Real value digital currency

2.

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 currency

this 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

3. Very bad. The instry is in a mess
blockchain is not easy to do since 18 years ago. The instry is deceptive, professional cut leek. I remember that the blockchain network reported that Li Xiaolai was cutting leeks.

7. It depends on whether there is a common understanding between your set-top box and mobile phone, such as USB connection or wired connection. Or wireless connection
as long as there is a common connection mode, it can be used
e to our busy work and the rise of mobile phones, TV sets are rarely used. But home decoration and new house, TV is an essential household appliances. When buying TV, some friends are always confused and don't know where to start. Now we will start with many aspects to introce how to choose TV
image quality is always the first demand of TV. In fact, it is not difficult to understand the image quality: it is the degree of picture restoration. So from which aspect should we judge the quality of TV? Basically, resolution, contrast, color and motion are the most basic criteria for TV image quality
resolution: on the premise of the same size and film source, the higher the resolution of the TV screen, the clearer the picture. At present, the mainstream TV market is 4K TV, or UHD TV. The standard of uhdtv is 3840 × 2160 pixels. 2020 is the first year of 8K TV commercialization, 8K 7680 × The resolution of 4320 is four times that of 4K TV. In terms of resolution, it is worth paying attention to
at this time, some people may say, do I need to buy a 4K TV, because the current digital TV signals are mainly 720p and 1080p, and I hardly watch 4K film sources
if you insist on purchasing 1080p TV, you can only choose low-end TV with the maximum size of no more than 45 inches and average picture quality, or you have insufficient budget. However, the cheapest 4K TV of mainstream brands in the market is less than 2000 yuan. For new decoration or new house decoration friends, or suggest choosing mainstream 4K TV
what size of TV is the most suitable for us to buy? Taking the mainstream 4K TV of domestic first-line brands as an example, the following chart is the reference standard of screen size and optimal viewing distance
according to the visual range, the angle between the top and bottom is 30 ° To 40 ° The calculated reference distance between them. Referring to this group of charts can ensure that the picture fills the whole field of vision and get the best immersive viewing experience. However, for most of my friends, budget is one of the biggest factors restricting the size selection. Here are some suggestions
1. 55 inch to 65 inch is the most abundant and cost-effective size with large shipping volume. If you usually only watch TV programs and don't pursue viewing experience, you can choose a 55 inch to 65 inch TV set according to the above icon
2. If you use TV to watch high-definition movies and ball games, and pay attention to watching experience, the larger the screen is, the better. The recommended size is about 75 inches, because 75 inches is the upper limit of the relatively high cost-effective size in the current market
3. When the picture quality gap is acceptable, even if it is over budget, we should give priority to larger TV, because the viewing experience of large screen is improved more obviously
contrast: the contrast of TV picture generally refers to static contrast. It is the ratio of brightness between the brightest area white and the darkest area black of the screen in the same test frame. More accurately, the brightness range is one of the biggest differences between the display and the real scene. High contrast is the basis of accurate restoration of bright and dim scenes
it should be noted that for OLED TV, contrast has no reference significance. Because OLED pixels can be turned off indivially, the brightness is zero, and the contrast theoretically approaches infinity. This shows that the maximum brightness of OLED is not as good as high-end LED TV
gamut and color depth: at present, the gamut of TV sets in the market is a subset of CIE color space, and several gamut standards have been defined in the home appliance market, such as NTSC, rec.709, DCI P3, sRGB, Adobe RGB, rec.2020, etc., among which rec.2020 is the gamut standard of UHD TV sets
wide color gamut: wide color gamut is the basis of good color performance. For HDR TV sets, gamut effect is one of the main factors affecting HDR effect. The gamut coverage rate of TV sets of the same type and different grades is quite different. According to the different gamut standards adopted by various manufacturers, under the same standard state, the gamut coverage rate of TV sets of the same type and different grades is quite different, The coverage of gamut is generally qled OLED led
color depth, also known as color digit, is the number of colors that combines lightness and chromaticity. The biggest difference between color and gamut is that the influence of gray scale is considered in color depth. At present, for TV, the gamut depends on the spectral characteristics of the backlight and the matching degree of the backlight. It has nothing to do with the panel. The color depth is a parameter of the panel. If the color depth of a screen is nbit, the corresponding gray scale is 2 ^ n, and the number of colors that can be represented is (2 ^ n) ^ 3. It is set that for every 1 bit increase, the color depth will be eight times the original. The middle and low end TV sets generally use 8brt panel (256 gray scale), while the middle and high end TV sets generally use 10bit panel (1024 gray scale). The higher the connection level, the more natural the color transition
Hello everyone, I'm the maintenance of household appliances. We will update this chapter on the selection of TV sets. In the next chapter, we will continue to update how to select TV sets.

8. Directional growth has obvious advantages for listed companies: it is possible to bring immediate performance growth effect to listed companies by injecting high-quality assets and integrating upstream and downstream enterprises; It is also possible to introce strategic investors to lay a solid foundation for the long-term development of the company. Moreover, because "the issue price is not less than 90% of the average price of the company's shares in the 20 trading days before the pricing base date", the private placement base can improve the net assets per share of listed companies. Therefore, for the shareholders of circulating shares, private placement should be good< At the same time, private placement reces the earnings per share of listed companies. Therefore, private placement is a double-edged sword for small and medium-sized investors of related companies, and the good may rise the limit; If it is not good, it may fall to the limit. The standard to judge whether it is good or bad is whether it can really increase the profitability of listed companies after the implementation of SEO, and whether it infringes the interests of small and medium shareholders in the process of SEO
therefore, to judge whether private placement is good or not, we should analyze it in combination with the purpose of private placement and the future market operation. Generally speaking, for small and medium-sized investors, it is safer to invest in companies with the following characteristics of private placement: first, the target of private placement is strategic investors, which is expected to improve the company's valuation level, and then drive the secondary market share price up; Second, the target of additional issuance is group company, which is expected to be listed as a whole and eliminate related party transactions; Third, the target of the SEO is the major shareholders, who subscribe in cash, which shows that the major shareholders have confidence in the development of the listed company; Fourth, companies with better investment projects and shorter construction period with raised funds; Fifth, the current market price has fallen below or near the SEO price, and is held by the fund.
