Ethereum mining has become a sweet pastry, how should ordinary people enter the market?
"In the article, we introduced three ways for ordinary people to enter the Ethereum graphics card mining market: cloud computing power, joint mining, and purchasing mining machines to host them in the mine.
Today, let's talk about the hosting of graphics card mining machines, especially the matters that need to be paid attention to when choosing a mine.

Safety and reliability always come first
Whether it is an ASIC mining machine for mining Bitcoin or a graphics card mining machine for mining Ethereum, safety and reliability are always the first priority when looking for a hosted mine.
Safety refers to the scientific site selection of the mine and the safety measures in place. Affected by torrential rains during the flood season, natural disasters such as floods and mudslides occur in Sichuan every year, and many small mines are built on open land next to dams and hydropower stations, and the mines are washed away by floods or submerged by water, etc. Accidents are not uncommon. In the unfortunate event, ordinary miners are in a weak position, and the possibility of claiming compensation at the price of the mine is very small.

In addition, safety measures in the mine must also be in place. The mine is full of various types of wires, which are very easy to cause fires. Accidents such as explosions of high-voltage transformers, explosions of power lines of third-party mining machines, and short circuits caused by aging lines are not uncommon. If safety protection measures are not in place, the entire factory building may be burned down. Last year, a fire broke out in a mine in Xinjiang, burning down a factory building and destroying thousands of mining machines.
Reliable means operating with integrity. In Sichuan, there are countless large and small mines, and this year there are signs of "supply exceeding demand". In some WeChat activity groups, we often see people posting "XXX mines, and XXX aircraft slots, electricity prices Beautiful, welcome to flirt" and other attractive advertisements. If you think of their "cheap electricity bills", you are likely to fall into the pit. Behaviors such as running away from the mine, refusing to relocate the managed mining machines, maliciously sitting on the ground to raise prices, and stealing the computing power of the mining machines have occurred from time to time.
So, here comes the question, how can ordinary people find safe and reliable hosting mines?
1. The first choice is to know the owner of the mine, or the mine recommended by a trustworthy friend, because they are acquaintances, and they are relatively more knowledgeable.
2. Between old mines and new mines, ordinary people recommend choosing old mines, because new mines need a lot of adjustments, and old mines have been in operation for a long time and have more practical experience in dealing with emergencies. There are fewer things to worry about when collaborating.
3. Prioritize the selection of mines with large scale and high load. The scale represents the strength of the mine. The larger the scale, the more capital investment in the construction of the mine, the higher the sunk cost, and the lower the possibility of the mine owner running away; the mine with a high load has more room for maneuvering, and more Stablize.
4. Prioritize the selection of mines with good market reputation and no black history.

Stability of electricity is crucial
After screening out safe and reliable hosting mines, we will next investigate the power stability of the hosting mines.
At present, the electricity cost of Ethereum graphics card mining machines generally accounts for 10% to 20%, so compared with Bitcoin ASIC mining machines, Ethereum graphics card mining machines are not so sensitive to electricity prices. For example, the latest generation of Bitcoin ASIC mining machine - Antminer S19-95T mining machine, based on the current currency price of ¥70440 and the electricity price of ¥0.23 during the wet season, the daily electricity bill accounts for 38%; the Ethereum graphics card Mining machine 5700XT 8 cards, based on the current currency price of ¥2221 and the electricity price of ¥0.38, the daily electricity bill accounts for 16%.

Here is a special explanation of the electricity price. The size of the Ethereum graphics card mining machine is relatively large, but it consumes less power. For mines that rely on the difference in electricity costs to make profits, they will naturally charge higher electricity prices for the graphics card mining machine. Therefore, in the above example, the electricity cost of the graphics card mining machine is calculated based on the market price of ¥0.38, which is much higher than the market price of ¥0.23 for the ASIC mining machine in the wet season, but even so, the electricity cost of the Ethereum graphics card mining machine accounts for The ratio is still much smaller than the Bitcoin ASIC mining machine.

Operation and maintenance capabilities are directly related to the revenue of graphics card mining machines. The software and hardware of graphics card mining machines are complex, and the maintenance is more difficult. The general Bitcoin ASIC mining machine operation and maintenance team cannot do a good job in the operation and maintenance of graphics card mining machines in a short period of time. If the graphics card mining machine is damaged, and there is no professional graphics card mining machine maintenance personnel in the mine, the mining machine will be sent to the maintenance point for repair, and it will take ten days and a half a month to go back and forth, which is not a small loss for the miners.
other considerations
In addition, the computing power of the graphics card mining machine is not as stable as that of the Bitcoin ASIC mining machine, and it takes longer to debug the mining machine. There are many mining software for Ethereum graphics card mining machines on the market. Different mining software has different stability and pumping ratio. How to choose the most suitable and cost-effective mining software depends on the experience of the operation and maintenance team.

When choosing a managed mine for a graphics card mining machine, in addition to examining whether the mine is safe and reliable, power stability, and the operation and maintenance capabilities of the graphics card mining machine, there are other considerations:
summary
1. Does the mine have a dedicated graphics card mining machine? The graphics card mining machine is too large, and the general ASIC mining machine shelf is not suitable for the graphics card mining machine.
2. In addition to the most basic temperature and humidity control, has the mine taken anti-dust particles and anti-static measures? In the previous article, we mentioned that the relatively good graphics card mining machine rooms in the industry are basically designed and constructed according to IDC-like specifications.
3. Give priority to mines with convenient transportation. Whether it is to go to the mine to inspect by yourself, or to send the damaged mining machine to the maintenance point for repair, convenient transportation can save a lot of time.
