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 mining SHA-256 algorithm-based cryptocurrencies, this powerful machine initially set benchmarks for efficiency and performance. But with evolving network difficulty, fluctuating coin prices, and rising energy costs, many miners are asking: Is the Antminer S19 Pro still profitable in 2025?
In this comprehensive analysis, we’ll break down the current profitability, specifications, and real-world mining potential of the Antminer S19 Pro—helping you make an informed decision about whether it’s a viable investment today.
Understanding the Antminer S19 Pro
The Antminer S19 Pro is a high-performance ASIC (Application-Specific Integrated Circuit) miner developed by Bitmain, a leading manufacturer in the crypto mining hardware space. It was launched to compete with other top-tier miners by offering a strong balance between hashrate and power efficiency.
- Hashrate: Up to 110.00 TH/s (±10%)
- Power Consumption: 3,250 watts
- Algorithm: SHA-256
- Release Date: June 2020
While once considered cutting-edge, the S19 Pro now faces stiff competition from newer models like the S19 XP, S21, and other next-generation ASICs. However, due to its availability on the second-hand market and relatively stable performance, it remains a common choice among small-scale and beginner miners.
Current Profitability Analysis (2025)
As of 2025, mining profitability depends heavily on three key factors: electricity cost, coin price, and network difficulty. Using an average electricity rate of $0.10 per kWh, here's how the Antminer S19 Pro performs when mining major SHA-256 coins:
Bitcoin (BTC)
Despite being the most valuable cryptocurrency, mining Bitcoin with the S19 Pro yields a daily loss of $1.32** after power costs. At a BTC price of $108,778, the miner generates approximately 0.000060 BTC per day**—not enough to cover operational expenses given current network congestion and difficulty levels.
Bitcoin Cash (BCH)
Mining Bitcoin Cash results in a slightly worse outcome, with a **daily profit of -$1.33**. Though BCH has lower network difficulty than BTC, its market value isn’t sufficient to offset electricity consumption at $0.10/kWh.
Peercoin (PPC)
Peercoin offers the best return among listed options. At a price of $0.260042 per PPC**, the S19 Pro mines around **25.80 PPC daily**, generating roughly **$6.71 in revenue. After subtracting $7.80 in power costs, this leaves a **net daily loss of $1.09**.
Fractal Bitcoin (FB)
Fractal Bitcoin currently holds negligible market value, making mining efforts practically worthless. With near-zero income and full power cost absorption, miners face a daily loss of $7.80.
📉 On average, the Bitmain Antminer S19 Pro operates at a net loss of approximately $1.09 to $1.33 per day under standard conditions in 2025.
Compared to over 200 ASIC miners tracked across mining databases, the S19 Pro ranks #165 in profitability, indicating it is no longer among the top-tier performers.
Technical Specifications
Understanding the hardware capabilities helps assess long-term viability and deployment requirements.
| Detail | Specification |
|---|---|
| Manufacturer | Bitmain |
| Model | Antminer S19 Pro |
| Release Date | June 2020 |
| Hashrate | 110.00 TH/s (±10%) |
| Power Draw | 3,250 W (±10%) |
| Efficiency | ~29.5 J/TH |
| Dimensions | 290 × 195.5 × 400 mm |
| Weight | 14.6 kg |

| Cooling Fans | 4 units |
| Network Interface | Ethernet |
| Operating Temperature | 0°C to 40°C |
| Humidity Tolerance | 10% – 90% (non-condensing) |
These specs show that while the S19 Pro is efficient for its time, newer models offer better energy-to-hash ratios—some dipping below 20 J/TH, compared to the S19 Pro’s ~29.5 J/TH.
Frequently Asked Questions
Q: Can the Antminer S19 Pro still mine profitably in 2025?
A: Under typical conditions ($0.10/kWh), the S19 Pro operates at a slight loss, making it unprofitable for most users. However, those with access to cheaper electricity (below $0.06/kWh) may break even or achieve marginal gains.
Q: What is the best coin to mine with the Antminer S19 Pro?
A: Currently, Peercoin (PPC) offers the highest relative return, though net profits remain negative at standard electricity rates. Always use up-to-date mining calculators to compare real-time returns across different SHA-256 coins.
Q: How long does it take to recover the initial investment?
A: Assuming a purchase price of $524 (its lowest recorded cost), and factoring in daily losses, there is no realistic payback period unless energy costs are drastically reduced or coin prices surge unexpectedly.
Q: Is it worth buying a used Antminer S19 Pro?
A: Only if purchased at a very low price (<$400) and used with low-cost or surplus power. Otherwise, newer models provide better ROI and longevity.
Q: Can I use the S19 Pro for cloud mining or mining pools?
A: Yes, the device supports standard Ethernet connectivity and can join major mining pools such as Slush Pool, F2Pool, or Braiins Pool. Cloud hosting services also accept S19 Pro units.
Mining Strategy Tips for Older ASICs
Even if not immediately profitable, older miners like the S19 Pro can still play a role in broader strategies:
- Cold Climate Advantage: Deploy in colder regions where cooling costs are naturally reduced.
- Off-Peak Mining: Run only during low-tariff hours if your utility offers time-of-use pricing.
- HODL Strategy: Mine and hold coins during bear markets, anticipating future price increases.
- Hybrid Setups: Combine with solar or renewable energy sources to cut power expenses.
- Pool Selection: Join low-fee or PPLNS-style pools that reward consistent contributions over time.
Final Verdict: Should You Still Use the Antminer S19 Pro?
The Bitmain Antminer S19 Pro was once a flagship model—but in 2025, it’s largely outdated for standalone mining operations relying on grid electricity priced above $0.07/kWh. With daily losses averaging around **$1.30**, continued operation without strategic optimization leads to financial drain.
However, context matters:
- For hobbyists or educational purposes, it remains a solid learning tool.
- In areas with subsidized or renewable energy, it might still contribute marginally.
- As part of diversified mining farms using mixed hardware and advanced software optimization tools, legacy units can find niche utility.
Ultimately, upgrading to more efficient models—or leveraging platforms that enhance yield through smart routing and fee optimization—offers better long-term outcomes.
