#### **4. Estimated Daily Earnings**
Estimated daily earnings are a key consideration for any mining operation, as they determine the potential return on investment (ROI). The daily earnings from a mining device like the Antminer S21 depend on several factors, including the Bitcoin price, network difficulty, and the cost of electricity.
##### **4.1 Factors Influencing Earnings**
**Bitcoin Price**: The market price of Bitcoin is the most significant factor influencing mining profitability. As Bitcoin's price fluctuates, so too does the value of the rewards earned by miners. A higher Bitcoin price generally translates to higher earnings, while a lower price can reduce profitability.
**Network Difficulty**: Bitcoin's network difficulty adjusts approximately every two weeks to ensure that new blocks are mined at a consistent rate. As more miners join the network, the difficulty increases, making it harder to mine new blocks. Higher difficulty reduces the likelihood of solving the cryptographic puzzle, thereby lowering potential earnings.
**Electricity Costs**: The cost of electricity is a direct expense that impacts net earnings. Miners in regions with low electricity rates will have a higher profit margin compared to those in areas with higher electricity costs.
**Example Calculation of Estimated Daily Earnings**:
- **Bitcoin Price**: $30,000
- **Network Difficulty**: Variable (assume current difficulty for this example)
- **Electricity Cost**: $0.05 per kWh
- **Hash Rate**: 200 TH/s
The formula to estimate daily earnings can be simplified as follows:
\[ \text{Daily Earnings} = \frac{\text{Hash Rate} \times \text{Block Reward} \times \text{Bitcoin Price}}{\text{Network Difficulty}} \]
Assuming a block reward of 6.25 BTC and current network conditions, the estimated daily earnings for the Antminer S21 would be approximately $18 to $24, depending on the exact difficulty and Bitcoin price at any given time.
##### **4.2 Profitability After Electricity Costs**
To calculate the profitability after accounting for electricity costs, we subtract the daily electricity expenses from the estimated daily earnings.
**Electricity Cost Calculation**:
- **Power Consumption**: 4000W
- **Electricity Rate**: $0.05 per kWh
- **Daily Electricity Cost**: \( 4000W \times 24 \text{ hours} = 96,000 \text{ Wh} = 96 \text{ kWh} \times 0.05 \text{ USD/kWh} = 4.8 \text{ USD/day} \)
Thus, the net daily profit would be:
\[ \text{Net Profit} = \text{Estimated Daily Earnings} - \text{Daily Electricity Cost} \]
\[ \text{Net Profit} \approx 18 \text{ USD} - 4.8 \text{ USD} \text{ to } 24 \text{ USD} - 4.8 \text{ USD} = 13.2 \text{ USD to } 19.2 \text{ USD/day} \]
This profitability can vary widely depending on market conditions, particularly the Bitcoin price and electricity costs.
##### **4.3 ROI Calculation**
The return on investment (ROI) is a critical metric for miners, as it determines how long it will take to recover the initial cost of the mining hardware. The Antminer S21, priced between $7,000 and $9,000, has a relatively high upfront cost. To calculate the ROI period:
\[ \text{ROI Period} = \frac{\text{Initial Cost}}{\text{Net Daily Profit}} \]
For an S21 purchased at $8,000 with an average net profit of $16.2 per day, the ROI period would be:
\[ \text{ROI Period} = \frac{8000 \text{ USD}}{16.2 \text{ USD/day}} \approx 494 \text{ days} \approx 16.5 \text{ months} \]
This ROI period assumes stable market conditions and does not account for potential increases in difficulty or fluctuations in Bitcoin price.
