1. Different people have different opinions. I can only tell you that bitcoin is completely legal in China. At the end of 2013, the central bank and other five ministries and commissions have clearly defined bitcoin as a special Internet commodity, and people can buy and sell it freely at their own risk
you should never expect to get rich through bitcoin or any emerging technology. It's always important to be alert to anything that sounds incredibly good or goes against the basic laws of the economy
bitcoin is a growing field of innovation, where there are business opportunities as well as risks. Even though bitcoin has been developing at a high speed so far, there is no guarantee that it will continue to grow. Any investment of time and resources related to bitcoin requires entrepreneurship. There are many ways to make money with bitcoin, such as mining, speculation or new business. All of these methods are highly competitive and have no profit guarantee. Everyone should make their own appropriate assessment of the costs and risks involved in any such project.

2. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design 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 concept of 21 million
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 is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million
extended materials:
generation principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
4. It's not said that CPU can't dig. In the beginning, CPU was used to dig. However, with the in-depth study of mining algorithms, we found that the original mining was repeating the same work. As a general-purpose computing unit, CPU designed many moles such as branch prediction unit, register unit and so on, which did not help to improve the computing power at all
in addition, CPU is not good at parallel computing at all. It can perform more than ten tasks at most at one time. This is far from the fact that the graphics card has thousands of stream processors. The graphics card is too high, so we slowly develop the corresponding mining algorithm for the graphics card
taking BTC as an example, its basic algorithm principle is to take all transactions within 10 minutes as an input and add a random number. When all transactions within 10 minutes are added with your random number, a hash of sha256 is calculated. It's almost full of integer operations. It's just like a special design for a graphics card. The graphics card is very suitable for this kind of brainless algorithm. The more the number of stream processors, the better
as far as hash computing is concerned, it is almost all independent and concurrent integer computing, and GPU is designed and proced for this. Compared with the pitiful 2-8 threads of CPU and the astonishing length of control judgment and scheling branches, GPU can easily perform integer calculation concurrency of hundreds of threads (brainless brute force cracking without any judgment is the strength of a card)
OpenCL can make use of a large number of unified shaders on GPU chip, which can be used as resources for integer calculation. The resource of stream processor of a card is several times that of N card (the same level card)
but later, we found that the graphics card is still too weak, and the computing power can be greatly improved by directly using the ALU unit of large-scale ASIC stack. The computing power of the palm sized computing board is dozens of times that of the graphics card, so now bitcoin can't dig without a special ASIC miner
although a large number of interdependent and random memory access instructions are introced into the script algorithm used in the later LTC, when the footprint is large enough, a large number of cache failures will occur at the L2 level or even TLB level of GPU, resulting in more DRAM accesses, so as to weaken the advantage of ASIC / FPGA in integer operation performance compared with GPU, However, it is still targeted to develop mining machines. At present, only specialized mining machines can dig
however, the second generation of virtual currency (such as Eth and Zec) has absorbed the experience of the predecessors' blasted algorithms, and made more special optimization on the mining algorithm to prevent the occurrence of brainless operations. It has high requirements for video memory, so it can effectively resist the invasion of mining machines
because eth can only rely on graphics cards for mining, the rising price and shortage of graphics cards started in the second half of 2017. Many mine owners sold thousands of graphics cards to set up mining machines to mine these virtual currencies
over time, we all think that CPU can't mine, but in fact, the efficiency and benefit are too low.

6. Progress of Wu Ying case:
February 13, 2007: Wu Ying was detained by criminal law
Wu Ying, Zhejiang's "hundreds of millions of rich sisters in Dongyang", who had attracted attention at home and abroad for creating the myth of "overnight wealth", was recently detained by the Public Security Bureau of Dongyang City, Zhejiang Province. At present, Dongyang municipal government has started to check the assets and capital of Wu Ying's "Bense group". More than 700 employees of the group have been paid in advance by the municipal government, and the relevant disposal work is proceeding in an orderly manner
March 16, 2007: Wu Ying was approved for arrest
with the approval of Dongyang people's Procuratorate, Wu Ying, 26, chairman of Bense group, was arrested by Dongyang Public Security Bureau on March 16, Zhejiang Province after 37 days of criminal detention for suspected illegal absorption of public deposits< On February 25, 2008, Zhejiang court accepted the case of Wu Ying suspected of illegal fund-raising.
the people's Court of Dongyang City, Zhejiang Province, has formally accepted the prosecution against Wu Ying and Bense Holding Group Co., Ltd., which were accused of illegally absorbing more than 700 million yuan of public deposits. At the same time, Lin Weiping and other seven people were prosecuted< December 18, 2009: Wu Ying was sentenced to death for fund-raising fraud in the first instance
Jinhua intermediate people's court made a first instance judgment, sentenced the defendant Wu Ying to death for the crime of fund-raising fraud, deprived of political rights for life, and confiscated all his personal property
December 28, 2009: Wu Ying filed an appeal against the death sentence of the first instance
in the appeal petition, Wu Ying put forward five appeal reasons, believing that her behavior did not constitute the crime of fund-raising fraud, and hoped that the court of second instance could change the sentence according to law< On April 7, 2011, Wu Ying admitted the crime of illegally absorbing public deposits in the court of second instance
Zhejiang Provincial Higher People's court held a court session in Jinhua intermediate people's court to conct the second instance of Wu Ying case. In the second instance, Wu Ying's defense lawyer still defended her innocence. Wu Ying pleaded guilty in court, admitting that she had been prosecuted by Dongyang City procuratorate for the crime of illegally raising public deposits< January 18, 2012: the second instance of Zhejiang Higher People's Court upheld Wu Ying's death sentence
the higher people's Court of Zhejiang Province pronounced a sentence in the second instance of the Wu Ying case, ruled to reject the defendant Wu Ying's appeal, upheld the death sentence of the defendant Wu Ying, and submitted it to the Supreme People's court for review in accordance with the law< April 20, 2012: the Supreme People's court did not approve Wu Ying's death sentence and sent it back to Zhejiang high court for retrial
after the Supreme People's court accepted the review case of the defendant Wu Ying's capital raising fraud death sentence, it formed a collegial panel according to law, reviewed all the file materials and interrogated the defendant, and now the review has been completed. On April 20, the Supreme People's court ruled in accordance with the law not to approve Wu Ying's death penalty and sent the case back to the higher people's Court of Zhejiang Province for retrial< May 21, 2012: Wu Ying's death sentence was changed to a reprieve in the retrial of the case of fund-raising fraud
after the retrial, the Zhejiang Provincial Higher People's court made the final judgment on Wu Ying's case, sentenced the defendant Wu Ying to death for the crime of fund-raising fraud, suspended for two years, deprived of political rights for life, and confiscated all his personal property
on June 5, 2014, the Dongyang municipal government took the lead in setting up a "Wu Ying case asset disposal group" with personnel from the court, public security, land, housing management, state owned assets, instry and commerce as members of the disposal group and vice mayor Chen Jun as leader. At the same time, five creditors, including Lin Weiping, were invited to set up a Wu Ying case asset disposal supervision group to supervise the whole process of asset disposal
on July 23, 2014, Lin Wencai, Wu Ying's entrusted agent, applied to Dongyang municipal government for Chen Jun's withdrawal on the ground that Chen Jun had bribed Wu Ying for more than 100000 yuan before the accident
on September 4, 2014, Dongyang Procuratorate of Zhejiang Province made a decision not to approve the arrest of Wu Yongzheng and Lin Wencai for the crime of false accusation and frame up. The criminal compulsory measure of the two persons was changed to l pending trial< Latest progress:
on July 11, 2014, the commutation case of Wu Ying, Zhejiang's "hundred million rich sister", was tried in Zhejiang women's prison. The court ruled that Wu Ying's sentence was commuted from death sentence suspension to life imprisonment< On May 21, 2012, Wu Ying, the former legal representative of Zhejiang Bense Holding Group Co., Ltd., was sentenced to death by Zhejiang Provincial Higher People's Court (hereinafter referred to as Zhejiang Provincial High Court) with a two-year reprieve for the crime of fund-raising fraud< In order to determine whether Wu Ying meets the conditions of death sentence suspension and commutation stipulated in the eighth amendment to the criminal law, the court decided to hold a court session to hear her commutation case. According to the announcement (2014) zxzz No. 484 of Zhejiang Provincial High Court published by zhefa.com, the court session was held at 9:30 a.m. on July 11 in Zhejiang women's prison, and the trial method was open trial< According to the law, the death penalty is suspended. If there is no intentional crime ring the period of suspension of execution, it will be reced to life imprisonment after the expiration of the period. If there is a major meritorious performance, it will be reced to 25 years' imprisonment. If there is an intentional crime, the death penalty will be executed by the Supreme Court
according to the final judgment, the value of Wu Ying's property seized is 170 million yuan. However, Wu Ying thinks that the appraisal conclusion is obviously on the low side and many assets are missing
on February 20, 2013, Wu Ying's family submitted a criminal complaint to the Supreme People's court, demanding that the (2012) zhe Xing Er Chong Zi No. 1 criminal judgment made by the Zhejiang Provincial High People's court be annulled according to law, and that Wu Ying's assets can fully pay off her debts
according to the relevant provisions of the criminal procere law, if the Zhejiang Provincial High Court accepts the above appeal and files a case, it should make a decision within 3-6 months. However, Zhu Jianwei said that the Zhejiang Provincial High Court has not yet made an acceptance reply to the complaint, but has not told it that it will not accept it, which is still pending, making it impossible for them to take the next action. There are still several administrative and civil proceedings in the Wu Ying case, but there is no progress at present
on March 26, 2015, Wu Ying's lawyers Zhu Jianwei and LV Haibo went to Dongyang, Zhejiang province again. After discussing with Wu Ying's father Wu Yongzheng, they decided to submit a supplementary petition to Zhejiang Provincial High Court and other departments by express mail, which may usher in a new dawn for Wu Ying's case
at the same time, in early March, the State Affairs Office of the CPC Central Committee issued the opinions on further standardizing the disposal of property involved in criminal proceedings, demanding to solve such prominent problems as unfair justice, corruption and perversion of the law in the process of disposal of property involved in criminal proceedings. Wu Ying's lawyers pointed out that there are many irregularities and even violations in the disposal of the assets involved in the case. They will urge the relevant parties to implement the spirit of the above documents.
