Bitcoin is poison
bitcoin is a fraud, so we must be cautious in investment and financial management
even if it is called "hard currency", the price of gold will not only rise but not fall. There is no bubble in gold, but the price is too high, there is a bubble, and the bubble will eventually burst, such as virtual currency such as bitcoin. The more general virtual currencies, the closer bitcoin's value is to zero
this kind of currency, which is a purely calculated digital symbol, has no asset support, no financial revenue and expenditure, no cash reserve and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is a pile of beautiful printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky
the people's Bank of China and other departments issued a document to severely punish the above-mentioned behaviors, making it clear that token trading is not protected by law. With some virtual currency trading platforms turning to overseas, speculative money speculation has also turned to "underground". In the face of continuous renovation, on the basis of continuous strict supervision, government departments should constantly upgrade the means and ability of supervision, and continue to increase publicity and crackdown on popular science, so as to avoid the masses being deceived
extended information:
investing in virtual currency is more of a kind of speculation. Investors should strengthen their risk prevention awareness and identification ability. Without confirming the identity of the other party, they should not be involved in money transactions, trust low-risk and high return investment procts, especially not join the investment and financing group without verification, These are often well-designed traps by telecommunication network fraudsters
it's better to purchase the investment and financial management accompanied by the children, and learn from the official and authoritative channels, and report to the police in time when they are found to be cheated. Properly protect all kinds of account password, identity information, etc., don't tell others easily. Any reference to the need for transfer and remittance should arouse high vigilance and consult with trusted acquaintances

What's more terrible is that unlike most malicious programs, this program can replicate and spread on its own in the network, and most of the current viruses still need to rely on the successful users to spread by cheating them to click the attachment with the attack code
the attack has affected 99 countries and as many as 75000 computers, but because the virus uses anonymous network and bitcoin anonymous transaction to obtain ransom, it is very difficult to track and locate the originator of the virus

Bitcoin investment is inherently risky. It's like gambling. There are losers and winners. When it goes up, it's a sudden wealth. When it goes down, it's a poison that will kill you. To put it bluntly, in terms of real bitcoin investment, the real money makers are the big guys. At the peak of bitcoin's boom, the big guys had fierce eyes, cashed in in time and made a lot of money. At that time, those without cash out were cold. This kind of gambling like way, you can't blame others for your loss. There are risks in investment, so we should be cautious when entering the market{ RRR} anyway, I dare not touch this thing, our IQ is limited. We can't play with this stuff. I'm afraid I'll have a party on the rooftop. Be careful
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
