Bitcoin explanation

2.

The earliest is a kind of network virtual currency. 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 U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar

< H2 > extended information:

bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address

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

many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin

3. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. 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 money 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.

4. I will analyze my personal cognition of the value of comparative currency from two perspectives:
1. A little thought on currency
at present, the currency issued by all countries in the world is basically credit currency. For example, the US dollar has been decoupled from gold since the Bretton Woods system. It is generally believed that the value of the modern dollar is supported by the national credit, or national strength and military strength of the United States
however, this is specious. Because the national strength and military strength of the United States cannot be quantified, who can tell me how much the national strength and military strength of the United States are worth? Since it is impossible to quantify, how can we ensure that the US dollar is not printed too much? In fact, there is no guarantee. On the other hand, it says "in God we trust" on the dollar, which is to tell you clearly that the dollar is actually a kind of faith. It's like trump supporters shouting, "America! USA! ", People's trust in the dollar is not purely rational, but a mixture of rationality, pride, sacredness, speciousness and habitual thinking
and this kind of trust is also fragile. In recent years, for example, the Thai baht and ruble have dropped by 40% or 50% overnight, which is also common. Even more outrageous, for example, the government of the Republic of China basically cheated on the golden yuan
bitcoin is also true. Its value comes from trust, but it is not backed by the government's credit endorsement. The letter of bitcoin is a more pure letter, because it is more invisible than the legal coin, but there is a small group of people who believe in it, such as me. This kind of letter comes from the simplicity and strength of bitcoin technology, from the ideas beyond the times contained in it, from the dissatisfaction with the existing monetary system, and from the natural yearning for progress of human beings
2. Bitcoin price and reflexivity
Buffett's value investment theory is very popular: because of people's fear or greed, the price of a thing may temporarily be higher or lower than its value, but it will eventually return to the value itself
Soros's view is that because of the fragility of human nature, a thing can never return to its value. That is to say, the correction must be over correct. When the value of a thing is absolutely undervalued, then in the process of rising, people's awareness of its rising is constantly strengthened, which often leads to crazy buying, and the final price will rise to its own value, and vice versa
in this process, the rise of price leads to people's pursuit of a thing, and people's rising expectation will continue to push up the price of this thing
Soros calls it reflexivity
for example, there is a prophet in the village. He told us that gold would go up and we should go to buy gold. Everyone flocked to buy gold. The supply of gold was in short supply, and it rose as expected. So everyone said that the prophet was right
this process has nothing to do with the basic value of gold or the actual demand for gold
if you look at it with a magnifying glass. In this process, the bullish view of gold is constantly strengthened. Because gold also rose in the process. If in the first rise callback, someone sold. When it goes higher for the second time, this person will feel that his operation is particularly stupid, so he will not easily sell when he buys again next time. Even if he sells again next time, there will always be a time when he will "learn to be smart" and no longer sell
man is also a social animal. So this expectation of rising will continue to spread and "learn" from each other, aggravating this weakness of human nature
often when a bubble burst, most people could not escape. A few rational people can run away, a few win the majority and make a lot of money. In the book mob, it is said that the IQ of a group is often lower than that of a person. In management, this is called herding. In China's stock market, this is called "retail dividend". You don't see how many people earn money every day on the platform, even wealth is free.

Bitcoin is a virtual encrypted digital currency in the form of P2P

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

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

features of bitcoin:

1. Circulation around the world: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

2. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

3. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
