美国和加拿大在全球比特币开采中占主导地位

这份剑桥替代金融替代金融中心的报告证实，美国和加拿大占据了全球比特币挖掘，共同控制着报告的活动的80％以上。

The latest report from the Cambridge Centre for Alternative Finance (CCAF) has revealed that the United States and Canada are home to the majority of bitcoin mining activity, with the two countries together controlling over 80% of the reported activity.

剑桥替代金融中心（CCAF）的最新报告显示，美国和加拿大是大多数比特币采矿活动的家园，两国共同控制着报告的活动的80％以上。

According to the latest CCAP survey findings, the U.S. is the largest global mining hub, handling 75.4% of reported activity.

根据最新的CCAP调查结果，美国是最大的全球矿业中心，处理报告的活动的75.4％。

Canada followed in a distant second place with 7.1% of the activity, which may indicate that mining companies are largely concentrated in North America.

加拿大紧随其后的是第二名，其中7.1％的活动可能表明矿业公司主要集中在北美。

The survey findings also revealed that 98% of respondents’ power capacity is dedicated to bitcoin mining.

调查结果还显示，98％的受访者的电力能力专用于比特币采矿。

However, the report’s summary does acknowledge possible bias in the findings, and it’s worth noting that the figures may not fully represent the overall activity.

但是，该报告的摘要确实承认调查结果可能偏见，值得注意的是，这些数字可能无法完全代表整体活动。

Despite this, the survey findings “reveals directionally relevant developments,” including emerging activity in South America and the Middle East. Until mid-2021, China was widely recognized as the No. 1 bitcoin mining country. However, a crackdown against this activity forced some mining companies to relocate to neighboring countries and, in some cases, to the U.S.

尽管如此，调查结果“揭示了方向相关的发展”，包括南美和中东的新兴活动。直到2021年中，中国被广泛认为是第一比特币矿业国家。但是，对这项活动的镇压迫使一些矿业公司搬到邻国，在某些情况下是美国

As reported by Bitcoin.com News in 2022, while the crackdown did impact miners’ operations, it did not result in China immediately losing its position as one of the top bitcoin mining countries. The report suggested that miners had resorted to using virtual private networks (VPN) to conceal their location from authorities.

正如Bitcoin.com News在2022年报道的那样，尽管镇压确实影响了矿工的业务，但这并没有导致中国立即失去其作为最顶尖的比特币矿业国家之一的地位。该报告建议，矿工已诉诸使用虚拟专用网络（VPN）将其位置隐藏在当局中。

When China started cracking down against bitcoin miners, some reports indicated that this was being done in part to help the country achieve President Xi Jinping’s goal of carbon neutrality within four decades. The crackdown, along with pressure from climate activists, forced bitcoin mining to prioritize clean and renewable energy sources.

当中国开始与比特币矿工打击时，一些报告表明，这是为了帮助该国实现XI Jinping在四十年内实现碳中立性的目标。镇压以及气候活动家的压力迫使比特币开采优先考虑清洁和可再生能源。

Now, more than three years later, the latest CCAF survey findings indicate that miners’ electricity mix is predominantly sustainable (52.4%)

现在，三年多以后，最新的CCAF调查结果表明，矿工的电力组合主要是可持续的（52.4％）

“The survey indicates that miners’ electricity mix is predominantly sustainable (52.4%), with renewables accounting for 42.6%. Hydropower constitutes the largest sustainable source (23.4%), followed by wind (15.4%), nuclear (9.8%), solar (3.2%), and other renewables (0.5%). Fossil fuels make up 47.6%, primarily natural gas (38.2%), which is also the single largest energy source, followed by coal (8.9%) and oil (0.5%),” the CCAF report stated.

“调查表明，矿工的电力混合物主要是可持续的（52.4％），可再生能源占42.6％。水电构成最大的可持续来源（23.4％）（15.4％），随后是核（9.8％），太阳能（3.2％）和其他可再生能源（0.5％）。 （38.2％），也是最大的能源，其次是煤炭（8.9％）和石油（0.5％），” CCAF报告说。

The survey data also revealed that the annualized electricity consumption associated with bitcoin mining in 2023 is estimated at 138 terawatt-hours, which represents a 17% increase year over year and about 0.54% of global electricity consumption.

调查数据还显示，估计与2023年比特币开采相关的年度用电量估计为138个Terawatt小时，占份同比增长17％，约占全球电力消耗的0.54％。

CCAF noted that bitcoin miners in the survey reported a median electricity cost of $45 per megawatt-hour and “an all-in cost of $55.50 per megawatt-hour, with electricity constituting more than 80% of their cash-based operational expenses.”

CCAF指出，调查中的比特币矿工报告说，中位电力成本为每兆瓦时45美元，“每兆瓦小时的全部成本为55.50美元，电力占其基于现金的运营费用的80％以上。”

Meanwhile, the CCAF survey data revealed that 98% of respondents’ power capacity is dedicated to bitcoin mining. Still, the survey report acknowledges that the bitcoin mining industry is at a “critical juncture,” and unless it starts to diversify, it is headed for even dire times.

同时，CCAF调查数据显示，有98％的受访者的电力能力专用于比特币采矿。尽管如此，调查报告仍然承认，比特币矿业行业处于“关键关头”，除非它开始多样化，否则它持续了艰难的时期。

“Diversification into high-growth sectors like HPC serving computationally intense AI workloads, leveraging existing infrastructure, is emerging as a key adaptive strategy,” the report explains.

该报告解释说：“利用现有基础架构的HPC等高增长领域的多元化正在为计算强度的AI工作负载，这是一种关键的适应性策略。”

The CCAF identifies innovative energy solutions like using flared natural gas, recovering waste heat, and demand-side response as some of the ways miners can deal with dwindling mining revenues. Hashprice hedging could also help manage financial risks in the future, similar to how energy price hedging is already a key risk mitigation strategy, the report added.

CCAF确定了创新的能源解决方案，例如使用喇叭形天然气，恢复废热以及需求侧的反应，因为矿工可以应对逐渐减少的采矿收入。报告补充说，HashPrice套期保值还可以帮助将来管理财务风险，类似于能源价格对冲已经成为关键风险降低策略。
