Altcoin Season Signal Flips as Crypto Market Expands Beyond Bitcoin

A key indicator from Glassnode has flipped to signal that altcoin season is underway as the broader crypto market rallies. The signal change follows a breakout by Bitcoin above $85,000, which also triggered nearly $1 billion in inflows into U.S. spot ETFs and heavy short liquidations.

The shift to altcoin season was marked by gains across a larger share of the market, with Ethereum rising 6%, Solana increasing 4.5%, and Dogecoin posting a double-digit advance over the past 24 hours.

Glassnode's indicator compares Bitcoin's performance to that of a broad basket of crypto assets to identify periods when participation shifts away from BTC-dominated returns.
