When is it altcoin season?
Bitcoin had a good quarter. Did your altcoins?
Most of the time, the honest answer is no. Altcoin season is the rarer stretch when the majority of large coins outrun Bitcoin, and KryptoKap's season meter counts exactly how many are doing it right now.
How the meter counts
The meter counts how many of the top 100 coins beat Bitcoin over 90 days. At 68 the market is mixed; it takes 75 to call altcoin season. Free to reuse
KryptoKap's season meter checks the top 100 coins, leaving out stablecoins and gold tokens, and counts how many beat Bitcoin's price change over the last 90 days.
A reading of 75 or more means altcoin season. A reading of 25 or less means Bitcoin season. In between, the market is mixed.
Altcoin seasons have tended to come late in rallies, when gains in Bitcoin spill over into riskier coins, but past patterns don't promise future ones.
Beating Bitcoin, even in a falling market
Take the top 100 coins by market cap, leave out stablecoins and gold tokens, and compare each one's 90-day price change with Bitcoin's. If 80 of them did better, the meter reads 80, which is altcoin season.
A coin that fell 10% while Bitcoin fell 20% counts as beating Bitcoin. The meter is about relative performance, not whether prices went up.
Reading it with other signals
Altcoin seasons usually come with falling Bitcoin dominance and rising trading volume in smaller coins. When the meter is high but dominance is flat, gains may be concentrated in a few large altcoins.
Like any backward-looking measure, it can change quickly once a trend ends.
A ten-coin version of the count
Seven of ten coins beat Bitcoin's 12%, so the meter reads 70. That's mixed, just short of the 75 needed for altcoin season. Coins H and I gained but still count as losers. Free to reuse
Shrink the meter to ten coins to see how it behaves. Over 90 days Bitcoin rose 12%. Coin A rose 40%, B 30%, C 25%, D 22%, E 18%, F 15% and G 13%. Those seven beat Bitcoin. H rose 10%, I rose 5% and J fell 8%. Those three didn't.
Seven out of ten is 70%, so a meter built this way reads 70. That's a mixed market, not altcoin season, even though most coins did better than Bitcoin and nine out of ten went up. On the real meter, with 100 coins, the threshold is 75 coins or more. It's a high bar on purpose, which is why true altcoin seasons are fairly rare.
Notice how close G is to the line. It beat Bitcoin by a single percentage point, and a small shift in either price could flip it. With 100 coins, a cluster of coins sitting near Bitcoin's return can push the meter several points in a day. If the reading changes quickly, look at how many coins sit just above or below Bitcoin's 90-day change before reading much into it. The same applies near the 25 line for Bitcoin season.
When a few big coins skew the picture
Two big altcoins doubling can drag dominance from 60.0% to 55.3% while the season meter sits at 30. The meter counts coins; dominance weighs dollars. Free to reuse
The season meter counts coins and gives each one an equal vote. Bitcoin dominance weighs dollars, so large altcoins count for much more than small ones. The two can tell different stories over the same 90 days.
In the example, Bitcoin rises 10%, from $1.80 trillion to $1.98 trillion. Two large altcoins worth $0.40 trillion together double to $0.80 trillion, while the rest of the market stays flat at $0.80 trillion. Dominance falls from 60.0% to 55.3%, which looks like money leaving Bitcoin. But only 30 of the top 100 beat Bitcoin, so the meter reads 30, which is mixed and leans toward Bitcoin. The gains are concentrated, not spread out.
Broad altcoin seasons, like the one in early 2018 and the one in the first half of 2021, showed both signals together, with falling dominance and most coins beating Bitcoin. When only one of the two moves, the honest reading is that a few coins are doing well. To see which ones, sort KryptoKap's coin table by 90-day change and compare the leaders with Bitcoin's row.
Key terms
Season meter
Share of the top 100 coins beating Bitcoin over 90 days.
Altcoin season
Meter at 75 or above.
Bitcoin season
Meter at 25 or below.
Outperform
Rise more, or fall less, than a benchmark.
Winning by a little counts the same as winning big
How much they won by. A coin that beat Bitcoin by 0.1% counts the same as one that beat it by 300%.
Whether prices went up. Coins that fell less than Bitcoin count as winners.
What comes next. It looks back 90 days and can turn quickly when a trend ends.
What people get wrong
Altcoin season doesn't mean every altcoin rises. It means most of the top 100 beat Bitcoin.
The meter describes the last 90 days. It doesn't predict the next 90.
Why it matters
It shows whether gains are spreading across the market or concentrated in Bitcoin.
Common questions
Why 90 days?
Long enough to smooth out daily noise, short enough to reflect the current market.
Is it altcoin season right now?
Check the season meter on the KryptoKap home page. It updates with prices and shows how many of the top 100 beat Bitcoin over 90 days.
How long does altcoin season usually last?
There's no set length. Past stretches with most large coins beating Bitcoin have lasted from a few weeks to a few months, and some readings above 75 last only days. Because the meter uses 90-day returns, it can stay high for a while after the strongest gains have already happened.
Do stablecoins count in the season meter?
No. Stablecoins and gold tokens are left out because they're designed to hold a steady price, so they would almost never beat Bitcoin in a rally or almost always beat it in a fall. Including them would distort the count.
Can it be altcoin season while prices fall?
Yes. The meter compares each coin with Bitcoin, not with zero. If Bitcoin falls 25% over 90 days and most large coins fall only 10%, most of them beat Bitcoin and the meter can read above 75 during a falling market.
