Ant mining machine S9 how much a day to dig

S9 computing power 13.5T, the current network computing power 6.39eh/s, 1e = 1024p, 1p = 1024t, 1t = 1024g, a S9 a day to proce bitcoin is [13.5 / (6.39 * 1024 * 1024)] * 180 ≈ 0.0036btc< br />

2. According to the current total computing power and the current growth rate of total computing power, it will take about 250 days to dig a bitcoin

Ant miner is the first cryptocurrency miner brand in the world with a market share of about 70%. The mining machine is developed by bitmainland and has a patent in mainland China. At the beginning, ant miner had only bitcoin miner. Later, its business expanded to other cryptocurrencies, such as Ethereum, dascoin, Leyte, Monroe, etc

ant mining machine adopts ASIC chip designed by bitcontinental, which is proced by TSMC. All chips are made of BM prefix. Each miner has three to four circuit boards, and there are dozens of chips on the circuit board. Therefore, each miner can only be used to mine one or more cryptocurrencies using the same algorithm

ant mining machine needs special mining software, and can not use third-party software. In addition, because of its high power, the ant miner also needs to be used with a special fire ox

The ant miner is often criticized as monopolizing the cryptocurrency mining instry e to its 70% market share, which goes against the purpose of cryptocurrency decentralization. Because Monroe was worried that the mining machinery would monopolize the mining market, Monroe announced to change the mining algorithm a few days after the launch of Monroe (X3 model) despite the opposition of Monroe community, so that all mining machinery could not be used to mine Monroe. Bitcontinent also encountered the failure of its first proct here

the ant miner will use a lot of electricity and proce a lot of waste heat in the process of operation. This leads to a large amount of electricity being consumed for mining or cooling, causing a lot of social criticism. Too much ant mining machine at the same time also led to fire and power failure, causing social inconvenience

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband

extended data

users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

5. Bitcoin mining machine
mining is definitely the first professional mining machine, many new children's shoes will choose to use graphics card mining, but the graphics card mining is just like using "magic oil" to do a professional thing, but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

6. Because of different brands, the design concepts of procts are different, and each has its own advantages
it is recommended to choose the right mobile phone according to the needs and preferences. Due to the large number of mobile phone models and different application groups, you can visit Samsung website to view popular flagship models and the latest procts.

8. Installation of ant protection board app, only support Android protection board calibration:
1. Unit voltage calibration: by adjusting the "system reference voltage" (about 3.0 by default), slowly increase and decrease the amplitude of 0.001, the unit voltage value can be changed until it is accurate! 2. Total voltage calibration: by adjusting the "total voltage ad value into the actual voltage of the parameters" (default about 3330), slowly adjust the size of this value, you can change the total voltage until accurate! 3. Current calibration: by adjusting the "current sensor range", slowly adjust the value, you can change the current until it is accurate
note: please do not change the item of "power starting current" in parameter setting, too large may lead to MOS tube burning and discharging!!!

9. It should be universal
