The latest bitcoin mining machine selection tutorial RHY teaches you how to pick the miner

The profit of bitcoin mining machine mining has been rising with the price of the currency, which has been sought after by more and more investors. Miners have entered the field for mining. However, for the bitcoin mining machine that mines, many miners are ignorant. The performance of the coin mining machine is directly linked to the mining revenue. Nowadays, there are many kinds of mining machine brands on the market. In the face of mining machines with different performances, how to judge the overall performance of the mining machine? What are the excavators? Which of the current mainstream Bitcoin mining machines is better at mining revenue? Most miners don't know about it. For this, the RHY mine below analyzes the bitcoin mining machine to show you how to choose a better bitcoin mining machine.

(1) First understand the bitcoin mining machine, we must know the principle:

1. Four conditions for mining:

(1) Mining machine: professional mining equipment, capable of providing powerful computing power to obtain a certain amount of bitcoin;

(2) Supporting facilities: power supply, network connection, heat dissipation equipment and external environment with appropriate temperature and humidity;

(3) Mining software: the mining machine needs to download and configure special mining software;

(4) Mine pool service: The mine machine needs to be set up to access the mine pool, and the mining revenue is obtained according to the mine pool distribution mode.

2. Factors affecting mining revenue

1. Calculation: The higher the computing power, the more times the hash collision occurs per second. The higher the probability of solving the answer, the more Bitcoin will be dug.

2. Power consumption: The lower the power consumption, the lower the electricity cost, the lower the cost of mining, the higher the profit;

3. Fortunate value: If you choose the PPLNS income distribution model of the mining pool, then the probability of obtaining the income is also related to the lucky value. There is a certain probability factor in the mining pool explosion (production and confirmation of a block), the probability factor is called lucky. Value; when the lucky value is high, the income of the mining pool will increase, and vice versa. This factor can be ignored when selecting a PPS+revenue allocation model.

(2) To select Bitcoin mining machines, we need to pay attention to:

1. The higher the power, the better the mining machine is.

In theory, the faster the mining speed, the more likely it is to find an effective hash. The higher the probability of “explosion”, the more likely the miners will get a high bitcoin reward. This has led many people to use the level of computing power as the only criterion for selecting bitcoin mining machines.

As we all know, the power of the mining machine is determined by the performance of the chip. The iteration of the chip can greatly increase the power of the mining machine. But after all, chips are highly sophisticated equipment, and it is not so easy to update. If the chip process is not effectively improved, the method of increasing the power of the mining machine is often to increase the number of chips on the single-block power board, but this will reduce the performance of the machine.

Professional mining engineer pointed out that assuming that there are too many calculation boards for a single mining machine, the size of the mining machine will be too large. Such a mining machine is more difficult to repair than it is, and it is essentially the same as stacking multiple mining machines. And if there are too many chips on a single block of computing power, it will cause the temperature to be too high, causing irreversible damage to the mining machine directly.

The computing power of the Bitcoin mining machine should be controlled within a certain range to optimize the overall performance.

Summary: If the technical level of a certain Bitcoin mining machine is not significantly improved, but the mining machine's computing power is leaps and bounds, the performance of the mining machine will be greatly reduced.

2. Determine whether the purchased bitcoin mining machine is cost-effective by price per T

Previously, a company announced its mining machine with a power of 5120T. The price of the whole machine was about RMB 41,4368.6293. Suppose you use this money to buy a domestic 14T mining machine, you can buy 410 units, equivalent to 5740T computing power.

Therefore, some of the most expensive machines on the market are very attractive in publicity, but the price is not particularly affordable. Sometimes it is more cost-effective to buy multiple small-sized mining machines.

Summary: When judging whether a mining machine price is reasonable, you can refer to the market price of each T calculation power and compare it horizontally.

3. Calculate the profit and return period of a single mining machine by calculating the currency and electricity bill.

Bitcoin's algorithm determines that the entire network can produce about 1,800 bitcoins per day, and the total network power is now about 53.23EH/s. According to the calculation formula 1E=1000P, 1P=1000T, the theoretical yield of bitcoin of 1T computing power is about 0.00003394BTC.

Take the current fire ant mining machine S17 as an example, the market price is about 2180.1276 US dollars, the calculation power is 53T, we calculate the electricity cost 0.04331 US dollars, the ant S17 daily currency amount is 0.00179882BTC, to the current currency price 9529.0347 US dollars Calculated, the ant mining machine S17 produces a daily income of $ 17.1417. The actual power consumption of the ant mining machine S17 is 2800W, and the electricity cost per kilowatt is about 0.04331 US dollars. The electricity cost per day is about 2.9107 US dollars, so the mining cost per day is about 2.9107 US dollars. In this way, the daily mining revenue is 14.23 US dollars, returning to the current cycle 154 days or so (note: this time the number of days does not consider the difficulty of economic growth and currency price fluctuations). Since the mining days of the mining machine are basically the same, the net profit of the mining machine can be seen by comparing the daily profit.

Summary: The net benefit of a Bitcoin miner can be assessed by calculating the daily mining revenue and return period.

4. Determine the input-output ratio of mining operation through the calculation of power per watt

A qualified miner, in addition to being able to choose a high-yield mining machine, should be able to find cheap power resources. The biggest cost of mining is electricity. Therefore, every power we invest in should be maximized.

The mining machines on the market will have a list of specifications, showing a series of parameters such as product power calculation, wall power consumption, size and so on. However, there is an indicator that it rarely appears in the parameter display of major mining machines, because it is like a “mirror mirror”, which directly exposes the power conversion rate of the mining machine, and makes some so-called “high computing power” “electricity mice”. Nowhere to shape. It is - every watt of power.

Simply put, this data means how much revenue per kWh consumed by your miner can bring you. The formula is G/W.

For example, a mainstream miner has a computing power of 13.5T and a power consumption of 1350W, which is calculated to be 10G/W per watt. Another brand of mining machine with a power of 12T seems to be no worse than the former in terms of computing power. However, since the power consumption reaches 2100W, the power per watt is only 5.85G/W, which is only half of the former. .

Summary: Calculate the power per watt, you can see how much mining income per watt of energy input, to prevent being blinded by some mining machine parameters. Just as you choose a smartphone now, the high parameters are not necessarily good. Under this, the vast miners understand, if you want to know more about the mining machine, you can choose the mining machine suitable for everyone in the RHY mining machine mall. The RHY mine has more cloud computing power, mining machine rental and mining machine hosting. The mine service provides an excavation electricity fee of 0.02743 USD per kWh, allowing the miners to obtain more affordable mining and mining experience than the domestic flood season, and enjoy the mining bonus period with the price increase.
