CoinEx News: JPMorgan estimates Bitcoin's average production cost — what it costs miners in electricity and hardware to mint one coin — at roughly $78,000, and says the spot price has stayed below that level for five straight months into June 2026, leaving about 20% of miners operating at a loss. With BTC near $63,000 after a hawkish Federal Reserve meeting, the gap between price and cost is widening, and JPMorgan expects higher-cost operators to keep switching off rigs, weighing on network hash rate.
