中国于 2021 年禁止比特币开采的禁令对该领域产生了最大的影响之一。在此背景下，随着世界矿业之都的哈希率降至几乎为零，数字资产的价格呈大幅下跌趋势。然而，在全面禁令宣布不到一年后，该地区的采矿业又开始复苏，这表明中国为阻止该国的采矿活动所做的所有努力都失败了。
在最长的时间里，中国的哈希率下降幅度如此之大，以至于成为哈希率最低的地区之一。这种情况将在 2021 年底发生变化，届时该地区会记录更多的哈希率。此前有人猜测，一些比特币矿工仍留在中国，但秘密开展业务。

鉴于来自该国的哈希率数量，这些秘密行动现在变得越来越大。到 2022 年第二季度，中国正在慢慢恢复其在世界矿业领域的主导地位。它目前占所有哈希率的 21%，仅次于占总哈希率 38% 的美国。
哈萨克斯坦、加拿大和俄罗斯等国家的超越堪称重大。鉴于目前在该地区以外记录的哈希率是非法生产的，这将表明中国在挖矿领域的主导地位。

尽管如此，尽管目前的哈希率因禁令而下降而大幅增长，但这并没有改变一个事实，即它仍然明显低于该地区在禁令之前产生的水平。现在比该国仍允许挖矿时的哈希率低 46％。
关于为什么中国未能充分执行去年宣布的比特币挖矿禁令，有很多猜测。已经提出了许多因素作为其背后的原因。
最突出的因素之一是该国幅员辽阔。即使政府全力支持杜绝该地区的所有采矿活动，但它有如此多的土地需要覆盖，这一事实始终对它不利。这也意味着矿工能够将他们的业务隐藏在政府可能需要数月甚至数年才能发现的地方。

其中一些地方可能非常偏远，政府甚至可能不知道它们的存在。这是因为大型挖矿作业通常需要大量空间，而这些偏远地区为矿工提供了他们所需的空间，同时还努力使他们的挖矿农场保持匿名。

该地区目前搁浅的能源资源数量也无济于事。由于这种能源否则会被浪费掉，因此当地官员宁愿让矿工使用这些能源并从这些搁浅的能源资源中获得收入，也不愿让它被浪费掉。因此，比特币挖矿在该地区继续蓬勃发展。
这表明完全禁止比特币开采是不可能的。即使在政府对其公民拥有如此广泛控制的地方，仍有人想方设法继续经营，因此阻碍了所有禁止采矿的努力。
