## Key facts

1 publisher(s) tracked. Independent verification remains incomplete. Routine single-source report; no generated explanation. Read the linked source.
Evidence strength: Single source, 1 publisher group(s) (The Block); this describes source coverage, not truth or causation.
After site detection, observed returns were 5 minutes: -0.06% (difference from BTC -0.22 pp; 20/10/2026, 17:15 → 20/10/2026, 17:21, UTC+8; OKX · USDT); 1 hour: -0.65% (difference from BTC -0.88 pp; 20/10/2026, 17:15 → 20/10/2026, 18:17, UTC+8; OKX · USDT). Unlisted windows are unavailable.
In the preceding 30 days, the 99th percentile of absolute hourly returns was 8.79% (OKX · USDT; cutoff 20/10/2026, 17:15, UTC+8). This hourly baseline is not directly comparable with a minute move.
