Central bank mining machinery
Now buy 120g mining machine, bitcoin at the current price, can do back to the original, it's very good. Bitcoin (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
expansion:
1. In 2013, the U.S. government recognized the legal status of bitcoin, which led to a sharp rise in the price of bitcoin. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo 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
2. On January 11, 2017, the Shanghai headquarters of the people's Bank of China and the Shanghai financial office carried out on-site inspection of bitcoin China, focusing on whether the enterprise carried out credit, payment, exchange and other related businesses without permission or license; Implementation of anti money laundering system; Fund security risks, etc. On January 12, 2017, the business management department of the people's Bank of China also entered the trading platforms such as "fire coin net" and "currency bank" in Beijing
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. 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 money circulation. 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 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
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
extended information:

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
Recently, the news about "China quietly ordered the closure of bitcoin mines" spread like wildfire. Some media learned through insiders that the central bank held a closed door meeting to rectify some mines with non-standard electricity consumption
in fact, the rectification and treatment of Mines started last year, especially after the closing of domestic exchanges last year, the relevant regulatory authorities also discussed the issue of mine retention, but the conclusion is that the reasons for closing mines are not sufficient, and the mines have not caused more social problems, and the risk points are not clear, so no specific arrangements have been made. However, all localities have received "window guidance", that is, local enterprises can not participate in digital currency mining
in 2016, China's power generation ranked first in the world, and the total power generation accounted for 25% of the world. In this case, according to common sense, mining power in China is indeed the most abundant, especially with the decline of China's economic growth, the wasted power resources are increasing
the electricity of power stations can not be stored, but if the electricity is converted into digital currency, it can be stored. In fact, if China's surplus power generation can be converted into bitcoin for storage, it should be the most efficient mode of proction and operation. It is equivalent to procing US dollars with electricity. It is a processing export mode with the highest added value
in addition, according to the historical development, most of the power in the future may be consumed by computers. This is a judgment I made, which can be witnessed by our generation. In our daily life, the proportion of electricity consumption will be lower and lower. In the future, mankind will solve all kinds of problems by means of digitization and blockchain, and "mines" will only increase, not decrease. Especially with the development of artificial intelligence, space exploration and other fields, the demand for computing power will increase exponentially
electricity is just a kind of energy, just like a person, the biggest energy consumption is not the limbs, but the brain. The human brain is a 24-hour machine. A thinking person's brain consumes 75% of the liver's stored blood sugar every day, and the oxygen consumption accounts for 20% of the whole body's oxygen consumption. The more the brain thinks, the more glucose the neurons need
When the electric lamp was invented 200 years ago, people thought that the best use of electricity was to light the bulb. Has the final say that what electricity market will be most effective in future? p> No one can see electricity. Up to now, it is difficult for many people to understand the mystery of its existence, but electricity has changed the world. The influence of many virtual things is often greater than that of physical things. What does "digital assets" mean to China and the world? I think it is difficult for many people, including the government, to make clear at this time. What we need to reflect on is that apart from the four great inventions, such as electricity, light, telephone, computer, digital currency and so on, how many of the things that are pushing mankind forward are invented by Chinawhen a phenomenon appears, we must study the background and logic behind it. The future competition can be said to be military competition, economic development competition and financial competition, but it can also be said to be ideological and computational competition. It's easier to close mines than to stop trends
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<

Although many investors know nothing about bitcoin mining, they still can't resist the temptation of bitcoin price and plan to invest in the mining army. So if you also want to mine, I believe you will have a question in your heart: "what is a bitcoin miner? What is the principle of bitcoin mining machine? " To solve this problem, let's remember some popular science today
origin of bitcoin
to fully understand the origin of bitcoin, we have to mention the existing financial system
bitcoin mining machine specially used for mining. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world
with the orderly implementation of cashless society, banknotes will inevitably disappear in the long river of history with the passage of time. The future digital currency is believed to be similar to bitcoin, but it is by no means a limited supply. But when the human ability to proce wealth can be completely matched by the computing power of the computer, the issuing speed of e-money is directly proportional to or slightly exceeds the computing speed of the computer to create moderate inflation. In the future, while mining, it is also creating value rather than wasting electricity. In the end, the small changes in proctivity of digital currency match the difficulty of computing power, which may be the final form of human currency
2) in the notice issued by the five ministries and commissions, bitcoin is defined as "special commodity", which can be legally held at its own risk
3) at present, there are three risks in bitcoin: cross risk, price risk and "running away" risk. Due to the characteristics of anonymity, no national boundaries and no easy tracking, bitcoin is graally used as a means of exchange and payment by criminals. According to the Xinhua article, in a recent on-site inspection of major trading platforms in Beijing, the central bank found that both Huo coin.com and okcoin.com used the deposit funds formed by investors' recharge to purchase financial procts, totaling about 1 billion yuan. New things are developing too fast, so supervision must keep up with the pace, actively improve the system and regulations, and put bitcoin into the cage of supervision. In the face of serious violations of bitcoin trading platform, supervision should never be soft handed and shut down.
