Is mining machine harmful to human body when installed at home
Yes, but it can't compare with others. The money g can't fill the electricity hole. Home computer configuration is low, graphics card computing power can not keep up, mining machine is generally equipped with server power work. Now mining mainly depends on the graphics card (GPU), ordinary home computer, may dig hundreds of years to dig a coin
now mining has entered the era of specialization and clustering. Without professional mining machines, there is no profit (because you have the cost of electricity). How can you compete with tens of thousands of other machines. If you really want to do mining, Jianye will buy a special miner to join in the large-scale mining pool.
mining is to use mining equipment to calculate a large number of mathematical problems, confirm network transactions, and ensure the operation and safety of the whole network system. As a reward system, the miners will be given unequal bitcoin rewards
the operation of bitcoin miner consumes a lot of power and proces noise. When other people use graphics card mining, I need a lot of refrigeration equipment, burn many graphics cards, commonly known as burning graphics card. Even if bitcoin ASIC mining machine is used, it will also proce noise, so some people even think of using the heat generated by mining machine to warm up in winter. Many well-known big miners and data centers in the world have set up their mines in some countries near the Arctic, where the weather is cold, which can save a lot of refrigeration costs.
my view of bitcoin is that it is a very risky investment. Some scholars have pointed out that bitcoin is halved every four years, which was originally designed by Nakamoto. Moreover, Nakamoto has also designed the total amount of bitcoin, which has prevented inflation to a certain extent. However, it is precisely because the bitcoin reward of blockchain is halved every four years, so in 2016, after the price of bitcoin plummeted, it quickly recovered and reached its peak. Therefore, it can be said that this design of Nakamoto Tsung actually ensured that the value of bitcoin would not decline too much to a certain extent. Bitcoin has entered a crazy state since 2017. The price of a bitcoin once rose to more than US $20000, which caused many speculators to rush in. Bitcoin, based on blockchain technology, entered an oscillation period of decline at the end of 17. It once dropped to about US $5000 and rose to more than US $10000 after the Spring Festival. It can be seen that every time the price of bitcoin falls, there will always be a lot of money coming in to boost the price rise, and there will always be the shadow of operators behind
why is bitcoin so popular recently! Let's talk about my views:
first, there are a lot of myths about sudden wealth.
for example, the founder of reborn coin has become the richest man in the blockchain. Some people are worth hundreds of millions in a short time relying on bitcoin. In addition, people like baoerye are telling stories everywhere, from beef sellers to Rolls Royce mirage who can buy limited edition, Many people yearn for it
{rrrrrrr}
4. The title of bitcoin blockchain
the blockchain technology behind bitcoin claims to replace all centralized organizations, which is obviously a utopian plot, but utopia is often beautiful, although it can not be realized, but everyone goes for it
I think that bitcoin is actually a data logic in the guise of blockchain, and its existence foundation is very fragile. Once there is a problem, it will lose everything. Therefore, the risk of the currency market is too great, so we must be cautious if we want to enter the currency market
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~
as for how far to see the village, if it's near, is there any abnormal children in the village before Mo problem
in general, there is nothing wrong
molybdenum has certain damage to the body, such as conjunctivitis, general fatigue, dizziness, chest tightness and other symptoms after long-term exposure to molybdenum
Guidance:
give the following suggestions: 1. Wear protective clothing and wear protective glasses at work. 2. Pay attention to skin cleaning and hygiene.
so don't worry, it's OK for you to sleep with that ore. I used to pile a lot of tungsten and molybdenum ore in my office, and it's still alive ~
good health.
1. The electromagnetic radiation generated by wireless routing is very weak, which is not much different from that of radio equipment, and it is much smaller than that of mobile phone after connecting
2. However, wireless routing works continuously (i.e. continuous radiation). Compared with the non long time continuous radiation of mobile phones, the total radiation of wireless routing to human body will be higher
experts suggest:
1. In order to rece the radiation as much as possible, wireless routes should be placed far away from people, especially in bedrooms. The elderly, children and pregnant women should avoid contacting wireless routes and other devices for a long time, and the power should be turned off before going to bed at night
2. Pay attention to avoid wireless procts being too close to audio, TV and other electronic equipment to prevent mutual interference and other radiation. As long as you keep a long distance, avoid the cumulative effect of living in the wireless network environment for a long time, and develop good use habits, there is basically no problem.
Hello, strong Nd-Fe-B magnet has no adverse effect on the body, but we should pay attention to safety and avoid eating by mistake
first, strong magnet, the professional name should be NdFeB strong magnet. Of course, if the volume is too large, it's hard to separate them. Generally, it needs to be rubbed open with professional wooden scissors. If you have to separate with your hands, be careful< Second, NdFeB magnets are permanent magnets, which will not fade e to time. There are two points that can be changed,
1.
the temperature exceeds the range of 80-180 (e to different properties)<
2
thirdly, magnets are basically harmless to the human body. There is no big problem except that they are easy to pinch hands. At that time, you should pay attention to things like bank cards and deposit cards, and be careful that they are magnetized.
