Reasons for ban of bitcoin

1. In June 2011, Symantec issued a warning that botnets are participating in bitcoin; mining & quot; In the middle. This can take up the computing power of the victim's computer, consume extra power, and cause the temperature of the host to rise. Later that month, ABC found an employee using the company's server to mine
some malware also make great use of the parallel computing power of graphics cards. In August 2011, botnet of bitcoin mining was discovered, and Mac OS X infected by Trojan horse was also discovered to mine bitcoin.
on June 19, 2011, security vulnerability of mt.gox (Magic: abbreviation of the gathering online exchange) bitcoin trading center caused the price of 1 bitcoin to drop to 1 cent (although other transactions were not affected). The reason is that a hacker stole the user's mtgox certificate from the computer infected with the Trojan horse, so he transferred bitcoin to his own account and sold it, resulting in a large number of "ask" requests at that price. A few minutes later, mtgox shut down and cancelled the abnormal transactions in the hacking incident, making the price of bitcoin rebound back to $15. In the end, the bitcoin exchange rate went back to what it was before the crash. Accounts equivalent to more than $8750000 were affected
in July 2011, the operator of bitomat, the world's third largest bitcoin trading center, announced the loss of access rights to the wallet.dat file that records 17000 bitcoins (about 220000 US dollars). At the same time, announced the decision to sell services to make up for the loss of users
in August 2011, mybitcoin, one of the processing centers of common bitcoin transactions, announced that it had been attacked by hackers and shut down. Involving 49% of customers' deposits, more than 78000 bitcoins (then equivalent to about $800000) are missing
in early August 2012, bitconica was sued in the San Francisco court for damages of about $460000. In 2012, bitconica was attacked twice by hackers, accused of ignoring the security of customers' funds and forging withdrawal applications
in late August 2012, bitcoin savings and trust was shut down by its owner, leaving about US $5.6 million in debt. At the same time, he was accused of operating the Ponzi scheme. In September 2012, the securities and Exchange Commission began to investigate the case
in September 2012, bitfloor trading center was also hacked, and 24000 bitcoins (about US $250000) were stolen. Bitfloor was suspended. Bitfloor resumed operations in the same month, and its founder said he had reported the theft to the FBI and that he was planning to compensate the victims, but the compensation schele was unclear
in June 2011, a hacker transferred 25000 bitcoins into his account, which is equivalent to 500000 US dollars. The whole transaction could not be traced. Although the owner of bitcoin announced the theft on the Internet, it was useless. The hacker became the first thief of bitcoin
in 2012, 46703 bitcoin worth US $228845 was stolen e to the disclosure of the super management password of the server of the website hosting provider linode. More than 43000 stolen bitcoins belong to bitcoinica, a bitcoin trading platform. Another 3094 bitcoins are owned by Marek palatinus, a Czech programmer. Gavin Andersen, the chief bitcoin programmer, also lost his five bitcoins.

2. Most of the reasons for the title can be solved. Of course, self-help is no good. It can be solved through channels or appealed

3. The most direct cause of the crash: the bitcoin exchange MT GOx was attacked by hackers, causing a lot of panic selling of bitcoin by investors
in addition, the underlying reason is that the world does not recognize the monetary payment property of bitcoin, but regards it as an investment commodity similar to gold, and even has large-scale capital participation in speculation.

5. At present, it is still too young and needs to be developed for some time (the technology is not mature and can not be widely used)
it's also a problem to be unable to control, otherwise there will be big problems (for example, the asset transfer of dog officials can't be traced.)

6. The people's Bank of China banned financial institutions from trading in bitcoin, saying that bitcoin is not a "real" currency. As far as the investment risk of bitcoin is concerned, the government's view may be reasonable
the media's hype about bitcoin has made more than one newspaper sneer: "at present, journalists recognize bitcoin more than investors as a reliable way to store wealth." Government departments around the world are also paying attention to bitcoin. Although the Chinese and American governments have not banned it, they do not encourage people to participate in it. Here we focus on two questions: why is bitcoin so important? Why doesn't the government like bitcoin

bitcoin is a virtual payment system, which is not controlled or governed by any central government or private institutions. Unlike Alipay or Paypal, the system has its own monetary unit (bitcoin) instead of Renminbi, US dollars or other legal tender. Strictly speaking, bitcoin has no physical form. Instead, it trades over the Internet, and users store their bitcoin in their wallets. The bank account books record the depositors' deposits and withdrawals. The public can not see these records, but it is legal for the government to ask to review these records. The account book of bitcoin is called "block chain". In theory, it is a public document (anyone can download a ), but the participants of bitcoin system can easily hide their identity, because bitcoin is sent to the address randomly generated by electronic money package, which is composed of letters and numbers. In other words, I can provide a new address for each transaction. So even if people can figure out how much bitcoin they can get, they won't know if I have bitcoin

Where can I get bitcoin? One way is through "mining.". This method is by no means easy, and the computing power required for "mining" is now more than most people can afford (according to the design of bitcoin system, it will be increasingly difficult to find bitcoin). I know it's too simple to say that. The fact is that bitcoin's revenue and expenditure books are jointly maintained by "miners" all over the world. Most of the "mining" groups (more than 60000 users) that "miners" participate in spend a lot of time and power, and some of them can get bitcoin. For the majority of non professionals, it is much easier to buy bitcoin online on the bitcoin "exchange" with regular currency. Until recently, Japan's Mt. GOx was the world's largest bitcoin "exchange.". In China, bitcoin "exchange" BTC China has the longest history
I'm not surprised that China has quickly become a major bitcoin market because bitcoin has performed so well as a private trading channel. It is estimated that in 2013, the trading volume of bitcoin in China (including Hong Kong) accounted for more than half of the global trading volume, and more than 100000 bitcoins were traded in "bitcoin China" every day. People's interest in bitcoin has increased greatly, especially in China, which has led to a significant increase in the value of bitcoin, from about $0.08 in June 2010 to $1124.76 in November 2013. This led to reports that a Norwegian man bought 5000 bitcoins for $26.60 in 2009 and sold them for $886000 in 2013
unfortunately, those who bought at the peak have found that their bitcoin has almost halved in value - the current price of bitcoin is less than $600. What's wrong
for some investors, it is a problem that bitcoin has no physical form. For example, the Norwegian man mentioned above forgot his e-wallet password and had to take great pains to delete and rebuild it. Mt. GOx is much larger. It stopped trading on February 25, 2014, and then filed for bankruptcy protection in Japan and the United States because it lost about 550000 bitcoins, which were worth $473 million at that time, accounting for 7% of all bitcoins in circulation. Attorneys for Mt. GOx said in court that the reason for the loss of the bitcoin may be that "there is an algorithm defect in the bitcoin software, and someone has used this defect to invade the bitcoin network.". Investors usually stay away from such risks that they cannot understand
however, the bigger problem with bitcoin is that the Chinese and US governments are not friendly to bitcoin. In December 2013, the people's Bank of China banned financial institutions from engaging in bitcoin trading, saying that bitcoin is not a "real" currency. The bank made it clear that investors were free to participate in bitcoin trading, but at their own risk. Analysts pointed out that the Chinese government is worried that bitcoin trading by financial institutions will threaten the government's control over the financial instry, especially in terms of money supply and cross-border money flows. Before too many parts of the economy become "invisible" and untraceable, the Chinese government must act< Almost at the same time, U.S. Department of Homeland Security agents detained more than $5.1 million of bitcoin in Mt. GOx's account. They said the money came from a criminal network called silk road. In January 2014, a director of MT GOx was charged with money laundering. However, the U.S. government did not declare bitcoin illegal. Instead, after explaining the tax law, it used an unconventional means to punish users of bitcoin. In March 2014, for example, the Internal Revenue Service announced that bitcoin was an asset, not a currency. This has a significant impact. For example, if an American taxpayer buys $500 of bitcoin and then uses them to buy $1000 of goods e to the rising market price of bitcoin, he has to pay tax for his income. If the taxpayer purchases foreign currency, he does not need to pay tax when the foreign currency appreciates against the US dollar. In addition, bitcoin miners must declare the value of bitcoins by the date they were discovered, not by the time they were spent. In other words, bitcoin related taxes need to be paid immediately, even if the "miner" intends to keep these bitcoins for a few years. Recently, the U.S. government announced that it would transfer the bitcoin detained from "Silk Road", but asked the buyer to show his identity, which would inevitably weaken people's desire to buy and rece the transfer price of these bitcoins

since December 2013, China's official attitude towards bitcoin has not changed. However, the Chinese government does not allow domestic banks to do business with bitcoin "exchanges", especially in transferring RMB deposits from personal accounts to "bitcoin China". On April 28, 2014, bitcoin China said on its microblog that its user account had voluntarily stopped accepting RMB deposits. Since then, China has not encouraged bitcoin "exchanges" to allow users to withdraw Renminbi from their accounts. The future of bitcoin in China is not good, only Hong Kong may be an exception; At the same time, there are bitcoin ATMs in Hong Kong
but as far as the investment risk of bitcoin is concerned, the government's view may be reasonable. Recently, it has been reported that a "mining" group has controlled more than half of the bitcoin computing power, which may enable the group to veto bitcoin transactions verified by other "miners", or reuse the same batch of bitcoin without fear of being questioned. For most people, these problems can be too complex to solve. However, in mid June, Peter Chen, the main developer and advocate of bitcoin, made a breakthrough; Peter Todd, who sold half of his bitcoin, said: "I've learned that the factors that make bitcoin motivating are flawed, for a number of reasons. To say the least, even if only a few of the main reasons are taken into account, it will make people worried when a mining group controls 50% of its computing power. "
