virtual currency refers to non real currency

digital currency:

digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

3. Cryptocurrency:

4. Token (token):

a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English

Second, the characteristics are different:

1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency

2. Digital currency:

is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities

extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

2. In a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a way of sequential connection, and it is a distributed account book that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
nowadays, the mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea based digital currency Puyin is developed based on blockchain technology.

3. Since 2008, Nakamoto has proposed bitcoin, a peer-to-peer cash trading system. Since then, it has entered the eyes of the world.

4. If you look closely at these two fields, you will find that they have begun to develop away from each other. Although digital currency is technically inseparable from blockchain, blockchain technology is not limited to digital currency. It is favored by various technical companies in terms of proct traceability, data transparency and distributed consensus. So what impact does the central bank's entry into digital currency have on the blockchain instry, It's not going to change much. At present, the ant gold clothing behind Alipay is the largest patent application company in the global block chain.
what benefits most from this is the domestic currency circle. In 2017, digital currency and related fund-raising activities were banned in China, which is quite negative in the eyes of ordinary people. In fact, the central bank's initiative to explore into cryptocurrency is the recognition of the core concept of digital currency. With this incentive, domestic enterprises will actively enter the instry and inject fresh blood into the instry, which is the most important
about this, you can see the reports of blockchain media, such as golden finance, coin easy to know column, chain news and so on.

5. 1. Blockchain is an account book for recording digital currency transactions

taking bitcoin as an example, it does not have an entity form, but exists in a special account book. All bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of bitcoins owned by each user. If a person owns bitcoin, it means that he can find the relevant transaction records in the ledger

the ledger mentioned here is a software that we can download from bitcoin's official website, and the underlying technology used in this software is blockchain. In order to facilitate understanding, we usually say that blockchain is the ledger

the reason why blockchain is used as the underlying technology of ledger is to realize the feature of digital currency decentralization. It can be said that the starting point of a series of problems and solutions of digital currency comes from decentralization
2. Blockchain is a technology to ensure the safe use of digital currency. As we all know, blockchain technology has the characteristics of encryption and non tampering, which can rece the probability of errors in the use of digital currency to 0. Because digital currency requires higher encryption, it must be supported by blockchain technology. At present, not only many instries in China are using blockchain technology, but also many foreign countries are actively using blockchain technology.

6. Blockchain is its underlying application technology, and digital currency is its currency. Its practical application has little impact on the fluctuation of digital currency
when the economy is stable, it doesn't rise. When the economy is in turmoil, people begin to store digital currency. Of course, it is convenient for some corrupt elements
now the economy is stable, the digital currency is in a bear market, the financial crisis, the crisis, and only when there is a crisis can there be an opportunity. At that time, the rapid growth of bitcoin was the opportunity in the financial crisis. Don't worry, there will be a bull market in digital currency, which is expected to come in the second half of next year

7. Blockchain technology is considered as the "golden key" to solve the social credit problem by technical means
I may have heard the saying "artificial intelligence is proctivity and blockchain is proction relationship", which also shows the development potential of regional chain
on the public blockchain, there can be no digital currency. So regional chain fire, digital currency is the same, and the Internet fire is a reason.

8. Usdt is OK, how much to start with
for others, you can only say that as long as it is a new digital currency with low price, you can start a little bit!

9. Ete digital currency platform is a real estate information platform, the above information is true, can help us improve work efficiency. I hope my answer can solve your problem
