Why was Bitcoin up on Jul 21, 2026, 7:25 PM UTC?

Bitcoin's modest gains (1.87% over 24h) appear driven more by regulatory tailwinds than immediate price catalysts—the White House crypto clarity deal and Russia's new framework suggest improving institutional acceptance. However, the short-term flatness (0.02% in 15min, 0.11% in 1h) suggests this positive news is being absorbed gradually rather than triggering sharp buying, and quantum computing concerns plus the Tether merger uncertainty may be offsetting sentiment.
