Virtual currency rating full version

1.

Weiss ratings, an asset rating agency, has released the world's first rating report on 74 virtual currencies, according to finance magnates. Among them, Ethernet is the highest rated and bitcoin is in the mid stream

The rating criteria of

Weiss ratings include risk, reward, technology and social acceptance, which are used to compare computer models and get the final results. Weiss ratings also said in a statement on Wednesday that its website had been attacked by hackers from South Korea in an attempt to block the release of the rating report

According to Martin D. Weiss, founder of Weiss ratings, the price trend of many virtual currencies is relatively low, and there is a risk that they will come to nothing. At present, the virtual money market is still relatively complex. The market value of global virtual money is more than half a trillion US dollars, but it is not regulated. On the technical level, blockchain technology also makes it difficult for regulators to legislate in the traditional way of assets

Coin rating is the process of determining the degree of old and new of a coin, which is a rather subjective process. Traditionally, people often use vague words such as "good" and "good" to describe the appearance of a coin

because the old and new degree of coins has a great influence on the value of currency, the simple lack of standardized description of coins is obviously not concive to the market transaction of collected coins. After long-term development, people have graally established a set of relatively objective and standardized coin rating standards, which originated in the United States and has been widely promoted all over the world

I. China's first series of rated banknotes. China's first full set of RMB rated banknotes

since 1948, the people's Bank of China issued the first set of RMB, so far it has issued five sets of RMB. The fourth set of graded banknotes is the first series of graded banknotes since the founding of new China. There are nine denominations ranging from 10 cents to 100 yuan

At the same time, the fourth set of RMB rated banknotes is the only collection of banknotes issued in the form of rating, which is the most authoritative and influential variety of banknotes at present, and has extraordinary significance in the history of Chinese currency issuance

Second, to commemorate the 30th anniversary of the circulation of the fourth set of RMB

it has been 30 years since the fourth set of RMB came out. With the improvement of people's living standards, the use of small banknotes has decreased, and the loss rate is higher. However, e to the accelerated use of large banknotes, the wear and tear is serious, and new banknotes or banknotes with good quality are rare

and the fourth set of RMB rated banknote collection conforms to the current situation and solves the huge market demand of less genuine and better procts. The people's Bank of China specially issues the fourth set of RMB rated banknote collection to commemorate the 30th anniversary of RMB circulation

A note or coin that has been appraised by a third-party coin appraisal company is called a rating note. It means that the rating company will give the coin a score, which is the rating in the rating. Generally, the one with a higher score will be worth less than the one with the same score. The reason why the price is higher than that of bare money is that the rating costs money, time cost and the risk of losing and damaging the express delivery

the biggest advantage of rating currency over bare currency is that there is no need to worry about the authenticity of the currency (as long as the rating company is reliable) as long as it can enter the shell, the rating company will be responsible for the authenticity of the coin. If the appraisers take the fake procts seriously into the shell, the rating company will be responsible for it and pay the price of the same kind of genuine procts. Secondly, the coins are sealed and sealed, which can relatively eliminate the damage of natural factors such as air and moisture, making the coins easier to keep. Moreover, because the rating coin has a shell outside, it can be taken directly by hand without gloves or tweezers, which is convenient to play

however, there is a misunderstanding that highly rated banknotes must be perfect, which is wrong, such as yellow spots on banknotes, binding marks and stapler pinholes (in the past, central banks in India, Pakistan and other countries used staplers to bind banknotes, counting 20 banknotes and then stapling them together, So it's hard to find bills in some currencies that don't have pinholes. Many rating companies will ignore these flaws. Especially the pursuit of flawless, choose high cents also want to look carefully

moreover, many rating companies are only responsible for the authenticity of banknotes, but they don't specially look at whether it is a change number currency (for example, several 8, several 9). Therefore, the number playing friends also need to look at whether it is a change number currency

for coins, it's better to pass the X-ray machine if conditions permit, because some coins are repaired (especially copper coins). You can't see them by naked eye, only the photo can find the repair.

8. In the United States, the earlier grading methods also used vague words to classify coins. In the later stage, the more perfect letter grading system mainly included poor (poor or PO), fair (fair or FR), nearly good (almost good or Ag), good (good or G), very good (very good or VG), fine (fine or F), very fine (very
fine or VF), extra fine (XF), very fine (VF) and so on Almost no circulation (almost
uncoirculated or Au), uncoirculated or UC, and brilliant
uncoirculated or BU)
in the 1950s, William H. Sheldon first proposed Sheldon standard in his book. This standard uses numbers to represent the old and new coins, and the range of numbers is 1-70< In 1986, PCGs, a modern professional coin appraisal and rating company, was founded in the United States. The company combines the above two rating methods, and uses letters and numbers to rate the old and new coins, including
BS-1, FR-2, ag-3, G-4, G-6, vg-8, vg-10, F-12, F-15, vf-20, vf-25, vf-30, vf-35, XF -
40, xf-45, au-50, au-53, au-55, au-58, ms-60, ms-61, ms-62, ms-63, ms-64, ms-65, MS -
66, ms-67 Ms-68, ms-69 and ms-70

therefore, xf45 is a 45 score of special exquisite level, while au50 is a 50 score that has hardly been circulated. Naturally, you will know which one is better.
