I went through the same process a few weeks back when upgrading my rig. There’s a lot of variation in price depending on whether you're buying directly, second-hand, or through resellers. What helped me get a clear picture was a breakdown on captainaltcoin that focused on
bitcoin mining machine price 2025 and how it compares across models. For example, the Hashivo B2 is priced high, around $4,900, but it gives you 800 TH/s—though it also draws 11,000W. The Antminer S21 Hyd sits in the $3,300 range and delivers 335 TH/s, which offers a more efficient power-to-performance ratio. But if budget is tight, the Hashivo B1 might be worth a look—about $2,200, solid 500 TH/s output, and quieter operation thanks to hydro cooling. That article also broke down how pricing is expected to shift post-halving and which models are expected to hold resale value.
