Types of bitcoin users
1. Legal currency transaction: that is to buy, sell or trade digital assets through legal currency. For example: bitcoin now quote 6 in case, then whether it is credit card or Alipay WeChat, anyway, buying money directly is the legal tender transaction.
2. Currency currency transaction: mainly for transactions between virtual currency and virtual currency, one of which is used as the pricing unit to purchase other currencies. Its trading rules are also based on price priority and time priority
3. Leverage Trading: it is to invest several times of the original amount with small amount of funds. In order to obtain the relative investment object volatility multiple yield, or loss. As the increase or decrease of margin does not move in proportion to the fluctuation of underlying assets, the risk is very high
4. Contract trading: contract trading is the general term for the futures contract trading of the 796 exchange in comparison with the special currency. In June 2013, 796 exchange took the lead in developing bitcoin weekly delivery standard Futures - t + 0 two-way trading virtual commodity barter contract (contract trading) in bitcoin instry

Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of 
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
The concept of 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 universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
Let's start with a simple conclusion: a year ago, the data showed that there were about 500000 BTC
two American brothers, Cameron winkleworth and Taylor winkleworth, claiming that they owned 1% of bitcoin [1] 1% of the world's bitcoin? At present, the total amount of bitcoin in the world is about 12 million, that is to say, the two brothers hold about 120000 bitcoins< maybe you don't think it's worth much, but note that the starting price of bitcoin for these two people is less than $10 / bitcoin
Please note that entities are used instead of people. In the analysis method of this paper, bitcoin wallets that may belong to the same owner are divided into the same entity, which may be not only a person, but also a trading organization like Mt. GOx in addition, through the analysis of the most active entity table given in this paper, the income of the people with the most income (excluding expenses) is less than 700000 BTC. In other words, the person with the most bitcoin will hold no more than 700000 bitcoins. How many people in the world own bitcoins? The paper concludes that as of May 13, 2012, 1.85 million entities hold bitcoin. If we assume that bitcoin users have grown linearly since the advent of bitcoin (January 2009), the current number should be 2.5 million. Because the number of entities is counted on paper, the actual number of bitcoin holders should be a little less than this number, but not much smaller, because after all, there are not many large trading platforms
In addition to the above two problems, [3] also gives many interesting conclusions, such as: < UL >about 55% of bitcoin can be saved without money
in places like GOx mountain, almost all deals are small ones
before May 2012, almost all large single transactions (& gt; 50000 BTC) are subsequent transactions of 90000 BTC on November 8, 2011. There are very strange patterns in this long list of transactions. For example, an entity divides 90000 BTCs into different sizes, sends them back to itself three times, and then sells them on Mt. GOx. 90000 BTCs sold are sent back to the entity through 90 different bitcoin addresses, with 1000 bitcoins per address. These operations indicate that the entity appears to be trying to hide the relationship between these transactions
bitcoin does not have a centralized issuer. It is generated by the calculation of network nodes. It can be bought and sold on any computer connected to the Internet, and has a strong scarcity
Decentralization: bitcoin is the first distributed virtual currency. The whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global 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
exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
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
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform mining: users can explore the computing power of different hardware on many platforms

e to its broad prospects and huge reverie space, the price of bitcoin has continued to rise since its birth in 2009. In 2011, the price of bitcoin reached $1, and in 2013, the highest price reached $1200, which exceeded the price of one ounce of gold. Bitcoin has the reputation of "digital gold" (the current price is about $450)
bitcoin began in 2008 with the paper bitcoin: a peer-to-peer e-cash system (Chinese version) by the mysterious figure Satoshi Nakamoto. In the six years after its birth, bitcoin, as an unprecedented new currency, has experienced numerous market tests and technical attacks and has always stood firm. Now bitcoin has grown into a currency system with millions of users and tens of thousands of businesses accepting payments around the world, with a market value of up to 10 billion US dollars.
Nakamoto's mining is unreliable
On October 31, 2008, a person named Nakamoto published a research report called bitcoin: a peer-to-peer cash payment system on a secret cryptography discussion group, which elaborated the new idea of e-moneysoon after, he developed an operating system for bitcoin issuing, trading and account management on the platform of P2P (peer-to-peer or person to person) peer-to-peer network and distributed database, combining the working mode of open source software and block cipher in cryptography
the system enables all nodes throughout the peer-to-peer network to reach network agreements according to their seed files, so as to ensure fairness, security and reliability in currency issuance, management and circulation
after the advent of bitcoin, it quickly attracted the following and attention of geeks. However, what is puzzling is that after leaving bitcoin in cyberspace, Nakamoto Tsung has not been as frequently active in the bitcoin community as before, but graally faded out of the public's sight
in the spring of 2011, after leaving behind the sentence "I started to do something else", Nakamoto completely evaporated from the Internet space. No one can know his real identity, only that this mysterious figure left 2 million bitcoins for himself in the earliest block he owned, and these bitcoins have not been passive yet
people want to see the true face of Nakamoto, and even use the powerful human flesh search tool to search, which is still fruitless, Even the two Google engineers who later took charge of repairing the bitcoin project claimed that they had never found and met Nakamoto at the scene
extended data mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times
miners provide algorithms for bitcoin network in exchange for the opportunity of bitcoin reward. The miners verify each new transaction and record it in the general ledger
every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn
we call the transactions included in the block and added to the blockchain "confirmed" transactions. Only after the transaction is "confirmed" can the new owner spend the bitcoin he gets in the transaction
for users, BYD Han may not only be a work that starts with facial value, but also has a GT style, which shows that it has unique performance. Different from those friends who are reformed from fuel vehicles, BYD Han directly cancelled the design of the air intake grille and replaced it with a chrome plated decoration that runs through the front face. In order to further enhance the sense of decoration, there is led light belt under BYD Han chrome plating, which will be lit together with the "Han" logo when the vehicle starts up. If you add a circle of running lamps, the picture should not be too beautiful
it is said that the drag coefficient is an important measure to judge whether a car is good or bad. The lower the value, the better. Through the precise design and the way to make the ventilation slot, diversion slot, front cover and wiper slightly rise, BYD Han reces the drag coefficient to 0.233, which is lower than Ferrari 458, BMW I8 and even Tesla Model S. the benefits can be reflected in the chat
for a car with a body length of nearly five meters, it is very difficult to design a good-looking car. Especially in the interior, if you want to show a high-level texture, you can't just go to the auto parts city. It is said that in order to solve this problem, BYD invited a former Mercedes Benz designer to build the whole process. BYD Han is based on black and red as a whole. The use of color is very radical and bold. The color matching steering wheel, all red seats, and the air conditioning port of the Dragon shutter are also full of personality. Of course, BYD's signature rotating central control screen is indispensable. The operating system is equipped with Huawei 5g technology. The light of domestic procts still needs some feelings
as the heart of new energy vehicles, battery has always been the core problem that plagues the scale of electric vehicle market. At the end of last year, Wang Chuanfu, chairman of BYD, disclosed on various occasions that they had developed a super battery. Until the end of March this year, BYD took off the mystery of super battery blade battery. The battery has better security. How safe is it? You can check our previous article "Ningde times successfully attracted my attention in digging a hole"
at present, most of the electric vehicles in the market are lithium-ion batteries with unstable chemical properties. In the needle penetration test (the instry recognized means to check the safety of the battery cell, that is, to use a steel needle through the battery to observe the battery reaction), the ternary lithium battery reaction is very excited and deflagration occurs, while the blade battery performance is bright, no open fire, smoke-free, surface temperature of 30 ℃ ~ 60 ℃. This performance is unprecedented. At the same time, compared with the traditional battery pack, the energy volume density of the battery is increased by 50%, thus increasing the total capacity of the battery. However, this is not its main improvement point. Its safety and stability has changed the development of the whole new energy vehicle instry, which is of milestone significance. After all, safety is the most important thing of the car
now, BYD loads the battery on the Han EV, the flagship car of the dynasty series. The pre-sale price is between 24W and 28w. Speaking of Han, I have to mention Tesla China model 3. Han EV loaded with blade battery, 100 km acceleration is 3.9 seconds, 100 km braking distance is 32.8 meters, it is said that this data is the shortest braking distance of new energy vehicles in the world. The maximum range is 550km and 605km, with four-wheel drive high-performance flagship, equipped with front and rear al motors, the comprehensive maximum power is 363kw, and the maximum torque is 680n. If we only look at the book parameters, it seems that BYD Han's other data are better than model 3 except for mileage. Especially in the fast charging mode, the official announced that BYD Han can charge for 10 minutes and drive 100km, which is amazing
so far, BYD Dynasty series has proced four of them, namely, Qin, Tang, song and Yuan Dynasties. It is a c-position pioneer, carrying Huawei 5g technology and blade batteries that look more secure and stable. The so-called "those who commit crimes will be punished far away". It may be the best choice other than Tesla. It's too early to say who will replace whom
