Your Heater Could Be Mining Bitcoin Right Now
Show notes
Alex Busarov of Heatbit joins The Daily Stack to explain how Bitcoin miners can double as home heaters and air purifiers, putting mining heat to use instead of wasting it. The conversation covers Heatbit's origin story, the new single chip Bitair purifier, how setup works, and why heat reuse miners may be the most resilient and decentralized miners as halvings squeeze margins. They also discuss product safety and custody choices, Heatbit's small AI-assisted team, and using mining as a way to introduce people to Bitcoin.

Key takeaways:
- Alex says Heatbit heaters can cover anywhere from 30 to 100% of the power the device uses, running at roughly 40 to 60 terahashes.
- The Bitair air purifier uses a single mining chip so it produces no noticeable heat and earns about a dollar to a dollar and a half a month in a pool. It is meant as an introduction to mining.
- Alex argues large miners turn off machines and sell their Bitcoin when prices fall, and many are moving to AI, while home heat reuse miners have no extra energy cost and no need to sell.
- Bitcoin mined on Heatbit devices goes to the user's chosen pool or directly to them when solo mining. Heatbit does not hold it.
- Heatbit has fewer than 10 people, with Alex saying about 90% of the work is now done with AI.
