Why was Bitcoin up on Jul 21, 2026, 8:07 AM UTC?

Bitcoin's modest 3.09% gain over 24 hours appears supported by positive institutional flows—Bitcoin ETFs are on their longest inflow streak since May, which typically signals renewed institutional interest. The recent parliamentary inquiry and Grayscale's Worldcoin ETF filing suggest growing regulatory clarity and product expansion, though these are unlikely the primary driver of today's specific price movement. Current 15min and 1h changes are minimal, indicating the move is gradual rather than driven by breaking news.
