digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and password currency belong to digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

Electronic money means that a certain amount of cash or deposit is exchanged from the issuer and the data representing the same amount is obtained. By using some electronic methods, the data is directly transferred to the payment object, so that the debt can be paid off. Strictly speaking, consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in the electronic devices held by consumers in electronic form. In short, when we deposit money into our bank account, there will be an extra number in the bank account, which means how much money we have saved. In this process, we give the banknotes in our hands to the bank, and the bank adds a number to our bank card, which is our electronic currencyfeatures:
< UL >e-money and paper money (or physical money) can be easily converted to each other
the data of electronic currency corresponds to the same amount of physical currency
we need to pay physical money to the issuers of e-money (banks and other financial institutions) in order to exchange for the same amount of e-money
3. The similarity between digital currency and electronic currency: both exist in the form of electronic data
The differences between digital currency and electronic currency are as follows:electronic currency has an issuing institution, and the corresponding amount of physical currency in the institution can be exchanged with physical currency; However, digital currency has no specific issuing institution (decentralization) and can only exist in network data
at present, there is no international consensus on whether digital currency is a currency or not, so in China, the main form of digital currency is "investment proct", which is a rather risky investment proct, and only a few businesses are willing to accept digital currency consumption; Of course, some countries (Germany, etc.) have officially recognized the currency status of digital currency
