Did you know you’d need roughly 1,850 Bitmain Antminer S21XP 270 TH/s units, churning at a collective 500 PH/s, to mine 1 full Bitcoin per day in today’s competitive landscape (assuming current network hashrate around 900 EH/s and block rewards)? That’s a massive farm, but OneMiners makes it achievable without the hassle of building it yourself, leveraging their 80 EH/s powerhouse operations expanding to 220 EH/s by 2027.
Originally launched in October 2024, the S21XP continues to impress well into 2025 with its groundbreaking 13.5 J/TH efficiency and powerful 270 TH/s performance. OneMiners’ exclusive unboxing video showcases why this flagship still dominates SHA-256 mining for Bitcoin and beyond. Despite its wide availability, OneMiners’ hands-on demo highlights seamless integration across their six U.S. facilities, delivering $0.04/kWh electricity rates, 95%+ uptime, zero hosting fees, and industry-leading seven-year warranties, proving that even in 2025, the S21XP remains a miner built for the future.
With the S21XP now at a sharp $4,199 (currently 14% off), OneMiners turns that “dream farm” into reality: plug in, profit big, and scale effortlessly from their 1,200 MW capacity growing to 3,500 MW, proving why they’re the go-to for miners eyeing dominance in American crypto by 2027. In this article, we’ll go deeper into this miner.
