would inevitably weaken people's desire to buy and rece the transfer price of these bitcoins
since December 2013, China's official attitude towards bitcoin has not changed. However, the Chinese government does not allow domestic banks to do business with bitcoin "exchanges", especially in transferring RMB deposits from personal accounts to "bitcoin China". On April 28, 2014, bitcoin China said on its microblog that its user account had voluntarily stopped accepting RMB deposits. Since then, China has not encouraged bitcoin "exchanges" to allow users to withdraw Renminbi from their accounts. The future of bitcoin in China is not good, only Hong Kong may be an exception; At the same time, there are bitcoin ATMs in Hong Kong
but as far as the investment risk of bitcoin is concerned, the government's view may be reasonable. Recently, it has been reported that a "mining" group has controlled more than half of the bitcoin computing power, which may enable the group to veto bitcoin transactions verified by other "miners", or reuse the same batch of bitcoin without fear of being questioned. For most people, these problems can be too complex to solve. However, in mid June, Peter Chen, the main developer and advocate of bitcoin, made a breakthrough; Peter Todd, who sold half of his bitcoin, said: "I've learned that the factors that make bitcoin motivating are flawed, for a number of reasons. To say the least, even if only a few of the main reasons are taken into account, it will make people worried when a mining group controls 50% of its computing power. "
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
digital currency is just a concept, and large-scale payment is still far away. Other similar digital currencies include Wright coin, Ruitai coin, dog coin and so on.
mining methods
to mine bitcoin, you can download special bitcoin computing tools, then register various cooperative websites, and fill the registered user name and password into the calculation program, Click again to start the operation
after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to algorithms. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving riddles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a group of numbers, then they will get 25 bitcoins
e to the decentralized programming of bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes
the world's first "bitcoin ATM" was opened in Vancouver, Canada on October 29, 2013. It handled the exchange of Canadian dollar and bitcoin, and quickly welcomed people queuing for business.
