Every country uses bitcoin

1.

There are only 21 million bitcoins

"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations

{rrrrrrr}

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 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

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

2. Bitcoin is a kind of P2P digital code. 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. The decentralized characteristics and algorithms of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin by mass manufacturing
bitcoin lacks stability, so it doesn't have "inherent value", it's just a virtual proct. If we recognize its legitimacy, it will have a significant adverse impact on the banks of all countries, and even can replace the currencies of all countries. Finally, a few people will manipulate the world's monetary system, which is a very dangerous existence. It's not money. Whether it's legal or not depends entirely on whether a country recognizes it as legal or not< At present, the United States, China and South Korea all think it is not a currency. Among the big countries, bitcoin is only recognized as the "unit of account" by the German Ministry of finance, but it is only a unit of account, which does not mean that it is mainly a currency.

3. Germany
at the end of June 2013, after the German parliament decided that bitcoin would be tax-free if it was held for more than one year, bitcoin was recognized as a "unit of account" by the German Ministry of finance, which means that bitcoin has been regarded as a legal currency in Germany and can be used to pay taxes and engage in trade activities< In August 2013, judge Amos mazant of Texas District Court ruled in a case of bitcoin virtual hedge fund that bitcoin is a kind of currency and should be included in the scope of financial regulation
legal status
bitcoin can still be considered as legal at present. In the world, bitcoin can be regarded as a virtual commodity and protected by law; If bitcoin cannot be officially recognized as a kind of currency by law, it may bring inconvenience to the businesses and indivials who accept bitcoin in tax declaration, because the businesses who accept bitcoin will be regarded as barter transactions, and such transactions are more troublesome than ordinary transactions in tax declaration
at the same time, bitcoin, as a commodity highly similar to currency, needs to meet the demand of anti money laundering. Bitcoin needs to be included in the personal property declaration, banking anti money laundering system, anti insider trading, anti market manipulation and other systems in terms of transaction and possession. Bitcoin exchanges and storage institutions may also need government supervision and licensing. Some fast-growing bitcoin exchanges and payment service providers are actively exploring cooperation with regulatory agencies to bring bitcoin payment into the regulatory framework of anti money laundering and anti-terrorism financing by applying for licenses and actively communicating with regulatory authorities
in Europe, the European Central Bank published a report on "virtual currency architecture", and the French bitcoin trading platform obtained the PSP qualification. On December 6, 2012, the central bank wrote in the report: "this report is the first attempt to provide a basis for discussing the virtual currency system. While these systems may play an active role in financial innovation and in providing consumers with alternative means of payment, they also clearly create risks. " "Because of the small size of virtual currency systems, these risks do not affect anyone other than the users of these systems," the report added The report reviews the history of bitcoin and reviews its basic features, including currency and technical operation.

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 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 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

5. Mining is that you help bitcoin network out of the computer to help witness the transaction, and bitcoin network gives you bitcoin as a salary. At present, the attitude of the international community is as follows: to recognize the status of currency: for example, the United States, Germany and other countries that recognize it as a speculative commodity, but do not recognize it as a currency; China and other countries that prohibit the use and trading of currency; Thailand, Russia and other countries that recognize that non recognition has little to do with mining, but it is mainly decided by the national system, just like some countries have freedom, In some countries, only the two countries that do not recognize it are: the prevention of the huge bubble of national speculation and the great risk (most countries have this worry) to prevent the rise of bitcoin from causing the status of the legal tender to be shaken (some countries consider it so).

Let's start with a simple conclusion: a year ago, the data showed that there were about 500000 BTC

two American brothers, Cameron winkleworth and Taylor winkleworth, claiming that they owned 1% of bitcoin [1] 1% of the world's bitcoin? At present, the total amount of bitcoin in the world is about 12 million, that is to say, the two brothers hold about 120000 bitcoins< maybe you don't think it's worth much, but note that the starting price of bitcoin for these two people is less than $10 / bitcoin

Please note that entities are used instead of people. In the analysis method of this paper, bitcoin wallets that may belong to the same owner are divided into the same entity, which may be not only a person, but also a trading organization like Mt. GOx in addition, through the analysis of the most active entity table given in this paper, the income of the people with the most income (excluding expenses) is less than 700000 BTC. In other words, the person with the most bitcoin will hold no more than 700000 bitcoins. How many people in the world own bitcoins? The paper concludes that as of May 13, 2012, 1.85 million entities hold bitcoin. If we assume that bitcoin users have grown linearly since the advent of bitcoin (January 2009), the current number should be 2.5 million. Because the number of entities is counted on paper, the actual number of bitcoin holders should be a little less than this number, but not much smaller, because after all, there are not many large trading platforms

In addition to the above two problems, [3] also gives many interesting conclusions, such as:

< UL >

about 55% of bitcoin can be saved without money

in places like GOx mountain, almost all deals are small ones

before May 2012, almost all large single transactions (& gt; 50000 BTC) are subsequent transactions of 90000 BTC on November 8, 2011. There are very strange patterns in this long list of transactions. For example, an entity divides 90000 BTCs into different sizes, sends them back to itself three times, and then sells them on Mt. GOx. 90000 BTCs sold are sent back to the entity through 90 different bitcoin addresses, with 1000 bitcoins per address. These operations indicate that the entity appears to be trying to hide the relationship between these transactions
