The big man behind the lettercoin
2. Bitcoin can be copied, and lightcoin, Ruitai coin and vitality coin are all experimental objects
3. No, the source codes of different currencies are theoretically different
4. You can create counterfeit money without limit
5. It is possible in theory, but it may not work in practice.
virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies
virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software
extended data:
real risk
as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers
fraud
the private transaction of online virtual currency has realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints. In addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players
Taking Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>
impact system
in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies
if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation
reference: network virtual currency
litecoin is short for LTC, and its English name is litecoin. Litecoin stands for lightweight. The meaning behind litecoin is lightweight currency
1. Bitcoin generates a block every 10 minutes, while lightcoin LTC generates a block every 2.5 minutes. This means that lightcoin has faster transaction confirmation efficiency. Bitcoin transfer sometimes takes 1 hour or even longer to arrive at the account, but lightcoin generally takes less than 20 minutes to confirm
2. Since the LTC speed of lightcoin is four times that of bitcoin, and the reward of each block is the same as bitcoin, the total amount of money is four times that of bitcoin, which is 84 million lightcoins, which is higher than that of bitcoin<
3. Bitcoin adopts sha256 encryption algorithm, and lightcoin adopts script encryption algorithm. Compared with bitcoin, lightcoin LTC has a slightly lower computational load, which makes it easier to mine and more suitable for graphics card
(GPU) operation. At the same time, FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are better than sha256 used for bitcoin, More expensive.
1. The market depth of a digital currency, such as bitcoin and Leyte, is very deep
2. The application scenarios of a digital currency, for example, the digital currency on the coin Ying China platform will correspond to the corresponding physical assets, which are regarded as the digital currency of assets
3. The social recognition of a digital currency, bitcoin, has been widely recognized in the world
What do you mean by value? Put aside the phenomenon to see the essence, it is not gold, is a pile of characters, at present may be the so-called value is fried money, waiting for the next dish man high price take away! I do related services for blockchain projects. When we meet powerful customers who issue coins, even we will buy some. There are too many kinds on the market. I'll teach you to simply distinguish them. After all, they can filter out a large amount of junk money
what is the main body of issuing digital currency
are the relevant legal documents complete
have you ever prepared a case
what kind of exchange is it
what is the publicity effort
How about the packing
this method can be used to judge a lot of tokens. The strength is all reflected in the issuing of coins, one day, one place. Let's not say what the market will be like in the future. Even if it's money circling and running, the one with more investment will run slowly, and even if it's done well, it won't run in the long run
bitcoin is so powerful. Behind it is how many powerful consortia have smashed such a thing through years of promotion and money burning. In the short term, almost no virtual currency can replace its position.
1、 In 2009, there were 9.8424 million hectares of natural grassland in Altay, Xinjiang, accounting for 83.4% of the total land area, of which 7.2393 million hectares were available, accounting for 14.5% of the total grassland area in Xinjiang. Seasonal grazing grassland is the main part of natural grassland. Rotation grazing of grassland according to season has always been the management mode of grassland animal husbandry in Altay region. The grassland in the whole region is basically rotated by summer pasture, spring and autumn pasture and winter pasture, and only Kanas small area is rotated by summer pasture and winter spring and autumn pasture
summer pasture: it is distributed in the cool climate of the mid alpine zone, mainly using subalpine meadow, alpine meadow and alpine grassland type grassland, and the utilization time is about 3 months
spring and autumn pasture: spring and autumn pasture is distributed in the mountains of the middle mountain zone, mainly using temperate meadow and temperate grassland in the mountains, and the utilization time in spring and autumn is about 3 months
winter pastures: most of them are distributed in the plain desert area with warm water shortage in low altitude basin, and a few are located in the leeward and sunny section of low mountain and inversion zone, and the utilization time is about 6 months
the grassland in Kanas small forest area was rotational grazing in summer and winter, spring and autumn. Winter, spring and autumn fields are distributed in the meadow belt of Zhongshan Mountain with mowing conditions. They can be used in winter, spring and autumn, and the utilization time is as long as 9 months. The area and carrying capacity of grazing grassland in different seasons in Altay area (table 6-15)
Table 6-15 area and carrying capacity of seasonal pastures in 2009 in Altay area source: data from animal husbandry department of Xinjiang Uygur Autonomous Region, 2009
the area of seasonal pastures among cities and counties in Altay area also varies greatly. The carrying capacity of spring and autumn pasture is 6.3 times that of summer pasture, and that of winter pasture is 10.6 times that of summer pasture. In summer, the grassland livestock of Jimunai county were scattered to the summer pasture of Altay City, burjin county and Habahe County, while in winter, the livestock of the above three counties were herded and overwintered in the winter pasture of Sawuer mountain in Jimunai county
In terms of animal husbandry, Altay is a large agricultural economic zone dominated by grassland animal husbandry, with 7.2393 million hectares of grassland available in four seasons, which is one of the main animal husbandry bases in Xinjiang. The livestock resources in Altay area include Kazakh native breed horse, white headed cattle, Xinjiang brown cattle, Simmental cattle, Chinese Holstein cattle, Kazakh horse, Xinjiang (Northern Xinjiang) Bactrian camel, Altay sheep, Xinjiang (Northern Xinjiang type) white cashmere goat, Xinjiang Qinggeli cashmere goat and Xinjiang West fine wool sheep. Altay fine wool sheep is the main livestock species in the livestock structure in this area, In 2008, there were 2.4984 million in stock, up 19.82% year on yearin 2005, the maximum number of livestock in Altay reached 5.2823 million, and in 2010 it was 4.3348 million, which was 1.9 and 1.6 times of 1978 respectively, showing a rapid growth trend, but also weakening the carrying capacity of the grassland in Altay (Fig. 6-2). In 2010, the output value of animal husbandry in Altay was 2.197 billion yuan
Fig. 6-2 the change of the maximum livestock raising amount in Altay from 1949 to 2010 is the development period of animal husbandry in Altay from 1949 to 1965. The maximum livestock raising amount increased from 432200 in 1949 to 3167900 in 1965. The characteristics of this period are that the maximum livestock proction continued to increase, and in 1955, it exceeded 1 million heads; In 1961, it exceeded 2 million and reached 2.257 million
From 1966 to 1986, it was the period of platform development. During this period, the maximum number of livestock raised increased and decreased, but remained between 2.27 and 2.47 million. In 1982, the highest number of livestock was 3.4732 million. During this period, the average was 2.88 million There was a rising period from 1967 to 2005. The maximum number of livestock raised increased from 2.827 million in 1967 to 5.2823 million in 2005. Although it declined slightly in 1993 and 1994, it has been on the rise since then From 2006 to now, it is a declining period. The characteristic of this period is that e to the limitation of the carrying capacity of the original grass and the adjustment of the structure of animal husbandry in the region, the maximum amount of animal husbandry has been decreasing. In 2006, the maximum number of livestock raised in Altay was 5.1971 million, which decreased to 4.3348 million in 2010. It can be predicted that the maximum livestock proction will decrease by 2020, and finally reach the average value of the platform development period from 1966 to 1986, which is about 3 million Second, the characteristics of animal husbandry in Altay areaAltay area is a pure animal husbandry area, with vast grassland area, large usable area, excellent forage quality, large proportion of medium and high-grade forage species, less poisonous grass and non herbivorous grass, and more than 95% of all kinds of forage, with high utilization rate of forage
the grassland in the whole region was in a state of diversity, in which the area of plain desert grassland was the largest, accounting for 60.65% of the total available area, and the unit proctivity was the lowest, which was 1.76 HA / sheep; The minimum area of alpine steppe is 53 hectares; The highest proctivity of Lowland Meadow and plain swamp is 0.12 HA / sheep. According to the utilization pattern, there are four types (table 6-16). The winter pasture area is 3.4552 million hectares, the spring and autumn pasture area is 2.625 million hectares, the summer pasture area is 1.058 million hectares, and the spring, winter and autumn pasture area is 165900 hectares
Table 6-16 area and stocking capacity of four seasons pasture in 2008 in Altay area
data source: Animal Husbandry Bureau of Altay area, 2009
it can be seen from table 6-16 that winter pasture and spring and autumn pasture are 3.4 times and 2.56 times of summer pasture respectively according to available area, while theoretical stocking capacity is only 77.00% and 59.00% of summer pasture. In winter and spring and autumn, the number of pastures is very small, and the carrying capacity is also small. Summer pasture is the advantage and potential of this region, but it can only be used for 80 days in a year; Although the area of winter pasture is vast, it is short of water, the grass quality is poor, and the natural conditions are bad; Due to overgrazing and overgrazing, grassland degradation in spring and autumn pasture needs to be improved
from the grazing point of view, on the one hand, the four seasons pasture is very unbalanced, the winter pasture is 77.00% of the theoretical carrying capacity of the summer pasture, the spring and autumn pasture is 59.00% of the theoretical carrying capacity of the summer pasture, and the winter spring and autumn pasture is only 4.00% of the theoretical carrying capacity of the summer pasture. On the other hand, e to the sparse and low grass layer in winter pasture, livestock can not eat in every snowy year, "strong in summer, fat in autumn, thin in winter, dying in spring" and "yield rection in case of disaster" have become insurmountable barriers for nomadic proction
To sum up, the basic characteristics of animal husbandry in Altay area are grassland grazing, animal husbandry, grazing by water and grass, raising livestock by the sky, grazing and management of proction activities with seasons, which have strong regularity and dependence on nature. The balance degree of grassland in four seasons, the quality of grassland, the amount of grass stored and the climate directly affect the development of animal husbandry (1) grassland degradation is serious and overload is excessive.
e to the change of climate conditions, the impact of human proction activities, the increase of livestock carrying capacity per unit area and the lack of scientific grazing management, the ecological balance of grassland has been seriously damaged and the contradiction between grassland and livestock is sharp (table 6-17)
In addition, according to a special report entitled "fission of Altay Grassland" in Altay daily on November 12, 2009, the theoretical carrying capacity of natural grassland is 9.54 million sheep units. At the end of 2009, the actual carrying capacity of Altay area was 16.88 million sheep units, and 7.34 million sheep units were overloaded, with an average overload rate of 75%. The available area of summer pasture is 15.24 million mu, which can carry 4.73 million sheep units. The existing livestock is 6.59 million sheep units, and the overload rate is 39.00%; The spring and autumn pasture has a usable area of 39.04 million mu and can carry 2.49 million sheep units. At present, there are 6.17 million sheep units and 3.68 million sheep units overloaded, with an overload rate of 148%; The available area of winter pasture is 51.83 million mu, which can carry 2.31 million sheep units. The existing livestock is 4.12 million sheep units, and the overload rate is 71%. 79.34 million mu grassland has been degraded to varying degrees, with the degradation rate of 73%. The degradation rates of summer pasture, spring and autumn pasture and winter pasture are 58%, 89% and 72% respectively, of which 44.3 million mu are seriously degraded, accounting for 40%
Table 6-17 situation of grassland overload and degradation in Altay in 2009
note: summer pasture and spring and autumn pasture are calculated by the highest feeding amount, and winter pasture is calculated by the number of stocks at the end of the year
data source: Bureau of animal husbandry of Altay region, concted a comprehensive grassland resource survey in 2009
2007, and the number of main 9 grassland categories did not decrease, However, the biomass, height and proportion of excellent forage decreased significantly, especially in mountain meadow, meadow steppe, mountain steppe and grassland desertification (table 6-18, table 6-19, table 6-20). The grassland area in mountainous area is about 25% of the total grassland area in the whole region, but the actual carrying capacity of grassland is as high as 57.00%
Table 6-18 comparison of biomass and height of serious degradation area in 1982 and 2007 according to the data of Animal Husbandry Department of Xinjiang Uygur Autonomous Region, 2009
Table 6-19 comparison of biomass and height of mild degradation area of grassland from 1982 to 2007
data source: data of Animal Husbandry Department of Xinjiang Uygur Autonomous Region, 2009
Table 6-20 main grassland types in 1982 and 2007. According to incomplete statistics, ring the 20 years from 1969 to 1989, the valley forests of the ulungu River and the Erqis River Basin decreased by 487000 mu, and still decreased at the rate of 10000-20000 mu per year in 2009. At the same time, in order to expand the area of cultivated land, farmers and herdsmen cut down the trees around the farmland. In addition, livestock gnaw on branches, bark and tree seedlings, resulting in the continuous decline of the natural regeneration ability of the forest and the decreasing of the forest area. Affected by the abnormal climate, the snow line rises, the glacier melts, the groundwater level drops, the secondary forest in the valley dies in large area, the area of wetland in the region declines sharply, the function of forest water conservation declines, the precipitation in the whole region decreases significantly, the grassland fire and forest fire happen year after year, and the biodiversity is seriously damaged
In Altay area, there are many natural disasters in the proction of animal husbandry. The proction of animal husbandry is still extensive and depends on the weather to raise livestock. The situation of livestock "full in summer, fat in autumn, thin in winter and starved to death in spring" has been in a vicious circle. The shortage of forage in winter and spring has resulted in the low disaster resistance ability of animal husbandry proction, especially in the case of natural disasters such as gale, snow disaster and drought, resulting in the shortage of forage storage, resulting in a passive situation of big disaster and small disaster (3) it is easy to be damaged by insects and rats, and it is very serious. The area of locust and rodent infestation is over 133300 hectares every year, accounting for more than 15% of the total grassland area. Among them, the area of locusts is more than 53300 hectares. In some areas with dense rodent holes, the holes are connected, and the ground is mined out, and the grass and shrub plants on the ground are withered In 2009, the total area of grassland with water shortage and serious water shortage was 6.0388 million hectaresin order to return to the normal level, I think it's necessary to let the wave of bitcoin pass. However, even if the wave of bitcoin can pass, lightcoin or other virtual currencies will develop again, so I don't think it's realistic to expect the price rection of graphics cards in the short term.
