Crypto Market Shifts from Bitcoin Season to Altcoin Season
The crypto market has recorded a significant signal shift as Glassnode's Altcoin Cycle Signal moved from Bitcoin season to altcoin season for the first time since January 2026.
The signal compares BTC's performance against a market-cap-weighted basket of the top 250 cryptocurrencies, excluding stablecoins. A high reading indicates that altcoins are outperforming BTC, while low readings signal leadership remains with the first cryptocurrency.
The rally began concentrated in Bitcoin but has now spread to the rest of the market, according to Glassnode's data. The first leg of the August rally saw alternative cryptocurrencies relatively flat while BTC advanced, but today's rally has ignited full market breadth.
