After bitcoin 95
bitcoin mining machine is the computer used to earn bitcoin
mining software is the algorithm of bitcoin
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
extended data:
bitcoin has the following six characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Worldwide circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform Mining: users can explore the computing power of different hardware on many platforms

The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 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

Whether in the past or in the future, we have always advocated that indivial interests should be in line with collective interests. When facing social and economic interests, we should first consider social value. When dealing with virtual currency shuttling through financial transactions, how should we choose its social and economic value
there are thousands of virtual currencies in circulation in the market, and not every currency will follow the principle of social value first. From December 17 to January 18, many virtual currencies scrambled the trading market by virtue of ICO chaos, which not only made many investors lose money, but also lost the hope of increasing the value of virtual currency, This kind of virtual currency not only has no social value, but also can never realize its own economic value
As the first virtual currency to appear in the public's eyes, bitcoin is a financial proct with both social and economic values. It not only grows graally in the process of development, from less than $1 to $10000 + today, but also drives the development of the whole instry. Bitcoin is the leader and protector of the emerging instry, Its contribution is multifaceted and its advantages are incomparable As a new emerging virtual currency, mycoin may not seem warm now, but the soup made by slow fire is often different. I hope mycoin will move closer and closer to bitcoin and compete with it in the near futurethere are two ways to trade bitcoin, one is spot trading, also known as currency trading, which requires the purchase of usdt (omnilayer protocol based digital assets released on bitcoin blockchain), and then the purchase of spot, and the other is futures trading. the futures trading is divided into delivery contract trading, which is generally a weekly contract, Next week contracts, quarterly contracts and perpetual contracts
6, when I successfully transfer my bitcoin recharge to the trading platform, I can sell my bitcoin on the trading platform. On the trading platform, click the "sell bitcoin" option under the trading column
7. Then select the type of order to sell, the quantity of bitcoin to sell, and click the "next order" button to continue
Similarly, the record of selling bitcoin can also be seen in the transaction query under the transaction column9, when the transaction is successful, you can withdraw RMB to your bank card. Under account management on the left side of the page, click "RMB withdrawal", and then fill in according to the required format in the right pane. Finally, click the "withdraw" button
The concept of 21 million
bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million

generation 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 infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is 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 distribute a private key and a public key. You need to back up your 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
money is now a tool that can not be acquired by human society. Its existence greatly facilitates the transactions in our daily life. But now it is a mobile payment era. There is very little physical money. Most of them are Alipay or WeChat. But does the big family know that there is a currency called bitcoin? It's a kind of virtual currency. Now it's very valuable. Once a person bought 100000 bitcoins. What's the matter now
After that, Li Xiaolai quit his job as an English teacher and started an investment company with a value of 67 billion yuan. He also opened many courses on Internet investment for you to learn. Many people call him "the richest man in bitcoin in China". However, he may be one of the people with the most bitcoin in the world, It can only be said that Li Xiaolai's eyes are really poisonous.

generally speaking, the value of money depends on its activity: the central bank prints a lot of money and puts it into the economy with high-speed monetary activity. Therefore, we find that if the value of money decreases, we will be more inclined to sell in the future, resulting in a further decline in the quoted price. This cycle will lead to a runaway effect
for bitcoin, there is no high speed activity of bitcoin. Only the speculative bubble burst, and the quotations get closer to the mall balance point. This leads to a humorous question: where is the balance? First of all, let's make some assumptions. If in the future, no one in the world will hoard bitcoin at all: no one believes that bitcoin will rise, but will only fall in the future. Therefore, in the near future, we will only purchase procts by purchasing just enough bitcoin. In this way, the quotation of bitcoin depends entirely on the demand (the amount of bitcoin that people spend on purchasing procts and services) and the supply (the amount of bitcoin that exists). We are going to test to set up a lower bound: there will be some conjecture data in it, so we are going to choose the more extreme (disappointed) data. Data results are relatively small, and are affected by many factors, but data results can let us roughly know the magnitude of the answer to the question. In addition, we have the same assumption that everyone has lost interest in all counterfeit coins: we only pay attention to the bitcoin quotation supported by the bitcoin demand brought by real procts and services, that is to say, we do not use the statistical data of business channels to count the demand
let's get started. It is an excellent representative of the total demand of bitcoin for procts and services. It is the total activity of coinbase and bitpay, the two largest bitcoin payment processors in the bitcoin instry. Of course, bitcoin for procts and services also occurs in other places (this does not include the bitcoin compensation paid by some companies). The total bitcoin traffic of these two payment processors can exceed 50% of the bitcoin demand in all bitcoin businesses: the service of all large-scale commercial bitcoin transactions is coinbase or bitpay
surprisingly, neither coinbase nor bitpay clearly revealed their detailed business data. Fortunately, we can make a reasonable and accurate guess about the implied meaning of some articles announced by them. For example, we know that bitpay's business volume in 2013 was $100 million, and we also know that its business volume in 2012 was $3 million. Bitpay was founded in 2011, so we can reasonably guess that the total business volume of bitpay at the end of 2013 will be at least $94 million. Coinbase didn't disclose similar data, but both sides made clear the detailed number of cooperative businesses: bitpay is "more than 30000 businesses", coinbase is "31000 businesses". If we assume that the average bitcoin business volume of each of the two payment processors is similar, then the revenue of coinbase and bitpay are very similar. Let's calculate according to this. They are all US $100 million per year, or the remaining 50% of bitcoin needs that do not flow through coinbase and bitpay will bring us $300 million per year. In fact, since it is almost certain that there will be a continuous increase in 2014, these figures are likely to be higher. Since it is difficult to evaluate the detailed increase, let's leave it alone and simply assume that it will be $300 million in 2014
according to the current quotation of bitcoin (US $474), the total value of bitcoin mall is about US $6 billion, so US $300 million only accounts for 5%. That is to say, 95% of the total demand for bitcoin is speculative. Therefore, our estimation of the lower bound of bitcoin price is 23 US dollars. At this moment, the natural market's strength will prevent the price from further falling
let's analyze the above achievements reasonably. Our approximate data comes from bitpay and coinbase's bitcoin traffic (2013), and the bitcoin traffic of the three major business channels is accounted for by the partners working in coindesk. The channel traffic of bitcoin business is mainly speculative business (and counterfeit money business), which can hardly represent the business needs of bitcoin brought by any procts and services. At the same time, the three major business channels in the world (Mt. GOx, bitstamp, btc-e) account for 93% of the total amount of bitcoin shopping malls, and 7% are not included. We think that it is appropriate for the real commercial bitcoin demand to account for 5%
but will bitcoin really fall to $23? Very likely not. Let's assume that bitpay and coinbase did not increase in 2014, which is 100% wrong. Overstock, a US online retailer, Dell, a global PC retailer, and Xindan, a US e-commerce channel, announced in 2014 that they had accepted bitcoin payment, so the real amount could be several times higher. In addition, no one can store bitcoin and counterfeit coins at all. Therefore, this achievement is likely to be far lower than the low bound of the actual quotation, but it also gives us a general idea of where the equilibrium point of the market can exist, and the current bitcoin quotation is actually unsustainable.
