Is the miner big

1. No matter what kind of computer, noise is basically a fan problem. If you can't clean up the st on the fan, replace it

2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.

3.

At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip

the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system

extended data:

mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction

any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power

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 are considerable expenses in mining

in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive

4. Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

5. Bitcoin can be understood as a stock, and mining machinery is the employee of the stock. Working for the stock, the stock can be bought and sold as well as transferred as money. When transferring money, users need to pay a service charge, just like bank transfer. The service charge is to pay the wages of the mining machine, so the mining machine has income. After receiving the service charge (BTC), the holder of the mining machine can take it to the exchange to sell it, which is equivalent to making money. Because of the evolution of the market over the years (omitting 10000 words here), now the income is very stable and high, so more and more people are engaged in mining. You can check more on the Internet and search today's miners. There are many articles suitable for Xiao to read.

6. The choice of IPFs miner, expensive is not the key, the key is whether the miner is worth these values
from the aspect of cost performance, Hangzhou Lianzhong
mining machinery is more practical, stable and faster in cost recovery.

7. No radiation, even smaller than some densely populated super cities! It's about power! Electromagnetic wave and electromagnetic radiation are different! Although long-term contact has an impact on the body, standing outside the house basically has no impact!

8. The use of bitcoin is generally related to the quality of mining machines and the growth of computing power of the whole network. Of course, it is also closely related to the electricity price

generally, the service life of mining machines is the whole network, and the relationship between computing power growth is the biggest, because the updating speed of mining machines is amazing. If you can't keep up with the cutting edge of the times, it's very difficult to make profits by using the old mining machines. Naturally, this kind of mining machine will be eliminated, short days, long months, but the general mining machines are rarely used for a year

of course, if the quality of the miner is OK, it will be OK to use it for one or two years

if your electricity price is low or free, then your mining machine will have a long service life, because a large amount of mining consumption is electricity

of course, it is only related to the price of currency. If the price of currency is high and profitable, the life of mining machinery will be delayed, and if the price of currency remains low, the mining machinery will be eliminated quickly.

9. Bitcoin mining machine is also a computer. How much noise does the computer make when it is turned on is equal to its noise
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.

10. Do you want to go to the West Lake Cultural Square or the West Lake
if you go to the West Lake Cultural Square (not beside the West Lake), take subway line 1 to Xianghu. Get off at the West Lake Cultural Square Station and you'll be there
if you go to the West Lake, you can take the subway line 1 in the direction of Xianghu and get off at longxiangqiao station.
