Bitcoin recovered from its 2018 decline, climbing from approximately $3,400 early in 2019 to above $13,000 in June and July. The recovery materially improved mining margins.

The archived model estimates electricity at $0.04–0.05 per kWh and a shutdown or breakeven BTC price of roughly $3,500–4,500. At the mid-year peak, gross mining margins were estimated at 65–70%.

The industry introduced 7 nm miners including the Antminer S17/T17 and WhatsMiner M20S families, delivering around 50–72 TH/s and improved energy efficiency of roughly 40–45 J/TH.

As global Bitcoin network hashrate exceeded 100 EH/s, TerraHash's archive describes procuring a new ASIC fleet and lifting managed computing capacity beyond 100 PH/s.

Hong Kong's feed-in tariff program paid approximately HK$4–5 per kWh for qualifying distributed solar generation, higher than typical mining electricity procurement costs.

TerraHash's archived strategy combines exporting rooftop solar electricity to the grid with lower-cost direct or off-grid electricity for computing operations, aiming to stabilize cash flow and reduce blended energy expenditure.

The archived project describes a dynamic hedging approach intended to reduce exposure to changing Bitcoin prices and network difficulty.

The model combines relatively stable rooftop-solar tariff revenue with more volatile Bitcoin mining returns. This was presented as a way to support fleet cash flow during price declines; investment outcomes are not guaranteed.
