Post-halving, machines above 25J/TH are increasingly uneconomical at current difficulty unless paired with very cheap power. Your 2025 hardware decisions define profitability for the next 18–24 months.

Bitmain Antminer S21 — ~13.5 J/TH

The current efficiency gold standard for air-cooled deployments. Widest global service and spare-parts network. The S21 XP Hydro variant works with liquid cooling at our Russia hydro-cooled facility.

MicroBT Whatsminer M60 — ~15 J/TH

Strong reliability track record. Particularly well-suited to cold-climate facilities — consistent performance at our Russia air-cooled operation where ambient temperatures reduce thermal load.

Canaan Avalon A15

Competitive efficiency, lower acquisition price. Gaining traction with cost-sensitive institutional buyers at scale. Our on-site teams are certified across all three major brands.

All Coinfast hosting facilities support 240V air-cooled deployment. Machines must draw 2.8KW+ with valid import docs. Request a quote for your fleet.
