Bitcoin miner picture hard disk

1.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

2. Yes, as long as it's a high configuration graphics card. Now the mining machine starts with 480. The high configuration can earn some money, but the low configuration can't change the electricity charge. N card's computing power is not enough, a card is much higher. You can register in the mine pool first. If the computing power is too low, it will become an invalid node. If you use a home computer, you'd better use three graphics cards. There is little hope of making money.

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. A lot of people are delisting, tens of thousands
the future is not good
it is recommended not to go to this water mixing station. The machine configuration is basically the best

5.

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

6. 1. Get bitcoin mining Hardware: ASIC chip is the best. 2. Download free bitcoin mining software: cgminer and bfgminer. 3. Can join the bitcoin mine pool: multiple bitcoin diggers work together to solve data problems. 4. Store bitcoin obtained from mining: use hot wallet to store the hash value of bitcoin information.

7. Can be transferred to other disk, or even transferred to the mobile hard disk, portable

with the increasing capacity of bitcoin blockchain data, the client wallet data is installed on Disk C by default. If Disk C is not large enough, you need to find a way to move the data from disk C to other disks
examples are as follows: (Note: close the client first)
1. Find bitcoin's data folder:
XP --- C: & # 92; Documents and Settings\ username\ Application Data\ Bitcoin
vista,win7---C:\ Users\ username\ AppData\ Roaming\ Bitcoin
2. Copy this bitcoin folder to other disk with large space, such as disk D (to avoid operation error, it is recommended to it first and delete disk C after it runs normally, so as to save disk C space)
3. Edit the bitcoin shortcut on the desktop (if there is no shortcut on the desktop, there are two ways: one is to find the installation folder, find "bitcoin QT. Exe", right-click, and select Create Shortcut to cut the shortcut to the desktop or any location; For the second method, if it is a green installation free version, you can find this installation folder, find "bitcoin-qt.exe", right-click and select Create Shortcut to cut the shortcut to the desktop or anywhere.) Right click on the shortcut, select "properties", enter the following in the "target" column and confirm:

& quot; C:\ Program Files\ Bitcoin\ bitcoin-qt.exe" - datadir=D:\ Bitcoin
(red is the target location of the added part)

now, double-click the bitcoin shortcut on the desktop, the client will start, and all data updates will be stored in disk D, and disk C will no longer occupy space. This method can also avoid data re download caused by deleting Disk C e to system re installation, and can also protect wallet files.

8. CP and CV are two different thermodynamic parameters; The former is equal pressure heat capacity and the latter is equal volume heat capacity.
