Mining cost of graphics card in 2018

1. CPU can be used to mine, but the efficiency of CPU mining is not as high as graphics card. In order to make money, absentees have to calculate the input-output ratio. The input-output ratio of mining with graphics card is higher, so we graally start mining with graphics card. Now you should understand why mining with graphics card does not use CPU.

2.

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

3. HD5870 graphics card
built in 1600 stream processors

pay attention to the number of stream processors in mining

and this graphics card is very affordable now

4. Why can't I buy it:
1: the working state of the mine card is 24 hours a day, full load and complex floating-point calculation, which does great harm to the original of the graphics card itself. The mine card mines for one day. Equivalent to about 10 days for ordinary users. So buy mine card is very easy to damage
2: as long as the graphics card is used in mining, the manufacturer will not guarantee it, or only guarantee it for half a year. Now, when you buy a graphics card, there is a label on its shell: "if the graphics card is used for mining, there is no warranty in case of problems".

5. If you can, it is recommended to go to the loan, regular. If it's a business, it's recommended to look for venture capital. In short, it's not recommended to go mining. There is no life safety guarantee. Regular is two shifts, five hours a shift, a month down about 23000

6. There is no need to set it manually, let the computer manage it automatically. 1. The recommended value of Microsoft's virtual memory setting is 1.5-3 times that of physical memory. Then, 16g memory needs to be set very large and takes up a lot of disk space. But it didn't work. 2. Because 16g memory is enough for most ordinary users, there is no need for virtual memory at all. It's only a waste if it's so big. 3. But it can't be shut down either. Because someone has tested, 32g computer, after turning off the virtual memory, will also be out of memory prompt. Because some programs need virtual memory. Therefore, for the sake of compatibility, it is best not to turn off the virtual memory and let the system manage automatically.

7. 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.

8. Domestic does not recognize any so-called currency, at present you say this currency is classified as MLM, do not participate in this investment

9. I use sapphire Hd5670 super frequency Version (1.5 years ago), but also ddr5 generation graphics card, core: video frequency = 850:5000, very fierce, ha ha, but much worse than 6770, the reason for the low model, ha ha.

10. There are two models of gtx1060. Take the fine
graphics gtx1060 as an example, there are two kinds of graphics cards: gtx1060
3G and gtx1060
6G. In addition to the difference in graphics and memory, the core codes of these two kinds of graphics cards are also different. So the performance and computing power are also very different. Other brands, such as Qicaihong, have broken down many models and given several names e to different video memory, frequency or appearance. However, the biggest difference is only one
3G
and one 6G
because this gtx1060 has good computing power, many players have used it to dig virtual currency. It's hard to say how many days to return to the original. For example, when a 6-Piece gtx1060
3G machine was at the top of bitcoin, someone calculated that it could earn about 500 yuan a day, but the price fluctuated at any time, so it was impossible to predict accurately< In a word, there are risks in mining and investment should be cautious.
