China's bitcoin mining

1. bitcoin mining software refers to the bitcoin mining client, this one is universal, there is no domestic or foreign saying
at present, bitcoin mining needs professional mining machines. Now bitcoin mining is a very professional thing. Retail mining has been graally eliminated, and bitcoin mining is graally mastered by several major mining machine manufacturers and owners
as long as the digital currency allows mining, it is OK to mine anywhere. As long as the network can be connected, mining generally uses ordinary computer or graphics card or professional ASIC mining machine
some digital currencies do not need to be mined, but are pre mined in advance, such as Ruitai, but Ruitai is a kind of asset mortgage certificate. Of course, most of the others need to be obtained through mining, such as Wright coin and thousand gold card mining.

2. Erdos, 560 kilometers west of Beijing, is covered with hot waves and sandstorms. The gate is a dividing line, separating the two worlds. Outside the gate is a typical landscape of China's fourth tier Urban Development Zone, while inside the gate is a science fiction scene like the matrix. Eight large factories with blue roofs are juxtaposed. Tens of thousands of "mining machines" are flashing red and green light and roaring in the factory, making digital currency bitcoin for this "mine" day and night. This once the world's largest mine holds about 4% of the computing power (proction capacity) in the bitcoin world. During the peak period, it can dig out more than 100000 bitcoins a year, which is worth more than 3 billion RMB at the price of 30000 RMB in August 2017.
bitcoin was invented by "Zhongben cong" in 2009, Using the computing power of the chip, the boring and repetitive process of constantly "hash collision" in the blocks generated by the bitcoin system to win the bookkeeping right and thus obtain the system reward of bitcoin is vividly called "mining" in the bitcoin instry, and the professional staff engaged in this work are called "in the first few years of bitcoin operation, An ordinary laptop can play the role of "mining". However, the entry of Chinese miners has completely broken the balance of this situation. Relying on professional mining machines designed and made in China, they staged one after another bitcoin world computing power arms race, raising the threshold of "mining" tens of thousands of times

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million

4. Now it's not very profitable. In 12 years, the price of bitcoin was about 1000 +. With personal PC, we could dig more than one coin a week. The current currency price is about 20000 yuan
Development:
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. West Virginia Democratic Senator Joe; On February 26, 2014, Joe Manchin issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China.

On February 25, 1968, Alex Mason, a special agent of the US Central Intelligence Agency's sad / SOG team, was tied to a chair in an interrogation room. The two men who interrogated him had been trying to get some information from him about the specific location of a digital radio station. Most of the levels in the game are made up of Mason's memories

On April 17, 1961, Mason, together with his teammates, CIA agents woods and Bauman, formed a team code 40 and participated in the US military action in the bay of pigs incident. Their mission was to assassinate Fidel Castro, the Cuban leader. Mason successfully entered Castro's official residence and shot the target himself. After that, although the three men successfully boarded the fleeing plane, the plane couldn't take off because the runway of the airport was blocked by enemy vehicles. Mason resolutely jumped off the plane and used the anti-aircraft artillery beside the runway to destroy the obstacles. The plane took off smoothly and escaped, but Mason was captured by the Cuban army

after waking up, Mason found himself by the sea, next to a large freighter with the words "water Fairy". It turned out that he was handed over to the real Castro by the Cuban army. Castro gave Mason as a "gift" to his ally, general Nikita Dragovic, commander of the Soviet army, and asked Dragovic to torture Mason

During his stay in the reform through labor camp in volkuta, the Soviet Union, Mason met Victor rezenov, a veteran of the Soviet Red Army, and became a difficult friend with him. Rezenov told Mason that he was interrogated by dragovich and his deputy, Colonel Lev krafchenko, and Frederick Steiner, a former Nazi German scientist who surrendered to the Soviet Union. All three of them had a deep connection with rezenov: in the winter of October 29, 1945, the Soviet commandos of rezenov, dragovich, krafchenko and Dmitri Petrenko were ordered to search for Steiner in the Arctic circle

after the three were arrested, they were detained for interrogation in Laos. Dragovich sent a team of Soviet special forces to assist the Vietcong guerrillas to guard the three men in the water prison. A Soviet Special Forces officer made them play Russian Roulette for fun out of boredom. Bowman was killed for dissatisfaction and eloquence, and then Mason and woods cooperated with each other, Took the opportunity to kill several guards, escaped, and snatched the Soviet helicopter parked at the gate of the camp. The two men drove a snatched helicopter to destroy an enemy camp and its oil pipeline

Then they went to another base, rescued a group of captured US troops and met rezenov again. He learned that krafchenko was in the base. When Mason was attacked by krafchenko, woods stabbed krafchenko with a dagger and rushed out of the glass window with the latter trying to detonate the portable explosive

At the same time, Mason's colleagues Hudson and Weaver found Dr. Clark in the Kowloon Walled City of Hong Kong and began to torture him. Clark gave away Steiner and a secret experimental base hidden in the yamantu mountains, while Soviet special forces raided when Clark gave out more important information. Although Clark released the pre arranged poison gas, causing heavy damage to the Soviet army, and led two agents to escape to their private arsenals to fight back with weapons, Clark said a series of numbers on the way, but he was killed by Soviet snipers when he was about to say the meaning of the series of numbers. Hudson and Weaver successfully withdrew after the arrival of reinforcements

at this time, Steiner cracked the radio frequency of Hudson and others, contacted and told Hudson that dragovich was cleaning up all the facilities and personnel related to Nova 6, and he would also suffer, At the same time, let them come to their base, wozrogziniye island in the Aral Sea, to try to stop the broadcasting of digital code: this code will allow dragovich to assign a large number of Soviet agents lurking in American cities to receive the instruction code to release nova-6 poison gas in the city. Only Steiner knows how to stop broadcasting. After that, Weaver photographed the layout point, and everyone got out of the base

since her escape from prison, Mason has been seeing the images of "fighting together" with rezenov because of the illusion of split personality caused by the extremely painful brainwashing process. In fact, rezenov was bent on revenge, so he manipulated Mason's brainwashing program. Before he escaped from prison, he changed the instruction given to Mason to assassinate Kennedy to kill Dragovic, krafchenko and Steiner. During the interrogation, the strange number that people often hear reading is the number broadcasted by dragovich. But the crisis is imminent, because Steiner is dead, no one knows the exact location of dragovich station

Hudson asked Mason to listen to the last recording of digital radio, which made Mason think of a Soviet ship he had seen in Cuba before: "water Fairy" after experiencing the painful choice between imagination and reality, and confirmed that it was where the digital radio was. At dawn, a group of people with a helicopter in the waters near Cuba found the ship, and launched an attack on it, dragovich arranged a lot of defense, but was still intruded by the U.S. military

after the successful penetration, Hudson and Mason found a hidden underwater radio station at the bottom of the ship when they searched the bottom of the ship. In fact, it was also a supply station for the Soviet submarine formation that invaded the United States after successfully releasing the poisonous gas. After confirming that the water fairy was a digital radio station, Hudson called the U.S. Navy to strike the ship within 15 minutes, but Mason insisted on continuing to search and kill dragovich himself. Then they dived into the water and found an underwater base built by dragovich. Finally, they found and killed dragovich at the bottom of the underwater base and returned to the sea safely

After successfully swimming out of the water, Weaver announced the victory, but Mason was still not sure. Finally, Mason appeared in Kennedy's film. In fact, the strangest thing was that when dragovich drowned, Mason questioned dragovich about his attempt to implant instructions in his brain. Mason accused dragovich of "trying" to brainwash him to assassinate his own president. Finally, dragovich used a rhetorical question to say "tried?"

In addition, the women in the last scene are still broadcasting the numbers and Mason appears in the photo of Kennedy's assassination. In fact, Kennedy's assassination occurred at 12:30 p.m. on Friday, November 22, 1963, just after Mason returned to the United States. Because there is a five-year gap in the plot, and no one knows what happened in the five years, it can be seen that it was Mason who assassinated Kennedy five years ago. At this time, Mason's brain is quite confused, and he may not realize that he has killed Kennedy. The story ends

extended materials:

role introction -

1. Alex Mason was born and raised in Alaska. Because Mason's hometown Alaska is close to the Soviet Union, Mason felt the threat of the cold war earlier than most Americans. This is the reason why he had a strong anti communist ideal and finally joined the USMC. When he was young, the candidate often went hunting (elk and grizzly bear) with his father in the Alaskan wilderness

so this candidate can use combat skills skillfully in cold environment and is an excellent sniper. The candidate was recruited to sad / SOG at the age of 25, ending his exemplary service in the Marine Corps. After becoming a member of the organization, Mason made a lot of contributions and got along with many colleagues in the organization, especially Frank woods

As a World War II veteran who has experienced the baptism of blood and tears, rezenov believes that he can return to his motherland like a hero. However, fate was changed forever by a post-war mission, operation Olympus

Peter Lenko, an old comrade in arms, was killed by dragovich with poison gas ring the operation and vowed to kill dragovich and avenge his old comrade in arms. After discovering that Mason was brainwashed, he took the opportunity to instill the concept of "dragovich, Kravchenko and Steiner must die" into Mason's brain, and Mason did it one by one

Jason Hudson

regardless of his age, rezenov is a machine that completes tasks and can make anything that hinders his progress feel pain. The intermittent outburst of violent tendencies clearly reflects this

after graating from Georgetown University, Jason Hudson, with a al degree in psychology and political science, was recommended by his academic tutor and former OSS field agent Marshall Bryant. Hudson can always give full play to the intelligence of that day when carrying out tasks. He is an excellent military division and task coordinator. Therefore, it is also reused by the CIA. Given leadership and crisis management capabilities, Hudson will continue to be reused

although Hudson's many missions keep him away from the front line of the battlefield, Hudson is still a qualified soldier, especially when performing tasks requiring skill and strategy

6. I am very glad to answer your question. Guess the stock market index app. I use two now, one is a flush mobile phone app client, the other is a stock in Alipay's member's score, guess the big market ups and downs, that bonus points can be changed for flowers or red packets, or his coupons and gifts, or relatively good, you can refer to the next.

7. There are too many reports about bitcoin on CCTV. At the end of 2013, the soaring price of bitcoin was closely related to the media exposure. CCTV news has reported on bitcoin many times, leading to more people to understand bitcoin. Some people have questioned that the soaring price of bitcoin at the end of 2013 was carefully planned by a domestic team or investment institution or fund. The extensive coverage of the media may be the result of their promotion. However, since the central bank issued the risk notice on bitcoin at the end of 2013, bitcoin has been on a long-term decline. CCTV's reports also changed from positive reports to negative reports.
