Can China mine bitcoin

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.

No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

At present, bitcoin needs to be g by professional mining machines. 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

according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation

extended data:

because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners

the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin

4.

As of July 24, 2020, the state has not issued any laws to prove that bitcoin mining machine is illegal

bitcoin mining machine is one of the ways to obtain bitcoin. Bitcoin is a kind of network virtual currency proced by open source P2P software

it doesn't rely on the issuance of specific monetary institutions, and it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

extended data

the issue and transaction of bitcoin are realized by mining, and it is cast at a certain but slowing rate. Each new block is accompanied by a certain number of new bitcoin from scratch, which is used as a coinbase transaction to reward the miners who find the block

the reward for each block is not fixed. For every 210000 blocks mined, it takes about four years, and the currency issuance rate is reced by 50%. In the first four years of bitcoin's operation, each block created 50 new bitcoins. Each block creates 12.5 new bitcoins. In addition to the block award, the miner will receive a handling fee for all transactions within the block<

5. As a blockchain researcher, many new people often ask this question. In fact, if you want to own a bitcoin, there are mainly two ways. The first is to buy it directly from the corresponding digital currency exchange; The second is to mine for bitcoin
first of all, mining is the main way to obtain bitcoin, but the current threshold of mining is relatively high. If you choose to mine by yourself, first you need to understand certain technology, then download the bitcoin client and mine by yourself according to the online bitcoin mining tutorial
however, in theory, bitcoin can still be mined with computers or graphics cards. However, e to the development of mining instry in recent years, the whole network computing power of bitcoin is extremely terrible (more than supercomputers), so if you want to mine with computers or graphics cards, you can't find bitcoin, If you want to dig bitcoin, you still need to buy mining machines. Now the better mainstream mining machines in the market have to be tens of thousands. Of course, there are cheap second-hand mining machines, but these second-hand mining machines are all obsolete ones, and the electricity cost of mining is relatively high
in addition to the second way of direct purchase, the digital currency exchange is a special place for bitcoin trading. If you want to own a bitcoin, you can buy it directly with money. However, it should be noted that there are many digital currency exchanges in the market at present. Many small exchanges are specialized in cutting users and eating customer losses for a living. Therefore, when choosing an exchange, it is better to focus on the head exchange. For example, Hufu, one of the head exchanges in China, I have been using it for nearly two years, and it is very stable and safe.

6. Bitcoin is not recognized in China now, and it's very oppressed. It seems that there is a bitcoin website in China

7. Of course, it's legal. Although the state banned bitcoin trading last year, it's because some people use these investment channels to launder money. So banning bitcoin is not to say that bitcoin is not approved. And it has nothing to do with bitcoin mining, otherwise bitcoin will not go up. At present, there are thousands of mine owners in the market. It shows that this investment project is still profitable. In addition, if you have any questions in this regard, please feel free to consult me

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

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

9. Not to mention that there is no law for the time being. What will the government think of it in the future
