1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin
However, some digital currencies have independent issuers The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 milliondigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold
today's digital currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
illegal digital currency
in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life
not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence
therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing
2. It is very clear in the speech of the central bank that the digital currency is M0. What is M0? M0 is cash. We speculate that the basic framework for the central bank to issue digital currency in the future should be a two-tier structure. The core is the database of the central bank, and the periphery is the blockchain of different instries, regions and third parties. Why? Only by using a decentralized system in the second layer can you ensure that the money is controlled by the users themselves and that the digital currency really becomes M0
we speculate that once the central bank issues digital currency in the future, the periphery of the structure must be a decentralized system. At present, blockchain is the best choice
when talking about digital currency, the central bank also mentioned another concept, which is called programmable currency. How to understand? For the computer, it has a certain internal self-control function. Take the early object-oriented language as an example, it requires at least two functions, one is the constructor, the other is the destructor. You have to solve the problem of its creation as well as its extinction
through programming, the central bank can control the whole life cycle of money creation, circulation and withdrawal
in the absence of digital currency and programmable currency, the currency issued by the central bank circulates freely in the society. How to return to the cage in the end? One is the return of derivative currency of commercial banks, the other is the return of basic currency of central bank. The former is controlled by the central bank through deposit reserve and other policies, while the latter is controlled by the tax system. If we go up to programmable digital currency in the future, the central bank will have much more control. Even in circulation, control can be increased. That's why central banks are very interested in blockchain technology.

3. Digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digital currency. Digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community.
4. Digital currency platform development needs professionals to be responsible for, but now digital currency technology has matured, the difficulty of development has become very simple, has become a standardized technology. Today's digital currency technology is not the highlight, but the application scenario of this kind of digital currency
the birth and popularity of bitcoin all over the world depends on the concept, which is in the foreword of the times. However, bitcoin has been preconceived and cannot be replaced by other digital currencies. Although some counterfeit currencies were popular for a while later, they slowly went down in the end, only bitcoin strengthened. Puyin is another shortcut, as a standard system of digital currency appears, behind the endorsement of related tea assets, its value is recognized by the society.
