Bitcoin Mining 2026: Is It Still Worth It in Hungary?
This is the question I get asked at least once a week: "Kálmán, is it worth mining at home?" The short answer: probably not. But the long answer is much more interesting, because there are many lessons behind the numbers. So come on, let's break it down in detail!
The Starting Point: What's the Situation in 2026?
Before we calculate anything, let's look at the environment:
- Block reward: 3.125 BTC (since the 2024 halving)
- Difficulty: near all-time high — the network hashrate is continuously growing
- BTC price: fluctuating, but for calculations we can estimate ~$85,000-95,000
- Hungarian electricity prices: well, this is where it gets interesting
Hungarian Energy Prices in 2026: The Miner's Nightmare
In Hungary, there are two electricity price categories for household consumers:
| Category | Price (HUF/kWh) | Condition |
|---|---|---|
| Subsidized | 36.9 HUF/kWh | Max. 2,523 kWh/year |
| Market price | 70.1 HUF/kWh | Above 2,523 kWh |
Pay attention to that 2,523 kWh annual limit! This is the condition for the subsidized rate, and it's the key to our calculation. For comparison: the average European mining farm operates on electricity at 4-6 cents/kWh (15-24 HUF/kWh). We're at more than three times that at market rates.
The Hardware: S21 XP vs S19 Pro
Let's compare two popular models:
| Feature | Antminer S21 XP | Antminer S19 Pro |
|---|---|---|
| Hashrate | 270 TH/s | 110 TH/s |
| Consumption | 3645 W | 3245 W |
| Efficiency | 13.5 J/TH | 29.5 J/TH |
| Daily consumption | 87.48 kWh | 77.88 kWh |
| Estimated daily BTC revenue | ~$15-20 | ~$6-8 |
| Machine price (new) | ~$5,000-8,000 | ~$1,500-2,500 (used) |
The S21 XP is decidedly a better machine — but both have brutal power consumption.
The Big Calculation: S21 XP in Hungary
Now, here comes the important part. Let's take the S21 XP and do the math:
Daily power consumption
3645W × 24 hours = 87.48 kWh/day
At subsidized rate (36.9 HUF/kWh)
Daily electricity cost: 87.48 × 36.9 = ~3,228 HUF/day
But there's a huge problem: with the annual 2523 kWh allowance, this is only enough for 28.8 days !
728×90 or responsive
2523 kWh ÷ 87.48 kWh/day ≈ 28 days
Yes, you read that right. In one month, you'd use up your entire annual subsidized allowance. And after that? It continues at market price.
At market price (70.1 HUF/kWh)
Daily electricity cost: 87.48 × 70.1 = ~6,132 HUF/day
On a monthly basis: ~183,960 HUF, which is roughly $470-500/month
Revenue vs. Cost — The Brutal Reality
With the S21 XP in 2026, you can realistically expect daily $15-20 BTC revenue (this heavily depends on difficulty and BTC price).
| Scenario | Daily revenue (HUF) | Daily electricity cost (HUF) | Daily profit/loss |
|---|---|---|---|
| Subsidized (for 28 days) | ~6,000-8,000 | 3,228 | +2,772 — +4,772 HUF |
| Market price (rest of the year) | ~6,000-8,000 | 6,132 | -132 — +1,868 HUF |
At market price, the whole thing hovers around break-even, or is outright unprofitable. And this is in the best case, when everything runs smoothly. We haven't accounted for:
- Machine depreciation (~$5,000-8,000 investment)
- Additional cooling costs (in summer you need AC in the room, otherwise the machine dies AND so do you)
- Internet, maintenance, potential repairs
- The increasing difficulty (which continuously reduces revenue)
ROI Calculation: When Does the Investment Pay Back?
Let's be optimistic and calculate with an average daily profit of ~2,000 HUF (which I think is too optimistic, but let's go with it):
Machine price: ~$6,500 ≈ 2,600,000 HUF
Daily profit: ~2,000 HUF
ROI: 2,600,000 ÷ 2,000 = 1,300 days ≈ 3.5 years
3.5 years! And this is the optimistic version. In reality, difficulty increases, machines become obsolete, and the BTC price isn't guaranteed to go up either. In my experience, the actual ROI would be more like 4-5 years — if it ever comes back at all.
Are There Alternatives?
Of course! Here are some thoughts:
- Combined with solar panels: If you have your own solar system, free electricity completely changes the equation. With a 10-15 kW system, you could mine almost for free during summer days.
- Hosting service: Send your machine to a country with cheap electricity (Kazakhstan, Paraguay, certain US states). Even with hosting fees, it can work out better.
- Only in winter, as heating: I'm serious! The S21 XP produces 3.6 kW of heat energy. During heating season, you at least save on the heating bill. Turn it off in summer.
- Cloud mining: While you need to be careful with scams, there are legitimate providers (NiceHash, Genesis Mining).
My Opinion
Honestly? In 2026 in Hungary, mining Bitcoin at market electricity rates is financially irrational. The numbers simply don't work. However, if:
- You have solar panels
- You do it as a hobby and profit isn't the main goal
- You strategically want to accumulate BTC and believe in long-term price appreciation
- You have access to discounted industrial electricity
…then it's a different situation. But if you're exclusively seeking profit, you're better off simply buying BTC on an exchange. Invest the same amount you'd spend on hardware and electricity — and you don't have to worry about difficulty, noise, heat generation, and breakdowns.
