How many factories are there in bitcoin China

1.

The total number of bitcoins is 21 million

in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million

monetary characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a 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

2. Now it's not very profitable. In 12 years, the price of bitcoin was about 1000 +. With personal PC, we could dig more than one coin a week. The current currency price is about 20000 yuan
Development:
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. West Virginia Democratic Senator Joe; On February 26, 2014, Joe Manchin issued an open letter to a number of regulatory authorities of the US federal government, hoping that relevant institutions would pay attention to the current situation of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency. On January 11, 2017), the Shanghai headquarters of the people's Bank of China and the Shanghai Municipal Finance Office carried out on-site inspection of bitcoin China.

3. There are too many bitcoin factories in Shenzhen, but most of them are not real bitcoin factories, just OEM factories of bitcoin mining machines
nowadays, almost all mining machines need to be OEM. Shenzhen is the birthplace of bitcoin mining machine, but mining is mainly distributed in some remote areas in China
the mining methods of Ruitai coin and vitality coin are more interesting.

The concept of 21 million

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

bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million

generation principle

starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

5. Asicme, as well as roasted cat, now it seems that asicme has become the largest miner in China. I forget which news I read. The main procts of roasted cat are USB miner and blade miner, but the mining capacity is a little low and the price is relatively high. Comparatively speaking, asicme is more cost-effective. Hand fight, please accept.

6. It's not right to ask this question. Even if everyone has voted, it's a guess. Moderators should ask specific questions about "the number of bitcoin" and let voters choose which level they are in. For example, below 100b; 100~500B 500~1000B 1000~10000B Above 10000 B - let voters choose. I think most voters will express the real situation, because it belongs to anonymous voting.

7. Now I recommend my English tutor to you. I think this software is the best at present,

has strong speech recognition ability. You can listen to a dialogue first, and then choose roles and calculations to have a dialogue. If your pronunciation is not on time, the computer will automatically repeat accurate pronunciation until your comprehensive score of pronunciation (divided into several assessment items) meets the basic score of 80, At first, there are a few free courses. As you contact more and more, naturally, your et money (the virtual currency used by the software) will continue to increase,

then you can buy other courses, so it's very interesting. There are quite a lot of courses. Of course, you can also buy more courses through RMB,

with continuous practice, your own level will be higher.

don't mention the advantages, download and experience it yourself.

PS: every time you practice, you will download a new course (even if you have already learned it), so you need to have network support, and you can't run on a single machine.

8. In the game of drumming and spreading flowers, everyone has different opportunities to enter the market and different costs. For a single person, if the current market price is higher than the price he bought, he will make a profit. This part of the profit is brought by the market pushing up the price, that is, the entry of the latecomer raises the price and makes the first comer make a profit.

9. Only players, China's definition of bitcoin as a commodity, can not be paid as wages
there are three kinds of players:
1. Mining (procing bitcoin)
2. Investment (buying low and selling high to earn price difference)
3. Around bitcoin (such as procing mining machine to sell money, repairing mining machine to earn money, mining supporting business to earn money, etc.)

there is another kind, which belongs to the second category, but has a broad vision. It's the international pound. For example, the value of bitcoin in India is much higher than that in the world recently. Some people buy it in the world and sell it in India.

10. The total number of bitcoin is 21 million. It was g up in 2140, and the mining speed has been halved in four years. At present, more than 13 million bitcoins have been mined. Bitcoin was invented by a man named Nakamoto, who disappeared in the bitcoin circle after 2010. No one knows who this person is.
