The practicability of virtual currency

1. Here's bitcoin
bitcoin price has been cut by the waist
how to implement blockchain application is still the main problem. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage. Looking back to the second half of 2017, the price of bitcoin almost reached a new high every day, and finally reached the peak in the South Korean exchange with the highest premium in the world - about 140000 yuan per piece. On June 3, 2018, as of press time, coinbase bitcoin trading platform quoted 49688 yuan, and the price of bitcoin has been cut. Since the beginning of this year, the price of bitcoin has rarely seen eye popping ups and downs, and the overall trend of monthly decline
bitcoin development status
according to the data of the in-depth analysis report on business model innovation and investment opportunities of the blockchain instry released by the foresight Instry Research Institute, bitcoin prices showed a downward trend in May, with the overall market value falling from US $157.3 billion at the beginning of the month to US $127.4 billion at the end of the month, a decrease of 19%; In addition, there are 444000 active addresses and 197000 transfers per day. From the trend point of view, the number of active addresses and daily transfers are positively correlated with the transaction price. In May, the overall trend is volatile, and the downward trend is very obvious
reasons for the steady decline of bitcoin in the past half year
how to understand the "steady decline" of bitcoin in the past half year? There are two main reasons: firstly, the most important reason is that institutional investors and speculators who have accumulated a large number of "profit" are cashing in their profits and leaving the market; Secondly, before the blockchain instry has no real application and profit model, the rise of bitcoin price can only be regarded as speculative speculation. In addition, it is an undeniable fact that the Central Bank of China has made a decisive move to close the bitcoin trading platform, which has achieved remarkable results in preventing bitcoin speculation
at present, the domestic bitcoin exchanges have basically moved to foreign countries, which has nothing to do with China. Investors operate on those platforms at their own risk
the current market is not very good. Only when the market is good, can investors find ways to participate in bitcoin investment. As the total market value of the coin circle is still small, with more blockchain applications, there is still potential in the future
over consumed blockchain
e to the "tepid" price of bitcoin, blockchain, as its underlying technology, has reached the level of "known to all women and children", and even surpassed bitcoin in recent years
recently, a series of related reports are suspected of making up for the number and full of hype, and blockchain has obviously been over consumed. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage
with the graal deepening of the understanding of blockchain technology, domestic enterprises have laid out blockchain technology, platforms and applications, including Internet enterprises such as network, Tencent, Ali, Jingdong, Netease, major banks, financial enterprises such as Ping An of China and Huawei. In terms of application, China actively explores and promotes blockchain + applications in the form of alliance chain and private chain to help solve the pain points of related instries, improve efficiency and rece costs.

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.

Virtual currency is not a real coin, but a virtual thing. Virtual currency also has its own value, because it is a kind of training for investors

they think that some virtual currencies will have a great market, so at this time, as an investor, unique vision is very important. If you enter too late, then the virtual currency may not have any value. If you enter too early, it may not be what you expect. So at this time, the entry time is very important

So virtual currency can also make us grow rapidly, which is the judgment of the overall situation and the learning of knowledge. So virtual currency, for us, is a kind of income. Of course, we don't know how much this kind of income is in the early stage. Secondly, it enables us to learn quickly and improve our knowledge literacy, and it can also learn through continuous practice and combine practice with learning. These are exactly what we need to do, He also plays the role of supervision

4. This view is controversial. China's central bank defines bitcoin as a special Internet commodity, while the United States recently classifies bitcoin as a commodity. Of course, the attitude of European countries towards bitcoin is relatively ambiguous. Germany is the first country in the world to recognize bitcoin as a unit of account. However, most people in the currency circle regard virtual currency as currency. Let me take bitcoin as an example to illustrate:

bitcoin has value because it is useful as a form of currency. Bitcoin has the mathematical characteristics of money (persistence, portability, interchangeability, scarcity, separability and identifiability) rather than relying on physical characteristics (such as gold and silver) or the trust of central power (such as fiat money). In short, bitcoin is backed by mathematics. With these characteristics, a form of money to have value requires trust and use. This can be reflected in the growing number of users, businesses and start-ups. Like all currencies, the value of bitcoin comes directly from people who are willing to accept it as a means of payment, which is the only source

of course, some domestic digital currency scholars began to take bitcoin not as a kind of currency, but as a shortcut. Teacher Shaqian proposed the concept of currency business circle. Perhaps inspired by the recent emergence of a currency called Fuyuan coin in the jewelry instry, it is very innovative to use Fuyuan coin to replace the traditional business integral system.

5. There are no more than the following kinds of people touting virtual currency:
the first kind is the big guy who pretends to be confused. They boast about the greatness of virtual currency, in fact, just to sell their own coins, and then make their wealth more and more. This is the same reason that Mimeng's articles incite emotions. It's just to let people read more of her articles to sell advertisements. As for whether it is true or not, who cares
the second kind of people is the media outside the circle. In fact, they don't know anything. The purpose of their blowing together is to bring traffic. It's all for sale. It's just different. They follow together to brag, will have more traffic attention, advertising can be more valuable. If the business is not good, change the vest and continue. That's what we media and finance are doing now. True or false is not so important, the important thing is to bring them income, which is enough
the third kind of person is the leek of coin circle. In fact, they don't have the ability to think independently. They are superstitious in aura. They watch the big guys and the media blow, and then they really believe in it. They also blow,,,, and then they are the ones who take over. It is commonly known as "no brain blowing, no brain blowing". It lacks the ability of independent thinking, and does not carefully analyze things. It is respect to blow first and respect to blow first. Blind, therefore, only then dish's life.

6. Views on virtual currency
from q-coin and counting roll used to buy props to bitcoin which can be exchanged with us dollar and euro today. It shows that the utilization rate and universality of virtual currency are graally increasing. I think this kind of virtual currency has both advantages and disadvantages. Virtual currency makes up for the deficiency of currency, but it will not replace the real currency
1. Security of virtual currency. The day before yesterday, a bitcoin trading platform headquartered in Japan was favored by many people. However, e to the loss of 750000 bitcoins from customers and 100000 bitcoins of its own, the company had to file for bankruptcy protection. This fully shows that the security of virtual currency is difficult to guarantee
2. The use of money cannot be regulated. The problem is that there is no manager similar to the central bank. Due to the strong anonymity, it is easy to be used for illegal transactions such as speculation and drugs, as well as money laundering. Without the network of financial institutions, it is difficult to grasp their liquidity, which will bring difficulties to taxation
although it has many uncertainties, virtual currency is very effective and reliable to a certain extent
1. The possibility of inflation of virtual currency is small, and it is not affected by policy. Avoiding the influence of the central government on finance, virtual currency can prove the stability of its value because of its limited circulation. It will not raise prices and lower the value of money because of the increase of money supply
2. Strong circulation. People can use bitcoin to trade anywhere in the world where there are networks and computers, which is very convenient
it not only saves time, but also saves a lot of transaction costs
after comparison, I think that the virtual currency will be saturated and will not pose a threat to the real currency. On the one hand, in the backward regions and countries, they rely more on currency, resulting in a gap with the developed regions. On the other hand, with the development of network technology, the security of virtual currency will be more and more difficult to determine. It is also very difficult for people to use a lot of money in the form of virtual currency in huge investment. Especially in a country with traditional culture such as China, people are more confident that they will hand over their property to the financial instry such as banks, rather than in the online world like flowers in the mirror< There is no comparability between bitcoin and stock. Stock is people's profit expectation for a company. For example, a company constantly proces new procts to increase its wealth. People can obtain wealth growth with the company by holding shares of the company. And the stock is an investment proct, without monetary attribute, it is impossible to say how much ICBC stock an iPad is worth. On the contrary, like bitcoin, the stock can be converted into legal currency through the exchange to purchase the iPad. Similarly, in the so-called companies that accept bitcoin payment, all of them are marked with legal currency. They accept bitcoin through a third-party company, and finally receive legal currency from a third-party company
therefore, stock is people's expectation for the future development of a company, and it is an investment proct. There is no comparison with bitcoin, which clamors to become a currency
2. The existence of money lies in circulation and pricing. A thing that has been reced to a speculative tool since its existence, expecting appreciation and redistributing wealth can not become money
3. As cndx God said, bitcoin will have 2.0 in the future, which will be seamlessly connected with 1.0. That's funny. Why should the inventor of 2.0 connect with 1.0? Just as bitcoin does not connect with RMB, it is another opportunity for wealth redistribution
4. The existence of virtual currency can only meet the money laundering needs of a small number of people, so there is a market. For example, if someone wants to launder US $1 million recently, the ratio of bitcoin to legal currency will change, which is also in line with the market rules. Of course, money laundering is risky. If you buy one million dollars of bitcoin, you will hold it forever without losing any money
5. My legal currency is in the bank. If I lose it, I can still get it back with my ID card. Is my bitcoin password gone? Who should I go to
6. The currency expected by cndx will not be lost. At most, it will play in a certain circle just like Q currency
7. This thing is the proct of anarchism. If you want to embody value, you can only do it without government. The distribution of wealth depends on power and blood. For example, if you hold 10000 bitcoins, ZF says not to use them, and you say I'll use them. Bang, you're dead. Oh, bitcoin has appreciated again, because the total amount is less than 10000.

7. No
there are three recommended appraisal platforms:
the most comprehensive and authoritative digital currency query website in the world
international one-stop virtual currency service platform
global digital currency trading market

8. At present, bitcoin and Ethereum are good. According to the data of Hufu exchange, their prices have shown an upward trend in the past year.
