数据显示，近期比特币挖矿难度的大幅负调整极大地提振了矿工的收入。
根据最新的每周报告奥术研究 ，BTC 矿工收入仅在过去 7 天就增长了 15%。
这里的一个相关指标是“挖矿算力 ”，它衡量连接到网络的计算能力总量。
这个指标可以被认为是矿工之间存在的竞争的代表。因此，指标值的上升意味着各个矿机之间的竞争日益激烈。
BTC 区块链有一个特点，就是“出块率”（即新区块的哈希率）必须以一个恒定值为目标。但是，每当哈希率发生变化时，矿工生产区块的能力也会发生变化。
例如，哈希率的上升意味着现在网络上有更多的矿机，因此区块生产速度会更快。为了抵消这一点，比特币链增加了所谓的“挖矿难度 ”

在进行这样的调整之后，矿工发现更难对交易进行哈希处理，因此他们的速度会降低到所需的水平。
现在，这是一张图表，显示了过去一年 BTC 哈希率的趋势：

正如您在上图中看到的，比特币哈希率现在已经从 6 月份创下的历史高点下跌了 15%。
这种下降的结果是挖矿难度连续三次调整，最近一次调整是一年多来最大的调整。
