How do you sell bitcoin that you owned very early
The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed
the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history

users can buy bitcoin, and at the same time, they can "mine" bitcoin by using computers to perform a large number of calculations according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
from 2012 to 2014, bitcoin swept the world, and graally formed the "virtual currency" instry chain represented by bitcoin. This is a change in the financial instry and a new proct of the combination of the financial instry and the Internet. It represents a financial milestone in the new era and marks a new chapter in the history of the Internet. Bitcoin fund is one of the derivative procts represented by bitcoin in the era of "virtual currency"
according to the relevant news reports of Fuhui China, bitcoin fund will be open for operation in the autumn of 2014. Fuhui bitcoin fund, as the world's first operation mode of mutual benefit and win-win with financial management mode, is original and full of temptation and challenge

special attention:
1. When purchasing and selling bitcoin, it is necessary to deal with it in time, and do not need card orders. For example, after placing an order, you need to pay in time and click paid. After others pay you, you need to put money in time. Otherwise, the other party will appeal to Huo coin
2. The collection account must be filled correctly
3. The risk of currency market is high and investment should be cautious
after buying bitcoin, if you want to change it into other currencies, such as EOS and Ethereum, you can go to the currency trading platform and directly click the hanging order to sell it and change it into other currencies you want. If you want to change money, you can sell it on the off-site platform. People who need to buy will contact you, operate on the platform, and then pay offline< strong>
Those people are living a good life now, those who played bitcoin in the early days & lt; The pig of tuyere & quot; Made a lot of money
the discussion of bitcoin in many forums is no longer limited to & quot; Is bitcoin a scam;, Instead, it extends to & lt; Can bitcoin become a global currency in my opinion, bitcoin is a full digital bubble. A virtual currency constructed by algorithm has no national support behind it. Moreover, the scarcity of bitcoin will inevitably lead to its appreciation very quickly, especially under the guidance of market economy. behind the currencies used by countries in daily life are endorsements with national prestige, just like the reason why the US dollar circulates around the world is not because the strong national strength of the United States ensures the liquidity of the US dollar Nakamoto's original simple idea of letting bitcoin replace the currencies of various countries and become the object of global circulation is a joke in terms of power struggle between countriesBitcoin is just like the currency in the game, but no one releases bitcoin. Instead, it relies on a specific algorithm to generate , so now people looking for bitcoin also call themselves miners, but they rely on computers to mine
the rise of bitcoin is e to the restructuring of global risk assets , and the widening of investment channels for encrypted assets . Since the beginning of this year, the volatility of securities and foreign exchange markets has intensified, and global investors are looking for safe assets. Traditional safe asset gold is more dependent on the real economy and inflation expectations, Bitcoin is more like a sensitive index, gaining a certain asset hedging advantage
The wealth of Cameron Winklevoss and Tyler Winklevoss twin brothers has increased significantly. In April 2013, they held $11 million of bitcoin, which was then priced at $120. At this week's price of $11500, these bitcoins are worth more than $1 billion
first of all, bitcoin is not created one by one. Bitcoin is made up of one account book after another. As long as you can record one account book, the system will reward you accordingly (starting from 2009, after four years, one will reward 50 bitcoins, another four years, one will reward 25 bitcoins, and so on), Because the account book records the transaction information, the transaction fees generated by the transaction also belong to the bookkeeper. Such a good thing, of course, everyone wants to keep accounts. At this time, the more wonderful thing will come. The system will put a mathematical problem every ten minutes. Whoever works out first will have the right to keep accounts. They can keep accounts and get bitcoin generated by keeping accounts
then the generated bitcoin will be saved in your wallet address. You can transfer the bitcoin in the address to EXX. There are not only bitcoin, but also more valuable currencies. Of course, you need to choose
investment is risky, and we should cherish it

world wide steel, pseudonym, physicist and scientific author. He is the author of the best-selling book "never expected: understanding the world with science and engineering thinking". The purpose of his article is "understanding the world with science and engineering thinking". He likes science and politics, and emphasizes rationality and modernization
this is a preface written by world wide steel for the new book intelligentsia: being a complex modern man (Electronic Instry Press, February 2016). The surging news is published with the authorization of the author< This is a book about the modern world. I want to talk about something in this book that a modern person should have, and only a modern person can have; Wisdom & quot—— Wisdom and insight. If you want to understand the modern world and even make some decisions, you have to have this kind of wisdom
from the perspective of social change, the ideas to be discussed in this book are quite new, and they have not yet become idioms and allusions to be written into our cultural genes. They are scattered among the latest developments in various disciplines and are often unknown to laymen. But these ideas do not need any professional knowledge to be understood and mastered. They have been spread among scientists, philosophers, engineers, entrepreneurs, entrepreneurs, university teachers and students, and people in all walks of life who are sensitive and interested in the modern world
these people are not just traditional & quot; Intellectuals;, It's & quot; Intellectual elements & quot
I used to be a physicist. I made a living in scientific research, but my achievements have not reached the level of daring to speak Chinese; Physicist & quot; The degree of self assertion. It is reasonable to focus on physics research, but I read a lot of non professional books and wrote a lot of articles that have nothing to do with physics. I don't do these unprofessional things because physicists have more free time, but it's really because the turbulent modern world is so interesting - I even think that if you don't get to know the latest ideas of the world well and just satisfy yourself with being an intellectual in a specific profession, you will be born in the modern world for nothing
and you may be in danger of falling behind. There are three important trends in the world at this moment, which challenge us intellectually< The first is that the world is becoming more and more complex< Economists love to talk with pencils. A pencil seems simple, but if you think about it carefully, the graphite lead, the wooden shell, the metal skin and the rubber of the pen head, from the extraction of the primary raw materials to the processing and assembly, you don't know how many hands have passed. No one has mastered the whole set of pencils; Craftsmanship;, What everyone knows is just one step
Hayek tells us that this is the power of the market. In fact, knowledge is decentralized and distributed among people. It is the market that organizes people to work together. So if you only know the same knowledge, no problem, as long as you make a reasonable response to the price signal, you can live a good life. On the other hand, if someone wants to have all the knowledge, try to take charge of the whole situation and even make plans, he can only help
but the modern world is more complicated than the traditional pencil workers. If I'm a pencil worker with low salary but a little modern consciousness, I want to ask why I can't get high salary. I need to know something about economics. I would also like to suggest that factories print some words and patterns on pencils to promote sales, which probably involves psychology. I am concerned about the stability of my work. Some people say that the pencil instry is dying. How can I evaluate the credibility of such comments? Will I be replaced by robots? How should I engage in office politics with my boss? If I want my children to work at a higher level in the future, should I focus on exam oriented ecation or quality ecation
no one only knows to stare at price signals. These are the real situations of modern people: they face many problems every day. How to answer these questions? In fact, most people's way is to imitate others, because it's useless to think for themselves, and it's useless to watch the romance of the Three Kingdoms, the art of war, and the study of the thick black - the experience and ideas adapted to the traditional simple society are becoming less and less adapted to the modern society
the second trend is that artificial intelligence is graally replacing people's work
I will elaborate on this in the book. In short, the situation is much more serious than people think. So far, many livelihood skills, even some advanced skills, which are still easy to use, will soon be replaced by artificial intelligence. We are about to usher in an era of "changing people without changing ideas"
the third trend is that although the material life of all people is improving, the class stratification of the whole society is expanding
in recent years, studies on the gap between the rich and the poor have emphasized a point: the most important difference between the poor and the rich is not the amount of money, or even the number of opportunities, but the culture and concept. Poverty is not only an economic state, but also a mode of thinking. The difference in this mode of thinking is not only the difference in investment and financial management like "poor dad, rich dad", but also a whole set of things
for example, the degree of trust in strangers may reflect your class height. Some people have made an in-depth investigation of the social customs of Italian immigrant working-class communities in Boston area of the United States, and found that for these people, family members, relatives and acquaintances from childhood to althood are far more trustworthy than any outsiders. They think that everything outside is mysterious and even hostile. Another British study found that the working class and the poor are more likely to say things that only their relatives and friends can understand, regardless of whether outsiders can understand them - while the middle class try to explain what they are saying to everyone
compared with the love of fellow countrymen and the dialect slang among alumni, what kind of class are most of us? Is it easy for us to fall into the thinking mode controlled by the traditional acquaintance society and even the evolutionary psychology from the primitive society? Do we have the rational thinking advocated by modern society
the law of the world is not the chicken soup of the soul, so I have to say that the backward mode of thinking is difficult to change. In the book, I will introce several studies that try to change the thinking of poverty, among which there are few successful cases
Keith stanovic, a Canadian psychologist, has a book called beyond Intelligence: why smart people do stupid things, which uses a lot of research results to explain a problem: intelligence and rationality are two different things, and they are almost unrelated. Rational ability - the ability to fully understand the current situation and make the best decisions - needs to learn from others
given the scarcity of high-quality ecation resources and the great differences in family culture among different classes, who is more likely to learn rationality
considering the previous two trends, the world is becoming more and more complex and difficult to understand, and artificial intelligence is forcing us to change our minds - in such a situation, how can the gap between the rich and the poor not be widening
these three trends will pose great challenges to us. It can be said that only a few people have the wisdom of modern society, and most people's thoughts still stay in the traditional society, some even stay in the primitive society
how to meet this ideological challenge? The first step is to listen to the experts< How to listen to the opinions of science and engineering experts
Science and engineering thinking is the most important modern thinking, which stresses tradeoff, quantification and scientific methods. My last book was called "never thought: understanding the world with science and engineering thinking". But make no mistake: if you are only satisfied with your own small field, an expert in science and engineering may not be able to understand the world with science and engineering thinking< In fact, experts in science and engineering probably have a problem. If someone asks you a question about insight, if you don't use your own professional knowledge to answer it, people will say that you are not an expert in this field at all; If you use the professional knowledge to answer, you are actually a tool for reference only< How do you say that? Few practical problems in a complex world can be solved with only one aspect of knowledge. It is said that a famous scientist in the United States was invited to talk about environmental protection on a talk show once and made a big difference. Scientists engaged in environmental related research must emphasize environmental protection, but this man is more extreme. He even said that CEOs of energy giants & quot; Committed a crime against humanity
experts like this can't take you seriously. It's us who use energy, but the CEO of energy company? And a crime against humanity? Obviously, the scope of knowledge of this scientist is too narrow. He only knows a little knowledge of his own subject and thinks that what he studies is the most important. He doesn't have tradeoff's mind at all, and he doesn't know the importance of other needs in society. As the saying goes, if you are not in charge of your family, you don't know the price of firewood and rice
in my opinion, this situation is quite common. Some scientists and engineers are not very knowledgeable on public issues, and they habitually overemphasize the importance of their own profession. Climate scientists who advocate global warming claim to rece carbon emissions at all costs, as if the economic scale is not a problem at all; People engaged in aerospace believe that every dollar invested in the aerospace instry can bring a return of seven dollars; People engaged in bioenergy say that nuclear power is particularly dangerous; Physics practitioners say that the electron positron collider is the most urgent scientific research project in China in the early 1980s... Only Mr. Yang Zhenning is the most fair: as a physicist, he says that the 21st century is the century of biology
therefore, the best way to treat science and engineering experts is to take their opinions as a reference for decision-making. You can provide me with the best argument data within your professional scope, but I have to listen to other people's arguments and data on how to make a decision
a gentleman has no tools. If you are only satisfied with being a technical expert in a certain small field, I'm afraid it's not enough to make public decisions at a large scale, and it's not enough to understand life at a small scale
then, can you listen to the liberal arts experts
3. Ideas and arithmetic
Science and engineering experts at least know the limitations of their knowledge, and liberal arts experts often think that they know everything. They don't travel in the world by & quot; Rationality;, It's by & quot; Concept & quot
many humanities, including economics, political science and sociology, are still at a very early stage, which is reflected in the fact that scholars have not reached a consensus on many major issues. They are divided into many factions, often labeled with & quot; ×× Doctrine & quot; Sometimes, it's just like the sects in the martial arts world. Keynesian economics believes that consumption stimulates growth, and the government should introce economic stimulus plan; Supply side economics believes that the real heroes are entrepreneurs, so the best stimulus is tax cuts. Liberal political scholars believe that government should play an important role in social life, while conservative political scholars demand small government

on the afternoon of December 5, the people's Bank of China issued the notice on preventing bitcoin risks, in which the people's Bank of China said that bitcoin is not a currency, but a virtual commodity. In addition, financial institutions and Payment institutions are not allowed to carry out business related to bitcoin
in order to avoid over hype of virtual commodities such as bitcoin in the name of "virtual currency" and damage the public interest and the legal tender status of RMB, the notice requires financial institutions and Payment institutions to correctly use the concept of currency in their daily work, pay attention to strengthening the ecation of public currency knowledge, and correctly understand currency, treat virtual commodities and virtual currency, and promote the development of virtual currency Rational investment, reasonable control of investment risk, and maintenance of their own property safety are included in the content of financial knowledge popularization activities, so as to guide the public to establish a correct concept of money and investment. I hope I can help you
