Bitaxe Electricity Costs 2026: What a Home Solo Miner Really Pays Per Month

By Dominik Lederer · Founder, Hardware Engineer & Solo-Mining Expert · Polarblocks · July 3, 2026

There's a number that keeps circulating in solo-mining marketing, and it's misleading: "Only costs 10 euros in electricity per year." Sounds magical. But it's a lie – at least for most people. If you don't have a solar system on your roof, but rather get electricity from a regular utility provider, you'll pay more. We'll calculate exactly how much, down to the cent, honestly, without sugarcoating, and still arrive at a surprisingly small result.

What does a Bitaxe really cost in electricity per month?

Let's start with the hardware, because only real values produce a real calculation. The Bitaxe Gamma 601 operates with the BM1370 ASIC and a power consumption of 15 to 19 watts. For practical purposes, we'll assume a typical average of 17 watts in continuous operation.

The formula is elementary school, not rocket science: 17 watts × 24 hours × 365 days results in 148.92 kilowatt-hours per year. We multiply these almost 149 kWh by the electricity price. And here lies the whole trick that unscrupulous providers conceal: The electricity price decides everything.

At €0.35 per kilowatt-hour – a fair, conservative average for German households in 2026 – we arrive at around 52 euros per year. Divided by twelve, that's about 4.30 euros per month. Less than one coffee per week. And yes, significantly more than the famous 10 euros, but still an amount that hardly anyone notices in their household budget.

Why is the figure “10 Euros per year” circulating – and why is it usually not true?

The 10-euro claim is not a scam, but a missing context. It is true if you generate the electricity yourself. With a photovoltaic system, your own kilowatt-hour costs only a few cents, depending on the system. If you calculate 149 kWh at €0.07, you actually end up with around 10 euros. Without solar on the roof, this figure simply does not apply.

So that you can gauge your own situation, here are the real electricity prices in Germany in summer 2026, depending on the type of contract:

New customer tariffs start at around 24.3 ct/kWh, existing customers pay on average 31.2 ct/kWh, and in the basic supply, it's around 42.83 ct/kWh.

In concrete terms, this means that with a favorable new customer tariff, the Bitaxe only incurs about 36 euros in electricity costs per year. In the expensive basic supply, it's around 64 euros. Our 52-euro calculation with €0.35/kWh is deliberately in the middle – honest rather than embellished.

Is it even worth it? Chances versus costs, soberly considered

Now for the part you want to hear. For these approximately 4.30 euros in electricity per month, you are not buying a guarantee of return. You are buying lottery tickets. And incredibly many of them. The Bitcoin network finds a block every ten minutes on average, so six per hour. Over a year: 6 × 24 × 365 = 52,560 draws, in which your little miner participates day and night.

Let's be as honest about the probability as we are about the electricity costs. A single Bitaxe with 1.3 TH/s has a hit chance of roughly 1 in 13,000 per year against a global network hashrate of around 900 EH/s (assumption; network performance fluctuates daily). This is a lottery, not a savings plan. But compare it to what millions of Germans voluntarily do every week: A single Eurojackpot line wins the main prize with a chance of 1 in 139,838,160. In contrast, the main prize in solo mining is an entire block: currently 3.125 BTC plus transaction fees – a six or seven-figure euro amount depending on the exchange rate.

The difference is fundamental: a lottery ticket is worthless after the drawing. Your Bitaxe Home Solo Miner simply keeps drawing the next morning. And the next. A ticket that never expires.

How does the Bitaxe perform in an honest lifestyle comparison?

Forget terahash tables and data sheets for a moment. Most people don't buy a miner for its voltage converters, but for the feeling of being part of it. So let's compare exactly that: What do you get for your money – emotionally and in everyday life – compared to a traditional lottery ticket and industrial-scale mining?

What matters in the living room	Bitaxe Gamma (Home Solo Miner)	Traditional Lottery	3500W Industrial Antminer
Chances of winning per year	52,560 chances per year – every single block, around the clock, for the full reward (currently 3.125 BTC + fees)	Only as many draws as tickets you buy – each expired as soon as the balls drop	Statistically higher hit rate, but practically unaffordable for private individuals in solo operation
Running costs in the home office	~€4.30/month (17 W, €0.35/kWh) – inconspicuous on the electricity bill	Each ticket costs extra, money constantly goes out, nothing remains	Hundreds of euros in electricity per month plus noise – a separate room is a must
Drawer-danger (Boredom factor)	Live OLED display and WLAN dashboard – you look at it every day instead of putting it away	Ticket disappears in wallet, often forgotten	Not a device for the desk – stands in the basement or data center
Learning effect & blockchain fascination at your fingertips	You really understand Bitcoin: wallet, pool, hashing – with a Noctua cooling upgrade, it's also virtually silent and suitable for the living room	Zero learning effect – pure checkbox-ticking without understanding	High learning effect, but entry barrier and volume deter beginners

In sober industrial metrics, the large Antminer wins. In everything that actually makes a miner in the living room worth living for – costs, everyday usability, fascination – the small Bitaxe wins. That's exactly what it was built for.

How can I further reduce my Bitaxe's electricity costs?

If you want to push the 52 euros even lower, you have a few real levers – no magic tricks:

1. Change electricity tariff. Switching from the basic provider (42.83 ct) to a good new customer tariff (24.3 ct) almost halves the miner's electricity costs. This is the biggest lever of all.
2. Undervolt instead of overclock. If you slightly reduce the clock rate in the AxeOS dashboard, consumption drops towards 15 watts – and thus annual costs to around 46 euros.
3. Use your own solar power. Only here does the famous 10-euro calculation become real. If the miner runs on surplus PV power during the day, the effective kWh drops to just a few cents.

“An honest 52 euros a year beats any invented 10-euro figure. Because trust is the only return guaranteed in solo mining.”

Frequently Asked Questions about the Bitaxe's Electricity Costs

How much electricity does a Bitaxe Gamma 601 consume per year?
At a typical 17 watts of continuous operation, about 149 kWh per year. At €0.35/kWh, this corresponds to approximately 52 euros annually or 4.30 euros monthly.

Is it true that a solo miner only costs 10 euros in electricity per year?
Only with your own photovoltaic system. If you use regular grid electricity, you'll pay between roughly 36 and 64 euros per year, depending on the tariff.

What is the chance of finding a block with a Bitaxe?
Roughly 1 in 13,000 per year at 1.3 TH/s and approximately 900 EH/s network hashrate. A real lottery – but with 52,560 draws annually and a ticket that never expires.
