It always starts the same way.
What defines Altcoin Season?
it’s officially Altcoin Season when 75% of the top 100 coins (excluding stablecoins and wrapped tokens) outperform Bitcoin over the last 90 days. This threshold reflects a broad market rotation away from Bitcoin dominance toward diversified altcoin growth.
But let’s break it down how to spot that we are in the Altseason phase.👇
📉 Bitcoin Dominance Starts Slipping
What it is: Bitcoin Dominance is the percentage of the total crypto market cap that belongs to BTC
Key signal: When BTC dominance drops, it’s usually a sign that traders are rotating into riskier bets like altcoins.
🧠 Traslation: money is flowing from BTC to altcoins
📈 ETH/BTC Ratio Begins to Climb
What it is: the ETH/BTC ratio tracks Ethereum’s strength compared to Bitcoin. It signals that the market is ready to play with more leverage.
Usually ETH leads. Then the rest alts follow.
It’s like Ethereum’s is the cool kid, and everyone else just wants to join the party.
If Ethereum is outperforming BTC → other altcoins may follow.
🚀 Mid & Low Caps Start Pumping
Not just ETH or BNB, but you’ll know it’s really happening when mid-caps like LINK, AVAX, or SEI and even low-cap gems start doing +30% days out of nowhere
That’s not just market noise, that’s narrative-driven FOMO.
🔊 Altcoin Volume Goes Crazy
If people start trading a LOT more of smaller coins (check the trading volume), that means more buyers, more hype… and bigger price swings.
Volume = interest.
Interest = movement
More volume = more liquidity = faster moves = higher risk/reward.
🧃 Meme Coins Come Back From the Dead
You’ll hear it in the memes first.
When DOGE, PEPE, WIF, and friends start trending again, it’s a sign retail is back.
And when retail’s back? Volatility spikes — and so do opportunities (if you don’t get rugged).
