Disadvantages of mining

1. At present, the most popular way of bitcoin trading is contract trading. According to the rise and fall of the price, it is far better to obtain income than the traditional mining and direct trading. After all, there is no need to really hold virtual currency, just need to judge whether the price is up or down, which is very suitable for the existing investors, simple and convenient

2. I guess what you see is bitcoin
this is a kind of virtual currency, which fluctuates
some people run the so-called mining program to "dig" bitcoin in their spare time and sell it when they get it. Some of them operate as companies and invest a lot of manpower and material resources in mining. It's hard to tell the profit and loss
bitcoin is not as easy to get as it used to be.

3.

It will accelerate the aging of graphics card

in order to make money, the graphics card works continuously for 7x24 hours and runs at full load. Some people will overclock the graphics card in order to earn more money. The general home game graphics card is not designed for this kind of use environment at all. Long time full load operation will lead to accelerated aging of the graphics card, Generally, the life of the graphics card used for half a year of mining is longer than that of the normal use of the players for three years, so now the major brands have made strict restrictions on the quality assurance of the cards

principles of computer Mining:

starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word of a banknote, you will have the banknote

and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

4. The main problem is the life span

assume the same good environment

a 24-hour full load / high temperature operation

one is standby or not running
then the life of mine card is much lower than that of normal graphics card.

5.

Mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

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

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

6. In short, it's a computing software. It doesn't radiate much (it's also radiated by your computer). The main thing is to eat memory and CPU. It's useless for ordinary families, especially those who don't understand it. On the contrary, it will affect the use and life of the computer. Since it's installed and unloaded by friends, it's good.

7. It's impossible. It's impossible. If I don't do it well, let others take it

1、 What is the harm of open-pit copper mining to the environment: open pit mines are easy to cause water pollution, geological disasters, solid waste pollution, air pollution and water environment pollution

treatment and protection methods: develop new energy, rece mining, reasonable mining

Secondly, the loose surface will cause soil erosion; thirdly, it will cause soil acidification. Because coal contains a lot of sulfur, the mining of coal will cause a lot of sulfur to fuse into the water, and then cause soil acidification, It will cause debris flow and landslide

treatment and protection methods: develop new energy, rece mining, reasonable mining

Thirdly, what harm does iron mining do to the environment: soil erosion, land subsidence caused by mines, destruction of biodiversity and pollution of groundwater caused by waste water containing chemicals in mining process

treatment and protection methods: develop new energy, rece mining and exploit reasonably

1. What is water pollution

when the pollutants entering the water body exceed the environmental capacity or self purification capacity of the water body, the water quality will deteriorate, thus destroying the original value and function of the water body, which is called water pollution. There are two reasons for water pollution: one is natural, the other is man-made. The special geological conditions make a large number of chemical elements enrich, natural plants proce some harmful substances when they decay, and rainwater falls to the ground and flows into the water body with various substances, all of which belong to natural pollution

9. Peeling and skinning depends on the occupation. According to principle, Xiaode, DZ, LR and SM learn better. Now all the good things in manufacturing instry are manufacturing binding, and skinning will surely have a fire one day (the same as forging in manufacturing instry is an example, how fierce the three-stage hammer is!), But it's hard to say when. Leather armor can also earn extra money, and peeling is very easy to practice, unlike mining can drive people crazy
Shuangcai makes money quickly. It's great to listen to the sound of gold splashing. It's better to suggest DZ, FS (SS, LR is also OK). It goes without saying that DZ is a thief! FS has a lot of convenient skills, such as transmission, invisibility, flicker, slow down... But if you are just starting to play wow, it is not recommended to double mining, because you don't know the use of many materials, and it's also very important to be familiar with the map, and even if PVP is serious, no one can guarantee that you will be killed when mining! Of course, it's a good choice for ashes and PvP talents Double mining can be mining and grass, mining and skinning, the latter is more convenient. Suggest next gather plug-in)
if you want to be a battlefield master, mining engineering is a very good choice, any profession can, like now mage thieves play so much, the advantages are very obvious, the frost grenade is disgusting, it's just a remote ice ring, it's really playing dead (I'm not playing engineering, so I don't have much experience to tell you, But there are a lot of FS videos on the Internet, which are really great). The disadvantages are also very obvious. It's hard to make decent things without large maintenance. Playing engineering is a bit like killing you with money...
my personal opinion is for reference only!
