Technical Specifications Overview

The Antminer S19 was launched in May 2020 and quickly gained traction due to its balance of hashrate, power efficiency, and durability. Below are the core specifications that define its performance:

These specs position the S19 as a reliable workhorse for continuous operation—provided that electricity costs and ambient conditions are optimized.

Real-Time Profitability Analysis (2025)

As of July 4, 2025, the Bitmain Antminer S19 (95TH/s) is operating at a loss under standard assumptions. With an average electricity cost of $0.10 per kWh, here's a breakdown of daily, monthly, and yearly profitability:

💵 Income

⚡ Electricity Cost

💰 Net Profit

At first glance, these numbers suggest unprofitability—but context matters. The miner’s output depends heavily on Bitcoin’s price, network difficulty, and local energy rates. In regions with cheaper electricity (e.g., below $0.06/kWh), the S19 can still break even or generate modest returns.

Mineable Cryptocurrencies

While primarily used for Bitcoin (BTC) mining, the Antminer S19 is also compatible with other SHA-256-based cryptocurrencies:

Most miners choose to mine Bitcoin directly or through pools that auto-convert hashpower into BTC. Some leverage platforms like NiceHash to dynamically switch to the most profitable coin at any given moment.

Energy Efficiency: Why It Matters

With an efficiency rating of 34.21 J/TH, the S19 sits mid-tier among modern ASIC miners. Newer models like the S19 XP or Whatsminer M50 offer better efficiency (closer to 20 J/TH), making them more suitable in high-electricity-cost environments.

However, the S19’s proven reliability and widespread availability keep it relevant. For users with access to low-cost power or surplus renewable energy (like solar or hydro), even slightly inefficient hardware can remain economically viable.

Efficiency directly impacts long-term profitability—especially as network difficulty increases over time.

Frequently Asked Questions

Is the Bitmain Antminer S19 (95TH/s) profitable in 2025?

As of mid-2025, the Antminer S19 (95TH/s) generates a daily net loss of approximately **$0.84**, assuming $0.10/kWh electricity costs. However, profitability varies by region—miners in areas with subsidized or renewable energy may still achieve break-even or small gains.

What is the hashrate of the Bitmain Antminer S19?

The device delivers a maximum hashrate of 95 terahashes per second (TH/s) when running on the SHA-256 algorithm, ideal for Bitcoin mining.

How much electricity does the S19 consume daily?

At 3,250 watts and continuous operation, the Antminer S19 consumes about 78 kWh per day. At $0.10/kWh, this equals **$7.80 in daily electricity costs**.

Can I mine Bitcoin Cash with the Antminer S19?

Yes. Since Bitcoin Cash uses the same SHA-256 algorithm, the S19 is fully compatible and can be configured to mine BCH through supported pools.

What is the lifespan of an Antminer S19?

With proper ventilation, dust control, and regular maintenance, most units last between 3 to 5 years under continuous operation. Fan replacements every 1–2 years are recommended to maintain cooling efficiency.

Where can I buy a Bitmain Antminer S19?

While official Bitmain channels may have limited stock, third-party vendors in Hong Kong and North America occasionally carry new or refurbished units. Always verify warranty status and authenticity before purchasing.
