1. At present, digital currency is more like an investment. Due to the lack of strong guarantee institutions to maintain its price stability, its role as a measure of value has not yet emerged, and it cannot be used as a means of payment. As an investment product, the development of digital currency cannot be separated from trading platforms, operating companies and investors.

Trading platforms play the role of trading agents, and some play the role of market makers. The profits of these trading platforms come from the current fees and premium income of investors trading or holding digital currency.

1. Investors need to register their accounts first, 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 trading requests according to the rules and start matching. If it meets the requirements, the transaction is completed.

4. Due to the difference between the buying and selling volumes submitted by users, the buying and selling request can be partially executed.

Take RBM operated by professional operation company opencoin as an example: Ripple protocol was originally designed based on payment method, and its design idea is based on acquaintance relationship network and trust chain. Use Ripple network for remittance or loan, provided that the payee and payer are friends or have the same friends. Otherwise, a trust chain cannot be established between users and other users, and transmission cannot be carried out.

Second, the characteristics of digital currency:

1. Low transaction cost

Compared with the traditional way of bank transfer and remittance, the transaction in digital currency does not need to be paid to a third party, and its transaction cost is lower, especially compared with the cross-border payment that provides high fees to payment service providers.

2. The transaction speed is fast

The blockchain technology adopted by digital currency has the characteristics of decentralization, and it does not need any centralized institution like clearing center to process data, so the transaction processing speed is faster.

3. Highly anonymous

In addition to realizing peer-to-peer transactions in the physical form of money without intermediary participation, one advantage of digital currency compared with other electronic payment methods is that it supports remote peer-to-peer payment without any trusted third party as an intermediary.
