Bitcoin worth 2 trillion
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

monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. 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
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
If you use three words to describe the latest bitcoin, it can only be three words & quot; It's going crazy;. On February 19, the price of bitcoin reached a high of US $56000, with a total market value of US $1 trillion{ RRRRR}
coupled with the global popularity and high liquidity of bitcoin, long-term holders believe that bitcoin is an ideal medium for long-term wealth storage and will appreciate over time
how does bitcoin work? In the bitcoin system, the way money drives is not the digital transfer of cash that most people imagine. When Alice remits money to Bob, Alice's process is like recording on the account book that everyone sees that she transferred $1 to Bob. If Carol wants to charge Bob a dollar, she can see from the same ledger that Bob does have a dollar
If you really don't know about bitcoin, you will know that the earliest holder of bitcoin has made money. Do you think that bitcoin is rising and he has to sell when he makes money? Will he keep holding it? Are ordinary people, in the face of such a big temptation, can not hold on
later, people were cut like leeks, wave after wave. At least among the people I know and the stories I heard, no one made money because of bitcoin
summary:
what is bitcoin? I don't know. It's like virtual currency. It can't be used for payment or transfer. There's also a so-called dark net
the rise and fall is just like gambling. At the beginning, gold and silver were bought in the same way. Gambling is risky and investment should be cautious. people want to eat all the time when they get the sweets. Do you know what is to stop when it's good? Don't be greedy, you are just a leek in the eyes of bitcoin, not a bundle, understand
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.
in the first four years, 50 pieces were g out every ten minutes: 50 * 6 * 24 * (365 * 4 + 1) = 10519200 pieces
in the second four years, 25 pieces were g out every ten minutes: 25 * 6 * 24 * (365 * 4 + 1) = 5259600 pieces
according to the sum formula of infinite equal ratio sequence, the final total amount is infinitely close to 21038400 pieces (10519200 * 2)
as long as the mining rules are not changed, the number of bitcoins will never exceed 21038400
I hope it will help you
The total market value of bitcoin has exceeded US $1 trillion. What is the reason that makes it so powerful? Let's take a look at bitcoin. 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 a specific monetary institution to issue. It is generated by a large number of calculations based on a specific algorithm
from the performance of bitcoin at this stage, bitcoin has low liquidity level and high liquidity risk, so it can not effectively perform the three basic functions of currency: transaction medium, pricing unit and value storage, and can not become a real currency< because it is not a currency in circulation, it has no legal status, so it is not recommended to invest in bitcoin because the risk is too high so far, countries have not recognized the value of bitcoin itself, so the risk of bitcoin is relatively high. But there are also many people who can't resist the temptation of money, so they choose to start bitcoin. But in the end, they have suffered a lot, and some people have paid for their lives
no one can really master bitcoin. If you are interested, you can learn more about it. Many people speculate that bitcoin will continue to rise. If you have spare money, you can invest some first, but you must keep a rational attitude
