4. Legal risks faced by digital currency: (1) at the macro level, there are legal risks, systematic risks and consumer protection. At present, the legislative problems of e-commerce and e-payment have not been solved, the concept of e-currency and related provisions need to be clarified, and many laws and regulations have not been followed up. Secondly, there is a systemic risk caused by the collapse of a single issuing institution. If a certain issuing institution loses confidence in e-money e to its poor management, other e-money issuing institutions will also face run risk. Moreover, in the absence of standardized supervision, it is difficult for the public to effectively identify the qualification and credit level of issuers. How to effectively prompt risks and protect the rights and interests of the public has become a difficult problem. In addition, the concealment, rapidity and cross-border nature of Internet payment make e-money an inevitable money laundering tool for criminals 2 At the micro level, there are technical risks and credit risks in the main body of e-money issuance. The issuers of e-money in China include banks, non bank financial institutions, Internet enterprises and other enterprises.

System software or hardware failures will affect the availability of e-money. Secondly, the unreasonable structure of assets and liabilities and high concentration of investment will lead to the lack of liquidity and the risk of default. In addition, the payment and circulation of e-money rely heavily on all kinds of networks, and there are all kinds of operational risks, such as deliberate embezzlement of other people's accounts, internal crimes of issuing institutions and malicious intrusion of hackers, which will damage the interests of e-money holders. Bitcoin, Ruitai and other digital currencies are suitable.
5. In market economic activities, money not only acts as the medium of commodity circulation, but also as the representative of property, becoming the tool of credit activities. A series of economic activities related to money revenue and expenditure, such as transactions and lending, are financial activities. The earliest commodity exchange in human history is direct barter, Barter. Barter without money often takes a lot of trouble. If Party A needs Party B's goods, but Party B doesn't need Party A's goods, they can't conclude a deal. Its disadvantages become more and more obvious with the expansion of the scope of commodity exchange. 1. Money performs the function of medium of exchange. In the practice of exchange, people graally get used to using some kind of goods that are easy to be accepted by everyone as the basis of commodity exchange; Middleman;, Second, currency performs the function of valuation unit, which is to give a certain price to the commodity. There are tens of millions of commodities in the market, and the evaluation of the same commodity's utility varies greatly, Therefore, it is often difficult for people to understand the exchange ratio of various commodities, and the transaction is naturally difficult to be fair. Because the currency that can be obtained after a commodity is sold is the price of the commodity, once the commodity has formed a widely accepted price in the market transaction, people no longer need to remember the exchange ratio of various commodities one by one, As long as you look at the price, you can see at a glance. Money has gone through the evolution process from physical money to metal money, and then from metal money to paper money, Accounting currency in the form of bill and various kinds of electronic currency in recent years have replaced some paper money for circulation. Money can be easily exchanged for a variety of goods and finance at any time. Therefore, in addition to performing the functions of exchange medium and valuation unit in commodity exchange, money itself has also become the representative of property, Not only can it be stored as future purchasing power, but also it can realize value-added by transferring to others for interest. Transferring the right to use currency for a period of time is money lending activities. In the lending activities of transferring the right to use currency, the relationship between the two parties is a kind of creditor's right and debt relationship. The creditor temporarily transfers the right to use currency for a period of time, The user of money (debtor) has the obligation to return after a certain period of time and pay a certain amount of interest
