How many accounts does bitcoin have per person
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
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
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

it should be said that the rapid rise of bitcoin is closely related to the fact that more and more large and small businesses began to accept bitcoin as a payment method in 2014.
when you play BBT, please consider the following questions carefully:
1] does anyone know the founder and operation team of BBT
2] does the BBT system have any physical or organizational support or endorsement
3] is BBT a kind of open source digital currency? Is the source code public
4] is BBT a spontaneous market like bitcoin, and is it decentralized
5] why isn't BBT the mainstream Shanzhai coin trading platform at home and abroad?
