Virtual currency graphics card

Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

2. After high-speed computing with the computer composed of AMD graphics card, bitcoin can be generated
1. Unlike most currencies, bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm and is a virtual currency
2. In order to get bitcoin, you have to use computing machines, many of which are provided by AMD graphics card with high computing power. When bitcoin was hot, AMD's graphics cards were always in short supply, such as HD 7850, HD 7870, HD 5850, HD 5870, R7 270, R 280x, which are the best helpers of bitcoin
3. Later, when someone invented a mining machine that could get bitcoin more quickly, these graphics cards slowly withdrew from the mining stage
in other words, the computer made up of AMD high-speed graphics card was once the main platform for acquiring bitcoin. This is the relationship between them.

The virtual currency soared, and the graphics card for absenteeism insurance caused a heated discussion among netizens on the Internet. We have to say that we all know that the graphics card is an important part of a computer, which is what we know as the display adapter. mining also uses the chip to calculate a random number, and get the corresponding reward after getting the answer, Therefore, the graphics card is crucial and a very good mining tool, so there is a reason for players and miners to compete for the graphics card

I hope everyone can remember this. Although virtual currency is rising very fast and everyone wants to enter the market to eat meat, now is not a good time to enter. We all know that bitcoin is a Ponzi scheme. I hope everyone can realize this. We also hope that more and more people can work hard to earn money

In recent weeks, the high-end GPUs of almost all major foreign retailers have been out of stock. The price of high-end graphics cards has been soaring, and the shortage does not seem to end soon. Behind the unprecedented shortage of GPU is the influx of miners who are engaged in the exploration boom of Ethereum, bitcoin and other cryptocurrencies. It is difficult for game players to obtain one card. NVIDIA even implements "two cards for single user"

the main culprit for the shortage of graphics cards is that high-end graphics cards are the best way to tap Ethernet and other non bitcoin cryptocurrencies. With the popularity of blockchain concept in recent weeks, the price of these cryptocurrencies has risen to an unprecedented height. A powerful graphics card can dig up a few dollars in cryptocurrency every day. Therefore, more and more amateur miners began to compete for graphics cards, resulting in the shortage and high price of graphics cards for other non currency people

not only there is no high-end graphics card to buy, but also the manufacturer has informed customers that the return policy of graphics card is suspended

5. It's a trade secret. How can you send it to the Internet casually? It's suggested that you go directly to the shopping mall to do field investigation, and then analyze the short-term data according to the investigation to infer the data of one year. Of course, you can go directly to the person in charge of the shopping mall to ask, but basically people won't tell you
I have done a similar paper assignment before, which is about audio-visual procts. I went to a lot of places to ask questions, but they either didn't want to answer or gave me very general data

6. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal

7. After the completion of MLM or identification, it is important to remember that under no circumstances can you remit money first, whether it is franchise fee, deposit or other name,

8. Virtual currency is not a currency in China. In the bitcoin risk notice issued by the central bank and other five ministries and commissions on December 5, 2013, bitcoin is clearly defined as a special Internet commodity, which denies its monetary attribute and can not be used for payment, but people can buy and sell freely at their own risk. But people in the coin circle don't think so. Here is the view of the coin circle (take bitcoin as an example):

bitcoin has value because it is useful as a form of currency. Bitcoin has the mathematical characteristics of money (persistence, portability, interchangeability, scarcity, separability and identifiability) rather than relying on physical characteristics (such as gold and silver) or the trust of central power (such as fiat money). In short, bitcoin is backed by mathematics. With these characteristics, a form of money to have value requires trust and use. This can be reflected in the growing number of users, businesses and start-ups. Like all currencies, the value of bitcoin comes directly from people who are willing to accept it as a means of payment, which is the only source

some people with insight of digital currency in China are also beginning to explore application scenarios other than digital currency payment. Digital currency scholar Mr. Sha Qian mentioned the concept of currency business circle and planned many application scenarios of bitcoin. Perhaps inspired by the coin business circle, the jewelry instry has developed an applied digital currency, Fuyuan coin, which is similar to the traditional business integral.
