practical significance
the digitalization of central bank's currency helps to optimize the central bank's monetary payment function, improve the central bank's monetary status and the effectiveness of monetary policy. The central bank's digital currency can become an interest bearing asset to meet the holder's reserve demand for safe assets, and can also become the lower limit of bank deposit interest rate
can also become a new monetary policy tool. At the same time, the central bank can affect the bank's deposit and loan interest rate by adjusting the central bank's digital currency interest rate, and help break the zero interest rate lower limit
operation system
fan Yifei, vice governor of the people's Bank of China, said in the article that the digital currency of the people's Bank of China should adopt a two-tier operation system. This model does not change the relationship between creditor's rights and debt of currency in circulation, does not change the existing money supply system and al account structure, does not constitute a competition for commercial banks' deposit currency, and does not increase commercial banks' dependence on the interbank lending market
will not affect the lending ability of commercial banks, and will not lead to the phenomenon of "financial disintermediation". At the same time, because it does not affect the existing monetary policy transmission mechanism, it will not strengthen the pro cyclical effect under the pressure environment, and it can improve the convenience and security of payment, and it also has the credit advantage of central bank endorsement
On November 9, 2019, the central bank has not launched digital currency

benefits of digital currency
the digitalization of central bank's currency helps to optimize the central bank's monetary payment function, improve the central bank's monetary status and the effectiveness of monetary policy. The central bank's digital currency can become an interest bearing asset to meet the holder's reserve demand for safe assets, and can also become the lower limit of bank deposit interest rate.

1. On the official website of the first EU launch of this currency, we can find many loopholes in the official interpretation and identification of the function and authority of onecoin. First of all, it admits that it is a counterfeit currency, but it can't find any authenticated counterfeit currency data link, The basic feature of cypyo coin is that it must be authenticated by encryption, which must be done in the process of Shanzhai coin issuing. Without authentication, it is impossible to register on the basic trading platform
2. Vicat has no "official White Paper" or "basic monetary framework criteria" as a digital currency at all. Only the so-called IPO announcement in its early stage has been found. It can be seen that this currency has not even made the basic data link estimation, let alone any so-called cryptocurrency criteria, It is only limited to the stage of crowdfunding and financing, that is to say, it takes minutes for this currency to jump
3. There may be problems with the authentication method of IPO data, because no real explanation of data and technology can be found on its page, and the so-called "unique sequence" of onecoin has not given its encryption technology announcement and technical explanation, which shows that the proction team is deliberately avoiding this problem
4. In addition, there is a big logic error in the transaction authority and transaction authentication mechanism. First of all, although virtual currency transactions can be concted through the cloud data stream of the web page, the encryption and authentication mechanism must display the address of each transaction order, that is, the user name of the so-called transfer wallet, and the user's sequence explanation column, But we can see that this authentication mechanism is not available in the whole official transaction process. It can be seen that this is not the right way of transaction authentication, and it may be direct vicious financing.
Vicat can't be compared with bitcoin, Ruitai, Laite and other digital currencies. Now, there seems to be a problem.
all under the banner of digital currency,
but the central bank does not recognize this kind of digital currency,
can be used as a virtual commodity at most,
there is a great deal of transaction risk.
2. Salinometer - to monitor the concentration of salt in water
3. Temperature control equipment - control water temperature, mainly refers to heating equipment
4. Oxygen pump - to proce oxygen for fish tanks
5. Circulating water equipment: the water circulates up, down, left and right, and is naturally oxygenated in the flow
6. Refrigeration equipment: rece the water temperature to make it less active and not easy to die
7. Filter screen is used to filter the impurities in the pool water and keep the water clean< Second, suitable conditions for shrimps:
water temperature is 18-19 ℃, salinity is 16-18%. Shrimps require clean water quality, so water must be recycled or changed at least once a day< Two points should be paid attention to when mixing seawater:
first, tap water can only be used after standing for more than half a day (and the precipitation below should be removed). Chemical dechlorination can be used. The commonly used dechlorination drug is sodium thiosulfate, and its dosage is generally 10 kg tap water plus 1 g sodium thiosulfate. Second, sea water essence (quality is very important) is the special salt for feeding seafood, so it can not be replaced by ordinary salt< 4. Oxygenation:
when feeding seafood, it does not mean that the more oxygen is, the better. If too much oxygen is added, the gas emitted by the oxygen pump will kill the seafood. With more water and less shrimp, it is enough to do without oxygen or just open the circulation< 5. Adjust the pH of water:
the pH of water is closely related to the survival of all kinds of seafood. Sodium dihydrogen phosphate and sodium bicarbonate are commonly used to regulate the pH of water quality. Before use, the two drugs should be dissolved in pure water and mixed into a solution of 1:100. Sodium phosphate can increase the acidity of water; Sodium bicarbonate can increase the alkalinity of water. When using, the prepared solution can be added to the water drop by drop according to the needs, fully stirred, and continuously tested with pH paper until the pH value of the water reaches the requirements, and the change of the pH value of the water should be controlled within 5% ± 1< (6) feeding:
generally, fish can be fed, but do not overdo it. Short term feeding can be avoided.
