"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
Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
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

It's not against the law
The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract
3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward
Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed
extended information:
according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "
from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all
Bitcoin is illegal in China
since September 4, 2017, China has expressed its opposition to the virtual currency exchange. On the market, large-scale exchanges are graally fading out of the domestic market. Some of them are going to Japan and some of them are going to Nanyang. Of course, with the release of new regulations in Hong Kong in early November, we believe that in the future, the virtual currency exchange may obtain a legal license in Hong Kong to serve local institutional investors
