Sichuan Ganzi power company bitcoin
bitcoin is one of the most popular virtual currencies, which is very popular on the Internet
recently, according to the bitcoin power consumption index released by Cambridge researchers, if bitcoin is regarded as a country, it will rank among the top 30 countries with the largest power consumption in the world. The annual power consumption of bitcoin mining is about 121.36 terawatt hours (TWH, 1 terawatt hour is 1 billion kwh){ RRRRR}
recently, Bill Gates made it clear that he is not a fan of bitcoin
Bill Gates said: & lt; Bitcoin consumes more power per transaction than any other way known to mankind, so it's definitely a very important climate issue. But if it uses green power, it may not be a problem in the end
I don't think these topics are deeply relevant, although you may label me as a bitcoin skeptic
in other words, instead of investing in bitcoin, I used the money to buy malaria vaccines. I invest in companies that make real procts. But if other people invest in bitcoin and make money, I'll congratulate them& rdquo;
Although many countries do not recognize the value and status of bitcoin, bitcoin is still popular in recent years, and its existence is controversial. Some people say that it has no practical significance, just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people say & lt; No one can be sure whether bitcoin is a black horse or not
in fact, bitcoin is calculated and proced through computer networking, also known as mining. At the beginning, there was a personal computer to dig, but the efficiency was relatively low, and the cost of graphics card was low. Then there was a special bitcoin mining machine, ranging from several hundred to two or three hundred thousand yuan
when we talk about bitcoin, we naturally need blockchain because of the blockchain, bitcoin can become bitcoin. It is a secure general ledger for all payments and transactions. It can be said that everyone can contribute to the update. We need to solve a very complex mathematical problem by brute force& mdash; Hash algorithm to complete a block
many people want to know the value of a bitcoin. In fact, the price of bitcoin is changing all the time. We need to check the figures of that day. At present, the price of a bitcoin is less than 30000
meinian health examination is reliable meinian grand health provides health examination, health management, health consultation and other services, and has outstanding influence in the medical and grand health sector. It has won "China's best corporate citizen, best social feedback Award", "2018 corporate social responsibility Contribution Award" and other honors
There are three differences between meinian physical examination and hospital physical examination:1. Medical examination population is different
1. Hospital: a place where patients gather. It is mainly responsible for the examination and diagnosis and treatment of patients and people suspected of having diseases. When they go to the hospital for physical examination, it is difficult to share the examination instruments and equipment with patients, It is inevitable that there will be a potential threat of cross infection e to disease aggregation
2. Meinian: as a health examination institution, the physical examination crowd is mainly healthy / sub-health, compared with the hospital, the health examination equipment is almost not shared with the patients, and the iatrogenic infection is eliminated
Second, the environment and atmosphere are different.1. Hospitals are built for patients and patients. They are divided according to outpatient service, department and function. During physical examination, they have to go upstairs and downstairs, or even run from one building to another. Nurses are very busy and have no time to guide them. It is too time-consuming for a physical examination
2. Meinian: it is built for the convenience of physical examination customers. It scientifically divides the physical examination areas, implements the separate examination of men and women, implements the efficient one-stop service process, and the design of humanized corridor ensures the smooth passage, and each department and passage has the guidance and diversion of inspection nurses, which greatly saves time and facilitates the physical examination of customers
3. Different service experience
1. Hospital: when you go to the hospital for physical examination, you smell the smell of disinfectant and look at the patients and family members who come and go. Even if you don't get sick, you will feel depressed for a few days when you see the injured people
2. Meinian: it's not because of illness, but to prevent it, nip it in the bud and save the cost of treatment
without comparison, there is no harm. It costs 2000 + to go to the hospital just to have a gastros. However, meinian health has launched a variety of packages with high cost performance, which are definitely the first choice for elderly uncles and aunts
According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts
extended data
unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
the state does not allow the issue of bitcoin,
so companies selling bitcoin are illegal fund-raising.
If a company only accepts bitcoin payment, it must want to hide its capital transaction records. Then it is definitely not a normal business
engineers steal millions of bitcoin from the company or face severe punishment
illegally obtaining data
the suspect is facing severe punishment
prosecutor Ji jingling, the undertaker of the case, said that according to Article 285 of China's current criminal law, it is serious to obtain the data stored, processed or transmitted in the computer information system in violation of national regulations, He shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention and shall also, or shall only, be fined. If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and shall also be fined
suspect Zhong Mou violates the state regulations, uses the technical means, obtains the data stored in the computer information system, and his behavior has violated the criminal law stipulation, the suspect is illegally obtains the computer information system data crime.
the prosecutor said that bitcoin and other "virtual currency" as a new Internet financial concept have been hot talked about by people. The central bank once issued risk tips on "virtual currency", emphasizing that China has not issued virtual currency, nor authorized any institutional company to issue it, let alone the promotion team. At present, the "virtual currency" in the market is non legal virtual currency
this case is the first case of bitcoin theft in Beijing. Although it is difficult to determine the value of bitcoin from a legal perspective, it will also violate the law if it exceeds its authority and illegally modifies the functions of computer information system, causing economic losses such as maintenance
