1.
The concept of 21 million
bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, 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
bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million
extended materials:
generation principle
starting from the essence of bitcoin, the essence of bitcoin is actually the 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[ 10] 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
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
2. 1. According to the bitcoin mining mechanism, it will eventually be infinitely close to 21 million, but it will never be reached
it can be roughly understood as the relationship between 0.9 (9 infinite cycle) and 1
2. Even if there is only one bitcoin left in the world, it means that there are 1000 0.1 bitcoins and 100000 0.01 bitcoins in the world
let's assume that the function of bitcoin is equivalent to that of gold as a currency anchor (in fact, it also has this function). You will understand that there are 21 million bitcoins in the world and only 0.1 bitcoins in the world are the same. The currency itself or bitcoin
for example, if the number of bitcoin in the world is reced to one tenth, the market price of bitcoin should be 400000 yuan (to understand this needs a certain economic basis)
so whether bitcoin is in circulation or not has nothing to do with the quantity.

3. Masturbation is not only a problem that can lead to fatigue, disability, madness and even blindness, but also a serious moral problem. It is a very special kind of human sexual life. In masturbation, the potential and unrestricted desire for pleasure collides with the restriction of social morality; Habitual actions and the desire to "do it again" challenge the restraint of conscience and morality
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

4. One of the controversial attributes of bitcoin is its fixed supply. At present, 25 new bitcoins are proced every 10 minutes, and the number is halved every four years. Overall, there won't be more than 21 million bitcoins & gt;. On the other hand, each bitcoin can be divided into 100 million shares (each is called 1 "cong"), if one cent is enough to buy a car, it will be troublesome to trade in US dollars, but even if bitcoin rises to the level of US dollars assumed above & gt; We will not encounter such problems. Therefore, in short, the total number of monetary units that will always exist is 2100 billion, that is 2100 trillion, or 250.899. In the square of choosing this value & gt; In fact, Nakamoto is much luckier or smarter than most people realize. First of all, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, & gt; The value will return to zero like a odometer
secondly, however, there is a smaller threshold for the total number of "smart": the largest possible integer that can be represented in floating-point format. Integers are not the only numbers that computers can store; To deal with decimals, computers & gt; Use a format for floating point representation. Floating point notation is essentially a binary version of scientific notation. For example, here is a value you will encounter when you study physics:
mass of the earth: 5.972 1024 kg
mass of the sun: 1.989 1030 kg
speed of light: 2.998 108 M / s
light year: 9.460 1015 m
mass of proton: 1.672 10-27 kg
Planck length: 1.616 10-35 m
we can notice that, How does scientific notation allow you to represent all of these values with reasonable accuracy, even though they vary greatly in size. Floating point notation is essentially a binary scientific notation; When you store numbers & gt; When the word is 9.625, what your computer stores is "1.001101
* 1011" (in other words, it stores 0100000000100011
& gt; This is the same thing with high-precision sequence form). In this high-precision form, the coefficient (that is, the part that is not the exponent) has 52 bits. This means high precision (more refined & gt; Double precision floating point number is enough to store up to 253 numbers, but it can't be any higher. If it exceeds 253, you have to start cutting off the numbers at the end. Bitcoin's 250.9, the total number of "smart" in the form of index, is just & gt; OK, below this maximum
if we have integers, why should we care about floating-point values? Because more high-level programming languages (such as JavaScript) do not open low-level "floating point" and "integer representation", but only provide "number" representation for programmers; Concepts
– of course, in floating-point form. If Nakamoto chose 210 million instead of 21 million at that time, bitcoin programming in many languages would be much more troublesome than it is now
note that Stefan Thomas unfortunately didn't notice this in time when he wrote bitcoinjs, so that the library used a special "big number big
number" object instead of an ordinary number to store the tutorial output value; My own bifurcated bitcoin JS (along with other improvements) uses ordinary numbers.

5. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. By 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes.
6. There are not so many bitcoins in the world for you.
7. It's an archaeological problem. According to the latest data of Hufu, a bitcoin is about 35000 dollars.
8. 21 million? There is no upper limit. Who can play with you? How can the price be speculated.
