Bitcoin can't even afford one

4. 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 a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

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
