About the properties of bitcoin
{rrrrrrr}
bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct

1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address

The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
"Gold and silver are not money naturally, but money is gold and silver naturally." this is a sentence Marx said about money
How to understand? In fact, it is very simple that money is the inevitable proct of the development of human life. In the earliest stage, gold and silver were only used as a kind of metal or a kind of ordinary commodity to exchange things. However, with the development of society, people find that gold and silver are easy to separate, easy to preserve, easy to carry and other advantages, so the suitability of gold and silver as currency is reflected, and naturally evolved into currencyWhat about bitcoin

The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
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 money circulationbitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold diggers by repeatedly solving riddles to provide the required numbers for bitcoin network. If the user's computer successfully creates a set of numbers

In terms of currency attribute, although bitcoin is a kind of virtual currency with no issuer, it is recognized as worthless currency in reality. Nowadays, many countries restrict its circulation, so many people do not understand it. But it does have a monetary attribute, not only that, it also has an asset attribute
the reason why many countries do not recognize bitcoin as a currency in circulation is that it has too much room for imagination and is not easy to control at the national level. Although it is more convenient, it is more abstract and naturally "shut out" by many countries. However, some countries, such as Japan, recognize bitcoin and digital currency as digital equivalent, and there are many payment application examples in Japan although it is difficult to reach a consensus on a global scale, Japan's behavior also shows that bitcoin has monetary attributes to a certain extent
(1) as an online virtual currency launched by computer enthusiasts five years ago, the latter half of 2013 became the "moment of hope" of bitcoin. In September 2013, the U.S. dollar exchange rate per bitcoin increased more than five times, from less than 5 cents in 2010 to more than $1200. Some people believe that virtual currencies such as bitcoin will play an important role in commercial payment systems. In fact, bitcoin is more like a special investment than a currency
(2) economists define three attributes of money: transaction medium, pricing means and value storage. Bitcoin increasingly meets the first attribute of money. Because more and more businesses, especially in the network market, are willing to accept payment with bitcoin. However, bitcoin cannot be stored in a bank and must be controlled through a "digital wallet" like system vulnerable to hackers. At present, there is no insurance for bitcoin ownership; No lender uses bitcoin as the unit of valuation in standard consumer finance, auto loans and mortgage; Without credit and debit cards valued in bitcoin, it can't be as short as derivatives. The absence of the latter two attributes of bitcoin seems to be the best explanation for the astronomical increase in the value of bitcoin in September 2013. Because it is difficult for currency investors to bet on the appreciation of bitcoin, optimists can only wait and see when they trade on the ever rising price
(3) it can be seen that bitcoin does not make itself a unit of measurement or embody the function of value storage. Because bitcoin fluctuates excessively and fails to correlate with the changes of other currencies, huge risk costs are imposed on bitcoin owners. Since 2013, the volatility of bitcoin exchange rate has been as high as 133%, which is much higher than that of other currencies. Gold is 22%, and most of the transferable bonds are 20% - 30%. Even the volatility of high-risk stocks rarely reaches 100%. This shows that even if bitcoin is held for a short time, the risk is also great, which is inconsistent with the storage property of currency, and weakens the function of a currency as a unit of measurement.
