Alex Busarov on Heatbit: Bitcoin Mining Heaters and Air Purifiers

Heatbit founder Alex Busarov joins The Daily Stack to explain home Bitcoin mining with devices that reuse mining heat, including Heatbit's heaters and the new Bitair air purifier with a single chip miner. The conversation covers setup, how much heater mining can offset a power bill (30 to 100% by his estimate) versus about a dollar a month from Bitair, why heat reuse miners are the most resilient, halvings and miner margins, safety and custody choices, and Heatbit's first production run. The show also covers rate hikes, the bond market and Bitcoin as a check on war funding.

Key takeaways:
- Heatbit heaters run about 40 to 60 TH/s, and Alex says the bitcoin mined can cover 30 to 100% of the power the device uses.
- Bitair uses a single mining chip so it adds no noticeable heat, earning about $1 to $1.50 a month in a pool. It is meant as an introduction to mining, not an income source.
- Alex argues heat reuse miners pay nothing extra for electricity, so they don't need to sell their bitcoin or switch off when price falls.
- Halvings squeeze margins: Alex's example is a 60% margin dropping to about 20%, and a 40% margin going into the red.
- Heatbit does not hold users' mined bitcoin: users mine to the pool of their choice or solo mine. The company has fewer than 10 people, with Alex saying about 90% of the work is now done by AI.
