They are:

bitcoin

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin cash

bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

extended data:

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

2. 1. According to the bitcoin mining mechanism, it will eventually be infinitely close to 21 million, but it will never be reached
it can be roughly understood as the relationship between 0.9 (9 infinite cycle) and 1
2. Even if there is only one bitcoin left in the world, it means that there are 1000 0.1 bitcoins and 100000 0.01 bitcoins in the world
let's assume that the function of bitcoin is equivalent to that of gold as a currency anchor (in fact, it also has this function). You will understand that there are 21 million bitcoins in the world and only 0.1 bitcoins in the world are the same. The currency itself or bitcoin

for example, if the number of bitcoin in the world is reced to one tenth, the market price of bitcoin should be 400000 yuan (to understand this needs a certain economic basis)

so whether bitcoin is in circulation or not has nothing to do with the quantity.

3. It is recommended not to participate in investment,

this kind of virtual currency is not a digital currency recognized by the central bank,

it is not protected by law,

the corresponding platform may collapse or run away at any time.

It's not against the law to do bitcoin business, but don't use bitcoin to do illegal things

in China, the regulations on the administration of RMB prohibit the proction and sale of token tickets. Because there is no clear judicial interpretation of the definition of token ticket, if bitcoin is included in the "token ticket", the legal prospect of bitcoin in China will face uncertainty

the notice of the Ministry of culture and the Ministry of Commerce on strengthening the management of virtual currency of online games (Wen Shi Fa [2009] No. 20) on June 4, 2009 stated that the application scope of virtual currency of online games was defined for the first time, and the distinction between the current virtual currency of online games and the virtual props in the game was made; At the same time, the notice said that the "notice" stipulates that enterprises engaged in related services must be approved before they can operate

in China, some Taobao stores also began to accept the use of bitcoin, and the number of businesses will graally increase

in October 2013, the first bitcoin quarterly, one bit, was released

on October 15, 2013, the network accelerator service of the network announced its support for bitcoin

on October 26, 2013, btcmini reported that GBL was hacked

on October 31, 2013, Lei Teng, a famous Internet lawyer, proposed the event of "filing a case to investigate the closure of GBL bitcoin trading platform as soon as possible", analyzed the "value function" and "use function" of bitcoin, and bitcoin should be governed by relevant laws

on December 5, 2013, notice of the Ministry of instry and information technology of the people's Bank of China, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing bitcoin risk: bitcoin is a specific virtual commodity

as a commodity trading behavior on the Internet, ordinary people have the freedom to participate in bitcoin trading at their own risk

on September 4, 2017, announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risk of token issuance financing: it is prohibited to engage in token issuance financing activities (ICO)

the trading platform shall not engage in the exchange business between legal tender and token, or virtual currency, or buy or sell token or virtual currency as a central counter party, or provide pricing, information intermediary and other services for token or virtual currency

on November 2, 2018, the people's Bank of China released the 12th topic of China financial stability report 2018, which talked about "encrypted assets"

extended information:

currency transaction

purchase method

< P > users 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, by repeatedly solving mysteries, compete with other gold miners to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, it will get 25 bitcoins

e to the decentralized programming of bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the upper limit 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

5. One of the controversial attributes of bitcoin is its fixed supply. At present, 25 new bitcoins are proced every 10 minutes, and the number is halved every four years. Overall, there won't be more than 21 million bitcoins & gt;. On the other hand, each bitcoin can be divided into 100 million shares (each is called 1 "cong"), if one cent is enough to buy a car, it will be troublesome to trade in US dollars, but even if bitcoin rises to the level of US dollars assumed above & gt; We will not encounter such problems. Therefore, in short, the total number of monetary units that will always exist is 2100 billion, that is 2100 trillion, or 250.899. In the square of choosing this value & gt; In fact, Nakamoto is much luckier or smarter than most people realize. First of all, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, & gt; The value will return to zero like a odometer
secondly, however, there is a smaller threshold for the total number of "smart": the largest possible integer that can be represented in floating-point format. Integers are not the only numbers that computers can store; To deal with decimals, computers & gt; Use a format for floating point representation. Floating point notation is essentially a binary version of scientific notation. For example, here is a value you will encounter when you study physics:
mass of the earth: 5.972 1024 kg
mass of the sun: 1.989 1030 kg
speed of light: 2.998 108 M / s
light year: 9.460 1015 m
mass of proton: 1.672 10-27 kg
Planck length: 1.616 10-35 m
we can notice that, How does scientific notation allow you to represent all of these values with reasonable accuracy, even though they vary greatly in size. Floating point notation is essentially a binary scientific notation; When you store numbers & gt; When the word is 9.625, what your computer stores is "1.001101
* 1011" (in other words, it stores 0100000000100011
& gt; This is the same thing with high-precision sequence form). In this high-precision form, the coefficient (that is, the part that is not the exponent) has 52 bits. This means high precision (more refined & gt; Double precision floating point number is enough to store up to 253 numbers, but it can't be any higher. If it exceeds 253, you have to start cutting off the numbers at the end. Bitcoin's 250.9, the total number of "smart" in the form of index, is just & gt; OK, below this maximum
if we have integers, why should we care about floating-point values? Because more high-level programming languages (such as JavaScript) do not open low-level "floating point" and "integer representation", but only provide "number" representation for programmers; Concepts
– of course, in floating-point form. If Nakamoto chose 210 million instead of 21 million at that time, bitcoin programming in many languages would be much more troublesome than it is now
note that Stefan Thomas unfortunately didn't notice this in time when he wrote bitcoinjs, so that the library used a special "big number big
number" object instead of an ordinary number to store the tutorial output value; My own bifurcated bitcoin JS (along with other improvements) uses ordinary numbers.

6. For example, you are the head of a village. In your village, only the money printed by your family can buy things and circulate. You can print as much as you want. Suddenly, the second eldest brother next door got angry and said that your family was printing money in such a disorderly way, which made things more and more expensive. He managed to earn more and more money in the village. He found that he was saving more and more money, but he just saved a lot of figures, because things were more and more expensive, So your second eldest brother issued a kind of digital encryption, decentralized digital currency. This kind of currency can't be added. There is a limited number of currencies. Every village has one more, and it won't be exploited by your family. At this time, are you out of stock?

7. There are not so many bitcoins in the world for you.

8. 21 million? There is no upper limit. Who can play with you? How can the price be speculated.
