Altcoin spot volume just hit 4x $BTC — highest since September 2025.

72.5% of top alts crushed $BTC last week.

The kicker? This isn't leverage-driven. Altcoin perp OI barely moved in 30 days.

Last time spot volume ratio was this high: September 2025.

$BTC ripped to ~$126K the next month.

Spot rotation is real. Alts are eating.
