    What is ASIC Bitcoin Miner?

    Since it is now impossible to mine bitcoin with your for-profit computer, you will need specialized hardware called an ASIC.

    Here's what an ASIC miner looks like up close:

    halong digging dragonmint asic

    The Dragonmint 16T Miner.

    Originally, the creator of Bitcoin intended Bitcoin to be mined on CPUs (your laptop or desktop computer). Bitcoin miners discovered they could get more hashing from graphics cards. Graphics cards were then surpassed by ASICs ( application-specific integrated circuits ).

    Think of bitcoin ASICs as specialized bitcoin digging computers, bitcoin mining machines, or "bitcoin generators."

    Nowadays, all serious bitcoin mining is done on dedicated bitcoin mining hardware ASICs, usually in thermally regulated data centers with cheap electricity.

    Don't get confused

    There is bitcoin mining hardware that mines bitcoins.

    There are also hardware wallets for bitcoins like Ledger Nano X which Defend Bitcoins.

    Quick tip

    Mining bitcoins is NOT the best way to get bitcoins. Buying bitcoin is.

    Mining is not the fastest way to get bitcoins.

    Buying bitcoins with a debit card is the fastest way.

    To buy bitcoins in your country, check our country guides:

    ... or visit our exchange finder, if your country is not listed above.

    Check profitability

    You can use our calculator below to check the above hardware. Enter the estimated power cost and hash rate of the miner for an estimate. hash rate:

    Factors of profitability

    The price of bitcoin and the overall network hashrate are the two main factors that will affect your profitability.

    Our calculator is more accurate than most others because ours assumes a 0.4527678% daily increase in network hashrate. This is the average daily increase over the last 6 months.

    Most other calculators do NOT include this metric, making the yield look more profitable than it actually is.

    The price of bitcoin

    Bitcoin mining is thriving industry , but an increase in the price of bitcoin could help offset some of those losses.

    The price of bitcoin has increased by an average of 1.039% per day over the past year. Try messing with the calculator using different prices.

    Know your competition

    It might seem easy to just spin a miner.

    But you have to look at how serious the yield is.

    The video below offers an inside look at one of China's largest mines.

    How to find the best bitcoin miner

    There are several important factors to consider when determining which bitcoin digging ASIC to purchase:

    Hash rate - How many hashes per second can a bitcoin miner make? More hashes cost more, which is why efficiency is crucial.

    Efficiency - You will want to purchase the most efficient bitcoin mining hardware possible. Currently, this is the Halong Mining Dragonmint T1. Since miners use a large amount of electricity, you want to buy one that converts the largest amount of electricity into bitcoins.

    Price - How much is a bitcoin miner worth? Cheap mining hardware will mine fewer bitcoins, so efficiency and power usage are important. The fastest and more efficient mining hardware will cost more.

    Don't try to buy a miner based on price or hashrate alone. The best ASIC miner is the best bitcoin miner. Aim for value.

    QUICK TIP

    You can also mine litecoin with bitcoin mining machines, but it's usually most -better Yes buy litecoin from the exchange.

    Bitcoin miners for sale on eBay or Amazon

    If you're a hobby miner looking to buy some gear for your house, eBay and Amazon have some decent deals on mining hardware.

    Used bitcoin mining hardware for sale

    Both new and used bitcoin mining rigs and ASICs are available on eBay. You may want to purchase used ASIC mining hardware on eBay because you can get better prices.ASIC for sale on Ebay

    eBay's customer protection ensures that you get a working product. Other equipment may be included in your purchase depending on the seller.

    We recommend purchasing the Dragonmint or Antminer S9.

    Hardware profitability

    You can use calculator for profitability at Mining Bitcoins to determine your estimated return value of your mining hardware.

    Reminder

    Be sure to consider your tax liability on the coins you buy or mine. There are some great tax software packages, to make it easier! For example, we have a great guide on how this software works to pays taxes on Coinbase purchases .

    Don't forget to take electricity costs into account. Most mining hardware seems profitable until electricity costs are factored in.

    The best way to determine real profitability is to determine cost your for hash electricity . This will really make or break your operation.

    The most efficient bitcoin miners

    Good bitcoin mining hardware should have a high hashrate. But efficiency is just as important.

    An efficient bitcoin miner means you pay less in electricity costs per hash.

    To improve your efficiency, there are also companies that will let you order hardware into their warehouse and manage the miners for you.

    You can also you're confusing my bitcoins , although these deals are usually scams. Both options are also much less fun than working with the hardware!

    Bitcoin mining hardware companies

    Bitmain - Bitmain makes the AntMiner line of bitcoin miners. Bitmain is headquartered in Beijing, China and also operates a mining pool.

    MicroBT - MicroBT is another Chinese ASIC miner manufacturer based in Shenzhen. Their WhatsMiner series is a major competitor to Bitmain's AntMiner line.

    Canaan - Canaan has launched the first commercial bitcoin ASIC miner. In addition to manufacturing bitcoin mining machines, Canaan also has a suite of blockchain tools and business solutions.

    Equipment for mining bitcoins

    In addition to an ASIC for mining bitcoins, you will also need other equipment for mining bitcoins:

    Power - Bitcoin platforms need dedicated power sources to funnel and use electricity efficiently.

    Cooling fans - Bitcoin's hardware can easily overheat and stop working. Buy enough cooling fans to keep your hardware running.

    Standby generators - You may want generators as a backup in case your main source of electricity goes down.

    You can find bitcoin mining equipment for sale on eBay .

    Bitcoin mining without hardware?

    It is still technically possible to mine bitcoins without special mining hardware.

    You will earn less than a penny a month. Mining bitcoins on your computer will do more damage to your computer and you will not earn a profit.

    So, not worth it unless you're just interested in seeing how the mining process works. It is best to purchase dedicated hardware like the Antminer S19.

    The impact of ASIC on cryptocurrency

    Bitcoin is based on blockchain technology, a decentralized platform that takes power away from the central authority and gives it to the common man. Sensitive information is stored on the blockchain, not in large data centers, and is cryptographically protected. A huge amount of people, known as miners, work together to validate the network, rather than just one person or government.

    In the beginning processors were used to solve the cryptographic hash functions until the miners discovered that GPUs are much better equipped for mining. As the difficulty of blocking increased, miners turned primarily to GPUs.

    Some GPUs are made solely for mining bitcoin.

    Ultimately, the technology was developed solely for yield, known as ASICs or application-specific integrated circuits. Their hash rates are significantly higher than anything GPUs are capable of.

    With stellar performance comes a high price - the best ASIC chips will cost you several thousand dollars each. At their inception, bitcoin blocks were endorsed by the average person using a desktop - once ASICs hit the market, things changed.

    How?

    ASICs have rendered GPUs useless. ASIC developers, including Bitmain, provided early access to large mining cartels, not the common man. Nowadays, most bitcoin mining is done in China, where electricity is cheap.Photos from a Chinese bitcoin mining operation

    Thousands of ASICs dig simultaneously in a mining farm (large warehouse). Obviously most people can't afford just one or two of the ASICs, let alone thousands of them.

    When ASICs came to market, the blockchain validation process became more centralized as more hashing power was consolidated into a handful of mining companies rather than spread across many miners. Unfortunately, bitcoin is no longer as decentralized as it was once intended to be.

    Heir to the throne

    Bitmain Antminer S19 series

    PROFESSIONAL LIST

    • Market leading hashrate up to 115 TH/s and effective at ~30 Joules per TH/s
    • Reasonably priced at $440 new (plus shipping)
    • Popular miner with plenty of manuals and parts available

    AGAINST

    • Not available on Bitmain and hard to find elsewhere
    • Very high power consumption of 3250W
    • Very noisy at 81.4 dB

    Antminer S19 review

    Bitmain's AntMiner S7 has proved so popular since its launch in mid-2015 that it has reached 19 batches of production.

    Now Bitmain has released a new series: the AntMiner S19.

    bitmain antminer s19

    S19 is the newest and best Bitcoin ASIC miner from Bitmain. It comes in three models: the Antminer T19, Antminer S19 and Antminer S19 Pro.

    The T19 outputs 84 TH/s, the S19 95 TH/s, while the S19 Pro boasts up to 110 TH/s of hashing power.

    Prices start at $ 2,118 for the T19 and go up to $ 3,769 for the S19 Pro.

    Power

    S19 Antminers require 3250W power, ±5%.

    The power supply units (PSU) are included in the miners themselves, meaning you won't need separate hardware.

    Energy consumption

    The S19 consumes an average of 3250 watts at room temperature 25^C / 77^F. Naturally, the hotter the environment, the more the fan(s) will consume power to cool the unit.

    I set up

    Setting up S19 through MinerLink's graphical user interface is a simple process, requiring only your dig pool credentials to begin mining.

    Devices will automatically start hashing when powered on, which can be useful in the event of a power outage. S19 connection is via Ethernet only.

    Temperature

    The S19 series miners work best in a temperature range of 5-40 degrees Celsius (40-105 Fahrenheit).

    Keeping the room they are placed in cool and dry will extend the life of these miners. A dry basement is the ideal place.

    Price

    Note: Before you buy Antminer S19, make sure you already have software for yield on Bitcoin and mining pool on Bitcoin .

    The S19 is currently out of stock due to high demand for this latest generation of ASIC miners. You can get used from $ 6,000 to $ 8,500.

    As new models are released and commercial miners upgrade, you can expect the price of the S19 series to drop further.

    Bitcoins / month (profitability)

    Digging difficulties in the Bitcoin network are steadily increasing at a rate of almost 0.5% per day. Combine this with the fact that The Award for the block has been halved in May 2020, and you can see why there is fierce competition among miners to successfully validate blocks and retain profits.

    Let's take a look at how profitably you can expect your mining to use AntMiner S19.

    We will use the most accurate bitcoin mining calculator which takes into account a number of dynamic variables (such as the difficulty of extraction) to give the best idea of projected returns.

    We assume that the average price on electricity per household is 12c per kWh, fee for pool of 2,5% (as charged by AntPool) and award for block from 6,25 BTC per extracted block:

    cost-effectiveness of antminer s19

    As you can see, the S19 is actually a great investment. You'll almost recoup your entire initial investment in less than a year - if you pay full price for the S19 from Bitmain - and you'll easily break your way into the black if you get a discount on the hardware when you buy.

    QUICK TIP

    It may make more sense to invest money in buying bitcoin directly or diverting some of your 401k money into a qualified bitcoin IRA instead of buying mining hardware like S19.

    Antminer S19 Pro review

    Of course, there's the S19's big brother, the S19 Pro!

    The S19 Pro boasts up to 110 TH/s of hashing power.

    Power

    The S19 Pro power supply is the same as the S19 Pro - 3250 W of power, ±5%.

    Energy consumption

    The S19 Pro generates an average of 81.4 dB during operation.

    I set up

    The setup for S19 Pro is the same as S19. The MinerLink GUI is simple and only requires your dig pool credentials.

    Devices will automatically start hashing when powered on, which can be useful in the event of a power outage. Connectivity of the S19 Pro is also via Ethernet only.

    Temperature

    The temperature is the same as S19-between 5-40 degrees Celsius (40-105 Fahrenheit).

    Price

    Note: Before you buy Antminer S19, make sure you already have software for yield on Bitcoin and mining pool on Bitcoin .

    The S19 Pro is also currently out of stock. However, used and pre-owned models can be purchased for between $8,000 and $10,000.

    Bitcoins / month (profitability)

    Using the same assumptions we made for S19, you can expect a nice profit of about $2000 per year.

    antminer s19 for rentability

    Verdict: Is the S19 or S19 Pro right for you?

    The difficulty has been over 300X'd since then, climbing from 0,52 EH/s to the current record of 158.4 EH/s.

    The S19 is one of the most advanced mining units on the market today. Bitmain is consistently on top of the game when it comes to ASIC miners.

    While supplies are limited and the relatively high initial cost can be prohibitive, if you have access to cheap electricity, you really can't do much better than the S19 series.

    The S19 strikes a good balance between power and affordability, while if money is no object, the S19 Pro will throw you a great 115 TH/s.

    Challenger for the AntMiner crown?

    WhatsMiner M30S

    The WhatsMiner M30S+ and M30S++ are the Shenzhen-based MicroBT answer to the Bitmain AntMiner S19 and S19 Pro. The M30S++ emits 112TH/s ± 5%, pushing it a hair above the S19's maximum output.

    Let's look at how they compare.

    Quick tip

    Mining is not the fastest way to get bitcoins. Buying bitcoin is.

    Buying bitcoins with a debit card is the fastest way, but we also recommend using a payment network like Skrill or Interac e-Transfer or use bank transfer like SEPA, when available.

    To purchase bitcoins in your country or state, check out our guides! Some of our most popular ones are listed below!

    ... or visit our exchange finder, if your country is not listed above.

    Overview of Whatsminer M30S+

    WhatsMiner M31S+

    Price and power

    M30S+, whose hashing power of 100 TH/s is comparable to S19. Unfortunately, it's no longer sold on the MicroBT website, so you'll have to get it second hand.

    Bitcoins / month (profitability)

    Let's take a look at how profitable you can expect your mining to be using the WhatsMiner M30S+.

    Again, we'll use our bitcoin mining calculator, which takes into account a number of dynamic variables (such as mining difficulty) to give the best idea of predicted returns.

    We assume that the average price on electricity per household is 12c per kWh and award for block from 6,25 BTC per extracted block:

    whatsminer m30s+ rentability

    Power supply and consumption

    The WhatsMiner M30S+ consumes slightly more power than the AntMiner S19 series and is slightly less efficient at converting electricity into bitcoins.

    It has an efficiency of 34 J/TH ..

    The M30S+ generates approximately 83.0 dB of noise during operation.

    Temperature

    WhatsMiner M30S+ works best between -5 and 35 degrees Celsius (23-95 Fahrenheit). This is a wider range than the AntMiner S19 series and the lower temperatures it can operate at means you may see slightly improved performance.

    Overview of Whatsminer M30S++

    WhatsMiner M30S++

    Price and power

    The M30S++ is priced at $3250 in MicroBT's online store, making it quite a bit cheaper than the S19 Pro.

    Bitcoins / month (profitability)

    Here we'll use the same assumptions we have with the other miners to keep things consistent.

    whatsminer m30s ++ profitability

    While you'll spend nearly $3,600 a year on electricity, the 112 TH/2 of the WhatsMiner M30S++ will bring you a profit of $3,611 a year. That means you'll have to dig for just under a year to recoup your initial investment.

    whatsminer m30s+ rentability

    Power supply and consumption

    The M30S++ requires 3472W and operates at an efficiency of 38 J/TH.

    Temperature

    The WhatsMiner M30S++ again works best between -5 and 35 degrees Celsius (23-95 Fahrenheit).

    Verdict: M30S+ and M30S++ are right for you?

    The top model M30S++ with 112 TH/s means it competes directly with the AntMiner S19 Pro.

    However, the M30S series models exhibit less hashing power than the AntMiner equivalents. They consume more power and are slightly less efficient at converting to terahash.

    However, you get more hashing power per dollar invested with MicroBT's WhatsMiner offerings. And AntMiners are highly sought after by the biggest miners in the world, making it difficult to tap into one.

    Overall, the WhatsMiner M30S series is a phenomenal bitcoin miner, with hashing power rivaling AntMiners.

    If you can get a good deal on the WhatsMiner M30S, use our calculator to see how long it will take you to make a profit on your investment.

    Another worthy contender

    Canaan AvalonMiner 1246

    Canaan AvalonMiner 1246

    Canaan is the first company to produce commercial ASIC Bitcoin miners. It is safe to say that they have some experience in this field.

    So how does their latest offering - the AvalonMiner 1246, released in January 2021 - stack up against the competition?

    Let's dive in.

    Price and power

    AvalonMiner 1246 emits 90 TH/s. This makes it comparable to AntMiner S19 and WhatsMiner M30S.

    It retails for about $5,500, making it quite a bit more expensive than Bitmain and MicroBT's offerings.

    Bitcoins / month (profitability)

    The Canaan AvalonMiner 1246 should make you a profit by giving you access to electricity at or around the U.S. average price of 0.12 $/kWh.

    avalonminer yield 1246

    It will take about two years of mining to recoup your initial investment.

    Power supply and consumption

    The AvalonMiner 1246 draws 3420W to the wall.

    Compared to the AvalonMiner 1146, the energy efficiency of the 1246 has improved by 37%: from 52 J/TH to 38 J/TH.

    It generates a maximum of 75 dB during operation, making it noticeably quieter than the WhatsMiner M30S or AntMiner S19.

    Temperature

    The AvalonMiner 1246 works best between -5 and 35 degrees Celsius (23-95 Fahrenheit). This is a wider range than the AntMiner S19 series and is equal to that of the WhatsMiner M30S.

    Verdict: How does the AvalonMiner 1246 stack up?

    With Canaan, you know you're getting a battle-tested product.

    However, the AvalonMiner 1246 does not offer the most terahashis per dollar spent. If you're looking for the most hashing power, Bitmain's S19 series and MicroBT's M30S have it beat.

    Difficulties in extraction and centralisation

    Bitcoin's difficulty has registered several strong and often consistent monthly increases since its inception. The network has seen a significant increase in hashrate since halving in July 2016.

    In the nearly five years since then, the network's total hashrate has risen more than 100-fold from ~1.5 EH/s (exhases per second) to 168 EH/s.

    The current all-time record occurred on February 8, 2020, when bitcoin miners collectively brought 175 EH/s of hashing power to the network.

    Such tremendous growth has been spurred by large investments in bitcoin mining technology and operations.

    While such growth has been impressive, making Bitcoin the world's most powerful computing network to date, one unintended consequence of such rapid growth has been increased centralisation.

    Profits have accrued where mining is most profitable (China), resulting in several competing operations (e.g. KNC ) have been pushed out of the industry.

    We have tried to estimate the amount of money that the Chinese have invested in mining, we estimate that it is in the hundreds of millions of dollars. Even with free electricity, we can't see how they will ever get that money back. Either they don't know what they're doing, but that's not very likely on this scale, or they have some secret advantage that we don't know about. Sam Cole, KNC CEO

    The same Chinese competitive advantage is doubly effective in driving the profit-dependent amateur miner out of the market.

    At this stage, most home or office miners are not in a hurry to make money, but rather to maintain the network, support decentralization, and possibly even heat the space.

    As it approaches half the block reward , the profitability of all but the most efficient operations is likely to be challenged.

    Profits derived from the current generation of mining hardware are declining and will likely reach negative returns when the next one halves.

    What is CompassMining?

    CompassMining is what is known as a "colocation mining company".

    Basically, ordinary people who can't afford to start a mining farm or get dozens of ASIC miners can partner with a company like CompassMining.

    With Compass, you simply create an account and then go through the purchase process.

    You will choose some ASICS to buy.buy asics compassmining

    You will then choose a hosting package at one of CompassMining's many state-of-the-art facilities.

    Each facility comes with its own power costs and security features. For example, the Colorado, USA location requires biometric access for all personal.buy asics compassmining

    And then you pay by card, bank transfer or (for a small discount) cryptocurrency.

    QUICK TIP

    If you want to pay by bank transfer, select "Pay by Stripe" and then select "Bank Transfer" from the pop-up window.buy asics compassmining

    Once you make your purchase, your hardware will be delivered to your designated hosting location where it will be installed and maintained by CompassMining staff.

    You'll be able to monitor and control all your mining activities from the comfort of your own home, without the headache of running a mining farm on your own.

    And best of all, you can take advantage of CompassMining's fantastic electricity rates without having to strike a deal with a major power company on your own.

    In return, Compass makes money from the hosting fees and hardware you buy through them.

    Final thoughts

    Mining bitcoins at home has almost become an impossible task these days.

    Not only are the devices expensive, but they also generate a lot of heat and noise, not to mention the amount of electricity they consume.

    This makes it inconvenient and almost impossible to make a profit!

    Unlike Antminer S9, S7 or Antminer S5, with Antminer R4, Bitmain is targeting the home market of bitcoin miners.

    This is a home-grown bitcoin miner that can actually make a profit, unlike bitcoin USB miners.

    Some of these issues mentioned above have been addressed and as a miner you can do it as a hobby while making money.

    This homemade bitcoin miner is not only suitable for hobby miners, but also helps improve the decentralization of bitcoin mining in general.

    The more distributed the hash power, the stronger the bitcoin network!
