At WDMS 2025, leading mining hardware manufacturer Bitmain announced its newest line of air-cooled and water cooled S23 series. Boasting an efficiency of 11 J/Th, the S23 is about 30% more efficient than the S21 Pro. The S23 Hydro outdoes all the miners on market by achieving an efficiency of 9 J/Th with an impressive hashrate of 545 Th/s.
This might make a lot of the smaller and medium-scale miners nervous as the efficiency gains have been significant compared to the S21 series launched last year. At Valuehash, we believe that power costs and running capital efficient operations is the key to a successful bitcoin mining venture. Mining is very capital intensive and unless there I an infinite money glitch like a public company issuing shares diluting investor capital, its best to not overspend on hardware. At the end of the day, investors want a meaningful return on their capital without taking outsized risks.
Our approach has always been choosing somewhat new gen but not the most cutting edge hardware as the premium is rarely worth it. Instead, we offer our clients several different uptime slabs and hosting rates associated with the uptime slabs. Gone are the days of running 24×7 without thinking about the incremental hosting costs. We position our clients to take advantage of lower cost electricity with creative arrangements to carve out a win-win situation. For example, one of our clients is able to take advantage of our 80% uptime slab and lower rates for his older S19K pro type hardware that otherwise would only be marginally profitable. This way our client is able to boost their ROI by 20% and still stack BTC meaningfully.
