Second hand dashei mineral machinery trading network

1. At present, the market price of second-hand mining machine is quite different. We need to evaluate the service life and the aging condition of the parts in order to get the result.

2. To buy a second-hand miner, you need to find a previous miner or a big miner. But second hand mining profit is almost impossible, buy is a pile of scrap metal, to be prepared.

3. Mining machine there is a kind of virtual currency called bitcoin on the Internet. There is a mining pool with a lot of data. Then you need to use your computer to calculate the data. Then you will get a certain amount of bitcoin. Then these bitcoins can be converted into cash on some websites. Then these data are quite difficult to calculate. The performance of the machine is very high. This kind of computer is called mining machine. Generally, it has six cores The i7 or 8-core pile driver as a processor has at least four 7870 graphics cards as GPU, and it seems that AMD's graphics card has some advantages. N card's Tesla graphics card is too expensive

4.

Ant mining machine Z11 reference price is 7600, second-hand words may be relatively low, hand is also more difficult. Is specialized in ASIC mining, rated power consumption: 1418w (minimum), 1673w (maximum)

power consumption ratio: 25 ° C ambient temperature: 11.24j/ksol (maximum)
40 ℃ ambient temperature: 11.01j/ksol (minimum), 11.78j/ksol (maximum)

because the current ASIC mining currency is relatively low, so many do IPFs mining. IPFs mining hard disk has high value preservation, low power consumption and low power consumption< br />

5. It's a garbage collector or a miner. If it's a miner, save it. Don't do too much. Now the cost of mining is very high, which is close to or even more than bitcoin. Retail mining has graally withdrawn from the historical stage of bitcoin mining. Now mining relies on low energy consumption and low electricity price. This bitcoin home network has related analysis articles.

6. At present, the central bank does not recognize similar currencies as virtual currencies.
it is recommended not to participate in investment to avoid policy risks leading to losses.

7. The composition and decomposition of forces

because the speed is 0 at this time, the centripetal force is 0, so the decomposition diagram of the force can be drawn, that is, the component force of gravity in the direction of

rope is equal to the tensile force on the rope, but the direction is opposite. According to the angle of the rope,

degree, the component of gravity can be calculated, so the pull of the ball is small

8. First of all, you need to have a + 5 mining FM glove ~
copper mine
Silver Mine
Gold Mine
smelting of real silver mine can increase a lot of proficiency. Once you learn it, you have to go to ah to buy ore smelting for 1 second + 1 point ~ this is the fastest ~ others have to rely on their own mining transition. Generally, there must be 2-5 ore spots in a cave. When you see a cave, you have to drill into it. Don't forget to take the accessories for the acceleration of mount< br /> http://wow.owan.com/0901/m_ 95713980687. HTML
this is all the classic routes of mining.

9. At present, mine accidents generally refer to coal mine fatalities, so it is coal mine workers who are killed in mine accidents, of course, including coal mine management personnel. In 2010, there were four fatalities in my city, each of which was one person. As a result, it happened that every time it was the head of safety supervision section. I graated from the coal school, and my classmates and alumni have also sacrificed in the mine.

10. Second hand hardware is safer to go to physical stores. Although online stores are cheaper, they are really not safe. There are too many routines. Of course, physical stores also have a lot of routines, all of which are face-to-face inspection, so it is difficult to cheat.
