There will always be harm after computer mining

1. There must be damage. First of all, only a card can be used for mining, and N card is boring for mining.
secondly, the computer needs to be running all the time and can't be turned off for mining, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity

2.

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

3. Mining mainly depends on the graphics card, the damage is also the graphics card. At that time, bitcoin, lightcoin and other crazy time, many people loading machine, a minimum of six 7850 or more graphics card, 24-hour uninterrupted operation, and later devalued a day's electricity charges can not earn, so second-hand graphics card mining card can't buy!!

4. Mining with the graphics card in the computer requires a long-time operation of the computer, and the graphics card needs a lot of calculation. Compared with the normal use of the computer, it will have greater loss, and the service life will be greatly reced. At the same time, long-time operation, the hardware also emits a lot of heat, if the heat dissipation is not good, it will affect all the hardware

5. First of all, whether a blockchain project is MLM or not should be judged from multiple perspectives.
in the process of development, blockchain has gone through three stages
blockchain 1.0. In this stage, it is mainly to realize digital currency, core nodes and front-end tools
the biggest feature of blockchain 2.0 at this stage is that it supports smart contracts, one of the representative procts is Ethereum. In Ethereum, the smart contract is used to develop the contract program, and finally deployed in the blockchain ledger
blockchain 3.0 blockchain goes beyond the scope of digital currency and regards blockchain as a wide range of solutions, which can be combined with other fields by using blockchain technology
however, many domestic blockchain related projects stay in the stage of blockchain 1.0, and one of their basic modes is to publish white papers, issue digital currency and go to the stock exchange, Then in accordance with the market, trading to earn profits
however, there may be some MLM money, air money and so on. What we can do is to take this kind of thing with a rational eye and not to invest blindly

6. There must be damage. If the graphics card is used, it will run with full load and generate a lot of heat. If the quality of the graphics card is poor and the heat dissipation is poor, there is a risk of burning out

7. The harm of Trojan virus can be divided into the following concentration

1. Joke virus is not destructive, but it will cause certain interference to users

2. To control the virus, you will generally control your computer, leaving a back door so that you can enter and leave your computer at will and steal your privacy

3. Number stealing: you can steal your game account< Destructive: directly destroy your computer system and files. Cause the file to be deleted, lost, infected, etc. The plot is very serious

the first and second are usually not infectious. The third and fourth are highly infectious~

8. Iron ore is one of the earth's mineral resources that people exploit, and it is also used more. Excessive exploitation of iron ore will cause the following problems: (1) over exploitation or even full exploitation of iron ore in a certain area will lead to the formation of fault subsidence, subsidence or the entry of groundwater. (2) there will be environmental pollution Now, it is rare that the main iron ore is to be smelted, which will proce waste slag and exhaust gas and pollute the environment
for the whole earth, I don't think it's a big problem. After all, the distribution of iron ore is not concentrated in a certain area of the earth (such as the oil in Western Asia), but only partially changes the natural environment near the surface, which will not have much impact on the earth.
