1. digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world
the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation
types of digital currency
according to different issuing or consensus mechanisms, it can be divided into four categories:
1, proof of work (POW)
proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk
3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state
4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC
according to the project type, it can also be divided into four categories:
1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin
2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont
3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)
4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.

2. Blockchain is an emerging instry, which has been highly valued by all countries. It is called the fourth instrial revolution and will have an immeasurable impact on society. Blockchain is the literal translation of block and chain. Each block stores the transaction data within a specified time, and forms a non tamperable, all staff shared distributed ledger through cryptography
digital currency and virtual currency are actually different names. They are tokens issued based on blockchain technology. Behind them are a series of computer-generated complex codes. At present, there are thousands of digital currencies in the market. The safest and most powerful digital currency is bitcoin
digital currency is also a high-risk and high return investment proct, through appropriate investment strategies, you can get rich returns. If you have spare money, you might as well put some of it into the digital currency. There will be unexpected surprises.

3. The virtual currency we use on the Internet, such as q-coin or other game currency, is strictly virtual goods or intermediate goods. It is not money and does not have the purchasing power of legal tender. Bitcoin, which is more talked about in the market, is also different. It is a decentralized virtual currency realized by using blockchain technology, which is easy to facilitate money laundering. Therefore, the application of blockchain technology should not be copied. If the central bank issues digital currency, it should be a kind of centralized currency. The legal currency issued by the central bank, encrypted and supported by national credit, should meet the regulatory requirements
a few days ago, Indian Prime Minister modi announced the issuance of a new currency aimed at combating tax evasion and money laundering. In fact, if the central bank issues digital currency with perfect technology and mature mechanism, it will have better effect. Because the digital currency, in addition to anti-counterfeiting, with the help of blockchain technology, makes the capital data traceable and highly transparent. These features can also be used for macro data statistics and monitoring, which has positive significance for big data risk control
as for what bank digital currency is, the central bank requested at the meeting on January 20 this year that the research team of the people's Bank of China should actively absorb the important achievements and practical experience of digital currency research at home and abroad, continue to promote on the basis of preliminary work, establish a more effective organizational guarantee mechanism, and further clarify the strategic objectives of the central bank in issuing digital currency, Do a good job in tackling key technologies, study the multi scenario application of digital currency, and strive to launch the digital currency issued by the central bank as soon as possible.

4. The market value of digital currency is equivalent to the market value of stocks in circulation, which is calculated by multiplying the market price of digital currency by the quantity in circulation. The formula is: market value = current price of digital currency * quantity in circulation
generally speaking, the market value is determined by the quantity in circulation rather than the total circulation. Because circulation quantity can better measure market value. The locked and predetermined ones can not be sold on the open market, which will not affect the currency price, so it will not affect the market value. The method of using circulating quantity is similar to using circulating shares to determine the market value of traditional investment
at present, the market value of bitcoin has reached more than 70%, occupying an absolute dominant position, while the market value of other currencies is declining. In the long run, the market value of the whole digital currency is growing. If we can seize the opportunity, we will get rich returns.
