1. Generally, it's not recommended to buy mine cards. If you're lucky, it may be OK to use them for half a year. If you're not lucky, it's not impossible to have problems when you buy them home.
some mine cards look good because there's no st in the mine machine, but because the hardware has been overused, all kinds of unstable problems may appear when you play games on the computer, And manufacturers generally do not guarantee the quality of mine cards.
2. I don't know if you use it in a mine or try water. If you're afraid of trouble, it's a brand-name machine to save trouble. You can plug in the power and connect the network cable when you buy it. It's like the one in the galaxy miner, which is more suitable for Xiao
mining
3. The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
4. Bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, 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
advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to
the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)
people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)
I hope I can help you
5. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.
6. Gym mining machine is better. The
blockchain has entered the 3.0 era. The traditional mining machine can no longer meet the needs of mining. The efficiency and safety of gym mining machine are higher.
7. Entity miner, the security is very high
8. Mining depends on luck. The risk is uncertain.
9. The proctivity of grinding machine can be improved by properly increasing the speed of grinding machine, but it can not be one-sided pursuit of high speed grinding. Because of the increase in speed, there will be some problems. For example, the present ball mill is designed and manufactured at a speed lower than the theoretical critical speed. If the critical speed or supercritical speed is used, the grinding effect of the mill will be lost e to centrifugal action; Second, the high speed operation will aggravate the mechanical vibration and parts wear, and greatly rece the service life of the equipment. At the same time, the internal grinding function of the ball mill is destroyed, the ore discharge becomes coarse, and the load of the classifier is increased, so that the proct can not meet the requirements of qualified particle size. Moreover, the consumption of grinding medium and liner increases greatly. Therefore, the working speed is used in most concentrators instead of critical loading.
10. Hello, landlord, this is a very professional question, so we will use a professional answer to tell you:
grinding machine
working speed is his
critical speed
76% - 88%, grinding machine proction efficiency is the largest. Of course, it needs to be adjusted according to your proction needs.
