Digital currency (electronic money or electronic money) is a digital currency (different from paper money, coins and other physical objects). It shows properties similar to physical currency, but it can allow instant transactions and borderless ownership transfer. Examples include virtual currency, cryptocurrency and currency (including digital base currency) issued by the central bank for bookkeeping in computer databases. Like traditional currencies, these currencies may be used to buy physical goods and services, but they may also be restricted in some communities (such as online games).

Digital currency uses relevant platforms for payment:

1. Investors must first register their accounts, and at the same time obtain digital currency accounts and US dollars or other foreign exchange accounts.

2. Users can buy and sell digital currency with the money in their cash accounts, just like buying and selling stocks and futures.

3. The trading platform will sort the buying requests and selling requests according to the rules and start matching. If they meet the requirements, the transaction is completed.

4. Due to the difference between the purchase and sale quantities submitted by users, the purchase or sale request may be partially executed.

1. Cryptographic currency refers to digital currency, which uses cryptographic algorithms and does not depend on anything in kind. Now it refers to English Cryptocurrency (referring to the digital currency of Bitcoin, including Bitcoin).

Such as bitcoin, Litecoin, bitcoin stocks, etc. Is digital currency created, distributed and maintained by cryptography and authentication technology? The characteristic of cryptocurrency is that it uses peer-to-peer technology, and everyone can issue it.

Cryptographic currency can be divided into public mining cipher digital currency (represented by Bitcoin) and distributed cipher digital currency.

Two. Since 200 1, the EU has implemented the electronic money directive "on accepting, tracking and prudently supervising the business of electronic money institutions", which was last revised in 2009. Since the 2007 EU Payment Service Directive requires the merger of payment institutions and electronic money institutions, people have doubts about the true nature of electronic money in the EU. This merger may mean that electronic money has the same nature as bank money or demand deposits.

In the United States, for wholesale transactions, electronic money is governed by Article 4A of the Uniform Commercial Code, and for consumer transactions, it is governed by the Electronic Fund Transfer Law. The responsibilities of suppliers and consumers are bound by laws and regulations.
