Let's take an objective look at the clash between two investment worlds: purchasing an apartment in a highly desirable location versus acquiring a single Antminer Z15 Pro mining rig (ASIC) with professional management from 2Bminer. The results might just surprise you.
Model Example: How to Achieve a Net Return of CZK 21,500 per Month?
To compare apples to apples, we look at real data from the recent one-month period from April 25 to May 25, 2026. Our goal is straightforward: to end the month with a clean CZK 21,500 in hand.
Path A: Operating 1 Antminer Z15 Pro with 2Bminer
An ASIC miner is a specialized computer designed exclusively for cryptocurrency mining. The Z15 Pro model operates on the Equihash algorithm and, thanks to an efficient connection to the NiceHash system, generates Bitcoin (BTC) directly.
Based on real market data, the average net monthly return for a single machine during the period from April 25 to May 25, 2026, is exactly CZK 21,500. This amount is already fully cleared of management fees and electricity costs.
A note on power consumption: Although the annual electricity cost for one machine is roughly CZK 37,000 (given our exclusive rate of USD 0.07/kWh), this cost is continuously deducted from the mining revenue. The stated CZK 21,500 per month is therefore a completely net result for you.
Path B: Renting Out an Apartment in a Regional or Capital City
To secure the same net amount from rent, you need a property that commands a premium market price. An ideal example would be a modern 2+kk (one-bedroom) apartment in the wider center of Prague (e.g., Vysočany, Holešovice) or a newer 3+kk (two-bedroom) apartment in Brno. Such an apartment can currently be rented out for approximately CZK 24,500 per month (with the tenant paying for utilities on top of this amount).
Why does the gross rent have to be higher than the net profit from the machine? The answer is taxes. After accounting for the mandatory income tax on rental income, your original CZK 24,500 shrinks to exactly that net CZK 21,500 in your pocket.
Upfront Investment: Millions vs. Hundreds of Thousands
This is where we see a fundamental difference in the amount of capital required to get started.
- For an investment apartment: To purchase a property in Prague or Brno today, you need a sum ranging from CZK 6 to 8 million. Few people have that kind of cash readily available, which means going through the process of getting a mortgage, securing your own down payment equity (LTV), and committing to years of bank repayments.
- For the Z15 Pro machine: The upfront investment ranges between CZK 200,000 and 300,000 per machine. The final price depends heavily on how long you wait to make the purchase. As the price of Bitcoin goes up in the markets, the global price of mining hardware increases proportionally. Those who buy early start with significantly lower upfront costs.
Immediate Exchange vs. the Power of "HODL"
The return of CZK 21,500 from the Z15 Pro machine mentioned above is calculated based on the assumption that you immediately convert your mined Bitcoin into Czech korunas every month.
However, if you plan your strategy ahead and decide to hold your Bitcoin (referred to as HODLing in crypto slang) until the market moves into a growth phase and Bitcoin surpasses, for example, the USD 120,000 mark, you are suddenly looking at completely different numbers. The value of the coins you mined during the past month could easily double in the future. With traditional rental income paid in fiat currency (CZK), such a massive leap in the value of already-earned income is simply impossible.
1. How Difficult Is It to Set Up? (Administration)
- For an investment apartment: You face an approval marathon to secure a mortgage – proving income, property appraisals, insurance. This is followed by searching for a reliable tenant, checking their debt/credit registries, drafting rental agreements, and transferring utility bills.
- For the Z15 Pro machine: You can handle the entire process from the comfort of your couch. You sign the contract online, and 2Bminer takes complete care of the purchase, international shipping, installation in a professional data center, and launch. Once connected, your first results begin rolling in right inside your client dashboard.
2. Ongoing Worries, Repairs, and the Dreaded Vacancy Periods
- Apartments and daily reality: As the owner, you must deal with emergencies, broken boilers, or interior wear and tear. Major inspections and modernizations are always your responsibility. You also have to factor in vacancy periods. When a tenant leaves after a year, it can take around 2 months to find a new one. During this vacancy window, you cover the building fees and any mortgage out of your own pocket, which drastically drags down your annual yield.
- ASIC with service included: With 2Bminer, you don't pay a single extra koruna for repairs. All servicing, deep cleaning, and part replacements are already included in the 20% management fee. When it comes to downtime, it only occurs for necessary maintenance. 2Bminer guarantees a 95% uptime (machine runtime). The machine works continuously, requires no vacation, and there's no risk of a tenant giving you their notice.
3. Taxes and Asset Lifespan
- Taxation: Rental income from an apartment must be reported annually on your tax return, and you have to pay income tax on it. For cryptocurrency mining by individuals, a 3-year time test applies in the Czech Republic. If you hold your mined Bitcoin for 3 years, its subsequent sale back into fiat currency is completely exempt from income tax.
- Lifespan and residual value: An apartment's lifespan spans decades, and its value increases over the long term. The lifespan of an ASIC miner under top-tier maintenance is approximately 7 years. While its value declines over time, if you buy at the right time and decide to sell the machine after 3 years of operation during a full-blown bull market, you can easily offload it on the secondary market for up to 50% of its original purchase price.
The Big Comparison: Apartment vs. Antminer Z15 Pro
| Parameter | Investment Apartment (Prague 2+kk / Brno 3+kk) | 1x Antminer Z15 Pro (2Bminer) |
| Upfront Investment | CZK 6,000,000 – 8,000,000 (or mortgage) | CZK 200,000 – 300,000 (depending on current BTC price) |
| Net Monthly Return | CZK 21,500 (from CZK 24,500 rent after tax) | CZK 21,500 (average Apr 25 – May 25, 2026, energy already deducted) |
| Upfront Administration | High (Bank, appraisals, land registry, contracts) | Minimal (Online contract in 10 minutes) |
| Physical Hassle | Finding tenants, repairs, HOA meetings | Zero (Everything handled by 2Bminer within the fee) |
| Risk of Income Interruption | Yes (Average 2-month vacancy between tenants) | Minimal (Guaranteed 95% machine uptime) |
| Profit Taxation | Standard rental income tax | 0% (when meeting the 3-year time test) |
| Asset Lifespan | Decades | Approx. 7 years |
| Return Growth Potential | Limited (inflation clauses in the lease) | High (with strategic HODLing of BTC into the bull market) |
| Residual Value | Long-term growth | Declining (option to sell at ~50% in a bull market) |
Verdict: Two Paths to a Regular Yield
The goal of this comparison isn't to claim that real estate is a bad choice. Properties are well-suited for investors who command large capital, want to store wealth for decades, and don't mind handling administration and the human element.
However, if you are looking for a regular monthly return with an incomparably lower initial capital outlay—where you invest an amount in the hundreds of thousands, sign a contract online, and focus solely on your returns—modern Bitcoin mining infrastructure makes immense sense. The yield from a single mining machine is fully comparable to renting out a prime Prague apartment, but with the distinct advantage that your final payouts aren't eaten up by unplanned vacancies, expensive repairs, or taxes.
