The Bitmain Antminer S19K Pro is a high-performance ASIC miner introduced in July 2023, designed for mining SHA-256 algorithm-based cryptocurrencies. With a robust hashrate of up to 134.00 TH/s and a power consumption of 3,264 watts, this device targets serious miners seeking efficiency and reliability in their operations.
This comprehensive guide explores the real-world profitability, technical specifications, and mining potential of the Antminer S19K Pro—offering data-driven insights to help you make informed investment decisions.
Understanding the Profitability of the Antminer S19K Pro
Mining profitability depends on several key factors: cryptocurrency market price, network difficulty, electricity cost, and hardware efficiency. The Antminer S19K Pro delivers solid performance across these metrics, particularly when mining alternative SHA-256 coins like Peercoin (PPC).
At an electricity rate of $0.10 per kilowatt-hour**, the daily operational cost stands at **$7.83. Here’s how its earnings break down across major SHA-256 cryptocurrencies:
Mining Peercoin (PPC)
- Coin Price: $0.260476
- Daily Revenue: $8.19
- Daily Profit: $0.35
- Coins Mined Per Day: 31.43 PPC
Peercoin currently offers the most profitable mining opportunity for the S19K Pro due to lower network competition and consistent block rewards.
Mining Bitcoin (BTC)
- Coin Price: ~$108,966
- Daily Revenue: ~$7.89
- Daily Profit: $0.06
Despite Bitcoin's high market value, mining it with this model yields minimal profit due to extreme network difficulty and intense competition from large-scale mining farms.
Mining Bitcoin Cash (BCH)
- Coin Price: ~$481.89
- Daily Revenue: ~$7.87
- Daily Profit: $0.03
Bitcoin Cash offers slightly better returns than Bitcoin but still lags behind Peercoin in terms of net gain.
Mining Fractal Bitcoin (FB)
- Coin Price: $0.00 (not actively traded)
- Daily Revenue: ~$0.00
- Daily Loss: -$7.83
Fractal Bitcoin currently provides no financial return, making it an unviable option unless future price developments occur.
At current rates, the Antminer S19K Pro generates approximately $0.35 in daily profit when mining Peercoin—the most favorable option among SHA-256 coins.
Among all ASIC miners tracked on performance comparison platforms, the S19K Pro ranks as the 94th most profitable miner, reflecting its niche viability rather than top-tier dominance.

Where to Mine Peercoin Profitably
Peercoin remains one of the few SHA-256 coins where individual miners can still achieve positive returns using consumer-grade ASICs like the S19K Pro.
To get started:
- Join a reputable Peercoin mining pool such as PPCMiner or Hashrate Market.
- Configure your miner using standard stratum protocols via Ethernet.
- Monitor output through pool dashboards and adjust settings for optimal hashrate stability.
Due to lower hash competition compared to Bitcoin, Peercoin networks allow smaller operators to earn consistent block rewards—especially when using efficient hardware.
Additionally, Peercoin supports both proof-of-work and proof-of-stake mechanisms, which helps stabilize inflation and maintain long-term coin value—a promising sign for investors.
Frequently Asked Questions (FAQ)
What is the daily profit of the Antminer S19K Pro?
At $0.10/kWh electricity cost and current market prices, the miner earns about **$0.35 per day** when mining Peercoin—the most profitable option available.
Is the Antminer S19K Pro still worth buying in 2025?
While not a top-tier performer for Bitcoin mining, it can be viable for mining less competitive SHA-256 coins like Peercoin—especially if purchased below $750.
How much electricity does the S19K Pro use?
It consumes 3,264 watts per hour, translating to roughly 78.3 kWh per day. At $0.10/kWh, that results in a daily power cost of **$7.83**.
Can I mine Bitcoin profitably with the S19K Pro?
Mining Bitcoin directly yields only about **$0.06 in daily profit**, making it nearly break-even after electricity costs. It's generally not recommended unless energy costs are below $0.05/kWh.
What is the noise level of this miner?
The device operates at 75 dB, similar to a loud vacuum cleaner. It should be placed in a dedicated space or sound-dampened enclosure to minimize disturbance.
Where can I buy the Bitmain Antminer S19K Pro?
The miner is available through authorized distributors, second-hand markets like eBay or MinerMarket, and select cryptocurrency equipment retailers—though availability may vary by region.
