3. Bitcoin was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
in 2013, the US government recognized the legal status of bitcoin, which led to a sharp rise in the price of bitcoin. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost.

4. Excerpt: yishop e-commerce system
in the past 20 years of the development of the Internet, there has never been a king in the field of B2C, only countless white bones. Even in the booming Chinese market, Jingdong is still struggling to survive, struggling to make profits< In general, there are only two ways to go for the self selling B2C: first, try to expand the scale, but lose all of them; Second, the vertical deep ploughing, the small fortune is the safety
historically, most independent B2C shopping malls started from vertical instries, such as Dangdang selling books, Jingdong selling 3C, Fanke selling shirts, and I buying online selling food. This choice is because entrepreneurs have purchasing experience and advantages in this field, and B2C in vertical fields is easy to form brand awareness
however, there is a problem in all vertical B2C shopping malls. The variety of vertical fields is single, the scale cannot be expanded, the revenue is limited, and it is very difficult to IPO, let alone explain to investors. As a result, many B2C shopping malls began to expand the scope of procurement and engage in comprehensive shopping malls. As soon as the scope of procurement was expanded, the cost rose steadily until the cost could not be controlled. Now many B2C shopping malls are taking this road, such as Jingdong, Dangdang and so on. But as early as many years ago, Amazon had already set up a purchasing center and a storage center all over the world. Later, it found that with the expansion of scale, the cost barrier increased, and the pressure rose. Soon, Amazon gave up this mode and went to engage in advertising services, music, e-book download, etc., never touching the purchasing and storage of physical goods again
if all the goods on Taobao are purchased by themselves? You can imagine what the cost is? What are the risks? Taobao has changed B into C with a move of attracting investment, which flatly throws out the cost and risk of purchasing, warehousing and sales. At the same time, zhongc has no need for IPO, so it doesn't need to make its own shops big and listed. It only needs to work hard and make a small fortune. Later, Taobao changed the big C into B and set up Taobao Mall to earn service fees. There is an old saying that when an instry makes money, it should not be engaged in the instry, but serve the instry. Taobao's model should be based on this
now B2C is a business that can make money, and many vertical B2C websites that sell underwear, diamonds and clothes are living very well, but they all have a dream of IPO. However, e to the limited scale of vertical B2C, it is easy to make money and difficult to go on the market, so they are constantly tossing around, turning themselves into traditional supermarkets with concrete and physical objects, carrying the cost to do their own sales, Naturally, it will not be suitable for the Internet era. B2C on the Internet should do value translation, realize electronic relationship, abandon cement and independent sales, and do brand and service construction
if you say that Amazon's success is an example, I can be very responsible to tell you that there are special procts in specific historical periods. Amazon belongs to the experimental results of the Internet exploration period. Now that the times have changed, we can't do experiments in the mature environment, we can only do things suitable for the mature environment.

for the sake of wealth, businessmen, programmers and civil servants have all joined bitcoin crazily. Over the years, the price of bitcoin has gone through ups and downs. Some of them are already rich, while others end up in dismay among the earliest players of bitcoin in China, there is a legendary life of getting rich overnight, as well as a tragic story of family destruction. These stories bear witness to the development history of the coin circle
in fact, in my opinion, for bitcoin, the first batch may get up early and catch up late. Why do you say that< because over the years, people who can hold bitcoin are full of faith. Most of them came into contact with each other in the past 13 years. They were sold when the price rose to more than 7000, or got off ahead of time, or plummeted after the price rose. Now it's too late. The person who holds bitcoin for a long time is the one who forgets the private key of the wallet, which means that this part of the coin is lost and will never be taken back
7.
's bitcoin is rising crazily just because central banks are constantly letting money out of the water. Once liquidity is tight, the bubble will burst. according to media reports, good news is coming from the bitcoin market again. In the latest trading day, the price of bitcoin has exceeded US $58000, a new high in recent years. At the same time, in the trading day when bitcoin soared, 140000 bitcoin investors burst their positions, accumulating more than US $1.1 billion. The bitcoin market once again suffered a double day of ice and fire. Optimistic investors continue to increase their positions and bet that the price of bitcoin will soar. On the other hand, many investors have lost their money because of shorting bitcoin
8. Huili shoes are mostly rubber soled canvas shoes
Huili is the earliest fashion brand of rubber soled shoes in China. In the 1970s, Huili shoes were almost the only symbol of sports and leisure shoes; Compared with Jiefang shoes, its concise and distinctive design is outstanding in that era of homogenization. By the 1980s, owning a pair of kickback shoes was already quite a trendy symbol among teenagers. After the reform and opening up, a large number of sports shoes brands have entered the Chinese market. Although Huili is still well-known, it is no longer the first local brand. People's impression of Huili shoes is associated with migrant workers, because it is cheap and rable, rather than a high-end brand
maintenance and cleaning of Huili shoes:
1. Most canvas materials of Huili shoes need to be coated with a layer of paste before leaving the factory e to the proction process. In order to make the vamp more upright, it is better not to use washing powder when washing, but to use soap. When washing shoes for the first time, try to wash off this layer of slurry, and wash the soap thoroughly with water after washing, otherwise the vamp is easy to turn yellow
2. Washing shoes is suitable for cold water cleaning. Of course, some serious stains may still need to be washed with warm water. But never use overheated water, otherwise the rubber is easy to open
3. Serious stains can be cleaned with 84 disinfectant. 84 disinfectant can not only be used for sterilization in SARS, because 84 has a great corrosive property, which makes the legs of clothes color, so 84 can be used to remove sweat stains. When cleaning serious stains, you don't need to dilute 84, you can directly drop 84 original liquid on the stains, let 84 stay on the vamp for about 10 seconds, and then you can brush with a toothbrush. Finally, clean 84 thoroughly with water. If not thoroughly, 84 will corrode the upper
4. After washing shoes, wrap the vamp and rubber parts with straw paper and dry them in the shade. Remember not to be directly exposed to the sun. The rubber of shoes is easy to age and open, and the vamp is easy to turn yellow. Especially the white vamp, a yellow finish
5. Wrapping the vamp with paper towel is also OK, mainly to prevent the shoes from being directly exposed to the sun. It's best to use straw paper, the worse the better, because the poor straw paper contains a lot of fluorescent agents, so on the one hand, the vamp will turn white when wrapping the shoes.
