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 a decentralized and decentralized monetary system. From the government's point of view, it is not whether it should or not, but it must carry out supervision, and find out the beneficial part in its development process for traction
whether the private economy's acceptance of bitcoin is enough to form an irreversible trend depends on the game between the government and indivials in this process
if the existing monetary system brings more benefits to most nodes in the economic chain or to you, you will not choose the trading scenario of bitcoin from a personal point of view
for example, why do you use bitcoin: is it more convenient to pay? Is trading safer? Is it cheaper to buy a computer? Or for speculation
if most people who use bitcoin are speculative, it is morally reasonable for bitcoin to be regulated in the process of normal social and economic development.
The vice president of the people's Bank of China said in an interview that through this market fluctuation, we will study the regulatory rules of bitcoin. As we all know, the price of bitcoin has been rising rapidly, attracting the attention of countless investors, but it has been followed by a sharp decline of bitcoin. Because there is no way to regulate such a virtual currency, its capital flow has become a puzzle. This time, the people's Bank of China said in an interview that it would study such a virtual currency, which obviously sent a signal. So today, let's discuss the difficulties in the regulation of bitcoin{ Third, how do you view this interview
this interview not only expresses that we will carry out strict supervision over the special currency, but also expresses another attitude. That is, bitcoin, as an investment currency, has been included in the scope of compulsory regulation nationwide, even worldwide. At the same time, we also need to understand that although bitcoin has investment properties, it can not replace currency itself
In fact, there is one more detail that we need to pay attention to, that is, the price of bitcoin has been directly reced from US $60000 to US $52000, and countries have directly indicated that they will strengthen supervision. Before that, you should know that the price of bitcoin soared from more than 10000 US dollars to 60000 US dollars. It's boring. Why didn't the regulators of various countries directly intervene in such a long period of time? So today we will discuss the factors that affect the fluctuation of bitcoin{ Third, the confidence of consumers or investors
in the past few months, bitcoin's long-term success is that the manual has brought her a high degree of popularity, and at the same time, its price has gone up by leaps and bounds. But everyone is tired. After seeing some information about bitcoin for a long time, we are not very interested. The visual impact of tens of thousands of dollars has lost any freshness. In this case, everyone's investment enthusiasm for bitcoin will naturally decline, which will lead to its price decline
absolutely impossible
you can imagine this picture: payday is coming, your cold wallet has received 0.05 bitcoin, according to the bitcoin 60000 US dollars, you have earned 3000 US dollars this month, a total of 20100 RMB! You are very happy, just as you are going to have a big meal to reward yourself, bitcoin suddenly plummeted from $60000 to $50000, and it is still falling!! Your 0.05 bitcoin is still so much, but your income instantly reced to 16250, nearly 4000 yuan evaporated, not only that, but also the amount continued to decline with the naked eye!! At this time, I'm afraid no one would like to invite you to a big meal. Instead, I nervously took out my mobile phone and quickly sold bitcoin! When the transaction is completed and RMB 16000 is paid to your account, you will finally relax...
so why is bitcoin easy to store money and transfer assets? This is determined by its design principle. Professional knowledge is too complex. In short, bitcoin is a code city that can't be broken by hackers. All users involved in bitcoin trading in this city can't trace their real information through any technical means. Therefore, bitcoin has become a pure land of assets that governments can't control. In this city, your private property will always be yours, No one wants to take it away. If you forget your password, it will be miserable, because you don't want to take back your own bitcoin. It will be stored in this city forever. Therefore, the extreme security and secrecy of bitcoin make it easy for private property to completely get rid of the control of sovereign states, so it is reasonable for governments to study regulatory methods, because bitcoin is the most powerful in history, which can fight against the country's enemies economically
