Payment with virtual bitcoin
According to the official announcement, digital assets and RMB recharge functions will be closed at 12 noon on September 27, and all trading functions will be closed at 12 noon on September 30. So far, bitcoin trading was officially sentenced to death
some people applaud the state's move to control bitcoin transactions, believing that this money laundering tool should have been closed long ago the invention of bitcoin in the United States disturbs the Chinese market. We should learn from Russia's ban on bitcoin. Although bitcoin makes money, it is not good for the development of the country because it is divorced from the real economy. Many young people are addicted to bitcoin and lose both money and people
however, at present, the state only restricts it, but it has not been completely banned. Big exchanges can not provide bitcoin exchange, so many of them go underground, making it more difficult to control
for young people, the state has banned trading, so it is too risky to re-enter the bitcoin market, so they should be cautious to intervene, and regret if they break the law
there is no exchange rate for bitcoin. Because bitcoin is an electronic currency and is universally used, its exchange rate is the same as that of other legal currencies
bitcoin mining and node software is based on P2P network, digital signature and cryptographic evidence to initiate and verify transactions. Nodes broadcast transactions to the network. After these broadcast transactions are verified by miners, miners express their confirmation with their own work proof results. The confirmed transactions will be packaged into data blocks, and the data blocks will be strung together to form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block, which will be integrated with the previous data block. The miner node will attach a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node keeps trying again and again until it finds the random adjustment number so that the generated hash value is lower than a specific target
because hash operation is irreversible, it is very difficult to find the required random adjustment number, which requires a continuous trial and error process that can predict the total number. At this time, the workload proof mechanism will play a role. When a node finds a satisfactory solution, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it meets the specification. If other nodes do meet the requirements by calculating the hash value, then the data block is valid, and other nodes will accept the data block and attach it to their own chain.
Last week, a paragraph about bitcoin became popular:
bitcoin broke through 5800 US dollars (about 38280 yuan) . When it was issued in 2009, 1 US dollar was equivalent to 1300 bitcoins. What is investment? It has increased by 7.54 million times in 8 years. At that time, you spent 38000 yuan to buy some bitcoin. Now you are the richest man in China, surpassing Xu Jiayin, who has 290 billion yuan
but just one week later, on October 20, bitcoin broke through the $6000 mark. Although it fell later, it reached more than $6000 again on October 21, reaching a maximum of $6147. In terms of $6000, bitcoin prices have risen 7.8 million times in eight years
according to cryptocompare, a bitcoin data provider, e to China's strict supervision of cryptocurrency trading, the global share of bitcoin market has been greatly changed. Now, in the total trading volume of the world's bitcoin exchanges, the trading volume of RMB versus bitcoin accounts for about 1.6%

the reporter noted that in the first half of this year, after Japan's legislation recognized bitcoin as a legal payment method, bitcoin's trading volume in Japan surged, and Japanese regulatory authorities have issued certificates to 11 cryptocurrency exchanges. About 58% of bitcoin trading currently takes place in the Japanese market, and nearly a third of yen to bitcoin trading takes place on the bitflyer exchange in Tokyo. In addition, the U.S. and South Korea markets also account for a large part of global bitcoin transactions - the U.S. dollar and the Korean won account for 27% and 7% of the total bitcoin transactions, respectively< br />
If the scale of a (general equivalent) trading market has grown to tens of billions of dollars, is there any reason for it to be connected to the numerous consumption systems of human beings
is it just because there is no & lt; A government & quot; Endorsement, so there is no right to participate in all kinds of markets
it is in this sense that we advocate that those manufacturers who can provide outstanding procts to the world should join the fair monetary system of Internet money as soon as possible
although bitcoin is still prone to sharp fluctuations in price (exchange rate), with the further growth of the scale of this kind of money market, it can be expected that its exchange rate fluctuations will graally stabilize
By then, as an international currency, it will be more worthy of its name. Of course, as the basic condition for the implementation of bitcoin payment, the network channel where a person lives can not be closed and restricted; Otherwise, we will lose the chance to use this kind of currencyTesla US official website supports bitcoin payment. Will you choose this payment method? I'm sure I won't choose this method of payment, because if we do it better than others, once our economy is seized by others, it's not a good phenomenon for our life and our society. Then it doesn't do us any good. Bitcoin, a currency that has been hyped by others, is dead in sight, that is, it doesn't survive for a long time, Therefore, it's better not to rely on bitcoin to run currency exchange for life, because the risk is particularly great and the profitability is not high in the face of this kind of living currency, so it's better not to use bitcoin for trading{ RRRRR}
generally speaking, we firmly believe that our current currency is very easy to use. We should never use bitcoin. Once people's operation is lost, the lifeline of life will be seized, and then our life will be dominated by others. So, bitcoin can't be used, Because this kind of hyped currency is not good for our life, and it will make us rely on this kind of virtual currency, which is not good for our life
[answer analysis] analysis of the test questions: ③ and ④ the options are correct and in line with the meaning of the question. Bitcoin in the question has its own particularity. Compared with currency, bitcoin does not have the universality of currency and can not be called currency, which indicates that the particularity cannot be separated from universality. Bitcoin can buy virtual goods, exchange money, and even buy real goods, But these are all phenomena, and bitcoin is not issued by the state, and it does not have legal taste and mandatory currency. This is the essence of things, so it is judged that bitcoin is not a currency, so it is selected. ① (2) the point of view of the option is not consistent with the meaning of the title. The title emphasizes that bitcoin is not a real currency compared with currency. It does not emphasize the specific analysis of specific problems, nor does it involve grasping things in the development, so it is excluded
test point: this question examines the relationship between universality and particularity of contradiction, and conscious choice of consciousness
Judging from the current digital money market, bitcoin and other digital currencies are not very reliable{ RRRRR}
the most important thing is that for most countries, governments also hold a negative attitude towards the current virtual currency. Many policies of various countries restrict the corresponding bitcoin trading in China, which is also an important reason why bitcoin is difficult to develop
