The (ASI) Altcoin Season Index is a simple online tool that tells you whether it’s currently Altcoin season or Bitcoin season in the crypto market.
It measures how many of the top Altcoins are doing better than Bitcoin over the last 90 days. If most Altcoins are outperforming Bitcoin, it is alt season. If Bitcoin is beating most Altcoins, it’s a Bitcoin season.
The Altcoin season index is scored on a scale from 1 to 100.

The Index counts the top 100 cryptocurrencies by market cap. (excluding stablecoins like USDT and asset-backed tokens like WBTC)
It looks at how each of those coins has performed compared to Bitcoin over the last 90 days.
If over 75% of those top 100 coins did better than Bitcoin in that particular period, it’s considered Altcoin season.
If 25% or fewer of the top 100 cryptocurrencies outperform Bitcoin, it is considered Bitcoin Season.
For example, a score of 85 means that 85% of the top 100 cryptocurrencies have outperformed Bitcoin over the past 90 days.
DigitalCoinPrice shows the Index for yesterday, last week, last month, as well as the yearly high and low. Key rule you must know, 75% of the top 100 coins must outperform Bitcoin over 90 days to confirm an Altcoin season.

The Altseason Index teaches you a few important things:
Market rotation is real, as capital moves between Bitcoin and Altcoins in patterns. The index shows when the rotation is happening, so you can decide accordingly.
It shows that not all Altcoin rallies are same. If a score is 80, that means the rally is broad, and most top coins are rising, but a few smaller coins stay still flat.
Timing matters. Entering an Altcoin position when the index is at 20 (deep Bitcoin season) vs. 70 (approaching Altcoin season) can mean the difference between catching a rally early or buying near the top.
It is a confirmation tool, not a predictor. The Altcoin season index chart is best used to confirm trends already in motion in combination with other tools for accurate decision making.
Alt seasons don’t last forever; the seasons typically last a few weeks to a few months. So it’s important to manage risk and take profits in stages.
When the Altcoin Season Index reads 75 or above, that means over 75% of top Altcoins have outperformed Bitcoin over the last 90 days, so it’s an Altcoin Season.
When the Altcoin season index score is 25 or below, that means Bitcoin is taking the front seat and outperforming most Altcoins in the market.
A score of 75 or above indicates Altseason. Below 25 means Bitcoin season, and anything in between is a mixed market.
The Altseason index changes on a daily basis, so the season is always shifting. Check the live Altcoin Season Index chart updated score on DigitalCoinPrice. If the index reads 75 or above, it’s an Altcoin Season.

Alt Season most commonly follows a Bitcoin bull run. When Bitcoin reaches a price at its peak, profit usually tends to rotate into Altcoins. Historically, it has been observed in the mid-to-late stages of crypto bull markets. Typically, traders watch BTC dominance, the Altcoin season index, and ETH/BTC trends to spot the early signs.
Basically, Altcoin Season Index is a lagging indicator; it is better to consider this as a confirmatory tool than a predictor. Since it is based on 90-day performance, it tends to reflect rallies already underway. For early signals, you can use it with other indicators such as BTC dominance and ETH/BTC for better timing.
