Why was Bitcoin down on Jul 17, 2026, 7:28 PM UTC?

Bitcoin's modest negative movement (-0.36% in 24h) doesn't appear to be driven by the news provided. The recent headlines mix geopolitical concerns (Iran strikes), regulatory developments (Senator Warren's crypto reporting request), and AI-related sentiment shifts, but none clearly explains the minor downside. The price action suggests routine technical volatility rather than a reaction to any single catalyst.
