A Bitcoin mining provider is a company that sells access to mining to private individuals, either as their own hardware for home use, as colocation in a third-party data center, or as rented computing power. These three models differ less in price than in the question of who owns the device and who owns the yield.
For private individuals in Germany, practically only the first option remains. Colocation usually requires machines from around 2,500 watts, and rented hashrate is by design a losing proposition.
The hard numbers, all verifiable: A Bitaxe Gamma 601 with 1.3 TH/s consumes around 149 kWh per year, which is 46 to 52 euros in electricity costs. The chance of finding a block is 1 in 13,224 per year, with a reward of 3.125 BTC plus transaction fees, currently around 170,900 euros. This results in a statistical annual return of 12.92 euros. This is less than the electricity costs. Solo mining is mathematically a losing business with a very asymmetrical chance, not an income model.
Compared to the May 2026 version, the following values have been brought up to date:
Electricity costs: now 46 to 52 euros per year at 31.1 to 35 cents per kWh (previously 10 euros, this value only applies to self-generated solar power).
Block value: now around 170,900 euros at 54,677.30 euros per Bitcoin, depending on the exchange rate and with a timestamp (previously a fixed figure of around 300,000 euros).
Chance of winning: now 1 in 13,224 per year, calculated from the current difficulty. The 52,560 blocks per year are still correct, but they represent the number of draws, not the probability.
Power consumption: now 15 to 19 watts as the actual range in factory operation (previously a flat 15 watts).
Anyone looking to start Bitcoin mining in Germany in 2026 faces offers that at first glance sell the same thing but differ in one crucial point: who ultimately owns the device and where the revenue goes.
Here are the four models, each with its own calculation.
What types of Bitcoin mining providers are there anyway?
The provider landscape seems confusing because everyone calls themselves something different. In reality, there are exactly four models, and the differences are fundamental.
Model one, buy hardware and operate it yourself. You buy a device, set it up at home, and pay for your electricity. In solo mining, the earnings go directly to your own Bitcoin address because your address is in the Coinbase transaction of the block. No third party involved. This is the model we operate in, and yes, that is a biased statement.
Model two, buy hardware and have it hosted. Colocation. You pay for the device, a data center provides space, electricity, and cooling. For industrial machines, this is often the only realistic operating form, because 3.5 kilowatts of continuous load do not work in an apartment. The catch for private individuals with small devices: Hosting providers typically require machines with at least 2,500 watts. No one will accept a device with 17 watts there.
Model three, rent computing power. Cloud Mining. You don't buy a device, but a contract for hashrate. More on this below, because this is where it gets unpleasant.
Model four, build it yourself. The Bitaxe project is open source, circuit diagrams and firmware are publicly available. Anyone who can solder and enjoys troubleshooting can build their own device. For everyone else, this is a hurdle, not an option. I explain what an ASIC is in the introduction to ASIC miners.
What does a Home Solo Miner really cost per year?
Here's the calculation in three steps, each verifiable.
The electricity. A Bitaxe Gamma 601 consumes 15 to 19 watts in factory operation, averaging around 17 watts. Multiplied by 8,760 hours, this results in 149 kilowatt-hours per year. At household electricity prices of 31.1 to 35 cents per kilowatt-hour, that's 46 to 52 euros, or about 4 euros per month.
The chance. The expected waiting time for a block is difficulty times 2 to the power of 32 divided by the hashrate. With a difficulty of 126,231,507,121,868 and 1.3 trillion hashes per second, that's 417,046,303,702 seconds, or 13,224 years. I queried the difficulty today via the Public Pool network interface at block height 960,520 and cross-checked it with the retarget history on mempool.space.
The expected value. A block brings 3.125 BTC plus transaction fees. At 54,677.30 euros per Bitcoin (Kraken, August 1, 2026, exchange rate dependent), that's around 170,900 euros. Divided over 13,224 years, that leaves 12.92 euros per year.
Is hosting worthwhile instead of operating it at home?
For small devices, the answer is simply no, and for a technical reason, not a moral one. Colocation centers calculate per rack space and per kilowatt. A device that draws 17 watts incurs the same administrative effort as a machine with 3,500 watts and generates one two-hundredth of the revenue. That's why the terms and conditions usually specify a minimum power of around 2,500 watts.
For industrial hardware, however, hosting is a sensible product. The German provider MILLIONMINER, for example, states its electricity price at 0.07 to 0.08 US dollars per kilowatt-hour, which is a completely different order of magnitude compared to German household prices of around 0.35 euros. That's precisely the point: industrial mining works where electricity is cheap, and it isn't in a German living room.
The question you should ask with any hosting contract, however, is not about the price. It is: What happens to my device and my assets if the operator becomes insolvent? The case of Poolin, where around 11,700 customers were left with unsecured claims totaling over 163.7 million US dollars, showed how unpleasant the answer can be. I have written about this in detail.
Why is rented hashrate almost always a losing proposition?
This calculation fits on a beer coaster, and it's why I don't argue about cloud mining.
The fair market value of 1.3 TH/s in solo mining is currently 12.92 euros per year. This is not an opinion; it is the expected value derived above. A provider who rents you the same computing power for 30 euros per year is therefore selling you something that statistically yields less than it costs. A provider who rents it to you for 8 euros would logically operate it themselves and keep the profit. The fact that they don't should make you suspicious.
In addition, there's the question of trustworthiness. The BaFin already published a consumer notice on cloud mining on February 13, 2023, explicitly advising skepticism because providers may simply keep the deposited money. I have fully calculated this topic in a separate article on cloud mining.
Our entry-level model from the Eco Line delivers approximately 1.3 TH/s at about 17 watts, is hand-assembled in Bavaria, tested under load, and delivered with a suitable power supply. It's at your place, it belongs to you, and any block found goes directly to your address. We tell you the 46 to 52 euros in electricity costs per year upfront, not afterwards.

How do you recognize a reputable Bitcoin mining provider?
Four checks, in this order. They will cost you twenty minutes and, in case of doubt, save you the effort.
First, ownership. Is the hardware at your place and do you own it? If yes, most of the following questions are settled. If no, clarify the insolvency issue first.
Second, payout method. Do the earnings go directly to your Bitcoin address or to an account with the provider? For solo mining through one of the established solo pools, it's the first option, because your address is in the Coinbase transaction. Which pools are suitable for this and why the fee question is overestimated is explained in the Solo Pool Comparison.
Third, the annual statement. Compare the acquisition costs, electricity, and fees with the statistical annual return. If an offer costs more per terahash than it statistically yields, it is mathematically a loss. This applies even if the provider works flawlessly.
Fourth, imprint and history. Serviceable address, commercial register entry, independent reviews, comprehensible company history. If any of these are missing, it is a disqualifying criterion, no matter how good the return sounds. And conversely, if these points are met, there is no reason for blanket suspicion.
How does a Home Solo Miner compare to lotteries and industrial miners?
To keep the magnitudes clear, here's a direct comparison. The Bitaxe operates at 1.3 TH/s at about 17 watts, while the industrial reference is based on 270 TH/s at 3,500 watts, both chances stemming from the same difficulty.
| Bitaxe Gamma 601 | Eurojackpot | 3,500-watt Industrial Antminer | |
|---|---|---|---|
| Chances of winning per year | 1 in 13,224 for a whole block, reward 3.125 BTC plus transaction fees, directly to your own address. The device participates in all 52,560 blocks of the year without you having to do anything. | 1 in 139,838,160 per play and draw, self-calculated using combinatorics. If you play once a week, you get 52 attempts a year. | 1 in 64, making it numerically clearly the best. Same reward, but requires an environment where 3.5 kilowatts of continuous load are affordable. In Germany, that's not a living room. |
| Running costs in home office | 149 kWh per year, so 46 to 52 euros at 31.1 to 35 cents per kWh. No hosting fee, no contract term. Runs on any normal outlet next to the router. | No power consumption, but a new stake with each draw. The played ticket is worthless after the draw and must be replaced, otherwise you are out. | 30,660 kWh per year, so 9,535 to 10,731 euros at the same electricity prices. Plus noise that is not feasible in an apartment, and waste heat that must be dissipated. |
| Drawer hazard (boredom factor) | Low. The device is visible, shows live hashrate and best share, and there's enough to adjust to keep curiosity alive for months without it becoming work. | High. Nothing happens between submission and draw, after which the ticket is just paper. There's nothing to observe and nothing to adjust. | Very high in residential areas. Such machines regularly end up in basements or resold by private individuals because noise and electricity bills outweigh curiosity. |
| Learning effect & Blockchain fascination to touch | High. Whoever sets up the device themselves will then understand Coinbase transactions, shares, difficulty, and block templates. The knowledge remains, even if a block never comes. | None. Marking five numbers and two Euro numbers does not convey anything about a system, because there is no system to understand. | Present, but not experienceable. If you put the machine in a data center, you only see a dashboard and a bill in the end. |
Which model would you recommend to someone today?
If you're interested in money: none. Mathematically, all four options are losing propositions for private individuals in Germany, and the most honest advice is to skip it and spend the 149 euros elsewhere.
If you are interested in the subject, the answer is clear. Buy a small device that belongs to you, put it in a visible place, and accept the 39 euros annual loss for what it is: the price for a lottery ticket that never expires, and for a piece of technology that truly helps you understand the Bitcoin network. Anything that sells you a contract instead takes away exactly this part.
By the way, a device as a gift is a surprisingly good idea, I've written something separately about that.

Frequently Asked Questions about Bitcoin Mining Provider Comparison
Which Bitcoin mining provider is worthwhile for private individuals in 2026?
Practically only buying your own Home Solo Miner. Colocation requires devices of about 2,500 watts or more, rented hashrate costs more than it generates by design.
What are the annual electricity costs for a Home Solo Miner?
Around 149 kWh, which is 46 to 52 Euros at 31.1 to 35 cents per kWh. About 4 Euros per month. Only those who generate their own electricity through photovoltaics will get down to about 10 Euros per year.
What is the chance of finding a block?
1 in 13,224 per year at 1.3 TH/s and current difficulty. Reward 3.125 BTC plus transaction fees, currently around 170,900 Euros, currency-dependent.
Is Cloud Mining reputable?
The BaFin has expressly advised caution since February 2023. Regardless, the model fails due to the calculation, as profitable hashrate would not be leased.
Can I make money mining at home?
On statistical average, no. The annual loss is around 39 Euros. The appeal lies in the asymmetric chance, not in an ongoing income.
Where can you verify this information yourself?
Warning on cloud mining offers: BaFin, Consumer Information dated February 13, 2023. Information on location, market affiliation, and hosting electricity prices of MILLIONMINER: BTC-ECHO, Experience and Test, as of August 2026.
