美國和加拿大在全球比特幣開採中占主導地位

這份劍橋替代金融替代金融中心的報告證實，美國和加拿大佔據了全球比特幣挖掘，共同控制著報告的活動的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.

劍橋替代金融中心（CCAF）的最新報告顯示，美國和加拿大是大多數比特幣採礦活動的家園，兩國共同控制著報告的活動的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.

根據最新的CCAP調查結果，美國是最大的全球礦業中心，處理報告的活動的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.

加拿大緊隨其後的是第二名，其中7.1％的活動可能表明礦業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.

調查結果還顯示，98％的受訪者的電力能力專用於比特幣採礦。

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，該報告的摘要確實承認調查結果可能偏見，值得注意的是，這些數字可能無法完全代表整體活動。

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.

儘管如此，調查結果“揭示了方向相關的發展”，包括南美和中東的新興活動。直到2021年中，中國被廣泛認為是第一比特幣礦業國家。但是，對這項活動的鎮壓迫使一些礦業公司搬到鄰國，在某些情況下是美國

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年報導的那樣，儘管鎮壓確實影響了礦工的業務，但這並沒有導致中國立即失去其作為最頂尖的比特幣礦業國家之一的地位。該報告建議，礦工已訴諸使用虛擬專用網絡（VPN）將其位置隱藏在當局中。

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.

當中國開始與比特幣礦工打擊時，一些報告表明，這是為了幫助該國實現XI Jinping在四十年內實現碳中立性的目標。鎮壓以及氣候活動家的壓力迫使比特幣開採優先考慮清潔和可再生能源。

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

現在，三年多以後，最新的CCAF調查結果表明，礦工的電力組合主要是可持續的（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.

“調查表明，礦工的電力混合物主要是可持續的（52.4％），可再生能源佔42.6％。水電構成最大的可持續來源（23.4％）（15.4％），隨後是核（9.8％），太陽能（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報告說。

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.

調查數據還顯示，估計與2023年比特幣開採相關的年度用電量估計為138個Terawatt小時，佔份同比增長17％，約佔全球電力消耗的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，調查中的比特幣礦工報告說，中位電力成本為每兆瓦時45美元，“每兆瓦小時的全部成本為55.50美元，電力佔其基於現金的運營費用的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.

同時，CCAF調查數據顯示，有98％的受訪者的電力能力專用於比特幣採礦。儘管如此，調查報告仍然承認，比特幣礦業行業處於“關鍵關頭”，除非它開始多樣化，否則它持續了艱難的時期。

“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.

該報告解釋說：“利用現有基礎架構的HPC等高增長領域的多元化正在為計算強度的AI工作負載，這是一種關鍵的適應性策略。”

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確定了創新的能源解決方案，例如使用喇叭形天然氣，恢復廢熱以及需求側的反應，因為礦工可以應對逐漸減少的採礦收入。報告補充說，HashPrice套期保值還可以幫助將來管理財務風險，類似於能源價格對沖已經成為關鍵風險降低策略。
