PC and calculation power of mining machine

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

{rrrrrrr}

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics

the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

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

4. The desktop can't be g down at all. You can try something else. I'm just digging ITGC, which costs dozens of yuan a day.
the most important thing is that the ITGC client has built-in one click mining! One click mining! One click mining! Important things are to be repeated for 3 times. For Xiao, in fact, mining is not so difficult, as long as there is a computer, a mobile phone can, today teach you a key mining
first of all, we need to download ITGC's wallet client. We can search eppool, Download professional mining tools, and now support PC's win, Linux, MacOS's CPU and graphics card mining, as well as Android mobile phone mining! The second step is to download the official wallet client. After downloading and installing, we start ITGC wallet. Step three, start mining Mining command] enter go and enter to start your mining journey. It's so simple! It's amazing!

web link post bar example:

we will calculate the graphics card to dig bitcoin earnings

assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s

HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days

OK, all the parameters are ready, calculation
in calculation...

eh, how come it's a negative number

because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low


suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950

6. Mining machine can't be used as a computer, it can only be used for mining. Mining machine is certainly better than computer.
home computer can't even earn back the cost of digging bitcoin
at present, the home computers all dig up the Leyte coin, because there is no special Leyte coin miner, so it should be able to earn money
hope to adopt.

How to dig bitcoin:

< UL >

01

first, download a bitcoin e-wallet from the Internet. It should be noted that the wallet is very large

06

finally, fill in your miner's information in your mining tool. User name should fill in the miner's name. Remember to add the miner to your email in the form of your registered account

8. Young man, be realistic. It's unrealistic to mine. If you take home computers to mine, don't use machines?!

9. Buy those with credit but no strength reserves, such as bitcoin, but I think it's better to buy Maotai stock. Although Guizhou Maotai stock circulation does not apply blockchain, its conscience returns absolutely attract money.
