BTC time dial
It was officially born on January 3, 2009
since 2015, the future of bitcoin has become more and more uncertain. On the one hand, bitcoin fell as much as 55.55% against RMB last year; In 2015, bitcoin fell by more than 30% against the RMB in the first half of January alone
bitcoin's "falling" reflects the "self-healing" of its value after "fanaticism" to a certain extent. According to statistics, in 2013, bitcoin rose from 1 ∶ 13.59 to 1 ∶ 731, with an annual increase of 5300%. This speculative driven inflation has affected the virtual currency property on which bitcoin relies
on the one hand, no country has defined it as a legal currency. On the other hand, in 2014, the US dollar rose significantly, and the prices of oil and bulk commodities fell correspondingly. The price trend of bitcoin is the same as that of the latter, becoming part of the asset allocation of some speculators, which highlights that its asset attribute is far greater than the monetary attribute
extended data
Security and credit risk have also become the reasons for the decline of investor confidence. Mt. GOx, once the world's largest bitcoin exchange, claimed in March last year that it had lost all its assets e to hacker attacks. Recently, it was revealed that its lost bitcoin was probably e to internal system manipulation
the regulatory environment of bitcoin is not optimistic, and Russia, Thailand and other countries have begun to implement strict control on it. In addition, the global stock market performed well last year, resulting in the diversion of bitcoin investment funds, and the crazy "mining" activities also rapidly increased the supply of bitcoin, which may lead to a trend of oversupply in the short term, leading to a sharp drop in the price of bitcoin
When bitcoin first appeared in 2009, its price was less than 1 cent. One dollar could be converted into 1300 bitcoins, that is to say, seven yuan could be converted into 1300 bitcoins
on May 5, 2017, bitfinex, an overseas digital currency trading platform, quoted a price. Bitcoin once hit US $1700, about RMB 11737
extended information:
in China, some Taobao stores have also begun to accept the use of bitcoin, and businesses will graally increase
in October 2013, the first bitcoin quarterly, one bit, was released
on October 15, 2013, the network accelerator service of the network announced its support for bitcoin
on October 26, 2013, btcmini reported that GBL was hacked
on October 31, 2013, Lei Teng, a famous Internet lawyer, proposed the event of "filing a case to investigate the closure of GBL bitcoin trading platform as soon as possible", analyzed the "value function" and "use function" of bitcoin, and bitcoin should be governed by relevant laws
on December 5, 2013, notice of the Ministry of instry and information technology of the people's Bank of China, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing bitcoin risk: bitcoin is a specific virtual commodity; Bitcoin trading is a kind of commodity trading on the Internet. Ordinary people have the freedom to participate in it at their own risk
on September 4, 2017, the announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risk of token issuance financing: it is prohibited to engage in token issuance financing activities (ICO)
the trading platform shall not engage in the exchange business between legal tender and token, or virtual currency, or buy or sell token or virtual currency as a central counter party, or provide pricing, information intermediary and other services for token or virtual currency
on November 2, 2018, the people's Bank of China released the 12th topic of China financial stability report 2018, which talked about "encrypted assets"
Bitcoin network generates a new block every ten minutes. Every time a miner completes a block, he can get a certain amount of bitcoin as a block reward, and the reward will be halved for every 210000 blocks mined. Because the time for mining each block is limited to 10 minutes, at this rate, the period for the reward to be halved is four years, that is to say, the reward for bitcoin blocks is halved every four years
when the bitcoin block reward was halved for the first time, its price rose 25 times from 300 yuan to 7995 yuan; In the second half, the price rose 28 times from 5011 yuan to 140000 yuan. So many people predict that the third halving of bitcoin in May 2020 will lead to a sharp rise in the price of bitcoin, at least 10 times. However, these figures are not so clear. After halving in 2012, bitcoin prices rose for two months, and in 2016, there was almost no immediate response to deflation for a month. This may also be the result of the strategy of "buying rumors and selling news" implemented by some speculators
extended data:
after bitcoin halved, the supply slowed down, and keeping deflation through algorithm has always been a part of bitcoin protocol design. It was set up to ensure the value of bitcoin. By recing block incentives and setting the maximum possible supply of bitcoin at 21 million bitcoins, bitcoin has an anti inflation feature, which runs counter to the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation, and less than 3.5 million bitcoins are available for mining. When the next block award halves, bitcoin's annual inflation rate will drop from the current 3.8% to about 1.8%
maintaining deflation through algorithms has always been a part of the design of bitcoin protocol. It was created to guarantee the value of bitcoin. By recing block incentives and keeping the total amount of bitcoin at 21 million bitcoins, bitcoin is endowed with an anti inflation nature, which is different from the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation and less than 3.5 million available for mining. The next block award cut in half could rece bitcoin's annual inflation rate from the current 3.8% to about 1.8%. This will be the first time in bitcoin's history that it has fallen below the historical average of about 2% - 3% growth in gold supply
masturbation is a self defiling behavior. This is an unnatural behavior that exists in both sexes. The perpetrator can molest his body without passing others. Through various unclean fantasies, they intend to imitate and obtain the supreme happiness of the senses. Masturbation is vulgar and shameful in modern history Here, even for a brief moment, desire and fantasy drown morality and principle; Strong self-consciousness breaks through the wasteland of sexual desire and enters into a luxurious world imagined by masturbators themselves. For a long time, masturbation has been hovering between social disdain and self satisfaction
masturbation is a bad habit of civilized society, and the only way to escape self-restraint mechanism and seek happiness: masturbation can't be stopped and restrained, when men and women are completing their sexual enlightenment, then masturbation is used to relieve sexual desire and "rape their own bodies." The medical profession has summed up a long list of symptoms caused by masturbation, including tuberculosis, epilepsy, papules, madness, general emaciation, and premature death. Masturbation is "far more terrifying than smallpox."
the consequences of masturbation will be as described in the Bible - death. Death is not God's punishment, but comes from the twisted nature of masturbation. In a sense, masturbation and other subsequent behaviors have largely confirmed Freud's theory that it is easy to commit a crime, but it is difficult to erase the mark of crime. The idea that masturbation will not be detected and punished is a complete illusion
whatever the reason, masturbation is a very popular behavior, because people who inlge in masturbation do not know that they are carrying out wrong behavior, and think that this kind of behavior is not constrained by conscience and society, and will not lead to serious consequences. So masturbation is a pleasure of falsehood, a reversal of reality, so it is dangerous and needs to be strictly prevented. Masturbation is a kind of harm to health, reason and marriage, even to self pleasure
it can be seen that ignorance is an important reason for the widespread masturbation. As a result of debauchery, loneliness and boredom, or through the guidance of peers, some young people begin to learn to inlge themselves by masturbating, but they don't know that this behavior is not only wrong, but also extremely harmful. One reason for ignorance is that masturbation is not known. Other unclean behaviors are often detected, while masturbation is not. People who masturbate don't need to feel shame or guilt, and they won't be restricted by traditional morality
masturbation, a "deceptive vice", is "the most harmful of all behaviors". James Paget, Queen Victoria's doctor, wrote in 1879 that the harm of masturbation is actually a form of sexual hypochondria. Dr. Paget also deplores this behavior. Masturbation, he said, is a sinful act, "dirty, unclean, morally corrupt, and abandoned by both man and God."“ Playing with your body "and so on
masturbation is a sign of self depravity and self despair. This new sexual vice is more attractive to people than any other behavior. It's particularly worrying because people who engage in this kind of behavior think they can go unpunished - "masturbation in particular" is not easy to detect. All men and women are more likely to succumb to masturbation than other sexual vices
a case experienced by Professor Frederick Hoffman of Harley University in Germany. Professor Hoffman is famous for the theory of "essence Qi". He believes that there is a fluid like "essence Qi" in the human body, which is transmitted from the nerves to the muscle tissue and maintained in a state of contracture. This view is widely spread, and that masturbation e to excessive loss of "essence", so it will lead to mandibular relaxation, weakness and other symptoms
masturbation is the total negation of all good things in human sexual life, which causes serious consequences and is the root of all evils, moral corruption and deviance. Fowler, a skull physiologist in the 19th century, wrote a book, which said that masturbation is "the sin of sin, the evil of evil", which will lead to countless "sexual corruption, impotence, various diseases and moral corruption, the total number of which is far more than the sum of other abnormal sexual behaviors". Although Fowler does not deny that this kind of behavior proces self pleasure, others do not. Dr. Kellogg, the founder of the cereal Kingdom and the founder of the famous health care reform movement in the United States, believes that masturbation is the worst of all human sexual quirks. He made no secret of his aversion to masturbation. He called masturbation "the great enemy of mankind" a more "abominable evil" than the "ugly act" of private sex trading
Lord badenberg, the founder of the boy scout movement, said that if this "obscene" behavior becomes a habit, it will soon "destroy people's body and spirit". Those unfortunate people who are tortured by this kind of behavior will eventually be doomed to "enter the madhouse". In the foreword of another widely circulated pamphlet, the leader of the boy scouts in the United States warned that he had witnessed a boy about 12 years old who had to be sent to a madhouse for excessive masturbation. There is almost no cure for the disease. Even older boys are not immune
the book warns everyone that improper playing with private parts will lead to mental disorder, which should be resisted by any normal male. Girls were warned more seriously. If they masturbate, they will have a complete mental breakdown. They will not only be sent to a madhouse like boys, but also be likely to die early. The pamphlet was highly recommended by the president of the Social Health Association of the American women's Club Federation
it is immoral to let the serious consequences of lack of sexual restraint spread, and such a harmful behavior, that is, the unnatural behavior of masturbating to obtain satisfaction, is by no means the solution to the problem. Masturbation is a kind of "depraved behavior deviating from social morality". It does not bring "spiritual relief" to the perpetrators. On the contrary, it makes the perpetrators "physically and mentally damaged, and even lead to mental disorders". The consequences of masturbation are "heinous."
masturbation is the most terrible of all sexual instincts. The basic purpose of sexual intercourse is to breed healthy offspring, so masturbation will not only have fatal consequences on the indivial's reproctive capacity, but also harm the society. There was such a warning in a western sexual health guide that once people "violate the laws of nature", they will lose their reproctive capacity forever. Masturbation is not only harmful to the muscles and nervous system, but also morally debilitating for those reckless teenagers who practice it. Therefore, the guide suggests that in this era of indivialism, people must realize that only they can achieve self salvation
Professor Stanley hall, President of Clark University (the first university in the United States to invite Freud to give a lecture), who can be regarded as the originator of adolescent psychological research, once said that "masturbation is the most heinous behavior" and "the most tragic aspect of human weakness, and the culprit of a series of neurological and cardiovascular diseases". This remark is still popular with many people. In his view, masturbation is the root of all major crimes, whether social or personal
the fundamental problem of masturbation lies in its self satisfaction. It makes it possible for people to fantasize about unrestrained sexual enjoyment without anyone or anything, because all the necessary things - desire and satisfaction - exist in the indivial itself“ The masturbator always has the necessary means, tools and motives to carry out this crime. "“ There is no reason, as long as you have this idea, you can arbitrarily allow your body to be manipulated by pornographic desire; It's fantasy, not nature, that dominates them. "The consistent practice of preventing a certain evil from happening - avoiding temptation
masturbation, which is completely caused by internal behavior, has almost no effect at all. On the contrary, masturbation is generally considered rampant because of its incomparable attractiveness and no way to restrict it. Moreover, since masturbation is always carried out by indivials in private, for some people, it seems to be the only vice that can escape social condemnation without punishment
this "dirty and disgraceful trick" not only makes the body weaker, but also makes the brain more and more ll. This kind of behavior of self satisfaction pollutes people's brain very early. "Masturbation, an indivial vice, has become a public hazard for all mankind."
for masturbation, we need to constantly criticize, condemn and warn. We should not only rely on external restraint force, which has no effect on this kind of evil behavior, but also self-restraint through our own sense of shame and guilt. This sense of shame and guilt is cultivated by constant ecation. In essence, masturbation, once acquired, is addictive. Therefore, this kind of behavior needs constant criticism and condemnation. Masturbation is often compared to smoking. In order to satisfy the endless self desire, people who inlge in these two kinds of bad habits will fall deeper and deeper
because there is no other vice that is more alluring and easier to carry out than masturbation. It can be implemented quietly without any external force, and the chance of masturbation always exists. It is not monitored by the public at all, because it is quite easy to be unknown. What's more, in the real world, the methods that are usually used to prevent evils have no effect on prostitution, and the laws of hindrance and inertia do not apply
since masturbation is often carried out alone and in private, it is entirely possible for this kind of evil behavior to imprison people's soul. It is too late for masturbators to realize the harmfulness of this evil habit. They try their best to get rid of this bad habit, but they always fall into it again. Masturbation, like drugs, makes masturbators addicted and unable to extricate themselves. Like heroin and other lethal drugs, masturbation will make countless innocent people become addicts step by step
masturbation is completely caused by people's inner desire, only shame and guilt

it is estimated that 21 million pieces will be excavated in 2140

according to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow any more. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, the "proction time of each block is 10 minutes" used in the above calculation method is an ideal state, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error
the shortcomings of the above methods are that they can not accurately predict the change of bitcoin network computing power and the mining speed of bitcoin. The 11.3-day data used in the above calculation method is only the average value from May 2013 to April 5, 2014, and the representativeness is questionable. We can integrate the results of big data analysis and mining machine proction to establish a more accurate mathematical model
