1.

Some virtual currencies are illegal in China. Chinese laws prohibit virtual currencies. The only legal currency in China is RMB. Since the people's Republic of China issued RMB, it has lasted 71 years. With the development of economic construction and the needs of people's life, it has graally improved and improved. So far, it has issued five sets of RMB, forming a multi variety and multi series monetary system of paper money and metal money, ordinary commemorative money and precious metal commemorative money

except for 1,2,5 fen coins, the first, second and third sets of RMB have been withdrawn from circulation, and the fourth set of RMB has been suspended from circulation since May 1, 2018 (except 1 jiao, 5 jiao notes and 5 jiao, 1 yuan coins). The current circulation of RMB is mainly the fifth set of RMB issued in 1999

< H2 > extended information

the people's Bank of China is scheled to issue the fifth set of RMB 50 yuan, 20 yuan, 10 yuan, 1 yuan banknotes and 1 yuan, 5 jiao, 1 jiao coins of the 2019 edition from August 30, 2019. The fifth set of RMB inherits the traditional experience of China's printing technology and draws lessons from the advanced technology of foreign banknote design, which has greatly improved its anti-counterfeiting performance and currency processing modernization

Chairman Mao Zedong's head portrait in the early days of the founding of the people's Republic of China is used on the front of each denomination currency, the famous Chinese flower pattern is used on the bottom, and the main scenery pattern on the back fully shows China's long history and magnificent mountains and rivers, and carries forward China's great national culture by selecting representative patterns with national characteristics

2. 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.
3. For example, the game currency used in online games, in fact, is recharged with real currency, or the game reward (game equipment or level) you get for spending a lot of time and energy in the game. In a sense, it condenses your labor and forms the income of labor, so when others violate your virtual currency in the game, That is, it constitutes a crime
in the form of game fraud, game account theft, etc
4. At present, the more reliable are bitcoin, Wright coin, Fuyuan coin, doggy coin, reborn coin and so on

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. Old brand cryptocurrency, the ancestor of cryptocurrency<

Fuyuan coin, a new generation of cryptocurrency for application business circle, is a decentralized cryptocurrency, which is generated in the proct operation and circulation of member enterprises of global Jewelry Instry Association (similar to business points). Users can obtain certain Fuyuan coin when purchasing jewelry procts of member enterprises, and Fuyuan coin can be used for shopping in member cooperative businesses, You can also trade freely on the Fuyuan currency trading platform.
5.

Japan is also the first country in the world to legislate on virtual currency. Just in April last year, Japan's "change of capital payment law" was formally established. Virtual currency is defined as having the function of currency and can be used for monetary payment. Moreover, some time ago, the tycoons of the domestic currency circle also went to Japan one after another to learn from Japan

Finally, the popularity of virtual currency in Japan is also the intentional guidance of the Japanese government. The emergence of virtual currency gives the Japanese government a new "future". The Japanese government hopes to establish a monetary system independent of the U.S. regulation through virtual currency, so as to revive its so-called great power status

however, we should also see that Japan's too loose virtual monetary environment has also led to many negative problems. For example, the frequent theft of virtual currency makes the Japanese government have to intervene in the asset security of the virtual currency market. As a result, Japan has strengthened the supervision of virtual currency, and the virtual currency market has become a bit quiet - exchanges such as hotcoin and BIGone have even given up Japanese language services

6. MBI is a pyramid scheme
this kind of MLM operation has the following characteristics:

1. Most of the above currencies are issued in a non constant amount, only speculation, and no commercial application

2. All of them belong to online financial pyramid selling, and the servers are all overseas, so it is difficult to investigate and deal with them

3. Short running cycle. Generally 3-6 months, to return money to the peak directly shut down the network running, change a vest to come back
digital currency crowdfunding platform the tokens of different crowdfunding projects on coin Ying China platform belong to application-oriented digital currency, with the mortgage of real assets, but the income is not high. Bitcoin and Leyte are traditional high-risk and high-income currencies.
7. If you want to talk about the hot currency recently, it's probably the platform currency slu of star guest exchange. More and more people begin to hold it. There is a certain innovation in technology. The silubium public chain behind it has carried out a wide range of commercial applications. The data is open and transparent, and the operation team has strength. It is highly recommended
8. Economy refers to the sum of social relations of proction. It refers to the sum of proction relations or social economic system formed by people in the process of material proction and adapted to certain social proctive forces. It is the foundation of superstructure such as politics, law, philosophy, religion, literature and art< Economy refers to the process of proction and reproction of social material materials. It includes the direct proction process of material materials and the exchange, distribution and consumption process determined by it. Its content includes proctivity and proction relations, but mainly refers to proctivity
3. Economy refers to the general term of a country's national economy. It includes all the material proction departments and their activities in a country, and part of the non-material proction departments and their activities. We usually talk about the economic situation of different countries from the perspective of national economy (this definition makes a logical mistake, that is, the definition of cycle).
9. That depends. Compared with other currency platforms, toobi is also very low, safe and formal. If there is no handling charge, I really dare not do it.
10. If it is a rectangle, roll it into a cylinder
cylinder diameter = length (width) of the rectangle ÷ 3.14
height of cylinder = width (length) of rectangle
