How many years can a mine be dug
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost
therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin
bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment

extended data
bitcoin plummeted by more than 10%:
earlier on January 11, bitcoin once fell to $37000 / piece, the lowest to $35141, and the biggest drop in the day was more than 10%. According to the data of bitcoin home.com, the amount of burst positions in the past 24 hours reached US $1.165 billion (about RMB 7.530 billion), and a total of 115138 people burst positions within 24 hours
for the sudden drop, some netizens said: "what should come will come.". Cautious investors said that such a high position, I first clearance, short about
The life of the graphics card is the same as that of the general electronic components, which is 6 to 10 years< br />
at this stage, the application projects in the blockchain field are mainly divided into two aspects: one is the new business model that is more compatible with blockchain technology, such as cross-border payment, supply chain finance, proct traceability and other scenarios; The second is the application of the reform based on the existing centralized business, that is, the use of token economic incentive mechanism
with the development of technology, the number of application projects in this field is expanding rapidly, and many people believe that 2018 will be a year when blockchain will really combine with the real economy and break out. However, blockchain technology is still in the early stage of development, facing challenges including regulatory environment, lack of talents, technology awareness and so on
from the technical level, the application of blockchain technology to the actual instry scene needs to solve the problems of transaction speed, data consensus, node maintenance and so on. At present, bitcoin network can only process seven transactions per second, and the leading super ledger technology can only reach the level of 200-300 transactions; This is a long way from a centralized system with tens of thousands of transactions per second. In addition, the lack of relevant incentive mechanism in the field makes it difficult for participating nodes to operate orderly. From the regulatory perspective, although most countries actively embrace blockchain technology, there are no relatively perfect regulatory regulations and instry standards at this stage. Inappropriate regulatory measures may hinder the innovation and development of such emerging technologies
it is affected by many factors, such as the underlying technology needs to be further matured, the lack of intelligent contract public chain platform, the lack of ecological compatibility of all kinds of token, and the unclear government supervision; At present, the implementation of blockchain application projects is relatively slow, and the project quality is uneven. To this end, analysts said that compared with the general blockchain, the focus blockchain for specific scenarios and applications may be a breakthrough in the short term.
"Unfortunately, in semiconctor manufacturing, Huawei only designs chips, not manufactures them." Three months ago, Yu Chengdong, CEO of Huawei's consumer business, said at the 2020 summit of China informatization 100 people's Congress that Huawei's Kirin high-end chips could not be manufactured after September 15 e to US sanctions
the news of chip shortage and shutdown of Volkswagen in the north and the South has brought the "chip shortage" situation into the public's view again. Although it is obviously different from Huawei's chip outage, it also exposes the serious problem of insufficient domestic independent chip research and development. There seems to be a word difference between a big automobile country and a powerful automobile country. However, from the point of view that most of all kinds of chips need to be imported, we can see that the technology gap behind this is not overnight
with the rise of the trend of electrification and intellectualization, the demand for chips, especially high-end chips, will only increase in the future domestic new energy vehicle market. If Chinese auto companies want to avoid being stuck in the neck by others, they must master the ability of chip R & D, design and proction independently. Only in this way can we really achieve "overtaking at corners"
