That is why most miners use mining pools. By combining hashrate with other participants, miners receive smaller but much more predictable payouts based on their contribution to the pool.

For anyone treating Bitcoin mining as a business, predictable cash flow can be more valuable than the small chance of receiving a full block reward. Electricity bills, hardware financing and operating costs continue regardless of whether a solo miner finds a block.

Pool fees reduce revenue slightly, but they also reduce variance dramatically. A miner contributing a relatively small amount of hashrate can receive regular payouts instead of potentially waiting months or years for a successful solo block.

Solo mining therefore becomes more of a probability decision than a simple profitability calculation.

There are still situations where it can make sense. A miner with substantial hashrate, extremely cheap electricity or hardware that would otherwise be idle may be willing to accept the variance. Some smaller miners also treat solo mining almost like a lottery while contributing to Bitcoin decentralization.

I think the important distinction is between expected value and cash-flow stability. The expected mining reward may theoretically be comparable before pool fees, but the distribution of that reward is completely different.

Pool structure also matters. Different pools use payout methods such as PPS, FPPS or PPLNS, which can change how predictable earnings are and how transaction fees are distributed.

There is also a decentralization argument. If too much Bitcoin hashrate becomes concentrated in a small number of major mining pools, that can create concerns about coordination and network influence. Smaller pools and independent mining can help distribute mining activity more broadly.

So is solo Bitcoin mining ever rational today?

Would you choose predictable pool payouts or accept much higher variance for the possibility of receiving an entire block reward?

And for miners using pools, what matters most when choosing one — fees, payout method, reliability, pool hashrate, transparency or geographic distribution?

For the Bitcoin network, higher hashrate is generally positive because it increases the amount of computational work protecting the blockchain. For individual miners, however, the picture is more complicated.

As more mining power joins the network, competition for the same block rewards increases. Bitcoin’s difficulty adjustment is designed to keep block production relatively stable, so sustained hashrate growth usually leads to higher mining difficulty over time.

That means an ASIC producing the same hashrate can gradually earn less BTC if total network competition keeps increasing.

For large operators, this creates constant pressure to improve efficiency. Newer hardware, cheaper electricity, better cooling and optimized uptime can help maintain margins even as difficulty rises. Smaller miners with older ASICs or higher power costs may have a much harder time staying competitive.

I also think rising hashrate changes how miners should think about hardware purchases. Buying a machine based only on today’s profitability can be risky if network difficulty continues increasing. The more useful question is how efficient that ASIC is likely to remain over the next few difficulty adjustments.

Another factor is miner capitulation. When profitability becomes too weak, less efficient operators may shut down machines. That can temporarily slow hashrate growth or even reduce network hashrate until economics improve again.

From an investor perspective, consistently rising hashrate can also be interpreted as confidence in Bitcoin mining infrastructure. Miners are willing to deploy capital into hardware and energy because they expect the network to remain economically relevant.

But for miners themselves, stronger network security does not automatically mean stronger profitability.

How are you adjusting your mining strategy as Bitcoin hashrate continues to rise?

Do you focus more on ASIC efficiency, electricity costs, difficulty projections, pool performance or hardware upgrade timing?

And do you think continued hashrate growth will force smaller miners out, or will cheaper energy and more efficient hardware keep small-scale mining viable?

A miner paying a very low industrial electricity rate can keep operating through difficult market conditions that would force a higher-cost operator to shut down. That is why comparing mining profitability without knowing the power price can be misleading.

The basic economics are straightforward. Mining hardware consumes electricity continuously, while BTC revenue changes with Bitcoin price, network difficulty, transaction fees and the miner’s share of total hash rate. If power costs rise while mining revenue stays flat, margins can disappear very quickly.

Efficiency matters just as much as electricity price. Two ASIC miners can produce similar hash rates while consuming very different amounts of power. Newer machines with better joules-per-terahash efficiency usually have a much stronger chance of remaining profitable as network difficulty increases.

I also think smaller miners sometimes underestimate secondary energy costs. Cooling systems, fans, ventilation and other infrastructure consume additional power beyond the ASIC itself. In warmer climates, cooling expenses can materially change the final cost per mined Bitcoin.

Location therefore becomes a major competitive advantage. Mining operations built near hydroelectric power, stranded energy, renewable generation or other low-cost electricity sources can operate at economics that are impossible for miners paying normal residential rates.

Another interesting factor is flexible mining. Some operators reduce or pause mining when electricity prices spike and increase activity when power becomes cheaper. In markets with variable electricity pricing, that kind of load management can significantly improve margins.

For home miners, the calculation is even more complicated. Electricity may be expensive, but waste heat from an ASIC can sometimes be useful for heating a building during colder months. That does not automatically make the operation profitable, but it changes how the energy cost is evaluated.

At what electricity price do you think Bitcoin mining stops making sense?

Do you calculate profitability primarily through cost per kWh, ASIC efficiency, BTC price, network difficulty or total operating cost?

And for smaller miners, do you think access to cheap electricity matters more than buying the newest mining hardware?

For large industrial miners, scale creates obvious advantages. They can negotiate lower electricity rates, operate in regions with cheaper energy and deploy newer ASIC hardware more efficiently. Smaller miners usually do not have the same cost structure, which makes margins much tighter.

Electricity is probably the biggest variable. Two miners using the same hardware can have completely different results depending on power costs. A machine that looks profitable at one electricity rate can become unprofitable very quickly if energy prices increase.

Hardware efficiency also matters more than raw hash rate. Newer ASIC miners can generate more computing power while using less electricity per terahash, which gives them a significant advantage when network difficulty rises.

Difficulty is another factor smaller miners cannot control. As more hash rate joins the Bitcoin network, the same mining hardware earns a smaller share of the block rewards. That means profitability can decline even if the BTC price remains stable.

Mining pools help reduce revenue volatility, but they also introduce fees and dependence on pool infrastructure. Solo mining may offer the chance of a full block reward, but for smaller operators the probability of finding a block independently can be extremely low.

I also think smaller miners need to consider costs that are easy to ignore: cooling, ventilation, maintenance, downtime, noise control and eventually replacing aging hardware.

The biggest question is whether small-scale Bitcoin mining should still be viewed purely as a profit business. Some operators may value direct participation in the network, access to unusually cheap electricity or the ability to monetize otherwise wasted energy even when margins are relatively modest.

Is Bitcoin mining still profitable for smaller operators in 2026?

What matters most in your setup — electricity cost, ASIC efficiency, Bitcoin price, mining difficulty or pool fees?

And at what electricity price would you personally decide that running a Bitcoin miner no longer makes economic sense?
