Bitcoin mining has been around for more than a decade. It has gone from a hobby for early adopters to a capital-intensive infrastructure business. The natural question in 2025 is no longer “What is mining?” but:

Does Bitcoin mining still make sense today – and if, then under which conditions?

With the 2024 halving behind us, a block reward of 3.125 BTC, a global hashrate of around 1,000 exahash per second, and Bitcoin trading near all-time highs, the mining landscape is more competitive than ever.

Mining is no longer “plug in a machine and get rich”. It is an infrastructure decision: buying hardware, securing energy, and operating it professionally over several years.

At Kryptoberg, we see mining as structured, asset-backed exposure to Bitcoin and other leading assets – not as a speculative side project. In this article, we look at the key factors that drive profitability in 2025 and how to approach them in a rational way.

The Four Drivers of Mining Economics in 2025

Whether Bitcoin mining is profitable in 2025 depends mainly on four variables:

1. Electricity price – the single largest cost driver

2. Hardware efficiency and price – how many joules per terahash you burn

3. Network difficulty and block reward – how crowded the game is, and what you’re competing for

4. Bitcoin price and demand – the value of what you produce

Let’s walk through each of them – and then look at what this means for a real machine in a real hosting setup.

Factor 1: Electricity is still the King

Electricity remains the most important variable in the mining equation.

In 2025, analyses of industrial-scale operations show typical power costs in the $0.05–0.07 per kWh range for competitive sites, with cheaper energy available only in specific regions or via special power agreements.

Profitability scales almost linearly with power price. One recent model suggests that with efficient modern hardware and $0.05/kWh, the cost to mine 1 BTC is roughly $35,000–$45,000. If your electricity price doubles, your cost per BTC roughly does too. For European and DACH-focused miners, access to truly cheap energy is rare. That’s why Kryptoberg focuses on:

• Energy-optimised sites with all-in power (including cooling and basic operations) from around €0.09/kWh

• Locations selected for stability, contract security and uptime, not just headline price

• Using modern ASICs to squeeze as much hashpower as possible out of every kWh

  
  

The goal is simple: keep the cost per mined BTC below the market price – with a margin that can survive volatility.

Factor 2: Hardware efficiency Is Non-Negotiable

The days of running old S9s in a basement are over. With the network hashrate hovering around 1,000 EH/s and difficulty near record highs, only efficient ASICs make sense. A current example on the market is the Bitmain Antminer S21 Pro, which offers:

• Hashrate: up to 234 TH/s

• Energy efficiency: around 15 J/TH under optimal conditions

• 
  

At 234 TH/s and 15 J/TH, this translates to roughly 3.5 kW of power draw.

At €0.09/kWh, that’s about:

• ~€0.32 per hour

• ~€7.60 per day

• ~€227 per month purely in electricity

  
  

On the Scrypt side (Litecoin/Dogecoin), modern miners like the Bitmain Antminer L9 push similar efficiency boundaries for their algorithm class. Efficient hardware doesn’t just improve margin – it also extends the useful life of the machine, keeping you above break-even even if difficulty rises or prices pull back.

Kryptoberg’s stance is simple:

We only work with modern, high-quality miners compatible with leading assets such as Bitcoin, Litecoin and Dogecoin.

Old, inefficient hardware doesn’t belong in a 2025 and definitely not 2026 business case.

Factor 3: Mining Difficulty and the 2024 Halving

Every four years, the Bitcoin network cuts its block reward in half. The latest halving took place in April 2024, reducing the reward from 6.25 BTC to 3.125 BTC per block. At the same time:

• The total network hashrate has climbed to around 1,000+ EH/s in late 2025

• Difficulty adjusts regularly to this hashrate, keeping block production at ~10 minutes on average

• 
  

The result:

• Rewards per block are lower.

• Competition per block is higher.

• Inefficient or poorly located miners are simply pushed out.

• 
  

From the outside, this might sound like a reason to abandon the space. In reality, it’s the opposite: the system is designed to squeeze out weak setups and reward those with efficient hardware, good energy and professional operations.

The question in 2025 is no longer “Can everyone mine?” but “Can you mine with the right setup?”

Factor 4: Bitcoin Price and Demand

Mining economics ultimately depend on what your output is worth. As of December 2025, Bitcoin trades around $90,000–93,000 per BTC, with a significantly higher floor than in previous cycles. Institutional adoption, ETF flows and broader macro narratives have changed the profile of who holds BTC and why.

The important point for miners:

• If your all-in cost per BTC (hardware amortisation + power + hosting) is well below the market price, you are in a good position.

• If your cost per BTC is near or above the market price, you are essentially speculating on higher prices later – which can be valid, but must be acknowledged.

External analyses suggest that efficient miners on $0.05/kWh power can still produce BTC at $35,000–45,000 per coin. At higher power rates such as €0.09/kWh, this cost moves closer to the $60,000–70,000 range, but still below current prices, leaving room for margin.

This is why at Kryptoberg we always frame mining as:

A long-term exposure to the asset, backed by infrastructure, not a short-term trading strategy.

A Simple Example: One Modern Miner in 2025

Let’s bring this together using a single S21-class miner in a hosting setup similar to what Kryptoberg offers.

Assumptions (illustrative, not a guarantee):

• Miner: Bitmain Antminer S21 Pro (approx. 234 TH/s, 15 J/TH)

• Power draw: ~3.5 kW

• Electricity + hosting: €0.09/kWh

• BTC price: $90,000+ (~€82,000–85,000 equivalent)

• Network hashrate & difficulty: in line with current levels

Under these conditions, public mining calculators and third-party analyses show that:

• A modern S21-class miner remains profitable at $90k BTC on power prices up to the high-single-cent range (around $0.08–0.09/kWh).

• There is downside buffer: profitability often persists even if BTC drops significantly from current levels, thanks to the efficiency of new-generation ASICs.

The exact numbers change with price and difficulty. What matters more is the structure:

• Your fixed cost per month is clear (power + hosting).

• Your output in BTC is probabilistic but estimable given network conditions.

• Your break-even per BTC can be calculated and tracked over time.

That’s why Kryptoberg always shares example tables and projections before a client commits – and emphasizes that they are scenarios, not promises.

Why Home Mining Is Mostly Over – and Professional Hosting Isn’t

For most people in DACH, home mining is no longer attractive:

• Residential electricity prices are far above industrial rates.

• Noise and heat from modern ASICs are not home-friendly.

• Regulatory and metering questions become messy.

Industrial mining, however, is very alive – but it has moved into:

• Dedicated datacenters

• Cheap-energy geographies

• Professional hosting structures

This is exactly where Kryptoberg fits in:

• We sell only high-quality miners compatible with the market’s most valuable cryptocurrencies, including Bitcoin and Dogecoin.

• We host them in carefully selected locations with energy from around €0.09/kWh.

• We take care of deployment, monitoring and maintenance.

• We typically bring devices online in days, not weeks, once contract and payment are settled.

• Investors receive quarterly Bitcoin payouts directly to their wallets, based on the performance of their miners or fractional shares.

For clients, the experience is simple:

Choose what you want to mine and how much to commit – we handle the infrastructure.

Kryptoberg’s Approach: Mining as Structured Exposure

Mining in 2025 is not about “hitting the jackpot” or guessing day-to-day price moves. It’s about:

• Converting capex into long-term hashpower,

• Securing reliable energy and infrastructure,

• And treating mining output as a stream of BTC-denominated cashflow.

Kryptoberg structures this into clear, accessible models:

• Full ownership: buy an S21-class or L9-class miner, hosted and operated on your behalf.

• Fractional ownership: start from around €350 by co-owning a share of a miner, with proportional payouts.

• Quarterly BTC payouts: direct to your wallet; you hold the coins, not us.

• DACH-friendly communication: clear contracts, realistic assumptions, and support in plain language.

So – Is Bitcoin Mining Still Worth It in 2025?

The honest answer:

• No, if you want a quick win, home mining, or “easy passive income” without understanding the mechanics.

• Yes, if you treat it as a multi-year infrastructure allocation with clear costs, serious hardware and a professional hosting partner.

With the 2024 halving behind us, an all-time-high hashrate, and rising institutional demand, mining is increasingly a game for those who:

• Secure competitive energy,

• Use efficient, modern ASICs,

• And structure their operations professionally.

That is the space Kryptoberg is built for.

If you want to:

• Own or co-own real mining hardware,

• Get structured exposure to BTC, LTC or DOGE,

• And avoid the operational headache of running it yourself,

then mining in 2025 can still be a rational, attractive part of your portfolio – provided you do it with the right setup.

Kryptoberg’s role is to make that setup accessible, understandable and executable.
