Altcoin Spot Volume Nears Four Times Bitcoin’s as ETF Inflows Shrink

Altcoin spot volume has surged to nearly four times that of Bitcoin's, according to Glassnode. This is the highest ratio since September 2025.

Wintermute notes that retail clients on its OTC desk sold BTC last week to fund the rotation into altcoins.

The US spot Bitcoin ETFs took in nearly $2.4 billion over the same five sessions, but each day's inflow came in below the previous day's, dropping from $999 million on September 21 to $134.5 million on September 25.
