Bitcoin 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
According to the latest income statement of ICO project, Neo (prototermite stock) has increased as much as 282 times since it completed ICO and went online in September last year, and quantum chain (qtum), which ranks second, has also increased nearly 100%. Such a rise makes ICO, which is very similar to the IPO in the capital market, in full swing, and spreads from the investment circle which originally belongs to the minority to the mass investors
On August 28, an insider of China Securities Regulatory Commission confirmed to reporters that the recent hot ICO has attracted the attention of the regulatory authorities and is currently preparing various materials“ At present, ICO has great risks. In the long run, it will definitely be included in the regulation. "
4 ask ICO
1, should ICO be included in the supervision
Tang Ling, CEO of Zhigui technology and general initiator of ink chain, told reporters that ICO should be included in the supervision. Under the demonstration of wealth effect, there are too many "pyramid selling currency" and "air currency" at present. Many projects can be financed before they are determined. Investors are crazy about speculating in currency, and the risk is great
Xiao SA, director of China Science and Technology Finance Law Research Association, believes that the national financial work conference emphasizes the need to strengthen the "professionalism, unity and penetration" of financial supervision, and all financial businesses should be included in the supervision. ICO should also be regulated. Financial innovation has vitality only when it is in accordance with the law, and any violation and abuse will be counterproctive
Li Lin said that since there is no supervision on the use of funds after ICO financing, the whereabouts of funds after financing have become a mystery. He suggested that regulators should pay attention to the appropriateness of investors
How should ICO be supervised Tian Ying, vice president of okcoin, believes that the first step in the supervision of ICO is to clarify the legal nature. The registration management of ICO's enterprises and the open and transparent trusteeship management of ICO's tokens should be carried out. The project sponsor, token circulation platform and the third-party propaganda organization should strengthen the inspection of the authenticity of the project, increase the risk ecation of investors, and effectively control the risk. These regulatory measures can be implemented after qualitative analysis. There are also many legal experts who suggest to refer to the financial technology sandbox regulatory system implemented in the UK and Singapore to minimize the contradiction between innovation and riskfor how to supervise, Tang Ling suggested setting up project audit and e diligence. At present, the ICO project is "self-examination and self passing meeting". Although the agent investment platform will also audit, it has not been put on record. At the same time, we should set up the fund trusteeship. In the early stage, some media exposed that indivial platforms used capital precipitation to buy financial procts, which was caused by the lack of fund custody, and it was easy for the platform to roll up money and run away. In addition, standardized management, the funds should not be allocated at one time. Many entrepreneurs haven't seen so much money and don't know how to spend it. It's easy to have problems
Xiao SA believes that the specific supervision focuses are: proct registration, information disclosure, asset custody, project authenticity and qualified investment
"proct registration is an effective way for regulators to understand and monitor high-risk financial business; Information disclosure is a routine scheme, which can make the project more transparent; Asset custody to prevent stakeholder cases; Project authenticity is the minimum requirement for ICO issuers; Qualified investment, matching the risk and investors, restricting speculative funds. " Xiao SA said
3. What are the difficulties of ICO supervisionTang Ling said that the regulatory difficulty lies in that many platforms can now achieve ICO through smart contracts, especially through Ethereum's projects, which can be raised by themselves without going through the platform. There are many private placements with high risks
According to Tian Ying, identifying the nature of ICO is a difficult point in promoting supervision. ICO is a bit like crowdfunding, but it is not exactly the same as crowdfunding. A while ago, the SEC of the United States announced the results of the investigation on the Dao token, believing that the token has the scope of securities and is under the supervision of the securities and Futures Law. This judgment is also the result of a lot of research and analysis by US regulators. Some non security tokens may expect the right to use certain procts, which does not belong to the category of securitiesshe believes that ICO is the proct of the Internet, and some ICO projects are operated globally. In the process of management, international coordination needs to be strengthened. What's more, how far should supervision go
Xiao SA said that there are differences in the instry on the nature of ICO. If we define the essence of ICO as "barter" and exchange one special virtual currency for another, it can be explained
if the ICO project directly raises "legal currency", including RMB, US dollar, euro, etc., it can be understood as "deposit" of illegally absorbing public deposits. Once it meets the requirements of the crime of illegally absorbing public deposits in article 176 of the criminal law, it may constitute a crime
Xiao SA believes that if the ICO project has a dividend clause, it has an equity mark; if the project has a repurchase clause, it has the suspicion of "capital preservation and interest preservation". It is similar to financial procts, and it is actually an illegal operation to issue financial procts without a license. In judicial practice, if illegal business is difficult to define, then the above behavior is likely to be identified as pyramid selling. Many ICO projects in the promotion process, there are promotional incentives, such as "pull an investor back token."
4. The impact of regulation on ICO
Xia Hu, CEO of Weiyou Yuanjie, told the Beijing news that regulators should regulate the development of ICO, especially the establishment of a "qualified investor system", because many ordinary investors do not have the ability to bear high risks and should not participate in such high-risk projects. If there is no qualified investor system, it is easy to cause social problems
as for the regulatory impact, Tian Ying said that in the short run, it will impact the current market, and in the long run, it will be concive to the sustainable and healthy development of the entire digital asset instry, so as to truly make the market healthy first and then efficient. On the other hand, supervision will also enable high-quality projects to present their value
according to a research report of Huachuang securities, the innovation trend of ICO is worthy of attention. In the long run, with its growing influence, it is necessary to accept supervision to promote the healthy and orderly development of the instry. ICO platforms or projects with strong strength are expected to take the lead in embracing regulation, balancing innovation attributes and potential risks, and become the beneficiaries of ICO's future development
according to Caixin, the relevant regulatory authorities will take action against ICO. Whether to ban the program is under discussion, the central bank, the CSRC are involved. The legal basis for this action comes from the measures for banning illegal financial institutions and illegal financial business activities promulgated in 1998
the reporter learned from a person in the instry that many departments including the financial market department of the central bank have stepped up their research on ICO, but there are still some related problems to be solved
according to a number of instry insiders, on August 18, the central bank, China Securities Regulatory Commission and China Banking Regulatory Commission organized a special ICO forum, which was interpreted as a "landmark event" in the instry, and it was only a matter of time before it was brought into regulation< On July 25 this year, the securities and Exchange Commission (SEC) issued a report on the Dao, which determined that its token was securities. At the same time, it emphasized that any act of buying or selling securities in the United States, whether it was real currency purchase or token distributed with blockchain technology, must comply with the securities law of the United States
according to the definition of financial market division on the official website of the central bank, its main responsibilities include drawing up the development plan of financial market, coordinating the development of financial market, and promoting the innovation of financial procts; In addition, the Bureau of currency, gold and silver is responsible for drafting the relevant measures for currency issuance and gold management, organizing the implementation and undertaking the work of RMB management and anti-counterfeiting currency< According to the regulatory practice of the US Securities Regulatory Commission, ICO is defined as a securities issue. Therefore, if China draws lessons from it, it should also be supervised by the CSRC. However, in China, the digital currency is supervised by the central bank. Therefore, it is the central bank and the CSRC that jointly study and decide who will supervise the digital currency< Since the first half of this year, the number of domestic ICO projects funded by virtual currency has increased explosively, which has aroused controversy over whether ICO is illegal in raising funds
according to the report released by the national Internet financial security technology expert committee, since 2017, the cumulative financing scale of ICO projects completed through various platforms has reached 63523.64btc, 852753.36eth and some RMB and other virtual currencies. Based on the zero point price on July 19, 2017, it is equivalent to RMB 2.616 billion in total. The total number of participants reached 105000
on August 24, the CBRC made regulations on virtual currency financing for the first time. The CBRC drafted the "Regulations on the disposal of illegal fund raising (Draft for comments)" (hereinafter referred to as the draft for comments) and pointed out that the illegal fund raising administrative investigation should be carried out in the name of virtual currency without legal permission or in violation of the relevant provisions of the state. The participants of illegal fund-raising shall bear the losses caused by their participation in illegal fund-raising
it is reported that Huo Xuewen, director of the Beijing Municipal Bureau of financial work, once pointed out at a closed door meeting that all activities of "managing other people's money" should be included in the supervision
Wu Xiaoling, deputy director of Finance and Economics Committee of the Standing Committee of the National People's Congress and chairman and President of Wukou School of finance of Tsinghua University, also publicly pointed out a few days ago that internationally, ICO has been regulated as a kind of securities in the United States. The people's Bank of China has also made a corresponding statement to bitcoin (pointing out that bitcoin does not have monetary attributes), and further regulatory measures are expected
a blockchain practitioner said that "blocking is better than sparing". Supervision is expected, but if it is totally negated, some enterprises will inevitably move ICO abroad<
