Bitcoin virus makers
Once the computer is infected with this bitcoin blackmail virus, all the file data on the computer will be forcibly encrypted. If it is not delivered in the form of bitcoin to the virus maker & lt; Ransom;, Then these files can't be decrypted and retrieved. Even if the ransom is paid this time, they may be decrypted next time; Patronize & quot& mdash;& mdash; That is to say, this virus is very important to & lt; Pay attention to data & quot; It's hard to estimate the harm that can be caused by the users, especially the enterprise users

Hayek studied business cycle theory and monetary theory with his teacher Mises early in his academic career. In 1931, he published "price and proction". Because the proposition in the book is contrary to Keynes's "on money" published a year ago, they launched a debate
The most typical example of 
is gold and silver. For a long time, gold and silver were the common currency in the world. The hard currency of trade in all countries did not belong to any one country. Even in the era of gold standard, the state issues legal paper money, but legal paper money is still anchored by the free competition of gold. Gold circulates freely in the world and is more rigid than paper money
There are at least three reasons that lead to the existence of a large number of competitive currencies:one is the existence of multi-level market, because the metal currency is not easy to cut, super zero denomination currency and silver currency coexist
In the 18th and 19th centuries, there were long-standing high-ranking gold coins in Bangladesh, such as mulu, Sika rupee, middle akut rupee, and low ranking copper coins and BEIBI coins. Because silver coins are not easy to cut, a large number of shell coins with zero denomination are needed in remote areas and small exchangethis situation existed for a long time in ancient China, and the copper coin standard lasted for more than a thousand years in ancient China, but the iron coin also circulated for a long time (such as the Song Dynasty), and the face value of iron coin was smaller than that of copper coin. In the Qing Dynasty, with the discovery of Potosi silver mine in South America, a large number of silver coins flowed into China. Around 1730, the use of silver and money accounted for half of the transactions. Compared with copper coin, silver coin has a larger denomination, which is convenient for large transaction and solves the problem that copper coin is not easy to transport
The second is seasonal deflation, and private coins balance market demandin the agricultural era, the transaction volume of agricultural procts accounted for a large proportion, and a large amount of money was used for agricultural procts transaction. However, agricultural procts have obvious seasonality, and the transportation and supply of metal money is extremely inconvenient, so the problem of insufficient money often appears in the harvest season. In his book, Professor Kuroda cites the example of Quanzhou, Fujian Province, China in 1606. The original inventory management money could not meet the rice trade, so the private money was imported to meet the market demand to balance supply and demand. This kind of situation happens every year in China. Every year, it is the peak of money demand near the Spring Festival. The central bank will release part of liquidity to balance supply and demand
Thirdly, metal currency is a kind of deflation currency, which circulates a variety of currencies in regional and specific areas In his book, Professor Kuroda cites Nadina Jebel's case, "the transactions of grains such as rice are used for sonoto silver coins, the transactions of oils and fats are only used for French akote rupees or British akote rupees, and the transactions of flax are only used for French akote rupees." At the beginning of the 20th century, in China, all kinds of silver coins were circulated in Jiujiang, Jiangxi Province. Mexican silver coins were used for the export of tea and porcelain procts in Shanghai, and silver coins issued locally in Jiangsu Province were used for the trade of local markets such as tobacco or beans. There are also silver bills used in Shanxi business circle, and various copper coins used in the coin community around the China Sea, including Japan, North Korea, Southeast Asia and other countriesthe problems of metal currency in multi-level market, seasonal deflation, regionality and specific fields do not exist in today's credit currency era. Many of the competitive currencies listed by Professor Kuroda also disappeared in the globalization of silver coins and the legal tender system
therefore, the monetary pattern of countries in the world we see today is one country one currency, which is legally issued by the state monopoly
