On Dec. 23, the company advertised a bundled sale for four S19 XP+ Hydro units paired with an ANTRACK V2 container, implying a unit price of roughly $4/TH/s for the 19 J/TH model.

The discount followed a November auction-style sale for the air-cooled S19k Pro, a 23 J/TH machine, which opened with a starting bid of $5.5 per terahash.

As of Dec. 22, Bitmain was quoting prices as low as $3/TH/s for S19e XP Hydro and 3U S19 XP Hydro units, and $4/TH/s for S19 XP+ Hydro machines.

Even newer-generation hardware has seen meaningful reductions, with S21 Immersion units priced around $7/TH/s and S21+ Hydro machines offered at roughly $8/TH/s before coupons.

Does anyone know what they were charging before? Is this a 20% discount or a 50% discount?
