Exchange settlement on eBay, a bitcoin platform

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
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
on February 25, 2014, the opening price of "bitcoin China" was 3562.41 yuan. By 4:40 p.m., the price had dropped to 3185 yuan, down more than 10%. According to the historical market data of the platform, on January 27, 2014, 1 bitcoin could be exchanged for 5032 yuan.

The company has entered into a partnership with coinbase, a bitcoin trading platform, to begin to accept this relatively new means of payment
although the eBay market trading platform and paypal business do not accept bitcoin payment, Braintree customers such as airbnb, a travel house rental community, and Uber, a car rental service, will be able to start accepting this virtual currency. Braintree, whose main business is to provide payment processing software to enterprises, was acquired by eBay in 2013 for about $800 million

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

Bitcoin, born on November 1, 2008, is a kind of virtual encryption digital currency in the form of P2P , which is composed of complex computer-generated code. Compared with other virtual currencies (q-coin and various game currencies are virtual currencies), the total amount of bitcoin is very limited , so it is more valuable. Moreover, based on the design of cryptography, bitcoin can only be transferred or paid by the real owner, which ensures the anonymity of currency ownership and circulation transactions

as a result, in 2014, bitcoin collapsed, and Tang Yu was flustered, but he still insisted, waiting for the price of bitcoin to pick up. However, after waiting for three years, the price of bitcoin was not as good as the price when he bought it

in the end, it was sold at the price of $750. All bitcoins were emptied. It was bought at $810 and sold at $750. Obviously, it lost money

Tang Yu now lives the same life as ordinary people, but I don't know if Tang Yu will have waves when he sees the news. Because at that time, one year after he sold bitcoin, bitcoin broke its price again, reaching nearly $20000 in history. If Tang Yu insisted on it for another year at that time, he might earn more than $2 million and now the price of bitcoin is particularly high, so I don't know whether it can accept the current reality
