When was bitcoin issued and how much did it cost
It was officially born on January 3, 2009
since 2015, the future of bitcoin has become more and more uncertain. On the one hand, bitcoin fell as much as 55.55% against RMB last year; In 2015, bitcoin fell by more than 30% against the RMB in the first half of January alone
bitcoin's "falling" reflects the "self-healing" of its value after "fanaticism" to a certain extent. According to statistics, in 2013, bitcoin rose from 1 ∶ 13.59 to 1 ∶ 731, with an annual increase of 5300%. This speculative driven inflation has affected the virtual currency property on which bitcoin relies
on the one hand, no country has defined it as a legal currency. On the other hand, in 2014, the US dollar rose significantly, and the prices of oil and bulk commodities fell correspondingly. The price trend of bitcoin is the same as that of the latter, becoming part of the asset allocation of some speculators, which highlights that its asset attribute is far greater than the monetary attribute

Security and credit risk have also become the reasons for the decline of investor confidence. Mt. GOx, once the world's largest bitcoin exchange, claimed in March last year that it had lost all its assets e to hacker attacks. Recently, it was revealed that its lost bitcoin was probably e to internal system manipulation
the regulatory environment of bitcoin is not optimistic, and Russia, Thailand and other countries have begun to implement strict control on it. In addition, the global stock market performed well last year, resulting in the diversion of bitcoin investment funds, and the crazy "mining" activities also rapidly increased the supply of bitcoin, which may lead to a trend of oversupply in the short term, leading to a sharp drop in the price of bitcoin
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.
When bitcoin first appeared in 2009, its price was less than 1 cent. One dollar could be converted into 1300 bitcoins, that is to say, seven yuan could be converted into 1300 bitcoins
on May 5, 2017, bitfinex, an overseas digital currency trading platform, quoted a price. Bitcoin once hit US $1700, about RMB 11737

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 specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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

transaction method
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. There are a lot of bitcoin addresses available
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which is used to record how much bitcoin is stored in the address. You can generate bitcoin address to store bitcoin at will. When each bitcoin address is generated, a corresponding private key of the address will be generated
this private key can prove ownership of the bitcoin at the address. The bitcoin address can be simply understood as the bank card number, and the private key of the address can be understood as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep the address and private key when using bitcoin wallet

Strictly speaking, there is no issue price for bitcoin. In 2010, a programmer bought a pizza with 10000 bitcoins, the first bitcoin deal

principle
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

1 this question is very important. The foreign exchange market is different from the stock market. It has no exchange and is a discrete global trading mode. The essence of the foreign exchange market is the inter-bank market, that is, the market in which the world's major banks trade with each other. Because the trading volume between them is very large, ordinary investors can not participate in it, so there is a platform business. These platform providers build a bridge between retail investors and the interbank market. When retail investors place an order, they are actually trading with the platform business, and the platform business uses the funds of retail investors to trade with the bank. So, it is the platform that provides you with margin service, and the margin will stay on the platform for the time being. As for the economic line you mentioned, it is actually a secondary agent. They are the agents of platform companies, so they charge more commissions
2 your reasoning is a little complicated, so you should try to use the common measurement standards of foreign exchange instry for calculation. Take Europe and the United States as an example, assuming that the exchange rate is 13000, we call one ten thousandth of the exchange rate 1 point. One hand contract is US $100000. Suppose our account is US $10000 and the margin is 1%. Now we buy a first-hand contract with a margin of $1000. At this time, the margin balance is $9000. If the exchange rate drops by one point, our balance will decrease by 10 US dollars. If the exchange rate drops 900 points, the margin balance becomes zero. These changes are reflected in your account, and they are all immediate
in fact, when the margin balance is close to zero, it is generally about 10 points, that is, about $100, the platform will force you to close the position, that is, the so-called burst position. At this point, you have about $1100 left in your account. In actual transactions, margin is used to prevent sudden major changes in the market price, generally will not be used. Therefore, there is no need to worry about platform providers
however, in order to win customers, the mainstream platforms often adopt more radical methods. When the margin balance is zero, they still keep the position of retail investors and start to lose margin. Take the above example as an example, the margin balance begins to turn negative. For every 1 point decline in the market, the margin decreases by $10. When the margin remains about 10 points, that is, about $100, the platform will forcibly close the position. At this time, the account balance is only about $100, which is a complete burst
I think the above answers your third question at the same time
4 if you buy Canada Japan, platform vendors actually need to use US dollars as a bridge to exchange for two times, so the gap between Canada and Japan is the sum of Canada and the United States and Japan, or even larger. However, as a retail investor, you don't have to think too much about it. It's all the work of the platform Shang Dynasty. You just need to know that if you add one day fluctuation point, 0,1 contract fluctuation is 1 / (0.01 * US Japan exchange rate) US dollars
however, it is worth mentioning that the euro / yen exchange rate in the cross section is quite special, because the trading volume is very large, it is often direct trading, and it does not need to be mediated by the US dollar, so the currency spread is relatively small on many platforms
I hope I can help you.
