Walking BTC

1.

bitcoin is a kind of network virtual currency. 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. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours

China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin

bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it

instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan

in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction

assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours

now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

3. Ankylosing spondylitis (ankylosing
spondylitis; AS It is a kind of chronic progressive inflammatory disease which mainly invades the spine and can involve sacroiliac joint and peripheral joint in varying degrees. The disease is also known as Marie str ü Mpell's disease, von
Bechterew's disease, rheumatoid spondylitis, deformed spondylitis, rheumatoid central type, etc. are now called as. As is characterized by inflammation and ossification of the lumbar, cervical, thoracic spinal joints and ligaments as well as sacroiliac joints. The hip joint is often involved, and other peripheral joints may also have inflammation. This disease is generally negative for rheumatoid factor, so it belongs to seronegative spondylosis with Reiter syndrome, psoriasis arthritis, enteropathic arthritis, etc
ankylosing spondylitis is actually a very old disease. Evidence of ankylosing spondylitis was found in the bones of ancient Egyptians thousands of years ago. Two thousand years ago, Hippocrates, a famous Greek doctor, described a disease in which patients had pain in the sacrum, spine and cervical spine
in 1893, the disease was first described in detail by Russian btchterev. In 1897 and 1898, strumpell and Marie reported the disease in detail respectively, so they named it as berteleev's disease and Ma Shi Er's disease. In the Yellow Emperor's Canon of internal medicine (Suwen · Bi Lun Pian) more than 2000 years ago, it was recorded that "those with kidney Bi are good at distension, Jiji takes the place of heel, and Jiji takes the place of head", describing the pathogenesis and symptoms of the disease. This disease has been called rheumatoid spondylitis or central rheumatoid arthritis in China since 1950s. In recent years, with the development of medicine, the understanding of this disease has been deepened. It is found that this disease is different from rheumatoid arthritis in terms of age, sex, location, pathological characteristics and various laboratory tests, There is no rheumatoid factor in the serum of patients with ankylosing spondylitis, but the positive rate of HLA-B27 is very high, which indicates that the disease is completely different from rheumatoid arthritis. So in 1963, the international anti rheumatism alliance named the disease as ankylosing spondylitis
in 1982, the first Chinese rheumatism Symposium affirmed the international unified nomenclature of ankylosing spondylitis. The diagnostic names of rheumatoid spondylitis and central rheumatoid arthritis have been discontinued. In the latest classification of rheumatism, it has been classified as seronegative spondyloarthropathy. But at present, some domestic experts believe that this name is not very accurate, because the involved tissues and organs are not limited to the spine, hip, knee, ankle, wrist, shoulder and other limb joints can be involved, and the eyes, heart, lung, kidney and other organs are often involved, which should be a systemic disease, but this diagnostic name is still commonly used at home and abroad.

10. According to foreign media reports, a new survey by firstinsight shows that women are more and more dependent on the Internet when shopping, while men still prefer physical stores

petro of the company told CNBC“ Men like to drive to the store to touch and feel for themselves. They like to execute the transaction (in the store) and then take the items home. "

he said, "female shoppers don't necessarily feel the need to go to stores in the same way."

first insight, a technology company that helps retailers choose the best price for their procts, released its findings at a shopping conference in Las Vegas on Monday morning. In December last year, it surveyed 1000 consumers about their online and offline shopping behavior

retailers should pay attention to the gap between men's and women's shopping styles e to the gender gap

petro said that enterprises should reassess their inventory in stores at a more subdivided level. For example, as men look for more procts themselves, brands should put more men's goods in stores

however, women may only want to see some of the best-selling items on display. Because they've probably seen it online, or they're going to make decisions online in the future< I think the data show that women are more price sensitive, more likely to bargain... And more likely to trade in value than men, "petro said "Men are willing to wait longer," but they don't have to do research ahead of time< According to the first insight survey, men are more likely to shop at full price retailers (42%) and discount or non price retailers (18%). Women preferred discount retailers (38%) to full price brands (31%)

petro believes that enterprises still have a long way to go to meet the expectations of shoppers online and in stores, and this "gender gap" should be taken into account

he said: "I don't think the instry is doing a good job of distinguishing itself."“ Retailers who used to be able to set their own trends don't really understand where consumers are going now. " They are used to leading rather than responding. "

nowadays, the preferences of shoppers change faster than ever before. Most people want new procts, fast and on a consistent basis. This trend is driving the development of subscription services such as stichfix, which offer new options every month

in addition, women are driving the demand for better mobile applications. According to firstinsight, 40% of women use mobile phones regularly in stores, compared with 22% of men.
