Right now the answer is no: this is Bitcoin season territory. Most of the market is losing ground against BTC.

The basics

What altseason means

Altseason, or altcoin season, is the stretch of the crypto cycle in which most altcoins outperform Bitcoin. It is when portfolios full of smaller coins suddenly look brilliant, and it has historically arrived late in bull markets, after Bitcoin has already made its move.

The classic convention declares altcoin season when at least 75 percent of the top coins beat Bitcoin over the measurement window, and Bitcoin season when 25 percent or fewer manage it. Between those lines, nobody owns the market.

Our definition, declared

How this gauge is measured

BitPulse measures the share of the top 50 coins by market capitalization, excluding Bitcoin, whose price beats Bitcoin over the last 30 days. It updates once a day, the series is archived from the first reading, and past values are never rewritten.

Other sites use a 90 day window over the top 50. Both are legitimate; ours favours a fresher reading. What matters is that the definition is declared and stable, so the number means the same thing every single day.

Interpretation

How to read the number

25 percent or less: Bitcoin season

The market is concentrating in Bitcoin. Altcoins bleed against BTC even when their dollar prices rise. Typical of early and mid cycle.

Between 25 and 75: no man's land

Rotation without conviction. Some sectors run, most lag. This is where the market spends most of its time, and where narratives are loudest and least reliable.

75 percent or more: altcoin season

Broad outperformance against Bitcoin. Historically rare and short, clustered late in bull cycles, usually after Bitcoin dominance has turned down.

Context

Altseason and the Bitcoin cycle

Altseason is not an independent event: it is a late chapter of the Bitcoin cycle. Money enters through Bitcoin, confidence builds, and only then does it spill outward. That is why this gauge is best read together with Bitcoin dominance.

BitPulse tracks the cycle with a projection engine whose ranges are published before the fact and checked in public, hit or miss. See how it works or open the live app.
