In primitive society, people exchanged livestock, salt, shells and other hard to get goods as general equivalents
in the long history, the emergence of metal currency makes the economic life achieve unprecedented prosperity. However, e to the inconvenience of carrying metal money, paper money became the mainstream form of money. With the rapid development of modern information technology, e-money has come into our life
if the evolution process from physical money to value symbol paper money is the first qualitative leap in the history of money development, then the evolution process from paper money to electronic money is the second qualitative leap in the history of money development
from the perspective of money form, physical money itself is a commodity in addition to performing monetary functions; Paper money is a symbolic tool of value for commodity exchange and a credit currency; Electronic currency is the proct of highly developed Internet economy and continuous progress of bank payment and settlement technology.

using virtual currency to purchase virtual procts and services can only be within the scope specified and allowed by the issuer of virtual currency (Internet operator), and the size of this scope depends on the number of virtual procts and services. If the virtual procts and services provided by the website are large enough, the scope of virtual currency will be large
the currency value of virtual currency depends on the pricing of virtual currency by issuers. When no currency can communicate between virtual cyberspace and reality, the pricing of procts and services is still based on real RMB. That is to say, when issuers of virtual currency price their own virtual currency, they should first convert the price of virtual currency based on RMB
