The difference between digital currency and traditional currency

1.

1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin

However, some digital currencies have independent issuers

The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a 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 currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency

illegal digital currency

in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life

not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence

therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing

2. Digital currency is just some virtual currency, which is different from our paper currency. It only exists in numbers, but it also plays the same role as paper currency.

even if it's live broadcasting, it's no problem. Live broadcasting is mainly about processor and memory. You can satisfy it, but you need to ensure the network speed

4. China's legal digital currency refers to digital RMB, which is issued by the people's Bank of China in the form of digital legal currency. It is operated by designated operating institutions and exchanged to the public. Based on the broad account system, it supports the loose coupling function of bank accounts, and has the same price as banknotes and coins. It has value characteristics and legal compensation, and supports controllable anonymity. There are two key points in the concept of digital RMB. One is that digital RMB is legal tender in digital form; Another point is that it is equivalent to banknotes and coins. Digital RMB is mainly positioned at M0, that is, banknotes and coins in circulation
the central bank's digital currency has national credit and is equivalent to legal currency. Its functional attributes are exactly the same as those of traditional paper currency, but it is in digital form. Digital currency is concive to recing transaction costs, improving financial efficiency, and preventing money laundering and other illegal transactions

Consumers pay traditional money to the issuers of electronic money, and the issuers store the equal value of traditional money in electronic devices held by consumers

related introction:

e-money can transfer the balance in the bank through some electronic ways, so that transactions can be carried out. The anti-counterfeiting of traditional currency depends on the specific essence, while the anti-counterfeiting of electronic currency can only be realized by electronic technology, communication technology and encryption or authentication system

extended data

in the field of modern economy, only a small part of the currency field is displayed in the form of real currency, that is, most transactions use checks or electronic currency

As far as the intrinsic commodity value of money is concerned, it is not a choice with or without two breaks, but a process of graal quantitative change. The commodity value of e-money is almost zero, that of paper money is close to zero, that of coins and copper plates is slightly higher, and that of precious metal currencies such as gold and silver is higher

this process of quantitative change reveals the unity of the essence of different forms of money, that is, as the proct of contract, the exchange value of money is agreed by contract. When the market is stable and the trust is high, people accept paper money and other nominal money. When the market is unstable and the trust is low, people tend to accept metal money

6. You're talking about the formula for calculating the mass of iron plate
in physics, mass m = density of object ρ× The volume of the object is V, so it is necessary to measure the length, width and thickness (CM) of the iron plate first, and multiply the three to get the volume in cubic centimeter. And then multiply it by the density of iron, 7.86 grams per cubic centimeter
for example, the size of iron plate is 500 * 100 * 10cm
the mass m of iron plate is: 500 * 100 * 10 * 7.86 = 3930000 g = 3930 kg = 3.93 t
