The Bitmain Antminer S19 Pro remains one of the most recognized ASIC miners in the cryptocurrency mining industry since its release in June 2020. Designed for SHA-256 algorithm mining, this high-performance machine delivers a maximum hashrate of 110.00 TH/s while consuming 3,250 watts of power. While once a top-tier mining rig, its profitability in 2025 depends heavily on electricity costs, coin valuations, and network difficulty.
This in-depth analysis explores the current mining performance, cost-efficiency, and real-world profitability of the Antminer S19 Pro—helping miners determine whether it still holds value in today’s competitive landscape.

Current Mining Profitability (2025)
As of 2025, the profitability of the Bitmain Antminer S19 Pro has significantly declined due to increased network difficulty, aging hardware efficiency, and fluctuating cryptocurrency prices. Using an average electricity rate of $0.10 per kWh, here's how the miner performs across major SHA-256 coins:
Bitcoin (BTC) Mining
At a Bitcoin price of $108,778**, the S19 Pro generates approximately **$6.48 per day in revenue. After subtracting $7.80** in daily electricity costs, this results in a **net loss of $1.32 per day.
Bitcoin Cash (BCH) Mining
With BCH priced at $478.58**, daily income drops to around **$6.47, yielding a daily loss of $1.33 after power expenses.
Peercoin (PPC) Mining
Peercoin offers slightly better returns at $0.26 per coin**. The miner earns about **$6.71 per day, translating to a daily deficit of $1.09—the closest to breakeven among listed options.
Fractal Bitcoin (FB) Mining
Fractal Bitcoin, with negligible market value ($0.00**), generates no meaningful income, leading to a full **$7.80 daily loss—equivalent to total power cost.
📌 At current rates, the Antminer S19 Pro operates at a negative daily profit margin, making it unprofitable for most individual miners relying on grid electricity priced above $0.08/kWh.
Among all ASIC miners tracked by performance comparison platforms, the S19 Pro ranks around #165 in profitability, indicating limited viability unless paired with ultra-cheap or renewable energy sources.
Key Factors Affecting Profitability
Several variables influence whether older ASICs like the S19 Pro remain viable:
Electricity Cost
This is the single most critical factor. For the S19 Pro to break even:
- It requires electricity priced below $0.07/kWh.
- Locations with subsidized industrial power or off-grid solar setups may still find marginal use cases.
Mining Pool Efficiency
Joining high-efficiency pools with low downtime and transparent payout systems helps maximize returns—even from underperforming hardware.
Hardware Longevity & Maintenance
After four years of operation, wear and tear on fans, power supplies, and chips can reduce effective hashrate. Regular maintenance is crucial to sustain performance.

Frequently Asked Questions (FAQ)
Is the Antminer S19 Pro still profitable in 2025?
No—not under standard conditions. With electricity at $0.10/kWh, it generates a daily loss of approximately **$1.09 to $1.33**, depending on the coin mined. Profitability is only possible with very low electricity costs (<$0.06/kWh) or in regions with tax incentives and free cooling.
What coins can I mine with the Antminer S19 Pro?
The S19 Pro supports any cryptocurrency using the SHA-256 algorithm, including:
- Bitcoin (BTC)
- Bitcoin Cash (BCH)
- Peercoin (PPC)
- Syscoin (SYS)
- Namecoin (NMC)
Mining profitability varies widely based on market price and network difficulty.
How much does it cost to run the S19 Pro daily?
At 3.25 kW and an electricity rate of $0.10/kWh, the daily power cost is:
3.25 kW × 24 hours × $0.10 = **$7.80 per day**
This must be deducted from gross mining income to determine net profit or loss.
Can I mine Peercoin profitably with the S19 Pro?
Mining Peercoin yields about 25.80 PPC per day (~$6.71), but after power costs, you still face a **$1.09 daily deficit**. While PPC has lower network difficulty than Bitcoin, its low market value prevents profitability at current levels.
What is the lifespan of an Antminer S19 Pro?
With proper cooling and maintenance, the S19 Pro can last 4–6 years in continuous operation. However, efficiency degrades over time, especially if operated in dusty or hot environments.
Where should I buy a used Antminer S19 Pro?
Used units are available through online marketplaces and mining equipment resellers. Always verify:
- Operational hours
- Firmware version
- Presence of replaced parts
- Noise and thermal performance
Purchasing from reputable sellers reduces the risk of buying damaged or throttled hardware.

Final Verdict: Should You Still Use the S19 Pro?
The Bitmain Antminer S19 Pro was once a flagship mining machine—but in 2025, it serves more as a cautionary tale than a profitable asset for most users.
Unless you have access to extremely low-cost electricity (below $0.06/kWh), free infrastructure, or are using it for educational purposes, operating the S19 Pro results in financial losses.
However, for large-scale operators managing hundreds of units with optimized logistics and energy sourcing, repurposing older models like the S19 Pro for alternative SHA-256 coins or donation-based mining may still offer niche utility.
For individual miners, upgrading to newer models such as the Antminer S21 Hyd, S21 Pro, or energy-efficient alternatives offers significantly better returns and future-proofing against rising energy costs and network adjustments.
In summary: The Antminer S19 Pro is no longer a profitable standalone investment—but understanding its limitations helps inform smarter decisions in today’s evolving mining ecosystem.
