bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below

The inventor of

bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"

In 2009, he released the first bitcoin software and officially launched the bitcoin financial system

In 2010, he graally faded out and handed over the project to other members of the bitcoin community

Nakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is

bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin

2. It is easy to understand that the main reason is that the negative impact on China's economy and society is unforgivable. First of all, these computer geniuses have a good desire to create algorithmic digital currency, but because it has no value base, the consideration of bitcoin is dominated by underground economy from the beginning, and then it becomes a tool for speculation. Secondly, every surge of bitcoin is related to Chinese speculators, which is basically the result of domestic speculation and malicious speculation. This kind of malicious speculation not only has a serious impact on China's financial market, but also creates conditions for many illegal funds to flee. Third, bitcoin and other algorithmic currencies have never served the real economy in China, and have promoted the development of the real economy. On the contrary, let the funds serving the real economy flow into the market for speculation, which has a serious crowding out effect on the real economy. Fourth, under the above circumstances, bitcoin and other so-called "algorithmic digital currencies" will surely become increasingly tools for money laundering, drug trafficking, smuggling, illegal fund-raising and other illegal and criminal activities, and the responsible government must absolutely own this market.

3. At present, there are no listed bitcoin companies in China or even in Asia. As far as I know, the only bitcoin company listed in the world is veribank group. It is a bitcoin company in Russia, which has obtained more than 20 million US dollars of financing. In the past, it mainly researched and developed and sold mining machine chips and g its own mines. Now they have evolved into a comprehensive bitcoin company

there are no listed bitcoin companies in Hong Kong, but there are many bitcoin companies in Hong Kong. Hong Kong is more open-minded than bitcoin. In China, bitcoin is defined as a special Internet commodity by the central bank, which denies its monetary attribute, but people can buy and sell it freely at their own risk. Bitcoin home network has related to the introction of bitcoin companies, you can go to a simple understanding.

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

Zhongmou, an employee of an Internet technology company in Haidian District of Beijing, took advantage of his position to steal 100 bitcoins from the company by inserting code with the permission of the administrator to modify the application program in the company's server. In March 24th, the procuratorial organ of Beijing city was informed by the people's Procuratorate of Haidian District that the procuratorial organ approved the arrest of the suspect Zhong Mou in accordance with the law on suspicion of illegally obtaining the data of computer information system. p> According to the prosecutor, bitcoin and other "virtual currencies", as a new Internet financial concept, have attracted much attention. The central bank once issued a risk warning on "virtual currency", stressing that China has not issued any virtual currency, nor authorized any institution or company to issue it, let alone a promotion team, At present, "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

7. How can you say it's bright? Didn't I answer that? Your question is too simple. There are many kinds of mining machines. You can't answer it if you just say the red light.
