The Bitmain Antminer S19 (95Th) is a popular ASIC miner designed for the SHA-256 algorithm, primarily used for Bitcoin mining. With a hash rate of 95 terahashes per second (TH/s), it represents a significant piece of mining hardware. However, its profitability is influenced by various dynamic factors, including Bitcoin's price, network difficulty, and electricity costs. This analysis provides a clear overview of its current performance and key considerations for potential miners.
Real-Time Profitability Analysis
Based on real-time data, here is a detailed breakdown of the Antminer S19 (95Th)'s current financial performance. These figures assume an electricity cost of $0.10 per kWh.
| Metric | Day | Month | Year |
|---|---|---|---|
| ⛏️ Income | $5.58 | $167.36 | $2,036.17 |
| ⚡ Cost | $6.24 | $187.20 | $2,277.60 |
| 💰 Profit | -$0.66 | -$19.84 | -$241.43 |
This snapshot indicates that at current market conditions, the operational costs of running this miner slightly exceed the daily income it generates, resulting in a marginal loss.
Solo Mining Probability
For those considering solo mining, the odds of successfully mining a block and claiming the full reward are statistically low:
- Daily Chance: 1 in 63,989
- Monthly Chance: 1 in 2,102
- Yearly Chance: 1 in 175
This highlights why most individual miners join a mining pool to receive smaller, more frequent rewards.
Key Bitcoin Network Statistics
The Bitcoin network's state is crucial for forecasting miner profitability. Key metrics to watch include:
- Next Difficulty Adjustment: In approximately 8 days.
- Estimated Change: An increase of 4.86% is projected.
- Blocks Remaining: 1233 (38.84% of the epoch complete).
- Average Block Time: 9 minutes.
Network difficulty, which adjusts approximately every two weeks, directly impacts how much mining power is required to earn Bitcoin. A rising difficulty means more competition and lower rewards for the same amount of hash power.
Detailed Miner Performance Overview
The Antminer S19 (95Th) is currently generating an estimated daily income of $5.58. After deducting electricity costs of $6.24, this results in a daily loss of $0.66. This translates to a monthly loss of $19.84. It's important to understand that these figures are highly sensitive to the price of Bitcoin. For instance, if Bitcoin's price were to rise to $163,482, the daily profit could become positive, estimated at around $2.13 per day.
The most critical variable for most miners is the cost of electricity. At a rate of $0.10 per kWh, the miner operates at a slight deficit. Securing a lower electricity rate is often the key to achieving profitability with older generation hardware.
Technical Specifications of the Antminer S19
The Antminer S19 (95Th) is engineered for performance and reliability, incorporating several advanced features:
- ASIC Chip: Utilizes Bitmain's proprietary second-generation 7nm BM1397 chip, designed for enhanced computational efficiency and stability.
- Thermal Management: A robust dual-fan cooling system with auto-adjusting speeds ensures optimal operating temperatures, minimizing downtime due to overheating.
- Firmware: Advanced firmware optimizes chip efficiency and significantly reduces hash rate fluctuations.
- Design: Its compact and durable form factor allows for high-density deployments in data centers without sacrificing essential airflow.
- Remote Management: The unit supports oversight through Bitmain's Antminer Management Tool, enabling operators to monitor and manage multiple units seamlessly.
The SHA-256 Algorithm Explained
SHA-256 is the foundational cryptographic hash algorithm that secures the Bitcoin network.
- Function: It is a one-way function that converts input data of any size into a fixed-size, unique 256-bit output (hash).
- Collision Resistance: A key feature is its extreme resistance to collisions, making it computationally infeasible to find two different inputs that produce the same hash output. This guarantees the integrity of transactions on the blockchain.
- Proof-of-Work: In Bitcoin mining, SHA-256 serves as the proof-of-work mechanism. Miners compete to solve a complex mathematical puzzle by finding a hash that meets a certain target. The first miner to solve the puzzle earns the right to add the new block to the blockchain and is rewarded with new bitcoins and transaction fees.

Frequently Asked Questions
Is the Antminer S19 (95Th) profitable in 2024?
Based on current data and an electricity cost of $0.10/kWh, the S19 (95Th) operates at a slight loss. Profitability is entirely dependent on securing very low electricity costs or a significant rise in Bitcoin's price. Using hosted mining services with lower power rates can often flip this model into profitability.
What is the most important factor for mining profitability?
Electricity cost is the single most important factor for miners, especially those using older-generation hardware like the S19. Even a small reduction in the cost per kWh can dramatically change the profit margin, more so than minor fluctuations in Bitcoin's price.
Should I consider solo mining with one Antminer S19?
Solo mining with a single S19 is not advisable. The probability of successfully mining a block alone is extremely low (e.g., 1 in 2,102 for a month). Joining a mining pool provides smaller but consistent and predictable payouts, which is essential for covering ongoing operational costs.
How does network difficulty affect my earnings?
Network difficulty measures how hard it is to find a new block. When difficulty increases, your miner's share of the total network hash rate decreases, meaning you earn less Bitcoin over time. This is a constant dynamic that all miners must account for in their long-term calculations.
What is the advantage of Bitmain's 7nm BM1397 chip?
The 7nm design allows for more transistors to be packed into a smaller space, leading to greater computational power (hash rate) while consuming less energy. This improved efficiency (measured in J/TH) is what separates newer models from older ones and is vital for maintaining profitability.
Can I manage an Antminer S19 remotely?
Yes, the Antminer S19 supports remote management through Bitmain's web-based interface and management tools. This allows you to monitor the miner's status, hash rate, temperature, and fan speeds, and to reboot or configure it from anywhere with an internet connection.
