1、 Different definitions:

1. virtual currency:

virtual currency refers to non real currency

digital currency:

digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

3. Cryptocurrency:

cryptocurrency is a kind of transaction medium that uses cryptography principles to ensure transaction security and control the creation of transaction units

4. Token (token):

a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English

Second, the characteristics are different:

1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency

2. Digital currency:

is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities

4. Token (token):

usually needs to be exchanged for money, used in shops, playgrounds, mass transportation and other places, as a voucher to use services and exchange goods

extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

2. 1. Although network virtual currency can not be completely equivalent to money and other traditional property, in specific occasions, the perpetrator can achieve the criminal purpose of illegally obtaining other people's property through the possession of virtual currency. Therefore, the fraud of virtual currency may also endanger the property safety of citizens, legal persons and other organizations, which has considerable social harmfulness and should also be punished as a crime
2, if the public security organs suspect the criminal detention, the procuratorate can not approve the arrest, they should apply for l pending trial. Bail pending trial also goes through the court
the seventy-seventh provision of the criminal procere law stipulates that the people's court, the people's Procuratorate and the public security organ shall not exceed twelve months for the suspect and defendant to be l, and the longest residence shall not exceed six months.
ring the period of l pending trial and residential surveillance, the investigation, prosecution and trial of the case shall not be interrupted. If it is found that criminal responsibility should not be investigated or the term of l pending trial or residential surveillance has expired, the l pending trial or residential surveillance shall be lifted in time. In case of cancellation of l pending trial or residential surveillance, the person who has been led pending trial or residential surveillance and the relevant units shall be informed in time.

Virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies

virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software

real risk

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 transaction of online virtual currency has 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

Taking 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

reference: network virtual currency

4. It's unreliable. Virtual currency has no real value. It's not a real currency, and there is no credit endorsement for it. It's not like that RMB and US dollar all have credit endorsement from big country government. This kind of virtual currency is greatly affected by human manipulation, policy risks, and the government does not allow transactions

5. 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.

6. Virtual currency can only be traded online, it needs to be on a special website

7. No, apple system charges a 30% service fee for virtual currency transactions, so many companies don't use it.

8. The value embodiment of blockchain data
when many people mention big data, they will mention such a view: data is value. From a macro point of view, there is no problem with this argument. However, if we go back to the argument process of this point, we will find some interesting things
information itself does not have the ability of direct cash flow, and the value of information is reflected in the use. When people demonstrate the value of big data, the logic is: "if enterprises want to remain invincible in the competition, they need to make continuous efforts in data collection and processing, collect more data and better analyze data, and innovate business models and make accurate business decisions with more information support."

from this demonstration process, we can see that in essence "data is value" is derived from "information asymmetry". From many examples in the stock market, we can see that if a listed company has serious problems ring the closing period, and this information is known to all, after the opening of the market, the company's stock will directly plummet
people who have this information have not realized data realization. However, if only a few people know this information, it will have strong liquidity
economics has an important premise: "scarcity leads to exchange, and exchange leads to value", which also applies to data value. If data is scarce and meaningful, it can often be exchanged to generate value
the data on the blockchain is open and transparent, so the data on the blockchain is not scarce. If we look at the data on the blockchain from the logic of big data, then the value of these data is very low. This is because the original intention of blockchain is never to try to benefit indivial, but to benefit all participants as a whole
the data on the blockchain is open, transparent and tamperable, and can be used by any participant in the blockchain. It is precisely because of these characteristics that "no center in the blockchain can control the system, and once the data is generated, it cannot be changed. This creates a strong trust, so people often say that blockchain is a trust creating machine. "
to demonstrate the value of the data on the blockchain, the correct logic is: "because the data on the blockchain reces the transaction cost of the whole instry, this is the embodiment of the value of the data on the blockchain."
therefore, we say that the value of data on the blockchain is more reflected as a use value than an exchange value. Things with high use value and low exchange value are usually basic materials for human survival. In many theories of economics, "water" and "air" are taken as examples to demonstrate the relationship between exchange value and use value. Based on this analogy, we can conclude that blockchain is also an underlying infrastructure
in fact, blockchain is very similar to the Internet. As the infrastructure at the bottom of the information society, the Internet carries a huge amount of wealth and value, but people seldom pay attention to the data on the Internet core router and core network. Blockchain technology will be the underlying infrastructure of the future credit society and value Internet. People will pay more attention to the business model and specific application of blockchain. The form and specific content of the underlying data of blockchain will no longer be valued by most people, and the underlying technology will most likely tend to be unified.

9. Deceptive, "blockchain", "quantitative", "arbitrage" these three words you understand? If you don't understand it, it's cheating you. If you understand it all, it's the way of nature. It's a fraud
