1. On May 22, 2010, Laszlo hanyecz, a programmer in Jacksonville, Florida, bought $25 worth of pizza with 10000 BTC. Up to now, it's about $2720 a
bitcoin. If you want to know more about bitcoin or
blockchain, you can follow Youku's "Yangyang interview"
2. 
finally, we get the following relationship between bitcoin price and number of users, which is the logical relationship. It is a kind of equation to describe the relationship between the number of species and time in biology, so the title of the paper is "bitcoin spreads like a virus"
the study also found that this relationship is not accidental, but there is a law behind it, which is Metcalfe's law
Metcalfe's law
in the 1980s, Robert Metcalfe, the inventor of Ethereum, proposed a method to evaluate the value of the Internet. He believes that the value of the network is directly proportional to the square of the network nodes (users). This is the so-called "network effect". The more users, the greater the value of the network
in a network with n users, the number of links between each user and other users is n (n-1) / 2. When n is large, n (n-1) / 2 is about n & # 178;. In this way, Metcalfe's law takes the following form: network value equals the constant c times the square of n
However, if n grows linearly with time, the network value will grow exponentially with time, and there is no boundary, which is obviously not in line with the reality. Therefore, in 2013, Metcalfe revised that n should be logistic growth, which is known as "s" growth
this rule is not only applicable to bitcoin, Peterson also studied the price change of Facebook over time, and found that the price of Facebook also applies to Metcalfe's law
3. Bitcoin traded at about $31000 to $32000, down 20% from the record high set two weeks ago, but still up about 700% from last March's low of $3850. With the resurgence of the encryption market, recently, NVIDIA also reported that it is considering re launching procts mainly for bitcoin and cryptocurrency miners. There is no doubt that more and more giants have focused on bitcoin
before 2020, bitcoin is still stable at about $5000. But a global epidemic, so that this kind of
virtual currency is suddenly given a very high value<
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
4. The value of bitcoin: 1. It can safely save property, based on block link technology, cryptography technology, decentralized, unchangeable, open source code. 2. Global circulation. Some friends who are engaged in foreign trade know that its role is huge. 3. Its total amount is limited, unlike sovereign currency. 4. There is an expectation of appreciation, and the penetration rate of the whole human being is less than 1%. 5. Big positive: Legalization of bitcoin payment in Japan
the most important thing of this virtual
digital currency is the algorithm, so if the State supports it, it will still soar~
5. One of the factors related to the price rise of bitcoin is the cost of proction, which is becoming more and more difficult with the discovery of bitcoin. However, the degree of growth is still small compared with the current price. 2. Operating costs, bitcoin exchange technology. To be honest, the risk is too great. This kind of high-tech thing is stolen just like the Internet. You don't even know who did it. The police don't have this technology. In addition, bitcoin is not protected by law in China, so you know. 3. The market share and the pricing of a new proct are decided by several groups of people with relatively mature technology and relatively early development. In the hands of retail investors, bitcoin is a small number, most of which are concentrated in several groups. They determine the exchange, price fluctuation and decisive market funds of most bitcoin, just like China's stock market, Listed companies or those listed companies, the flow of capital is the final factor that determines the market changes
6. Some people say that it can rise to 100000 US dollars or even higher. If bitcoin can act as "digital gold" in the end, its value is immeasurable! And a bitcoin is a big unit, the smallest unit is Cong, 1btc = 100000000 Cong!
7. Now our country has not allowed bitcoin trading, ha, you can consider giving up ha
I hope my answer can help you. Please accept it. Thank you.
8. I'm looking forward to 20000
9. Break through 8000 and it will rise to 15000!
