Three attributes of digital currency

1.

digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)

digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes

based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

extended information:

the process of digital currency trading through the platform is as follows:

(1) investors should register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time

(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures

(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed

2. In short, virtual currency, also known as cryptocurrency, is issued and circulated on the Internet and mainly traded through exchanges. Because it runs on the blockchain, every transaction on the chain is semi anonymous and tamperable, so it ensures the circulation and a certain degree of security. Mainstream digital currencies include bitcoin, Ethereum and Leyte. Digital currency is inseparable from blockchain technology. The core idea of the latter is to ensure that all nodes have a consensus on a transaction through transaction broadcast and irrelevant node confirmation. Once the consensus is formed, transaction confirmation, block excavation and reward will follow. This reward is digital currency. If digital currency wants to have value, it can't do without people's recognition of its value. The more recognition, the more people want to have it, and the exchange came into being. If it's Xiao, it's not recommended to go to big exchanges (currency security, currency, OK) to play contract leverage. You can go to small exchanges to practice, such as currency easy, etc. You can also learn about the coin circle information. The development of the whole coin circle changes every day, very fast
there is no price limit for P.S. digital currency trading, so investment should be cautious!

definition of digital currency:

the alternative currency in the form of electronic currency belongs to digiccy
digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as the digital expression of value, which is not issued by the central bank or authorities, nor linked with legal currency, but because it is accepted by the public, it can be used as a means of payment, and can also be transferred, stored or traded electronically
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm

the core characteristics of digital currency are mainly reflected in three aspects: first, e to some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; ② Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; ③ Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough

the emergence of bitcoin poses a great challenge to the existing monetary system. Although it belongs to the generalized virtual currency, it is essentially different from the virtual currency issued by network enterprises, so it is called digital currency. This paper compares digital currency with electronic currency and virtual currency from the aspects of issuing subject, scope of application, issuing quantity, storage form, circulation mode, credit guarantee, transaction cost and transaction security.
