Basic knowledge of digital virtual currency
From 2015 to 2017, the price of bitcoin increased from more than $100 to $17000, a 100 fold increase. Today, the market value of various numerical currencies is more than 700 billion US dollars. The myth of their benefits is not nonsense
but there are many things behind the chaotic digital currency. You may ask why air currency can be listed on the stock exchange? It's very simple. The exchange also has to charge a part of the fee. Raise the price and then sell it to make money. So the question is, how to identify air currency
first of all, you need to look at the projects behind the digital currency and see what their team background is. Generally speaking, teams without experience in the instry tend to earn money, but how much experience do they have? It is better to be able to participate in the construction of Ethereum and bitstock communities. Such a team is often more reliable. This requires investors to have a certain screening ability to identify good or bad
secondly, there is no way to implement many projects. How can we identify them? In addition to the ability of the team, we also need to see the feasibility, which requires us to systematically learn the knowledge of bitcoin and blockchain. For example, Zhu Jiawei, the COO of fire coin network, learned the blockchain from 0 to 1, and clearly described the development process of bitcoin and blockchain in the form of audio and text. Besides, don Tapscott and Alex Tapscott's "blockchain revolution" are worthy of careful taste
moreover, the bubble of digital money is very large nowadays. In the bubble, it is not difficult to make money, but the key is not to be greedy. Long term holding is not good, but it can be operated in a short term. You can make money if you want. However, the key is that people are all profit-making and greed is their nature. Therefore, many people do not accept what they see. They originally made money, but later they lost everything. The gain is not worth the loss. Therefore, it is necessary to control greed
e-money: in fact, it is the electronization of legal currency, including our common bank card, online banking, e-cash, etc; There are also third party payments developed in recent years, such as Alipay and WeChat payment. No matter what the form of these electronic money is and through which institutions it circulates, its original source is the legal money issued by the central bank
virtual currency: virtual currency refers to non real currency, and its existence state is intangible. The most important difference between virtual currency and electronic currency in narrow sense is the difference of issuers. Virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, game currency, q-coin, and ticket counting are mainly limited to circulation in a specific virtual environment
digital currency: a digital currency that applies the latest digital network technologies such as blockchain and has the characteristics of Distributed Accounting, unique encryption technology and decentralized settlement. Of course, digital tools with these characteristics must be supported by national credit if they want to become sovereign currency or legal tender
commonly referred to as Q / currency and bitcoin, all belong to virtual currency. Compared with digital currency, the most fundamental difference lies in the difference of issuers. Virtual currency is the electronization of illegal currency. The issuer is not the central bank, and it can only circulate in a specific virtual environment, such as Tencent Q / currency and other game currencies; Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal digital currency.
it is also closely related to Internet technology and has the attributes of payment and circulation. The central bank's "digital currency" is closely related to bitcoin. But bitcoin is a kind of digital currency, but digital currency is not just a form of bitcoin. Although the central bank's "digital currency" veil has not yet been lifted, there must be many differences with bitcoin
first of all, the issuers are different
most currencies have an issuer. For example, RMB is printed and issued by the central bank. But bitcoin does not have a centralized issuer. It is generated randomly based on an algorithm. Anyone can mine, buy, sell or receive bitcoin
secondly, the acquisition methods are different
bitcoin is the result of unremitting "mining" by some people who master the algorithm. These real it experts need to search for 64 bit numbers by computer, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network and obtain the corresponding bitcoin
but the digital currency issued by the state is bound to face the people of the whole country, rather than some network experts. When the country strives to achieve the goal of Inclusive Finance, how can it only tailor a currency for Internet experts? The national version of "digital currency" is bound to help the realization of Inclusive Finance, facing the most extensive groups
in addition, the pricing is different
in the face of bitcoin, which is becoming more and more difficult to "dig", many experts are more energetic like upgrading to fight monsters. With the increasing difficulty of "mining", the price of bitcoin has also soared and fluctuated greatly
a national currency has to try its best to maintain its own stability. Naturally, it is impossible to price according to the difficulty of acquisition, just like collectibles, because of scarcity
in addition, the application range is different
at present, all countries, including China, do not recognize the monetary attribute of bitcoin. Some organizations may have accepted donations from bitcoin, and some supermarkets have said that they can pay with bitcoin, but this is only within a very small range
as a digital currency issued by a country, it must be able to meet the largest range of payment needs, especially with the evolution of mobile Internet, cloud computing, blockchain and other technologies, and under the background of great changes in global payment methods, the central bank's digital currency needs to meet the global payment needs
if the central bank's "digital currency" is very different from bitcoin, how is it different from virtual currency
people who have used QQ should be familiar with QQ coins. They need to change their clothes for QQ avatars and change their backgrounds for QQ spaces. Many Tencent online games also need QQ coins to recharge. Like this, there are many virtual currencies based on the network, such as the online currency of the network company, the recharge voucher of the game company, etc
as far as the scope of application is concerned, most of these online currencies are used to recharge games, purchase equipment and props, and cannot be paid offline; As far as the exchange method is concerned, in principle, virtual currency can only be purchased with real currency, but it is not allowed to convert virtual currency into real currency; As far as issuance is concerned, it is launched by enterprises themselves, some of which are like "vouchers" rather than real currency
therefore, although the issuance of "digital currency" by the central bank inevitably requires payment transactions on the Internet, the principles and methods are different from those of virtual currency
especially at present, when many enterprises issue virtual currency, e to their own lack of risk prevention and control and security awareness, they leave an opportunity for some criminals to swipe bank cards, sell stolen goods and launder money. If the central bank's "digital currency" is issued, whether it will replace these online virtual currencies and make the online payment environment safer, healthier and more transparent is a question worthy of consideration.
