I don't know about virtual currency

1.

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

extended data:

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

2. Virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins.

3. Money appears with the constant change of the form of commodity exchange value. At the end of the primitive society, when people had surplus procts, they had to exchange between different tribes. For example, if a tribe had surplus sheep, it was necessary to exchange them with others. By chance, a man with a rabbit also exchanged them. When two people met, one sheep exchanged for five rabbits. It can be seen here that the value of one sheep is represented by five rabbits. This sheep is now represented by five rabbits, which is an initial form of value expression. With the progress of society and the emergence of surplus procts, this kind of transaction is more and more frequent. Finally, people recognized silver and gold as the material to measure the value of all commodities, so money came into being

it can be seen that money itself is a kind of commodity, but this kind of commodity has a special function. It can be exchanged with any other commodity and acts as a general equivalent.

4. In the notice on preventing bitcoin risk issued by the central bank and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell freely at their own risk, denying its monetary attribute. All financial institutions are not allowed to provide bitcoin related services. Bitcoin related websites must be put on record and require users to carry out real name authentication. Zhou Xiaochuan, central bank governor, said in an interview that bitcoin is a tradable asset like a stamp

in a word, virtual currency represented by bitcoin is legal in China, but the government takes a cold attitude towards virtual currency, which is neither positive nor negative. Most of the major countries in the world also adopt a cold attitude towards virtual currency

since 2015, the popular virtual currencies are bitcoin, Laite coin, Fuyuan coin, doggy coin, reborn coin and so on.

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.

1、 7 * 24 hours trading

the trading time of digital currency is very long, 24 hours a day, 7 days a week, 365 days a year. As long as you like, you can trade whenever you want. There is no time limit

friends who have worked in stocks and futures know that stocks and futures have trading time limits. A few hours of trading time in a day is not enough. Digital currency is a real all-weather trading, which can meet the needs of friends who trade in different periods of time. You can trade whenever you are free, even on weekends, It's just so willful

Second, there is no limit on price rise and price fall.

there is no limit on price rise and price fall in the trading of digital currency, that is to say, it can rise and fall freely without any limit. You can say that there is a huge income space, but you can also think that there is too much risk. This is a matter of different opinions. There are good and bad, because the income and risk are positively related. Digital currency trading platform "currency exchange"

the price demand of the market can be truly reflected without the limit of rise and fall, because the rise and fall of the price is a very natural process. When everyone is optimistic, it will rise, and when they are not optimistic, it will fall. This is the law of price fluctuation, and the limit of rise and fall only adds human intervention to the price fluctuation to slow down the price fluctuation, But it can't really stop the price movement. Therefore, there is no limit on price fluctuation, which is the most real price fluctuation and truly meets the market demand and expectation

(3) t + 0 transaction: Generally speaking, the digital currency bought on the same day can be sold on the same day, that is, it can be sold with the buyer. It sounds very powerful. If the digital currency you buy makes money, you can sell it immediately and make it safe; If there is a little loss, you can also sell it immediately to prevent the loss from further expanding. All t + 0 trading system is really very practical, can be very flexible to deal with the hands of the position

Four, two-way transaction digital currency can not only buy long, but also sell short. Most of my friends basically understand buying long and bullish, but they don't understand selling short and bearish. This is actually a reverse thinking, the key point is to judge the direction of rise and fall accurately, at the same time, there is a price difference to earn on the line

for example, we can buy at a low price and then sell at a high price to earn the price difference (buy long and be bullish); You can also sell at a high price first, and then come back at a low price to earn a difference (sell short and put). The operation steps are almost the same. It's just a direction of business

Five, margin system margin trading is to pay a part of the margin to buy the relevant digital currency, just like when you buy a house, you only need to pay a certain down payment to buy the house. This is the legendary leveraged trading, but at present only some platforms have leveraged trading. Margin trading (Leveraged trading) has achieved the goal of "small, broad and big", maximizing the efficiency of capital utilization, expanding both profits and losses. We can treat it dialectically

8. How to develop a game with cocos2d-x? The result of this problem should be a process. I will explain it from some long-term PC game development experience combined with the functions of cocos2d-x. First, determine the game plan. Determining the plan determines the scale of the game and the required moles.

9. The K-line data of matrix data is updated in real time. The delay should be controlled within milliseconds. Generally, if I directly input the digital currency data information I need, I can give it back immediately. Matrixdata.io or you can try it directly
