Can graphics card dig bitcoin

1.

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

2.

Amd graphics card is recommended for bitcoin, n card is not suitable

moreover, one video card can't dig one coin a week, so it needs several amd video cards to dig together, and some even use mining machines. At present, mining on the computer platform is unprofitable for ordinary users unless they are professional players

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

4. Bitcoin was acquired by CPU in the early days, e to different working methods. CPU is mainly to do full-function operation, the number of core is small, and the operation ability is limited (GPU is a very large number of operation core for special operation). With the advantages of GPU general computing and the continuous development of GPU speed, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners. At present, it has left GPU computing. At present, miners have begun to widely use integrated circuit (ASIC) mining machine. Although this kind of mining machine can only be used to dig bitcoin, other currencies can not be used yet, but a single mining machine can reach the level of megabytes, especially loved by mine owners in Sichuan, Guizhou and other regions. Tens of thousands of professional mining machines are in full swing, and retail investors are unlikely to get bitcoin in the face of such powerful computing power.

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

6. Bitcoin is a distributed virtual currency without a central bank. The real value of this kind of currency depends on people's degree of speculation. If there are more speculators, it is very valuable. If there are fewer speculators, it can be said that it is penniless
brother, have you fried the futures trading category, how is it going? If you haven't even fired the futures, it's best not to mention it. To tell the truth, this is a virtual bubble. It's hot now, but once it is gone, it will be penniless.

7. A distributed ledger technology of blockchain! The jester of ether doesn't know what it is, so we should be cautious

8. There is an upper limit for bitcoin, which is controlled by a few people. Now there are too many people to dig, making it more difficult to dig. Digging for half a year may not be able to get back to the original. In the end, I worked for foreigners for nothing.

9. Mining only depends on the floating-point computing power of the graphics card, and nothing else, so it depends on the specific model of your graphics card
R9 280x / HD 7970 can dig two in three months on average
don't think about it. The worst way to mine is to use a graphics card above hd7850. Your hd7660d core display can't find one in a year.
