The alt season isn’t arriving because there isn’t enough profit to move
How rotation actually works
So the question that matters is whether bitcoin has produced enough profit to create the liquidity a rotation needs. Whether bitcoin is high is a separate question, with a separate answer. That’s why the wait for the alt season has dragged on for months while bitcoin’s price does whatever it likes.
The most direct way to look at it is to count how many coins are beating bitcoin. In our archive, on the day I write, it’s 36 out of 308 over the previous ninety days, or 12 percent. In a real rotation that number sits well above half.
As of 7 December 2025, over the previous ninety days, 36 coins out of 308 had a return higher than Bitcoin’s: 12 percent of the market measured.
The comparison with the cycle everyone cites
Today bitcoin is at $90,395, about 31 percent above the previous cycle’s peak. It’s a new high, but it hasn’t filled that reservoir. Whoever bought in 2021–2022 is only just back to break-even. Whoever bought in 2023 has made money, but without the multiples that justify moving capital into riskier things.
Working backwards, bitcoin would have to be between a hundred and fifty and a hundred and eighty thousand dollars to reach conditions like those of 2020. Read it less as a price forecast than as the size of the reservoir a rotation would need for fuel.
What dominance and the indexes say
For comparison, during the 2021 alt season that same share fell from seventy to thirty-nine percent. We’re seeing nothing like it here, and the difference is one of kind before it is one of size.
The index that tries to measure the alt season with a single figure touched eighty-seven at the start of December, above the seventy-five that usually declares one open, and went straight back toward fifty. A shape like that, a spike and a return, is the typical signature of a false start.
Over recent months Bitcoin’s share of the market’s total value has swung between 54 and 61.5 percent. During the 2021 alt season that same share had fallen from 70 to 39 percent. The index that measures the alt season touched 87 at the start of December and went back toward 50.
The channel that stays shut
Until ethereum shows strength against bitcoin, a rotation into the smaller coins is unlikely, because the middle step would be missing. Anyone buying the small ones directly is betting that capital skips the channel. That has never happened in previous cycles.
This cycle, though, has two new elements that could change the rules. The first is the bitcoin ETFs. They opened a way in for institutional capital that stays in bitcoin by mandate and will never rotate, so the reservoir is smaller than the market value suggests. The second is the sheer number of projects. In 2020 liquidity concentrated on a few hundred names. Today it spreads across thousands, so the same money produces much smaller moves.
How I position, and what would change my mind
The most common mistake, and the most expensive, is getting in early. Buy altcoins too soon and you lag bitcoin for months, losing capital in relative terms even while dollar prices rise. It’s a loss you don’t see in your portfolio balance, but you see it perfectly well in the comparison.
Three signals would change my mind, and all three are measurable: bitcoin’s share falling steadily rather than in fits and starts, the ethereum-to-bitcoin ratio really turning, and the coins beating bitcoin staying above half. While they stay where they are today, the position stays as it is.
The three signs of rotation: Bitcoin’s share of the market’s total value falling continuously and not in jerks; the ratio between Ethereum and Bitcoin reversing its multi-year trend; the share of coins beating Bitcoin over ninety days steadily above half.
