What are the benefits of virtual currency trading volume
(1) buying and selling stocks are based on hands, with 100 shares in each hand. Each transaction starts with one hand. If the share you want to buy is 1 yuan per share, you need 100 yuan to buy one hand. If the share is 10 yuan, you need 1000 yuan to buy one hand. Transactions of more than 100 shares must be integral multiples of 100 shares. In practice, every time you buy a stock, you must buy more than or equal to one hand, and there is no integer limit when you sell a stock
one hand stock is the minimum trading limit of a stock market, and the regulations of each market are different. In the regulations of Shanghai Stock Exchange and Shenzhen Stock Exchange, one hand stock is equal to 100 shares
(2) generally speaking, the market volume refers to the transaction amount. Explain the market activity and capital scale. The trading volume and turnover amount are expressed by the following formula: turnover volume * turnover price = turnover amount
(3) turnover rate, that is, the proportion of trading volume in the total circulating share capital. Turnover rate is a percentage of the turnover of a stock in a year. According to the nature of the sample population, there are different indicator types, such as the total turnover rate of all listed stocks in the exchange, the turnover rate based on the number of a single stock issued, and the turnover rate based on the portfolio held by an institution
there are different algorithms, which roughly calculate the volume per minute of the day's closed period. Then multiply this value by the number of minutes of the day. Some added the volume per minute of the previous trading days as a reconciliation, forecast closer
it has the meaning of estimation. You can directly read the volume of today's large volume or small volume on the trading volume chart,
The role of digital currency:
1. First of all, the central bank's digital currency can provide a huge data base for monetary policy and macro Prudential policy, so that the regulatory authorities can collect real-time trading books of different frequency and different institutions according to their needs, and it is complete and real. This information advantage can help the central bank use policy tools more accurately and flexibly
Secondly, the central bank's digital currency technology can track the flow of funds and help the regulatory authorities to comprehensively monitor and assess financial risks. Finally, the central bank's digital money technology is concive to the transmission of interest rate of monetary policy. Digital currency technology supports "point-to-point" payment and settlement, which can improve the liquidity of market participants. Only the digital currency of the central bank, which is generally accepted by the whole society, can radiate this advantage to the participants of different financial markets, so as to improve the liquidity of financial markets. This will make the term structure of interest rate smoother and the transmission mechanism of interest rate smoother 
extended data:
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: because it comes from some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
the value of virtual currency is that it is based on blockchain technology, has high security, and is suitable for being a decentralized currency after a period of depression, the price of bitcoin has recovered again recently, standing at the price of US $40000, which is the biggest rebound in the price of bitcoin since this month. In fact, since last year, the bitcoin market has ushered in a wave of rising prices. Some analysts say that the main driving force for the rise is that large financial institutions begin to enter the market and take bitcoin as a part of their asset allocation. Some well-known investment companies and fund companies, and even conservative insurance companies regard bitcoin as one of the investment options
after the release of the report "bitcoin soaring or hidden" exchange factor "vigilance policy raid and market risk" on January 5, the fermentation of a series of events such as the central bank's interview with bitcoin platform and the platform's self rectification not only fulfilled our previous prediction, but also showed that the further attention of the regulatory authorities is promoting bitcoin into a relatively strong regulatory cycle
however, considering that bitcoin is a decentralized currency based on international blockchain technology, and its stability has a gold like rigid guarantee, although regulatory policies will have a negative impact on the ecology of bitcoin in the short term, the development of bitcoin in the medium and long term is still worth looking forward to at a time when inflation expectations become more obvious
domestic applied digital currency is also very popular, such as Puyin, which issues 1 billion Tibetan tea as credit endorsement. The identification, evaluation, right confirmation and other related information of Tibetan tea assets will be recorded on the blockchain through encryption technology, so that the asset related information will be more open and transparent.
Segregated witness is a bitcoin scalability scheme proposed by Pieter wuille, one of the maintainers of bitcoin core. In short, this scheme is to change the transaction structure of bitcoin, take out the signed part of the transaction and put it into another structure called witness
this kind of technology is reliable. The reason why the Chinese community opposes it is actually the core, not this technology. This technology is still relatively good, but the bitcoin community does not see the decline of the main chain. Lightning network intelligence plays an auxiliary role instead of replacing the main chain. Therefore, most people insist on the expansion of the main chain
