Altseason index touching the yearly high Which top 100 alt to hold until 2027?

Altseason is getting close.
But 64 is not 75.

The top-100 Altcoin Season Index reached 64 around its 2026 high, meaning roughly two-thirds of eligible alts beat $BTC over the previous 90 days.

That is real rotation.

It is not full altseason yet.

Coinlib currently shows 64, while BlockchainCenter’s Top-50 version sits lower at 59. Bitcoin dominance is still around 59%.

So capital is spreading out. It just isn’t abandoning BTC.

That distinction matters if the question is what to hold into 2027.

I wouldn’t chase the coins sitting at the top of a 90-day leaderboard.

Momentum gets you noticed.

Usage, revenue and infrastructure give you a reason to survive the next drawdown.

My 2027 watchlist would be:

$LINK — my strongest infrastructure pick. It is already up about 83% over 90 days, but the bigger thesis is CCIP 2.0 and Chainlink’s position between institutions, tokenized assets and multiple chains.

$AAVE — boring in the best way. Lending has survived multiple cycles, and AAVE is up roughly 104% over the same 90-day window.

$SOL — the higher-beta ecosystem bet. Real users, deep liquidity and one of the strongest non-EVM app ecosystems.

$ETH — less explosive, but still the base settlement layer behind a huge part of DeFi and tokenized finance.

$HYPE — the aggressive pick. Strong trading activity and fee generation make it interesting, but token unlocks and valuation matter much more on a 2027 horizon.

The biggest mistake now would be thinking:

“Altseason Index is high, so buy alts.”

No.

A high index tells you breadth is improving.

It does not tell you which tokens will survive when the index falls back to 30.

For a 2027 hold, I’d follow revenue, real usage, token supply and infrastructure demand.

Not whichever ticker pumped hardest this week.

If I had to choose one today, LINK would be the one.

What’s yours?
