Professor Lang Xianping 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.
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.
the issue on January 27, 2014
The following is Lang Xianping's original words:
"Goldman Sachs used to be the largest shareholder of ICBC, and its good friend Bank of America used to be the major shareholder of CCB. CCB's listing has made them 130 billion yuan, which means that every one of us pays 100 yuan for Bank of America. The financial reform, in the end, profited from Goldman Sachs Group
I really don't know how I calculated at that time and why I was led by Goldman Sachs. Recently, those ghosts have cashed out frequently and gained huge wealth from it. With their empty singing and multi singing, we are bewildered, and some so-called experts feel very good. These experts are just like the "black mouth" of China's stock market, carrying sedan chair for Goldman Sachs, and they even don't know that they have been used by Goldman Sachs. "
Global Times disclosed that Goldman Sachs had done some bad things in the world and China: "more than two years ago, the soaring prices of oil and other international commodities led to global inflation and the increasingly difficult economy of developing countries, which was directly related to the manipulation of multinational investment banks such as Goldman Sachs. Take the oil price as an example. Before the international oil price set a record of 147.27 US dollars per barrel in July 2008, the trend was almost consistent with the report released by Goldman Sachsa Chinese economist said that when China's state-owned banks were restructured in 2004, Goldman Sachs published reports one after another to slander China's state-owned banks, saying that they are not worth a little money, and that bad debts are too high, they are not worth money. Don't take them. But as a result, Goldman Sachs and others bought the listed shares of Bank of China at an extremely low price. With the listing of a state-owned commercial bank alone, Wall Street companies such as Goldman Sachs made 130 billion yuan, equivalent to 100 yuan given to the United States by each Chinese
"Zhou Shijian, a senior researcher at the center for Sino US relations at Tsinghua University, told reporters that Goldman Sachs has been disrupting the international financial order. In 2007, Goldman Sachs published a report that crude oil would rise to $200 a barrel. At that time, China desperately bought crude oil at $147 a barrel. Goldman Sachs also set up "gambling agreements" with some Chinese companies, but quietly sold crude oil itself. By the end of the year, oil prices had fallen to $34 a barrel. China's SASAC officials have said they reserve the right to sue Goldman Sachs and other trading frauds
some readers may remember that in 2008, today's quick review of our newspaper published a series of opinions on oil prices, the "theory of cheap selling of banks" and so on. At the end of the year, it made a summary with the title "why do you always cheat students" At the end of the article, I said, "in the" currency war "dancing with wolves, we lose more and win less. Teachers have responsibilities, and students have responsibilities. "
after reading the articles he wrote, it was just amazing and eye-catching. I didn't think he had much level.
there is a purpose to do things, and different purposes need different statements to support them. To make people believe your judgment, you need to be reasonable. That's more tenable
indivial investment in gold can turn 100000 into 300000, but don't think about turning 100W into 300W
this is the purpose.
