National data of bitcoin use
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
bitcoin lacks stability, so it doesn't have "inherent value", it's just a virtual proct. If we recognize its legitimacy, it will have a significant adverse impact on the banks of all countries, and even can replace the currencies of all countries. Finally, a few people will manipulate the world's monetary system, which is a very dangerous existence. It's not money. Whether it's legal or not depends entirely on whether a country recognizes it as legal or not< At present, the United States, China and South Korea all think it is not a currency. Among the big countries, bitcoin is only recognized as the "unit of account" by the German Ministry of finance, but it is only a unit of account, which does not mean that it is mainly a currency.
Bitcoin, which does not belong to any country, was originally a kind of network virtual currency, similar to Tencent's q-coin, but it has been able to buy real-life goods. A bitcoin is equivalent to 6989 yuan
There is no law in China to ban bitcoin, so it is not illegal to mine and earn bitcoin
it is not illegal to buy bitcoin in China. In 2013, five ministries and commissions jointly issued the bitcoin risk notice, which states that although bitcoin does not belong to legal tender and is not legally compulsory, people can freely participate in bitcoin trading activities when they voluntarily undertake risks
"notice" clearly defines the nature of bitcoin, and holds that bitcoin is not issued by the monetary authority, has no monetary attributes such as legal compensation and mandatory, and is not a real currency. In terms of nature, bitcoin is a specific virtual commodity, which does not have the same legal status as currency and cannot and should not be used as currency in the market
however, as a kind of commodity trading on the Internet, ordinary people have the freedom to participate in bitcoin trading at their own risk
the notice requires that at this stage, financial institutions and Payment institutions shall not price procts or services with bitcoin, buy or sell bitcoin as a central counterparties, underwrite insurance business related to bitcoin or include bitcoin in the scope of insurance liability, and provide other bitcoin related services to customers directly or indirectly, Including: providing bitcoin registration, trading, clearing, settlement and other services for customers; Accept bitcoin or use bitcoin as a payment and settlement tool; Carry out bitcoin and RMB and foreign currency exchange services; Carry out bitcoin storage, custody, mortgage and other services; Issuing financial procts related to bitcoin; Take bitcoin as the investment target of trust, fund, etc
in order to avoid over hype of virtual commodities such as bitcoin in the name of "virtual currency" and damage the public interest and the legal tender status of RMB, the circular requires financial institutions and Payment institutions to correctly use the concept of currency in their daily work, pay attention to strengthening the ecation of the public's knowledge of currency, and correctly understand the concept of currency The concept of correctly treating virtual commodity and virtual currency, rational investment, reasonable control of investment risk, and maintenance of their own property security should be included in the content of financial knowledge popularization activities, so as to guide the public to establish a correct concept of currency and investment

on December 17, 2017, bitcoin reached an all-time high of $19850.
Eth is Ethereum, an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (called "ether virtual machine") to process point-to-point contract through its special cryptocurrency, ether (also known as "ether virtual machine")
can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum
extended data
compared with most other cryptocurrency or blockchain technologies, the characteristics of Ethereum include:
1. Smart contract: the program stored in the blockchain is run by each node, and the person who needs to run the program pays the handling fee to the miners or equity holders of the node
2. TERT block: merge the short block chain which is not received by the parent chain in time e to its slow speed
Proof of rights and interests: compared with proof of workload, it can save a lot of computer resources wasted in mining and avoid network centralization caused by special application of integrated circuit Not yet implemented)4. Lightning network: it can improve the transaction speed, rece the burden of blockchain, and improve the scalability Not yet implemented)
5. The development community is stable, growing, and brave in using hard forks
