The Smart Heater That Pays You with Alex Busarov
In this episode of Hosting Bitcoin, we sit down with Alex Busarov, founder of HeatBit, a company pioneering consumer-grade Bitcoin mining heaters that turn household heat into hashrate. Alex’s background spans engineering, energy systems, and entrepreneurship. His insight began with a simple realization: electricity becomes heat either way so routing that same energy through computation can produce bitcoin as a byproduct instead of pure waste. This conversation dives into the realities of home mining, the physics misconceptions around energy use, and why energy reuse may become increasingly important as halvings compress margins and chip efficiency gains slow.
