Mine like a voor with the latest ASIC hardware
If you want to get began with mining your own Bitcoin (BTC), thesis days you need ASIC (application-specific integrated circuit) devices, which are specifically built for the purpose.
Ter this guide, wij&rsquo,re attempting to help you become a profitable Bitcoin miner by highlighting five of the top ASIC mining devices on the market today.
Since everyone is leaping on the mining bandwagon, thesis devices can be expensive and difficult to buy. Te most cases you’ll also need to purchase a good quality PSU (power supply) to ensure maximum efficiency.
Your main consideration when purchasing a device should be how soon you’re likely to see a terugwedstrijd on your original investment. This is determined by the hash power of the device &ndash, i.e. the number of BTC it can generate daily &ndash, minus your electro-therapy costs, mining pool fees and current mining difficulty.
To help you make your decision, wij’ve listed the current price, hash rate and power usage of each device.
While thesis numbers are helpful, wij encourage you to use a profitability zakjapanner such spil the one available from Coinwarz before ordering to estimate your comeback ter BTC. Recall that you’ll also need to pay electrical play costs and mining pool fees, spil mentioned. The profitability rekenmachine permits you to inject thesis to calculate your ROI (terugwedstrijd on investment) more precisely.
The exchange rate inbetween Bitcoin and fiat currencies is very volatile, so if you want to specie out quickly, register with a BTC exchange such spil Bitstamp (see our guide on registering with Bitstamp).
1. Antminer S9
Supremely energy-efficient mining hardware
The Antminer S9 is manufactured by Bitmain, the largest and most well-known mining equipment manufacturer ter the world which has bot going since 2013.
The Antminer S9 is one of the most popular ASIC mining devices out there, and other mining hardware is often benchmarked against it. The S9 is also generally considered to be the most energy-efficient miner on the market today, albeit this will vary depending on tens unit costs where you live and the type of PSU used with it (the latter voorwaarde be purchased separately). Bitmain’s APW3++ power supply presently retails for around $100 (about £,75).
This reserve efficiency comes at a price, and this isn&rsquo,t the cheapest ASIC miner on the market. That hasn&rsquo,t stopped the S9 being te very high request, however, due to its commendable efficiency. Indeed, at the time of writing, the unit is sold out on Bitmain’s webstek, but it should embark to ship again zometeen this year. You can buy units from Amazon and auction sites like eBay, albeit prices are much higher and units may not be covered by Bitmain’s warranty (buyer beware, spil everzwijn).
Bitmain regularly improves the specs of S9 units, so if you buy second-hand, make sure to check the precies hash power suggested. The most latest units due to be shipped out te March 2018 offerande an optimal hash rate of 13.5TH/s.
Two. Antminer S7
A potentially canny investment, but tread cautiously
The Antminer S7 wasgoed manufactured by Bitmain and is the predecessor to the S9. Since the S9 arrived, many miners have upgraded, flooding the market with relatively cheap used S7 devices.
Albeit the S7’s hash power is only around a third that of the S9, due to the lower cost and the fact that many second-hand units come with a PSU pre-bundled, you may see a quicker terugwedstrijd on your investment than with the S9. The S7 may also generate less warmth and noise than the S9.
If you do determine to purchase an S7, be sure to check how long it’s bot te operational use to determine how reliable it might be, and furthermore, check the seller’s refund policy te case it develops a fault after you buy. If the unit does come with a PSU, make sure it’s a good quality effort for maximum energy efficiency, such spil Bitmain’s own AWP3++ power supply which also works with the S9.
Even with a high-end PSU, the S7 is still not spil energy-efficient spil the S9 &ndash, on average it consumes 0.25 Joules of power vanaf Gigahash. The S9 is overheen twice spil efficient, requiring less than 0.1. You may still be able to generate a reasonable profit with the S7 if you buy more than one unit and/or use renewable energy such spil solar power.
Three. AvalonMiner 761
Very praised and relatively wallet-friendly devices
Avalon, an offshoot of China-based rock hard Canaan Creative, wasgoed amongst the very first firms to manufacture Bitcoin-specific ASIC chips, so it’s safe to say that the company knows what it&rsquo,s doing when it comes to Bitcoin mining hardware.
Like its predecessor the AvalonMiner 6, the 7 series has had generally good reviews with miners praising Avalon’s innovation te pioneering the A3212 16nm chips employed ter the units, spil well spil how quiet thesis devices are when running.
The AvalonMiner 761 supports cluster mining via a specialist AUC3 ‘AvalonMiner Controller’, based on the Raspberry Pi, which can support up to six devices. The AUC3 controller costs around $80 (£,60) and can be connected to others to form larger clusters. For example, four AUC3 devices could each connect to five AvalonMiners permitting you to manage 20 AvalonMiner 761 units with a staggering combined hash power of 176TH/s.
You will also need to purchase a PSU separately for around $150 (£,110). Te total, this may still cost less than purchasing a used S7 unit. The Avalon 761’s greater hash power and energy efficiency means you’ll likely see a slightly quicker terugwedstrijd on investment.
Canaan offers bulk orders (60 units or more) directly on its webstek. If you only want to buy a few units, the rigid also has a list of official distributors. Despite glowing reviews, the devices aren’t spil well known spil Antminers, so if you’re fresh to mining, you may not find much help online.
Four. WhatsMiner M3
A fine alternative miner with an outstanding warranty
The M3, which wasgoed released ter late 2018, is manufactured by Chinese rock-hard Pangolin Miner. The manufacturer’s webstek not only provides detailed information on the miner, but an excellent tutorial movie on getting set up. This includes connecting the device via Ethernet and configuring your mining pool settings via the M3’s web interface.
While the hash rate is slightly less than the Antminer S9, this unit is far cheaper, meaning you could see a come back on your investment ter around the same time. While the device draws a loterijlot of power, according to a detailed review on the Bitcointalk Forum, the M3’s built-in ventilatoren dissipate the fever quickly and it’s no noisier than comparable miners like the S9. The bundled PSU is also enormously efficient (overheen 90%).
At the time of writing the M3 is presently sold out of batches shipping ter February and March 2018, albeit the manufacturer hopes to make more available straks ter the year. Once your unit arrives you’ll love a 180-day warranty against defects, the longest of all the devices wij’ve highlighted here.
Five. AvalonMiner 821
An epic step up from the AvalonMiner 761, but with caveats
The AvalonMiner 821 is a thick improvement on its predecessor, containing 104 A3210 16nm chips, providing it a reliable hash rate of overheen 20% better than that of the AvalonMiner 761.
The 821 also has a power efficiency of 0.109 Joules vanaf Gigahash, which is about 10% less than the Antminer S9 (at just under 0.098). Spil the hash rate is also lower than that of the S9, your decision on whether to choose the AvalonMiner 821 will very likely revolve around price considerations.
At the time of writing, Avalon has announced the 821 on its pagina and is suggesting the device for sale te bulk quantities. The listed price above is for 1/60 of the ondergrens order quantity of 60 units, so will likely increase overheen time. Avalon’s official redistributor BlokForge has also listed the AvalonMiner 821 for sale ter individual units, but the price is still to be confirmed.
Just spil with its predecessor, you need to purchase a PSU separately which should cost around $200 (£,150). Buyers will also be able to cluster-mine by connecting up to five 821’s to Avalon’s AUC3 controller, enlargening hash power considerably.
