Air cooling in mining

1. The price of bitcoin has gone up abruptly, and the old miners who left the mine have begun to return. Many new people have also poured into the mining instry. However, the price has gone up, and the difficulty of mining bitcoin is also rising. How can we make money from mining now
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.

2. Yes, but I suggest you don't do it unless you know the technology and have a more accurate forecast of the growth of computing power in the whole network. Now the leasing business of lightcoin miner is almost suspended, because the miner's update speed is too fast. But now all the major mining machinery manufacturers have launched the power leasing and power financing business, which means that you can buy the power of the platform, and the platform is responsible for the operation and management, and charges the handling charges. The benefit is yours. Power financing means that you can buy the power to trade or other benefits.

3. It depends on the benefits of both. If you often work with the replica, you can consider doing engineering and mining, because the replica equipment is not much worse than the equipment made by leather making, and it's just DKP. For leather making, you have to make your own materials, so it takes a lot of G, and the good drawings are all dropped from the replica, so it's better to take the replica equipment directly. Unless you want to make the leather making drawings for the hunters in SW, but the drawings are expensive. Unless you brush the monsters yourself and have good luck, and you have the drawings you want to make, you can consider making the leather making equipment on the premise that you have complete materials, but I think it's worth making clothes. If you have more activities with the ngeon, it's better to install the ngeon. Although the drawing of SW is 154, the egghand is 164, and the clothing and armor of Muru is 151. In addition, the current version of Hunter begins to build armor, so unless you want to be the leather hand of the thief (you don't have to do it if you have egghand). So I think it's good for you to build a project. As long as you often follow the activities, you don't have to worry about the equipment. It depends on how you decide. I hope it will help you.
