Financial currency bitcoin

bitcoin is a kind of electronic currency / network virtual currency

bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

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

extended data:

currency features:

1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no 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

advantages of bitcoin:

1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm

2, anonymity, tax exemption and supervision free

3, robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear

4, borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records

5, Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency

but these counterfeit currencies are very fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency

many counterfeit coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical

the weakness of bitcoin

1, the fragility 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

2, 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

3, 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 trading

4, 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 distinguish 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

Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below

bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"

Nakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is

bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin

What is blockchain? How far is it from our life? A Alipay warm dad engineer used a fairy tale to explain the problem. p>

however, after watching the story of rat king, the boy named big asked his father a question when he made a video phone call with his father: where did big come from? Can this process be traced by blockchain

One of Asia's largest banks, DBS, recently said bitcoin is a financial fraud

he is not the first person to take a negative attitude towards digital token. In the end, Gledhill predicted that the pricing of bitcoin would become "very cheap", adding that bitcoin would not help DBS bring customers, deposits or wealth management
