Bitcoin miners face deepening margin squeeze as revenue falls below production costs

Bitcoin miners are grappling with a severe financial squeeze as their revenue has dipped below the cost of production, leaving an estimated 20% of them operating at a loss. This is causing operational stress at the network level, which could lead to a reduction in the network's hash rate, impacting Bitcoin's security and transaction processing speed. The situation underscores the volatile nature of cryptocurrency mining, where market price fluctuations can dramatically affect large-scale operations, hinting at potential shifts in the mining ecosystem.
