These Finland homes get free heat from bitcoin miners (as long as BTC stays above $70,000)

Finnish startup Hashlabs has deployed 30 bitcoin mining rigs that double as central heating systems, with each unit earning slightly more than its electricity cost at current BTC prices above $70,000. The setup ties mining economics directly to residential heating demand, turning what is normally a pure power expense into a revenue-generating asset as long as bitcoin holds that threshold. The model matters because it offers a hedge against mining's thin margins and energy volatility, effectively subsidizing household heat with block rewards. Watch whether BTC sustains the $70,000 level, since a sustained drop would flip the rigs from profit centers back into pure cost burdens for the homeowners.
