How to use bitcoin in China

1. 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

2. If you want to dig a mine, you should understand these first, and then decide whether to join the army of miners or not
as a miner, I used graphics card very early and then butterfly machine. At present, I use Avalon's 220 miner and just received a new 180 ant miner. To tell you the truth, mining is not as simple as you think. Here I will list some practical difficulties you need to face in mining. If you find that some of these items can't be solved and overcome for the time being, don't rush to buy a miner, because from the moment you buy, if you can't mine, Then you will face a real loss

first, list the problems to face
1, be able to accept the noise - the noise of the mining machine is very loud, which is equivalent to that you put the air conditioner outside the room
1-1, strong hands-on ability - the noise can be controlled to a certain extent by adding water cooling, but it needs to be done by yourself. The installation process of water cooling is not as simple as the online tutorial. It needs to be extremely careful. The capacitor on the logic board is easy to touch, and it must be successful at one time. Once the refrigerant is added, the machine will have problems again, It would be disastrous to dismantle the water cooling system
1-2, conditional repair of the chip capacitor - in the process of water cooling installation, the capacitor is easy to fall off, these chip capacitors are very difficult to weld
2, you can set up the network - you can't just plug in the Internet cable! Need to understand the routing, know how to change the IP of the router, mining IP is fixed, according to mining IP to do settings
2-1, you can get a fixed IP address - if you are mining in a company, you can't set up a route, so you must have the condition to get a fixed IP, and then set up your own network through this IP
3. The environment of continuous power supply and continuous network - mining is a 24-hour business. Don't take it for granted that a meeting is OK in one day. Many companies will cut off power at midnight. This must be made clear
3-1. In low temperature environment, in addition to 24-hour continuous power supply, there should also be a relatively cold environment. In actual mining, we can clearly feel the importance of temperature for mining<

let's assume two scenarios,
in the company:
if your working environment is very quiet, it is not suitable, even if water cooling is installed. If you are a senior blue collar, in the workshop, do you have the conditions to set up the network and get a fixed IP? If you can't, give up
at home:
can you stand noise? Can tolerate to a certain extent
is it possible to install water cooling? It can be installed conditionally
is it possible to set up a network? There are also conditions to set up the network
is it warm in that room? Yes, but you can open windows on the second bedroom or balcony
is it possible to pull the wire and the wiring board in the balcony? No problem
congratulations, you can buy a miner to dig it up, but if one of them doesn't work, you need to think carefully before making a decision
the above-mentioned points should not be taken as unimportant or major problems. For example, it is necessary to have the conditions to install water cooling, for example, in a lower temperature environment, for example, to have a fixed IP
when the miner starts to operate and makes a rumbling sound, if you are in the company, you have to turn it off awkwardly. If you are at home, you need to figure out how to explain to your family or girlfriend that the noise will exist for 24 hours, and hope they don't mind

if your home is warm, your miner will never be able to achieve the highest computing power it can. You must accept it calmly, don't be depressed, it's useless to find the seller. Unless you open the window to let in the cold air, you will find that you and the miner are so out of place. That's why laomaozi is very fond of mining< Make complaints about mobile phone, br / > and if you work hard to move the mine to the company, you may think that the electricity charge is in the whole province. You can't get the mine to connect. Then you can only move the mine to home or sell it as a second-hand machine...

these words are typed word by word by me. I hope it can help you. You must find out whether you are qualified to do this at present. As for how to dig, it's a very simple thing: buy a miner, register an account on a mining website, Download a multibit to store the bitcoin you get, and link the miner to the network for power on, Set up the network, give it the fixed IP specified on the chassis, use the computer to access the IP, make some simple settings, and then wait for the receipt
what else can I ask you

3.

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

4. The computer is not good, too few, can't dig

5. Create a new miner account * and add multiple accounts with *. *. The default password is 123456.

6. When many people question whether bitcoin is a bubble, let's see what the real miners do with it. The so-called "miners" are those who use computer programs to "dig" bitcoin. Bitcoin originally came from a large number of mathematical calculations. According to this method, the results of "mining" depend on how high your computer configuration is, so most people used to think of bitcoin as a hacker's game earlier - a nameless person who no one knows who started "mining" as long as your computer configuration and technical ability are strong enough, except "mining", Hackers steal bitcoin from other people's accounts several times. What do the real miners think? The first "miner" I met at the bitcoin conference was John Stahl, a volunteer at the conference, who works in a hospital and pays attention to the Internet and all the interesting things in his spare time“ I bought a laptop in the bitcoin store with bitcoin, "John told me. The operation method is that he used his own computer to dig a very small number of bitcoins, stored them in coinbase (a special platform that allows users to store and exchange bitcoins), and bought them in the bitcoin store (online store, where bitcoin is the main currency)“ I think most people misunderstand bitcoin. It's just a new virtual currency, which makes online transactions easier for people all over the world. " As a volunteer for the bitcoin foundation, a non-profit organization. John said the reason why he is trying to promote bitcoin is that it's a new means of payment: "first, it's a virtual currency, second, it's a means of payment, just like PayPal. It has its own value and can be converted into various currencies. "“ The advantage of it is that you don't have to worry about the exchange barriers between different currencies. For example, if you use RMB and I use US dollars, we can convert it into bitcoin to trade. " When I asked him what would affect the bitcoin exchange rate, I knew that the number was changing every day. He cited the experience of "miners" as an example: "just as the exchange rate of RMB and US dollar is related to the cash storage of the two currencies, so is bitcoin. Every four years, the circulation of bitcoin will be halved, and the total amount will be stable at a certain amount." What John means is that the total amount of bitcoin is so much. The more one person or some people take away, the more cost the rest of the people will have to get bitcoin, and the exchange rate of bitcoin will change. During this period, the growth rate of bitcoin exchange rates was somewhat out of line, causing many people to think that this is a reality of bubbles. John and another miner Olaf said, "this is because more and more people are involved. In essence, bitcoin comes from mathematical calculation, and its calculation becomes more and more difficult." digging "becomes more and more difficult. The transaction price will naturally increase. " Olaf Carlson wee works in coinbase. More exaggerated than John Stahl, Olaf told me that he bought almost everything with bitcoin. "Now bitcoin supports shopping cards of many websites. You can buy an Amazon shopping card with bitcoin, and then go up and consume it. That's what I do." Olaf said. They introced me to a project that sounds even more touching - a participant (unfortunately, I never found him in the conference room) "he has done three start-ups, sold them to big companies, and now he is helping some homeless people," John said. "As far as I know, he has built a website to accept donations from people all over the world, The currency is bitcoin, and then he uses it to buy things for the homeless. Of course, sometimes he needs to change them into dollars in cash. " It sounds like an ecosystem is needed, including the exchange of different currencies with bitcoin - Trading - and cooperation with other terminal platforms.
