Must webcast use virtual currency
virtual currency and electronic currency are not the same concept
the definition of e-money is to convert a certain amount of cash or deposit from the issuer and obtain data representing the same amount. By using some electronic methods, the data can be directly transferred to the payment object, so as to pay off the debt. E-money means that consumers pay traditional money to issuers of e-money, and issuers store legal money of equal value with traditional money in electronic devices held by consumers
electronic currency is the electronization of the legal tender, including our common bank cards, Internet banking, electronic cash, etc., as well as the third party payment developed in recent years, such as Alipay, fortune paid and so on. No matter what form these electronic currencies are and through which institutions they circulate, their original source is the legal money issued by the central bank
but virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. For example, Tencent Q currency and other game currency, such virtual currency is mainly limited to circulation in a specific virtual environment. After the emergence of bitcoin, through the blockchain technology to better solve the problem of decentralization, distrust, to achieve global circulation, is sought after in the world. Electronic currency and virtual currency are collectively referred to as digital currency
bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system

The equipment is composed of main shaft, feeding port, breaking plate, material retaining cone, wind wheel, inner cone shell, outer cone shell, etc. The main shaft is fixed on the top cover plate of the outer cone shell through the shaft sleeve, and is driven to rotate by the external power. The main shaft is used to hang the dispersing plate and the wind wheel in turn, and the material retaining cone is fixed between the dispersing plate and the wind wheel through the outer cone shell. In addition, there are impact plate, hot air inlet and outlet. When in use, the material is fed by the feeding port and falls on the dispersing plate. Due to the high-speed rotation of the spindle, the dispersing plate rotates at a high speed, so that the material falling on the dispersing plate flies out at a high speed and is crushed after hitting the impact plate. Because the process of dispersion is continuous, the material rebounded from the impact plate is fully crushed by the subsequent material. When the crushed material is introced into the wind power separation area of the wind wheel through the material retaining cone, the movement state of the coarse powder changes little, falls into the inner conical shell, and is discharged through the coarse powder discharge port, while the movement state of the fine powder changes greatly. Under the action of the wind force, the coarse powder deviates greatly and falls into the inner conical shell and the outer conical shell{ RRRRR}
virtual currency can be roughly divided into three categories:
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Wright currency (LTC), Fuyuan currency (FTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.
for ordinary people, the threshold to enter the live broadcasting instry is really very low. They only need a computer and an account to broadcast live, and mobile phone software can realize live broadcasting anytime and anywhere
under the "temptation" of high income, some young people are flocking to the webcast instry. Is this a "sugar coated bullet" with high salary, or is it true
with this doubt, the reporter of daily economic news consulted the person in charge of Qiqi interactive video operation, who has many years of live video experience. The person in charge said that there is no big problem with the monthly income of the anchor of the general new platform of 5000 to 8000. After two months of broadcasting, the new anchor will broadcast live for 3-5 hours a day, with a monthly income of 10000-20000 yuan; The average number of fans of medium anchor is about 300000 to 500000, and the monthly income can reach 100000 to 200000; The high-quality anchor with 500000-1 million fans can earn 300000-500000 a month
as for the source of high income, Yin Hong (a pseudonym) of an online live video company told the daily economic news that in addition to the base salary, the vast majority of an anchor's income comes from the virtual currency given by fans
according to Yin Hong, fans can recharge cash to get virtual currency, and then they can buy gifts for their favorite anchor. After receiving the virtual currency, the platform shares it with the anchor and brokerage companies“ We have the same distribution of anchors of different levels in Cheng, which is 32%, the brokerage company is 18%, and the rest is owned by the platform. "
brokerage companies participate in profit sharing because larger live broadcasting platforms often cooperate directly with brokerage companies, which are responsible for recruiting anchors or artists, and then providing suitable candidates to live broadcasting platforms for cooperation
"our platform cooperates with more than 600 brokerage companies to provide anchor." The person in charge of Qiqi interactive video operation said.
Sample standard deviation 
extended data:
standard deviation is also called standard deviation. Standard deviation describes the average of the distance (deviation) of each data from the average, which is the square root of the sum of the squares of the deviations σ Expression
The standard deviation is the arithmetic square root of variance. The standard deviation can reflect the dispersion of a data set. The smaller the standard deviation is, the less these values deviate from the average value, and vice versa The standard deviation ofcan be measured by the multiple relationship between the standard deviation and the average value. The standard deviation of two datasets with the same mean may not be the same
for example, six students in group A and group B took the same language test. The scores in group A were 95, 85, 75, 65, 55 and 45, while those in group B were 73, 72, 71, 69, 68 and 67
the average of the two groups is 70, but the standard deviation of group A should be 18.708 points, the standard deviation of group B should be 2.366 points, indicating that the gap between students in group A is much larger than that between students in group B

standard deviation can reflect the degree of dispersion of a data set. The smaller the standard deviation is, the less these values deviate from the average value, and vice versa. The size of standard deviation can be measured by the multiple relationship between standard deviation and average value. The standard deviation of two datasets with the same mean may not be the same

The average of the two groups is 70, but the standard deviation of group A should be 17.078, and the standard deviation of group B should be 2.160, indicating that the gap between students in group A is much larger than that between students in group B
