The −8% volume dip is contained — not a red flag
24h derivatives volume is $4.2B (−8% WoW), but the drop is concentrated on BTC-PERP & ETH-PERP during the Asia session and lines up with Hyperliquid's 0-fee promo on those exact pairs (Jun 16). Open interest held at $2.8B, p99 matching latency is 3.1ms, liquidations $46M — all normal. Traders aren't leaving; they're trading the same book cheaper elsewhere for a week.
