Cryptocurrency mining has become a crucial topic in today’s financial landscape. With the growing popularity of digital currencies like Bitcoin, Ethereum, or Monero, many people today are questioning the real profitability of an activity that, at first glance, may seem very lucrative. However, behind this promise of potential gains lies complex mechanisms and significant costs that directly influence the net profit of a day’s mining. So, what are the actual revenues generated by 24 hours of mining, and what does this investment really entail?
In a context where innovative machines such as Bitmain’s Antminer or NVIDIA and AMD graphic cards dominate the market, the balance between computing power, electricity consumption, and associated costs proves vital. Furthermore, the regular fluctuations in cryptocurrency prices on platforms like Coinbase, Binance, Kraken, Ledger, Bitstamp, and Gemini add an additional layer of uncertainty.
This report presents a detailed and educational analysis on how to calculate the profitability of a day of mining, the key factors affecting the results, and the various options available to optimize revenues while minimizing risks.
The Basics of Cryptocurrency Mining Profitability: Understanding the Fundamentals
The profitability of a day’s mining is often presented as the result of a simple calculation between the generated income and the incurred costs. However, behind this apparent simplicity lies a much more complex equation. Mining, in other words, validating transactions on a blockchain, requires very high computing power, achieved through specialized machines. These machines, the most famous of which are Bitmain’s Antminer, consume a significant amount of electricity. The cost of this energy, combined with the purchase price of the equipment, operational expenses, and fluctuations in cryptocurrency values, ultimately determines the real profitability.
Several elements play a key role in this calculation:
- The cost of electricity: Depending on the location, this cost can vary significantly. In France, for example, the average price is around €0.21/kWh, a factor not to be overlooked as machines like the Antminer consume on average 3150 Watts.
- Computing power: Expressed in terahash per second (TH/s), this measure indicates the speed at which your equipment solves the calculations necessary for mining. The higher it is, the greater your chances of validating a block and thus earning rewards.
- Network difficulty: This parameter, regularly adjusted, reflects the competition and the total computing power of the network. An increase in difficulty means that mining becomes more challenging.
- Crypto rewards: For each validation, a certain amount of crypto is assigned. For Bitcoin, the reward is currently several fractions of BTC per block, this amount being subject to periodic halvings that gradually reduce gains.
- Pool fees: Miners often group together in pools to increase their odds of discovery. These groups take a percentage of the participants’ earnings.
In summary, profitability is calculated using the formula:
Revenue generated – Cost of electricity – Equipment depreciation – Other expenses = Net profitability.
It is essential to specify that the crypto market is volatile, which means that the price of mined currencies can fluctuate rapidly, directly impacting the potential earnings of each day of mining.
The Economics of a Day of Mining: Decoding Costs and Profits
To evaluate how much a day of mining actually yields, it is essential to delve into the details of expenditure and income items. Imagine a miner using a Bitmain Antminer S19 Pro, which offers an average hashrate of 110 TH/s for an electricity consumption of approximately 3250 watts.
With an electricity rate set at €0.21/kWh, this machine consumes:
- 3.25 kW x 24 h = 78 kWh
- Daily electricity cost = 78 kWh x €0.21 = €16.38
Next, according to recent fluctuations in the Bitcoin network and the current mining difficulty, such a hashrate can yield between €30 and €50 per day in the form of recovered Bitcoin. However, the electricity cost must be subtracted to arrive at the net gain.
Here is an estimated summary table for a typical day of mining:
| Element | Value | Comment |
|---|---|---|
| Electric power consumed | 78 kWh | Based on 3250 watts over 24h |
| Electricity cost | €16.38 | Average rate in the euro zone |
| Gross mining income | €35 | Variable depending on Bitcoin price and difficulty |
| Pool fees | €1.75 | Generally 5% of income |
| Daily net income | €16.87 | Before equipment depreciation |
The initial cost of a new Antminer S19 Pro is around $10,000 to $12,000. The depreciation over a period of 2 to 3 years must therefore be taken into account. Over 3 years, this amounts to about €9 to €11 per day.
Taking depreciation into account, the daily net profitability becomes almost zero, or even negative in some cases.
This profitability also heavily depends on market flows on reputable platforms such as Binance or Kraken, where selling mined Bitcoins may generate more or less profit depending on market conditions.
Here is a list of variables that can positively or negatively influence this profitability:
- Evolution of Bitcoin price
- Increase or decrease in mining difficulty
- Tax opportunities or energy subsidies
- Maintenance and reliability of machines
- Type of mined crypto (Bitcoin, Ethereum PoW, Monero, etc.)
Essential Mining Equipment in 2025: Performance and Energy Consumption
The success of your mining activity relies significantly on the quality and power of your equipment. In 2025, several machines emerge as essential references in the mining market.
