Why can bitcoin be used as currency
Because 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
many websites for technology players have begun to accept bitcoin transactions. For example, websites like hotcoin, coin an and okex, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin. There are specialized bitcoin third party payment companies abroad, similar to the domestic Alipay, which can provide API interface services. p>
you can use money to buy bitcoin, or you can be a miner to "mine" them, and use computers to search for 64 bit numbers. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network. If the computer can successfully create a set of numbers, it will get 12.5 bitcoins
bitcoin is decentralized. It needs to create a fixed number of bitcoins in each unit of computing time. It can get 12.5 bitcoins every 10 minutes. By 2140, there will be 21 million bitcoins in circulation. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging
extended data:
monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
According to analysts at Goldman Sachs, bitcoin can become a legal and widespread form of currency, but it is mainly possible in theory
Analysts believe that the reality is that cryptocurrency still has a very high threshold in most places. First, the government cannot track who is buying or selling bitcoin. And as we all know, the price of cryptocurrency is very vulnerable to large fluctuations. This volatility is very rare in legal tender, so bitcoin is not suitable to be a reserve currencyThe 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

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 a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.
let's talk about the birth of bitcoin. Bitcoin was designed by a man named Nakamoto in 2008. He designed a complex algorithm. If you use your computer to crack it, as a reward, bitcoin will be generated (which is also called mining). When your computer completes certain cracking tasks, a bitcoin will be created, which belongs to you. Of course, money can't be created indefinitely, otherwise it will cause unlimited inflation. So, as more and more bitcoins are created, your computer will need to do more work to create new bitcoins. Eventually, by 2040, the total number of bitcoins will be strictly controlled at 21 million
bitcoin cannot be used as ordinary currency
