Altcoin Season
Period when altcoins outperform Bitcoin. Typically the late stage of a bull run.
Altseason: when altcoins outperform BTC. Index ≥75 means altcoin season. Bull cycle sequence: BTC → ETH → large alts → memecoins. Memecoin mania = top is near.
In plain words
Crypto outside Bitcoin (ETH, SOL, XRP, memes) outperforms BTC in % terms. Mid-to-late bull phase: capital flows into BTC first, then rotates into alts. When memecoins start doing 100x in a week, the cycle top is near.
Example
March 2024: BTC ATH at 73k. 2 months later ETH +60%, SOL +80%, Nov memes +500%. Altseason index 78. Nov-Dec 2024 = textbook altseason.
