Analysis of whether virtual currency is really wealth
virtual currency and electronic currency are not the same concept
the definition of e-money is to convert a certain amount of cash or deposit from the issuer and obtain data representing the same amount. By using some electronic methods, the data can be directly transferred to the payment object, so as to pay off the debt. E-money means that consumers pay traditional money to issuers of e-money, and issuers store legal money of equal value with traditional money in electronic devices held by consumers P>
electronic currency is the electronization of the legal tender, including our common bank cards, Internet banking, electronic cash, etc., as well as the third party payment developed in recent years, such as Alipay, fortune paid and so on. No matter what form these electronic currencies are and through which institutions they circulate, their original source is the legal money issued by the central bank
but virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, Tencent Q currency and other game currency, such virtual currency is mainly limited to circulation in a specific virtual environment. After the emergence of bitcoin, through the blockchain technology to better solve the problem of decentralization, distrust, to achieve global circulation, is sought after in the world. Electronic currency and virtual currency are collectively referred to as digital 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.
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.

the fixed effects model has n different intercepts, one of which is for an indivial. These intercepts can be represented by a series of binary variables
the fixed effect model refers to the experimental design in which the experimental results only want to compare the differences between the specific categories or categories of each self variable and the interaction effects between the specific categories or categories of other self variables, and do not want to infer other categories or categories not included in the same self variable. Researchers want to know the different effects of teachers' cognitive types on children's learning mathematics in different teaching methods. Teachers' and students' cognitive types refer to site dependent and site independent, while different teaching methods refer to heuristic, lecture and sequencing. At the end of the experiment, the researchers only explained the interaction effect between the two types and the differences between them, but did not infer other cognitive types or the fourth teaching method. This kind of experimental research mode is called fixed effect mode.
