Tiger sniffing digital currency
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%.

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
freetrade
tiger sniff website, which is the first digital currency contract for differences transaction launched. At present, there are five procts BTC / eth / LTC / etc / EOS that can be traded.
the one that meets the above conditions is fraud. You can report to the public security organ
the report number is 110.
1. Build a blockchain ecosystem.
Why do start-ups join in blockchain public chain projects? Because it's a great opportunity. Any enterprise has the opportunity to create an ecosystem that subverts the existing pattern with its own ideas and operations. In this system, the currency designated by the ecosystem owner will circulate
2. Providing services for enterprises
providing services for enterprises is the main profit model of blockchain projects at the present stage, and cloud storage security skeptics are likely to turn to traceable and tamper proof blockchain service providers to seek maximum data security
3. Smart contract participates in profit making
smart contract is like a contract that can be executed automatically. The validity of the contract is judged and enforced by machine instead of human. Its essence is still a piece of code, but the traceability and non tampering characteristics of blockchain can ensure that this piece of code runs automatically under the non trust mechanism. Blockchain is the precondition of smart contract operation
4. Special service driven system operation
many enterprises have their own exclusive fields in building blockchain communities. Take the neurogenomics project led by geneticist church as an example. After enjoying the gene sequencing service provided by neurola, consumers can not pay in the form of legal money, but have to exchange legal money into the token issued by neurola< The original purpose of project 1CO is to crowdfunding in the market through pre-sale service. In 2013, the early 1CO company appeared in the financial field, and then quickly detonated the entire digital money market, resulting in the rise of speculation
6. The foundation of sharing economy is to realize the maximum utilization of resources by monitoring the available resources and corresponding demands in real time and making adjustments. For unicorns like airbnb, they have a mature management mode and stable cash flow. They try blockchain because blockchain technology can bring more transparent, more efficient and fairer systems.
bitcoin appeared in 2008. It is a decentralized, anonymous currency that can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world
(2) the origin of bitcoin
in 2008, someone published a paper under the pseudonym "Satoshi Nakamoto", which described the use of bitcoin. One year later, the first transaction of bitcoin was completed
(Hu olfactory note: according to this article of Forbes Chinese website, the mysterious figure with Japanese name has disappeared on the Internet. No one knows whether he is really Japanese or a huge institution Wired speculates from his wording that he may have been born in the United States, or even the code name of Google or a mysterious group of the U.S. National Security Agency.)
(3) where does bitcoin come fromusers can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to algorithms. When users "mine" bitcoin, they need to search for 64 bit numbers by computer, 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, they will get 25 bitcoins
e to the decentralized programming adopted in the bitcoin system, only 25 bitcoins can be obtained every 10 minutes at present, and 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
(4) how much is bitcoin worthwhen it first appeared, bitcoin was almost worthless. One dollar could buy 1309.03 bitcoins on average, but now the value of one bitcoin is equivalent to 135.3 dollars. Interested friends can visit preev website to learn about the real-time quotation of bitcoin
(5) can bitcoin be exchanged for cash The answer is yes. You only need to contact bitcoin trading institutions to complete the exchange. Mt. GOx is the most popular bitcoin trading platform, but now the platform only accepts new members through one application. In addition, there are several large exchanges that can exchange and trade bitcoin(6) why should bitcoin be anonymous? How to realize anonymity
the reason why bitcoin is anonymous is that they are built on a decentralized system. Bitcoin is completely independent, and the outside world cannot shut it down through some kind of core infrastructure
"anonymity" is very useful for those who don't want to associate their name with the goods or services they purchase. What outsiders see is nothing more than the address of your bitcoin wallet and a string of random words and numbers. Besides, there is no information that can identify themselves. At the same time, for relatively paranoid users, you can also create multiple new wallets for free
(7) what can bitcoin do
previously, it was reported that criminals used anonymous bitcoin to buy drugs, guns and other illegal goods, but in fact, many legal businesses also accept bitcoin transactions. For example, Howard Johnson is willing to accept bitcoin payment, and bitelectronics is a consumer electronics store that only accepts bitcoin
(8) why should we pay attention to bitcoin
bitcoin represents a completely anonymous and cost-free transaction mode. Bitcoin does not belong to any country and is not subject to geographical restrictions. It is a currency that users can freely convert anytime and anywhere. There is no reason why we should not pay attention to this new and promising currency
(9) is bitcoin legal
bitcoin is not real money, it does not represent a certain value like paper money and coins. At present, the U.S. government is not worried about the impact bitcoin may have on the financial market, because it can manage and control bitcoin only by enacting corresponding laws. Compared with the "free dollar" that once appeared, the latter is a kind of currency that can replace the real thing between 1998 and 2009, and its creator, Bernard von nothaus, was also convicted in 2011 for making, possessing and selling the money himself
