May 2020 bitcoin mainland personnel movement
bitcoin was born in 2009, and it has entered China since it appeared
extended information:
bitcoin:
bitcoin can be used to cash and can be converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
generation principle:
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone
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
the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history
extended data
users can buy bitcoin, and at the same time, they can "mine" bitcoin by using computers to perform a large number of calculations according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
from 2012 to 2014, bitcoin swept the world, and graally formed the "virtual currency" instry chain represented by bitcoin. This is a change in the financial instry and a new proct of the combination of the financial instry and the Internet. It represents a financial milestone in the new era and marks a new chapter in the history of the Internet. Bitcoin fund is one of the derivative procts represented by bitcoin in the era of "virtual currency"
according to the relevant news reports of Fuhui China, bitcoin fund will be open for operation in the autumn of 2014. Fuhui bitcoin fund, as the world's first operation mode of mutual benefit and win-win with financial management mode, is original and full of temptation and challenge
Unfortunately, bitcoin is no longer tradable in mainland China. Bitcoin China announced that it will stop all trading business on September 30, 2017
development information:
after bitcoin China and microbit, the bitcoin trading platforms in Shanghai and Shenzhen, respectively announced that they would close their trading business on September 30, 2017, on the evening of September 15, two other large domestic bitcoin trading platforms, Huo coin.com and okcoin.com, headquartered in Beijing, announced that they would suspend their registration from 21:30 on September 15, 2017 RMB recharge business; All users will be informed before September 30 that they are about to stop trading, and the trading business of all digital assets against RMB will be graally stopped before October 31
according to worldcoindex data, since September 1, bitcoin has dropped from $4800 to $3655, a drop of 24%, and its market value has shrunk by nearly $20 billion
in the same period, the decline of ether currency and Wright currency was 37.5% and 31% respectively. Over the past two weeks, Leyte currency has declined by more than 40% on the three major domestic trading platforms
today, the price of bitcoin once reached 50000 yuan, which fully shows that "bitcoin does not necessarily need China, but China seems to need bitcoin". Closing the Chinese exchange is not the end of the world for bitcoin. Many friends think that it is impossible to use RMB to buy and sell bitcoin now. In fact, it is still very simple to use RMB to buy and sell bitcoin now. Where there is demand, there is market
I personally used localbitcoins, a foreign trading website, a long time ago. It is similar to Taobao. The buyers and sellers registered on it are all indivials. When trading, the credit is guaranteed by localbitcoins. According to the customer's requirements, I choose the above trading list. The system supports the buyers and sellers to chat and exchange
for example, choose RMB to buy bitcoin, you can use Alipay and bank card transaction to complete payment. After receiving the payment, the seller will release the bitcoin frozen by
LocalBitcoins. If the seller does not release, it can submit evidence to the platform arbitration, usually there will be no problem. When choosing sellers, pay attention to choose sellers with high credit value, high evaluation and large historical turnover, and there will be no problem
local bitcoins is a person to person trading platform with a long history, which supports the legal currencies of most countries in the world: pound sterling, US dollar, euro and RMB. In the past, the volume of renminbi transactions was small, but recently, because of the closure of the central exchange in Chinese mainland, the buyers and sellers of RMB settlement became very much and it was easy to close. Besides, it is very convenient to pay and receive money with Alipay and bank card.
in addition to local bitcoin, okex, a subsidiary of okcoin, has recently opened C2C trading, which fully supports RMB trading (update: the point-to-point trading market of fire coin company has also been opened). Since the company is registered in Hong Kong and avoids mainland supervision, the mode is the same as that of local bitcoin. In addition, coincola and bitcoin world are the same person to person trading mode as local bitcoins, but I haven't tried. I don't know the depth of the transaction. With bitcoin, it's easier to trade other virtual currencies. The price of bitcoin is less than 1000 yuan four years ago. The current price of 50000 yuan is indeed high, but if the price of 100000 yuan next year, the current price of 50000 yuan is not high. Of course, no one can guarantee that the price will reach 100000 next year. In addition, you don't have to buy one bitcoin. Both 0.1 and 0.001 bitcoins can be sold
it must be pointed out that investment needs to be cautious, investment needs to be cautious, investment needs to be cautious! Don't understand and afraid of risk friends completely ignore. There are many ways to make money, and investing in cryptocurrencies such as bitcoin is just one of them.
bitcoin has entered the downward channel, showing a cliff like decline
since then, bitcoin has entered the downward channel, and the myth of bitcoin's sudden wealth is being shattered. According to the latest data of the "in depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, on June 25, bitcoin fell to US $6160. The previous trading day, bitcoin fell below US $6000, a new low in the past six months. Compared with the record high of US $19187 in December 2017, the decline was as high as 68%
the total number of bitcoin is 21 million. According to this estimate, the total market value of bitcoin in December last year was as high as US $402.9 billion, and now it has shrunk to 129.36 billion yuan. In the past six months, the total market value of bitcoin has evaporated US $273.567 billion, which is about 1.79 trillion yuan at the current exchange rate
at the same time, other cryptocurrencies also fell. Ethereum eth has dropped from a peak of $1350 at the beginning of the year to around $454.9 at present, with a cumulative decline of 66%. The LTC of Leyte currency dropped from the highest of $342.25 in December last year to the current $80.99, with a cumulative decline of 76.34%
the negative feedback of price decline is being transmitted in the instrial chain. Under the pressure of cryptocurrency market price, bitmain and Canaan, the top two Chinese manufacturers of bitcoin mining machines, may cut 50% of the orders of chip companies TSMC and Samsung Electronics
stricter supervision is a sign of chaos
stricter supervision worldwide is the main reason for the sharp decline of cryptocurrencies such as bitcoin
on June 22, Japan's Finance Department officially issued an order to improve the business of six cryptocurrency exchanges, including bitflyer, quoine, bitpointjapan, bitbank, btcbox6 and tech
Bureau
bitflyer, Japan's largest digital currency exchange, immediately suspended the opening of new accounts and carried out rectification, especially in its anti money laundering and control of terrorist funds. Japan has developed into one of the largest bitcoin trading markets. As soon as the news came out, the price of bitcoin fell to a new half year low
on June 10, coinrail, the cryptocurrency exchange of South Korea, said that its system had suffered "network intrusion", which also led to a sharp drop in bitcoin after its opening
judging from the change of regulatory attitude, countries have previously held an open and embracing attitude towards blockchain technology. However, with the rising price of bitcoin and the increasing use of ICO for illegal financing, the application of blockchain technology has "deteriorated", the speculative activities have increased significantly, and the cross-border capital outflow has been boosted, The attitude of regulators is also changing
the tightening of supervision will lead to the shrinkage of trading volume and the decline of activity, because the pricing mechanism of bitcoin price is highly positively correlated with the number of participants, which will lead to the decline of bitcoin price. Of course, we don't think bitcoin or digital currency will die out. As long as there is a trading caliber in the world, bitcoin will not die out. It's just a decline in valuation
blockchain technology - a potential change technology in the future
the "hype" capital of bitcoin represents the capital with strong risk preference in the financial market. Bitcoin is characterized by decentralization. As a distributed virtual currency, bitcoin is charged by users independently, and there is no unified regulatory core, such as the Central Bank of each major economy that supervises legal currency. Moreover, the development of bitcoin markets in different countries is different, so it is difficult to coordinate and supervise them. The characteristics of bitcoin make it more speculative
from the perspective of diffusion, bitcoin's recent sharp decline may be transmitted to risky assets such as stocks and commodities, which will depress the risk preference of the global capital market
block chain technology is not a bubble in itself, but bitcoin may be a bubble. Bitcoin is the first representative application of blockchain, but blockchain is not the same as bitcoin. The decentralized and distributed storage of blockchain technology has great application value. It is a potential new technology in the future. It is optimistic about the development of blockchain technology for a long time.
it is reported that in the special rectification work of the risk of non bank payment institutions, the central bank has severely cracked down on unlicensed institutions, rectified illegal trading venues, and "micro disk" transaction payment and settlement business, blocking the channels of illegal fund-raising; For the virtual currency trading places such as ICO and bitcoin, which are suspected of illegal fund-raising and securities activities, the central bank will timely issue an announcement with relevant departments to clarify the attitude, warn of risks, and deploy various regions to carry out rectification
the central bank said that in the next step, it will continue to do a good job in six aspects in accordance with the opinions of the State Council on further prevention and disposal of illegal fund-raising. First, it will cooperate with the Ministry of justice to promote the promulgation of the regulations on the disposal of illegal fund-raising and the regulations on non deposit lending organizations. Second, closely monitor the operation of private lending interest rates, guide the rationalization of private lending interest rates, uses and ways of borrowing, and rece the living space of illegal fund-raising activities. Third, continue to rely on the anti money laundering system to monitor illegal fund-raising. Fourth, we will continue to prevent and resolve Internet financial risks together with relevant member units of the leading group for special rectification of Internet financial risks. Fifthly, we should strengthen the construction of social credit system, build a joint incentive system for keeping promise and a joint punishment system for breaking promise, and create an honest and trustworthy credit environment. Sixth, continue to do a good job in protecting the rights and interests of financial consumers
according to the statistics of the joint conference office, there were 5052 new suspected cases of illegal fund-raising in 2017, involving 179.55 billion yuan, a year-on-year decrease of 2.8% and 28.5%. However, the total number of cases is still at a high level, the number of people involved in fund-raising continues to rise, cross provincial cases continue to occur frequently, and major cases involving many provinces and even the whole country still occur from time to time, and the overall situation is still grim.
since 2015, the price of bitcoin has been even worse. First of all, one of the world's largest bitcoin trading platforms has stolen $5 million worth of bitcoin from stamps. During the Spring Festival, biter, a well-known bitcoin company in China, and its piggy bank have been stolen, totaling more than 10000 coins. China's bitcoin circle is shrouded in a black cloud. The security of bitcoin has once again aroused everyone's attention. The confidence of bitcoin is also disappearing, and some big V's in bitcoin circle are also turning back
may 2015 be a turning point for bitcoin, or death or fire? Bitcoin has more analysis articles.
Bitcoin has become the most popular cryptocurrency in the world. Some countries allow the transaction of bitcoin, but some countries prohibit it. China belongs to the latter. Why does China shut down bitcoin trading? Let's analyze this problem today
bitcoin does not have the function of trading medium in China, so it can not be called currency. At the same time, bitcoin has the function of storing value and has certain investment value. However, the rapid rise of the current price has formed speculative anticipation and may form a bubble in the future. Therefore, it is necessary to take measures ahead of time, which can also restrain some illegal acts of laundering money and transferring assets through bitcoin. p>
