Bitcoin mining

Cathedra Bitcoin (CBTTF) announced its Q3 2025 financial results, reporting C$5.5 million in revenue and a net loss of C$0.8 million, a C$3.2 million improvement year-over-year. Subsequent to the quarter, Cathedra executed a 30:1 share consolidation and completed a 15 MW data center in Kentucky, increasing power capacity by 50%.

With rising energy costs, using cryptocurrency mining to heat homes is gaining traction. Bitcoin mining generates significant heat, often wasted, that can be repurposed. While some companies already offer Bitcoin mining heaters, skeptics question the efficiency and economic viability for individual households, citing specialized mining hardware. However, proponents argue recapturing computational heat makes sense in various settings, and cite real-world applications where crypto mining offsets heating costs. Further research is needed to assess its scalability, environmental impact, and integration with existing energy systems.
