D. The difference between virtual currency and electronic currency

With the development of the Internet To grow, while providing a large number of free services to the majority of Internet users, we also provide various services according to the company's profit needs and the diverse needs of users.To meet the demand, various websites have launched paid services. This also promotes the creation of virtual currencies.
Many portal websites and online game operators have long begun to provide virtual currencies for use in order to provide better services. According to incomplete statistics, there are currently no fewer than 10 types of online virtual currencies (referred to as online currencies) in circulation on the market, such as Q coins, network coins, cool coins, Warcraft coins, paradise coins, Shanda (game area) coupons, etc. Taking Q Coin as an example, there are more than 200 million users. Industry insiders estimate that the domestic Internet has a virtual currency market size of several billion yuan per year and is growing at a rate of 15% to 20%.
In a market economy, demand stimulates innovation, and innovation in turn drives demand. The growing popularity of virtual currency is due to the needs of users and the innovation of enterprises. At present, there are many types of virtual currencies in China's online market, among which Tencent, relying on its huge QQ users and the maturity of the instant messaging market, also launched Q Coin in a timely manner.
It is undeniable that virtual currency allows us to feel the convenience of purchasing online services, which is an inevitable product of the development of the Internet economy. But at present, online virtual currencies have quietly transformed and formed a huge trading market.
Linton LaRouche, a famous American economist, also predicted that starting from 2050, the virtual currency of the Internet will be officially recognized to some extent and become a circulating currency. With such a large-scale market and bright prospects, many companies are already eager to occupy this market. Right now, it seems that DotNet, PAYPAL, and Tencent are in the lead.
At this stage, most electronic currencies are based on existing physical currencies (cash or deposits) and have the functions of "value scale" and "value preservation", and electronic currencies are not related to physical currencies. This is based on the prerequisite that currencies can be exchanged at a ratio of 1
:1.
As a means of payment, most electronic currencies cannot be separated from cash or deposits. They are transmitted and transferred electronically to settle claims and debts. Therefore, the function and impact of electronic money at this stage is essentially the relationship between electronic money and cash and deposits.
Currently, there are four main types of popular electronic currencies in our country.
1. Stored value card type electronic money. They generally appear in the form of magnetic cards or IC cards. In addition to commercial banks, their issuers include telecommunications departments (ordinary phone cards, IC phone cards), IC companies (Internet cards), commercial retail companies (all kinds of consumer cards), government agencies ( Internal consumption IC card) and school (campus IC card), etc. After receiving funds from customers in advance, the issuing entity issues stored-value cards of equal value, making the stored-value cards a new "deposit account" independent of bank deposits. At the same time, the stored-value card pays by deduction when customers consume, which is equivalent to paying currency in a deposit account. Deposits in stored-value cards are currently not subject to central bank reserve requirements. Therefore, stored-value cards can reduce the need for cash and current savings.
2. Credit card application typeElectronic money. Refers to credit cards or quasi-credit cards issued by issuers such as commercial banks and credit card companies. You can borrow money for consumption within the credit limit specified by the issuer, and then repay it within the specified time. The widespread use of credit cards can expand consumer credit and affect the money supply.
3. Deposit utilization electronic currency. Mainly include debit cards, electronic checks, etc., which are used to electronically withdraw cash, transfer settlement, and transfer funds from bank deposits. The widespread use of this type of electronic payment method can reduce the cost of consumers going to and from the bank, resulting in a reduction in cash demand balance and speeding up the circulation of money.
4. Cash simulation electronic currency. There are two main types: one is electronic cash that is used based on the Internet network environment and stores binary data representing monetary value in the hard drive of a microcomputer terminal; the other is electronic cash that stores the monetary value in an IC card and can be circulated independently of the bank payment system. electronic wallet. This type of electronic currency has the anonymity of cash, can be used for personal payments, and can be changed hands multiple times. It was developed with the purpose of replacing physical cash. The expanded use of this type of electronic currency can affect the currency issuance mechanism, reduce the seigniorage revenue of the central bank, and reduce the scale of the central bank's assets and liabilities.
