How much bitcoin does the Fed hold

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. The total amount remains unchanged. It's easy to understand that the total number of bitcoins will not change. Developers are public, but they don't have private ones.
but they can be divided down, and there's nothing hard to understand. I have 1 yuan in my wallet. I can also say that I have 10 Jiao, 100 Fen, 1000 Li, 10000 milli, 100000 silk, 1000000 Hu, 10000000 micro. No matter what the unit of measurement is, I will neither become richer nor buy more, nor have any impact on the economy.

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

4. The total amount is 21 million, about one block is proced every 10 minutes, and the number of bitcoins in each block is 12.5 after being halved twice, that is to say, 12.5 bitcoins are proced every 10 minutes

5. 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

bitcoin is used for graphics card mining. It used to be OK, but now there is almost no profit from using graphics card mining. Of course, if your electricity is free, it's OK. The graphics card mining you mentioned is the second stage of bitcoin mining. The first stage is mining with CPU, which is an ordinary computer. The second stage is the graphics card mining you mentioned, commonly known as burning graphics card. At present, it has entered the third stage of ASIC mining machine mining stage. In this stage, the computing power is very high, the mining income is very low, and the mining cost is almost close to or even more than the currency price. At present, the profit of large-scale mining mainly depends on the energy consumption of mining machine and the advantage of electricity price.

6. When the first cryptocurrency, bitcoin, came out in 2009, it was worth less than 10 cents. Since then, the price of bitcoin has risen steadily, reaching an all-time high of $20000 at the end of 2017. It is undeniable that in the past 10 years, because of bitcoin, the cryptocurrency, many billionaires have emerged
with the continuous popularity of bitcoin among cyber criminals and its growing presence in criminal activities, "Uncle Sam" (personified name in the United States) has become an important participant in the cryptocurrency market. Although the exact number cannot be determined, according to the documentary evidence and previous and current interviews with defense lawyers and prosecutors, there is at least one billion US dollars worth of digital currency, which is currently under the control of US law enforcement agencies
the investment method of bitcoin is very simple. Search "tacu Asian Stock Exchange". After registering and logging in, follow the prompts to invest in bitcoin. Now you can also give free digital currency for registration. This is a transaction registered in Thailand. The Thai royal family has a share in the transaction, and the credit is guaranteed. I registered on this platform and sent 1000 coins, with a maximum value of more than 10000 yuan. If you have other problems you don't understand, you can solve them by contacting customer service directly.

7. Regal money is a pyramid scheme, which is different from the mainstream currencies such as bitcoin, Ruitai and Laite. The following is the disclosure of the media:
in the case, the cheated citizens all bought different amounts of "Regal money" on the Internet. In the end, they were unable to contact the payee, and all the websites were closed, which directly led to property losses
captain Zhang said that after the police investigation, it was found that most of the servers of this kind of financial management website were located outside China, which brought great difficulties for the police to investigate and crack down
in this case, all the cheated people learned about "Regal coin" through the "Regal 888" wechat group, and almost all of them were victims of "Regal coin" and were introced to the group one by one
captain Zhang also said that in this case, the cheated person was not allowed to trade within the first month after buying one yuan for one "Regal coin", but after one month, he could buy and sell at will
as more and more people put in money, the price of "Regal money" will be raised, some people will withdraw when they buy, and some people who invest in advance will withdraw when they taste the sweetness. Most of the subsequent "takers" dream of continuing to appreciate and buy in large quantities. When the organizers feel that there is enough money, they will run away Daqing (www.daqing.com)
