USB bitcoin machine

1.

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

2. This depends on what configuration of bitcoin mining machine you buy. Take Avalon mining machine as an example, avalon2
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.

3.

Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension

after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card

CPU is not very important. But not lower than i5< br />

4. This depends on the brand and computing power of the Miner you buy. According to Avalon, the mainstream miner in the market at present:

avalon2 single-mode group
(chip frequency 1500mh / s) ￥ 488 100 g ￥ 4.9 / g 340W ￥ 2.04 / g 0.0037 BTC
￥ 14.11 51 days
avalon3 single-mode group
(chip frequency 500mh / s) ￥ 1, 988 290 g ￥ 6.9/g 342 w ￥ 0.71/g 0.0108 BTC
￥ 40.93 113 days
avalon3
(chip frequency 450mh / s) ￥ 7866 800 g ￥ 9.8/g 822 w ￥ 0.62/g 0.0299 BTC
￥ 112.91 999 days

5. It's hard to say. It depends on the specific equipment you buy. With advanced equipment and high computing power, the price is naturally high. Of course, if you buy a obsolete bitcoin miner, it's much cheaper

if you haven't played bitcoin or mined before, it's recommended not to buy a miner to mine bitcoin. At present, the profit margin of mining is very low, and retail investors have graally withdrawn from the historical stage of mining. Mining is mainly some large mines, which are deployed in some remote provinces with low electricity price

of course, with free electricity, mining is also possible. If you don't know, you can trust me.

6. I suggest you don't go. I'm Lenovo g480 computer. I g for a week and got 0. 000034 bitcoins are not enough for electricity charges. If you want to dig them, you can dig them with professional graphics card machines. Because of different computing methods, it is efficient to dig them with graphics cards

7. I don't quite understand what you said, but I think what you said should be 1000g, which is 1t computing power. Here is the basic information of several mainstream mining machines, For reference only:

avalon2 single mode group

it is not recommended to mine now, You can go to bitcoin home to learn about the latest bitcoin news and consider it carefully!

8. Washing water is usually provided by many kinds of anionic polyacrylamide and common polyaluminum chloride i83398zz352. The price of polyacrylamide and polyaluminum chloride is relatively low

9. Instry 2 is a very fun mod, here I will introce how to use the washing machine! Hope to help you<
synthesis of ore washing machine

1
12 iron plates
iron plates can be obtained by [metal forming machine] or hammer + iron ingot

2
two iron barrels
three iron ingots are synthesized in the worktable in Baicheng V shape

3
basic machine shell
this shell is synthesized by 8 fast iron plates<

4
two electric motors
use coil + iron ingot + tin shell to synthesize electric motor (the arrangement is shown in the figure below)
please refer to the following experience for specific synthesis method<

5
one circuit board
red stone + insulated copper wire + iron board
synthesize at least one circuit board

6
finally, put the above parts according to the following figure
to get the use of [ore washing machine]

end
ore washing machine

to make a 3x3x3 sump
the ore washer needs water! So let's make an infinite pool first
three grids deep, three grids long and three grids wide
finally fill up with water

synthesize a pump
to continuously pump water to the ore washing machine

this pump also needs a [fluid ejection upgrade]
it can output the water extracted from the pump upward
Yes! After putting the pump into the water, the washer will be put on top of the pump

put the pump at the bottom of the water (any position is allowed)
right click the pump and put the [fluid pop-up upgrade] into the pump, as shown in the following figure

connect the [ore washing machine] above the pump or connect the [ore washing machine] through the [XX fluid pipeline]
pay attention to power on the pump

finally! According to the figure below, power on the washing machine, and you can wash the ore
the ore washing machine is used to crush XX ore after crushing by [pulverizer]
how to realize automatic ore washing? Please refer to the following experience!
