Russia’s Central Bank has acknowledged that crypto mining contributes to the ruble’s strength, though quantifying its exact impact remains difficult as much of the industry operates in gray areas. Governor Elvira Nabiullina made the statement while responding to questions about the sector’s influence on foreign exchange markets, according to a local report. The acknowledgment comes as senior Kremlin officials push to formally classify mining as an export activity in Russia’s trade accounts, which furthe ...

近期，加密货币市场震荡加剧，比特币在短暂横盘后再度下跌， 市场情绪紧张的背后，有一则与中国相关的消息，始终引起全球加密行业的关注， 据悉新疆地区的大型比特币矿场近期被集中关停，致使比特币全网算力呈现显著下降， 这一变化不仅影响矿工的运营，也在全球范围内引发了关于市场抛压、算力布局以及监管趋势的连锁讨论。 从2025年12月中旬起，事件开始引发广泛关注， 多家监测平台记录显示，比特币全网算力在24小时内出现了急剧的收缩情况， 嘉楠科技前董事长孔建平在社交平台上透露，比特币网络算力下滑大概100EHs，跌幅接近8%到10%， 用当时主流矿机的算力来进行估算，这相当于有超过40万台矿机在同一时段停止了运转。 好几个行业网站展现的趋势和这个数据是符合的，比特币总算力从大概1.1到1.2ZHs的高位下跌到了900EHs的范围。 VanEck数字资产研究负责人MatthewSigel表明，这是2024年比特币减半以后，网络算力单日下跌幅度最大的一回。 尽管新疆当地还没有对这件事发布官方说明，矿场关停的具体情况还不是很清楚， 然而时间点的重合，以及和中国矿工相关的矿池算力同步下降，让行业里大多数人觉得原因是新疆， 孔建平在 ...

Core Viewpoint - China's Bitcoin mining activities have surprisingly revived four years after a comprehensive ban, with its hash rate now ranking third globally, driven by economic incentives, local agreements, and technological realities [1][2]. Group 1: Market Share and Hashrate - As of October 2025, China's Bitcoin network hash rate has rebounded to approximately 14.1%, equating to 145 EH/s, making it the third-largest mining country after the United States (37.8% or 389 EH/s) and Russia (15.5% or 160 EH/s) [2]. Group 2: Factors Driving the Resurgence - The resurgence of Bitcoin mining in China is attributed to three core factors: 1. **Cheap Electricity**: Regions like Xinjiang, Sichuan, and Inner Mongolia offer industrial electricity prices as low as 0.2 to 0.35 RMB per kWh, significantly below the international average, creating a cost advantage for miners [4]. 2. **AI Data Centers' Unintentional Support**: The construction of AI and cloud computing data centers has led to idle facilities and power quotas, allowing local governments to tacitly permit these facilities to pivot to Bitcoin mining, thus utilizing excess electricity and generating local tax revenue [5]. 3. **High Bitcoin Prices**: Bitcoin prices surged to a historical high of $126,000 in 2025, with subsequent prices stabilizing between $80,000 and $90,000, providing substantial profit margins for miners, which incentivized their return despite regulatory risks [5][6]. Group 3: Historical Context and Global Dynamics - The expulsion of Chinese mining companies and engineers in 2021 led to their migration to the U.S., particularly Texas, where they adapted to local energy markets and became crucial in addressing the electricity demands of AI data centers [8][9]. - The irony lies in the fact that while China aimed to enhance energy security and financial sovereignty by banning mining, the displaced capacity and expertise have become vital assets for U.S. AI strategies [9]. Group 4: Regulatory Environment and Future Outlook - Despite the thriving underground mining activities, the Chinese government's ban on cryptocurrency mining remains in effect, posing risks of sudden crackdowns and penalties [11]. - Analysts suggest that as long as Bitcoin prices remain high and local governments face fiscal pressures, the ongoing "cat-and-mouse" game between regulation and market activity will continue, with the future direction remaining uncertain [11].
