Frequently Asked Questions
Altcoin Season FAQ
Answers to common questions about altcoin season, Bitcoin dominance, market breadth, and how to interpret the tracker.
What score means altcoin season?
A score of 75 or higher puts the index in its altcoin season zone: at least 75% of the eligible leading altcoins outperformed Bitcoin during the selected period. This site treats the season as confirmed only when Bitcoin dominance is also 42% or less on the same day.
Is falling Bitcoin dominance enough to confirm altcoin season?
No. Dominance can fall because stablecoins or one large coin gained share, without most altcoins beating Bitcoin. This site confirms an altcoin season only when two things are true on the same day: the Altcoin Season Index is 75 or more, and Bitcoin dominance is 42% or less.
Why are stablecoins excluded?
Stablecoins are designed to hold a fixed value, so they almost never beat or trail Bitcoin by their own merit. Counting them would add coins that cannot take part in a rotation and pull the index towards the middle. Wrapped assets, liquid-staking receipts and commodity-backed tokens are excluded for the same reason.
How often is the tracker updated?
Current market data from CoinGecko refreshes approximately every four hours. One snapshot per day is kept as the durable record, and every dated figure on the site is the value in that day's snapshot. Days before recording began are not reconstructed.
Does a high score mean every altcoin will rise?
No. The score describes broad relative performance. Individual assets can still fall, underperform, or carry substantial risk.
Why does this index differ from the one on other sites?
Providers measure different things under the same name. This index counts the 50 largest eligible altcoins over 90 days and keeps each day as it was recorded. Others use the top 100, different exclusions or a shorter window, so the same day can produce different readings. Compare the universe and the window before comparing the numbers.
