Huaxia digital Monetary Fund
The main concept stocks of digital currency include Hailian Jinhui, Julong, Huijin, radio and television express, digital certification, Kunlun wanwei, gaoweida, Huali chuangtong and high beam software
from the perspective of financial institutions' layout of digital currency concept stocks, according to the No.1 Institute of finance, among the relevant stocks that have disclosed the annual report of 2019, as of the end of the fourth quarter of last year, five stocks were heavily held by institutions such as insurance capital, securities companies and funds, with a total market value of 24.3 billion yuan
in terms of research on financial institutions, No.1 Institute of Finance found that six digital currency concept stocks, namely, radio and television express, digital certification, Kunlun wanwei, gaoweida, Huali chuangtong and Gaoguang software, have been intensively researched by institutions this year, with a total of 163 times of research
an equity investor of an insurance company told the No.1 Institute of finance that at present, the insurance capital still pays attention to the large cap stocks with "low wave dividend" (stocks with high dividend and low performance fluctuation), and still holds a wait-and-see attitude towards popular concept stocks such as digital currency, but does not rule out the subsequent purchase
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 determined, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by excessive 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 emergence of bitcoin poses a great challenge to the existing monetary system. Although it belongs to the generalized virtual currency, it is essentially different from the virtual currency issued by network enterprises, so it is called digital currencythis paper compares digital currency with electronic currency and virtual currency from the aspects of issuing subject, scope of application, issuing quantity, storage form, circulation mode, credit guarantee, transaction cost and transaction security
however, there are also some non developers who use the cover of digital currency to carry out pyramid selling activities, such as the Vicat fraud, treasure coin fraud, Porter coin fraud and so on exposed by bitcoin home
Domestic oil prices may rise for the first time in 2021. Accumulating the price adjustment at the end of 2020, the implementation of this price adjustment will be the first "five consecutive rises" since the implementation of the current price adjustment mechanism in 2013
assuming that the oil price doubles in 2021, the sales of new energy vehicles will definitely increase by at least 10 percentage points on the basis of what they should have. If it doubles, it is estimated that the sales of fuel vehicles will be cut by half in 2021, and the sales of new energy vehicles will be doubled
although oil prices at home and abroad showed a "rising trend", domestic automobile consumption still maintained a stable growth trend. According to the prediction of China Automobile Instry Association, the automobile sales volume will reach 26.3 million in 2021, with a year-on-year growth of about 4%. At present, affected by the Spring Festival effect, major automobile brands are actively carrying out promotion and marketing activities, and automobile consumption demand will be released in January
the rise of oil price will be directly transmitted to the power instry and other energy instries, resulting in the rise of the price of power procts. But different from the coal instry as a whole, the direct benefit is that the impact on the power instry can not be generalized. The rise of coal price leads to the rise of thermal power cost, but the cost of hydropower, wind power and nuclear power remains basically unchanged. Therefore, the rise of oil price will form a differentiation for the power instry, and the advantages of power enterprises mainly using emerging power generation methods will be highlighted
as for BLC digital money fund, which is the mainstream currency circle, it does not exist, let alone is unreliable, so it is recommended to stay away from it. It is suggested that we pay attention to bitcoin, lightcoin, DCT and other mainstream digital currencies.

Note: after the initial installation, Google Earth will automatically select the same display language as the current computer operating system, but if the language used by the system is not yet supported, it will default to English version. For example, most operating systems in mainland China use simplified Chinese Windows system, but Google Earth does not support simplified Chinese at present, So it will be displayed in English by default
1.6 select server
note: this section is only applicable to Google Earth pro (Professional Edition) and EC (Enterprise Edition) users
when you start Google Earth Enterprise Edition for the first time, a "select server" dialog box will pop up, which allows you to select an appropriate database server to use. This dialog box contains the following settings:

tip: when you add a database server, Google Earth will not disconnect the current server connection. At this time, the data you browse will come from two databases at the same time. In this way, you can synchronously obtain the satellite data from up to eight databases<
1.9 browse the earth
you can browse the earth and terrain in a variety of ways, such as:
operate with mouse
operate with navigation panel
control with keyboard
let's take a look at a related video first:
you can also view 3D terrain by tilting. Of course, at any time, you can return to the view of up north down south, vertical view
1.9.1 operation with mouse
generally speaking, the annualized interest rate (if any) of the fund will basically exceed this figure
however, high yield means high risk at the same time, and the fund also has the possibility of great loss. After all, it is restricted by the external market factors
I suggest that you take a closer look at the composition, investment target, fund manager, investment target of the fund Previous performance information
so that you can have a better judgment
