Cross border payment and bitcoin
The emergence of bitcoin is based on a set of "payment system", and its value was first born because of the choice of "forced and helpless". In the later stage, bitcoin develops in the direction of digital assets and digital gold. In addition, there is a blind area of legal supervision, which gives opportunities to some lawless elements and people and institutions who like to speculate, In addition, some people dream of becoming rich overnight, which sets off a prosperous currency circle. As the world's first digital currency, bitcoin's value has soared tens of thousands of times
After the birth of bitcoin, people didn't understand it at first, but with the development of technology, many people began to preach and preach its value when they knew how to use it, and it was in line with the needs of some people and institutions, With the participation of capital and institutions, it has been pushed to a new height. Combined with the rise and fall of the price of bitcoin in the past five years, almost every big fall has been caused by frequent cutting of leeks. Due to the lack of supervision and extremely serious privatization, many people have not made a fortune overnight through the coin circle, but lost everythingBitcoin is a kind of electronic currency / network virtual currency
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
extended data:
currency features:
1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no 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
advantages of bitcoin:
1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2, anonymity, tax exemption and supervision free
3, robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
4, borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
5, Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency
but these counterfeit currencies are very fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency
many counterfeit coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
the weakness of bitcoin
1, the fragility of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
2, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
3, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading
4, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control
but the public doesn't understand, and many people can't even distinguish between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless
1. The nature of the two currencies is different: bitcoin is an encrypted digital currency, and Morgan is a typical MLM currency
(1) 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 (2) Morgan is a kind of typical MLM currency, they often promise high income, the information of the founding operation team is not open, and they have the background of international large companies, so they put forward a set of seemingly reasonable economic theory
extension data: the harm of
network currency: the extensive application of
1 and virtual currency is also accelerating the rampant network robbers.
(1) in December 2006, the Shenzhen Public Security Bureau announced that it had cracked the country's largest theft network virtual property case, and 11 suspect was arrested. The gang used trojan virus to illegally steal virtual property such as tens of thousands of QQ numbers and QQ coins, and sold stolen goods on the network, making a profit of more than 700000 yuan
(2) in this case, the virtual currency Q was used as the standard of conviction and sentencing, and the police's arrest of illegal elements on suspicion of theft is a special case. The reason is that Tencent has filed with the Guangdong Provincial Price Bureau, and one q is equivalent to 1 yuan
(3) online currency is used more and more widely, for example, it can be used to buy anti-virus software online, vote for super girl, and some websites even use online currency to pay the moderator
2. Outside the business system, because indivial virtual currency has become the "equivalent" of RMB, or even "online RMB", which shows the role of "network hard currency", the illegal gains of illegal gambling can be cashed into RMB, which further promotes online gambling
is different from Alipay, WeChat and other electronic payment. Digital currency is a brand new digital credit currency which is different from traditional credit currency. On the morning of September 9, Zhou Xiaochuan, President of the people's Bank of China, Yi Gang, vice president of the people's Bank of China, and pan Gongsheng, vice president and director of the State Administration of foreign exchange, answered questions from Chinese and foreign journalists on issues related to "financial reform and development.". In response to a question about digital currency, President Zhou Xiaochuan said that bitcoin and other virtual currencies have not been recognized as retail payment instruments, and the central bank does not accept or recognize relevant services at present. At the same time, he also pointed out that the central bank is cooperating with the market to develop digital currency
At the same time, Zhou Xiaochuan also pointed out that digital currency may have some unpredictable effects on financial stability and monetary policy transmission. Therefore, it needs dynamic regulatory measures. Jin Yu, director of the Department of economics, School of economics, Shanghai University of Finance and economics, once commented that "virtual currency" may not only hide the grey transaction or even the black transaction, but also cause all kinds of risks, "crowd out" the real financial innovation, which is not concive to the sustainable and healthy development of Internet financeWhy is the Internet era coming to an end and the blockchain era coming
Once the
blockchain develops, it will burst out more innovation. As the first proct of blockchain, bitcoin has proced many innovations since its birth. For example, small cross-border payment, recording transfer transactions between currencies, recording various stocks, registering housing property rights, recording program codes, etc.
the steam age liberates social proctivity, the electrical age enlivens social cooperation ability, the Internet age connects the world, and the blockchain era will let us truly realize freedom
