The survival guide of bitcoin world

1.

There are only 21 million bitcoins

"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations

{rrrrrrr}

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most 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. 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

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

2. There are only 21 million pieces of bitcoin. It is estimated that 100 million people hold bitcoin, and no more than 2% of them hold more than one piece.

3. Mining is the most primitive "exploration method" to obtain digital currency. In essence, it is to solve a complex mathematical problem with computer. If blockchain is compared to a large account book, the block in which is a page in the account book, and all miners are bookkeepers, the process of mining is bookkeeping, and also to maintain the normal operation of the whole network

take bitcoin as an example. Every 10 minutes, all the miners work out a math problem together. Whoever works out the answer first is equivalent to digging into the block and taking it as a reward to get the corresponding bitcoin. Mining equipment is the first to use computers. With the rising price of bitcoin, more and more people participate in mining. CPU mining has graally turned into a professional graphics card. In recent years, it has become a specific mining machine. This evolution is e to the problem of computing power. As I said just now, mining means "all miners work out a mathematical problem together." the higher the computing power, the stronger the hardware computing power and the faster the speed

warm tips:
① this information does not constitute any investment suggestion, and investors should not use this information to replace their independent judgment or make decisions only based on this information
2. Investment is risky, so we should choose carefully. Before making any investment, you should make sure that you fully understand the nature of the investment and the risks involved in the proct. After a detailed understanding and careful evaluation of the proct, you can judge whether to participate in the transaction

4. As an electronic currency, bitcoin has been widely recognized in the world. Specifically, bitcoin is a network-based virtual currency, which is composed of complex computer code. Bitcoin can be used to buy goods and services, and there is no issuing agency. Anyone can use specific software mining proction, and can also trade all over the world through the network. All transactions are anonymous, leaving no identity information of traders
however, investors should pay attention to the fact that e to the lack of supervision and the intervention of a large number of speculators, the price of bitcoin is like a roller coaster, with great fluctuation and high investment risk.

5. At present, the concept of bitcoin is too advanced to be popular as the mainstream currency in the world. This is e to the political and economic factors of various countries
2. For the time being, the world's major powers will not declare bitcoin legalization within 20 years, because the rules for the issuance and generation of bitcoin are not in the hands of national willers, but rather operational rules. It's its genes
3. Many people firmly believe that bitcoin is limited. Maybe one day they will find that bitcoin is not limited. It's just that capital speculation needs a concept and a means.

6. On December 5, 2013, notice of the people's Bank of China Ministry of instry and information technology, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing bitcoin risk: bitcoin is a specific virtual commodity; Bitcoin trading is a kind of commodity trading on the Internet. Ordinary people have the freedom to participate in it at their own risk
on September 4, 2017, notice of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risk of token issuance financing: it is prohibited to engage in token issuance financing activities (ICO); The trading platform shall not engage in the exchange business between legal tender and token, or virtual currency, or buy or sell token or virtual currency as a central counter party, or provide pricing, information intermediary and other services for token or virtual currency
according to the monitoring of financial regulatory authorities, recently, some lawless elements hype "virtual currency" under the banner of blockchain. Therefore, China Internet Finance Association issued "risk tips on preventing ICO and" virtual currency "trading activities in the name of blockchain".

7. The data of bitcoin can not be deleted, and there is no so-called official. Bitcoin has no issuing agency at all. As for the difficulty of calculation, it will rise with the surge of miners. A month ago, it was more than 700 million, but now it is more than 900 million. It is impossible to predict how difficult it will be in the future, but the popularity of the media should slow down after it has passed.
