Frequently asked questions
What is the Altcoin Season Index?
The Altcoin Season Index tracks 8 major altcoins against BTC over a trailing 90-day window. When 6 or more of the 8 tracked altcoins have outperformed BTC over that period, the index reads "Altcoin Season" — a phase that historically accompanies broad market risk expansion and increased altcoin momentum.
What do the four regime labels mean?
"Altcoin Season" means 6 or more of 8 tracked altcoins outperformed BTC over 90 days. "Altcoin Leaning" means more than half outperformed. "Bitcoin Leaning" means most alts underperformed BTC. "Bitcoin Dominance" means fewer than 25% of tracked altcoins outperformed BTC — a strong Bitcoin-dominant phase with broad relative alt weakness.
Why does the index use a 90-day window?
The index uses 90-day relative performance as its primary signal because it smooths short-term noise while still capturing meaningful medium-term regime shifts. Altcoin seasons have historically lasted 2–6 months and followed periods of Bitcoin accumulation and consolidation.
Is the Altcoin Season Index financial advice?
No. The index presents historical performance data and a systematic regime label — it is market information, not financial advice, and past performance does not predict future returns.
