Bitcoin website BG's point of view

1. bitcoin is different from the previous currency, it completely relies on the Internet to create and trade; Bitcoin's unique technical attributes lead to its economic and cultural attributes beyond the present currency. Bitcoin is a kind of electronic currency proced by open-source P2P software. Compared with the paper currency in circulation, the biggest feature of bitcoin is decentralization and global circulation in the network world, followed by high security and high confidentiality. These technical attributes further extend to the economic attributes of no inflation, no freezing, and no man-made supply; In terms of culture, bitcoin is popular among anarchists and liberals. The advantages of bitcoin are artificially exaggerated, and its anti inflation and anti inflation functions cannot stand up to scrutiny. In the long run, the prospect of bit is hard to match that of gold. In the most optimistic case, it will become a means of payment in some areas; But in the short and medium term, bit still has room for speculation and imagination. In addition, the use of bitcoin in some sensitive areas highlights the increasingly prominent role of information in national security
1. The advantages of bitcoin are exaggerated: About decentralization, no transaction costs and anti inflation
it is true that bitcoin has various advantages over paper money, but these advantages have been over interpreted. First of all, bitcoin is a kind of decentralized currency, which will not have the same risk of central bank controlling money supply and affecting market value as paper money; Bitcoin is mainly held in the hands of large investors, and the market depth is not enough. At present, the trading behavior of large investors is also very easy to affect the price of bitcoin. Even if the attribute of decentralization is regarded as the advantage of bitcoin when it is fully mature, then the prerequisite of holding decentralization should be added. In addition, there are great differences between centralized and decentralized online payment systems in the degree and type of financial risks they are exposed to
secondly, the low transaction cost of bitcoin is not without transaction cost. On the contrary, e to the increasing difficulty of bitcoin mining and the further stability of currency value, the dependence of relevant transaction platforms on transaction cost will increase, which will certainly increase the transaction cost. Finally, the confidentiality of the bitcoin transaction needs to be discussed. The principle of the bitcoin transaction makes all the processes of each bitcoin transaction stored in each machine. If someone can determine the real background of a transaction, they can find all the transactions down and up through these data
compared with other advantages, anti inflation or anti inflation is the most publicized advantage. Although its supply is stable and the upper limit of supply is locked according to its algorithm, unless the whole world is unified and all countries use bits as currency, it can not prevent the over issuance of money only as a means of payment or a storage of value, just as the current existence of gold can not constrain the growth of each country's currency. If bits can only be used as a means of payment in local areas (such as the network), then global or some countries' inflation will still be transmitted to the areas where bits are used. Therefore, the use of bits to prevent inflation is basically untenable, or has a strong premise. As for anti inflation, that is to say, it has the function of value storage, it needs to have the property similar to gold. However, from the reality, bit's essential property and prospect are still hard to match gold. See below for details
2. Bitcoin's future positioning is too high
the expectation of bitcoin's future in the market generally compares it with gold and US dollar, which is relatively high. The recognition of gold not only lies in its natural physical properties, but also in its official acceptance as a reserve currency (or an important allocation of foreign exchange assets). In theory, bitcoin as an electronic currency does not have the unique and exclusive status, and it is more difficult to become the official reserve of central banks like gold. Therefore, it is not appropriate to expect too much bit. As an electronic currency, bit has the first mover advantage. If it can be guaranteed in terms of security, its most optimistic prospect will be as a means of payment in local areas
3. Speculation and speculative demand caused by event factors are the main reasons for the rise of bitcoin in this round
under the credit currency system, people's lack of confidence in the currencies of various countries and pessimistic economic prospects are the general environment for the rise of bitcoin in this round. The speculation of the major dealers in the market and the derivatives market of bitcoin, together with the speculative psychology of the participants, further accelerated its rise. Btcchina's investment of US $5 million and the announcement of Ben's position are the main driving factors for the recent surge
however, a lot of big players start to enter the market and buy a lot, which not only drives the bit price up to a high level, but also increases the market risk. Chamath, a former Facebook executive, has spent $5 million on bitcoin and plans to spend another $10 million. Bitcoin investment trust also exceeded its target within four weeks, raising $15 million. These people's investments not only make bitcoin further rise, but also concentrate on the holding of bitcoin, which strengthens the influence of indivials and institutions on the price of bitcoin and increases the market risk
4. There is still strong room for speculation in the medium and short term
although our previous analysis is not optimistic about the prospect of bit, it is likely that bit will still have strong room for speculation in such a short and medium term period of time as one year. As mentioned in the previous analysis, the creators of bitcoin advocate that the generation of bitcoin is not manipulated by human factors, which is quite different from the credit currencies of various countries. We expect that the monetary policies of major countries will be divided next year. With the release of economic risks and the heavy damage to traditional asset markets, bitcoin will have better room for speculation and imagination< The use of bitcoin in some sensitive areas highlights the increasingly prominent role of information in national security
the U.S. government seized the drug trading website "Silk Road" at the beginning of last month. A crowdfunding network called "assassination market" even marked the sale of murderers with bitcoin price. The founder of the assassin market, under the pseudonym of kuwabatake Sanjuro, is an extreme anarchist. Both prism gate incident and the use of bitcoin in relevant sensitive fields highlight the increasingly prominent position of information field in national security. The Third Plenary Session proposed the establishment of the national security committee, which will play an important role in China's security strategy and expand from traditional national defense, stability maintenance / urban security to information security and other emerging areas

Bitcoin is a kind of P2P digital currency
reasons for blocking:
1. Vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
The transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed The price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading4. The public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
the decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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 millionbitcoin 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 the relevant authorities 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
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
3. Now it's March 2021. I'll answer you. What are bitcoin and Ethereum? These two are the virtual money that grabs money and the new things that drive the nationwide mining tide. Bitcoin is now 1 = 350000 RMB. In this way, Ethereum is 1 = 11000 RMB, and its value is rising. I regret that I just heard about bitcoin when I was studying in 2008, but it's only 20 yuan, I didn't buy a 200 yuan plug-in. Now it's worth millions of money with me.

historical background
bitcoin is one of the first currencies to realize the concept of "cryptocurrency". In 1998, Wei Dai first expounded the concept of "cryptocurrency" in cypherpunks mailing list. Based on the basic concept of money, which is used to pay for goods, services and debt or any form of records in a given country or economy, bitcoin is a new form of money. Its original design is to integrate the idea of not relying on the central authority, using the principle of cryptography to control the issuance and transaction of money
in 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto claimed that he had transferred to other affairs and left the project. The creator of bitcoin never revealed his true identity, but left his invention to the world. Today, the origin and motivation of the invention of bitcoin is still a mysterious story
since 2010, many developers have devoted themselves to this project, and the bitcoin community has grown rapidly. Between June and July 2011, bitcoin suddenly gained media attention, leading to large-scale buying. The resulting bubble led to the continued decline in the price of bitcoin in the second half of 2011. After that, the price of bitcoin graally rose to the height of 2011
in order to regulate, protect and promote the development of bitcoin, the bitcoin foundation was established on September 27, 2012. Nowadays, with the increasing number of bitcoin users, bitcoin economy is developing rapidly
technical features
any network like bitcoin has the following basic features:
bitcoin can be transferred between any node of the network
the transaction is irreversible
the use of block chain avoids the occurrence of double consumption
the transaction will spread out in a few seconds and pass validation in 10 to 60 minutes
transaction processing and currency issuance are carried out through mining
bitcoin can be received at any time whether it is online or not<
economic rules
the whole bitcoin network jointly implements the following rules:
the total amount of bitcoin issued is about 21 million
a bitcoin can be divided into 8 decimal places, with a total of about 21 × 1014 monetary units
transaction costs are very low and most of them are free
statistics
bitcoin network has been running continuously for more than 48 months. In the past year, bitcoin's security features have attracted attention and developed significantly. As of April 2013:
the longest block chain has more than 232000 blocks
one of the largest distributed computing networks in the world, with more than 65 trillion hashes per second
there are 50000 transactions every day, with a total amount of several million US dollars
the total value of bitcoin in circulation exceeds US $1.3 billion
there is only one major security incident in the protocol, which was resolved in August 2010

5. Professor Lang Xianping warned: bitcoin is a complete financial fraud. People should take care of their wallets, cherish their lives and stay away from bitcoin
everyone has his own views on new things, which can not be covered in a word. Everyone has their own theoretical basis, but whether bitcoin is a fraud still needs to be tested in practice. There is no right or wrong point of view, and practice is the only standard for testing truth. Bitcoin is just a small-scale social experiment. However, with the rising tide of bitcoin, many well-known counterfeit coins have been derived, such as Wright coin, dog coin, Ruitai coin, Weimeng coin and so on. However, pyramid schemes under the guise of digital currency are also increasing.

6. The general idea of "fragmentation" is to change each block in the blockchain network into a sub blockchain, in which several (currently 100) collations (which can be called "check blocks", in order to distinguish them from the concept of blocks in the scenario of fragmentation) packed with transaction data can be accommodated, and these collations finally form a block on the main chain; Because these collations exist as blocks as a whole, their data must be packaged and generated by a specific miner, which is essentially the same as the blocks in the existing protocol, so there is no need to add additional network confirmation. In this way, the trading capacity of each block will be expanded about 100 times; And this kind of design is also concive to future expansion. At present, the whole expansion plan is roughly divided into four stages; This article only introces the implementation details of the first phase. Transferred from Jianshu.

9. What is bitcoin? What's the use of Internet? On the evening of the 12th, the computer blackmail worm named "eternal blue" broke out on a large scale in the world. It is said that "eternal blue" has spread to more than 100 countries, including Europe, the United States, China, etc. according to incomplete statistics, there are more than 1 million computers in the world, most of which are local area networks of universities and scientific research institutions. It is estimated that in the past 24 hours, about 150000 people have paid ransom to hackers through bitcoin trading platform. If this estimation is reliable, the amount of bitcoin that hackers have obtained is about 600 million yuan. If there is no accident, more people will pay ransom in the future. The amount of blackmail is estimated to be more than 10 billion! First of all, bitcoin does not belong to any country, indivial or organization. It is an uncontrolled and decentralized currency. Kun Peng made a search on it. In fact, bitcoin has been used as ransom in the early years. The method has not changed much. It's all encryption and blackmail. The person in charge of F-Secure, a network security company, once said that the encryption and blackmail software has become their biggest headache. Once the computer is infected, not only the hard disk drive is encrypted, but every file will be invaded. Although such incidents have emerged one after another in the past, it's only that they didn't have as much impact in the past as this one. Besides, people like to forget most, so they are not well known and it's normal. For example, around 2013, hackers began to extort bitcoin by illegally encrypting users' PC data and personal information. In 2014, an Australian executive was harassed by hackers after he paid $14000 worth of bitcoin ransom for malware under the pressure of online hackers. In 2015, hackers launched a third cyber attack on three Greek banks and demanded 20000 bitcoins (worth 7 million euros) as ransom from each of them. In 2015, the police department in tuxbury, Massachusetts, was attacked by hackers, resulting in the computer unable to log in. In order to prevent the loss of important data, the police station finally paid 500 bitcoin "ransom" as required by hackers. In 2016, a hacker hijacked the network of the Hollywood Presbyterian Memorial Medical Center through software, paralyzing the operation of the hospital. The hospital decided to pay 40 bitcoins, equivalent to about 17000 US dollars, as a "ransom" to the hacker Kunpeng believes that hackers choose bitcoin mainly because it has the characteristics of decentralization, globalization and anonymity like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields. Moreover, bitcoin can be used to cash, which can be converted into the currency of most countries. Bitcoin investors generally believe that the reason why hackers choose bitcoin to pay ransom is that bitcoin not only has advantages over other traditional payment tools, but also is the best choice among other virtual currencies. Firstly, bitcoin has certain anonymity, which is convenient for hackers to hide their identities; Secondly, it is not subject to geographical restrictions and can collect money on a global scale; At the same time, bitcoin also has the characteristics of "decentralization", which allows hackers to automatically process the ransom of victims through programs. With the technical support of the network, the manufacture and issuance of bitcoin are not based on the trust of the central issuing institution, and the operations such as transfer and other transactions do not even need names. That is to say, to collect money with bitcoin, you don't need to open an account in the real name of a financial institution, and you don't need to go through any third-party institutions, such as the third-party payment that we use most at present. You just need to download and register an independent bitcoin wallet. If what the criminal extorts this time is not bitcoin, US dollars or other currencies, and what the criminal gives is not a bitcoin wallet address, but a collection account of a bank, the hacker may have been locked or arrested before receiving the money. Now you know, anyway, I don't need bitcoin. Please pay more attention
10. Personally, I feel that bitcoin has no impact on finance. It has fallen too much, and there is no profit at all. To make money, we have to go to a new trading platform. What kind of bock is a platform with great potential, OK
