Is there a black virtual currency

3. As a typical representative of virtual currency, bitcoin's fall has directly or indirectly affected related instries. The news of players' wealth shrinking and mining machinery selling by Jin emerge one after another. As investors become cautious about virtual currency investment, the market is in a downturn. Facing the sluggish market, players can not see the hope of investment, so it is inevitable that virtual currency has no future. However, there are also players in low-key bottom hunting, that bitcoin led virtual currency, has great investment value< br />
The essential value of any kind of currency is that it can be used as the value scale to measure other things and has stability. The virtual currency here is not game currency, but a digital cryptocurrency like bitcoin. The bottom layer uses blockchain technology, which has the characteristics of decentralization, information tampering and anonymity. At present, cryptocurrency headed by bitcoin can not bear the property of currency. It is not fair to conclude that there is no value

a consensus has been reached in the currency circle by default, that is, bitcoin is similar to diamonds in the real world. The value of diamonds is given by businessmen, and it has been agreed that diamonds can symbolize love and have practical properties. Mining diamonds and gold also need to consume a lot of costs, but it is because a lot of costs are consumed that the constant intrinsic value of diamonds and gold can be ensured. The resources that can be obtained casually are prone to inflation< br />
The fall in 2018 makes investors return to rationality, which is actually concive to the standardized development of the currency circle. Now, regardless of the practical value of digital currency, this capital harvest makes investors further understand the importance of risk management. Money circle and Internet Finance allow investors to see that they are profitable, so they don't have to think about investing in it. It is ultimately their own loss. Whether this bear market can make investors understand the essence of money circle is still unknown. However, the future development of the coin circle still needs government regulation, as well as the regular operation of platforms and projects. Of course, only with the support of capital can the coin circle develop healthily and systematically. Therefore, capital outflow is the biggest reason for bitcoin's sharp decline.

4. In addition to bitcoin, there are many other virtual currencies in the virtual world< Liteoin (LTC) was released on October 7, 2011, and is currently the most valuable counterfeit currency, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million

this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)

compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being

the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners

ppcoin

ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age

ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million

ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity

ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<

ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency

terracoin

terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years

however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency

namecoin

namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011

namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time

this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name

in addition, Q currency, Shanda currency, starting point currency and various online game currencies are also virtual currencies.

5. Formal virtual currency trading website should have the following conditions:
1. The website belongs to the company operation, and the company's information is open and transparent
2. The website has been registered with the Ministry of instry and information technology, requiring users to carry out real name authentication
3. The platform is a third-party trading platform, not created by the operation team of virtual currency
well known virtual currency trading platforms include bitcoin China trading platform, Fuyuan Trading platform, biter, bitera, etc.

6. There must be risks. Theoretically speaking, if the existence of network currency affects the demand for the central bank's liabilities, and then interferes with the central bank's open market operation, it will have an impact on a country's monetary policy and price stability. However, from a practical point of view, the premise of network currency affecting price stability includes the following three aspects:

(1) from the analysis of the impact on the amount of money, although it is difficult to analyze the extent to which the network currency scheme creates money in the case of lack of information

however, most of the network currency systems operate in the prepaid mode, that is, issuing network currency when the real currency is exchanged in and withdrawing the currency when the real currency is exchanged out, which has limited impact. In the famous network currency scheme, the money supply is stable and the supply is small, but we still need to be vigilant whether it can ensure that the money supply will maintain a stable level in the long run, and the impact of the change of exchange rate between network currency and real currency.

7.

China does not have the first legal virtual currency. At the end of 2013, the central bank and other five ministries and commissions issued the bitcoin risk notice, which clearly defined bitcoin as a special Internet commodity, and the public can buy and sell it freely on the premise of taking their own risks

other digital confidential currencies are also suitable, such as Laite coin, the ancestor of Shanzhai coin, Fuyuan coin for business points in jewelry instry, dog coin for small reward, etc. But although virtual currency exists legally in our country, it is illegal to cheat under the guise of virtual currency

extended data

as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers

fraud

the private transactions of online virtual currency have realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints

in addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players. Take Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>

impact system

in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies

if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation

network problems

in addition to direct cash, virtual currency can also be purchased by SMS, internet transfer and fixed telephone recharge. These ways of purchase not only provide convenience for users, but also have many risks

such as embezzlement of telephone recharge and purchase by minors. In addition, virtual currency does not have the anti-counterfeiting technology of real currency. Computer hackers may use its security loopholes to proce counterfeit currency. Relevant personnel of the State Administration for Instry and Commerce said that virtual currency transaction is a business behavior derived from the Internet era, and there are no clear legal provisions to regulate it, and there are no items related to virtual goods transaction in the scope of instrial and commercial registration

but when the virtual property transaction graally employs people, places are fixed, transaction profits are clear, and has the nature of operation, it may involve market order and tax issues. Even game operators have no ability to control. There are a large number of "counterfeit banknote makers" in the network. Take the winger who is mainly engaged in chess and card online games as an example, the purchasing power of his online currency has shrunk by nearly 40% in one year. Many people point out that such inflation will only damage netizens and make them lose confidence in the Internet
