What affects mining profitability?

Introduction : 

In 2025, Bitcoin mining is still a very lucrative business. It can be very profitable, but it also depends on various factors. This article follows on from our previous one, so it is necessary that you have read the latter before learning more about the profitability of this activity.

Being profitable is a delicate balance between hardware performance, electricity costs, network competition, and market volatility.

Let’s dive into these key factors. After this article, you will have a strong base to understand how profitability works when mining Bitcoin. 

1. Hardware efficiency 

Mining equipment is the foundation of profitability. Before purchasing a miner, it is crucial to compare miners, their consumption (wattage), and the hashing power they deliver (hashrate).

At the end of the day, what truly matters is the ratio of wattage to hashrate, because it’s basically the same ratio as the cost to run the ASIC/BTC produced. 

You want to go for a miner with a high hashrate relative to its consumption. Which will ultimately shorten the estimated ROI. 

2. Miner types

It is also important for you to pick an ASIC that your preferred hosting provider is able to host. 

ASICs fall into 3 main categories. 

What differentiates them is the way they are cooled down. A miner’s temperature can go very high while running. 

There are hydro-cooled miners, immersion-cooled miners, and air-cooled miners.

What we call hydro miners are simply water-cooled ASICs. 

Immersion-cooled miners are submerged in a dielectric fluid. 

Air-cooled miners are often stored in containers or bigger infrastructure with fans blowing to cool them.

Why are these characteristics so important? 

Well, because the first two categories are more efficient and the lifespan of the machine is extended, it also means the hosting provider has to have a specific infrastructure to run your miners. 

Make sure to have all the infrastructure details from your hosting provider before purchasing.

3. Electricity costs

Now that we talked about efficiency, let’s dive into the largest expense when running an ASIC : electricity. 

Access to low-cost energy is more important than ever. Electricity is way cheaper in some areas of the world. But it sometimes means less security. It can be a little more expensive to ship your ASICs to the US and host them there, but the safety of your machine and the way it is managed are either going to make or break your mining operations. 

To remain competitive, we offer rates starting as low as $0.059. 

4. Bitcoin Price

Your mining rewards are denominated in Bitcoin. However, all your expenses are in fiat currencies (dollars, euros, etc.).

Thus, your real profitability depends heavily on the Bitcoin price at the time you sell your mined coins.

You can also HODL, of course, and wait for a better price to sell. But it means you will need to cover expenses such as equipment and electricity without selling BTC.

It can be a very profitable strategy if you believe in long-term Bitcoin growth.

However, it is important to note that Bitcoin price has highs and lows, which ultimately affect the ROI.

When purchasing your miner, make sure to consider multiple price scenarios before making a final decision on which model to buy. 

5. Mining Pools

Solo mining has become impossible without massive infrastructure. Without joining a pool, you will have to let your ASIC run and cover the expenses without even knowing if you are ever going to validate a block (and get the rewards).

That being said, if you only plan to purchase and run one or dozens of miners, you will have to join a mining pool to ensure steady payouts.

Mining pools have different payout models. The most common are: 

• PPS (Pay-Per-Share): Guaranteed, steady income per share submitted

• Proportional: Income varies depending on blocks found

• FPPS/PPS+: Includes both block rewards and transaction fees in payouts

We advise you to choose a pool with low fees, a strong reputation, and a payout method that matches your financial goals.

Of course, we can help you find the one that suits you best. You can also compare pools using this real-time comparison tool here. 

To ensure steady payouts for you, mining pools usually charge between 1 and 4% of your BTC production.

6. Mining Difficulty & Halvings

These two key variables play a critical role in shaping your estimated return on investment. We will deep dive into the topic of mining difficulty in another other article but it was important enough to mention it here as well. 

Let’s keep it simple: roughly every two weeks, the Bitcoin network automatically adjusts its mining difficulty depending on how many miners are competing to validate blocks.

If it’s too easy to find blocks (blocks are validated faster than they should), then the difficulty increases to make it more competitive again, maintaining the 10-minute block time rule. 

Over time, as difficulty increases, your share of block rewards decreases. Even if your machine’s performance stays the same.

This means your ROI can decline over time, especially if your hardware becomes less competitive.

However, the most energy-efficient ASICs remain profitable longer during difficulty increases.

Every four years when the halving occurs, the number of new bitcoins created per block is cut in half.

Which ultimately means revenue per block is instantly reduced by 50%. To offset the impact of the halving, the Bitcoin price would have to double pretty much instantly. Which is usually the case on a longer term, but it will certainly have an impact on your short-term profitability, especially if you mine to sell and not hold (if you sell to cover the energy costs, for example). 

Miners who can survive immediately after a halving often benefit from long-term price appreciation, making mining a strategic long game, not just a short-term profit machine. 

7. Initial setup, maintenance costs, shipping and taxes

Beyond ASICs and electricity, don’t overlook:

• Infrastructure costs (that a portion can be passed to you)

• Spare parts and repairs

• Shipping and import taxes (for hardware purchases)

If you want to get into bitcoin mining, calculate your full cost per mined Bitcoin, not just your machine’s price.

Long story short, here’s how to maximize your profits : 

• Invest in high-efficiency ASICs (low energy consumption, stable performance)

• Choose professional hosting providers offering optimized energy and maintenance costs

• Join a reputable mining pool with transparent fees

• Stay updated on Bitcoin network changes and market trends

• Plan long-term: Bitcoin rewards decrease, but price increases can offset it
