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. People who study economy and currency understand that anything that shakes the monetary base of a country will be "disposed of". Bitcoin itself has neither real value nor credit guarantee (the US dollar has become the world currency because it is backed by the strong US government and 11 aircraft carrier battle groups). Bitcoin also wants to escape the supervision and control of the national machine, From another angle, you are a national currency issuing institution. If someone wants to challenge your position, what will you do?? Bitcoin, speculation is OK. If you really invest it as currency, you have too much money to spend! Unless: the state recognizes bitcoin as a legal currency, and there is a linked security system, or bitcoin will live in the "underground" honestly!
3. As a bitcoin player, after watching this issue of Caijing Lang Yan, I feel that it is necessary to correct Professor Lang's unprofessional knowledge of bitcoin:
1. Bitcoin allocation mechanism:
the mining allocation mechanism of bitcoin is not that 50 out of 10000 people (that is, miners) are divided into 50 bitcoins, but that only one out of 10000 people can get 50 bitcoins
it sounds unfair, but the existence of a mine pool is equivalent to a group of miners digging for bitcoin. If 10000 people form a team, any one of these 10000 people gets 50 bitcoins. According to the team agreement, everyone shares equally according to their contributions. More work pays more, less work pays less. The income from more contribution is more than 0.005, and the income from less contribution is less than 0.005, And as long as there is contribution, no matter how bad the computer is, it will have income (just can't make ends meet), forming a relatively fair distribution mechanism
2. Is bitcoin a currency?
bitcoin, as its English name is bitcoin, has never claimed to be a currency, but a payment system or accounting unit similar to a coin. Now it is meaningless to discuss whether bitcoin is a currency. Currency is a commodity separated from commodities and used as a general equivalent
the development of bitcoin is still in the process of practice, and it is far from being separated from commodities and becomes a fixed general equivalent. If it fails in the fixed experiment, bitcoin is not a currency; If it succeeds, bitcoin will be the historical alternative to legal currency. The good news is that the experiment has a trend of success so far
3. The intrinsic value of bitcoin
in the program, the CEO of bitcoin China couldn't answer the intrinsic value of bitcoin, but used an ambiguous price to refute, even angrily asked if you want 100 bitcoins, and was defeated by Professor Ying. I admire Professor Lang's wisdom, but I also regret that Professor Ying has no relevant computer knowledge and does not understand the intrinsic value of bitcoin
back to the point, what is the intrinsic value of bitcoin
bitcoin itself is worthless. It's just a string of codes, a number for bookkeeping. It's worthless, but the price is outrageous
what is really valuable is the bitcoin protocol! But this agreement is open all over the Internet
for example, there is a price for domain names on the Internet. A good domain name is still very expensive, but the domain name is just a string of characters and has no value. The whole Internet is used arbitrarily. The Internet all over the world uses exactly the same internet protocol. Only on top of the protocol can there be a large number of domain names. However, the internet protocol has become the cornerstone of human information society, on which many high price services are derived
it's amazing that those with value have no price, while those with super high price have no value
to explain the value of bitcoin protocol in one sentence: the honesty of payment between people is entrusted to mathematics and supervised by the whole network
you may not believe the person you trade with, he may cheat you, but you can believe that 1 + 1 is always equal to 2
bitcoin is characterized by decentralization, constant total amount, impossibility of counterfeiting and simplified proceres
4. Bitcoin connection problem
the program repeatedly talked about who is more stupid than bitcoin and who will play the last connection game
when bitcoin was first invented, I don't know if it was for your wealth, but with the development of bitcoin today, people who exchange legal money for bitcoin are really trying to win more wealth. Those who own bitcoin in the early stage earn those who enter the market in the later stage. The people who enter the market now also want to earn money from those who enter the market in the future. Let's imagine that the last one who comes into the game can't make any money if he has bitcoin and has no family. Moreover, the development of bitcoin has been as I said before. We all know the characteristics of bitcoin, but what choices do bitcoin owners have at this time
A. keep holding against inflation - the price of bitcoin is stable at a high level (because no one takes over)
B. throw bitcoin around - the price of bitcoin drops
C. exchange commodities with the merchants who accept bitcoin - the currency of bitcoin
in view of these three situations, let's think again
a. the price is stable at a high level, indicating that there is no large-scale selling, the price of bitcoin is stable, there is no inflation, and wealth is not plundered implicitly, which makes it a general equivalent suitable for money. Because the legal currency will be graally abandoned in devaluation, bitcoin will win completely
B. the price of bitcoin drops sharply. During the slump, there will be countless people waiting for the bottom, because we all know that the agreement of bitcoin is anti inflation, and it is worth preserving compared with legal currency. Therefore, people who didn't have time to buy coins at a low price in the early stage will continue to buy bitcoin until bitcoin drops to the bottom, and the bottom hunters will rush on, eventually making bitcoin a higher price commodity, Become the last runner of the new bitcoin. And this answer is also contrary to the assumption of the last one who came into play before us
C. bitcoin, as a supplement to legal currency, acts as a general equivalent
to sum up, if bitcoin is likely to develop normally, it will go through the process of becoming a supplement to legal currency, and then replace legal currency to become a currency. Of course, this is an extremely long and difficult process, and it may also fail
5. The concept of Chinese aunts in bitcoin
specifically refers to a group of Chinese retail investors who rush to buy gold ring the gold price crash in 2013, because in China, the main consumer group of gold is aunts, who have the capital strength, no relevant knowledge and experience, and the courage to make crazy investment
ring the period of the sharp rise and fall of bitcoin, the concept of Chinese aunt speculation on bitcoin also spread
according to a large number of statistics, 93.6% of bitcoin players are male, and they are 20-40 years old, and most of them have bachelor's degree or above. Of course, quite a few of them have financial strength, no bitcoin related knowledge and experience, and have the courage to make crazy investment. If people with these characteristics are called Chinese aunts, they are indeed a cold joke
according to this concept, the CEO of bitcoin China who argued with Professor Lang in the program also belongs to the group of Chinese aunts.

4. Professor Lang Xianping warned: bitcoin is a complete financial fraud. People should take care of their wallets, cherish their lives and stay away from bitcoin
everyone has his own views on new things, which can not be covered in a word. Everyone has their own theoretical basis, but whether bitcoin is a fraud still needs to be tested in practice. There is no right or wrong point of view, and practice is the only standard for testing truth. Bitcoin is just a small-scale social experiment. However, with the rising tide of bitcoin, many well-known counterfeit coins have been derived, such as Wright coin, dog coin, Ruitai coin, Weimeng coin and so on. However, pyramid schemes under the guise of digital currency are also increasing.

It was in 2017 that China announced that bitcoin trading was not allowed in China. Overnight, all exchanges withdrew from the Chinese market. Because of this news, bitcoin once plummeted. This is the general 94 event
e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million
in other words, the bitcoin system can be self-sufficient, resist inflation through coding, and prevent others from destroying these codes
expansion data:
bitcoin price bubble exists, it is a problem that need not be discussed. Whether from the increase or from the value of the currency itself, bitcoin is bubbly. p>
its so-called advantages, such as scarcity, fidelity, strong liquidity, transparency and decentralization, are just the cover of speculation, which can not support its roller coaster like rise. Today's slump is telling
7. The strange fate in the sleeve "Acacia dream": tears flow first without plucking the strings, separated by high walls in the deep courtyard; When and where can we meet? Broken cloud resial rain sorrow, lonely day and night; A song tonight, a broken soul is willing to enter the dream of a husband.

According to the data of coinmarketcap.com,
on March 12, 2020, the trading volume of bitcoin in the whole network reached 8.44 million
on March 13, 2020, the transaction volume of bitcoin in the whole network reached 14.91 million
as of March 20, 2020, the total transaction volume of bitcoin in the whole network has reached 77.5 million in the past nine days< br />
