Why was Bitcoin down on Jul 31, 2026, 10:19 AM UTC?

Bitcoin is essentially flat with minimal intraday movement (0.03% in 15min, -0.12% in 1h), suggesting a lack of directional conviction. The -1.31% 24h decline appears disconnected from today's news—the reported items (AI data center funding, wallet security flaw, Japan's rate decision) don't directly explain the recent pullback, so this is likely technical consolidation or broader macro positioning rather than driven by breaking news.
