Altcoin Season Index Hits 49 as Bitcoin Dominance Holds Near 58% and 55% Remains Key

On June 2, 2026, bitcoin slipped below $68,000, with its market dominance hovering around 58% and the Altcoin Season Index rising to 49. The reading remains 26 points under the 75 level typically used to confirm an altcoin season, leaving the market in a tentative, selective-rotation phase. Analysts say a sustained drop in BTC.D below 55% to 56%, alongside stronger breadth in large caps, would be needed to validate a broader shift into altcoins.
