Digital currency cannot be exchanged for paper currency

1. Can also be used, there is a digital currency does not mean that the RMB can not be used

2. After the digital currency is sold, it is generally universal usdt, or OTC, which can be directly converted into legal currency, that is, RMB, which is not difficult to operate.

3. Digital currency will be a supplement to the currency series, completing the same payment and clearing functions as paper money. Of course, digital currency has its unique advantages, and new currency application functions may appear in the future. Compared with paper money, digital money is more convenient and easier to store, but when it comes to replacement, it is not necessarily possible, at least in the short term.

4. Maybe it's burning engine oil, otherwise it won't be short of engine oil. If you add it all the time, this machine can't be used. So the cost is too high. It's definitely not suitable.

5. There is no need to exchange it. It is the digital form of RMB. It's legal tender. It's compulsory circulation.

6. If there is a sign, who will sell bitcoin? If everyone knows in advance, they will be millionaires.

7. Edison (1847-1931) was a famous American inventor. He was diligent, studious, thoughtful and hardworking all his life. At the age of 75, he also went to the laboratory on time every day to check in for work. For decades, he worked for more than ten hours every day and read for three to five hours in his study at night. If we calculate by the activity time of ordinary people's life, his life has been doubled. So Edison, on his 79th birthday, said to people with pride, I'm 135 years old. He lived to be 84 years old. He made 1100 inventions in his life. His greatest contributions were the invention of phonograph and automatic telegraph, the experiment and improvement of incandescent lamp and telephone. Edison began to study electric lamps in his early twenties. It took him more than 10 years. He used thousands of different materials, such as bamboo, cotton, graphite, tantalum, and so on, as filament materials to carry out experiments. He often reached the top of the sky. Once, he and his assistants worked continuously for five days and nights. In 1879, Edison used carbon filament as incandescent filament and ignited it for 40 hours. Because the surface of carbon fiber is porous, brittle and low strength. It was soon replaced by tungsten wire< In 1883, Edison discovered the phenomenon of hot electron emission, also known as "Edison effect", that is, some electrons or ions near the metal surface get enough kinetic energy e to the high temperature, so as to overcome the binding of the surface and escape from the metal. Edison effect is very important for the operation of all vacuum tubes. The cathode, as the emitting surface, is often coated with alkaline earth metal oxide to facilitate electron emission, and heated by electric current to maintain high temperature< In 1900, Edison invented the iron nickel battery, which is an alkaline battery with electromotive force of about 1.3-1.4 V, long service life and low efficiency.

8. In China's credit monetary system, if the amount of money issued by the central bank is greater than the amount of money needed in circulation, it will cause inflation, and the currency will depreciate relative to other single currencies, that is, money is worthless. The inflation of banknotes as precious metal tokens is explained as follows:
inflation generally refers to the devaluation and price rise of banknotes caused by the issue of banknotes exceeding the amount of money actually needed in commodity circulation. Its essence is that the total social demand is greater than the total social supply< In modern economics, inflation means the rise of the overall price level. General inflation is the decline of market value or purchasing power of currency, while currency depreciation is the relative decline of currency value between two economies. The former is used to describe the national currency value, while the latter is used to describe the added value in the international market. The relationship between them is one of the controversies in economics
the circulation law of paper money shows that the circulation of paper money can not exceed the amount of gold and silver money it symbolically represents. Once it exceeds this amount, the paper money will depreciate and the price will rise, resulting in inflation. Inflation can only occur under the condition of paper currency circulation, but not under the condition of gold and silver currency circulation. Because gold and silver money has its own value, as a means of storage, it can spontaneously adjust the amount of money in circulation and make it adapt to the amount of money needed for commodity circulation. Under the condition of paper currency circulation, because paper currency itself has no value, it is only a symbol of gold and silver currency, and can not be used as a storage means. Therefore, if the circulation of paper currency exceeds the quantity needed for commodity circulation, it will depreciate

for example, if the amount of gold and silver currency needed in commodity circulation remains unchanged, and the amount of paper money issued exceeds twice the amount of gold and silver currency, the unit paper money can only represent 1 / 2 of the value of the unit gold and silver currency. In this case, if the price is measured by paper money, the price will double, which is commonly known as currency devaluation. At this time, the amount of paper money in circulation is double that of gold and silver money needed in circulation, which is inflation. In macroeconomics, inflation mainly refers to the general rise of prices and wages.

9. The impact of digital currency on paper money is inevitable, but it will not completely replace paper money. The central bank's digital currency is the digital replacement of paper money. The functions and properties of digital currency are exactly the same as paper money, but its form is digital. The central bank's digital currency DC / EP should start from M0, that is to say, it should start from the replacement of banknotes and coins in circulation by digital currency, not to replace all RMB. In fact, the balance in the commercial bank account already exists in the form of digitization, so there is no need to replace it
the current network transmission of digital RMB system (DC / EP) information is the testing content in the process of technology research and development, but it does not mean that the digital RMB is officially launched. At the current stage, the internal closed pilot test will be concted in Shenzhen, Suzhou, xiong'an, Cheng and the future Winter Olympic Games
digital currency based on blockchain has al characteristics. On the one hand, it can replace the existing inefficient cross-border payment and settlement system and promote the development of trade; On the other hand, because of its decentralized, autonomous and anonymous nature, it is easy to cause economic fluctuations and encourage criminal activities
