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

3. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. 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 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 currency 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
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[ 1-2]

4. It's not sure that the fastest one will get these 25 coins, but the faster the calculation, the higher the probability of getting these 25 coins ~
and it's not necessarily 25 coins every 10 minutes. The generation speed will be slower and slower, until 21 million bitcoins are g out, there will be no new coins. When the time comes, the miners can only make money from the service charges voluntarily paid by some people.

5. The concept of virtual currency
bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

6. Political function and economic function

because bitcoin has the following potential risks: first, high speculative risk; Second, high risk of money laundering; The third is the risk of being used by criminals or organizations. From the perspective of maintaining national security and social stability, it is a political function; It is an economic function to manage and supervise the enterprises and the market by ensuring the smooth operation of the market, ensuring fair competition and fair trade, and safeguarding the legitimate rights and interests of enterprises

bitcoin home has the notice and interpretation about the central bank and other five ministries and commissions

from the current situation, because the total amount of bitcoin is small, the scale of trading market is limited, and financial institutions are not directly involved in trading and investment activities. As long as necessary prevention and control measures are taken, the risks brought by bitcoin and other virtual commodities can be avoided to impact the financial system and affect financial stability and monetary policy. At the same time, as a virtual commodity, bitcoin's price fluctuation is not related to the real economy, and the scope of real economy transactions priced and paid by bitcoin is extremely limited. We can also strengthen prevention and control to avoid bitcoin and other virtual goods to impact the real economy. However, e to the high risk of speculation, money laundering and being used by criminals or organizations, bitcoin and other virtual commodities are still worthy of attention

since the emergence of bitcoin China, the first bitcoin trading website in China in 2011, dozens of similar virtual commodities have appeared in China in just a few years, and more than ten trading websites of bitcoin and lettercoin and other similar virtual commodities have been set up. The daily bitcoin trading volume in peak period accounts for more than half of the world's bitcoin trading volume. With the help of the concepts of "internet currency", "future trend" and "digital gold", the trading of bitcoin and other similar virtual commodities has changed from simple trading to high-risk speculative activities such as "financing currency" and leverage trading. Compared with bitcoin, there is still a lack of sufficient understanding of bitcoin and a large number of ordinary people participate in it, Holding, using and trading bitcoin out of the mentality of following the trend or speculation will cause great losses. If it is not restricted, it will not only affect the seriousness of RMB as China's sovereign currency, but also damage the property rights and interests of the public.

7. Housing mortgage purchase proceres:
1. The commercial housing purchased by the buyer must be the commercial housing of the real estate development company which has signed a mortgage agreement with the bank
2. Sign the house purchase contract with the real estate development enterprise, and pay the down payment according to 20% of the total house purchase price
3. Submit an application for housing mortgage loan to the bank and relevant information
4. The bank shall investigate the borrowers and the information provided, and inform the borrowers to go through the loan proceres if they meet the conditions
5
6. The borrower will mortgage the purchased commercial housing to the bank, the real estate enterprise will register with relevant departments for mortgage, and submit the "other property ownership certificate" to the bank for safekeeping.

8. Different stocks are going up because of their good performance, that is to say, the strength of the company is improving and becoming more and more valuable. Virtual currency is going up because it is as rare as stamps. One hundred sets of this one is not available, so it's expensive. But the question is, does anyone accept the offer? In case there are many virtual currencies coming out tomorrow, XX currency, XXX currency, that is, the number of bitcoins is certain It's not like gold. There's so much gold. But virtual currency is virtual code. It says that writing can write gold. Can you make it more? So virtual currency is not the mainstream, but the most auxiliary thing. The value is not too high. Don't think that people are good when they buy. People follow too much. In the past, Auntie was crazy when she bought gold. Now why is she rational Money ah, stocks, migrant workers have bought stocks, and now how not to buy or lose money, real estate is also the same, and so many years after the collapse will be rational

9. 1. Since bitcoin became popular, blockchain has been in a mess. The main reason is that bitcoin has created a kind of scarce electronic carrier. No one can arbitrarily increase the number of electronic carriers through cryptography

2. The purpose is that the global currency, as far as the world's central banks are concerned, has the power to arbitrarily increase the money supply, leading to currency devaluation and stealing the global people's labor income

3. Therefore, this carrier can't be changed arbitrarily. Some people will regard it as a currency carrier. Just like the gold and silver of that year, these currencies of that year can be used as currency carriers because of the scarcity of non-ferrous metals

4. What's the use of money carrier? It's for circulation and preservation. If the central bank has restrictions, it is not allowed to increase the money supply at will, so that people's labor income will depreciate. In fact, electronic money is the most convenient. How heavy is gold and silver? Even the transaction of bitcoin is very inconvenient and cannot be used as a currency transaction

5. So, as long as someone believes in it, as long as someone is willing to hype it, there will be a price. If you think about it, the price of tulip, which was scarce in those years, could fly as long as it was hyped

6. When everyone thinks that this thing is meaningless and not hyped, then there is no price for this thing.
