Papers on digital currency

1. The future world will be a digital world, and money will develop from paper money in the past to digital money in the future, which is a trend. Because in order to adapt to the digital world, the future currency must also be digital. It can be predicted that digital currency will be safer, faster and more convenient in the future. Now many blockchain technology procts, although its name is what currency, but in fact it is not currency. Under the guise of digital currency investment, it is a Ponzi scheme. Even some of them don't even have blockchain technology, which is just a fake number to cheat people.

3. Currency is original.

4. 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

5. The history of money used by human beings originated in the era of barter. In the primitive society, people used barter to exchange what they needed, such as a sheep for a stone axe. But sometimes, e to the limitation of the types of goods used for exchange, we have to find a kind of goods that can be accepted by both sides of the exchange. This kind of goods is the most primitive currency. Livestock, salt, rare shells, rare bird feathers, gemstones, sand gold, stones and other items that are not easy to obtain in large quantities have been used as currency. Gold money
metal money
after years of natural elimination, in the vast majority of society, the goods used as money are graally replaced by metal. The advantage of using metal currency is that it needs to be manufactured manually, cannot be obtained from a large amount of nature, and is easy to store. Gold, silver and copper, which are rare in quantity and difficult to smelt, have graally become the main currency metals. Some countries and regions have used iron currency. In the early days, metal coins were massive, so it was necessary to test their fineness with a touchstone and weigh them at the same time. With the development of human civilization, a more complex and advanced monetary system has been graally established. People in ancient Greece, Rome and Persia made coins of uniform weight and quality. In this way, in the use of money, there is no need to weigh, there is no need to test the quality, no doubt much more convenient. These coins bear the head of the king or emperor, complicated heraldry and seal to avoid forgery. The earliest metal currency in China was copper shell of Shang Dynasty. Shang Dynasty is also called Bronze Age in Chinese history. At that time, the well-developed bronze smelting instry promoted the development of proction and the increase of trading activities. As a result, the most widely circulated shell coins at that time were inconvenient to trade e to the unstable source, so people searched for more suitable currency materials, and naturally concentrated on bronze, and bronze coins came into being. However, this kind of metal currency made of bronze is rough in making, simple in design, unfixed in shape, without unit of use, and not widely used in the market. Because of its shape is very similar to the shell as a currency, so most people call it copper shell. Gold currency
according to the analysis of archaeological materials, after the copper shell came into being, it was circulated at the same time with the shell currency. In the middle of the spring and Autumn period, the copper shell developed into a new form of currency, that is, the copper shell wrapped with gold. It was wrapped with a thin layer of gold on the surface of ordinary copper coins, which was both luxurious and wear-resistant. Copper shell is not only the earliest metal currency in China, but also the earliest metal currency in the world.

6. OK, I'll take care of it for you.

7. We have all found that most mainstream economic experts are not very clear about the comment on encrypted currencies, which is no longer what is secret. But other encryption currencies such as bitcoin and Ethernet haven not only create the biggest bubble in history, but they are neither a formal payment method nor a good way to store funds. That's what bank of America and Dr. doomsday Nouriel Roubini think. However, although traditional financial experts spend a lot of time complaining about the volatility of cryptocurrencies, which makes them unable to be used as real currencies, people can actually use them as currencies in a variety of places to buy pizzas, shoes, etc. The growth of competitive currency acceptance rate not only proves that the public is more and more familiar with cryptocurrency, but also leads to the emergence of cryptocurrency payment services customized for enterprises. For example, coinbase commerce, launched in February this year, enables merchants to accept payments in a variety of digital currencies. However, in most cases, there are still a few merchants who accept multiple cryptocurrency payments. Again, if you want to pay in only one cryptocurrency in the world, bitcoin is your best choice. But which cryptocurrency is the most useful? Well, perhaps not surprisingly, the answer is bitcoin, just because it is more widely accepted as a means of payment than any other cryptocurrency. But as the analysis shows, other currencies are increasingly accepted by retailers and companies. Given their superior scalability, they may eventually surpass bitcoin in the next few months or even years.

8. Yes, yu'ebao and bitcoin are not the same concept. One is to make full use of currency, and the other is to replace traditional currency. And there is no effective regulation, so bitcoin is bound to fail
