Bitcoin network hashrate has declined significantly over recent weeks, resulting in a mining difficulty adjustment of 7.7% to 133.79T. The seven-day average hashrate dropped from approximately 1086 EH/s at the end of February to approximately 937 EH/s. Analysts point to multiple factors driving this trend, including major miners shifting to higher-yield AI workloads, inefficient miners going offline due to weak hashrate prices, and potential disruptions from geopolitical conflicts in regions like the Middle East and volatility in energy markets.
