International digital currency is an alternative currency in the form of electronic money (digital currency trades through the platform of real goods and services).

The transaction flow of digital currency through the platform is as follows: 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.
