Bitcoin miners just hit a profitability wall that's making history for all the wrong reasons. Industry analysts are flagging this as the toughest margin squeeze these operations have ever faced. The numbers don't lie—mining rewards keep getting slashed while operational costs refuse to budge. Energy bills? Through the roof. Hardware depreciation? Accelerating. Network difficulty? Climbing relentlessly. Smaller mining outfits are feeling the heat first, but even the big players with economies of scale are watching their bottom lines bleed. Some operations are already pulling the plug on less efficient rigs just to stay afloat. This isn't just another cyclical dip—the data suggests we're witnessing a structural shift in mining economics that could reshape the entire sector.
