Talk about what you know about bitcoin
Publish: 2021-05-23 16:43:02
1. To borrow the answers of others, this explanation is relatively simple
BT currency is a kind of virtual currency proposed by a Japanese in 2008 and officially issued in 2009
BT coin is like a gold mountain with a total amount of 21 million gold coins (the upper limit of the total amount is designed to be 21 million). To get it, players need to use the computing power of the computer to calculate a group of numbers according to the designer's algorithm, just like everyone working together or calculating a mathematical problem separately, each group of numbers can be obtained, Then you will get a BT coin, and the world can only proce 25 at most every 10 minutes. This calculation process is vividly called mining
of course, these mathematical problems are becoming more and more difficult. From 2009 to now, the output of BT coins is about 10.4 million. The more the quantity on hand, the more difficult the output will be. bitcoin is scarce. The upper limit of issuance (21 million) has been set. The difficulty of obtaining bitcoin increases geometrically. It is estimated that it will take hundreds of years to complete
it's ridiculous to say that it's an international QB. It's all virtual currencies, but the security and versatility of BT currency are incomparable to QB. TX is closed, QB is finished. But if BT currency is to collapse, it will not be possible unless there is a global power outage or the global Internet is paralyzed
with regard to the use of BT currency, the world has begun to accept the use of BT currency. Germany first recognized the legality of BT currency, and China also has a trading website BTChina, which can directly exchange BT currency into various current currencies of most countries, including RMB. In China, there are many sellers who accept BT coin on Taobao, and there are also many stores and supermarkets that begin to accept BT coin in Beijing, Shanghai and other large and medium-sized cities
just now, the BTC / RMB exchange rate in this second is 1 / 4888.03, which is still very valuable, but mining needs a lot of investment in advance. A professional mining machine (professional configuration for BT coin computer) is about 40000, 60 such machines work 24 hours, the output can be about 50. In addition to the astonishing power consumption and custody costs, the cost will be recovered in about a month. If you want to make money by mining your ordinary computer, it's a fable. If the owner has no capital investment, it is suggested to give up. The standard configuration of 5000 computers on the market, 48 hours of work also only dig out 0.001 BT coin... Thanks to grandma's house, the main reason is that there is capital investment in the building, so we have to hurry up. At present, it is estimated that the proction and income can still be profitable for 3 or 4 years at most. After this time, mining will not be able to make ends meet.

2. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. 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. 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 21 million.
3. Bitcoin system mainly uses hash algorithm and asymmetric encryption algorithm in cryptography to ensure the security of the transaction: on the premise of the transaction information being open in the whole network, the one-way property of hash algorithm protects the privacy information of both sides of the transaction; Asymmetric encryption algorithm can ensure that your bitcoin will not be transferred to other people's pocket ring the transaction< In theory, these cryptography principles can guarantee the realization of bitcoin's basic functions as a "decentralized currency", but it has some problems:
the first problem is system security:
we say that in the world of bitcoin, all information is expressed in the form of code through hash operation
then, where there is code, there must be loopholes, which give hackers an opportunity to take advantage of
as early as 2010, shortly after the emergence of bitcoin, a hacker took advantage of the vulnerability of bitcoin's core software to create hundreds of billions of bitcoins. It's like a person mastering the banknote printing machine. It's terrible. Or, hackers directly hack into our computers and steal our private keys, which will also cause us heavy losses
the second problem is that the transaction processing speed is too slow:
in the bitcoin system, there are up to seven transactions per second, which obviously can not meet the normal transaction requirements. We need to know that Alipay, Taobao and WeChat can handle hundreds of thousands or even millions of transactions every second. A deal can only be processed in 1-2 seconds. If bitcoin is used for daily money, then we will pay 1-2 yuan to handle it successfully.
the third problem is that bitcoin mining consumes too much power: Mining requires professional mining machines, which have high computing power, but consume a huge amount of power. Moreover, according to the current market, it is difficult to recover the cost of buying a mining machine for a year. Therefore, some people doubt: what is the significance of consuming so much power to maintain a system with such slow trading speed
the fourth problem is the regulatory attitude:
at present, the attitude of various countries towards bitcoin is very polarized: the supporting countries and retail stores accept bitcoin for payment, and there are also bitcoin ATMs; Countries that don't support it will crack down on it
to sum up, if bitcoin is measured by a monetary system, it must have various shortcomings. However, we can not deny the brilliance of bitcoin: bitcoin represents not only a new set of "decentralized" currency system, but also the origin of blockchain technology and a new ideology, which has far-reaching influence
from the perspective of bitcoin's own function currency:
bitcoin is the largest digital currency so far. It is an important application in the era of blockchain 1.0 and the first application of blockchain. Under the premise of decentralization, bitcoin realizes the functions of digital currency in the stages of issuance, payment and circulation, which is a new means of payment
from the perspective of bitcoin's underlying technology, blockchain:
with the increasing attention of bitcoin, blockchain, as its underlying technology, is becoming more and more well known by the public. Blockchain has graally separated from digital currency and penetrated into many commercial fields. Different instries hope to apply bitcoin Technology to our real life, Through a variety of application scenarios, let us get a better experience
from the perspective of bitcoin ideology:
it has set off a great ideological storm. The "decentralization" and consensus mechanism of bitcoin is a new ideology in the current centralized society. Throughout history, whether the Renaissance or the enlightenment, these are all ideological changes under specific historical conditions. The popularization of these new ideas and new consciousness will take a long time to be accepted by all. In terms of the influence of bitcoin:
digital currency has been accepted and recognized by some national markets, resulting in a large number of digital currency trading platforms and the emergence of a large number of counterfeit currencies. These counterfeit currencies have further evolved into a new financing mode, writing the myth of sudden wealth, which has also led to the proliferation of cheating under the banner of digital currency, such as air currency and pyramid selling currency
in short, bitcoin has outlined a grand blueprint, that is, the currency in the future will no longer depend on the release of central banks, but on the global currency unification. However, from the current situation, the blockchain 1.0 era, represented by bitcoin, only meets the basic functions of digital currency and cannot be popularized to other instries
however, in a word, bitcoin: there are shortcomings in the United States and China, and it is hard to cover up the edge.

5. You should want to know about bitcoin
but this is not a clear sentence. So now many people don't understand it and say it's pyramid selling or something
to put it in a word, it is a set of virtual world account books, which are used all over the world.

6. Bitcoin is a kind of electronic currency generated by complex algorithm
by analogy
ordinary currency is printed by the mint
bitcoin is calculated by the computer
the advantage is that the total number of bitcoin is fixed, 2100W, not controlled by any institution, and the circulation of ordinary currency is determined by the state
however, almost all countries do not recognize bitcoin as legal, and the price fluctuation is very large, constantly being hyped. I think that using bitcoin as an investment means is the same as gambling.

7. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system, which is a kind of virtual currency.
8. A kind of virtual electronic currency, which can be cashed out, can be used to exchange into the currency of various countries, can be used to buy online games, virtual clothes, shoes, and can be used for real goods if someone wants
9. Bitcoin is simply a virtual currency< What is bitcoin:

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< On February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency.
