The worst date of virtual currency

1. 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.

2. First, most of the virtual coins issued today are decentralized, but in this regard, the virtual coins issued by the central bank must not be able to do so. It must be centralized and easy to adjust
Second, the value of money must be stable in a certain period of time, and it will not be as high as virtual currency such as BTC. The main purpose of the central bank's issuing virtual currency is to replace the current paper currency to a certain extent. That is to say, if a virtual currency assumes a fixed value of one yuan, it will be one yuan for a long time, It will not and will not be allowed that a virtual currency will rise to 100 or even more than 1000
thirdly, the most conservative estimate is that once issued, domestic enterprises or banks can choose whether to pay virtual currency or cash currency (RMB) when they pay wages or withdraw money. To a certain extent, cash will exist for a long time, instead of being issued all at once, all of them will be replaced by virtual currency, and all cash will be invalid, It's not realistic. It can only be said that it will be replaced graally
Fourth, the purpose of the central bank to issue virtual currency is to replace the current paper currency. Therefore, there must be a lot of similarities between this kind of virtual currency and the current paper currency. You can also directly replace the paper currency with the virtual currency, so you can have a good understanding of the nature of the virtual currency issued by the central bank. Therefore, the central bank's virtual currency is absolutely not allowed to appear, and the currency price is falsely high
therefore, it can be seen from the above points that the central bank's virtual currency is a new type of RMB, but it used to be physical, but now it is electronic and virtual. This is just like the use of real gold and silver in ancient times, and the appearance of "Jiaozi", that is, paper money, is only a kind of progress of the times. Other things are meaningless, just for the convenience of transaction, portability or personal property security. If you want to make money by investing in currency speculation, you can give up the idea. It's meaningless. If you just want to experience the freshness brought by the new currency, just wait quietly. Come out early, come out late, come out sooner or later. But then again, I'm looking forward to it.

3. After a golden time of virtual currency, it may make a lot of money in 2008. At present, although the virtual currency is graally getting hot again, the virtual currency authority is also being set up on the shelves. Then there is a risk that the virtual currency countries you buy and sell will admit it or not

4. Hello, let me answer your question

1 this question is very important. The foreign exchange market is different from the stock market. It has no exchange and is a discrete global trading mode. The essence of the foreign exchange market is the inter-bank market, that is, the market in which the world's major banks trade with each other. Because the trading volume between them is very large, ordinary investors can not participate in it, so there is a platform business. These platform providers build a bridge between retail investors and the interbank market. When retail investors place an order, they are actually trading with the platform business, and the platform business uses the funds of retail investors to trade with the bank. So, it is the platform that provides you with margin service, and the margin will stay on the platform for the time being. As for the economic line you mentioned, it is actually a secondary agent. They are the agents of platform companies, so they charge more commissions

2 your reasoning is a little complicated, so you should try to use the common measurement standards of foreign exchange instry for calculation. Take Europe and the United States as an example, assuming that the exchange rate is 13000, we call one ten thousandth of the exchange rate 1 point. One hand contract is US $100000. Suppose our account is US $10000 and the margin is 1%. Now we buy a first-hand contract with a margin of $1000. At this time, the margin balance is $9000. If the exchange rate drops by one point, our balance will decrease by 10 US dollars. If the exchange rate drops 900 points, the margin balance becomes zero. These changes are reflected in your account, and they are all immediate
in fact, when the margin balance is close to zero, it is generally about 10 points, that is, about $100, the platform will force you to close the position, that is, the so-called burst position. At this point, you have about $1100 left in your account. In actual transactions, margin is used to prevent sudden major changes in the market price, generally will not be used. Therefore, there is no need to worry about platform providers

however, in order to win customers, the mainstream platforms often adopt more radical methods. When the margin balance is zero, they still keep the position of retail investors and start to lose margin. Take the above example as an example, the margin balance begins to turn negative. For every 1 point decline in the market, the margin decreases by $10. When the margin remains about 10 points, that is, about $100, the platform will forcibly close the position. At this time, the account balance is only about $100, which is a complete burst

I think the above answers your third question at the same time

4 if you buy Canada Japan, platform vendors actually need to use US dollars as a bridge to exchange for two times, so the gap between Canada and Japan is the sum of Canada and the United States and Japan, or even larger. However, as a retail investor, you don't have to think too much about it. It's all the work of the platform Shang Dynasty. You just need to know that if you add one day fluctuation point, 0,1 contract fluctuation is 1 / (0.01 * US Japan exchange rate) US dollars

however, it is worth mentioning that the euro / yen exchange rate in the cross section is quite special, because the trading volume is very large, it is often direct trading, and it does not need to be mediated by the US dollar, so the currency spread is relatively small on many platforms

I hope I can help you.

5. This kind of virtual digital currency,
suspected of financial pyramid selling,
suggest not to participate,
in order to avoid economic losses.

6.

It's a government organization. It needs to be a civil servant to work in the administrative service center

Administrative service center, formerly known as administrative examination and approval service center, is a comprehensive administrative service organization integrating information and consultation, examination and approval and charging, management and coordination, complaint and supervision

the general office of the CPC Central Committee and the general office of the State Council issued the "opinions on deepening the openness of government affairs and strengthening government services" (hereinafter referred to as the "opinions"), which pointed out that it is necessary to graally establish and improve the government service system and give full play to the role of service center (i.e. government (administrative) service center)

departments with the function of administrative examination and approval set up centralized office windows in the center, which changed the things that administrative counterparts need to run multiple departments to only run the center, greatly facilitating the masses“ Changing the running of the masses into the running of cadres and "changing the running of the outside into the running of the inside" truly embodies the people-oriented thought and the purpose of serving the people of the people of the people of the people's government

< H2 > extended data

the legal rules and legal concepts closely related to the emergence of administrative examination and approval service institutions are as follows:

1, administrative convenience. Administrative convenience means that the administrative organs should use convenient ways as far as possible to facilitate the administrative counterpart to deal with the government, and provide thoughtful services for the administrative counterpart. Many laws in our country have stipulated specific and operable measures to facilitate the people, and some even directly define "convenience" as a legal principle

2. Administrative openness refers to the major administrative acts of administrative organs or administrative acts directly related to the rights and obligations of citizens. It is necessary to let citizens know through certain ways to protect the right to know of the administrative counterpart. The right to know of the administrative counterpart corresponds to the ty of informing that the administrative organ must perform

3. Administrative efficiency. The law mainly guarantees the administrative efficiency through some safeguard regulations

First, on the premise of guaranteeing the basic human rights of the administrative counterpart and fair administration, the summary administrative proceres should be stipulated to simplify the administrative proceres

Secondly, the system of limitation or period should be set so that every step of administrative action is limited by legal time and can not be delayed. The delay of the administrative organ may result in acquiescence in the rights of the opposite party

Thirdly, the system of substitution is stipulated, that is, when the administrative organ and its staff are unable to perform their legal obligations, the administrative organ at the next higher level or other staff will perform them on their behalf

the above-mentioned legal rules and legal ideas implemented in China's centralized administrative code are not only the crystallization of rational thinking of jurists and thinkers at all times and in all countries on how to use administrative power, but also provide legal guarantee for the emergence of China's comprehensive administrative service institutions

these legal rules and concepts remind and require governments at all levels to provide high-quality and efficient services in the most appropriate, convenient and visible way for the administrative counterpart, otherwise it will be against these legal rules and concepts

Due to the characteristics of office location, procere and working system, the comprehensive administrative service organization embodies the requirements of service administration, sunshine administration and efficient administration, so it is legitimate

7. Don't collect. Now Bank of China has banned bitcoin, and bitcoin is falling rapidly, so don't collect

8. There are too many dead virtual currencies, most of which have no innovation, and even many of them are just a means of pyramid schemes. As for which currency you said, there is no way to verify. Most of the dead coins have the following characteristics:
1. They make false propaganda under the guise of bitcoin, and do not have any innovation and application scenario planning
2. Pyramid schemes under the guise of bitcoin, such as Baichuan coin, Morgan coin, etc
3. This kind of virtual currency is pre g or has fatal defects
at present, the well-known digital currencies include bitcoin, Ruitai coin, Ruibo coin, thousand gold card, dog coin, etc
buying currency is risky, so investment should be cautious!

9. First of all, technically speaking, tic coin belongs to Shanzhai coin. Downloading the bitcoin source code and slightly modifying the source code (quantity, encryption method, etc.) will proce tic coin. This is also the technical basis of all Shanzhai coins. This is also the main reason why there are more than 3000 virtual currencies on the market. Secondly, in terms of type, it belongs to enterprise currency. Although the tic is claimed not to be controlled by the central bank, every investor has a targeted investment object (the so-called foreign Association selling mining machines), which means that the tic is not a decentralized virtual currency
in the field of virtual currency, all the so-called virtual currencies under the banner of cloud mining machine are all circle coins and scam coins, which are generally packaged in large packages. However, this kind of non decentralized currency has no long-term investment value. Once the central institution goes bankrupt, the tic coin is worthless. The reason why there is a price now is that there are companies and institutions promoting it
there are many loopholes in the tic trading platform, and the domain name of the trading website is personal. The organization never announced the company's operation team, personnel composition, fictitious the Research Office of Tik coin in the Cayman Islands (no such organization exists after investigation), no one abroad knew about the coin, all communication was carried out through QQ and wechat, and there was no voice of doubt in the group. It is said to have been monitored
in addition, the reason why bitcoin is superior to any other open source virtual currency is not because of its technology, but because of the trust market formed by the free market in the past seven years, which can not be compared and surpassed by any other virtual currency. So, compared with bitcoin technology, it's meaningless
to sum up, tic money is a kind of counterfeit money. It is driven by institutions and not decentralized. It has a price in the short term, but it has no long-term investment value. The less advanced people are the takers. This can be verified by time—— Seagull teacher, eight years of Internet Finance veteran.
