Utilization rate of 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. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
in recent years, the excessive issuance of banknotes has led to the aggravation of inflation, the frequent security crisis of third-party payment, and the graal maturity of blockchain technology, so decentralized digital currencies such as bitcoin, Ethereum and reborn have emerged. Digital currency has the advantages of low transaction cost, fast transaction speed, high anonymity and fixed amount of money
At the same time, the use scenarios of digital currency become more and more abundant, which makes the user acceptance grow. At present, the use of digital currency has covered all kinds of scenes, such as shopping consumption, wage payment, transportation, travel, takeout settlement and tuition payment. The expanding landing scene has also brought a wider range of consumers. In general, although the number of users of digital currency still accounts for a small proportion of the total population, the number of users is growing. At present, the utilization rate of digital currency has exceeded 10% in 10 countries around the world In June 2019, Facebook launched Libra virtual cryptocurrency, which has caused worldwide influence. The emergence of Libra may form a global super sovereign currency, thus affecting the traditional transaction settlement currency. For China, the emergence of Libra, on the one hand, will have an impact on China's traditional currency and threaten the sovereign status of China's currency; On the other hand, because RMB is not included in Libra's basket of currencies, it will rece the reserve demand of RMB by central banks, thus hindering the internationalization of RMB. In response to this threat, CCTV timely launched the central bank digital currency. In September 2019, according to China Daily, the central bank's digital currency closed-loop test has begun, and the central bank's digital currency is about to come outcoincidentally, in addition to China, central banks around the world have also announced that they will launch a centralized digital currency based on national credit. In 2015, Ecuador took the lead in launching the national version of digital currency, which can not only rece the issuance cost and increase the convenience, but also enable people in remote areas who cannot have banking resources to obtain financial services through the digital platform. At present, Canada, Brazil, Norway, the United Kingdom and other countries are studying the central bank legal digital currency, while the Bahamas, Sweden, Russia and other countries are discussing the possibility of digital currency issuance. Generally speaking, the developing countries which have received a great impact on digital currency have supported legal digital currency for financial inclusion, breaking through sanctions and other reasons

Digital RMB is the legal tender in digital form issued by the people's Bank of China. It is operated by designated operating institutions and exchanged to the public. Based on the generalized account system, it supports the loose coupling function of bank accounts, is equivalent to banknotes and coins, has value characteristics and legal compensation, and supports controllable anonymity{ RRRRR}
that is to say, like cash, we should not only provide a wide range of digital RMB services to the public in the future, but also ensure that all the public can easily obtain and use digital currency. Mu Changchun pointed out that in the process of issuing digital RMB, on the one hand, all commercial banks should participate in the circulation service; On the other hand, it is also necessary to ensure that all people, including the poor areas and the digital vulnerable groups, are provided with inclusive and easy-to-use digital central bank currency to avoid the digital divide and financial exclusion& ldquo; We have also been developing digital RMB procts suitable for the elderly and those who exclude the use of intelligent terminals& rdquo; He said
Suzhou will open on December 12; Double 12 Suzhou Shopping Festival & quot; Activities. Just recently, Suzhou announced that it would issue a total of 20 million yuan of digital RMB consumption red envelopes to the citizens who meet the requirements. The amount of each red envelope is 200 yuan, a total of 10 red envelopes. The distribution method is lottery. At that time, some of the citizens who signed up for the lottery will participate in the offline wallet experience. Perhaps most of them, after seeing this news, are envious of the Suzhou people; What is digital RMB; This question will be raised again and again. So, what is the digital RMB? What is the difference between Alipay and WeChat, which we usually use? The three points above strong>
are the main differences between the digital Renminbi and Alipay and WeChat. In addition, the emergence of digital renminbi will not threaten the existence of Alipay or WeChat. The digital renminbi will not completely replace banknotes in a short time. After the official launch of the digital renminbi, the public can choose to use traditional banknotes or digital Renminbi by themselves. It is reported that since May, in some areas of Suzhou, a small part of civil servants' wages have been paid in digital RMB, while most of the rest are still paid in traditional ways, so the two are not contradictory
the replacement of paper money by digital currency can only be realized in the eastern coastal developed areas and some big cities, but it is unrealistic in some remote areas, and the infrastructure can not keep up
bitcoin, lightcoin and decent are known as global circulation, but in fact, the scope of circulation is very limited.

So how to distinguish these black heart coins
with the popularity of Shanzhai coin market, some unscrupulous developers, after developing a virtual coin, organize themselves to take a part of the total amount of virtual coin issued as their own before putting it on the market. This proportion is generally less than 2%, and a few even reach 90%. When the virtual currency has a certain value or on the trading platform, a large number of sell-off cash, so that miners and investors suffer huge losses, so the first factor to choose virtual currency is zero pre dig. So how to distinguish whether a virtual coin is zero pre dig? Here is the identification method. 1. Play the wallet and wait for the wallet to complete synchronization. Open the wallet - "help" - "debug window" - "console" 2. Input the command: getblockhash block. For example, input: getblockhash 1 to get the hash value of the first block. Input the command: getblock just got the hash value. We input: getblock to find the value of TX, Here we are: we enter: getrawtransaction 1 (the space 1 above and behind should not be omitted) 5. In the information, the value value is the content of this block: 8.00000000, which is the currency quantity of the first block. This query method is common to all virtual currencies
e to the irreversibility of virtual coins, unscrupulous developers need to pre dig a large number of virtual coins as soon as possible. They have to set a large number of 1-N early blocks to implement pre digging. This is a dilemma. The author who has no pre dig has no motivation to maintain it. There is a risk that the author will cash out and smash the market maliciously if there are too many pre digs. Generally speaking, the author will use part of the pre digs for promotion and maintenance, but the pre digs generally do not exceed 2%. But in practice, many authors have done a lot of pre excavation
1. For example, Wolong, the author of Panda Coin (transaction code: PND), had a serious pre excavation. When he went public, the author smashed 18e coin directly into the market, from 200 Cong bitcoin to the price of Jicong bitcoin. At the same time, the domestic promotion QQ group was disbanded, a large number of investors were deeply locked, resulting in a very bad impact
2. For those who are lucky in disguise, e to the failure of the author's pre dig, such as moleculars (transaction code: mol), the author stole about 10 million (total 2e) after the release of the coin. At that time, it caused a big stir in the foreign Shanzhai coin forum. Some Shanzhai coin lovers directly used big computing power (51% computing power attack) to cause the currency to split, After the restart of the block, all the pre g coins were lost, resulting in that the total amount of the coin is only 1.9e, because the zero pre g coin caused by the accident aroused the interest of the majority of coin friends, and the computing power of the whole network once exceeded 200g. At present, the author's maintenance power comes from the donation and reward of fans at home and abroad, and the author's enthusiasm for coin friends is unexpected
therefore, instead of worrying about pre excavation and no pre excavation, we should pay more attention to the amount of pre excavation and the purpose of pre excavated coins. It is recommended that you do not play with more than 2% of the pre g coins. The so-called POW refers to the proof of work, that is, the proof of work. In short, it is to get rewards through calculation, and it can be calculated by mining machine or computer CPU, GPU, etc., that is the so-called mining. Investors can get it by buying it from home or digging their own mines. Relatively fair, early investors can not monopolize the quantity and price of currency. Representative currency: bitcoin, etc
the so-called POS refers to the proof of stock. In this way, currency investors can only buy from the previous home, which is similar to the pyramid style. The distribution is extremely unfair. Many currency investors get a lot of currency at the initial stage, and later can only get it from the initial investors at a high price, which leads to the monopoly of the initial investors on the currency price. Representative currency: NXT, etc
the so-called IPO is more similar to crowdfunding in the field of Shanzhai currency, that is, the author or company initiates the investment target, and domestic and foreign investors invest and obtain a certain amount of currency or options. This kind of representative currency: PTS, etc. However, e to 3I company, PTS has been delayed again and again, which has a great impact on investors' confidence
As an emerging technology, digital currency plays an important role in improving financial efficiency, promoting cross-border payment and adjusting the monetary system
All in all, China's digital currency is taking the lead in the world, and it is inevitable to promote the international market
