Why was Bitcoin up on Sep 3, 2026, 5:22 PM UTC?

Bitcoin is up 5.3% over 24h with minimal short-term movement (0.15% in 15min), suggesting the recent gains have already settled. The news is mostly structural (new platforms, banking partnerships, memecoin activity) rather than price-catalytic—none directly explains the 24h move. The yen strength mentioned could be a contributing factor to recent upside, but the lack of volatility in the last hour suggests this rally has already priced in available information.
