Rating of virtual currency

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

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
