Altcoin spot trading volume has climbed to nearly 4X Bitcoin's, reaching its highest ratio since September 2025. Glassnode also reports that 72.5% of tracked altcoins have outperformed BTC, up sharply from 39% during August.

That looks like capital rotation, but it does not automatically confirm altseason. The current Altcoin Season Index is 53, still below the 75 threshold used to define a broad altseason.

There is another side to this. Glassnode says similar bursts of aggressive altcoin risk taking have often appeared around local Bitcoin tops. BTC is also trading below its recent ~$87K high, while ETF inflows have slowed across recent sessions.

So the real question is whether altcoin volume is expanding the crypto rally or simply rotating profits ahead of another $BTC move.

For now, volume confirms rising risk appetite. The next signal is whether Bitcoin holds its range while altcoins continue gaining breadth.
