The idea of digital currency

1. 1. Low transaction cost
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to a third party, and its transaction cost is lower, especially compared with cross-border payment which provides high service charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency over other electronic payment methods is that it supports remote point-to-point payment, It doesn't need any trusted third party as an intermediary, and the two sides of the transaction can complete the transaction in a completely strange situation without mutual trust. Therefore, it has higher anonymity and can protect the privacy of traders, but it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities

2. In short, virtual currency, also known as cryptocurrency, is issued and circulated on the Internet and mainly traded through exchanges. Because it runs on the blockchain, every transaction on the chain is semi anonymous and tamperable, so it ensures the circulation and a certain degree of security. Mainstream digital currencies include bitcoin, Ethereum and Leyte. Digital currency is inseparable from blockchain technology. The core idea of the latter is to ensure that all nodes have a consensus on a transaction through transaction broadcast and irrelevant node confirmation. Once the consensus is formed, transaction confirmation, block excavation and reward will follow. This reward is digital currency. If digital currency wants to have value, it can't do without people's recognition of its value. The more recognition, the more people want to have it, and the exchange came into being. If it's Xiao, it's not recommended to go to big exchanges (currency security, currency, OK) to play contract leverage. You can go to small exchanges to practice, such as currency easy, etc. You can also learn about the coin circle information. The development of the whole coin circle changes every day, very fast
there is no price limit for P.S. digital currency trading, so investment should be cautious!

4. Credit endorsement by the state has the function of value anchoring and credit creation, which will have a substantial effect on the economy. Legal digital currency, like paper money, is essentially pure credit currency. However, digital currency can further rece operating costs, and can be applied in a wider range of areas with higher efficiency
"the emergence of digital currency follows the inevitable law of currency evolution, and is also the inevitable result of the development of science and technology. From the perspective of historical process, the carrier of currency has evolved from shellfish and precious metals to paper money, and then to the popular third-party payment electronic currency in modern society
in essence, they are pursuing the convenience and low cost of transaction, and this trend continues to develop, and the manifestation in the future society is digital currency. The first thing to solve is the technical barriers, although today's blockchain is regarded as the Internet of the 1990s, and its future is limitless. But it is not mature enough to support the huge payment system. At the same time, the issuance of legal digital currency will greatly increase the number of point-to-point transactions, bypass the original regulatory system to a certain extent, and easily facilitate illegal transactions. As digital currency makes it very convenient to convert deposits into cash, financial panic and financial risk will accelerate the spread once they occur, which increases the difficulty of supervision. In addition, in the process of using legal digital currency, a large number of user data and transaction information will be obtained. How to store and manage these data to prevent the disclosure and illegal use of user information is also an important challenge.
