How much is stolen from the video card mining pool
Through a specific program and algorithm, using the computer graphics card calculation rate, a large number of calculations are carried out in the selected mine pool to generate data packets
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
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:

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
this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times
bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds
most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management
First of all, which brand is 580
Second, the difference between N card and a card is also different
n card not only supports OpenCL mode, but also CUDA mode mining device is available. In CUDA mode, the performance of gtx580 is 30% higher than that of OpenCL mode. In CUDA mode, not only the performance is improved, but also the power consumption ring mining is reced, from 366 watts to 329 watts. This shows that the algorithm efficiency of CUDA mining is better than that of OpenCL mining, but e to the limitation of its own computing power, it is not as good as a card with massive stream processor
how much can be mined is to be tested
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
as a middle-aged miner for 13 years, let's talk about the feeling of mining before.
I bought four mining machines in the past. Bitcoin uses CPU and I'm not familiar with it, so I use the form of buying graphics card to dig Wright's coin.
the first one is a simple double card mining machine, not a mining machine strictly speaking, but a double 7950 machine, At that time, I thought about digging for a while. If I didn't make money, I could still play games by myself. As a result, I found that the efficiency was really not high. Later, I used to dig some dog money and play with it.
the second one was the popular 6-card miner in those years. At that time, there was a powerful motherboard, which could run for 6 yuan by connecting with the PCI adapter and changing the BIOS. At that time, I could dig a lot of Wright's money every day with this machine, It's a pity that there are too many people digging, so it took more than 80 days to dig the coins. The third and the fourth are professional mining machines. At that time, the new chips were used to mass proce mining machines. Although they were expensive, the power consumption decreased a lot. It took about a year to dig, In the end, he retired, g up other counterfeit coins for a while, and then sold them.
generally speaking, many websites have no credibility at all in the past few days. They actually know what the concept of excessive increase in computing power is after digging up the money.
when ZF suppressed it, the assets immediately shrank by nearly 70%, but they still didn't sell because of their faith, On the contrary, after selling the miner, I bought some coins and put them in my hand. When I bought 100, I g them and only bought 15. Hey, the miner was sealed and put under the bed. After waiting for three years, I found that it rose again. This year, when bitcoin rose to 2W, I sold some Leyte coins and paid the down payment. Almost 300 of them were sold. Now it seems that the highest is 380, Ha ha
now I still have some money in my hand, and I plan to hold it for a long time, but I won't dig any more. However, I still have a lot of orders with our first-class suppliers. In the past two months, I sold nearly 150 cards, and the more I sold, the more I sold. Some cards are about to double, which is even crazier than that in 2013, The existence of e-money has its own value in the end, but it does not deny that there are so many speculators who come in to fight. There are indeed those who pursue the price. After the boom, there will be a wave of leeks cutting. In the final analysis, bitcoin is just an investment. Everyone feels different about the risk. The strength of big funds is still strong, and it is inevitable for retail investors to be cut, But it's better than A-share at least.
mining is not a good thing. The big miners are in the remote areas with low electricity charges, many mining machines and low cost. Most people dig at home, and that's just a little fuss.
finally, it's not a good thing to grow too fast. Those who are confident can come in and show their operation. If they don't have much ability, don't come in, Only by routine
at present, 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.
How long can video card mining last? How many hours is the working life of graphics card mining? For this problem, first of all, the score is clear in two cases, one is the use of new graphics card, the other is the use of old graphics card, the working life is naturally different. If you buy Mining host configuration used graphics card, working life is not easy to say
However, it is worth mentioning that digital currency trading has been closed in China, so users who want to mine should be cautiousthe above is a brief introction of "graphics card mining life"! Hope to help you
