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. The number is about 50000
3. For the hard bifurcations of bitcoin network, the foreign market is very calm. As the largest trading market of bitcoin in Japan, the development of bitcoin in Japan has experienced twists and turns. After the bankruptcy of Japan's largest bitcoin trading platform in 2014, the bitcoin market once fell to the bottom. However, recently, the trading volume of bitcoin in Japan has increased sharply again, and the application scope of bitcoin is also expanding

coincheck is one of the largest bitcoin trading platforms in Japan. At present, the total monthly transaction amount of this platform has increased from about 3 billion yen at the beginning of last year to 36 billion yen now, expanding 12 times. As for the development of the platform, the president of coincheck, a bitcoin trading platform in Japan, said that in the near future, one bitcoin can be exchanged for 140000 to 150000 yen (about 8700 to 9300 yuan), which is 2.5 times higher than that of the same period last year, and the total number of users registered on the major bitcoin platforms in Japan has exceeded 600000.

among the prosperous shops in Ginza, Tokyo, Japan, You can also see a bitcoin trading machine that can exchange invisible bitcoin and yen notes. People choose to buy, sell and other operations in the trading machine interface, and can easily complete the transaction by scanning the two-dimensional code of the bitcoin wallet on their mobile phone. At present, there are six such bitcoin trading machines in Tokyo and 14 in Japan

in Japan, more than 4200 businesses have accepted bitcoin payment. At this sushi restaurant, when customers check out, they can choose to pay by scanning the QR code of bitcoin bill. Since the introction of bitcoin payment system into the sushi restaurant, the turnover generated by bitcoin payment in one month has reached 500000 to 1 million yen, equivalent to 30000 to 60000 yuan. 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.
4. 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).
5. Take line 5 from Metro cultural center station to xiawafang station, and then transfer to line 1 to Nanlou station

blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more

In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently

extended data:

type of blockchain

1, public blockchain

any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world

2, Alliance (instry) blockchain

instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain

3, private blockchain

only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes

7. There are a lot of them. The big three, Huo coin, Qian'an and okex, should be the best.
8. At the latest, the examination fee (if it is a make-up examination, it is a make-up examination fee) should be paid on the day before the examination. If you don't pay the examination fee, even if the appointment is successful, you can't print the admission card in the examination room on the same day, and you can't participate in the examination normally.
