Bitcoin memorabilia
The reasons for the sharp rise of bitcoin are very complex, mainly e to the continuous admission of institutional users through the compliance channel. In short, many bitcoin holders do not really understand bitcoin itself, but just regard it as an investment proct with huge profits, but ignore its risks
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
e to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

The rapid rise of bitcoin's price comes from the fact that its use value is graally recognized by popular business services such as green ecology. For example, Jack Dorsey, the founder of Twitter and square, made a high-profile promotion and planning of BTC in Silicon Valley in the United States, which is also called the original ecological currency of the next generation Internet technology, and announced the purchase of $50 million BTC< naturally, apart from the Internet technology circle, it is also like the BTC Private Fund released by grayscale, a financial enterprise, which helps traditional financial enterprises get BTC financial planning

According to foreign media reports, although the price of bitcoin has dropped sharply this year, the cryptocurrency conference is still a major event
This week, coindesk, a well-known bitcoin news website, will hold a three-day bitcoin conference in New York City with a ticket price of about $2000. It is expected that 4000 people will attend the meeting, which is a lot more than last year's 2700 people. As a result, ticket revenue for the conference will be at least $8 millionwithin a few days of the bitcoin conference in New York, there are 20 other conferences held at the same time, and the ticket price of these conferences is also very high. Three years ago, the consensus conference was first held, and only 400 people attended. Now, the conference has become the main feature of blockchain week NYC
before and after the consensus meeting held in May last year, the price of bitcoin soared to about $2000. Of course, this is also the result of the first tokensummit summit and ethereal summit
since then, the price of bitcoin has skyrocketed, successfully attracted the interest of Wall Street, and exceeded $10000 for the first time after the consensis invest meeting held in November. In December, the price of bitcoin peaked at more than $19000. But since then, its price has fallen by more than half
strong speaker lineup
this year's speaker lineup shows that the cryptocurrency instry has taken an important step towards the mainstream direction. Jack Dorsey, co-founder of microblogging site twitter, is e to speak at the consensus conference on Wednesday. Square, his mobile payment company, also launched bitcoin trading this year. Other members of the meeting's expert group include government officials and heads of start-ups
"the consensus conference is very famous. If you give a speech at the conference, it means that you are also very famous." Said Michael oved, co-founder of airswap, the cryptocurrency exchange. He is also the organizer of the fluidity blockchain conference held last Thursday
he said that he deliberately lowered the ticket price of his fluidity conference to $150-250. Because he thinks it's a "good opportunity for us to share what we're studying.". About 700 people attended the fluidity conference, and ticket sales reached about $140000, oweed said
"ironically, the organizers charge a lot, but they never pay the speakers. These speakers are the people who are most concerned about the development of the blockchain community and are most eager to share new developments. " She tweeted on April 28
she will give speeches at ethereal summit and consensus meeting this week“ Neither of these meetings paid me for my speech. " She said. She added, "live online is a great way for the public to watch the content of the conference."
"too many meetings, it's crazy"
all kinds of meetings are very powerful and lively, but we don't know whether they finally help start-ups, especially those with imperfect management
"there are too many meetings now. It's crazy." "In the San Francisco Bay area alone, there's a weekly meeting on blockchain," oweed said. It's easy for us to be distracted by these meetings. "
however, some people are convinced that these meetings will eventually be the catalyst for the recovery of bitcoin prices
"after the previous consensus meetings, the price of bitcoin will rise. This fact strongly supports our view that the price of bitcoin has hit the bottom this year. " "During every meeting, the price of bitcoin goes up 10-70%," Tom Lee, co-founder of fundstrat global research, a market research firm, said in a research briefing on May 7
he added, "considering the significant increase in the number of participants, we believe that the price of all cryptocurrencies will increase similarly."
These two years have been eventful. People around the world novel coronavirus pneumonia. With frequent earthquakes in Japan, it is said that the Fukushima nuclear power plant may explode, and it may also cause the leakage of nuclear waste water. The leakage of nuclear waste water is only one of the risks. It is said that there is a risk of increasing the amount of nuclear radiation at the Fukushima nuclear power plant. This is Japan, Iceland. Recently, earthquakes are very frequent. It is said that there is a risk of volcanic eruption. Then the United States, the United States COVID-19 super serious, the number of confirmed COVID-19 COVID-19 has reached 30 million, the number of deaths has reached 500 thousand, in addition to COVID-19, the United States also experienced a large cold wave, the cold wave led to Texas Texas water and power cuts, businesses shut down and shut down, and many of these businesses are chip manufacturing enterprises. It's a big event for chip manufacturing enterprises to stop proction. Chip is the heart of many manufacturing instries. Without it, mobile phone, automobile and other manufacturing instries will have to stop. No, the stock price of automobile is falling these days. The lack of core is one of the important reasons
Second, summary:
therefore, this kind of method to obtain bitcoin & quot; mining & quot; It will consume a lot of chips, which is the real reason for aggravating the lack of core. And with & lt; Mining & quot; This kind of behavior will proce a lot of carbon dioxide. I think all countries should strengthen the supervision, not just for the sake of pursuing interests and ignoring the problems it brings

at the end of this year, we want to take stock of some impressive Chinese stories to say goodbye to 2017. It's a bit of a drag to take a stock of history. For things that happened a hundred years ago, there may be blessings of professional identity. For the history that just happened, smart historians generally stay away. It's not history, it's a record. Record our opinions, leaving a small group of people's memory
1. Bike sharing: fight for the right of way for civilians
no one thought that in 2017, the streets of many cities in China would be occupied by colorful bike sharing. The roads in cities are becoming wider and wider, but the roads for bicycles are becoming narrower and narrower. Many first - and second tier cities have even cancelled bicycle lanes after 2000. Just when people think that bicycles will decline and the right of way in the city will be monopolized by car owners, bicycles will come in the name of "sharing economy"
It is true that bike sharing has brought many new problems in urban management, and some enterprises are left behind by poor management. These are the inevitable development of new things in the wave of market economy. We can not expect bike sharing to provide a perfect solution At the end of November, China and South Korea respectively issued a statement saying that they had reached some "preliminary" consensus, including: South Korea agreed not to deploy "Sade" any more; South Korea agreed not to deploy "Sade" any more; Not joining the US anti missile system; We should not develop the US Japan ROK military alliance. South Korea's "three no" commitment has shown the world China's determination and ability to defend its national interests On June 18, more than 270 Indian border guards, armed and equipped with two bulldozers, crossed the Sikkim border for more than 100 meters at the dokala pass and entered China to obstruct China's road building activities. The number of Indian border guards crossing the border reached more than 400 when they reached the maximum. Together with two bulldozers and three tents, the depth of crossing the border reached more than 180 meters. India's actions have caused tension. During the 71 day illegal cross-border of Indian troops, China has repeatedly negotiated with India through diplomatic channels to clarify China's solemn position and clear requirements. At about 14:30 p.m. on August 28, the Indian side withdrew all the cross-border personnel and equipment to the Indian side of the border, which was confirmed by the Chinese field personnelChina has a long border with 14 countries and is facing a complex border situation. The two direct contests between countries in 2017 show that we are still full of challenges and crises on the road of the rise of great powers
