比特币挖矿难度在 9 月份有所下降，导致比特币哈希率大幅上升。它创下了历史新高，每小时的区块产量也很高。现在，矿工们开始只带来他们新的、更高效的矿机。这导致人们预测挖矿难度将在未来一周出现大幅调整。
12% 难度调整
随着市场进入新的一个月，比特币哈希率创下了每秒 260 exahashes 的历史新高。在同一周内，矿工收入也大幅上涨，导致此时增长 10.3%。区块生产率增长了 8.4%，达到每小时 6.45 个新区块。对于比特币矿工来说，这是美好的一周，但正如 2022 年迄今为止的情况一样，预计这种情况不会持续下去。
该行业的预测称，下周比特币挖矿难度预计将调整 12%。如果发生这种情况，这将是 2022 年迄今为止难度最高的调整，但许多因素使这成为可能的结果。

此外，世界各地的气温开始下降，这意味着矿工可以将更多的能源投入到他们的活动中。所有这些都将有助于下周进行相当大的难度调整。
比特币矿工应该做好准备
比特币矿工的利润率在熊市中遭受了极大的损失。由于 BTC 的价格跌至接近生产价值的水平，矿工很难从其运营中获利，而预期的挖矿难度调整进一步威胁到他们的利润率。
该领域的竞争继续加剧，因此尽管上周矿工收入有所增加，但并没有转化为这些矿工的利润。 Glassnode 估计矿工花费 18,300 美元来开采一个比特币。在低于 20,000 美元的价格下，矿工几乎看不到他们开采的每个 BTC 有 1,000 美元的利润率。
尽管如此，矿工们继续通过购买新设备和启动新地点来扩大生产能力。据报道，公共比特币矿商 Marathon Digital 在 9 月份开采的 BTC 比 8 月份多 100%。该矿工的数据显示，当月开采了 360 个 BTC，使其 BTC 总持有量达到 10,670 个 BTC（2.15 亿美元）。
