美国替代中国成为全球最大的比特币挖矿中心！政府大力协助矿工自建电厂？

Core Insights - The global Bitcoin mining landscape is undergoing a significant transformation, with the United States replacing China as the leading Bitcoin mining center, supported by government initiatives to solidify this position [1][4][5]. Group 1: U.S. Dominance in Bitcoin Mining - According to a recent study by the Cambridge Centre for Alternative Finance, the U.S. controls 75.4% of the global Bitcoin hashing power, contributing approximately 600 EH/s to the total global hashing power of around 796 EH/s [4][5]. - The shift in dominance is largely attributed to China's ban on Bitcoin mining in June 2021, which led to a mass migration of mining operations to the U.S., particularly to states with abundant cheap energy [5][6]. Group 2: U.S. Government Support - The current U.S. administration, under President Trump and Commerce Secretary Howard Lutnick, has adopted a pro-Bitcoin stance, viewing it as a strategic opportunity for economic and technological leadership [8][9]. - The U.S. government plans to establish a "Bitcoin Strategic Reserve," officially holding Bitcoin as a national asset, although details on the reserve's scale and management are yet to be disclosed [9]. Group 3: Investment Accelerator Initiative - The U.S. Commerce Department is launching an "Investment Accelerator" program to facilitate large-scale investments (over $1 billion) in the mining sector, providing streamlined administrative support to overcome investment barriers [9][10]. - This initiative aims to enable miners to build their own power plants near data centers, allowing them to control energy costs and reduce reliance on the public grid, thereby enhancing the competitiveness and stability of the U.S. mining industry [10]. Group 4: Centralization Concerns - The concentration of Bitcoin mining power in the U.S. raises concerns about potential risks similar to those experienced when China dominated the market, including fears of a "51% attack" or government intervention [11][13]. - The Bitcoin community faces a critical juncture, needing to balance the benefits of U.S. policy support with the necessity of promoting decentralization to mitigate potential future risks [14].
