Why was Bitcoin down on Jul 31, 2026, 8:07 PM UTC?

Bitcoin's 2.95% 24-hour decline likely reflects broader macro headwinds from rising US Treasury yields mentioned in today's news, which typically pressures risk assets like crypto. The recent regulatory moves (Circle's charter, ETF discussions) and self-custody concerns appear insufficient to explain this specific downside—this looks primarily driven by macroeconomic factors rather than crypto-specific news.
