North America's electricity supply has become increasingly tight. In the allocation of electricity priority, data centers are often favored—by comparison, the attractiveness of BTC mining is far less than that of the former. There are several core reasons behind this: First, the cost of mining in North America is significantly higher than in the Middle East, Central Asia, and other regions, severely compressing profit margins. Second, investing the same electricity resources into data centers yields a higher return, and has a more direct impact on boosting the stock prices of listed companies. Third, the mining industry is gradually evolving into a sunset industry in the traditional sense, with its attractiveness continuously declining. These factors combined have led to a continuous shrinkage of North America's share in global BTC mining, with the hash rate concentration steadily decreasing.
