If you're going to mine bitcoin, you're going to need a mining machine. In this blog post, we profile some of the best Bitcoin mining machines available in 2026.


Mining can be a great way to get bitcoin exposure, BUT it's also highly competitive and can be risky. Choosing the right machine model can make all the difference.

Our most recent quarterly Bitcoin Mining Economics Projections Report shows that future-proofing against network difficulty growth through better efficiency (J/TH) will be crucial for miners as global Bitcoin hashrate adoption continues around the world.

Here are the models we cover for this year's best Bitcoin mining machines:

  1. Bitmain Antminer U3S23H (Hydro)
  2. MicroBT Whatsminer M79S (Hydro)
  3. Canaan Avalon A1566HA (Hydro)
  4. MicroBT Whatsminer M70S+ (Air)
  5. Canaan Avalon A16 XP (Air)
  6. Bitmain Antminer S21 XP (Hydro)
  7. MicroBT Whatsminer M66S (Immersion)
  8. Canaan Avalon A1566i (Immersion)
  9. Bitdeer Sealminer A2 Pro (Air)
  10. Auradine Teraflux AT2880 (Air)

Note: Model selection is not driven by mining economics alone. Our framework considers efficiency (J/TH), form factor relevance (air, hydro, immersion), manufacturer track record, serviceability, and expected deployment scale across institutional fleets. Several models are newly announced or early in production, meaning shipment volumes and long-term reliability data are still limited; performance metrics should therefore be viewed as indicative rather than fully proven.

Including pre-deployment hardware reflects where capital and demand are moving into 2026, while recognizing that real-world uptime and support quality will ultimately separate winners from marketing claims.
