At present, a large number of businesses have accepted bitcoin
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.
although bitcoin still has great risks, after years of development, with the increase of its application population, application scenarios and application technology, no country or organization can completely eliminate it. If you can figure it out, it is likely that countries will generally accept bitcoin and embrace it
according to my personal judgment, bitcoin, after a period of continuous development, is likely to become a world currency in the future, which can play the role of electronic gold and become the target of the value of other sovereign currencies. From this perspective, bitcoin can be used as a means of asset preservation in the future when inflation is inevitable

The manager of a sushi restaurant in Japan said that for businesses, the service charge for using bitcoin to settle accounts is only 1%, which is very cost-effective and convenient.
It's not against the law to do bitcoin business, but don't use bitcoin to do illegal things

< P > users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to algorithms. When users "mine" bitcoin, they need to search for 64 bit numbers by computer and then, by repeatedly solving mysteries, compete with other gold miners to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, it will get 25 bitcoins
e to the decentralized programming of bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the upper limit of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

a single new server has the advantage of collecting herbs, which consumes a lot of water for reclaiming wasteland, and the inscriptions also use herbs
mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary. At present, mining is a very professional work, you need to buy a professional ASIC Avalon 3 generation miner for mining, and also need to join a mine pool
bitcoin is decentralized and not issued and controlled by any institution. Only bitcoin foundation is responsible for development and maintenance. The ore is free, but the equipment needs to be purchased. The exchange rate is high, which is a kind of trust in the bitcoin. It's a big social experiment. As long as you dig bitcoin, you won't worry about spending it. At present, thousands of businesses accept bitcoin around the world, such as the famous Dell company. There are also some businesses that accept bitcoin in China.
what currency is the most popular this year? I believe many people will answer: "bitcoin"
generally speaking, bitcoin is a kind of digital code, which is generated by a large number of calculations according to a specific algorithm. In theory, everyone can get bitcoin through calculation, which is compared to "gold digging" and "mining". According to the algorithm set by the founder of bitcoin, the total amount of bitcoin is limited, with only 21 million bitcoins. At present, 12.07 million bitcoins have been "g out"< However, it is not easy to dig out bitcoin. Lin Jia, a student of the school of economics and management of Beijing University of Posts and telecommunications, once made a special research. She said: "the performance of ordinary home computers is difficult to support the computing needed to" dig "bitcoin. There are special bitcoin" mining machines "on the market, and a high configuration one costs several hundred thousand yuan‘ Bitcoin is not only a high investment cost, but also a high technical threshold. The algorithm is very complex, so it is difficult for ordinary people to "dig" bitcoin by themselves. "
in fact, most people still buy bitcoin in cash. Bitcoin can not only be bought, it can also be sold. In some countries, bitcoin is even regarded as legal currency, which can be converted into real money and used directly for shopping. In China, some businesses announced that they would accept bitcoin payment<
if investors become the last stroke of drumming, they will only get a bunch of useless electronic symbols
recently, the central bank, MIIT, CBRC, CSRC and CIRC jointly issued the notice on prevention of bitcoin risk The notice stressed that bitcoin should be a specific virtual commodity, which does not have the same legal status as currency and cannot and should not be used as currency in the market. All financial institutions and Payment institutions shall not carry out business related to bitcoin
although a notice broke people's illusion of bitcoin becoming a currency in circulation, bitcoin still has a lot of fans. On December 16, the 24-hour trading volume of a bitcoin trading platform named okcoin in China alone reached 66225 bitcoins, with a trading volume of more than 300 million yuan
Why are people still so keen on investing in bitcoin? One of the important reasons is that many people think that bitcoin has a limited amount and can "maintain and increase value", and regard it as an investment tool like stocks and funds. In fact, investment in bitcoin was once very profitable. In the first four months of this year, bitcoin's value soared more than 10 times. In the short term, such a rapid rise has attracted a large number of follow-up speculators
bitcoin also falls sharply. On November 19, the price of bitcoin was fried to 8000 yuan, and then dropped to 2850 yuan on December 18, a month later
nevertheless, the bitcoin market is not in a slump, and even Lin Jia is going to "buy the bottom"“ A friend has bought bitcoin before and heard that he has made a lot of money, "said Lin Jia." I'm going to invest one or two thousand yuan to buy a few bits of bitcoin first. If I lose, I'll lose. Compared with the price of 8000 yuan, it may not be a high point now. Wouldn't it be good if we could make a profit? "
bitcoin charts, an international bitcoin website, shows that nearly 60% of bitcoin transactions recently come from the Chinese market. Many people share Lin Jia's "bottom hunting" mentality
however, the risk of bitcoin is not just the risk of price fluctuation“ Bitcoin is now more of an arbitrage tool than a payment tool, and its technical risk, security risk and regulatory risk are worrying. " Zhao Qingming, an adjunct professor at the school of finance, University of international business and economics, said frankly
first of all, from the perspective of the development history of the Internet, although the algorithm of bitcoin is complex, it is not impossible to be broken. Once broken, the whole system of bitcoin will collapse. Secondly, the private trading platform is not mature. Recently, a number of bitcoin trading accounts were stolen in Shanghai, with a loss of 640000 yuan. In addition, market regulation has not kept up. At present, the servers of many bitcoin trading platforms are built in foreign countries, and they are not registered in the domestic instrial and commercial departments, so it is difficult to protect the interests of investors< In Zhao Qingming's view, it is not advisable to buy and sell bitcoin with a speculative mentality: "bitcoin does not have the basic function of currency, unlike real gold and silver commodity currency, or paper currency credit currency with government credit support. Similar hype is not uncommon in Chinese history. Pu'er tea, Longjing and mahogany furniture also set sky high prices. If the investors who buy bitcoin become the last stroke of drumming, they will only get a bunch of useless electronic symbols. "
