When digital currency comes, will cash become invalid

1. Taking the present level of science and technology as an example, if the level of science and technology and humanistic quality have reached a certain height, then the social credit system will replace money. Whether it's cash or electronic money

we hope to adopt it.

2. In theory, the central bank issues digital currency to replace paper money. However, this process is very slow, because the development of various regions in China is seriously unbalanced, and the acceptance of digital currency is also different. The digital currency trial run by the central bank is only applied to the bill market
in the future, there may be many digital currencies in China, and each digital currency will have its own application. For example, Puyin is a very interesting digital currency, which corresponds to the assets related to tea.

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

4. In theory, all the money in circulation now will disappear over time. Because, the existing currency will graally not adapt to the needs of social development and graally be eliminated, just as now the third-party payment has begun to replace the trend of cash transactions. After the degree of economic development reaches a certain level and the infrastructure is perfect enough, paperless transaction will become a reality
the central bank has made it clear that it will issue digital currency, which has the function of legal currency. The token issued by European crowdfunding platform for crowdfunding projects only exists as an asset certificate, which can be traded in the market and the exit mechanism is more flexible; Of course, the digital currency launched by some platforms is used as platform points.

5. In order to prove time and ensure the security of the whole network
without this calculation, the whole system is not secure, so these seemingly meaningless calculations are to ensure everyone's security

6. This is your ignorance. The game is not just boring like a legend. You can brush the monster, brush the money and brush the equipment. In eve, the reputation you win by your mission, and the wealth and social status you accumulate are the capital you show off. What he builds is an imperial society with assets first. You can be a scientist, diplomat, army commander, engineer, etc. without occupation restrictions, Just like you are a free man in reality

7. In general, the choice of professional platform is very reliable, such as NB cloud mining, which is a very professional mining platform, subordinate to Nantong jueson network technology.. If there's anything you don't understand, ask me again
