币界网报道：Bitcoin's hashrate experienced its steepest decline in years, dropping nearly 10% within a week despite BTC's price surge above $70,000. The network's computing power fell from over 700 exahashes per second (EH/s) to around 600 EH/s, marking the fastest drop since China's mining ban in 2021. Analysts suggest the sudden decline may stem from reduced mining profitability due to the recent Bitcoin halving, which cut block rewards by 50% to 3.125 BTC. While some miners are shutting down less efficient equipment, others are relocating operations to regions with cheaper electricity. The hashrate drop coincides with Bitcoin's price recovery from its post-halving lows, highlighting the complex relationship between mining economics and market dynamics. Industry observers note such volatility isn't uncommon after halving events, as the network typically stabilizes within months as miners adjust operations.
