unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
on December 17, 2017, bitcoin reached an all-time high of $19850. On July 27, 2020, bitcoin broke through the $10000 mark again [2]<

from the transaction of things In 2008, the global financial crisis broke out. On November 1 of the same year, a person who called himself Satoshi Nakamoto published the white paper bitcoin: a peer-to-peer e-cash system [6] on the P2P foundation website, stating his new idea of e-money bitcoin came out. On January 3, 2009, bitcoin Genesis block was born
there are three bitcoins in total
compared with legal tender, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or receive bitcoin, And in the transaction process, foreigners can not identify the user's identity information. On January 5, 2009, bitcoin, which is not controlled by the central bank and any financial institutions, was born. Bitcoin is a kind of digital currency, which is composed of a series of complex codes generated by computer. The new bitcoin is made by preset program
whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses always focused on whether bitcoin was a scam. Now the analysis is always focused on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin[ 7]
many bitcoin players are attracted by the fact that bitcoin can not be added at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin
Keynesian economists believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progress
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer[ 6]
in 2009, when bitcoin was born, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25. When the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million[ 3]
bitcoin is a virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items

overseas mining rise: batch construction of us factories, On November 1, 2008, a self styled Satoshi Nakamoto published a bitcoin white paper, bitcoin: a peer-to-peer electronic cash system, on the P2P foundation website, stating his new idea of electronic money bitcoin came out
Wang yuexinyi, Professor of mathematics at Kyoto University, was born on January 3, 2009. Bitcoin uses distributed ledger to get rid of the constraints of third-party institutions, which Nakamoto calls "blockchain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money. Business is also extended on this network. Computers running this software are scrambling to solve the problem of irreversible code, which contains several business data. The first miner to deal with the problem will get a 50 bitcoin reward, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
according to foreign media reports, computer scientist Ted Nelson released a video on the Internet on Sunday, saying that he has determined that the founder of bitcoin is Shinichi Mochizuki, a professor of mathematics at Kyoto University. The founders of bitcoin have always used
the bitcoin market is an extremely crazy market. Some people have become billionaires overnight, while others have been cut leeks. The ups and downs, joys and sorrows of the world are incisively and vividly interpreted anyone who knows about the bitcoin market should know that before, the value of bitcoin was only 1000 yuan, but it rose to 17000 yuan in 2017. With such an appreciation rate, the profits matched with it are also amazing. Bitcoin appeared in 2009. At that time, the value of bitcoin was only US $0.1. Looking at the price in 2017, there is a big difference between the two. If someone had a lot of bitcoin when it first came out, he would be one of the richest now
When the engineer became a billionaire, he began to travel around the world. In fact, he has long had the idea of traveling around the world, but e to economic reasons, it has not been realized. Now, the engineer can live freely and realize his dream of traveling around the world. In an interview with reporters, the engineer also said, although his original job is very good and can provide him with stable income, he has always dreamed of the global world and visiting friends from various countries. Now, he is living the life he wants, and by selling bitcoin, he has got hundreds of millions of assets, which is enough for him to spend his whole lifeWhat's the status quo of those who bought 20000 bitcoins at the beginning
I feel that people are still very curious under this situation. In fact, the price of bitcoin is already very high. Under this high price, many people may think that if they invest in bitcoin, they may make a lot of money. Therefore, many people are very eager and curious about it, What kind of value can it proce
so I think this kind of situation has to give us practical exploration and a lot of other communication, so I feel that this person's situation may be much better than what we think, because they may have made a relatively high profit by investing in bitcoin, and if this kind of profit continues, It is possible to generate more income space, and this space will continue. The above is my answer to this question. I hope my answer can be helpful to you. If you like, you can pay attention to it in the relevant comments area. I will actively interact and discuss with you
In my opinion, from the point of view of the couple, they have lost confidence in their current life because of the failure of investment and the collapse of their property. When they are frustrated, they kill their children and prepare to commit suicide. They don't want their children to suffer in the world alone and helpless. I think this is understandable
however, since ancient times, the law has no obligation, so the law must be absolutely fair and just to ensure its authority. For whatever reason, no one can unlawfully deprive others of their lives
{rrrrrrr}
the author's point of view:
in fact, Zheng owes a lot of debt now, his wife and children have died, and life has no meaning for him. In my opinion, the only thing he wants now is the court to sentence him to death
However, according to his situation, the court may not be able to sentence him to death. It's hard to think about the feeling that you can't dieBitcoin is basically a well-known term for many netizens, and people who know about it also know that bitcoin is not cheap in today's world. The price of a piece of bitcoin is frighteningly high. Although it is also called gold coin, it is not forgotten by it and the real currency circulating in the world today, It is not a real currency circulating offline in today's society, but a virtual currency circulating through online circulation, which is usually used in various network transactions, and can also protect the information of both parties. Now its value is also rising step by step. It was first proposed in 2008, and then formally invented in 2009 for circulation. When it first came out, its value was very low. The price of a coin was only US $0.1, which was pitifully low. However, after only a few years, the value of bitcoin rose sharply
it is reported that this lucky man is an engineer in the network engineering instry. Because bitcoin is a virtual currency emerging on the Internet, and it is also a network engineer, it has a natural contact advantage compared with people in other fields and instries. In the first year after the advent of bitcoin, he learned about bitcoin from a friend, Thanks to its keen mind, it spent 3000 US dollars, about 20000 yuan, and hoarded 20000 bitcoins. After that, as we all know, the value of bitcoin increased greatly. When it reached 350 US dollars in 2013, it sold 2000 of them. After that, it continued to sell some of them in the process of rising prices, Now he has become a billionaire, quit his job and travel around the world to enjoy his life. Now he has 1000 bitcoins. According to him, he plans to sell them all at a unit price of $150000 to make the last profit
