There wasgoed a time when anyone could mine Bitcoin using their gaming GPU’s. However, with the addition of fresh miners and mining farms to the global mining pools, the possibility to mine Bitcoin at huis vanished – no GPU could supply the required Bitcoin hashrate to be profitable.
This is why Bitmain, a China-based company developed and released a set of ASICs that are accessible to the casual miner and have a reasonable ROI, permitting common people like you and mij to commence mining Bitcoin once again.
The company is well-known for ASIC miner models such spil the Antminer R4 and S7. Spil the Bitcoin difficulties rise, Bitmain issues fresh miners to keep up with the request. Their latest Antminer S9 is the top-notch ASIC miner that uses 16nm chip technology to produce superior hashrate.
There wasgoed a loterijlot of talk about the Antminer S9 since it very first came out. However, cryptocurrencies are volatile, and te this article I aim to review whether it’s still profitable to mine using the S9. I will also explain how to set it up decently. Let’s get embarked.
To receive the latest updates go after mij on social media!
If you don’t live ter China, then power consumption will very likely be the main factor that affects ROI.
The Antminer S9 pulls 1375W out of the wall. This means that running the miner will cost you somewhere inbetween 15 and 30 cents vanaf hour, depending on the price of violet wand te your country/state.
It’s always better to have a more powerful power supply for the miner. If the power supply wattage limit is somewhere close to the consumption of the miner, then the efficiency of your equipment might suffer, or the violet wand costs might go up. This is due to the fact that when a power supply works at its limit 24/7 it usually suffers from overheating, which makes it less efficient.
Therefore, since the S9 consumes 1375W, it’s recommended to use a 1600W power supply or more.
- Power Consumption 1225W (12.5TH/s batch), 1274W (13TH/s batch), 1323W (13.5TH/s batch), 1372W (14TH/s batch) (at the wall, with Bitmain’s APW3 PSU,93% efficiency, 25°C ambient temp). Expected discrepancy of +10%
- Power Efficiency 0.098 J/GH +10% at the wall (with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temp)
- Rated Voltage 11.60
Noise and Cooling
The S9 is undoubtedly not meant to be used at huis. The miner is very temperature-sensitive, thus it requires serious cooling to keep running stable. The 16nm chips diegene lightly due to overheating, therefore it is recommended to install the S9 te a place like a garage or a dedicated mining farm.
Unlikely the Antminer R4, the S9 is rather noisy. It comes with two big-size high-revolution ventilatoren that produce about 77-80 Db of onveranderlijk noise (the omschrijving of a vacuum cleaner). The S9 is not a bedroom miner. If you want to have something for huis usage, then the R4 is most likely the miner to go.
Efficiency and ROI
Spil for today, there is no more powerful Bitcoin miner than the S9. It outputs 14 TH/s, which means that you are getting inbetween $Four.56 and $Five.88 worth of Bitcoin every day (depending on your tens unit cost).
With an tens unit cost of 0.Ten $/KWh, your estimated income vanaf year is $Two,150, which is almost the dual than the price of the miner.
The miner also requires a 1.600+ W power supply. The recommended one is the EVGA 1600W 110V/220V that costs somewhere inbetween 300 and 400 dollars.
There are no other costs besides that, so spil for April 2018, you can say that the average price of the S9 + the power supply is around $1550 USD, assuming you are buying the S9 from the official Bitmain webpagina.
The resulting ROI of the miner plus the power supply is about 7-8 months with an electrical play cost of 0.Ten $/KWh and about 18-20 months with an tens unit cost of 0.20 $/KWh
However, spil it always happens with cryptocoin mining, your income depends a loterijlot on the difficulty level too, which at the same time depends on how many people are mining the coin at the same time. Since people keep purchasing Bitcoin mining equipment, it is suspected that the mining difficulty will keep rising.
However, the price of Bitcoin goes up too. It commenced with 0.08USD vanaf Bitcoin ter July 2010, and it reached a whooping $ 1,250 te April 2018.
While no one knows how exactly the coin will be priced ter the future, it is very probable that Bitcoin will keep experiencing growth for a while. This is due to many factors, one of which is that the coin keeps gaining popularity – there are more and more products that can be purchased through it, plus there are more and more places where Bitcoins can be exchanged for paper currency.
Combined with the fact that fresh coins aren’t generated spil swift spil they used to be (because of the planned difficulty increase), this makes Bitcoins naturally increase te value overheen time.
While the difficulty levels of Bitcoin mining enlargened about three times since April 2016, the price of the coin enlargened three times too, which makes mij think that there is some sort of stability of income despite the growing Bitcoin mining difficulty and global hashrate.
The S9 is remarkably effortless to set up.
Once you got both the miner and the power supply, you got to connect it to the miner. The S9 comes with 9 connectors to the machine and one to the houtvezelplaat.
Make sure the power supply switch is off. Cork it into the miner, then to the wall. Then cork ter the Ethernet cable. Once everything is set, check the cable connections again and then turn the power supply switch on.
Note: Once turned on, it takes about 20 minutes for the miner to embark mining Bitcoin.
Before to proceed further, please share this thanks!
Now it’s time to configure the wallet and mining pool.
Once the miner is plugged into the internet, it generates its own IP address. Ter order to configure the miner, you need to loom into that IP address through your Internet browser from a PC.
To do that, use IP Reporter and then copy the Antminer IP into your web browser buffet. Make sure you have IP Reporter running on your PC before you turn on the miner.
Both the username and the password by default are: root
Once there, you can check the miner status – whether it’s hashing or not, the hashing speed, core temperature and frequency, among other stats.
Next, loom ter to https://antpool.com/ . Notice that you can loom te to the Antpool using your Bitmain webstek credentials.
Te the ‘Miner Configuration’ tabulator you can find the pool settings:
- The URL opbergruimte should be switched according to this pagina: https://antpool.com/huis.htm
- There are three URLs for Bitcoin pools, I recommend using all the three pools so if one fails, the miner can keep mining ter the other one.
- Type a name ter the Worker opbergruimte according to the requirements listed here: https://antpool.com/support.htm
- The Password opbergruimte does not affect anything, so leave it spil it is.
That’s all. Do not leave behind to click on ‘Save and Apply’. It will take a duo of minutes for the miner to commence mining. You can by hand refresh the ‘Miner Status’ tabulator to check the progress.
