外媒称,比特币网络正接近出现 17 年来首次年度挖矿难度回落,但这一结果目前仍未最终确定。到今年底前,网络预计还会进行 5 轮自动调整,如果币价回升、部分矿机重新上线,年末难度仍可能高于 2025 年水平。

矿工成本高于现货价格

报道援引 onchainmind 的估算称,目前挖出 1 枚比特币的平均成本约为 7.61 万美元,而比特币现货价格徘徊在 6.5 万美元附近,矿工整体已处于亏损区间。

文章称,今年以来比特币价格累计下跌约 26%,行业收入也明显减少,促使部分矿工关闭设备。美国得州夏季高温,以及 2 月风暴带来的电力成本压力,也加快了矿机关停。

  • 挖矿平均成本约为 7.61 万美元
  • 比特币现货价格约为 6.5 万美元
  • 全网算力较峰值回落近 20%

难度下调对应矿工出清

在算力回落后,比特币网络会通过自动调整机制下调挖矿难度,以降低剩余矿工的竞争压力。文章认为,这说明网络仍在按既定机制运行,低成本矿工的经营压力会有所缓解。

报道还提到,链上指标 Puell Multiple 已降至较低分位区间。按其说法,这通常对应矿工承压、低效产能出清的阶段。过去类似阶段,往往出现在市场接近阶段性底部时。

矿企越来越依赖 AI 业务

不过,文章也强调,当前年度难度回落仍未成为定局。即便后续几轮调整后难度重新回升,这一轮变化也已显示出矿业格局正在改变。

报道认为,比特币网络可以通过难度调整缓冲矿工利润压力,但矿企自身的财务稳定性,正越来越多受到 AI 相关算力租赁业务影响。部分矿业公司的经营表现,已不再只取决于币价和区块奖励。
