COINMINER Antminer S19 Pro 100TH Review and Profitability Calculation Estimate

·

The COINMINER Antminer S19 Pro 100TH stands as a notable entry in the world of Bitcoin mining hardware, delivering high performance and energy efficiency for serious miners. As an upgraded model in Bitmain’s renowned S19 series, this ASIC miner has attracted attention from both home operators and large-scale mining farms. However, with shifting market dynamics and rising electricity costs, its current profitability raises important questions.

This comprehensive review explores the Antminer S19 Pro 100TH’s specifications, real-world performance, and financial viability in 2025, helping you determine whether it remains a smart investment for cryptocurrency mining.

Key Specifications and Design Features

Manufactured by Bitmain, the Antminer S19 Pro is built on a custom-designed chip architecture optimized for the SHA-256 algorithm, making it ideal for mining Bitcoin (BTC) and compatible coins like Bitcoin Cash (BCH) and Bitcoin SV (BSV).

Here are the core technical details:

The unit’s compact design and efficient thermal management make it adaptable for various environments—from residential basements to industrial data centers.

Performance and Mining Capabilities

The Antminer S19 Pro 100TH delivers consistent performance under optimal conditions. Thanks to its advanced firmware, setup is straightforward, and the intelligent control system ensures stable operation even during prolonged use.

Its high hashrate allows users to remain competitive in the Bitcoin network, especially when connected to major mining pools such as F2Pool, Poolin, or Slush Pool. While originally capable of generating over $50 in daily revenue during peak Bitcoin prices and lower network difficulty, current market conditions have significantly altered that outlook.

Today, mining profitability hinges heavily on two primary factors: electricity cost and network difficulty. With increasing global adoption and more powerful miners entering the network, competition has intensified.

Profitability Analysis: Is the S19 Pro Still Viable?

Based on current estimates using an electricity rate of $0.10 per kWh, the financial outlook for the Antminer S19 Pro is less optimistic:

Estimated Power Costs

Estimated Revenue (Before Costs)

Net Profit After Electricity Costs

At these figures, the miner operates at a consistent loss and would never achieve payback under the assumed conditions. Even with a contract duration estimated at 256 days, returns remain negative.

Disclaimer: These calculations are based on real-time data and standard assumptions. Actual results may vary due to fluctuations in Bitcoin price, network difficulty, pool fees, and local electricity rates.

Market volatility means today’s unprofitable miner could become viable again if BTC surges or energy costs drop. However, as of now, the S19 Pro struggles to compete against newer models like the S21 or WhatsMiner M50S.

Frequently Asked Questions (FAQ)

Q: Can the Antminer S19 Pro still mine Bitcoin profitably?
A: Under average electricity rates ($0.10/kWh), the S19 Pro runs at a net loss. Profitability may return only with cheaper power (<$0.06/kWh) or significant increases in Bitcoin's price.

Q: What cryptocurrencies can the S19 Pro mine?
A: It mines all SHA-256-based coins, including Bitcoin (BTC), Bitcoin Cash (BCH), Bitcoin SV (BSV), Peercoin (PPC), and Curecoin (CURE).

Q: Is the noise level acceptable for home mining?
A: At 75 dB, it’s comparable to a loud vacuum cleaner. While usable in homes, it should be placed in a well-ventilated, isolated area to minimize disturbance.

Q: How long does the Antminer S19 Pro last?
A: With proper maintenance and cooling, most units last 3–5 years. However, performance degradation typically begins after 2 years.

Q: Does it come with a power supply?
A: No—the APW12 power supply is sold separately and required for full operation.

Q: Where should I place my miner for best performance?
A: Ensure ambient temperatures stay between 5°C and 40°C, with good airflow and low humidity. Avoid enclosed spaces without ventilation.

Final Verdict

The COINMINER Antminer S19 Pro 100TH was once a flagship device that set benchmarks in efficiency and performance. While technically robust and well-engineered, its current economic feasibility is limited under typical operating conditions.

For new investors, newer models offer better efficiency and faster payback periods. However, for experienced miners with low operational costs or strategic use cases (like heat reuse), the S19 Pro can still play a role in a broader mining strategy.

Always perform up-to-date calculations using live data from trusted mining calculators before purchasing any hardware. The crypto mining landscape evolves rapidly—what’s unprofitable today might rebound tomorrow.
