Why was Bitcoin up on Jul 18, 2026, 1:46 AM UTC?

Bitcoin is essentially flat over the past day (+0.27%), with minimal 15-min and 1h volatility, suggesting no strong directional catalyst right now. The recent news is mixed—geopolitical tensions (Iran strikes, US stock pressure) and regulatory scrutiny (Senator Warren) could be weighing on sentiment, but the modest moves don't clearly reflect any of these headlines, indicating this is likely just normal intraday consolidation rather than a news-driven event.
