Difficulty of bitcoin in 2009

1.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 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

2. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and the core developer of bitcoin network, Jeff
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p

3. In terms of bitcoin, I calculate that it's about 0.13, earning 500 + yuan a day

4.

1 dollar = 1300 bitcoins. This is bitcoin. In 2009, 1 dollar = 1 bitcoin in 2011, 900 dollars = 1 bitcoin in 2013, and about 3880 dollars = 1 bitcoin on August 20, 2017. The highest price of bitcoin in history was on December 17, 2017, 19756 dollars per bitcoin

bitcoin is a virtual currency, and the total amount is set at 21 million, and the total amount is fixed. Bitcoin players can buy special video card miner to excavate bitcoin, and halve the number of mining bitcoin every four years until 21 million pieces have been excavated

so far, bitcoin has been halved twice, more than 17 million pieces have been excavated, and only about 4 million pieces remain to be excavated. According to some estimates, the last bitcoin will be excavated in 2140

General currency is decided by the central bank and virtual currency is decided by indivials. The sovereignty of general currency is in the center of the Republic; The sovereignty of virtual currency lies in distributed indivial nodes

from the perspective of information economics, general currency is a special case of virtual currency. The special point of this special case is:

first, the reference point remains unchanged. Therefore, value is specialized from a set to a recible value. When the reference point remains unchanged, value is equivalent to utility

Secondly, the gain and loss of utility relative to the reference point remain unchanged. This means that the value of reference point is a stable rational value and equilibrium value. In a rational economy, the reference point may remain unchanged, but it is still a scattered set. The difference is that every point (the actual transaction price) of this decentralization is unstable, and only the equilibrium value is stable

But in the value concentration of virtual currency, every point may be stable, on the contrary, the rational equilibrium value may be unstable. Reflecting on the monetary decision mechanism, the central bank is the personified representative of a fixed reference point of rational value, while the virtual money market (such as stock market and game money market) is determined by forces other than the central bank

It is in this sense that some people in economics call the stock market virtual money market and the economy formed by stock market and derivative financial market virtual economy. The essence of virtual economy is information economy with indivial as the center

5. I went to see it just now. It's sold on Taobao
now it's very difficult to download the program from the official website and do it yourself, but it may take several years. The second way is to buy it. Now it's about 18 dollars, less than 100 yuan. Mt.gox, bitcoin's largest trading website. On the official website of bitcoin, there is a paper by Nakamoto Tsung, which details the technical principles of bitcoin. In short, bitcoin is based on a set of cipher codes and generated by complex algorithms; Anyone can download and run bitcoin software to participate in the proction of bitcoin; Bitcoin uses electronic signature to realize circulation, and checks repeated consumption through P2P network
by 2140, the total number of bitcoins was 21 million. I suggest you buy it
if you still don't understand, it's suggested to search in the search engine: laoan, or Duan Hongbin, who has many blogs and is easy to find, and also has QQ. Add friends and let him give you< In 2009, a mysterious hacker named Satoshi nakomoto first proposed the concept of bitcoin, and described a method of using computer networks to create an unmanaged "secret currency". Unlike other virtual currencies, bitcoin is not issued by a company or a central bank, nor linked to any real currency, but can be used to buy goods and services in the real world. In essence, it can be seen as a small string of encrypted code quickly transmitted and stored in the electronic wallet on the Internet
just as the P2P networks such as Napster and Skype have made the record instry and telephone instry in chaos, bitcoin, which challenges the modern monetary and financial science, is also based on P2P, which is the same as the BT download technology we commonly use. The advantage of P2P is to ensure that no institution can manipulate the value of bitcoin or increase the supply to create inflation. In a huge P2P network, bitcoin has a special algorithm, which proces about 300 bitcoins per hour. The output is automatically adjusted by the network. Because you can't control most of the network nodes, you can't modify the algorithm of each user to speed up the money proction
figuratively speaking, bitcoin is "mined" by computers all over the world. If you want to get bitcoin, you just need to install mining software, and your computer will start to do a lot of calculations, which is mining
no matter which computer is used to mine, it is easy to get 50 bitcoins in the early days of bitcoin. As early as January this year, 50 bitcoin was not worth $15, but on June 9, a bitcoin was worth as much as $29.55. If you trade them, you can get back $1500 of real gold and silver. Now, however, mining requires high-performance computers, and some developers involved say that it is estimated that an ordinary laptop will work for five years to get a bitcoin.

6. No if
now in bitoffer, you can buy a bitcoin equity, that is, an option, for as little as $5.

7. Most businessmen and speculators are always interested in things that can be turned into money immediately. Bitcoin is one of them. The specialization of ASIC chips leads to the market separation between bitcoin mining and other Shanzhai coin mining
when the vast majority of video card mining machines and CPU mining machines are in a mine disaster, bitcoin mining with ASIC mining machines will not be affected. As the first big man in the virtual currency circle, bitcoin has become a deep-rooted belief in the coin circle. The total number of 21 million bitcoins also determines the transaction type and value-added of bitcoin
although bitcoin has begun to be recognized by most people, it has not really replaced the world's currency to fulfill its original intention, but it has become a collection beyond gold. The inflation of money, the rection of the total amount of mining and the increasing difficulty of mining all determine its future market prospects. The value-added has been firmly established, so people will rush to dig for mines, Because the bitcoin is actually worth more than gold

8. Since the outbreak of bitcoin, it has fallen. Many miners quit. They are cheaters. Don't believe it

9. After 2026 data blocks are generated by bitcoin, the calculation difficulty is updated (each data block includes about 25 bitcoins). It should be updated once today or tomorrow
the later, the longer it takes to calculate each data block, the lower the update frequency of calculation difficulty.
