WorldCom virtual currency

1.

Some virtual currencies are illegal in China. Chinese laws prohibit virtual currencies. The only legal currency in China is RMB. Since the people's Republic of China issued RMB, it has lasted 71 years. With the development of economic construction and the needs of people's life, it has graally improved and improved. So far, it has issued five sets of RMB, forming a multi variety and multi series monetary system of paper money and metal money, ordinary commemorative money and precious metal commemorative money

except for 1,2,5 fen coins, the first, second and third sets of RMB have been withdrawn from circulation, and the fourth set of RMB has been suspended from circulation since May 1, 2018 (except 1 jiao, 5 jiao notes and 5 jiao, 1 yuan coins). The current circulation of RMB is mainly the fifth set of RMB issued in 1999

< H2 > extended information

the people's Bank of China is scheled to issue the fifth set of RMB 50 yuan, 20 yuan, 10 yuan, 1 yuan banknotes and 1 yuan, 5 jiao, 1 jiao coins of the 2019 edition from August 30, 2019. The fifth set of RMB inherits the traditional experience of China's printing technology and draws lessons from the advanced technology of foreign banknote design, which has greatly improved its anti-counterfeiting performance and currency processing modernization

Chairman Mao Zedong's head portrait in the early days of the founding of the people's Republic of China is used on the front of each denomination currency, the famous Chinese flower pattern is used on the bottom, and the main scenery pattern on the back fully shows China's long history and magnificent mountains and rivers, and carries forward China's great national culture by selecting representative patterns with national characteristics

Basic routine: the "trading market" of MLM digital currency is basically controlled by specific institutions. In order to attract investors' investment in the early stage, the currency price may be very high. Once the time is ripe, it will be sold intensively, and the price will plummet, and the investors will lose all their money

There are three characteristics of digital money MLM:

1. Digital money is a real proct, and it is highly packaged

2. The participants can get a head pulling reward, and the prize is the digital currency itself

3. Digital currency will appreciate with the increase of participants in the scam. In the cycle of digital currency appreciation, the number of participants who can obtain digital currency will also increase, and the participants, including the lowest level participants, will also gain, but in the cycle of devaluation, the bottom level participants often lose a lot

in 2017, the Internet Finance Association of Jiangsu Province issued the "internet pyramid selling identification guide", which named 26 so-called digital currencies as illegal pyramid selling projects covered or suspected to be covered with digital currency. They are: treasure money, Baichuan money, SMI, MBI, mark money, Diablo money, mmm, Fuda compound wealth management, carat money, V treasure, Vicat money, petroleum money, Huaqiang money, CB aiib Hong Kong Group, Yuansheng, Morgan money, beta money, WorldCom, u money, Jubao, 21st century fox, Wanxi wealth management, Wanfu money, Wuxing money, Yi money, Zhonghua money, etc

extended materials:

five ways to distinguish whether digital currency is pyramid selling currency:

1. Issuance mode

virtual currency does not rely on specific monetary institutions. It is proced by a large number of calculations according to specific algorithms, and is a decentralized issuance mode. Each different terminal node is responsible for maintaining the same account book, and the maintenance process is mainly to package and encrypt the transaction information by the algorithm, while the MLM currency is mainly issued by a certain organization, and the profit is made by pulling the head

2. Transaction mode

virtual currency is a kind of sporadic transaction spontaneously formed in the market, which is graally completed by a third party establishing an exchange after the scale is formed. The MLM currency is issued by an institution and traded on its own platform

3. Implementation method

virtual currency itself is an open source program, which is maintained in GitHub community. The parameters and methods of the total amount limit are shown in the open source code. The open source of MLM currency is completely ing other people's open source code, and there is no use of open source code to build programs, so its essence is controlled by the website like Q currency

4, whether to give the source code link

General decentralized digital currency will give the source code link in the prominent position of the official website, so as to show the operation mechanism of the monetary system openly and transparently. The MLM currency focuses on the transaction process of recharge purchase, but does not mention its operation mechanism. Even the website does not have the link address of the source code

5, whether the official website starts with HTTPS

generally, the addresses of the official website and trading website of decentralized digital currency start with HTTPS, and the purpose is that this kind of website can well protect the user's data from illegal theft. But the official website of MLM currency, trading website and other related websites do not start with HTTPS

3. It seems that this platform is not for foreign exchange investment. The investment projects are mainly virtual currencies, such as bitcoin or lettercoin, which were very popular before. These virtual currencies have been banned by the people's Bank of China as payment and settlement tools. Therefore, virtual currencies are not legal in China at present, so investment must be very cautious

4. WorldCom is a digital currency launched by WorldCom in 2011. WorldCom can exchange 20 kinds of currencies. WorldCom is a virtual currency with centralized issuers and special exchanges, all of which run on its website. WorldCom yuan can only be issued in the form of capital injection, transaction and exchange, rather than in the form of "mining". WorldCom provides a secure e-wallet, which allows users to transfer money to each other and payment between users and merchants.

5. It's OK to be advanced, but it's very risky to be backward. Where does 80 times dividend come from? It is inevitable that the doubling base will collapse to a certain extent. If no one joins in the follow-up, it will lose its hematopoietic function and promise that your currency is like scrap iron and has no value. Don't look at shopping now, it doesn't mean it can be used as gold. Do you believe 10000 WorldCom yuan for a urinal?

"Quantification" in daily work and life refers to the specific and clear goals or tasks that can be clearly measured. According to different situations, it shows the quantity, specific statistics, range measurement, time length and so on

the so-called quantization is to discrete the amplitude of the instantaneous value obtained by sampling, that is, to use a set of specified levels to express the instantaneous sampling value with the closest level value. The sampled image is only discretized into an array of pixels (samples) in space. The gray value of each sample is a continuous variable with infinite values, which must be transformed into a finite number of discrete values and given different codewords in order to truly become a digital image. This transformation is called quantization

extended data:

in the field of digital signal processing, quantization refers to the process of approximating the continuous value (or a large number of possible discrete values) of a signal to a finite number (or a small number) of discrete values. Quantization is mainly used in the conversion from continuous signal to digital signal. Continuous signal becomes discrete signal after sampling, and discrete signal becomes digital signal after quantization. Note that the discrete signal usually does not need to go through the quantization process, but may not be discrete in the range, or need to go through the quantization process. Signal sampling and quantization are usually implemented by ADC

extended data:

quantization level and quantization error

in the design of quantizer, the nominal amplitude is divided into several parts, called quantization level, which is generally the integer power of 2. The sample values that fall into the same level are classified and given a quantitative value. The more the quantization series, the smaller the quantization error and the better the quality. For example, an 8-bit ADC can convert an analog voltage signal within the nominal input voltage range into an 8-bit digital signal

quantization accuracy refers to the number of levels of analog signal. The higher the quantization accuracy is, the closer the collected signal is to the original signal. In radar, image processing and other technologies, after obtaining the sampling value, the data should be quantized. There is an error between the quantized value and the original sample value, which is the quantization accuracy. The higher the quantization accuracy is, the smaller the error between the quantization value and the sampling value is, and the collected data can more truly reflect the actual situation

There is quantization error in the process of

quantization. After the D / a conversion of the restored signal, this error is regenerated as noise, which is called quantization noise. Increasing quantization bits can rece the noise to an imperceptible level, but with the decrease of signal amplitude, the correlation between quantization noise and signal becomes more obvious
