Why ASIC Devices?

Bitcoin Mining can turn out to be a very rewarding venture for a miner.

But, getting along with solving the complex mathematical puzzle of hashing needs expensive, power-consuming hardware.

That’s not all, a keen understanding of the processes that drive blockchain technology is critical to have a complete working system.

It may look quite easy to put together some piece of equipment and just mine bitcoins, but there are some factors you should consider as price is not the most important metric for evaluating a mining hardware.

Before going into mining, you have to know your competition, understand how they operate and make a profit. Cost management is another side to it as overheads could skyrocket and dip into your profits.

You really have to know what you’re doing to succeed and it all starts with the kind of mining hardware you procure.

To harness Bitcoin, you’ll need to obtain a Technoscientific BTC Mining hardware known as ASICs (Application-Specific Integrated Circuit devices).

With several ASICs in the market today such that they have advanced through a very aggressive Bitcoin mining arms race, the blockchain network makes use of huge amounts of processing power to compute very complex mathematical equations and safeguard its network, compelling available mining hardware to continuously gain more power.

When exploring various ASIC hardware for Bitcoin mining, you have to compare the power of the hardware to the amount of energy it requires to function with maximum efficiency.

And, this translates to checking the kilowatt/hour rate of electricity consumption in your operation base or locality.

Other things to look out for in a piece of mining hardware are hash rate Mh/s, algorithm type (Ethash, SHA-256), and noise output in decibels (dB).  We will discuss this in detail much later.

What is an ASIC BTC Miner?

ASICs are specialized bitcoin mining devices, BTC producers, or bitcoin mining machines. These days, all types of bitcoin mining are done on exclusive bitcoin mining hardware, ASICs mostly in thermo-regulated data-centers that use cost-effective electricity. 

What to Consider when Choosing a Bitcoin Mining Hardware

At the inception of Bitcoin, mining could be done on a regular desktop  PC using a CPU with a comparatively high RAM.

As the blockchain ledger started expanding, so the mathematical processes needed to safeguard the network became more intricate, compelling miners to switch to more sophisticated GPUs to generate the hashing power required to mine.

Let’s look at three vital factors to look out for when choosing bitcoin mining hardware:

Efficiency ratio of the Mining Hardware

A BTC mining hardware is designed basically to transform electric power into BTC. If you’re not sure about the best bitcoin mining hardware to go for, look for one with a good energy efficiency ratio is the place to start. 

Mining efficiency translates to mining profitability. And, you can derive the efficiency of mining hardware by calculating the ratio between accepted and rejected shares.

Mining Efficiency Ratio: Accepted Shares /(Accepted Shares + Rejected Shares)

Efficient mining hardware should give a mining output of almost 100% per Kilowatt/hour of electricity it consumes as anything lower means low profitability.

Best Bitcoin Mining Hardware

The graph above shows the return on investment on 5 different hardware between 8-12 months of mining operations.

Usually, mining hardware goes through a depreciating lifecycle of 2-3 years after which it starts losing steam and starts becoming less profitable. Certainly, newer versions of mining hardware would have entered the market to relieve the outdated ones.

Mining Hardware Price

Pricing for mining hardware differ, factors such as longevity, computing strength, working efficiency, and brand stack up to determine its price.

Sometimes, cheap hardware does not necessarily mean that it will underperform, it is just that, it may be deficient in some other areas that may not be a priority to you.

However, electricity consumption should be a major consideration because this alone can raise your overall running cost of the equipment thereby reducing your mining net profit.

When performing a commercial analysis on mining hardware, pricing may be tricky as a very expensive one may not necessarily mean that it would serve all your needs.

A cheap one may also be mining profitably but may have a large appetite for power. Bottom-line is that you should examine hardware features while considering your budget as well.

For profitability which certainly is why you are researching on which hardware to buy, see what we found as profitable mining hardware.  

Hash Rate

Hashing power is the system’s ability to solve a complex mathematical puzzle in less time, and this is measured in hash/Sec (H/s).

1 GH/s is 1,000,000,000 (one billion) hashes per second.

1 TH/s is 1,000,000,000,000 (one trillion) hashes per second.

1 PH/s is 1,000,000,000,000,000 (one quadrillion) hashes per second.

To explain it simply, the greater the hash rate of the hardware, the faster the mining pool/miner will compute the next block in the bitcoin blockchain.

By rule of thumb, mining hardware with a faster hash rate is better and profitable. However, you will have to spend some extra dollars to acquire one.

Other Considerations

Picking a durable BTC miner for your operations requires that you assess carefully the hash rate of each of them, power usage & temperature control regulatory requirements.

Most importantly, consider the cost of electricity in the area you plan to use your mining equipment as this will greatly help affect your profits.

In all, the best bitcoin BTC mining hardware is the most rewarding.

The technology behind the ASIC devices has progressed quickly in the last 10 years, with innovative hardware released each year to render the old hardware obsolete.

Mining Hardware Profitability

It’s possible to determine upfront the expected profitability per day of a mining hardware before you purchase. There are just a few more things to lookout for asides the cost of the hardware.

So, in addition to how profitable a mining hardware can be, you can also ascertain the hardware’s mining algorithm, noise output, hash rate, and release date. Usually, they are spelt out on the manufacturer’s site.

But, ASIC Miner Value simplifies these data in a table format where you can view features of a mining hardware at a glance.

The table above shows the mining hardware that are already in stores/market and the ones that are still in development with a scheduled release date.

Beyond the data that ASIC have provided, you can also determine the profitability of your mining hardware independently, make use of a BTC mining profitability calculator.

When calculating, ensure to factor cost of electricity as your mining project may seem rewarding until you calculate your expenses on electricity.

To determine electricity costs, research the price of electricity consumed per hash on the mining hardware label. This factor is vital and must be ascertained before you purchase a piece of mining equipment. Else, you could be chasing the wind.

Let’s narrow this down and consider a few mining hardware that are profitable in terms of daily profitability, hashing power and low electricity costs.

Taxes on Cryptocurrency Mining

Taxes on mining are usually overlooked. All mining activites are taxable, so, it is crucial you oversee your tax mining liabilities.  When you consider your mining operations and region, taxes may apply. So, check this upfront before arriving at your profits.

Bitcoin Mining Hardware Companies

There are several mining hardware manufacturing companies but we will examine three:


Bitmain is the leader of AntMiner’s line of BTC miners. It has headquarters in China and also runs a mining pool.


BitFury is among the biggest manufacturers of Bitcoin mining hardware & chips. Its hardware is not sold in the market.

Halong Mining

Halong Mining is the latest mining hardware setup with an array of top-performing mining hardware in the market. .

BTC Mining Equipment

Apart from a Bitcoin mining ASIC, there are some other piece of equipment required for Bitcoin mining.

Backup Generators

A generator will be needed as backup in the instance your only source of electricity is down or runs low.

Power Supply

BTC rigs require enormous power supply to channel and use electricity effectively.

Cooling Fans

Bitcoin mining hardware easily overheats due to the enormous power it consumes. A poorly regulated system can cause a breakdown.

But a cooling fan keeps the temperature at required levels, your hardware will also receive adequate air-flow.

Bitcoin Mining Without Hardware

You can mine Bitcoins without bothering about exclusive mining hardwares.

Though, you receive less than a penny each month. Mining Bitcoin on your computer device will damage it and won’t earn you anything.

So, you can make use of your computer only when  you just want to get a hang of the mining process.

The best option is to purchase an exclusive hardware like the AntMiner S9.

Other alternatives are to buy a buy a mining plan where the mining enterprise rents out mining quotas for a period. With this option, you focus on the mining business and forget about purchasing a hardware, electricity cost, fire or burglary.
