Why was Bitcoin up on Jul 21, 2026, 3:55 AM UTC?

Bitcoin's modest upward movement (0.98% in 24h) appears largely detached from the news cycle—Saylor's cash raise, regulatory developments in Brazil and Russia, and tokenization proposals are structural stories, not immediate price catalysts. The small intraday gains (0.06-0.3%) suggest technical consolidation rather than news-driven momentum, though the "volmageddon" warning hints at elevated volatility that could trigger sharp moves in either direction.
