Why should bitcoin be measured in US dollars
Because 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
many websites for technology players have begun to accept bitcoin transactions. For example, websites like hotcoin, coin an and okex, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin. There are specialized bitcoin third party payment companies abroad, similar to the domestic Alipay, which can provide API interface services. p>
you can use money to buy bitcoin, or you can be a miner to "mine" them, and use computers to search for 64 bit numbers. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network. If the computer can successfully create a set of numbers, it will get 12.5 bitcoins
bitcoin is decentralized. It needs to create a fixed number of bitcoins in each unit of computing time. It can get 12.5 bitcoins every 10 minutes. By 2140, there will be 21 million bitcoins in circulation. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging
extended data:
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
Many people must have seen the news of bitcoin soaring through various channels, so why can bitcoin have risen to the price of US $28000 in a short time? Many netizens also talked about this. After all, as an investment channel without any credit endorsement, The price of bitcoin deviates completely from the current investment method. I've read some reports about this, and I'd like to share with you some of my thoughts behind the sharp rise of the bitcoin{ RRR}
is bitcoin worth investing
in fact, I have given other answers to this question. You can have a look. I do not recommend you to complain about any bitcoin answer, because bitcoin has collapsed. At that time, bitcoin was worthless. Everyone wanted to sell their bitcoin, but in the end, its price picked up again. In this case, who was the last winner? I hope you can consider it clearly
Many people think that the reason why bitcoin is valuable is because it is "rare", and if bitcoin is no longer "rare", then it will not have value
this is a misunderstanding. Let's consider a question: what is the essence of all "currencies"
the answer is trust. The biggest reason for the value of the dollar is because of the credibility established for the dollar under the Bretton Woods Agreement, rather than the so-called equivalent exchange with gold (although others say so). The main reason why RMB is valuable is because of the trust system of RMB in China and neighboring countries, rather than the exchange with us dollar reserves (see offshore RMB). This can explain why the currencies of some countries (such as the ruble of Russia, as well as the Zimbabwean currency as you all know) have been greatly devalued, because the government and the current world situation have led to a trust system that does not support the existence of this currency. The so-called economic sanctions and currency speculation are very superficial and superficial reasons
the essence of money is trust
What about bitcoin
bitcoin has no centralized Trust Measurement institution. The value of bitcoin, namely its "credit system", comes from distrust of centralized units. Every country finds that seigniorage is too easy to collect, which leads to the increasingly poor trust between countries. Even the people of all countries do not trust the national currency
and trust, like quality, is conserved. Trust in centralized money decreases, while trust in decentralized money increases naturally
this is the essential reason why the value of bitcoin continues to rise. Therefore, for digital currencies such as bitcoin, there are only two outcomes. Either countries want to understand that they will no longer issue excess currencies, issue additional currencies in a scientific and reasonable way, unify stable exchange rates, and maintain the credit system of centralized currencies, then the value of bitcoin will be infinitely close to zero. Or countries will continue to drink water to quench their thirst, and more frantically use the method of issuing excess currency to collect seigniorage from everyone, then the trust in the centralized currency will be lower and lower, and the total value of bitcoin, a decentralized currency, will be infinitely close to the gross labor value of all the units that do not trust the government and other governments, but need international trade
either the price is crazy or it's worthless
after understanding these, we can answer this question. Will bitcoin be replaced by other digital currencies
swindlers like * * and even the old Wang next door can come and yell, "I spent 10 minutes to change bitcoin's core and create a new digital currency called SBC. Come and join my ICO and pay me seigniorage ~". So, if this happens, will you immediately choose to use Lao Wang's SBC next door
the answer is that some speculators will participate, but the market will not. The reason is very simple, the new cryptocurrency has not been recognized by the market, the application has not been proced, this kind of currency has no way to exchange for means of proction. Then this kind of currency is not money, but a virtual commodity for speculation. In other words, even if old Wang ICO next door has an SBC, no one will choose this kind of currency except those speculators who have no brains
in the current market, there are many other digital currencies, such as Ethereum, EOS, XRP, and so on, which may have technological advantages in some aspects (in fact, BTC has been evolving, and it will also learn from the advanced technologies of other digital currencies that have been successfully proved by the market. LTC and other currencies can be said to be the experimental currencies of BTC's advanced technologies.), There may be more application scenarios than BTC in the future, but they are not likely to challenge the status of BTC. BTC will always be the first consensus in the currency circle, which is the belief of many people. BTC will exist for a long time as the gold in the currency market, not mainly for the circulation of digital currency
Since the birth of bitcoin, its price has risen from a few cents to a maximum of $20000. Although it has dropped a little, it has soared to $18000. This price surprised many people. Why is bitcoin such a virtual digital currency so valuable< the quantity of bitcoin is limited, so the price is relatively expensive. Because bitcoin can be anonymous, many people use bitcoin to hide property or trade. The speculation of bitcoin players leads to the high price of bitcoin First, the number of bitcoin is limited, so the price is relatively expensive< p> Bitcoin is a decentralized virtual digital currency, and bitcoin is generated based on algorithm, so the total amount of bitcoin will not exceed 21 million, and with the increase of mining population, bitcoin will be less and less, so the price of bitcoin is more expensive than other virtual currencies{ RRRRR}
the reason why bitcoin is valuable is that it has replaced part of the currency function and some people have speculated. If you have any other opinions, please leave a message to discuss
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 case, the cheated citizens all bought different amounts of "Regal money" on the Internet. In the end, they were unable to contact the payee, and all the websites were closed, which directly led to property losses
captain Zhang said that after the police investigation, it was found that most of the servers of this kind of financial management website were located outside China, which brought great difficulties for the police to investigate and crack down
in this case, all the cheated people learned about "Regal coin" through the "Regal 888" wechat group, and almost all of them were victims of "Regal coin" and were introced to the group one by one
captain Zhang also said that in this case, the cheated person was not allowed to trade within the first month after buying one yuan for one "Regal coin", but after one month, he could buy and sell at will
as more and more people put in money, the price of "Regal money" will be raised, some people will withdraw when they buy, and some people who invest in advance will withdraw when they taste the sweetness. Most of the subsequent "takers" dream of continuing to appreciate and buy in large quantities. When the organizers feel that there is enough money, they will run away Daqing (www.daqing.com)
