Why was Bitcoin down on Aug 1, 2026, 12:13 AM UTC?

Bitcoin is down 2.83% over 24 hours but essentially flat in the short term (±0.12% in 15min), suggesting consolidation rather than directional conviction. The news items—regulatory progress (Circle's charter), security concerns (Coldcard exploit), and structural analysis (perps, bull run barriers)—don't clearly explain today's minor decline; this appears to be routine intraday volatility rather than a response to specific catalysts.
