How to Choose Bitcoin Mining Equipment in 2025

As Bitcoin mining margins tighten in 2025, selecting the right Bitcoin mining equipment is more critical than ever. Older models like the Antminer S19 are quickly becoming obsolete in hosted environments. So, what should miners focus on when choosing new mining hardware? In this guide, we’ll explore the latest trends, compare next-gen ASIC models, and help you make the best investment decisions for long-term profitability.

Is Old Bitcoin Mining Equipment Still Profitable?

Models like the Antminer S9 are no longer viable, with their 13 TH/s output and 1300W consumption. Even the once-dominant Antminer S19 and S19j Pro, while still representing over 50% of the network, now only break even under very cheap electricity rates — $0.053/kWh and $0.062/kWh, respectively.

Yet many are still running. Why?

• Locked hosting contracts
• BTC accumulation strategies (“stacking sats”)
• Tax write-offs or offsetting losses
• Hosts taking over abandoned machines

Still, relying on outdated equipment is risky. The better strategy in 2025? Upgrade your mining fleet.

Key Considerations When Choosing Bitcoin Mining Equipment in 2025

1. Hashrate vs. Efficiency (J/TH)
   Efficiency is king in a low-margin market. The best-performing air-cooled ASICs now offer under 15 J/TH, with some models pushing 13.5 J/TH.

2. Cooling Systems
   Air-cooled ASICs remain the most popular, but hydro-cooled and immersion-ready machines are becoming more accessible and future-proof.

3. Power Requirements
   Some models (e.g. T21) require 3-phase industrial setups, while others (like S21) are optimized for plug-and-play usage at home.

4. Warranty & Manufacturer
   Established brands like Bitmain and MicroBT dominate, but newcomers like Auradine are offering impressive North American alternatives.

5. Price-to-Performance Ratio
   Higher hashrate doesn't always mean better ROI. Balance purchase cost, efficiency, and setup requirements for your operation.

3. Total Bitcoin Hashrate. The more hashing (computing) power in the network, the greater its security and its overall resistance to attack. Source
