90-Day Altcoin Season Index Sits at 51, Below Its 75-Point Threshold

A 90-day altcoin-season gauge stood at 51 on Oct. 23, below the 75-point level for altcoin season, as its top-50 basket measured performance against Bitcoin (BTC). The gauge reaches altcoin-season territory when at least 75% of the 50 tracked coins outperform BTC during the 90-day period. The 51 reading is below that threshold. A separate measure tracks eligible assets among the top 100 and excludes stablecoins, wrapped tokens and asset-backed tokens. It also uses a 90-day comparison, defining altcoin season as 75% or more outperforming Bitcoin and Bitcoin season as 25% or less.
